Mirrors
Manual Rearview Mirror
To reduce glare from lamps behind you, move the
lever toward you to the night position. Your
vehicle may also have reading lamps. Press the
buttons, located under the mirror, up to turn
the lamps on or off.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming
rearview mirror with OnStar®, compass and
reading lamps. This feature enables the mirror to
sense nighttime glare from vehicle headlamps
from behind and automatically dim to reduce the
glare to a safe level.
O(On/Off):This is the on/off button for the
automatic dimming feature.
The automatic dimming feature turns on each time
the vehicle is started. Press and hold the on/off
button once and the green indicator light located to
the left of the button will go out indicating thefeature is off. To turn the feature back on, press
and hold the on/off button and the green indicator
light will come on.
The reading lamps, located under the mirror, can
be turned on or off by pushing the buttons up.
There are three additional buttons for the OnStar
®
system. See your dealer for more information on
the system and how to subscribe to OnStar®. See
OnStar®in the Index for more information.
Compass Operation
Press the on/off button once to turn the compass
on or off.
When the ignition and the compass feature are on,
the compass will show two character boxes for a
few seconds. After a few seconds, the mirror will
display the current compass direction.
Compass Calibration
If after a few seconds the display does not show a
compass direction, (N for North for example),
there may be a strong magnetic eld interfering
with the compass. Such interference may be
caused by a magnetic antenna mount, note pad
holder, or similar object. If the word CAL appears
in the compass window, the compass may
need to be reset or calibrated.

Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner. Do
not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter the
mirror housing.

Mirror Reading Lamps
Your vehicle may have reading lamps on the
rearview mirror. Push the button to turn the reading
lamps on and off. The reading lamps will
automatically come on when a door is open.
Rear Reading Lamps
Push the lens to turn the reading lamps on
and 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.
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.
Battery Run-Down Protection
Your vehicle has a battery saver feature designed
to protect your vehicle’s battery.
When any interior lamp is left on and the ignition
is turned off, the battery rundown protection
system will automatically turn the lamp off after
20 minutes. This will avoid draining the battery.

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
If you have the Anti-Lock Brake System (ABS),
remember: It helps avoid only the braking skid. If
you do not have ABS, then in a braking skid,
where the wheels are no longer rolling, release
enough pressure on the brakes to get the wheels
rolling again. This restores steering control.
Push the brake pedal down steadily when you
have to stop suddenly. As long as the wheels are
rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.
