5-2. Steps to take in an emergency

n Overheating

If you observe the following, your vehicle may be overheating. l The engine coolant temperature gauge enters the red zone or a loss of

power is experienced.

l Steam is coming from under the hood.

CAUTION

n To prevent an accident or injury when inspecting under the hood of

your vehicle

If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine compartment may be very hot, caus- ing serious injury such as burns.

l Keep hands and clothing away from the fan and other belts while the

engine is running.

l Do not loosen the radiator cap while the engine and radiator are hot.

Serious injury, such as burns, may result from hot coolant and steam released under pressure.

NOTICE

n When adding engine coolant

Wait until the engine has cooled down before adding engine coolant. When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly can cause damage to the engine.

5-2. Steps to take in an emergency If the vehicle becomes stuck

Carry out the following procedures if the tires spin or the vehicle becomes stuck in mud, dirt, or snow.

Stop the engine. Set the parking brake and put the shift lever in P (vehicles with an automatic transmission) or N (vehicles with a manual transmission). Remove the mud, snow, or sand from around the stuck tire. Place wood, stones or some other material to help provide traction under the tires. Restart the engine. Turn off the VSC (→P. 186) Shift the shift lever to D or R (automatic transmission) or 1
or R (manual transmission) and carefully apply the acceler- ator to free the vehicle.

CAUTION

n When attempting to free a stuck vehicle

If you choose to rock the vehicle back and forth to free it, make sure the sur- rounding area is clear, to avoid striking other vehicles, objects or persons. The vehicle may also lunge forward or lunge back suddenly as it becomes free. Use extreme caution.

n When shifting the shift lever

Vehicles with an automatic transmission: Be careful not to shift the shift lever with the accelerator pedal depressed. This may lead to unexpected rapid acceleration of the vehicle that may cause an accident and result in death or serious injury.

6-1. Specifications Fuel information

Your vehicle must use only unleaded gasoline. Unleaded gasoline with an Octane Rating of 87 (Research Octane Number 91) or higher required for optimum engine performance. At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

n Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your Toyota has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

n If your engine knocks

l Consult your Toyota dealer. l You may occasionally notice light knocking for a short time while accelerating or driving uphill. This is normal and there is no need for concern.

n Gasoline quality

In very few cases, driveability problems may be caused by the brand of gasoline you are using. If driveability problems persist, try changing the brand of gasoline. If this does not correct the problem, consult your Toyota dealer.

n Gasoline quality standards

l Automotive manufacturers in the US, Europe and Japan have developed a specification for fuel quality called World-Wide Fuel Charter (WWFC) that is expected to be applied worldwide.

l The WWFC consists of four categories that are based on required

emission levels. In the US, category 4 has been adopted.

l The WWFC improves air quality by lowering emissions in vehicle fleets,

and customer satisfaction through better performance.

n Toyota recommends the use of gasoline containing detergent additives l Toyota recommends the use of gasoline that contains detergent additives

to avoid build-up of engine deposits.

l All gasoline sold in the US contains detergent additives to clean and/or

keep clean intake systems.

n Toyota recommends the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxygenates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas. Toyota recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions and improve air quality.

n Toyota does not recommend blended gasoline

l Toyota allows the use of oxygenate blended gasoline where the

oxygenate content is up to 10% ethanol or 15% MTBE. If you use gasohol in your Toyota, be sure that it has an octane rating no lower than 87.

l Toyota does not recommend the use of gasoline containing methanol.

n Toyota does not recommend gasoline containing MMT

Some gasoline contains octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl). Toyota does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected. The malfunction indicator lamp on the instrument cluster may come on. If this happens, contact your Toyota dealer for service.

NOTICE

n Notice on gasoline quality

l Do not use leaded gasoline.

Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters causing the emission control system to malfunction.

l Do not use gasohol other than that stated here.

Other gasohol may cause fuel system damage or vehicle performance problems.

l Use of unleaded gasoline with an Octane rating lower than 87 may result

in engine knocking. Persistent knocking can lead to engine damage.

n Fuel-related poor driveability

If after using a different type of fuel, poor driveability is encountered (poor hot starting, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.

n When refueling with gasohol Take care not to spill gasohol. It can damage your vehicle’s paint.

Uniform tire quality grading

This information has been prepared in accordance with regulations issued by the National Highway Traffic Safety Administration of the U.S.A. Department of Transportation. It provides the purchasers and/or prospective purchasers of Toyota vehicles with information on uniform tire quality grading.

Your Toyota dealer will help answer any questions you may have as you read this information.

n DOT quality grades

All passenger vehicle tires must conform to Federal Safety Requirements in addition to these grades. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A

n Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, 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 habits, service practices and differences in road characteristics and climate.

n 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 pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.

n Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing the tire’s resistance 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 corresponds 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 performance 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 overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
