Off–road vehicle precautions

242

’03 4Runner_U (L/O 0305)

This vehicle belongs to the utility ve- hicle class, which has higher ground clearance and narrower tread in relation to the height of its center of gravity to make it capable of performing in a wide variety of off–road applications. Specific design characteristics give it a higher center of gravity than ordinary passen- ger cars. This vehicle design feature causes this type of vehicle to be more likely to rollover. And, utility vehicles have a significantly higher rollover rate than other types of vehicles. An advan- tage of the higher ground clearance is a better view of the road allowing you is not de- to anticipate problems. signed the same speeds as ordinary passenger cars any more than low–slung sports cars de- signed to perform satisfactorily under off–road conditions. Therefore, sharp turns at excessive speeds may cause rollover.

It for cornering at

CAUTION

Always observe the following precau- tions to minimize the risk of serious personal injury or damage to your ve- hicle: (cid:1) In a rollover crash, an unbelted per- son is significantly more likely to die than a person wearing a seat belt. Therefore, the driver and all passengers should fasten their seat belts whenever the vehicle is mov- ing.

(cid:1) Avoid sharp turns or abrupt maneu- vers, if at all possible. Failure to operate this vehicle correctly may result in loss of control or vehicle rollover causing death or serious injury.

(cid:1) Loading cargo on the roof luggage carrier will make the center of the vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneu- vers, otherwise it may result in loss of control or vehicle rollover due to failure to operate this vehicle cor- rectly.

(cid:1) When driving off–road or in rugged terrain, do not drive at excessive speeds, turns, strike objects, etc. This may cause loss of control or vehicle rollover causing death or serious injury. You are also risking expensive damage to your vehicle’s suspension and chassis.

(cid:1) Do not drive horizontally across steep slopes. Driving straight up or straight down is preferred. Your ve- hicle (or any similar off–road ve- hicle) can tip over sideways much more easily than forward or back- ward.

Break–in period Drive gently and avoid high speeds. Your vehicle does not need an elaborate break–in. But following a few simple tips for the first 1600 km (1000 miles) can add to the future economy and long life of your vehicle: (cid:1) Avoid full

throttle acceleration when

starting and driving.

(cid:1) Avoid racing the engine. (cid:1) Try to avoid hard stops during the first

300 km (200 miles).

(cid:1) Do not drive for a long time at any

single speed, either fast or slow.

(cid:1) Do not tow a trailer during the first 800

km (500 miles).

Fuel FUEL TYPE Your new vehicle must use only un- leaded gasoline. To help prevent gas station mix–ups, your Toyota has a smaller fuel tank opening. The special nozzle on pumps with un- leaded fuel will fit it, but the larger stan- dard nozzle on pumps with leaded gas will not. At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB 3.5–M93
in Canada.

NOTICE

Do not use leaded gasoline. Use of leaded gasoline will cause the three– way catalytic converter to lose its ef- fectiveness and the emission control system to function improperly. Also, this can increase maintenance costs.

OCTANE RATING Select Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher is recommended. Use of unleaded gasoline with an octane rating or research octane number lower than stated above will cause persistent heavy knocking. If it is severe, this will lead to engine damage. If your engine knocks... If you detect heavy knocking even when using if you hear steady knocking while holding a steady speed on level roads, consult your Toyota dealer. However, occasionally, you may notice light knocking for a short time while accel- erating or driving up hills. This is normal and there is no need for concern. GASOLINE CONTAINING DETERGENT ADDITIVES Toyota recommends the use of gasoline that contains detergent additives to avoid build–up of engine deposits.

for quality

However, all gasoline sold the U.S. contains detergent additives to keep clean and/or clean intake systems. QUALITY GASOLINE Automotive manufacturers in the U.S., Europe and Japan have developed a specification fuel named World–Wide Fuel Charter (WWFC) that is expected to be applied world wide. The WWFC consists of three categories that depend on required emission lev- els. In the U.S., category 3 has been adopted. The WWFC improves air quali- ty by providing for better emissions in vehicle fleets, and customer satisfaction through better vehicle performance. CLEANER BURNING GASOLINE Cleaner burning gasoline, including re- formulated gasoline that contains oxy- genates such as ethanol or MTBE is available in many areas. Toyota recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gas- oline provide excellent vehicle perfor- mance, reduce vehicle emissions, and im- prove air quality.

