Bulb Replacement
For the proper type of replacement bulbs,
seeReplacement Bulbs on page 374.
For any bulb changing procedure not listed
in this section, contact your dealer.
High Intensity Discharge (HID)
Lighting
{CAUTION:
The low beam high intensity discharge
lighting system operates at a very high
voltage. If you try to service any of
the system components, you could be
seriously injured. Have your dealer or
a qualied technician service them.
Your vehicle has HID headlamps. After your
vehicle’s HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.

Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas
inside and can burst if you drop or
scratch the bulb. You or others could
be injured. Be sure to read and follow
the instructions on the bulb package.

Windshield Replacement
Keep in mind that your windshield is part of the
Head-Up Display (HUD) system. If you ever have
to get your windshield replaced, be sure to get
one that is designed for HUD or your HUD image
may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
on page 433for more information.
Replacement blades come in different types and
are removed in different ways. For the proper type
and length, seeNormal Maintenance Replacement
Parts on page 445.It is a good idea to clean or replace the wiper
blade assembly every six months.
Allowing the wiper blade arm to touch the
windshield when no wiper blade is installed
could damage the windshield. Any damage that
occurs would not be covered by your warranty.
Do not allow the wiper blade arm to touch
the windshield.
To remove the wiper blade assembly,
do the following:
1. Open the hood to gain access to
the windshield wipers.
2. Lift the wiper arm away from the
windshield.

claws of the blade assembly. At the notch
end, pull the insert from the blade assembly.
To install the new wiper insert:
1. Slide the insert (D), notched end last, into the
end with the two blade claws (A). Slide the
insert all the way through the blade claws at
the opposite end (B). Plastic caps (C) will
be forced off as the insert is fully installed.

2. Be sure the notches are locked by the
bottom claws. Make sure that all other claws
are properly locked on both sides of the
insert slots.
3. Put the blade assembly pivot in the wiper arm
hook. Pull up until the pivot locking tab locks
in the hook slot.
4. Carefully lower the wiper arm and blade
assembly onto the windshield.Installation guide:

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your GM Warranty booklet for
details. For additional information refer to the tire
manufacturer’s booklet included with your vehicle.
{CAUTION:
Poorly maintained and improperly
used tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out
and a serious accident. SeeLoading
Your Vehicle on page 309.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your tires are cold. SeeInflation - Tire
Pressure on page 386.
Overinated tires are more likely to
be cut, punctured, or broken by a
sudden impact — such as when
you hit a pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if
your tires have been damaged,
replace them.
SeeHigh-Speed Operation on page 388
for ination pressure adjustment for
high speed driving.
378

Low-Prole Performance Tire
The original equipment tires on your vehicle are
classied as low-prole performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. You may also notice more
road noise with low-prole tires and that they
tend to wear faster.
Notice:If your vehicle has low-prole tires,
they are more susceptible to damage from
road hazards or curb impact than standard
prole tires. Tire and/or wheel assembly
damage can occur when coming into contact
with road hazards like, potholes, or sharp
edged objects, or when sliding into a curb.
Your GM warranty does not cover this type
of damage. Keep tires set to the correct
ination pressure and, when possible avoid
contact with curbs, potholes, and other
road hazards.
Winter Tires
If you expect to drive on snow or ice covered
roads often, you may want to get winter tires
for your vehicle. All season tires provide good
overall performance on most surfaces butthey may not offer the traction you would like
or the same level of performance as winter tires
on snow or ice covered roads.
Winter tires, in general, are designed for increased
traction on snow and ice covered roads. With winter
tires, there may be decreased dry road traction,
increased road noise, and shorter tread life. After
switching to winter tires, be alert for changes in
vehicle handling and braking.
See your dealer for details regarding winter tire
availability and proper tire selection. Also, see
Buying New Tires on page 394.
If you choose to use winter tires:
Use tires of the same brand and tread type
on all four wheel positions.
Use only radial ply tires of the same size,
load range, and speed rating as the original
equipment tires.
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
winter tires with a lower speed rating, never
exceed the tire’s maximum speed capability.
379

Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The example below shows a typical
passenger (p-metric) tire sidewall.(A) Tire Size:The tire size is a combination of
letters and numbers used to dene a particular
tire’s width, height, aspect ratio, construction
type, and service description. See the “Tire Size”
illustration later in this section for more detail.
(B) TPC Spec (Tire Performance Criteria
Specication):Original equipment tires designed
to GM’s specic tire performance criteria have
a TPC specication code molded onto the sidewall.
GM’s TPC specications meet or exceed all
federal safety guidelines.
(C) DOT (Department of Transportation):
The Department of Transportation (DOT) code
indicates that the tire is in compliance with the
U.S. Department of Transportation Motor Vehicle
Safety Standards.
(D) Tire Identication Number (TIN):The letters
and numbers following DOT code are the Tire
Identication Number (TIN). The TIN shows
the manufacturer and plant code, tire size, and
date the tire was manufactured. The TIN is
molded onto both sides of the tire, although only
one side may have the date of manufacture.
(E) Tire Ply Material:The type of cord and number
of plies in the sidewall and under the tread.
