Theft Deterrent System
■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 system sounds the alarm and flashes lights when forcible entry is detected.
To set the alarm: lock both side doors from outside the vehicle. The security indicator light
comes on to indicate that the alarm is in its preparation state. When the indicator light
begins to flash, the system is armed.
To deactivate or stop the alarm: turn the “ENGINE START STOP” switch to ACCESSORY
or IGNITION ON mode, or unlock the doors or trunk using the electronic key or the wire-
less remote control.
■Steering lock
The steering wheel locks when the “ENGINE
START STOP” switch is OFF and the driver’s door
is opened.
When the steering lock cannot be released, the
green indicator light on the “ENGINE START
STOP” switch will flash and a message will be
shown on the multi-information display. To release
it, gently turn the wheel left or right while pressing
the “ENGINE START STOP” switch.
