roll, even if the shift lever is in PARK (P).
So, be sure the transfer case is in a drive
gear — not in NEUTRAL. Always set the
parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 157.

®, Compass and
Temperature Display
Your vehicle may have this feature. When on, the
automatic dimming mirror dims to the proper level
to minimize glare from lights behind you after dark.
The mirror has a dual display in the upper right
corner of the mirror face that shows the compass
reading and the outside temperature.
Control buttons for the OnStar
®system are at the
bottom of the mirror. SeeOnStar®System on
page 173for more information about the services
OnStar

Outside Convex Mirror
Your passenger’s side mirror may have convex
glass. A convex mirror’s surface is curved so you
can see more from the driver’s seat.
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than they
really are. If you cut too sharply into the
right lane, you could hit a vehicle on your
right. Check your inside mirror or glance
over your shoulder before changing lanes.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed,
the heated mirrors are also turned on. See “Rear
Window Defogger” underDual Automatic Climate
Control System on page 231orClimate Control
System on page 227for more information.

How OnStar®Service Works
In order to provide you with OnStar®services, your
vehicle’s OnStar®system has the capability of
recording and transmitting vehicle information. This
information is automatically sent to an OnStar
®Call
Center at the time of an OnStar®button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually
includes your GPS location and, in the event of a
crash, additional information regarding the accident
that your vehicle has been involved in (e.g. the
direction from which your vehicle was hit). When
you use the Virtual Advisor feature of OnStar
®
Hands-Free Calling, your vehicle also sends
OnStar®your GPS location so that we can provide
you with location-based services.
OnStar
®service cannot work unless your vehicle is
in a place where OnStar®has an agreement with a
wireless service provider for service in that area.
OnStar
®service also cannot work unless you are in
a place where the wireless service provider
OnStar
®has hired for that area has coverage,
network capacity and reception when the service is
needed, and technology that is compatible with the
OnStar
®service.Not all services are available everywhere,
particularly in remote or enclosed areas, or at
all times.
OnStar
®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available in
that place as well.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
®
equipment to operate. There are other problems
OnStar®cannot control that may prevent OnStar®
from providing OnStar®service to you at any
particular time or place. Some examples are
damage to important parts of your vehicle in an
accident, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar®advisor. If the light next to the
OnStar®buttons is red, this means that your system
is not functioning properly and should be checked
by your dealer/retailer. If the light appears clear (no
light is appearing), your OnStar
®subscription has
expired. You can always press the OnStar®button
to conrm that your OnStar®equipment is active.

Universal Home Remote System
The Universal Home Remote System provides a
way to replace up to three hand-held
Radio-Frequency (RF) transmitters used to
activate devices such as garage door openers,
security systems, and home lighting.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode
(LED) indicator light above the Universal Home
Remote buttons, follow the instructions below.
Do not use the Universal Home Remote with any
garage door opener that does not have the
stop and reverse feature. This includes any garage
door opener model manufactured before April 1,
1982. If you have a newer garage door opener
with rolling codes, please be sure to follow Steps
6 through 8 to complete the programming of
your Universal Home Remote Transmitter.
Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps

Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the button is located on the instrument panel
to the left of the steering column and below the
dome lamp override button.
The ignition must be in RUN and the parking
lamps must be on for the fog lamps to work.
To turn the fog lamps on, press the fog lamps
button. A light comes on in the instrument
panel cluster to let you know that the fog lamps
are on. Press the button again to turn the fog
lamps off.
When the fog lamps are turned on, the low-beam
headlamps automatically turn on.
The fog lamps turn off while you change to
high-beam headlamps. When the high-beam
headlamps go off, the fog lamps will come
on again.
Fog lamps should only be used in foggy conditions
since they could be distracting to oncoming
drivers in clear weather conditions.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualied
service center to install an auxiliary roof lamp.
This button is located
on the overhead
console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the
button will activate the lamp and illuminate an
indicator light at the bottom of this button. Pressing
the top of the button will turn off the roof mounted
lamp and indicator.
The emergency roof lamp circuit is fused at
30 amps, so the total current draw of the attached
lamps should be less than this value. The
attachment points for the roof lamp circuits are
two blunt cut wires located above the overhead
console, a dark green switched power wire and a
black ground wire.

The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast enough at
idle to produce all the power that is needed for very
high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 270.
Battery Run-Down Protection
This feature shuts off the dome, and reading
lamps if they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from running down.
