You may have an air inator kit that is located in the
glove compartment. It includes a 22 ft (6.7 m) hose with
three nozzle adapters.
To use the accessory inator, do the following:
1. Attach the appropriate nozzle adapter to the end of
the hose if required.
2. Attach that end of the hose to the object you wish
to inate.
3. Attach the other end of the hose to the outlet.
4. Press and release the switch to turn the air inator
on. The indicator light will remain on when the
inator is running.
The system has an internal clock to prevent
overheating. The system will allow about ve
minutes of running time, then the compressor will
stop. The indicator light will then begin to ash.
When the indicator is off, the inator can be started
again by pressing the switch. If the compressor
is still hot, it may only run for a short time before
shutting off again.
5. Press and release the switch to turn the inator off.Place the inator kit tools in the pouch and store it in its
proper location. Remove the inator hose from the
outlet during loading and unloading. Load leveling will
not function with the inator hose attached to the inator
outlet. See “Electronically Controlled Air Suspension
System” underLoading Your Vehicle on page 4-43.
To reinstall the cover, line up the tabs at the back of the
cover, put it in place and latch the tabs.
A continuous ashing indicator light may also indicate a
malfunction in the air suspension system. See
“Electronically Controlled Air Suspension System” under
Loading Your Vehicle on page 4-43for more information.
{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.

The following instructions explain how to remove the
underbody-mounted spare from underneath your vehicle.
Notice:If you remove or restow a tire from/to the
storage position under the vehicle when it is
supported by a jack, you could damage the tire
and/or your vehicle. Always remove or restow a tire
when the vehicle is on the ground.
1. Insert the socket end of the extension on a
45 degree angle downward into the hoist drive shaft
hole. It is exposed when the rear gate is open
and is just above the rear bumper. Be sure
the socket end of the extension connects to the
hoist shaft.2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until
the spare tire can be pulled out from under the
vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. SeeSecondary Latch System on
page 5-80for more information.
3. Tilt the retainer at the end of the cable when the
tire has been completely lowered, and pull it
through the wheel opening. Pull the tire out from
under the vehicle.

secondary latch system cable has been reinstalled,
you could damage your vehicle. Always reinstall
this cable before driving your vehicle.
