TOWING CONNECTOR FOR TRAILER LIGHTS D Your vehicle is equipped with a wire harness stored in the rear end under body. Some models are fitted with a socket for trailer lights under the rear bumper. Use either of them to connect and operate the trailer lights. However, the trailer lights must comply with fed- eral, state/provincial and local regula- tions. See your local recreational ve- hicle dealer or rental agency for the correct type of wiring and relays for your trailer. Check for correct operation of the turn signals and stop lights each time you hitch up. Direct splicing may damage your vehicle’s electrical system and cause a malfunction of your lights. 7−pin connector towing pack- age)—This can be also connected to the trailer brake and trailer sub battery.

BREAK−IN SCHEDULE D Toyota recommends


that you do not tow a trailer with a new vehicle or a vehicle with any new power train com- ponent (engine, transmission, differen- tial, wheel bearings, etc.) for the first 800 km (500 miles) of driving.


MAINTENANCE D If you tow a trailer, your vehicle will require more frequent maintenance due to the additional load. For this informa- tion, please the scheduled maintenance information in the “Sched- uled Maintenance Guide” or “Owner’s Manual Supplement”.

D Check that your rear view mirrors con- form to any applicable federal, state/ provincial or local regulations. If not, install the rear view mirrors required for towing purposes.


TRAILER TOWING TIPS When towing a trailer, your vehicle will handle differently than when not tow- ing. The three main causes of vehicle− trailer accidents are driver error, exces- sive speed and improper trailer loading. Keep these in mind when towing: D Before starting out, check operation of the lights and all vehicle−trailer connec- tions. After driving a short distance, stop and recheck the lights and con- nections. Before actually towing a trail- er, practice turning, stopping and back- ing with a trailer in an area away from traffic until you learn the feel.


D Backing with a trailer is difficult and requires practice. Grip the bottom of the steering wheel and move your hand to the left to move the trailer to the left. Move your hand to the right to move the trailer to the right. (This pro- cedure that when backing without a trailer). Also, just turn the steering wheel a little at time, avoiding sharp or prolonged turning. Have someone guide you when backing to reduce the risk of an acci- dent.

D Because stopping distance may be in- vehicle−to−vehicle distance creased, should be towing a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and trailer length between you and the ve- hicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control. This is especially true on wet or slippery surfaces.


D Avoid jerky starts or sudden accelera- tion. If your vehicle has a manual transmission, prevent excessive clutch slippage by keeping engine rpm low and not racing the engine. Always start out in first gear.


D Avoid jerky steering and sharp turns. The trailer could hit your vehicle in a tight turn. Slow down before making a turn to avoid the necessity of sudden braking.


D Remember that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Therefore, compensate for this by making a turning radius with your vehicle.

larger


D Crosswinds and rough roads will ad- versely affect handling of your vehicle and trailer, causing sway. Pay attention to the rear from time to time to pre- pare yourself for being passed by large trucks or buses, which may cause your vehicle and trailer to sway. If swaying happens, firmly grip the steering wheel and immediately but gradually. Never increase speed. Steer straight ahead. If you make no extreme correction with the steering or brakes, the vehicle and trailer will stabilize.

D Be careful when passing other ve- hicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer and be sure you have plenty of room be- fore changing lanes.


D In order to maintain engine braking effi- ciency, do not use fifth gear (manual transmission) or overdrive (automatic transmission).


(at


D Because of the added load of the trail- er, your vehicle’s engine may overheat on hot days temperatures over 30_C [85_F]) when going up a long or steep grade with a trailer. If the engine coolant indicates overheating, immediately turn off the air conditioning (if in use), pull off the road and stop in a safe spot. Refer to “If your vehicle overheats” in Section 4.

D Always place wheel blocks under both the vehicle and trailer wheels when parking. Apply the parking brake firmly. Put the transmission in “P” (automatic) or in first or reverse (manual). Avoid parking on a slope with a trailer, but if it cannot be avoided, do so only after performing the following:


1. Apply the brakes and hold. 2. Have someone place wheel blocks un- der both the vehicle and trailer wheels. 3. When the wheel blocks are in place, the

How to save fuel and make your vehicle last longer Improving fuel economy is easy—just take it easy. It will help make your vehicle last longer, too. Here are some specific tips on how to save money on both fuel and repairs: D Keep your tires inflated at the cor- rect pressure. Underinflation causes tire wear and wastes fuel. See Section 7−2 for instructions.


D Do not carry unneeded weight


in your vehicle. Excess weight puts a heavier the engine, causing greater fuel consumption.

D Avoid lengthy warm−up idling. Once the engine is running smoothly, begin driving—but gently. Remember, howev- er, that on cold winter days this may take a little longer.


D Always keep the automatic transmis- turned on. sion overdrive switch Driving with the overdrive switch off will reduce the fuel economy. (For de- tails, see “Automatic transmission” in Section 1−7.)

D Avoid long engine idling. If you have a long wait and you are not in traffic, it is better to turn off the engine and start again later.


