If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard Warning
Flashers 0131.
See If a Tire Goes Flat 0383 for other
important safety warnings.
1. Remove the compressor from its storage location. See Storing the
Tire Sealant and Compressor Kit
0 390.
2. Remove the air only hose (10) and the power plug (9) from the bottom
of the compressor. 3. Place the compressor on the
ground near the flat tire.
Make sure the tire valve stem is
positioned close to the ground so
the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (10) to the tire valve stem by turning it
clockwise until tight.
6. Plug the power plug (9) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets. See
Power Outlets 086.
Do not pinch the power plug cord
in the door or window.
7. Start the vehicle. The vehicle must be running while using the air
compressor.
8. Press the on/off button (5) to turn the tire sealant and compressor
kit on.
The compressor will inflate the tire
with air only. 9. Inflate the tire to the
recommended inflation pressure
using the pressure gauge (8). The
recommended inflation pressure
can be found on the Tire and
Loading Information label. See Tire
Pressure 0370.
The pressure gauge (8) may read
higher than the actual tire pressure
while the compressor is on. Turn
the compressor off to get an
accurate pressure reading. The
compressor may be turned on/off
until the correct pressure is
reached.
Caution
If the recommended pressure
cannot be reached after
approximately 25 minutes, the
vehicle should not be driven farther.
The tire is too severely damaged
and the tire sealant and compressor
kit cannot inflate the tire. Remove
the power plug from the accessory
power outlet and unscrew the
inflating hose from the tire valve.

394 VEHICLE CARE
Contact a professional towing service
if the disabled vehicle must be
transported. GM recommends a
flatbed tow truck to transport a
disabled vehicle. Use ramps to help
reduce approach angles, if necessary.
If equipped, a tow eye may be located
near the spare tire or emergency jack.
Do not use the tow eye to pull the
vehicle from the snow, mud, sand,
or ditch. Tow eye threads may have
right or left-hand threads. Use caution
when installing or removing the
tow eye.
The vehicle must be in N (Neutral)
and the electric parking brake must be
released when loading the vehicle
onto a flatbed tow truck.
.If the vehicle is equipped with car
wash mode and has 12-volt battery
power, refer to“Car Wash Mode ”
under Automatic Transmission
(Mechanical Shifter) 0242 or
Automatic Transmission (Electronic
Shifter) 0244 to place the vehicle in
N (Neutral).
.If the 12-volt battery is dead and/or
the engine will not start, the vehicle
will not move. Try to jump start the
vehicle. Refer to Jump Starting -
North America 0390 and if the
jump start is successful, retry the
“Car Wash Mode ”procedure.
.If jump starting is unsuccessful, the
vehicle will not move. Tire skates or
dollies must be used under the
non-rolling tires to prevent vehicle
damage.
V-Series Blackwing Only
Due to low ramp angles on the
V-Series Blackwing, use care when
loading the vehicle onto a flatbed carrier. Front spring spacers were
provided for lifting the front
suspension if more clearance is
necessary when towing.
Front Tow Eye
The vehicle is equipped with a tow
eye. Only use the tow eye to pull the
vehicle onto a flatbed car carrier from
a flat road surface. Do not use the tow
eye to pull the vehicle from snow,
mud, or sand. The tow eye is located
under the carpet in the trunk.
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.

Front Tow Eye
Caution
Improper use of the tow eye can
damage the vehicle. If equipped, use
the tow eye to load a disabled
vehicle onto a flatbed tow truck
from a flat road surface, or to move
the vehicle a short distance. Use
caution and low speeds. The
transmission must be
in (N) Neutral when moving the
vehicle.
The vehicle is equipped with a tow
eye. Only use the tow eye to pull the
vehicle onto a flatbed car carrier from a flat road surface. Do not use the tow
eye to pull the vehicle from snow,
mud, or sand. The tow eye is located
under the carpet in the trunk.
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.
Install the tow eye into the socket and
turn it until it is fully tightened. When
the tow eye is removed, reinstall the
cover with the notch in the original
position.
