Tire Change Procedure
WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission selector lever is in
position P.
WARNING: To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission selector lever in
position P, set the parking brake and block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
WARNING: Never get underneath a vehicle that is supported
only by a jack. If the vehicle slips off the jack, you or someone
else could be seriously injured.
WARNING: Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to avoid
the danger of being hit when operating the jack or changing the wheel.
