Toyota RAV4
What's So Great About the RAV4?The Toyota RAV4s are Toyota's entry in the small Sport-Utility Vehicle (SUV) market. They appeared at dealers in the US in February 1996. They have received many favorable reviews and have a combination of economy, sporty feel, and attractive styling. Here are some opinions from the RAV4 mailing list: Advantages:
Is the RAV4 safe?Crash testing of vehicles is done by the National Highway Traffic Safety Agency (NHTSA) http://www.nhtsa.dot.gov/. The following was summarized from their web site information; go there for complete details. The RAV4's crash test performance was about average. Cars are tested against other cars in their size and weight class. The RAV4 rated 3 Stars (out of 5), indicating a 21 to 35 percent chance of serious injury in a head-on 35 MPH crash with a similar vehicle. These overall results combine the head and chest injury measurements, and the same rating was given to both the driver and front-seat passenger. Can I order a RAV4 with only the options I want?In the US, some regions allow factory orders and some do not. In regions that do allow factory orders, not all dealers allow them. If your dealer does take factory orders, you can expect to wait at least several months for the car to be shipped. If you have information about which regions do or do not allow factory orders, let me know so I can add that here. Some dealers say they will take a factory order, when in fact they don't. These dealers simply wait for a car that matches or nearly matches your order to arrive by chance. They may be able to access information about all vehicles shipped to your region and/or swap cars with another dealer. Where do I get one of those cute little paper RAV4 models?You can't. These were included in the 1996 RAV4 US brochure and are no longer available. The model is a clever heavy paper cutout that you fold and insert tabs into slots to form a '96 Bright Red 2-Door RAV4. However, you can get a scanned-in version online that you can print with your color printer onto thick paper stock and get a reasonable imitation. See: http://rav4world.com/index/foldup.html. How does the RAV4 compare to the competition?This is a very subjective area, but in general, the RAV4 compares very well to it's competition. People like the RAV4 for it's combination of visual appeal ("cuteness"), good fuel economy, versatile FT 4WD system (fair off-road and excellent on-road), comfort, space, handling, acceleration, accessibility, and reliability. The RAV4 does have it's drawbacks, notably it's styling, lack of power, lack of space (compared to full-size sport-utilities), cheap construction in places, crashworthiness, mediocre sound system, and interior noise levels. Primary U.S. competitors as compared to the RAV4: Honda CR-V: much more conservative styling (often compared to a minivan), reactive 4WD system. Same reliability as Toyota, more interior room, more powerful engine. Worse off-road performance. Kia Sportage: Cheap. Poor engineering touches all around. Rough ride, uncomfortable seating, difficult access to cargo area. Subaru Forrester: Styling like a station wagon. Very car-like ride, low ground clearance, comfortable. Reactive 4WD system, similar to CR-V. Fuel efficient. Full-featured, excellent value. Suzuki Grand Vitara: Poor construction dominates the overall comments about this vehicle; inexpensive, but shows it. More horsepower, but doesn't seem to use it well, and correspondingly worse gas mileage. Good off-road vehicle for the price. How do I "break in" my new RAV4?"For those interested (and many of you might be as you'd have a new RAV4), these are some of the things I do when I run-in a new vehicle. The process is usually useful for the first 5,000 kms or 3,500 miles. (Disclaimer: If you choose to follow any of the tips here, I accept no responsibility for any damage or loss resulting). First of all, why run-in a new vehicle? The reason is that the manufacturing process of metal parts leaves them with some minute imperfections and also they are being mated against other parts. Running-in enables these parts to interface more smoothly by causing a certain degree of beneficial wear and also by wearing down the imperfections. Note that they aren't defects in any sense. A visible example would be on new tires where you see stuff that looks like 'hair' sticking out. As you drive around, they get worn off. Over the past decade, manufacturing processes have improved a lot and the parts are coming out more perfect in form and tolerances are finer. So the running-in process is not as crucial - but still important - as before when you even had to use special oil which permitted a higher wear rate. New engines are tight because everything's new so some degree of wear has to occur to allow them to rev freely. But unlike a decade or two ago, you don't have to be as 'religious' about running-in and I note that the manuals are