To 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.
2. Remove the spare tire and jack. See previous section for
instructions on spare tire removal. The jack is located in the rear
storage compartment in the right door panel of the cargo
area. You will have to unfasten the jack before removing it as
shown in the illustration. The jack handle is in the tool kit
located behind the jack.
NOTE: All occupants should be out of the vehicle while it is
on the jack.
