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. See
Tire Sidewall Labeling on page 401for additional
information.
Winter tires with the same speed rating as your
original equipment tires may not be available for H,
V, W 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 of tires on all wheels. It is
all right to drive with your vehicle’s
compact spare temporarily, it was
developed for use on your vehicle. See
Compact Spare Tire on page 442.
{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.

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 410.
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 322,
for 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 speci c wheel and
tire systems developed for your vehicle,
and have them properly installed by a GM
certi ed technician.
SeeBuying New Tires on page 416and
Accessories and Modi cations on page 347for
additional information.

Wood Panels
Use a clean cloth moistened in warm, soapy water
(use mild dish washing soap). Dry the wood
immediately with a clean cloth.
Speaker Covers
Vacuum around a speaker cover gently, so that
the speaker will not be damaged. Clean spots with
just water and mild soap.
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 480.
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. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 452.Donot
use cleaning agents that are petroleum based,
or that contain acid or abrasives.

#Lubricate the front suspension, steering linkage,
transmission shift linkage, and parking brake
cable guides. Control arm ball joints require
lubrication but should not be lubricated unless
their temperature is 10°F (-12°C) or higher, or they
could be damaged.(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, cha ng,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts, signs of wear or lack of lubrication. Inspect
power steering lines and hoses for proper
hook-up, binding, leaks, cracks, cha ng, etc.
