recommends

(cid:1) A safety chain must always be used between the towing vehicle and the trailer. Leave sufficient slack in the chain for turns. The chain should cross under to prevent the tongue from dropping to the ground in case it becomes dam- aged or separated. For correct safety chain procedures, follow the hitch or trailer manufacturer’s recommenda- tions.

CAUTION

(cid:1) If the total trailer weight exceeds 453 kg (1000 lb.), trailer brakes are required.

(cid:1) Never tap

into your vehicle’s hy- draulic system as it would lower its braking effectiveness.

(cid:1) Never tow a trailer without using a safety chain securely attached to both the trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of the trailer wandering over into another lane.

’04 4Runner_U (L/O 0409)

TIRES (cid:1) Ensure

that your vehicle’s

tires are properly inflated. See page 370 in Sec- tion 7- 2 and page 396 in Section 8 for instructions.

SERVICE CONNECTOR FOR TOWING BRAKE CONTROLLER Your vehicle is equipped with a service connector for the towing brake controller as shown. Link the connector to the tow- ing brake controller via the sub wire har- ness stored in the glove box. The detailed explanation of the sub wire harness circuit is packed together with the sub wire har- ness. Be sure to position the towing brake con- troller where it does not prevent the driver from operating the pedal. Toyota recommends that the sub wire har- ness be stored in the glove box when it is not in use.

(cid:1) The trailer tires should be inflated to the pressure recommended by the trail- er manufacturer in respect to the total trailer weight.

(cid:1) 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. The towing connector can be also con- nected to the trailer brake and trailer sub battery.

BREAK- IN SCHEDULE (cid:1) 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 bearing, etc.) for the first 800 km (500 miles) of driving.

PRE- TOWING SAFETY CHECK (cid:1) Check that your vehicle remains level when a loaded or unloaded trailer is hitched. Do not drive if the vehicle has an abnormal nose- up or nose- down condition, and check improper tongue load, overload, worn suspension or other possible causes.

for

(cid:1) Make sure the trailer cargo is securely

loaded so that it cannot shift.

(cid:1) 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 purpose.

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: (cid:1) 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.

(cid:1) 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.

(cid:1) 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.

(cid:1) Avoid jerky starts or sudden accelera-

tion.

(cid:1) 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.

(cid:1) 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.

(cid:1) 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.

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: (cid:1) Keep your tires inflated at the cor- rect pressure. Underinflation causes tire wear and wastes fuel. See page 370 in Section 7- 2 for instructions. (cid:1) Do not carry unneeded weight

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

load on

(cid:1) 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.

(cid:1) Put the selector lever into the “D” when engine braking is not required. 5- speed automatic transmission—Driv- ing with the selector lever in “4” will reduce the fuel economy. (For details, see “Automatic transmission (5- speed)” on page 151 in Section 1- 7.) transmission—Driv- 4- speed automatic ing with the selector lever in “3” will reduce the fuel economy. (For details, see “Automatic transmission (4- speed)” on page 156 in Section 1- 7.)

and

(cid:1) 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.

(cid:1) Avoid engine

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

(cid:1) Avoid continuous speeding up and slowing down. Stop- and- go driving wastes fuel.

(cid:1) 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.

(cid:1) Avoid heavy traffic or traffic

whenever possible.

jams

(cid:1) Do not rest your foot on the brake pedal. This causes premature wear, overheating and poor fuel economy.

316

’04 4Runner_U (L/O 0409)

(cid:1) 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.

(cid:1) Keep

front wheels

in proper alignment. Avoid hitting the curb and slow down on rough roads. Improper alignment not only causes faster tire wear but also puts an extra load on the engine, which, in turn, wastes fuel. (cid:1) Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corro- sion.

(cid:1) Keep your vehicle tuned- up and in top shape. A dirty air cleaner, improp- er valve clearance, dirty plugs, dirty oil and grease, brakes not adjusted, etc. all lower engine performance and con- tribute to poor fuel economy.
