Storing a Flat or Spare Tire
and Tools
Storing the Spare Tire
{CAUTION:
The underbody-mounted spare tire needs
to be stored with the valve stem pointing
down. If the spare tire is stored with the
valve stem pointing upwards, its
secondary latch will not work properly
and the spare tire could loosen and
suddenly fall from your vehicle. If this
happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of
course, damage to itself as well. Be sure
the underbody-mounted spare tire is
stored with its valve stem pointing down.
{CAUTION:
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.
To store the spare tire:
1. Lay the compact spare tire near the rear of
the vehicle with the valve stem down.
2. Reinstall the plastic spare tire heat shield on
the compact spare tire.
3. If the vehicle has aluminum wheels, remove
the small center cap by tapping the back of
the cap with the extension of the shaft.
472

4. Slide the cable retainer through the center of
the wheel and start to raise the compact
spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
5. When the compact spare tire is almost in the
stored position, turn the tire so the valve is
toward the rear of the vehicle.
This position helps when checking the air
pressure in the compact spare tire.
6. Raise the tire fully against the underside of
the vehicle. Continue turning the lug wrench
until you feel more than two clicks. This
indicates that the compact spare tire is secure
and the cable is tight. The spare tire hoist
cannot be overtightened.
7. Make sure the tire is stored securely. Push,
pull (A), and then try to turn (B) the tire. If the
tire moves, use the lug wrench to tighten
the cable.

Storing the Flat Tire
Notice:Storing the full-size at tire in the
underbody hoist system can expose it to heat
from the exhaust system. This can damage
the tire and underbody hoist system. Do not
store the full-size at tire in the underbody
hoist system.
1. Remove the cable package from the jack
storage area.
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 at tire in the rear storage area with
the valve stem pointing toward the rear of the
vehicle.4. Hook on end of the cable onto the outside
portion of the liftgate hinge opposite (B).
5. Pull the cable (A) through the door striker (E),
the center of the wheel (D), and the plastic
spare tire heat shield (C), as shown.
