Roadside Emergencies
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.
1. Park on a level surface, activate
hazard flashers and set parking
brake.
2. Place gearshift lever in P (Park),
turn engine OFF and block the
diagonally opposite wheel.
3. Remove the spare tire and the
jack. The jack is located in the trunk
(in a holder bracket), on the
right-hand side, next to the wheel
well.