now providing only basic and simple advice. In fact, the notion of treating a new engine with tender loving care contrasts to what you will find if you visit an engine factory. The new engines, after assembly but before installation in the car, are run at high revs by a computer. It provides some running-in and also allows for checking of integrity or whatever. But to see it being done can be quite shocking! You still need to run-in a new car and engine, allow the various parts to bed in and function with each other efficiently. This calls for thoughtful driving strategies but they are not necessarily boring. The main thing to remember is not to allow your engine to load up, meaning you don't try to drive it up an incline in top gear and labor the engine. The load is bad for the engine at any time, more so when it's brand new. The effects can be long-lasting and ruin the engine's ability to give its best for the rest of its life. Even if you have an autobox, it's a good idea to manually disengage the overdrive on an incline or even slot into 2nd. You won't hurt the engine by doing that and you will even do it a favor if you help it to run up the incline with less effort. Using the gearbox, auto or manual, liberally is a good way to run it in and you will be rewarded by a smoother unit later on. Varying the speed is also an important point and it is mentioned in the manual. This exercise is intended to get your engine used to high and low revving conditions. If you have cruise control, don't use it for at least 3,500 miles because the constant speed is not good. Even on the highway, you should vary your speed a lot. You can do so as you drive by using lower gears and shifting up and down. But you should also pay attention to what rpm you run up to. For the first few 100 miles, maybe you shouldn't get past 4000 rpm. Then you can gradually go higher and by maybe 1500 miles, you can start to push it to 5000 rpm. Do not run it up to 5000 rpm and just hold it there; rev it up as you're driving and change up quickly when you get to 5000 rpm. When you get up to 2000 miles or more, maybe you might like to try running it up to the redline for brief spurts. I learnt that this is helpful for the engine from a racing driver and mechanic. You accelerate in 2nd gear up the the redline and shift up right away. Don't hold it there longer than a shift action. Why? The high revs give the engine a 'taste' of that sort of condition and prepares it for the ability to cope with such conditions. It's like when you do a high-speed run down the highway and after that, the engine feels nice and free-revving (although that's more of the oil being well circulated too). If you stick to low revs all the time, there is a possibility that your engine will remain tight and unwilling to give all its potential when you want to drive hard and fast. I have experienced engines where the owners really pussy-footed them in the run-in period and they never had an edge in performance compared to other similar engines. The manual doesn't seem to recommend an oil change at 1000 km (600 mi) but I am used to it and will do so. No harm and the only thing that will be hurt is my pocket. I personally believe that the first 600 miles are a time of great wear inside and so the oil will have a lot of metal stuff in it. The filter will remove it, of course, but it's still there and it's minute too. I'd rather get rid of the dirty oil and have some new oil inside; besides, the original oil is of unknown quality to me although I'm sure Toyota would use something good enough. The next oil change would be at 5000 kms or 3500 miles, but you can follow the interval indicated in your manual. For the brakes, I also take a bit of care. You need to brake a lot to run-in the new pads but you also have to be cautious about how hard you brake. Excessive pressure on new pads can cause them to glaze over and that's going to reduce braking power. Some people drive around with a very light pressure for a while to wear them out a bit but you need to really be deliberate about that. Other things: I like to use Rain-X, a liquid which makes the glass very slippery so that water beads off easily. I put it on the front and back, the front side windows and the door mirrors. It's corrosive so don't let it get on your paintwork! I also like to spray on fabric protector which helps to stop moisture from seeping in (most of the time). And I've earlier mentioned the point about loose screws and bolts. Take a screwdriver and small spanner (preferably a box type) and gently tighten the fasterners you can see. Not too tight but if you find them able to take another turn, then do so. From experience, I've always found the bolts holding the front fenders to the body (along the side of the engine bay) to be less than tight (same thing in the RAV4)." When should I change the oil the first time, and what kind should I use?Some people think that