Theft Deterrent System
■ Engine immobilizer
This system only allows the engine to start if a reg-
istered key is used.
This deters theft caused by the use of unautho-
rized keys.
■ Alarm
Forcibly unlocking the doors, trunk, or hood without the key or wireless remote control
causes the horn to blow and the exterior lights to flash, alerting those in the surrounding
area.
■ Steering lock
The steering wheel is locked when the engine
switch is turned off.
This system is designed to help protect your vehicle from theft.
If the security indicator light is flashing when you leave the vehicle, the engine immobilizer
and alarm are set.
To stop the alarm, unlock the doors or trunk with the key or wireless remote control, or turn
the engine switch to the ON position.
