To Set the Alarm
1. Remove the key from the ignition switch and get out
of the vehicle.
2. Lock the door using either the power door lock switch,
or the Remote Keyless Entry (RKE) transmitter, and close
all doors.
3. The Vehicle Security Light in the instrument cluster
will flash rapidly for 16 seconds. This shows that the
Vehicle Security Alarm is arming. During this period, if a
door is opened, the ignition switch is turned ON, or the
power door locks are unlocked by either the power door
lock switch or the RKE transmitter, the Vehicle Security
Alarm will automatically disarm. After 16 seconds, the
Vehicle Security Light will flash slowly. This shows that
the Vehicle Security Alarm is fully armed.
To Disarm the Alarm
Unlock a front door using the RKE transmitter.
Starting the vehicle with a valid Sentry Key ௡ will disarm
the Vehicle Security Alarm. A valid key is one that is
programmed to that particular vehicle. A valid key will
disarm the Vehicle Security Alarm. An invalid key will
trigger the alarm.
Tamper Alert
If the horn sounds three times when you unlock a front
door using the RKE transmitter, the alarm has been
activated. Check the vehicle for tampering.