If you use gasohol

OXYGENATES IN GASOLINE Toyota allows the use of oxygenate blended gasoline where the oxygenate content is up to 10% ethanol or 15% MTBE. in your Toyota, be sure that it has an octane rating no lower than 87. Toyota does not recommend the use of gasoline containing methanol. GASOLINE CONTAINING MMT Some gasoline contain an octane en- hancing additive called MMT (Methylcy- clopentadienyl Manganese Tricarbonyl). Toyota does not recommend the use of gasoline that contains MMT. If fuel con- taining MMT is used, your emission con- trol system may be adversely affected. The Malfunction Indicator Lamp on the in- strument cluster may come on. If this hap- pens, contact your Toyota dealer for ser- vice. GASOLINE QUALITY In a very few cases, you may experience driveability problems caused by the partic- ular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If this does not rectify your problem, then consult your Toyota dealer.

Three–way catalytic converters

1GR–FE engine

2UZ–FE engine

246

’03 4Runner_U (L/O 0305)

The three–way catalytic converter is an emission control device installed in the exhaust system. The purpose is to reduce pollutants in the exhaust gas.

CAUTION

(cid:1) Keep people and combustible mate- rials away from the exhaust pipe while the engine is running. The exhaust gas is very hot.

(cid:1) Do not

idle or park your vehicle over anything that might burn easi- ly such as grass, leaves, paper or rags.

NOTICE

A large amount of unburned gases flowing into the three–way catalytic converter may cause it to overheat and create a fire hazard. To prevent this and other damage, observe the following precautions: (cid:2) Use only unleaded gasoline. (cid:2) Do not drive with an extremely low fuel level; running out of fuel could cause the engine to misfire, creat- ing an excessive load on the three– way catalytic converter.

(cid:2) Do not allow the engine to run at idle speed for more than 20 min- utes.

(cid:2) Avoid racing the engine. (cid:2) Do not push–start or pull–start your

vehicle.

(cid:2) Do not turn off the ignition while

the vehicle is moving.

2003 4RUNNER from Apr. ’03 Prod. (OM35820U)

’03 4Runner_U (L/O 0305)

(cid:2) Keep your engine in good running order. Malfunctions in the engine electrical system, electronic ignition system/distributor ignition system or fuel systems could cause an ex- tremely high three–way catalytic converter temperature.

(cid:2) If the engine becomes difficult to start or stalls frequently, take your vehicle in for a check–up as soon as possible. Remember, your Toyota dealer knows your vehicle and its three–way catalytic converter sys- tem best.

(cid:2) To ensure that the three–way cata- lytic converter and the entire emis- sion control system operate proper- ly, your vehicle must receive the periodic inspections required by the Toyota Maintenance Schedule. For scheduled maintenance information, refer to the “Scheduled Maintenance Guide” or “Owner’s Manual Supple- ment”.

Engine exhaust cautions

CAUTION

(cid:1) Avoid inhaling the engine exhaust. It contains carbon monoxide, which is a colorless and odorless gas. It can cause unconsciousness or even death.

(cid:1) Make sure the exhaust system has no holes or loose connections. The system should be checked from time to time. If you hit something, or notice a change in the sound of the the system exhaust, have checked immediately.

(cid:1) Do not run the engine in a garage or enclosed area except the time needed to drive the vehicle in or out. The exhaust gases cannot escape, making this a particularly dangerous situation.

for

(cid:1) Do not remain for a long time in a parked vehicle with the engine run- ning. If it is unavoidable, however, do so only in an unconfined area and adjust the heating or cooling system to force outside air into the vehicle.

