5-2. Steps to take in an emergency
If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the surround-
ing 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.
■When shifting the shift lever
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.
NOTICE
■To avoid damaging the transmission and other components
●Avoid spinning the wheels and do not rev the engine.
●If the vehicle remains stuck after trying these procedures, the vehicle may require
towing to be freed.
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 shift the shift lever
to P.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some ot her material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to the D or R position and carefully apply
the accelerator to free the vehicle.
Turn off TRAC and VSC if these functions are hampering your
attempts to free the vehicle. (  P. 1 6 8 )

Vehicle specifications
■Temperature A, B, C
The temperature grades are A (the hi ghest), 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 fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Mo tor 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 excess ive loading, either separately or in
combination, can cause heat build up and possible tire failure.
