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.

D Even if the power assist

is com- pletely the brakes will still work. But you will have to push the pedal hard, much harder than nor- mal. And your braking distance will increase.

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).

D Driving with tire chains installed. D Driving over the steps such as the

joints on the road.

D 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.

in a

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: D 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.

D At the end of the anti−lock brake sys- the brake pedal may

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: D Driving on rough, gravel or snow−

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 147 in Sec- tion 1−6.

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: D 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.

D 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 type Your vehicle has a drum−in−disc 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. 338

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.

Theft prevention labels (except for Canada) Your new vehicle carries theft preven- tion labels which are approximately 47
mm (1.85 in.) by 12 mm (0.47 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.

Treadwear—The treadwear grade is a comparative rating based on the wear rate of the tire when tested un- der controlled conditions on a speci- fied government test course. For ex- ample, a tire graded 150 would wear one and a half (1−1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving hab- its, service practices and differences in road characteristics and climate.

Traction AA, A, B, C—The traction grades, from highest to lowest, are AA, A, B, and C, and they represent the tire’s ability to stop on wet pave- ment as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor trac- tion performance. Warning: The traction grade assigned to tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.

—Uniform tire quality grading This information has been prepared in accordance with regulations issued by the National Highway Traffic Safe- ty Administration of the U.S. Depart- ment of Transportation. It provides the purchasers and/or prospective purchasers of Toyota vehicles with in- formation on uniform tire quality grad- ing. Your Toyota dealer will help answer any questions you may have as you read this information. DOT quality grades—All passenger vehicle tires must conform to Fed- eral Safety Requirements in addi- tion these grades. Quality grades can be found where appli- cable on the tire sidewall between tread shoulder and maximum sec- tion width. For example: Treadwear 200 Traction AA Temperature A

to

345

’06 4Runner_U (L/O 0508)

Temperature A, B, C—The tempera- ture grades are A (the highest), B, and C, representing the tire’s resis- tance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C cor- responds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No.109. Grades B and A represent higher levels of per- formance on the laboratory test wheel than the minimum required by law. Warning: The temperature grades for this tire are established for a tire that is properly inflated and not over- loaded. Excessive speed, underinfla- tion, or excessive loading, either sep- arately or in combination, can cause heat buildup and possible tire failure.

Cargo and luggage— —Stowage precautions When stowing cargo and luggage in the vehicle, observe the following: D Put cargo and luggage in the lug- gage compartment when at all possible. Be sure all items are se- cured in place.

D Be careful to keep the vehicle bal- anced. Locating the weight as far forward as possible helps maintain balance.

D For better fuel economy, do not

carry unneeded weight.

CAUTION

D To prevent cargo and luggage from sliding forward during braking, do not stack anything in the luggage compartment higher the seatbacks. Keep cargo and luggage low, as close to the floor as pos- sible.

than

D Do not store more than 91 kg (200 lb.) of cargo and luggage in the luggage compartment. If the third seats are occupied, do not store cargo and luggage in the luggage compartment. D Do not place anything on the flattened seat or it may slide forward during braking.

D Never allow anyone to ride in the luggage compartment. It is not designed for passengers. They should ride in their seats with their seat belts properly fastened. Otherwise, they are much more likely to suffer seri- ous bodily injury, in the event of sudden braking or a colli- sion.

351

’06 4Runner_U (L/O 0508)

FOR

—Capacity and distribution Cargo capacity depends on the to- tal weight of the occupants. (Cargo capacity) = (Total load capac- ity) – (Total weight of occupants) STEPS CORRECT LOAD LIMIT 1. Locate the statement “The com- bined weight of occupants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

DETERMINING

3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.

4. The resulting figure equals the available amount of cargo and lug- gage load capacity. For example, if the “XXX” amount equals 1400
lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and lug- gage load capacity is 650 lbs. (1400–750 (5x150)=650 lbs).

5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available car- go and luggage load capacity of your vehicle.

For details about trailer towing, see page 362.

D Do not place anything on the luggage cover. Such items may be thrown about and possibly injure people in the vehicle during sudden braking or an accident. Secure all items in a safe place.

D 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 turning, and im- pair the driver’s control of the vehicle. In an accident they may injure the vehicle occu- pants.

352

’06 4Runner_U (L/O 0508)

CAUTION

Even if the total load of occu- pant’s weight and the cargo load is less than the total load capac- ity, do not apply the load uneven- ly. That may cause not only dam- age to the tire but also deteriora- tion to the steering ability due to unbalance of the vehicle, causing an accident.

From this condition, if 3 more passen- gers with the combined weight of 176
kg (388 lb.) get on, the available car- go and luggage load will be reduced as follows:

With 5 occupants:

265 kg – 176 kg = 89 kg. (584 lb. – 388 lb. = 196 lb.)