(cid:1) Keep the back door and back win- dow closed while driving. An open or unsealed back door and back window, may cause exhaust gases to be drawn into the vehicle.

(cid:1) To allow proper operation of your vehicle’s ventilation system, keep the inlet grilles in front of the wind- shield clear of snow, leaves, or oth- er obstructions.

(cid:1) If you smell exhaust fumes in the the windows vehicle, drive with open and the back door and back window closed. Have the cause im- mediately located and corrected.

Facts about engine oil consumption FUNCTIONS OF ENGINE OIL Engine oil has the primary functions of lubricating and cooling the inside of the engine, and plays a major role in main- taining the engine in proper working order. ENGINE OIL CONSUMPTION It is normal that an engine should con- sume some engine oil during normal engine operation. The causes of oil consumption in a normal engine are as follows. (cid:1) Oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a pis- ton moves downwards in the cylinder. High negative pressure generated when the vehicle is decelerating sucks some of this oil into the combustion chamber. This oil as well as some part of the oil film left on the cylinder wall is burned by temperature combustion gases during the combustion process.

the high

intake air and

the

The amount of engine oil consumed de- pends on the viscosity of the oil, the quality of the oil and the conditions the vehicle is driven under. More oil is consumed by high–speed driv- ing and frequent acceleration and decel- eration. A new engine consumes more oil, since its pistons, piston rings and cylinder walls have not become conditioned. Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 lmp. qt./600
miles) When judging the amount of oil con- sumption, note that the oil may become diluted and make it difficult to judge the true level accurately.

As an example, if a vehicle is used for repeated short trips, and consumes a nor- mal amount of oil, the dipstick may not show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is then driven at high speeds, as on an expressway, making it appear that oil is excessively consumed after driving at high speeds. IMPORTANCE OF ENGINE OIL LEVEL CHECK One of the most important points in prop- er vehicle maintenance is to keep the en- gine oil at the optimum level so that oil function will not be impaired. Therefore, it is essential that the oil level be checked regularly. Toyota recommends that the oil level be checked every time you refuel the vehicle.

NOTICE

Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.

BRAKE BOOSTER The brake booster uses brake fluid pres- surized by the pump to power–assist the brakes. If the brake booster fails during driving, light comes on and buzzer sounds continuous- ly. In this case, the brakes may not work properly. If they do not work well, depress the brake pedal firmly. If the brake system warning light comes on, immediately stop your vehicle and contact your Toyota deal- er. It is not a malfunction that the brake sys- tem warning light may stay on for 60 sec- onds after the ignition key is turned to the “ON” position.

You may hear a small sound in the engine compartment after the engine is started or the brake pedal is depressed repeatedly. This is a pump pulsating sound of the brake system, and it is not a malfunction.

ANTI–LOCK BRAKE SYSTEM (with “ABS” warning light) The anti–lock brake system is designed to help prevent lock–up of the wheels during a sudden braking or braking on slippery road surfaces. This assists in providing directional stability and steer- ing performance of the vehicle under these circumstances.

this situation,

Effective way to press the ABS brake pedal: When the anti–lock brake system function is in action, you may feel the brake pedal pulsating and hear a noise. In the anti–lock brake system work for you, just hold the brake pedal down more firmly. Do not pump the brake in a panic stop. This will result in reduced braking performan- ce.

let

to

The anti–lock brake system becomes op- erative after the vehicle has accelerated to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the vehicle decelerates to a speed below approximately 5 km/h (3 mph).

