Mirrors
Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming rearview
mirror with OnStar®and/or a compass display.
Vehicles with OnStar have three control buttons located
at the bottom of the mirror. See your dealer/retailer for
more information on the system and how to subscribe to
OnStar. SeeOnStar
®System on page 2-46for more
information about the services OnStar provides.
O(On/Off):Press to turn the dimming feature on or off.
Automatic Dimming Mirror Operation
Automatic dimming reduces the glare of lights from
behind the vehicle. The dimming feature comes on and
the indicator light illuminates each time the vehicle is
started.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror. Use a
soft towel dampened with water.
Compass
Compass Operation
There is a compass display in the upper right corner of
the mirror.
Press
Oto turn the compass display on or off.
Compass Calibration
Press and holdOto activate the compass calibration
mode. CAL displays 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.
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.
Interference can be caused by a magnetic antenna
mount, note pad holder, or similar object. If CAL displays
in the compass window, the compass may need to be
reset or calibrated.

Compass Variance
The compass is set to zone eight. If you do not live
in zone eight or drive out of the area, the compass
variance needs to be changed to the appropriate zone.
To adjust for compass variance:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold
Ountil the zone number displays.
The number shown is the current zone number.
3. Once the zone number displays, press
Orepeatedly
until the correct zone number displays. Stop pressing
the button and the mirror returns to normal operation.
If CAL appears in the compass window, the compass
may need calibration. See “Compass Calibration”
listed previously.

Park Tilt Mirrors
If the vehicle has memory mirrors, the outside mirrors
have park tilt mirrors. This feature tilts the driver’s side
and passenger side mirror to a factory programmed
position when the vehicle is in R (Reverse). This feature
may be useful in allowing you to view the curb when you
are parallel parking.
When the vehicle is shifted out of R (Reverse) and
either a ve second delay has occurred, or the ignition
is turned to LOCK/OFF, the driver’s and passenger
side mirrors return to their original position.
SeeDIC Vehicle Customization on page 3-66for more
information.
Outside Convex Mirror
{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 the right. Check the inside mirror or
glance over your shoulder before changing lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
Outside Heated Mirrors
For vehicles with this feature:
<(Rear Window Defogger):Press to heat the
mirrors. See “Rear Window Defogger” underClimate
Control System on page 3-21orDual Automatic Climate
Control System on page 3-24for more information.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 5mph (8 km/h), and assists the driver
with parking and avoiding objects while in R (Reverse).
The sensors on the rear bumper are used to detect
the distance to an object up to 8 feet (2.5 m) behind
the vehicle, and at least 10 inches (25.4 cm) off
the ground.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
objects that are below the bumper,
underneath the vehicle, or if they are
too close or far from the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle’s mirrors.
The display is located on
the rear shelf, below the
rear window, and can
be seen by looking over
your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.

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 bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a 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 are on, such as: 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,
BATTERY VOLTAGE LOW, or LOW BATTERY. 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 3-56.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage door
opener. When the ignition is turned off, the power to
these features will automatically turn off after 10 minutes.
Power will be restored for an additional 10 minutes if any
door is opened, the trunk is opened or the courtesy lamp
switch is turned on.
