INTELLIGENT KEY SYSTEM

System DescriptionBIS000WZ

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock
function) and start the engine (engine start function) by carrying around the Intelligent Key, which operates
based on the results of electrical key-ID verification using two-way communications between the Intelli-
gent Key and the vehicle

Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote keyless entry system. (Remote keyless entry functions)

As an ignition key warning function, when a door lock is locked or unlocked with request switch or remote
controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

Even if the Intelligent Key battery runs down, the door locks can be locked and unlocked and the engine
started with the mechanical key built into the Intelligent Key.

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, change the function setting and register an Intelligent
Key with the CONSULT-II.

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.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.
