Section 2 Features and Controls
2-1

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement is
necessary. See ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock your doors from about 3 feet
(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle.
K(Unlock):Pressing this
button once will unlock the
driver's door. The interior
lamps will come on.
Pressing unlock again
within three seconds will
cause the remaining doors
to unlock.
You can choose different feedback options for each
press of the unlock button, such as having the vehicle's
perimeter lamps come on and/or having the horn
chirp. See
DIC Operation and Displays on page 3-46for
more information.
2-5

Q(Lock):Pressing this button once will lock all of the
doors. Pressing the button again within three seconds
may cause the horn to chirp for lock con®rmation.
You can choose different feedback options for each
press of the lock button, such as having the vehicle's
perimeter lamps ¯ash and/or having the horn chirp. See
DIC Operation and Displays on page 3-46for more
information.
L(Panic):When this button is pressed, the horn will
sound and the headlamps and taillamps will ¯ash for
up to 30 seconds. This can be turned off by pressing the
button again, or by waiting for 30 seconds, or by
starting the vehicle.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
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.
2-6

Power Door Locks
The power door lock
switches are located on
the driver's and front
passenger's armrests.
Q(Lock):Remove the ignition key and press the lock
symbol to lock all of the doors.
If the delayed locking feature is on, the doors will not
lock until ®ve seconds after the last door is closed. Press
the lock symbol twice to override this feature and lock
all of the doors immediately. See
Delayed Locking
on page 2-9for more information.
K(Unlock):To unlock the doors, press the unlock
symbol.
Delayed Locking
When locking the doors with the power lock switch or
the keyless entry transmitter and a door or the liftgate (if
equipped) is open, the delayed locking feature will
delay locking the doors until ®ve seconds after the last
door is closed. You will hear three chimes to signal
that the delayed locking feature is in use.
Pressing the power lock switch or the lock button on the
keyless entry transmitter twice will override the
delayed locking feature and immediately lock all
the doors.
You can turn the delayed locking feature off or back on
again by doing the following:
1. Press and hold the power door lock switch in the
lock position.
2. Press unlock twice on the remote keyless entry
transmitter.
This feature will not operate if the key is in the ignition.
You can also program this feature using the DIC.
See ªDelayed Lockingº under
DIC Operation and
Displays on page 3-46.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž, Compass and
Temperature Display
Your vehicle may have this feature. When on, an
automatic dimming mirror automatically dims to the
proper level to minimize glare from lights behind
you after dark.
The mirror also includes a dual display in the upper
right corner of the mirror face. The compass reading and
the outside temperature will both appear in the display
at the same time.
P(On/Off):This is the on/off button.
Temperature and Compass Display
Press the on/off button, located to the far left, brie¯y to
turn the compass/temperature display on or off.
If the display reads CAL, you will need to calibrate the
compass. For more information on calibration, see
below.
To adjust between Fahrenheit and Celsius do the
following:
1. Press and hold the on/off button for approximately
four seconds until either a ¯ashing ÉF, or ÉC
appears.
2. Press the button again to change the display to the
desired unit of measurement. After approximately
four seconds of inactivity, the new unit will be locked
in and the compass/temperature display will
return.
If an abnormal temperature reading is displayed for an
extended period of time, please consult your dealer.
Under certain circumstances, a delay in updating
the temperature is normal.

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 green indicator light, located to
the left of the on/off button, is lit. If it's not, press
and hold the on/off button for approximately
six seconds until the green 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 for
approximately six seconds, until the green indicator
light turns off.
Compass Variance
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 you live outside of
zone eight. Under certain circumstances, as during a
long distance cross-country trip, it will be necessary to
adjust for compass variance. Compass variance is
the difference between earth's magnetic north and true
geographic north. 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 until a Z and a
zone number appears in the display. The compass
is now in zone mode.
2-33

3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the compass/temperature display will return.
4. Calibrate the compass as described below.
Compass Calibration
The compass may need calibration if one of the
following occurs:
·After approximately ®ve seconds, the display does
not show a compass heading (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, magnetic
note pad holder or a similar magnetic item.
·The compass does not display the correct heading
and the compass zone variance is set correctly.In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
the on/off button for approximately 12 seconds or
until CAL is displayed.
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.
Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
If your vehicle has this feature, the mirror will display the
word ON, or an air bag symbol in Canada, when the
passenger air bag is enabled. For more information, see
Passenger Sensing System on page 1-81.
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.

Outside Automatic Dimming Mirror
with Curb View Assist
Your vehicle may have this feature.
The driver's outside mirror will adjust for the glare of the
headlamps behind you. See
Automatic Dimming
Rearview Mirror with OnStarž, Compass and
Temperature Display on page 2-32.
Your vehicle's mirrors will also be capable of performing
the curb view assist mirror function. This feature will
cause the passenger's and/or driver's mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R). This feature may be useful in allowing
you to view the curb when you are parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger's and/or
driver's mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. See
Driver Information Center
(DIC) on page 3-46for more information.
