Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class “S” type chains
that are the proper size for your tires. Install them
on the front tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.
Accessory Inator
Your vehicle may have an accessory inator. With it,
you can inate things like air mattresses and
basketballs, and you can also use it to bring your tires
up to the proper pressure.
The accessory inator is located in the rear
compartment on the driver’s side. To remove the
protective cap, pull the tab on the cap.
This symbol is on the
accessory inator switch.
There may be an accessory inator kit stored in the
glove box. It includes a 20-foot (6 m) hose with an air
pressure gage and nozzle adapters.
5-66

{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
To use your accessory inator, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to inate.
4. Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6. Press the accessory inator switch. The light in the
switch will come on to show the system is working.
If the accessory inator 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 5-92or 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.
To put the cap back on, line up the tabs at the back
of the cover and put it in place. Push down the
tab to secure the cap.
3. Place the inator kit tools in the pouch, and store in
the glove box.

{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-99for wheel nut
torque specication.
Notice:Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
specication. SeeCapacities and Specifications on
page 5-99for the wheel nut torque specication.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. Store the wheel cover securely in the rear of
the vehicle until you have the at tire repaired
or replaced.
Do not try to put a wheel cover on the compact
spare tire. It will not t.

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.
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.
7. Put back all tools as they were stored in the jack
storage compartment and put the compartment
cover back on.
To put the cover back on, 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.