With 7 occupants:

310 kg – 176 kg = 134 kg. (683 lb. – 388 lb. = 295 lb.)

As shown in the above example, if the number of occupants increases, the cargo and luggage load equaling the combined weight of occupants who got on later must be reduced. In other words, if the increase in the number of occupants causes the excess of the total load capacity (combined weight of occupants plus cargo and luggage load), you have to reduce the cargo and luggage on your vehicle. For details about total load capacity, see “Vehicle load limits” on page 350.

Total load capacity

EXAMPLE ON YOUR VEHICLE In case that 2 people with the com- bined weight of 166 kg (366 lb.) are riding in your vehicle with the total load capacity of 431 kg (950 lb.), the available amount of cargo and lug- gage load capacity will be as follows:

With 5 occupants:

431 kg – 166 kg = 265 kg. (950 lb. – 366 lb. = 584 lb.)

With 7 occupants:

476 kg – 166 kg = 310 kg. (1050 lb. – 366 lb. = 684 lb.)

Types of tires Determine what kind of tires your vehicle is originally equipped with. 1. Summer tires Summer tires are high−speed capabil- ity tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow−covered or icy roads. For driving on snow−covered or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires All season tires are designed to pro- vide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round.

traction

All season tires, however, do not have adequate performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving. The details about how to distinguish summer tires from all season tires are described on page 342.

CAUTION

D Do not mix summer and all sea- son tires on your vehicle as this can cause dangerous han- dling characteristics, resulting in loss of control.

D Do not use tire other than the manufacturer’s designated tires, and never mix tires or wheels of the sizes different from the originals.

NOTICE

z Do not race a cold engine. z If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.

Tips for driving in various conditions D Always slow down in gusty crosswinds. This will allow you much better control. D Drive slowly onto curbs and, if pos- sible, at a right angle. Avoid driving onto high, sharp−edged objects and other road hazards. Failure to do so can lead to severe tire damage such as a tire burst. Drive slowly when passing over bumps or travelling on a bumpy road. Other- wise, the impact could cause severe damage to the tires and/or wheels.

D When parking on a hill, turn the front wheels until touch the curb so that the vehicle will not roll. Apply the parking brake, and place the transmis- sion the wheels.

If necessary, block

in “P”.

D Washing your vehicle or driving through deep water may get the brakes wet. To see whether they are wet, check that there is no traffic near you, and then press the pedal lightly. If you do not feel a normal braking force, the brakes are probably wet. To dry them, drive the vehicle cautiously while lightly pressing the brake pedal with the park- ing brake applied. If they still do not work safely, pull to the side of the road and call a Toyota dealer for assistance.

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. D State and Local Parks and Recreation

Departments

D State Motor Vehicle Bureau

D Recreational Vehicle Clubs D 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: D Drive carefully when off the road. Do not take unnecessary risks by driving in dangerous places.

D 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.

D Always check your brakes for effec- tiveness immediately after driving in sand, mud, water or snow.

D 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.

D 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

D 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.

359

’06 4Runner_U (L/O 0508)

z 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. Only use “Toyota Super Long Life Coolant” or similar high quality ethylene glycol based non−silicate, non−amine, non−nitrite, and non−borate coolant with long−life hy- brid organic acid technology. (Coolant with long−life hybrid organic acid technology is a combination of low phosphates and or- ganic acids.) See “Checking the engine coolant level” on page 422 in Section 7−2 for details of coolant type selection. For the U.S.A.—“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. This coolant pro- vides protection down to about −35_C (−31_F). For the Canada—“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. This coolant pro- vides protection down to about −42_C (−44_F).

NOTICE

Do not use plain water alone.

NOTICE

z 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.

z 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 transmission and transfer case, reducing the gear oil’s lubricating qualities.

Dinghy towing

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 starting. Section 7−3 tells you how to visually in- spect the battery. Your Toyota dealer and most service stations will be pleased to check the level of charge. Make sure the engine oil viscosity is suitable for the cold weather. See page 420 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—they 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

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

D Never tap

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

D 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.

’06 4Runner_U (L/O 0508)

TIRES D Ensure

that your vehicle’s

tires are properly inflated. See page 425 in Sec- tion 7−2 and page 451 in Section 8 for instructions.

D 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.

367

’06 4Runner_U (L/O 0508)

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. The towing connector can be also con- nected 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 bearing, etc.) for the first 800 km (500 miles) of driving.

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 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.

reduce speed

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 befo- re changing lanes.

D In order to maintain engine braking effi- ciency, do not put the transmission in “D”.
