dow)When the ignition knob is pressed in so that it can be rotated (or has been rotated), if the
vehicle speed is less than 5 km per hour, the Intelligent Key unit compares the key-ID with
that of the Intelligent Key every 30 seconds using the inside key antenna, if the results of
the comparison are NG (the Intelligent Key is not found)
Note: The factory setting for this function is OFF.
Door lock non-operation warningWhen any of the following conditions are met

When the Intelligent Key is inside the car and the ignition knob is not pressed, when an
attempt is made to lock a door lock with a door request switch
NOTE:
This warning is issued even if the Intelligent Key is not in the out side key antenna detec-
tion area corresponding to the door request switch was operated.

When the ignition knob is pressed, when an attempt is made to lock a door lock with a
door request switch
NOTE:
This warning is only issued if the Intelligent Key is in the out side key antenna detection
area corresponding to the door request switch was operated.

When any of the doors is open, when an attempt is made to lock a door lock with a door
request switch
NOTE:
This warning is only issued if the Intelligent Key is in the out side key antenna detection
area corresponding to the door request switch was operated.
Intelligent Key low battery pre-
warningThis warning is issued when it is detected that the battery in the Intelligent Key has been
used up.

INTELLIGENT KEY SYSTEM

CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II or Intelligent Key operation.
Changing Settings With the Intelligent Key
Intelligent Key remote controller button and door request switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure
1. With the ignition switch is in the LOCK position (ignition knob not pressed), hold down both the LOCK and
UNLOCK remote control buttons on the Intelligent Key at the same time for at least 10 seconds (The yard-
stick is that the Intelligent Key LED flashes 20 times.)
2. Within 5 seconds of releasing the Intelligent Key remote controller buttons, press the driver door request
switch.
3. The KEY warning lamp in combination meter lights up for 3 seconds (engine starting enabled → starting
disabled: lights up red, engine starting disabled → flashes green). This completes the settings change.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-94, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-II. Up to 4 can be registered.
CAUTION:

After a new Intelligent Key-ID is registered, be sure to check the function.

When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see the CONSULT-II Operation Manual NATS.

STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:

The method for registering a steering lock unit ID depends on the status of the steering lock unit
and Intelligent Key unit (new or old unit).

After registration is completed, press ignition knob with a portable unit in the vehicle so that it can
be rotated, and confirm that it cannot be rotated even when ignition switch is pressed without a
portable unit in the vehicle.
For future information, see the CONSULT-II Operation Manual NATS.
CAN Communication System DescriptionBIS000X0
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBIS000X1
Refer to LAN-49, "CAN System Specification Chart" .
