If you set off the alarm by accident,
press unlock on the RKE transmitter
or place the key in the ignition and
turn it to START to turn off the
alarm. The alarm will not stop if you
try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lowerthe driver window and open the
driver door.
2. Activate the system by locking the doors with the power door
lock switch while the door is
open, or with the RKE
transmitter.
3. Get out of the vehicle, close the door and wait for the security
light to go out.
4. Then reach in through the window, unlock the door with the
manual door lock and open the
door. This should set off the
alarm. While the alarm is set, the power
door unlock switch will not work.
If the alarm does not sound when it
should but the headlamps flash,
check to see if the horn works. The
horn fuse may be blown. To replace
the fuse, see
Instrument Panel Fuse
Block on page 10‑46 andEngine
Compartment Fuse Block on
page 10‑41.
If the alarm does not sound or the
headlamps do not flash, the vehicle
should be serviced by your dealer.
