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 all the 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 in OFF.
The theft deterrent system includes the following features to help protect your vehicle from
theft.

■Setting memory positions
While holding down the SET button, press and
hold one of the memory buttons (1, 2, or 3) until
you hear a beep.
The current position of the seat, as well as the
position of the steering wheel and the outside
rear view mirrors (for the driver's seat only) is
recorded.
■Recalling memory positions
Press one of the memory buttons (1, 2, or 3).
■Linking driving position memory with door unlock operation (driver's seat only)
While holding down the desired memory button,
press and hold the button on the wireless
remote control until you hear a beep.
To prevent triggering of the alarm, open one of
the doors within 30 seconds after the beep is
heard.
The seats can be returned to a previously set position by simply pressing a button.
The position of the steering wheel and the outside rear view mirrors is adjusted along with the
driver's seat.
Positions can be conveniently recorded for the vehicle's primary drivers and passengers.
Linking driving position memory to the door unlock operation allows the memory position
to be recalled automatically when the driver's door is opened. (The linked function does not
operate if the driver's door is unlocked using the mechanical key or manually from inside
the vehicle.)
