inlet valve (1) by turning it
clockwise until tight.
5. Slide the base of the tiresealant canister (3) into
the slot on the top of the
compressor (6) to hold it
upright.
Make sure the tire valve
stem is positioned close to
the ground so the hose will
reach it. 6. Remove the valve stem
cap from the flat tire by
turning it
counterclockwise.7. Attach the sealant/airhose (2) to the tire valve
stem by turning it

442 Vehicle Care
If the vehicle has an
accessory power outlet, do
not use the cigarette
lighter.
If the vehicle only has a
cigarette lighter, use the
cigarette lighter.
Do not pinch the power
plug cord in the door or
window.
9. Start the vehicle. The vehicle must be running
while using the air
compressor.
10. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into
the tire.
The pressure gauge (8) will
initially show a high
pressure while the
compressor pushes the
sealant into the tire. Once
the sealant is completely
dispersed into the tire, the
pressure will quickly drop and start to rise again as
the tire inflates with
air only.
11. 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 0422.
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 (Continued)
Caution (Continued)
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. See Roadside
Assistance Program 0487.
12. Press the on/off button (5) to turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air
until the vehicle is driven
and the sealant is
distributed in the tire.
Therefore, Steps 13–
21 must be done
immediately after Step 12.
Be careful while handling
the tire sealant and
compressor kit as it could
be warm after usage.

13. Unplug the power plug (9)from the accessory power
outlet in the vehicle.
14. Turn the sealant/air hose (2) counterclockwise
to remove it from the tire
valve stem.
15. Replace the tire valve stem cap.
16. Remove the tire sealant canister (4) from the slot
on top of the
compressor (6).
17. Turn the air only hose (10) counterclockwise to
remove it from the tire
sealant canister inlet
valve (1).
18. Turn the sealant/air hose (2) clockwise onto the
sealant canister inlet
valve (1) to prevent sealant
leakage.
19. Return the air only hose (10) and power plug (9)
back to their original
storage location.
20. If the flat tire was able toinflate to the
recommended inflation
pressure, remove the
maximum speed label from
the sealant canister and
place it in a highly visible
location.
Do not exceed the speed
on this label until the
damaged tire is repaired or
replaced.
21. Return the equipment to its original storage location
in the vehicle.
22. Immediately drive the vehicle 8 km (5 mi) to
distribute the sealant in
the tire. 23. Stop at a safe location and
check the tire pressure.
Refer to Steps 1–10 under
“Using the Tire Sealant and
Compressor Kit without
Sealant to Inflate a Tire
(Not Punctured).”
If the tire pressure has
fallen more than 68 kPa
(10 psi) below the
recommended inflation
pressure, stop driving the
vehicle. The tire is too
severely damaged and the
tire sealant cannot seal the
tire. See Roadside
Assistance Program 0487.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the
recommended inflation
pressure, inflate the tire to
the recommended inflation
pressure.

After starting the disabled
vehicle and removing the
jumper cables, allow it to idle
for several minutes.
Towing the
Vehicle
Transporting a
Disabled Vehicle
(Electronic Shifter)
Caution
Incorrectly transporting a
disabled vehicle may cause
damage to the vehicle. Use
proper tire straps to secure
the vehicle to the flatbed
tow truck. Do not strap or
hook to any frame,
underbody, or suspension
component not specified
below. Do not move vehicles
with drive axle tires on the
ground. Damage is not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with an electric parking
brake and/or an electronic
shifter. In the event of a loss
of 12-volt battery power, the
electric parking brake
cannot be released, and the
vehicle cannot be shifted to
N (Neutral). Tire skates or
dollies must be used under
the non-rolling tires to
prevent damage while
loading/unloading the
vehicle. Dragging the vehicle
will cause damage not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is
not covered by the vehicle
warranty. If equipped, use(Continued)
Caution (Continued)
the tow eye to load the
vehicle onto a flatbed tow
truck from a flat road
surface, or to move the
vehicle a very short distance
at a walking pace. The tow
eye is not designed for
off-road recovery. The
vehicle must be in
N (Neutral) with the electric
parking brake released when
using the tow eye.
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

Vehicle Care 451
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) 0272 or
Automatic Transmission
(Electronic Shifter) 0275 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
0 447 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.
