Tire Inspection and Rotation
The tires on your vehicle should be inspected regularly
for wear. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 6-63and
Wheel Replacement on page 6-67for additional
information.
If your vehicle has P235/50R18 size tires they should
be rotated any time you notice unusual wear.
When rotating P235/50R18 size tires, always use the
correct rotation pattern shown here.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the tire and loading
information label, seeInation - Tire Pressure on
page 6-58andLoading Your Vehicle on page 5-33.Vehicles that have the Tire Pressure Monitor (TPM)
system will need to have the sensors reset after a tire
rotation is performed. A special tool is needed to reset the
sensor identication codes. See your dealer for service.
Make certain that all wheel nuts are properly tightened.
SeeWheel Replacement on page 6-67and “Wheel Nut
Torque” underCapacities and Specications on
page 6-92.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause a crash. When you change
a wheel, remove any rust or dirt from places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper
towel to do this; but be sure to use a scraper
or wire brush later, if you need to, to get all the
rust or dirt off.

Buying New Tires
GM has developed and matched specic tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Specication
(TPC spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.
GM’s exclusive TPC Spec system considers over a
dozen critical specications that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and tire
pressure monitoring performance. GM’s TPC Spec
number is molded onto the tire’s sidewall by the tire
manufacturer. If the tires have an all-season tread design,
the TPC spec number will be followed by an MS for mud
and snow. SeeTire Sidewall Labeling on page 6-52for
additional information.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W, Y,
and ZR speed rated tires. If you choose snow tires with
a lower speed rating, never exceed the tire’s maximum
speed capability.{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different
sizes (other than those originally installed on
your vehicle), brands, or types (radial and
bias-belted tires), the vehicle may not handle
properly, and you could have a crash. Using
tires of different sizes (other than those
originally installed on your vehicle), brands or
types, may also cause damage to your vehicle.
Be sure to use the correct size, brand, and
type tires on all four wheels.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
6-64

If you must replace your vehicle’s tires with those that
do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias-belted tires) as your
vehicle’s original tires.
Vehicles that have a tire pressure monitoring system
may give an inaccurate low-pressure warning if
non-TPC spec rated tires are installed on your vehicle.
Non-TPC Spec rated tires may give a low-pressure
warning that is higher or lower than the proper
warning level you would get with TPC Spec rated tires.
SeeTire Pressure Monitor System on page 6-59.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information Label. This label
is attached to the vehicle’s center pillar (B-pillar).
SeeLoading Your Vehicle on page 5-33for more
information about the Tire and Loading Information
Label and its location on your vehicle.Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires, this
may affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability,
and resistance to rollover. Additionally, if your vehicle
has electronic systems such as, anti-lock brakes,
traction control, and electronic stability control, the
performance of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable level
of performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use
GM specic wheel and tire systems developed
for your vehicle, and have them properly
installed by a GM certied technician.
SeeBuying New Tires on page 6-64andAccessories
and Modications on page 6-3for additional information.
6-65

If a Tire Goes Flat
It is unusual for a tire to “blow out” while you are
driving, especially if you maintain your tires properly.
If air goes out of a tire, it is much more likely to leak
out slowly. SeeTires on page 6-50for additional
information.
Your vehicle, when new, had run-at tires. This type
of tire can operate effectively with no air pressure,
so you will not need to stop on the side of the road
to change a at tire. You can just keep on driving.
The shorter the distance you drive and the slower the
speed, the greater the chance that the run-at tire
will not have to be replaced. Run-at tires perform
so well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
SeeRun-Flat Tires on page 6-56andTire Pressure
Monitor System on page 6-59.{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, your vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could
lose control of your vehicle. You or others
could be injured. Don’t drive over 55 mph
(90 km/h) when the TIRE FLAT MAX SPD 55,
REDUCED HNDLG message is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If the TPM system detects a tire pressure below
5 psi (34 kPa), the TIRE FLAT MAX SPD 55, REDUCED
HNDLG warning message is displayed on the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 3-64andDIC Warnings and Messages
on page 3-67for information and details about the
DIC operation and displays.
6-75

{CAUTION:
Special tools and procedures are required
to service a run-at tire. If these special tools
and procedures are not used you or others
could be injured and your vehicle could be
damaged. Always be sure the proper tools
and procedures, as described in the service
manual, are used.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
vehicle’s run-at tires. This damage would not
be covered by warranty. Do not use liquid sealants
in your vehicle’s run-at tires.
To order a service manual, seeService Publications
Ordering Information on page 8-14.
If a tire goes at, the stability control system will
turn on automatically even if it was disabled by the
driver. When a at tire condition exists the StabiliTrak
®
system cannot be turned off. SeeStabiliTrak®System
on page 5-11.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if it
is cleaned often. Although not always visible, dust
and dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove
particles from your upholstery. It is important to keep
your upholstery from becoming and remaining heavily
soiled. Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of
heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.

Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do,
it may severely weaken them. In a crash,
they might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather frequent application may be required.
SeeRecommended Fluids and Lubricants on page 7-11.
Washing Your Vehicle
The paint nish on the vehicle provides beauty, depth of
color, gloss retention, and durability.
The best way to preserve the vehicle’s nish is to keep it
clean by washing it often with lukewarm or cold water.
Do not wash the vehicle in the direct rays of the sun.
Use a car washing soap. Do not use strong soaps
or chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. GM-approved
cleaning products can be obtained from your dealer.
SeeVehicle Care/Appearance Materials on page 6-84.
Do not use cleaning agents that are petroleum
based, or that contain acid or abrasives. All cleaning
agents should be ushed promptly and not allowed
to dry on the surface, or they could stain. Dry the nish
with a soft, clean chamois or an all-cotton towel to
avoid surface scratches and water spotting.
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for the wide rear tires and wheels, you
could damage your vehicle. Verify with the manager
of the car wash that your vehicle will t before
entering the car wash or use a touchless car wash.
High pressure car washes may cause water to enter
the vehicle.

®dealer can assist you
with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 7-11.
At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 6-15for further
details.
Notice:It is important to check your oil regularly
and keep it at the proper level. Failure to keep your
engine oil at the proper level can cause damage
to your engine not covered by your warranty.
Engine Coolant Level Check
