tion using two-way communication between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key.
• The settings for each function can be changed with CONSULT.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It is possible to perform a diagnosis on the syst em and register an Intelligent Key with CONSULT.

REMOTE KEYLESS ENTRY F UNCTION : System DiagramINFOID:0000000009461780
REMOTE KEYLESS ENTRY FUNCT ION : System DescriptionINFOID:0000000009461781
The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button.
OPERATION
Remote keyless entry system controls operation of the following items.
• Door lock/unlock function
• Selective unlock function
• Auto door lock function
• Hazard and horn reminder function
• Trunk lid open function
• Remote engine start
OPERATION AREA
The remote engine start operating range is appr oximately 60 m (197 ft) from the vehicle.
REMOTE ENGINE START FUNCTION
• When the lock button and then the remote engine start butt on of the Intelligent Key are pressed within 5 sec-
onds of each other, a start signal is transmitted from Intelligent Key to BCM via remote keyless entry
receiver.
• When the BCM receives the remote engine start signal , it locks all doors, flashes the hazard lamps and
chirps the horn and the engine will then start.
• To exit the remote engine start mode from inside t he vehicle, depress the brake pedal and press the push-
button ignition switch at the same time.
• To cancel the remote engine start mode away from t he vehicle, press the remote engine start button on the
Intelligent Key.
• Once the vehicle has been started using the remote engi ne start feature it will remain running for 10 minutes.
Extended run time can be added to the initial 10 minute running time by pressing the lock button and remote
engine start button within 5 seconds of each other. Th is will add an additional 10 minutes of running time.
Extended time can only be added once, for a total run time of up to 20 minutes.
DOOR LOCK/UNLOCK FUNCTION
• When door lock/unlock button of the Intelligent Key is pr essed, lock signal or unlock signal transmitted from
Intelligent Key to BCM via remote keyless entry receiver.

TRUNK LID OPENER SYSTEM : System DescriptionINFOID:0000000009461790
Only when pressing the request switch, it is possibl e to open the trunk by carrying the Intelligent Key.
• The Intelligent Key system is a system that makes it possible to open the trunk (trunk open function) by car-
rying the Intelligent Key which operates based on the resu lts of electronic ID verification using two-way com-
munications between the Intelli gent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
• 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 trunk is opened with request switch or remote controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer or horns sound (hazard and buzzer/horn reminder function).
• The settings for each functi on can be changed with the CONSULT.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT.
OPERATION DESCRIPTION/TRUNK OPEN
• When the BCM detects that trunk open request switch is pressed, it starts the outside key antenna (trunk
room) and inside key antenna corresponding to the pressed trunk open request switch and transmits the
request signal to the Intelligent Key. And then, c heck that the Intelligent Key is near the trunk.
• If the Intelligent Key is within the outside key ant enna (rear bumper) detection area, it receives the request
signal and transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM transmits the trunk open request signal and sounds Intelligent Key warning buzzer 4 consecutive
times.
• When BCM receives the trunk open request signal, it operates the trunk release solenoid and opens the trunk.
OPERATION CONDITION
If the following conditions are not satisfied, trunk open operation is not performed even if the request switch is
operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.

The outside key antenna detection area of trunk open function is in
the range of approximately 80 cm (31.50 in) surrounding trunk
opener request switch (1). However, this operating range depends
on the ambient conditions.
KEY REMINDER FUNCTION
*:If the door closing impact shocks the door lock knob, or contacts against baggage with the door lock knob, it might activate the door
locks accidentally but unlock operation will be perform at these cases.

times when the Intelligent Key cannot be detected, an d this function will not operate when the Intelli-
gent Key is on the instrument panel, rear parcel shelf, or in the glove box. Also, this system some-
times does not operate if the Intelligent Key is in the door pocket for the open door.
• The key reminder function is operated when the tr unk is opened/closed and the buzzers sound. If the
following operations are performed, the key remind er function is cleared and buzzer sounds are
stopped.
- Remote controller door lock butt on operation of Intelligent Key
- Remote controller door unlock butt on operation of Intelligent Key
- When the trunk is closed, the Intell igent Key is not inside the vehicle
- When any door is open
HAZARD AND BUZZER REMINDER FUNCTION
During trunk opening operation by request switch, the hazard warning lamps and Intelligent Key warning
buzzer will flash or sound as a reminder.
