Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and should
need no further adjustment.
If the vehicle is damaged in a crash, the
headlamp aim may be affected.
If adjustment to the headlamps is necessary,
see your dealer.
Bulb Replacement
LED Lighting
This vehicle has all LED lamps. For
replacement of any LED lighting assembly,
contact your dealer.
Electrical System
Electrical System Overload
The vehicle has fuses to protect against an
electrical system overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses protect the wires that provide the
power to the devices in your vehicle.
If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible.

Vehicle Care 265
To check a fuse, look at the band inside the
fuse. If the band is broken or melted,
replace the fuse. Be sure to replace a bad
fuse with a fuse of the identical size and
rating.
Replacing a Blown Fuse
At the next opportunity, see your dealer to
replace the blown fuse.
Headlamp Wiring
An electrical overload may cause the lamps
to go on and off, or in some cases to
remain off. Have the headlamp wiring
checked right away if the lamps go on and
off or remain off.
Windshield Wipers
If the wiper motor overheats due to heavy
snow or ice, the windshield wipers will stop
until the motor cools and will then restart.
Although the circuit is protected from
electrical overload, overload due to heavy
snow or ice may cause wiper linkage
damage. Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an electrical
problem and not snow or ice, be sure to get
it fixed.

{Warning
Using the wrong wheel studs can cause
wheel nuts to not engage the stud
threads and/or wheel. The wheel could
come off and cause personal injury
and/or death. Carbon fiber wheels require
a longer stud than aluminum wheels due
to a thicker hub. When changing the
wheel type between aluminum and
carbon fiber, the studs must match the
wheel type. Incorrect studs will not have
the correct thread engagement. Use the
correct wheel studs for your wheel
assembly.
{Warning
Installing wheel nuts on carbon fiber
wheels when temperatures are below
freezing can result in a damaged
assembly. Once temperatures rise, the
wheel nut removal torque can be very
high making it difficult to remove wheels
nuts. This can result in damaged wheel
nuts and/or wheel nut inserts. Use of
damaged parts could cause the wheel to(Continued)
Warning (Continued)
come off and cause personal injury,
and/or death. Do not install wheel nuts
when temperatures are below freezing.
{Warning
Using the wrong replacement wheels,
wheel bolts, or wheel nuts can be
dangerous. It could affect the braking and
handling of the vehicle. Tires can lose air
and cause loss of control, resulting in a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a used one is
dangerous. How it has been used or how
far it has been driven may be unknown.
It could fail suddenly and cause a crash.
When replacing wheels, use a new GM
original equipment wheel.
Caution
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.
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 loss of control and a crash.
Use another type of traction device only
if its manufacturer recommends it for the
vehicle's tire size combination and road
conditions. Follow that manufacturer's
instructions. To avoid vehicle damage,
drive slowly and readjust or remove the
traction device if it contacts the vehicle.(Continued)
