When the System Does Not Seem To
Work Properly
The rear vision camera system may not work properly
or display a clear image in the following situations:
In the dark.
When the sun or the beam of headlights is shining
directly into the camera lens.
If ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
If the back of the vehicle is in an accident, the
position and mounting angle of the camera
may change or the camera may be affected. Be
sure to have the camera and its position and
mounting angle checked at your dealer.
Extreme high or low temperatures or extreme
temperature changes can affect the image
displayed.
Accessory Power Outlet(s)
Your vehicle may be equipped with up to ve accessory
power outlets. The two front outlets, if equipped, are
located under the OnStar
®buttons on the instrument
panel behind hinged doors.
The two middle outlets, if equipped, are located on the
back of the center console.
There may also be an outlet located in the rear of the
vehicle near the liftgate. Remove the cap to use the
outlet. Replace the cap when the outlet is not in use.
If your vehicle is the SUT model, there is an outlet in the
rear cargo area on the passenger’s side of the vehicle.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
Certain power accessory plugs may not be compatible
to the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the
accessory power plugs.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.

Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it xed.
Power Windows and Other
Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is xed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.

nger and pull straight out.

block access door. These can be used to replace a bad
