Topic 1 Entering and Exiting Theft Deterrent System The theft deterrent system includes the following features to help protect your vehicle from theft. Engine immobilizer system The engine immobilizer system prevents the engine from being started in the event that an attempt is made to start the vehicle using an unregistered key. The security indicator light flashes to indicate that the system is set. Alarm The alarm detects forcible entry and attracts attention to the vehicle by sounding the horn and flashing the exterior lights in the event that an attempt is made to forcibly open the doors, trunk or hood that have been locked. When all the doors are locked, the security indicator light comes on to indicate that the alarm is in its preparation state. The indicator light begins to flash after approximately 30 seconds to indicate that the system is armed. Steering lock The steering wheel locks when the engine switch is in OFF mode. To stop the alarm, start the engine or unlock the doors or trunk using the electronic key or the wireless remote control. (The alarm will stop after several seconds.) 9
