To use your accessory inator system, do the
following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if

6. Press the accessory inator switch. The
light in the switch will come on to show
the system is working.
If the accessory inator system does not turn on
or the light does not come on, the fuse may
be blown or installed incorrectly. SeeFuses and
Circuit Breakers on page 497or see your
dealer for service.
Your accessory inator will automatically shut off
after about 10 minutes. The light in the switch
will blink. After about one minute you can use the
system again. Press the switch and the indicator
light will come on.Notice:If you run the accessory inator
longer than 30 minutes at a time, you could
damage the inator. The repairs would not be
covered by your warranty. Run the inator
for short periods of time only.
After running the accessory inator for 30 minutes,
wait at least 10 minutes before restarting the
accessory inator.
To turn off the inator, do the following:
1. Press the switch and detach the hose, rst
from the inated object, then from the outlet.
2. Put the protective cap back on.
3. Place the inator kit tools in the pouch, and

10. Tighten the wheel
nuts rmly in a
crisscross sequence,
as shown.
Notice:Wheel covers will not t on your
compact spare. If you try to put a wheel cover
on the compact spare, you could damage
the cover or the spare.
11. Do not try to put a wheel cover on the
compact spare tire. It will not t. Store
the wheel cover securely in the rear of the
vehicle until you have the at tire repaired or
replaced.Secondary Latch System
Your vehicle may have an underbody-mounted tire
hoist assembly equipped with a secondary latch
system. It is designed to stop a tire from suddenly
falling off your vehicle if the cable holding the
spare tire is damaged. For the secondary latch to
work, the tire must be stowed with the valve
stem pointing down.
Your vehicle uses the underbody tire hoist
assembly to store either the compact spare or a
at road tire. SeeStoring a Flat or Spare Tire and
Tools on page 483for instructions on storing
the spare or at tire correctly.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
481

Storing the Flat or 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.To store the spare tire, do the following:
1. Lay the tire near the rear of the vehicle with
the valve stem down.
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. Slide the cable retainer through the center of
the wheel and start to raise the tire.
Make sure the retainer is fully seated across
the underside of the wheel.
4. When the tire is almost in the stored position,
turn the tire so the valve is towards the rear of
the vehicle.
This will help when you check and maintain
tire pressure in the spare.
5. Raise the tire fully against the underside of
the vehicle. Continue turning the folding
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.
484

6. Make sure the tire is stored securely. Push,
pull (A), and then try to turn (B) the tire. If the
tire moves, use the folding wrench to
tighten the cable.
Storing the Tools
A. Strap
B. Bag and Tools
C. Jack
Put back all tools as they were stored in the jack
storage compartment and put the compartment
cover back on.
485

To replace the cover, line up the tabs on the right
of the cover with the slots in the cover opening.
Push the cover in place and push down the tab so
that it rests in the groove. This secures the
cover in place.
Store the center cap or the plastic bolt-on wheel
covers until a full size tire is put back on the
vehicle. When you replace the compact spare with
a full-size tire, reinstall the bolt-on wheel covers
or the center cap. Hand-tighten them over
the wheel nuts, using the folding wrench.
Compact Spare Tire
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly. It
should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles
(5 000 km), so you can nish your trip and have
the full-size tire repaired or replaced at your
convenience.Of course, it is best to replace the spare with a
full-size tire as soon as possible. The spare tire will
last longer and be in good shape in case it is
needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.

Pressure on page 456. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 470.

highway drivers prior to the Engine Oil Life System
service notication. Check the tires for wear
