Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
two years.
The battery is weak if the transmitter will not work
at the normal range in any location. If you have
to get close to your vehicle before the transmitter
works, it is probably time to change the battery.
The Driver Information Center (DIC) will display a
KEY FOB # BATTERY LOW message when
the transmitter battery is low. See “KEY FOB #
BATTERY LOW” underDIC Warnings and
Messages on page 199
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery in the remote keyless entry
transmitter do the following:
1. Remove the screw from the back of the
remote keyless entry cover and gently pry the
transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Assemble the transmitter and replace the
screw.
4. Check the operation of the transmitter.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic-dimming
rearview mirror with a compass and the OnStar®
system.
There are three additional buttons for the OnStar
®
system. See your dealer for more information
on the system and how to subscribe to OnStar®.
SeeOnStar®System on page 125for more
information about the services OnStar®provides.
O(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on
automatically each time the ignition is started.
To operate the automatic dimming mirror, do the
following:
1. Make sure the indicator light, located to the
left of the on/off button, is lit. If it’s not, press
and hold the on/off button until the light
comes on, indicating that the mirror is in
automatic dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button until
the indicator light turns off.
Compass Operation
Press the on/off button once to turn the compass
on or off.
There is a compass display in the window in the
upper right corner of the mirror face. The compass
displays a maximum of two characters. For
example, “NE” is displayed for north-east.

Compass Calibration
Press and hold the on/off button to activate the
compass calibration mode. CAL will be displayed
in the compass window on the mirror.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
The mirror is set to zone eight upon leaving
the factory. It will be necessary to adjust the
compass to compensate for compass variance if
you live outside zone eight. Under certain
circumstances, such as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account
for compass variance, your compass could give
false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the following zone map.2. Press and hold the on/off button for
six seconds. Release the button when
(FOR ZONE) is displayed. The number shown
is the current zone number.
3. Scroll through the zone numbers that appear in
the window on the mirror by pressing the on/off
button. Once you nd your zone number,
release the button. After about four seconds,
the mirror will return to the compass display,
and the new zone number will be set.

Section 3 Instrument Panel

ProCarManuals.com
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems, so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system are only
affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system comes on after the
transmission is shifted out of PARK (P). Once you
leave the garage, it will take about one minute
for the automatic headlamp system to change to
DRL if it is light outside. During that delay, the
instrument panel cluster might not be as bright as
usual. Make sure the instrument panel brightness
control is in the full bright position.
If the vehicle is running and the automatic
headlamp system is already on, it can be turned
off by turning and releasing the headlamp
control at the off position. The automatic headlamp
system stays off until you turn and release the
headlamp control at the off position again.
SeeHeadlamps on page 160.Fog Lamps
The fog lamp control is located on the turn
signal/multifunction lever.
Use the fog lamps for better vision in foggy or
misty conditions.
-:The band with this symbol is used to turn the
fog lamps on and off.
When the fog lamps are turned on, the parking
lamps also turn on. A message will also display on
the DIC when the fog lamps are turned on or off.
SeeDriver Information Center (DIC) on page 194.
To turn the fog lamps on or off, turn the fog
lamp band on the lever up to the dot and
release it. The band will return to its original
position.
If you turn on the high-beam headlamps, the
fog lamps will turn off. They will turn back on
again when you switch back to low-beam
headlamps.
When the Fog Lamps are turned on or off, a
message will appear on the Driver Information
Center. SeeDIC Warnings and Messages
on page 199.
Some localities have laws that require the
headlamps to be on along with the fog lamps.

Entry Lighting
The vehicle has entry lighting.
When any door is opened, the dome lamps come
on as long as the dome override lamp override
button is not pressed in. When all the doors
are closed, the lamps stay on for a short period of
time and then turn off automatically. If you use
the Remote Keyless Entry (RKE) transmitter
to unlock the vehicle, the interior lamps come on
for a short time whether or not the dome lamp
override is on.
Exit Lighting
With exit lighting, the interior lamps will come on
when you remove the key from the ignition. If
the dome override is off, these lights will stay on
for a short period of time and then will go out.
Reading Lamps
Press the indented part of the lenses on the
reading lamps located in the overhead console to
turn them on or off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
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.
164
ProCarManuals.com
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 199.Battery Run-Down Protection
This feature shuts off the dome, courtesy, and
vanity lamps if they are left on for more than
20 minutes when the ignition is off. This will keep
the battery from running down.
If the battery run-down protection shuts off the
interior lamps, it may be necessary to do one of
the following to return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to RUN.
This feature will also turn off the parking lamps
and headlamps under most circumstances, if they
are left on. If you would like to turn them back
on, turn the exterior lamps knob.
