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 vehicle is in P (Park) (automatic
transmission) or R (Reverse) (manual transmission).
WARNING: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.
WARNING: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.

Stowing the flat/spare tire and jack
1. Put the flat tire, jack and lug wrench away. Make sure the jack kit is
secured in its original location and orientation in the jack kit recess
under the flat/spare tire. Unblock the wheels.
Note:If you are stowing a flat 22 inch tire and wheel assembly,
temporarily remove the load floor, plastic stowage bins (if equipped), and
the foam load floor supports to make space. Place the 22 inch tire &
wheel assembly in the spare tire well with the valve stem facing down.
Rotate the tire until the jack assembly is able to protrude through a
wheel opening. Replace the plastic stowage bins (if equipped) and foam
load floor supports around the 22 inch tire and wheel assembly.
Note:If you are stowing a flat tire, place the tire in the spare tire well
with the valve stem facing down. Rotate the tire until the jack assembly
is able to protrude through a wheel opening.
Note:If you are stowing the spare tire, place the spare in the spare tire
well in its original position.
2. Secure the wheel by replacing the washer and the wing nut and
turning the wing nut clockwise.
