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
With automatic transmission vehicles, 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 put the selector 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 trac-
tion under the tires.
●Restart the engine.
●Turn the traction control OFF. ( P. 1 5 0 )
●Carefully apply the accelerator to free the vehicle.
