Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 7‑55.
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
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/
retailer or a qualified technician service them.
The vehicle may have HID headlamps. After an HID
headlamp bulb has been replaced, you may notice that
the beam is a slightly different shade than it was
originally. This is normal.
Taillamps, Turn Signal, Sidemarker,
Stoplamps and Back-up Lamps
To replace one of these bulbs:
A. Stoplamp/Turn Signal/Taillamp
B. Stoplamp/Turn Signal/Taillamp
C. Back-up Lamp
D. Sidemarker Lamp
1. Open the tailgate. See Tailgate
on page 3‑21for
more information.

Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
See Changing a Flat Tire
on page 7‑79for more
information.
Used Replacement Wheels
{WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how far
it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel, use
a new GM original equipment wheel.
Tire Chains
{WARNING:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle without
the proper amount of clearance can cause
damage to the brakes, suspension, or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of the
vehicle and you or others may be injured in a
crash. Use another type of traction device only if
its manufacturer recommends it for use on the
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to the vehicle,
drive slowly, re‐adjust or remove the device if it is
contacting the vehicle, and do not spin the
wheels. If you do find traction devices that will fit,
install them on the rear tires.
