Transmitter Verification
This feature provides feedback that a command has
been received by the keyless entry receiver. The
headlamps and back-up lamps will flash on every lock
and on the first unlock command. The horn will also
sound once for every lock and twice for the first unlock
command. Silent operation and other options may
be selected for this feature. See Vehicle Personalization
on page 2-43.
If your vehicle has the optional content theft-deterrent
system, the first time the remote unlock is received,
three flashes from the headlamps will be seen and
chirps will be heard to indicate an alarm condition has
occurred since last arming. See Content Theft-Deterrent
on page 2- 15.
Illumination on Remote Activation
The interior lamps will come on when either the
UNLOCK, the trunk release or the panic alarm button is
pressed. The interior lamps will remain on for
40 seconds or until the ignition is turned to ON or LOCK
is pressed. Locking the doors with the power door
locks will also cause the lamps to turn off. If a door is
opened during the 40 second period, the interior
lamps will remain on while the door is open.
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.
If you prefer, you can complete this procedure yourself.
See Vehicle Personalization on page 2-43 for more
information.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three 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.
