1. Remove the compressorfrom its storage location.
See Storing the Tire
Sealant and Compressor
Kit 0451.
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
0108.
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.
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
0427.
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 (Continued)

458 Vehicle Care
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
(if equipped).
Do not use automatic car
washes due to lack of
clearance for the
undercarriage, wide rear
tires, and wheels.
Caution
To avoid damage to a matte
paint finish, do not use an
automatic car wash
equipped with brushes or
scrubbers. Only use
touchless automatic car
washes.
If using an automatic car wash,
follow the car wash
instructions. The windshield
wiper and rear window wiper,
if equipped, must be off.
Remove any accessories that
may be damaged or interfere
with the car wash equipment.
Hand Wash
Rinse the vehicle well, before
and after washing, to remove
all cleaning agents completely.
If they are allowed to dry on
the surface, they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel
to avoid surface scratches
and water spotting. Cleaning Underhood
ComponentsCaution
Do not power wash any
component under the hood
that has this
esymbol.
This could cause damage to
the vehicle that would not
be covered by the vehicle
warranty.
Avoid using solvents or
abrasive cleaners that may
harm underhood components.
GM recommends using only
water to clean underhood
components.
If using a pressure washer,
ensure the following criteria
is met:
.Water pressure must be
kept below 14 000 KPa
(2,000 PSI).
.Water temperature must be
below 80 °C (180 °F).

462 Vehicle Care
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect
brake linings/shoes for wear
or cracks. Inspect all other
brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper attachment,
connections, binding, leaks,
cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges,
and the steel fuel door hinges,
unless the components are
plastic. Applying silicone
grease on weatherstrips with
a clean cloth will make them
last longer, seal better, and
not stick or squeak.
Underbody Maintenance
Every six months, use plain
water to flush any corrosive
materials from the underbody.
Take care to thoroughly clean
any areas where mud and
other debris can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.

Maintenance
Schedule
Tire Rotation and
Required Services Every
12 000 km (7,500 mi)
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for
proper tire inflation pressure,
and check for damaged tires
or wheels. If the unusual wear
continues after the rotation,
check the wheel alignment.
See When It Is Time for New
Tires0437 and
Wheel Replacement 0441.
.Perform Multi-Point Vehicle
Inspection. See Multi-Point
Vehicle Inspection (MPVI)
0474.
.Lubricate body components.
See Exterior Care 0457.
Additional Required
Services —Normal
Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed,
change engine oil and filter,
and reset oil life system. Or
when the CHANGE ENGINE
OIL SOON message displays,
have the engine oil and filter
changed within the next
1 000 km/600 mi. If driven
under the best conditions,
the engine oil life system
may not indicate the need
for vehicle service for up to
a year. The engine oil and
filter must be changed at
least once a year and the oil
life system must be reset.
Your trained dealer
technician can perform this
work. If the engine oil life
system is reset accidentally,
service the vehicle within
5 000 km/3,000 mi since the
last service. Reset the oil life system when the oil is
changed. See Engine Oil Life
System
0386.
.When the REPLACE AT
NEXT OIL CHANGE
message displays, the engine
air filter should be replaced
at the next engine oil
change. When the REPLACE
ENGINE AIR FILTER SOON
message displays, the engine
air filter should be replaced
at the earliest convenience.
Reset the engine air filter life
system after the engine air
filter is replaced. See Engine
Air Filter Life System 0389.
Every 36 000 km (22,500 mi)
.Passenger compartment air
filter replacement (or every
24 months, whichever
occurs first). More frequent
replacement may be needed
if the vehicle is driven in
areas with heavy traffic,
poor air quality, areas with
high dust levels or are
sensitive to environmental
allergens. Filter replacement
