• Do not clean with ultrasonic cleaners.
• Do not leave the key where it may be exposed to high temperature or high humidity.
• If you lose your key, to prevent the theft of the vehicle immediately contact an authorized Mitsubishi Motors dealer.
• If you notify an authorized Mitsubishi Motors dealer of the key number, they can make a new key. The key number is stamped on the key number plate. Keep the key number plate in a safe place separate from the key itself.
• No keys other than those registered in advance can be used to start the engine. Refer to “Electronic immobilizer (Anti-theft starting system)”.
• Refer to “Free-hand Advanced Security Transmitter (F.A.S.T.-key): “Electronic immobilizer (Anti-theft starting system)” on.

NOTE When the theft alarm is in the system operational status, the alarm operates if a door is opened after using the key, the door lock knob or the power door lock switch to unlock the vehicle. The system does not enter the preparation status if the keyless entry system or the F.A.S.T. key was not used to lock the vehicle.

Electronic immobilizer (Anti-theft starting system)

CAUTION

• Do not make any alterations or additions to the immobilizer system. Alterations or additions could cause failure of the immobilizer.
• For vehicles equipped with the Free-hand Advanced Security Transmitter (F.A.S.T.-key)]
•  
• For information on operations for vehicles equipped with the Free-hand Advanced Security Transmitter (F.A.S.T.-key), refer to “Free-hand Advanced Security Transmitter (F.A.S.T.-key): Electronic immobilizer (Anti-theft starting system)”

[Except for vehicles equipped with the Free-hand Advanced Security Transmitter (F.A.S.T.-key)] The electronic immobilizer is designed to significantly reduce the possibility of vehicle theft. The purpose of the system is to immobilize the vehicle if an invalid start is attempted. A valid start attempt can only be achieved (subject to certain conditions) using a key “registered” to the immobilizer system. All of the keys provided with your new vehicle have been programmed to the vehicle’s electronics.
NOTE In the following cases, the vehicle may not be able to recognize the registered ID code from the key. This means the engine will not start even when the key is turned to the “START” position. When the key contacts a key ring or other metallic or magnetic object. NOTE

• When the key grip contacts metal of another key
• 
• When the key contacts or is close to other immobilizer keys (including keys of other vehicles)
• 
• In cases like the above, move the offending object(s) away from the key and turn the key back to the “ACC” or “OFF” position. Then try to start the engine again. If the engine does not start, contact an authorized Mitsubishi Motors dealer.
• The key may not operate properly when it is near an object or facility that emits strong electromagnetic waves. NOTE
• The electronic immobilizer is not compatible with commercially available remote starting systems. Use of commercially available remote starting systems may result in vehicle starting problems and a loss of security protection. A system failure is suspected when the ignition switch is turned to the “START” position, and the engine does not start. In such a case, contact an authorized Mitsubishi Motors dealer.

Replacement keys

Only keys that have been programmed to the vehicle’s electronics can be used to start the vehicle. If you lose the key, you can order a key from your authorized Mitsubishi Motors dealer by referring to the key number. To prevent vehicle theft, the ID code for the vehicle keys must be changed. Take your vehicle and all remaining keys to your authorized Mitsubishi Motors dealer to have your ID code changed.

When registration of the ID code is complete, the immobilizer indicator will come on for 3 seconds then go off. If an error occurs, the immobilizer indicator will go off during the procedure.

NOTE

• When the key registration is completed, the immobilizer indicator will come on within 3 seconds of turning the ignition switch to the “ON” position with the blank immobilizer key (specially cut for your vehicle at your Mitsubishi Motors dealer).

If you wish to register another key, perform the process again from step 1. NOTE It is not possible to register a key if:

• the immobilizer indicator goes off during the procedure
• the immobilizer indicator does not come on within 30 seconds after step 4.
• The procedure will be terminated automatically if: a period of 30 seconds or longer elapses from the moment when the first key is turned to the “OFF” position to the moment when the second key is turned to the “ON” position a period of 30 seconds or longer elapses from the moment when the second key is turned to the “OFF” position to the moment when the blank immobilizer key is turned to the “ON” position more than 20 seconds elapses after the immobilizer indicator starts blinking

WARNING Individuals using other electro-medical apparatus besides implantable pacemakers and implantable cardiovascular defibrillators should check with the manufacturer of the apparatus to confirm the effect of the electromagnetic waves used by the F.A.S.T.-key. The waves may affect the operations of the electro-medical apparatus. The operations possible with the F.A.S.T.-key can be modified as stated below.(Keyless entry operations are possible.) For details, contact an authorized Mitsubishi Motors dealer.

• Enabling only the locking and unlocking of the doors and the opening of the trunk lid
• Enabling only the starting of the engine
• Deactivating the F.A.S.T.-key
• The F.A.S.T. key uses weak electromagnetic waves.
• In cases such as the following, the operation may be improper or unstable.
• The vehicle is near a facility that emits strong electromagnetic waves, such as a TV transmitting tower, a power station, a radio station or an airport
• The key is carried together with other communication devices such as cellular phones or radios, or electrical appliances such as computers
• The F.A.S.T.-key touches or is covered by a metal object
