To store the flat tire:
1. Remove the cable package. The
cable is stored in a plastic bag
under the compact spare tire.
2. Remove the small center cap by
tapping the back of the cap with
the extension of the shaft, if the
vehicle has aluminum wheels.
3. Put the flat tire in the rear
storage area with the valve stem
pointing toward the rear of the
vehicle.
4. Pull the cable (1) through the
door striker (4) then the center of
the wheel (3).
5. Hook the cable onto the outside
portion of the liftgate hinges (2).
6. Hook the other end of the cable
onto the outside portion of the
liftgate hinge on the other side of
the vehicle.
7. Pull on the cable to make sure it
is secure.
8. Make sure the metal tube is
centered at the striker. Push the
tube toward the front of the
vehicle.
9. Close the liftgate and make sure
it is latched properly.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