Depressing the brake pedal on slippery road surfaces such as on a manhole cov- er, a steel plate at a construction site, joints in a bridge, etc. on a rainy day tends to activate the anti–lock brake sys- tem. You may hear a click or motor sound in the engine compartment for a few seconds when the engine is started or just after the vehicle begins to move. This means that the anti–lock brake system is in the self–check mode, and does not indicate a malfunction. When the anti–lock brake system is ac- tivated, the following conditions may occur. They do not indicate a malfunc- tion of the system: (cid:1) You may hear the anti–lock brake sys- tem operating and feel the brake pedal pulsating and the vibrations of the ve- hicle body and steering wheel. You may also hear the motor sound in the engine compartment even after the ve- hicle is stopped.

CAUTION

Do not overestimate the anti–lock brake system: Although the anti–lock brake system assists in providing ve- hicle control, it is still important to drive with all due care and maintain a moderate speed and safe distance from the vehicle in front of you, be- cause there are limits to the vehicle stability and effectiveness of steering wheel operation even with the anti– lock brake system on. If tire grip performance exceeds its capability, or if hydroplaning occurs during high speed driving in the rain, the anti–lock brake system does not provide vehicle control. Anti–lock brake system is not de- signed to shorten the stopping dis- tance: Always drive at a moderate speed and maintain a safe distance from front of you. Compared with vehicles without an anti–lock brake system, your vehicle may require a longer stopping dis- tance in the following cases: (cid:1) Driving on rough, gravel or snow–

(cid:1) Driving on roads where the road surface is pitted or has other differ- ences in surface height.

Install all 4 tires of specified size at appropriate pressure: The anti–lock brake system detects vehicle speeds using the speed sensors for respec- tive wheels’ turning speeds. The use of tires other than specified may fail to detect the accurate turning speed resulting longer stopping dis- tance.

A warning light turning on briefly during operation does not indicate a problem.

CAUTION

If the “ABS” warning light remains on together with the brake system warn- ing light, immediately stop your ve- hicle at a safe place and contact your Toyota dealer. In this case, not only the anti–lock brake system will fail but also the vehicle will become extremely unsta- ble during braking.

Either of the following conditions may occur, but do not indicate a malfunc- tion: (cid:1) The light may stay on for about 60
seconds after the ignition key is turned to the “ON” position. It is normal if it turns off after a while.

(cid:1) Depressing the brake pedal repeatedly may turn on the light. It is normal if it turns off after a few seconds.

DRUM–IN–DISC TYPE PARKING BRAKE SYSTEM Your vehicle has a drum–in–disc type parking brake system. This type of brake system needs bedding–down of the brake shoes periodically or whenever the parking brake shoes and/or drums are replaced.

Have your Toyota dealer perform the bed- ding–down. BRAKE ASSIST SYSTEM When you slam the brake assist system judges as an emer- gency stop and provides more powerful braking for a driver who cannot hold down the brake pedal firmly. When you slam the brakes on, more pow- erful braking will be applied. At this time, you may hear a sound the engine compartment and feel the vibrations of the brake pedal. This does not indicate a mal- function. The brake assist system becomes opera- tive after the vehicle has accelerated to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the vehicle decelerates to a speed below approximately 5 km/h (3 mph). For an explanation of this system’s warn- ing light, see “Service reminder indicators and warning buzzers” on page 117 in Sec- tion 1–5.

Brake pad wear limit indicators

The brake pad wear limit indicators on your disc brakes give a warning noise when the brake pads are worn to where replacement is required. If you hear a squealing or scraping noise while driving, have the brake pads checked and replaced by your Toyota dealer as soon as possible. Expensive ro- tor damage can result if the pads are not replaced when necessary.

Limited–slip differential (four–wheel drive models) Your Toyota is equipped with a limited–slip center differential (transfer). If one wheel begins to spin, the limited–slip center dif- ferential (transfer) is designed to aid trac- tion by automatically transmitting driving force to the wheels on the other drive axle. It transmits driving force to the front wheels if a rear wheel spins, and to the rear wheels if a front wheel spins.

CAUTION

Do not start or run the engine while your vehicle is supported by a jack. The vehicle could be driven off the jack and could pose a danger or re- sult in serious injury.

