Although your vehicle may be equipped with a soft top or optional hard top to give the occupants protection from the weather, these tops do not offer structural protection in the event of an accident and do not change the open-body characteristic of the vehicle. Even though your vehicle has a sport bar and side bars for some extra protection, it is a truly open vehicle-there is no structural integrated top and it has low sides and a folding windshield. Many of these vehicles do not have fully enclosed hard doors.

During normal operation, after turning on the ignition switch, the Vehicle Security Alarm Indicator Light will turn on for three seconds for a bulb check. If the light remains on after the bulb check, it indicates that there is a problem with the electronics. In addition, if the light begins to flash after the bulb check, it indicates that someone used an invalid key to try to start the engine. Either of these conditions will result in the engine being shut off after two seconds.
SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors, swing gate, and ignition for unauthorized operation. When the alarm is activated, the system provides both audible and visible signals. The horn, headlights, and tail lights will sound/flash repeatedly for three minutes. If disturbance is still present (driver’s door, passenger door, other doors, ignition) after three minutes, the headlights and tail lights will flash for an additional 15 minutes.
To Set the Alarm
The alarm will set when you use the remote keyless entry (RKE) transmitter to lock the doors and swing gate, or when you use the power door lock switch while the door is open. After all the doors are locked and closed, the Sentry Key/Security Alarm Indicator Light (located on the instrument cluster) will flash rapidly for about 16 seconds to signal that the system is arming. During this 16–second arming period, opening any door or the swing gate will cancel the arming. If the system successfully arms, the Sentry Key/Security Alarm Indicator Light will flash at a slower rate to indicate the alarm is set.
To Disarm the System
To disarm the system, you will need to press the UNLOCK button on the RKE transmitter, or turn the ignition key to the ON position. If something has triggered the system in your absence, the horn will sound three times when you unlock the doors. Check the vehicle for tampering.
The Security Alarm System is designed to protect your vehicle; however, you can create conditions where the system will arm unexpectedly. If you remain in the vehicle and lock the doors with the RKE transmitter, once the system is armed (after 16 seconds), when you pull the door handle to exit, the alarm will sound. If this occurs, press the UNLOCK button on the RKE transmitter to disarm the system. You may also accidentally disarm the system by unlocking the driver’s door with the key and then locking it. The door will be locked but the Security Alarm will not arm.
