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.

●If the vehicle remains stuck after trying these procedures, the vehicle may require
towing to be freed.

stuck in mud, dirt, or snow.
●Stop the hybrid system. Set the parking brake and put the selec-
tor lever in P.
● 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 hybrid system.
