lever in P (vehicles with an automatic transmission) or N (vehi-
cles with a manual transmission).

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. 1 8 8 )