a lot of metal particles and assorted gunk collect during the break-in period, so they get the oil changed at around 500-1500 miles, or 800-2400 km. You should then follow the schedule in your owner's manual (every 7500 miles (12000 km) for regular service, or every 3750 miles (6000 km) for severe service) as the minimum oil change interval. The extra oil change is considered by many to be cheap insurance. Also, average driving often falls under "severe" conditions that require more frequent oil changes. The manual recommends using 5W-30 or 10W-30 SG oil, depending on the expected temperature during the oil's service life. The 10W-30 should not be used under extreme cold conditions (below 0 F). You can use a conventional oil, or synthetic. Synthetic oil has better heat and cold handling characteristics, and resists viscosity breakdown much better than conventional oil, but is significantly more expensive. How does the Four Wheel Drive (4WD) system work?Very well :) Actually, it depends on your choice of transmission, and whether you have the Limited-Slip Differential (LSD) option. See the Traction Adding Devices FAQ http://www.a1.nl/phomepag/markerink/diffs.htm for more general information on these types of devices. If you have a 2-Wheel-Drive RAV4, then it is powered by the front wheels only. If you have 4WD, a full-time system puts power down to all four wheels at all times. Some refer to this as an "all-wheel drive" system, rather than 4WD, but AWD usually refers to "reactive" systems that delay transfer of power until after slip is detected. The RAV4 drive system is most correctly called "Full-time 4 wheel drive." It is reported that 25% of the engine power is normally sent to each wheel.
What should I expect when Anti-Lock Brakes (ABS) engage?You should get feedback in the form of an audible "chunk chunk chunk" sound AND a strong pulsing of the brake pedal. This is normal and you should NOT release the pressure on the brake pedal or attempt to modulate the brake pedal pressure. If you live in the snow belt, a good way to test your ABS is to find an open, snow-covered area, drive to about 30MPH, and slam on the brakes as hard as you can. The described effect should be obvious. Warning: Don't test or show off your ABS system until after the break-in period, because it can create hot spots that can cause excessive brake system wear. How can I keep from getting a shock when I exit my RAV4?Method 1: Get a conductive strap that bolts to the frame - when you stop, the end contacts the ground and bleeds the charge off the car. These work well, but wear out rather quickly. Method 2: Keep your hand on the edge of the door (or any metal part) as you exit the vehicle. Method 3: Whenever you exit your vehicle, hold your key and make sure that the first thing you touch after you exit is made of metal, and that you touch it with your key first. This will dissipate any static electricity. Method 4: a quick spray of a product such as Static Guard also helps to eliminate the static buildup from rubbing on the cloth seats. (Thanks to Jim Janecek <Janecek@Tezcat.com>) Method 5: Drive naked. Then you won't build up any static electricity between you and your clothes. If you wet your pants, that should dissipate the excess charge as well. <g> Also from Jim Janecek: "You might want to also check the type of tires on vehicle, if they are 'low rolling resistance' tires they may have more of a silicone base instead of a carbon base and this does not allow the static charge that normally builds up on a object moving through the air to disperse through the tires. The silicone base is more of an insulator than the carbon base. Unfortunately, I don't have a list of what tires have the silicone base and what have the usual carbon base in them. I just know that Michelin had a series of 'low rolling resistance' tires that came as factory standard on some recent (2-3 year old) model Hondas and they would not allow the static buildup to bleed off into the ground through the tires, so when you stopped at a toll booth and touched the tollbooth operator, the operator would get a real big shock." What should the fuel economy (Miles per Gallon) be?First, remember that your MPG will vary depending on many factors:
