If you ever notice a decrease in the keyless
access transmitter range, try doing one of the
following:
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 “Battery Replacement”
underKeyless Access System Operation on
page 68.
Check to make sure that an electronic device
such as a cellular phone or lap top computer
is not causing interference.
If you are still having trouble, see your dealer
or a quali ed technician for service.
Keyless Access System Operation
Your vehicle has a Keyless Access System
that allows you to lock and unlock your doors,
unlock your trunk lid and disarm or arm your
theft-deterrent system. The range distance is as
much as 100 feet (30 m) away.
Your vehicle comes with
two transmitters, and up
to four can be matched
to your vehicle. See
“Matching Transmitter(s)
to Your Vehicle” later
in this section.
Q(Lock):Press this button to lock the doors.
The indicator light on the door will ash once.
If this button is pressed twice, the doors will
lock, the light will ash once and the horn will
sound once.

Battery Replacement
Under normal use, the battery in your keyless
access transmitter should last about three years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location. If
you have to get close to your vehicle before the
transmitter works, it is probably time to change the
battery.
A weak battery may also cause the DIC to display
NO FOB DETECTED when you try to start the
vehicle. If this happens, place the transmitter in the
glove box transmitter pocket with the buttons facing
to the right. Then, with the vehicle in PARK (P) or
NEUTRAL (N), press the brake pedal and the
START button. Although this will start the vehicle, it
is recommended that you replace the transmitter
battery as soon as possible. The DIC may display
FOB BATTERY 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.1. Insert a at object with a thin edge into the
slot on the side of the transmitter and
separate the bottom half from the top half.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter,
positive (+) side up. Use a battery, type
CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

OnStar®service cannot work unless your vehicle
is in a place where OnStar®has an agreement
with a wireless service provider for service in that
area. OnStar
®service also cannot work unless
you are in a place where the wireless service
provider OnStar
®has hired for that area
has coverage, network capacity and reception
when the service is needed, and technology that
is compatible with the OnStar
®service. Not all
services are available everywhere, particularly in
remote or enclosed areas, or at all times.
OnStar
®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available in
that place as well.
Your vehicle must have a working electrical
system (including adequate battery power) for the
OnStar
®equipment to operate. There are other
problems OnStar®cannot control that may prevent
OnStar®from providing OnStar®service to you
at any particular time or place. Some examples are
damage to important parts of your vehicle in an
accident, hills, tall buildings, tunnels, weather
or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your
radio to hear the OnStar®advisor. If the light next
to the OnStar®buttons is red, this means that
your system is not functioning properly and should
be checked by a dealer. If the light appears
clear (no light is appearing), your OnStar
®
subscription has expired. You can always press
the OnStar®button to con rm that your OnStar®
equipment is active.
