INFOID:0000000005396599
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start func tion) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).
• Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col- umn to prevent accidental shut-off of the ignition sw itch and locking of the steering wheel during driving con-
dition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key
• Operation of the remote controller buttons on the Inte lligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).
• Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked and the engine started with the mechanical key built into the Intelligent Key.
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It has been made possible to diagnose the system and r egister an Intelligent Key with the CONSULT-III.
DOOR LOCK/UNLOCK FUNCTION

gent Key (without some key operation).