To compute MPG, you should average stats over a number of fillups and make sure you fill your gas tank to the same level each time, preferably using the same gas pump at the same station, if practical. The Environmental Protection Agency http://www.epa.gov tests all vehicles sold in the US and publishes fuel economy estimates. The RAV4 mileage depends on transmission and whether the vehicle has 4WD: For 2001: Drive, Transmission City/Highway estimate 2WD, 5-speed 24/29 For 2000: Drive, Transmission City/Highway estimate (could someone please send me these numbers?) For 1998: Drive, Transmission City/Highway estimate 2WD, 5-speed 24/28 For 1997: Drive, Transmission City/Highway estimate 2WD, 5-speed 24/30 For 1996: Drive, Transmission City/Highway estimate 2WD, 5-speed 24/30 If your fuel economy is significantly below these estimates, and cannot be accounted for by any other factors, you should see your dealer service department for diagnosis. Note that many drivers report that fuel economy can be poor when the vehicle is new, gradually improving to acceptable levels through the break-in period. What kind of fuel should I use?The owner's manual recommends 87 octane regular unleaded fuel. The RAV4 is not designed to take advantage of higher octane gas, so while putting it in will not harm your vehicle, you will receive no benefit and the cost is significantly higher. If you are hearing a "knock" or "rattle" sound from your engine during high load, and the problem is reduced or eliminated by higher octane gas, then you probably need an engine tune-up. How much gas can I put in my RAV?The owner's manual says that the RAV4 has a 15.2 US Gallon tank. Most people report that they can fit about 13-14 gallons in when they fill up soon after the low fuel warning light has come on. This should give the RAV4 a typical range of 250-350 miles between fill ups, and about 30-60 miles of driving after the low fuel warning light has come on. Is my Fuel Gauge Inaccurate?Due to the shape of the gas tank (best described as an Inverted U), the fuel gauge does not show fuel use linearly. Most report that it is fairly linear from Full to 25%, then drops rapidly. Others say it tends to go from Full to 75% very quickly, then goes down at a steady rate. In any case, you should refuel as soon after the low fuel warning light comes on as possible. Is brake noise normal?Sometimes, you will hear a high-pitched squeak or squeal as the brakes are applied. This problem happens on any car due to dirt getting into the brakes. Although you can have a reputable dealer check it out, it's usually just bad luck to get squeaky dirt in the brakes. What size are the tires?RAV4 tires are delivered in one of two sizes, depending on the option packages that were ordered. Most RAV4s are delivered with tires with a size designation of P215/70R16. The alternate size is P235/60R16. You can easily determine the size of your tire by reading the size code stamped into the sidewall. The first number in the size code is the width of the tire, measured from sidewall to sidewall, in millimeters. To convert to inches, divide by 25.4. For example, the width of 215mm is equal to 8.46". The second number is the aspect ratio, or the ratio of sidewall height to width. For the RAV4, the 70 indicate that the height of the sidewall is .70 of the width. So, the height of the tire sidewall is 215mm X .70 = 150.5mm or 8.46" X .70 = 5.93". The "R" indicates a Radial tire design. Virtually all tires available today are of this design. The last number is the diameter of the wheel in inches. Often, tires and wheels are replaced as a set for various reasons. When a "plus 1" wheel is used, the driver wants better handling characteristics. A wheel one inch larger than stock is installed, and tire with a correspondingly smaller sidewall height is chosen to retain the same diameter of the tire. Maintaining tire diameter is important to keep speedometer and odometer readings accurate. In the same way, a "minus 1" tire and wheel package may be installed, often for a snow tire package. A wheel one inch smaller is installed with a tire with a correspondingly larger sidewall height. A taller, skinnier tire performs better in the snow. To calculate the differences in wheel and tire size, use this tire size calculator: http://www.powerdog.com/tiresize.cgi At what pressure should I keep the tires?According to the owner's manual and the driver's door sticker, the stock tires should be inflated to 28 psi front and 26 psi rear. You can increase the pressure to get a stiffer ride, more responsive feel, and slightly increased fuel economy, but do not exceed the recommendation stamped into the sidewall of the tire. Most drivers keep their tires inflated to between 28 - 30 psi, providing a good compromise between performance and comfort. You should experiment with tire pressures and go with what works best. Note that there are also certain low-traction situations (such as driving on sand) where lowering tire pressure can improve handling. I has been noted by several owners that their vehicles were delivered with tires inflated to 40-50 psi. It is reported that Toyota ships their vehicles like this to prevent flat spots on the tires in transit. Some dealers apparently forget to check this; the result is a very harsh ride and a potential for premature tire wear. All owners should check their tires as soon as practical after taking delivery. What should I buy to replace my worn tires?It very much depends on how you drive your RAV4. Tires are always an exercise in tradeoffs; for example, harder rubber compounds last a long time, but