D Avoid engine


lugging or over−rev- ving. Use a gear position suitable for the road on which you are travelling.


D Avoid continuous speeding up and slowing down. Stop−and−go driving wastes fuel.


D Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper dis- tance from other vehicles to avoid sud- den braking. This will also reduce wear on your brakes.


D Avoid heavy traffic or traffic


whenever possible.

D Do not rest your foot on the clutch or brake pedal. This causes premature wear, overheating and poor fuel econo- my.


D Maintain a moderate speed on high- ways. The faster you drive, the greater the fuel consumption. By reducing your speed, you will cut down on fuel con- sumption.

If your vehicle overheats If your engine coolant temperature gauge indicates overheating, if you ex- perience a loss of power, or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure... 1. Pull safely off the road, stop the ve- turn on your emergency hicle and flashers. Put the transmission in “P” (automatic) or neutral (manual) and ap- ply the parking brake. Turn off the air conditioning if it is being used.


2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over or steam, leave the engine running.


CAUTION


To help avoid personal injury, keep the hood closed until there is no steam. Escaping steam or coolant is a sign of very high pressure.

NOTICE


Do not continue driving with a deflated tire. Driving even a short distance can damage a tire and wheel beyond repair.


CAUTION


When jacking, be sure to observe the following to reduce the possi- bility of personal injury: D Follow jacking instructions. D Do not put any part of your body under the vehicle sup- ported by the jack. Otherwise, personal injury may occur.


D Do not start or run the engine while your vehicle is supported by the jack.


D Stop the vehicle on a level firm ground, firmly set the parking brake and put the transmission in “P” (automatic) or reverse (manual). Block the wheel diag- onally opposite to the one be- ing changed if necessary.


D Make sure to set the jack prop- erly in the jack point. Raising the vehicle with jack improper- ly positioned will damage the vehicle or may allow the ve- hicle to fall off the jack and cause personal injury.


D Never get under the vehicle when the vehicle is supported by the jack alone.


D Use the jack only for lifting your vehicle during wheel changing.


D Do not raise the vehicle with


someone in the vehicle.


D When raising the vehicle, do not place any objects on top of or underneath the jack.


D Raise the vehicle only high enough to remove and change the tire.

—Reinstalling wheel nuts


CAUTION


Never use oil or grease on the bolts or nuts. Doing so may lead to overtightening the nuts and damaging the bolts. The nuts may loose and the wheels may fall off, which could cause a seri- ous accident. If there is oil or grease on any bolt or nut, clean it.


Before putting on wheels, remove any corrosion on the mounting surfaces with a wire brush or such. Installation of wheels without good metal−to−met- al contact at the mounting surface can cause wheel nuts to loosen and eventually cause a wheel to come off while driving.


8. Reinstall all the wheel nuts fin-


ger tight.


Reinstall the wheel nuts (tapered end inward) and tighten them as much as you can by hand. Press back on the tire back and see if you can tighten them more.

—Reinstalling wheel ornament


Use only the wheel nut wrench and turn it clockwise to tighten the nuts. Do not use other tools or any addition- al leverage other than your hands, such as a hammer, pipe or your foot. Make sure the wrench is securely en- gaged over the nut. Tighten each nut a little at a time in the order shown. Repeat the process until all the nuts are tight.


CAUTION


D When


lowering the vehicle, make sure all portions of your body and all other persons around will not be injured as the vehicle is lowered to the ground.


D Have the wheel nuts tightened with torque wrench to 110 N·m (11.5 kgf·m, 83 ft·lbf), as soon as possible after changing wheels. Otherwise, the nuts may loosen and the wheels may fall off, which could cause a serious accident.


9. Lower the vehicle completely


and tighten the wheel nuts.

As soon after changing wheels as possible, tighten the wheel nuts to the torque specified in Section 8 with a torque wrench. Have a technician re- pair the flat tire and replace the spare tire with it.


CAUTION


Before driving, make sure all the tools, jack and flat tire are se- curely in place in their storage location to reduce the possibility of personal injury during a colli- sion or sudden braking.


If your vehicle becomes stuck If your vehicle becomes stuck in snow, mud, sand, etc., then you may attempt to rock the vehicle free by moving it forward and backward. If your vehicle is equipped with the “AUTO LSD” system, you can use it in this situation. (For details, see “AUTO LSD system” in Section 1−7.)


CAUTION


Do not attempt to rock the vehicle free by moving it forward and back- ward if people or objects are any- where near the vehicle. During the rocking operation the vehicle may suddenly move forward or backward as it becomes unstuck, causing injury or damage to nearby people or ob- jects.


—After changing wheels 11. Check the air pressure of the re-


placed tire.


Adjust the air pressure to the specifi- cation designated in Section 8. If the pressure is lower, drive slowly to the nearest service station and fill to the correct pressure. Do not forget to reinstall the tire infla- tion valve cap as dirt and moisture could get into the valve core and possibly cause air leakage. If the cap is missing, have a new one put on as soon as possible. 12.Restow all the tools, jack and


flat tire securely.
