CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surrounding
area is clear, to avoid striking other vehicles, objects or people. 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 acci-
dent and result in death or serious injury.
NOTICE
■To avoid damaging the transmission and other components
●Avoid spinning the wheels and depressing the accelerator pedal more than neces-
sary.
●If the vehicle remains stuck even after th ese procedures are performed, the vehicle
may require towing to be freed.
●When a warning message for the automatic transmission fluid temperature is dis-
played while attempting to free a stuck vehicle, immediately remove your foot from
the accelerator pedal and wait until the warning message disappears. Otherwise, the
transmission may become damaged. ( →P. 533)
