DOOR REQUEST SWITCH OPERATION
When pressing the request switch, it is possible to lock and unlock the door by carrying the Intelligent Key.
OPERATION DESCRIPTION
• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside
key antenna corresponding to the pressed door request swit ch and transmits the request signal to the Intelli-
gent Key. And then, check that the Intelligent Key is near the door.
• If the Intelligent Key is within the outside key antenna 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 door lock/unlock signal and operates each door lock actuator. At the same time, BCM blinks
hazard warning lamp (lock: 2 times, unlock: 1 time) and sounds Intelligent Key buzzer (lock: 1 time, unlock:
1 time) as a reminder.
OPERATION CONDITION
If the following conditions are satisfied, door lock/unl ock operation is performed if the door request switch is
operated:
Key reminder The key reminder buzzer sounds a warning if the door is locked with the key left
inside the vehicle. DLK-27
WarningIf an action that does not meet the operating condition of the Intelligent Key sys-
tem is taken, the buzzer sounds to inform the driver.
DLK-27
Engine start
The engine can be turned on while carrying the Intelligent Key. DLK-22
Interior room lamp control Interior room lamp is controlled according to door lock/unlock state. DLK-20

REMOTE KEYLESS ENTRY FUNCTION
REMOTE KEYLESS ENTRY FUNCT ION : System DescriptionINFOID:0000000012429985
SYSTEM DIAGRAM
REMOTE KEYLESS ENTRY OPERATION
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.
Remote keyless entry system contro ls operation of the following items:
• Auto door lock
• Door lock/unlock
• Hazard and buzzer reminder
OPERATION AREA
To check that the Intelligent Key works normally, us e within 1 m (3 ft) range of each door, however the opera-
ble range may differ according to surroundings.
DOOR LOCK/UNLOCK FUNCTION
• When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is transmitted from Intelligent Key to BCM via remote keyless entry receiver.
• BCM receives the signal and compares it with the registered key ID to the vehicle.
• BCM transmits door lock/unlock signal to each door lock actuator and operates each door lock actuator,
when key ID matches. At the same time, BCM blinks hazard warning lamps (lock: 2 times, unlock: 1 time)
and sounds Intelligent Key buzzer (lock: 1 time) as a reminder.

3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine rpm or
load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
