on the windshield, blocking your vision.
{Warning
Before driving the vehicle, always clear
snow and ice from the hood, windshield,
washer nozzles, roof, and rear of the
vehicle, including all lamps and windows.
Reduced visibility from snow and ice
buildup could lead to a crash. Clear ice and snow from the wiper blades

Compass Zone
Your dealer will set the correct zone for
your location.
Under certain circumstances, such as during
a long distance cross-country trip or moving
to a new state or province, it will be
necessary to compensate for compass
variance by resetting the zone through the
DIC if the zone is not set correctly.
Compass variance is the difference between
the earth's magnetic north and true
geographic north. If the compass is not set

104 Infotainment System
Occasionally check that the antenna is tight
at the base. If tightening is required, protect
the paint from damage.
Multi-Band Antenna
The multi-band antenna is on the roof of
the vehicle. The antenna is used for OnStar
and the SiriusXM Satellite Radio Service
System if the vehicle has these features. Tall
buildings, hills, trees, heavy foliage, tunnels,
bridges, and garages will affect reception.
Keep the antenna clear of obstructions for
clear reception. Make sure there is sufficient
clearance when entering garages or parking
structures.
Audio Players
Avoiding Untrusted Media Devices
When using media devices such as CDs,
DVDs, Blu-ray Discs, SD cards, USB devices,
and mobile devices, consider the source.
Untrusted media devices could contain files
that affect system operation or performance.
Avoid use if the content or origin cannot be
trusted.
CD Player
Care of the CD Player
Do not add any label to a CD. It could get
caught in the CD player. If a CD is recorded
on a personal computer and a description
label is needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners is not advised,
due to the risk of contaminating the lens of
the CD optics with lubricants internal to the
CD player mechanism.
Caution
If a label is added to a CD, more than
one CD is inserted into the slot at a time,
or an attempt is made to play scratched
or damaged CDs, the CD player could be
damaged. While using the CD player, use
only CDs in good condition without any
label, load one CD at a time, and keep
the CD player and the loading slot free of
foreign materials, liquids, and debris.
If an error displays, see “CD Player
Messages” later in this section.
Care of CDs
If playing a CD-R, the sound quality can be
reduced due to CD-R or CD-RW quality, the
method of recording, the quality of the
music that has been recorded, and the way
the CD-R or CD-RW has been handled.
Handle them carefully. Store CD-Rs or
CD-RWs in their original cases or other
protective cases and away from direct
sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of
a CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly
or not at all. Do not touch the bottom side
of a CD while handling it; this could damage
the surface. Pick up CDs by the outer edges
or the edge of the hole and the outer edge.
If the surface of a CD is soiled, clean it with
a soft, lint-free cloth or dampen a clean, soft
cloth in a mild, neutral detergent solution
mixed with water. Make sure the wiping
process starts from the center to the edge.
Inserting a CD
Insert a CD partway into the slot, label side
up. The player pulls it in and the CD should
begin playing.

138 Driving and Operating
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there as you
hold the key in START for up to
15 seconds. Wait at least 15 seconds
between each try, to allow the cranking
motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briefly but then
stops again, do the same thing. This
clears the extra gasoline from the
engine. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently until
the oil warms up and lubricates all
moving parts.
Fast Idle System
If equipped, this feature is available only
with cruise control. The manual fast idle
switch is operated using the cruise control
buttons on the left side of the steering
wheel.
This system can be used to increase engine
idle speed whenever the following
conditions are met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be moving and the
accelerator must not be pressed.
To control the fast idle:
.To enable the Fast Idle System, press and
release the cruise control on/off button
and ensure that the switch indicator light
is lit.
.Press and release the cruise control SET-
button. Engine speed will be held at
approximately 1200 rpm.
When the fast idle is active, the Driver
Information Center (DIC) will display FAST
IDLE ON.
One of the following actions will turn off
the fast idle:
.Pressing the brake.
.Selecting the cruise control cancel button.
.Releasing the parking brake.
.Moving the transmission shift lever out of
P (Park) or N (Neutral).
.Selecting the cruise control on/off button
when it was previously on.
.Pressing the cruise control SET- button a
second time.
.Pressing the accelerator more than
one-quarter of the way down.
.Turning the ignition off.
Retained Accessory Power (RAP)
When the ignition is turned from on to off,
the following features (if equipped) will
continue to function for up to 10 minutes,
or until the driver door is opened. These
features will also work when the ignition is
in RUN or ACC/ACCESSORY:
.Infotainment System
.Power Windows (during RAP this
functionality will be lost when any door
is opened)
.Sunroof (during RAP this functionality will
be lost when any door is opened)

Engine Coolant Heater
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
The engine coolant heater can provide easier
starting and better fuel economy during
engine warm-up in cold weather conditions
at or below −18 °C (0 °F). Vehicles with an
engine coolant heater should be plugged in
at least four hours before starting.
An internal thermostat in the plug end of
the cord may exist which will prevent
engine coolant heater operation at
temperatures above −18 °C (0 °F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The cord for the engine coolant heater is
on the driver side of the engine
compartment.
Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
.While in use, do not let the heater
cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
