Off- road vehicle precautions

272

’04 4Runner_U (L/O 0409)

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.

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 four 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.

NOTICE

(cid:1) Do not use gasohol other than stated above. It will cause fuel sys- tem damage or vehicle performance problems.

(cid:1) If driveability problems occur (poor hot starting, vaporizing, engine knock, etc.), discontinue the use.

(cid:1) Take care not to spill gasohol dur- ing refueling. Gasohol may cause paint damage.

Fuel pump shut off system The fuel pump shut off system stops sup- plying fuel to the engine to minimize the risk of fuel leakage when the engine stalls or an airbag inflates upon collision. To restart the engine after the fuel pump shut off system activates, ignition switch to “ACC” or “LOCK” once and start it.

Three- way catalytic converters

1GR- FE engine

2UZ- FE engine

276

’04 4Runner_U (L/O 0409)

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:1) Use only unleaded gasoline. (cid:1) 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:1) Do not allow the engine to run at idle speed for more than 20 min- utes.

(cid:1) Avoid racing the engine. (cid:1) Do not push-start or pull-start your

vehicle.

(cid:1) Do not turn off the ignition while

the vehicle is moving.

(cid:1) 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:1) 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:1) 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”.
