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-

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 (vehi-
cles 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 (automatic) or 1 or R
position (manual) 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 7 2 )
