panel by gently prying with a plastic
tool near each clip, beginning at the
point shown.
To install the end cover, insert the
tabs on the back of the cover into the
slots in the instrument panel at the
points shown. Align the clips with the
slots in the instrument panel, and
press the cover into place.
The vehicle may not be equipped with

and cause a crash. Use only
radial-ply tires with the wheels
on the vehicle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H, V,
W, Y and ZR speed rated tires.
Never exceed the winter tires’
maximum speed capability when
using winter tires with a lower
speed rating.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size, load
range, speed rating, and
construction (radial) as the
original tires.
The Tire and Loading Information
label indicates the original
equipment tires on the vehicle.
See Vehicle Load Limits 0228.Different Size Tires and
Wheels
If wheels or tires are installed that are
a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This increases
the chance of a crash and serious
injury. Only use GM specific wheel
and tire systems developed for the
vehicle, and have them properly
installed by a GM certified
technician. See
Buying New Tires 0379 and
Accessories and Modifications 0323.
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in the
United States. The grades are
molded on the sidewalls of most
passenger car tires. The Uniform
Tire Quality Grading (UTQG)
system does not apply to deep
tread, winter tires, compact spare
tires, tires with nominal rim
diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they must

Using the Tire Sealant and
Compressor Kit to Temporarily
Seal and Inflate a
Punctured Tire
When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire faster.
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.
Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant canister (4) and compressor from its storage
location. See Storing the Tire Sealant
and Compressor Kit 0390.
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.
4. Attach the air only hose (10) to thesealant canister inlet valve (1) by
turning it clockwise until tight.
5. Slide the base of the tire sealantcanister (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/air hose (2) tothe tire valve stem by turning it
clockwise until tight.

8. Plug the power plug (9) into theaccessory 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.
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 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.
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.

Washing the Vehicle
To preserve the vehicle finish, wash it
often and out of direct sunlight.
Caution
Do not use petroleum-based, acidic,

product.
Caution
Avoid using high-pressure washes
closer than 30 cm (12 in) to the
surface of the vehicle. Use of power
washers exceeding 8 274 kPa
(1,200 psi) can result in damage or
removal of paint and decals.
Automatic Car Wash
Caution
Automatic car washes can cause
damage to the vehicle, wheels,
ground effects, and convertible top

Do not use automatic car washes
due to lack of clearance for the
undercarriage, wide rear tires, and
wheels.