NOTICE

Use only a spare tire of the same brand, size, construction and load ca- pacity as the original tires on your Toyota because damage to the limit- ed–slip differential could possibly oc- cur with another tire type.

(cid:1) Never allow anyone to ride in the luggage compartment. It is not de- signed for passengers. They should ride in their seats with their seat belts properly fastened. Otherwise, they are much more likely to suffer serious bodily injury, in the event of sudden braking or a collision.

(cid:1) Do not place anything on the lug- items may be gage cover. Such thrown about and possibly injure people in the vehicle during sudden braking or an accident. Secure all items in a safe place.

(cid:1) Do not drive with objects left on top of the instrument panel. They may interfere with the driver’s field of view. Or they may move during sharp vehicle acceleration or turn- ing, and impair the driver’s control of the vehicle. In an accident they may injure the vehicle occupants.

NOTICE

Do not load the vehicle beyond the cargo load specified on page 352 in Section 8.

Suspension and chassis

CAUTION

Do not modify the suspension/chassis with lift kits, spacers, springs, etc. It can cause dangerous handling charac- teristics resulting in loss of control.

Theft prevention labels (except for Canada) Your new vehicle carries theft preven- tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.). The purpose of these labels is to reduce the incidence of vehicle thefts by facilitat- ing the tracing and recovery of parts from stolen vehicles. The label is designed so that once it is applied to a surface, any attempt to remove it will result in destroy- ing the integrity of the label. Transferring these labels intact from one part to anoth- er, will be impossible.

NOTICE

You should not attempt to remove the theft prevention labels as it may vio- late certain state or federal laws.

Types of tires Determine what kind of tires your ve- hicle is originally equipped with. 1. Summer tires Summer tires are high–speed capability tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, sum- mer tires are inadequate for driving on snow–covered or icy roads. For driving on snow–covered or icy roads, we recom- mend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in accel- eration performance compared with summer tires in highway driving.

Off–road driving precautions When driving your vehicle off–road, please observe the following precautions to en- sure your driving enjoyment and to help prevent the closure of areas to off–road vehicles. a. Drive your vehicle only in areas where off–road vehicles are permitted to trav- el.

b. Respect private property. Get owner’s permission before entering private prop- erty.

c. Do not enter areas

that are closed. Honor gates, barriers and signs that re- strict travel.

d. Stay on established roads. When condi- tions are wet, driving techniques should be changed or travel delayed to pre- vent damage to roads.

For owners in U.S. mainland, Hawaii and Puerto Rico: To obtain additional information pertaining to driving your vehicle off–road, consult the following organizations. (cid:1) State and Local Parks and Recreation

Departments

(cid:1) State Motor Vehicle Bureau

(cid:1) Recreational Vehicle Clubs (cid:1) U.S. Forest Service and Bureau of

Land Management

CAUTION

Always observe the following precau- tions to minimize the risk of serious personal injury or damage to your ve- hicle: (cid:1) Drive carefully when off the road. Do not take unnecessary risks by driving in dangerous places.

(cid:1) Do not grip

the steering wheel spokes when driving off–road. A bad bump could jerk the wheel and injure your hands. Keep both hands and especially your thumbs on the outside of the rim.

(cid:1) Always check your brakes for effec- tiveness immediately after driving in sand, mud, water or snow.

(cid:1) After driving

through

tall grass, mud, rock, sand, rivers, etc., check that there is no grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody. Clear off any such matter from the under- body. If the vehicle is used with these materials trapped or adhering to the underbody, a breakdown or fire could occur.

(cid:1) In a rollover crash, an unbelted per- son is significantly more likely to die than a person wearing a seat belt. Therefore, the driver and all passengers should fasten their seat belts whenever the vehicle is mov- ing.

jump, make sharp

(cid:1) When driving off–road or in rugged terrain, do not drive at excessive speeds, turns, strike objects, etc. This may cause loss of control or vehicle rollover causing death or serious injury. You are also risking expensive damage to your vehicle’s suspension and chassis.

