Heated Seats
If your vehicle is equipped
with heated front seats, the
buttons are located on
the climate control panel.
There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI and
off. The active setting appears on the climate control
panel display. The LO setting warms the seatback and
cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.To turn on the heated seats, press the button once. The
seat will heat to the HI setting. Press the button again
to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press the
button again.

Programmable Automatic Door
Locks
Your vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved
out of PARK (P), all the doors will lock. The front
door inside handles will remain active. The doors will
unlock every time you stop the vehicle and move
the shift lever back into PARK (P).
If someone needs to exit the vehicle once the doors are
locked, have that person use the manual lever or
power door lock switch for the rear doors. The front
doors will remain unlocked from inside the vehicle.
When the door is closed again, it will not lock
automatically. Use the manual lever or the power door
lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Personalization
on page 3-66.
Rear Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security locks
are located on the inside
edge of each rear door.
You must open the rear
doors to access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®
The vehicle may have an automatic dimming inside
rearview mirror with OnStar®controls. For more
information about OnStar®, seeOnStar®System on
page 2-40.
O(On/Off):The on/off button, located on the lower
left side of the mirror, is used for the automatic dimming
functions of the rearview mirror.
Mirror Operation
The automatic dimming feature comes on each time the
vehicle is started. Automatic dimming reduces the
glare of lights from behind the vehicle.
To turn the automatic dimming feature on or off, press
and release the on/off button. The indicator light will
illuminate when this feature is on.
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.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
The vehicle may have an automatic dimming inside
rearview mirror with a compass and OnStar®controls.
For more information about OnStar®, seeOnStar®
System on page 2-40.
The mirror has an eight-point compass display in the
upper right corner of the mirror. When on, the compass
automatically calibrates, or sets the driving direction,
as the vehicle is driven. If the vehicle has the navigation
option, the direction the vehicle is facing will be
displayed on the navigation screen.
Y(On/Off):The on/off button is located on the lower
left side of the mirror and is used for the automatic
dimming and compass functions of the rearview mirror.

Mirror Operation
The automatic dimming feature comes on each time the
vehicle is started.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will illuminate
when this feature is on.
Compass Operation
Press the on/off button twice to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the current compass direction.
Compass Calibration
If after two 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
letter C appears in the compass window, the compass
may need to be reset or calibrated.The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
The compass can be calibrated by pressing and holding
the on/off button until a C is shown in the compass
display.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the mirror
is not adjusted for compass variance, the compass
could give false readings.
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if the vehicle is
driven outside zone eight. Under certain circumstances,
such as a long distance, cross-country trip, it will be
necessary to adjust the compass variance.
2-36
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the zone map that follows.2. Press and hold the on/off button until a zone
number appears on the display.
3. Once the zone number appears on the display,
press the on/off button quickly until you reach
the correct zone number. If C appears in the
compass window, the compass may need
calibration. See “Compass Calibration” listed
previously.
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.
