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 only 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.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the transmitter
battery is low.
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.

with a compass and the OnStar system.
This is the on/off button.There are three buttons for the OnStar system. See your
dealer for more information on the system and how to
subscribe to OnStar. See ªOnStar

Systemº in the Index
for more information about the services OnStar provides.

dims to the proper level to minimize glare from any
headlamps behind you after dark.
The automatic dimming feature is turned on and off by
pressing the far left button, located on the lower part of
the mirror face, for up to three seconds. A light on the
mirror will be lit when the feature is turned on. It will go
out when the feature is turned off.

Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. ªCALº will be
displayed in the compass window on the mirror.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display shows ªCAL,º or

drive the vehicle on your everyday routine.
(This method may take longer to calibrate).
Compass Variance
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. 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 map.2. Press and hold the on/off button for six seconds.
Release the button when ªZONEº is displayed.
The number shown is the current zone number.
3. Scroll through the zone numbers that appear in the
compass/temperature window on the mirror by
pressing the on/off button. Once you find your zone
number, release the button. After about four seconds,
the mirror will return to the compass and
temperature display, and the new zone number will
