Make sure the spare tire and jacking
equipment are stowed and secured in the
proper storage location.
Preparing to Change the Tire
NOTE: To lift your vehicle by other than the
front or rear jacking points, be sure to
use only hoist adapters with a wide
contact surface.
1. Make sure that your vehicle will not move
or roll. Put the gearshift in P (Park). Set the
parking brake and block the wheel that is
diagonally opposite the tire that you are
changing.
NOTE: Make sure the ignition is in the OFF
position.
When one of the back wheels is off the ground,
the transmission alone will not prevent the
vehicle from moving or slipping off the jack,
even if the vehicle is in P (Park). To prevent the
vehicle from moving when you change a tire, be
sure the parking brake is set, then block the
wheel (both directions) that is diagonally
opposite (other side and end of the vehicle) to
the tire being changed.
If the vehicle slips off the jack, you or
someone else could be seriously injured.
