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:
D
Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
D
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.
D
Check to determine if battery replacement or
synchronization is necessary. See the instructions
that follow.
D
If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
The numbers on the back of the transmitters correspond to
DRIVER #1 and DRIVER #2 on the DIC (if equipped).
See "DIC" in the Index for more information.
Pressing any button will also illuminate the interior lamps
(see "Illuminated Entry" in the Index). All doors will lock
when the button with the lock symbol is pressed.
The trunk will unlock when the trunk button is pressed,
and the ignition is in LOCK or OFF. The trunk button
will also work when the ignition is on, but only while
the transaxle is in PARK (P).
The driver's door will
unlock when the button
with the unlock symbol is
pressed. If pressed again
within five seconds, all the
doors will unlock.
