Tire change procedure
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block (in both directions)
the wheel 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.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension switch prior to jacking, hoisting or towing your
vehicle.
If your vehicle is equipped with air suspension, refer to Air suspension
(if equipped) in the Driving chapter for instructions on how to turn the
system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
