Vehicle Security
This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm system.
The indicator light, on the instrument panel near the windshield, indicates the status of the system:
Off: The alarm system is disarmed.
On Solid: The vehicle is secured during the delay to arm the system.
Fast Flash: The vehicle is unsecured. A door, the hood, or the liftgate is open.
Slow Flash: The alarm system is armed.
Arming the Alarm System
- Turn off the vehicle.
- Lock the vehicle in one of two ways:
- Use the RKE transmitter.
- With a door open, press the interior lock.
- After 30 seconds the alarm system will arm, and the indicator light will begin to slowly flash indicating the alarm system is operating.
Pressing the lock button on the RKE transmitter a second time will bypass the 30-second delay and immediately arm the alarm system.
The vehicle alarm system will not arm if the doors are locked with the key. If the driver’s door is opened without first unlocking with the RKE transmitter, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing the lock button on the RKE transmitter during the 10-second pre-alarm, the alarm will be activated. If a door, the hood, or the liftgate is opened without first disarming the system, the turn signals will flash and the horn will sound for about 30 seconds. The alarm system will then re-arm to monitor for the next unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn off the alarm if it has been activated:
Press on the RKE transmitter.- Start the vehicle. To avoid setting off the alarm by accident:
- Lock the vehicle after all occupants have left the vehicle and all doors are closed.
- Always unlock a door with the RKE transmitter. Unlocking the driver door with the key will not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
If the lock is pressed on the RKE transmitter the horn chirps and the lights flash three times, an alarm occurred previously while the alarm system was armed. If the alarm has been activated, a message will appear on the Driver Information Center (DIC).
Immobilizer
This vehicle uses license-exempt transmitters/receivers/systems that operate on a radio frequency that complies with Part 15/ Part 18 of the Federal Communications Commission (FCC) rules and with Innovation, Science and Economic Development (ISED) Canada’s license-exempt RSS(s) / RSP-100 / ICES-GEN.
Operation is subject to the following two conditions:
- The device may not cause harmful interference.
- The device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modifications to any of these systems other than an authorized service facility could void authorization to use this equipment.
Immobilizer Operation
This vehicle has a passive theft-deterrent system. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the vehicle is turned off.
The immobilization system is disarmed when the ignition is on or in accessory mode and a valid remote key is present in the vehicle.
The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system. The system has one or more remote keys matched to an immobilizer control unit in your vehicle. Only a correctly matched remote key will start the vehicle. If the remote key is ever damaged, you may not be able to start your vehicle.
When trying to start the vehicle, the security light may come on briefly when the ignition is turned on. If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again. If the vehicle will not change ignition modes, and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the cupholder. See “Starting the Vehicle with a Low Remote Key Battery” in the Remote Key
Operation.
If the ignition mode will not change with the other remote key or in the cupholder, your vehicle needs service. If the ignition does change modes, the first remote key may be faulty. See your dealer who can service the theft-deterrent system and have a new remote key programmed to the vehicle.
It is possible for the immobilizer system to learn new or replacement remote keys. Up to eight remote keys can be programmed for the vehicle. To program additional remote keys, see “Programming Remote Keys to the Vehicle” under Remote Key Operation.
Do not leave the remote key or device that disarms or deactivates the theft-deterrent system in the vehicle.
