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

stuck in mud, dirt, or snow.
Stop the engine. Set the parking brake and shift 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 ot her material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to the D or R position (vehicles with an auto-
matic transmission) or 1 or R position (vehicles with a manual
transmission) and carefully appl y the accelerator to free the
vehicle.
Turn off TRAC and VSC if these functions are hampering your
attempts to free the vehicle. (  P. 2 0 6 )