tend to be noisy and provide worse traction than softer rubber compounds that don't last as long. Tires are also designed for different environments. Tires with aggressive tread designs are better in snow and ice, but generate more road noise. Others with less aggressive treads are better on dry pavement and are quiet, but are bad, even dangerous, in the snow. Most people replace their worn tires with a type similar to what is shipped on their RAV4 - all-season tires. These tires are a general compromise between most normal driving conditions. They are adequate for all of them, but excel in none of them. They have a moderately aggressively tread pattern that is good in rain and snow, but it not excessively noisy. They are designed to last for 40,000 to 60,000 miles under normal use. With the Full-Time 4WD that most RAV4s have, these tire are all that most people will ever need. Some people who live in the "snow belt" maintain 2 sets of tires, often on separate wheels; one set of tires that are designed for good performance on wet and dry surfaces, and one set that are for winter driving exclusively. The wet/dry tires provide better performance and tire life, while the winter tires are excellent for snow and ice conditions. This helps eliminate many of the compromises of all-season tires at the cost of an extra set of tires and the inconvenience of installing them each winter. Still others do extensive off-road driving. They require special tires for this purpose that maintain traction in sand, mud, and other harsh conditions. They may install these tires only when they plan to drive off-road. Why doesn't my factory jack lift the vehicle off the ground?The factory jack, which is stored under the passenger's seat, will lift a RAV4 tire off the ground if the correct lift point under the vehicle is used. You should not need to use a board or other extension to use the jack. The exact lift points are vaguely pictured in the owner's manual. The lift points are the shape of a small tab that fits into a corresponding slot on the lifting surface of the jack. These points are not on the frame of the vehicle, as on most cars, but on the suspension. In the front, the lift points are behind the wheels, slightly to the rear of the wheel center. In the rear, the lift point is several inches in from the edge of the body just forward of the rear wheel. On sensible suggestion is to find the lift points at a convenient time and then clean and paint them a bright color. That will make finding them at a less convenient time easier. What are the ECT and OD buttons on my automatic transmission for?The ECT button (which stands for "Electronically Controlled Transmission") changes the shift points for the automatic transmission. When engaged, the transmission shifts later, allowing the engine to get to a higher power level and accelerate faster. Gas mileage is usually reduced in this mode. Use it when you need to get up to speed faster; for example, to merge into fast moving traffic. The normal position for this switch is OFF. OD, or OverDrive, is a 4th gear on the transmission that will engage when you are going above about 35 mph that lets the engine operate at a lower speed (RPMs) when all it has to do is maintain a high speed when you are going over flat, even highway. This improves fuel economy. Technically, any transmission gear with a ratio of less than 1:1 is considered "OverDrive". OD can normally be left ON except when going up a gradual hill; the overdrive tends to not give the engine enough power to maintain a steady speed. This may cause the transmission to annoyingly "hunt" between 3rd and 4th gear. Why does the A/C come on when I use the defroster?It's supposed to. The owner's manual is specific about this feature. The idea is that whenever you need the windshield cleared, the air conditioner will come on to help get the job done. The A/C not only provides cool air when it's hot outside, but it also dehumidifes the air. Dehumidified air is much less likely to cause the windshield to fog up. Many cars have this feature without their drivers even knowing about it. Some people even contend that the primary purpose of the A/C is to dehumidify the air, and cooling is a happy side effect. In any case, if the conditioned air is too cold for you, just add a little heat by sliding the temperature lever to the right a bit. That said, use of the A/C does cause a reduction in both available power and gas mileage. Most estimates I've seen are in the 10% range, but this kind of drop is especially noticable in a vehicle like the RAV4, with a small engine and relatively low horsepower. Some drivers would prefer to have complete control over whether or when the A/C comes on because of the penalties. The easiest way is to disable the A/C in defrost mode is to move the control lever all the way to the right (full defrost), then move it slightly to the left until the A/C turns off.