NOTICE

(cid:3) If driving through water, such as when crossing shallow streams, first check the depth of the water and the bottom of the river bed for firmness. Drive slowly and avoid deep water.

(cid:3) Take all necessary safety measures to ensure that water damage to the engine or other components does not occur. Water entering the engine air intake will cause severe engine damage. Water can wash the grease from wheel bearings, causing rusting and premature failure, and may also en- ter the differentials, transmission and transfer case, reducing the gear oil’s lubricating qualities.

(cid:3) Sand and mud that has accumulated in brake drums and around brake discs may affect braking efficiency and may damage brake system com- ponents.

264

(cid:3) Always perform a maintenance in- spection after each day of off–road driving that has taken you through rough terrain, sand, mud, or water. For scheduled maintenance informa- tion, refer to the “Scheduled Main- tenance Guide” or “Owner’s Manual Supplement”.

Winter driving tips Make sure your coolant is properly pro- tected against freezing. Your coolant must contain ethylene–glycol type coolant for a proper corrosion protec- tion of aluminum components. Use “Toyota Genuine Long Life Coolant” or equivalent. See page 326 in Section 7–2 for details about coolant type selection.

NOTICE

Do not use alcohol type antifreeze or plain water alone.

When it is extremely cold, we recommend to use 60% solution for your Toyota, to provide protection down to about –50(cid:2)C (–58(cid:2)F). Do not use more than 70% solu- tion for better coolant performance. Check the condition of the battery and cables. Cold temperatures reduce the capacity of any battery, so it must be in top shape to provide enough power for winter start- ing. Section 7–3 tells you how to visually inspect the battery. Your Toyota dealer and most service stations will be pleased to check the level of charge.

Dinghy towing

Make sure the engine oil viscosity is suitable for the cold weather. See page 324 in Section 7–2 for recom- mended viscosity. Leaving a heavy sum- mer oil in your vehicle during winter months may cause harder starting. If you are not sure about which oil to use, call your Toyota dealer—he will be pleased to help. Keep the door locks from freezing. Squirt lock de–icer or glycerine into the locks to keep them from freezing. Use a washer fluid containing an anti- freeze solution. This product is available at your Toyota dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.

NOTICE

Do not use engine antifreeze or any other substitute because it may dam- age your vehicle’s paint.

in and around

Do not use your parking brake when there is a possibility it could freeze. When parking, put the transmission into “P” and block the front wheels. Do not use the parking brake, or snow or water accumulated the parking brake mechanism may freeze, making it hard to release. Keep ice and snow from accumulating under the fenders. Ice and snow built up under your fenders can make steering difficult. During bad winter driving, stop and check under the fenders occasionally. Depending on where you are driving, we recommend you carry some emer- gency equipment. Some of the things you might put in the vehicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jumper cables, etc.

Trailer towing Your vehicle is designed primarily as a passenger–and–load–carrying vehicle. Tow- ing a trailer will have an adverse effect on handling, performance, braking, durability and driving economy (fuel consumption, etc.). Your safety and satisfaction depend on the proper use of correct equipment and cautious driving habits. For your safe- ty and the safety of others, you must not overload your vehicle or trailer. Ask your local Toyota dealer for further details be- fore towing.

CAUTION

WEIGHT LIMITS Before towing, make sure the total trail- er weight, gross combination weight, gross vehicle weight, gross axle weight and trailer tongue load are all within the limits. The total trailer weight and tongue load can be measured with platform scales found at a highway weighing station, build- ing supply company, trucking company, junk yard, etc.

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.

’03 4Runner_U (L/O 0305)

TIRES (cid:1) Ensure

that your vehicle’s

tires are properly inflated. See page 332 in Sec- tion 7–2 and page 356 in Section 8 for instructions.

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

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.

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
