IMMOBILIZER SYSTEM
8-63
EAS27670
GENERAL INFORMATION
This vehicle is equipped with an immobilizer system to help prevent theft by re-registering codes in the
standard keys. This system consists of the following:
• a code re-registering key (with a red bow)
• two standard keys (with a black bow) that can be re-registered with new codes
• a transponder (installed in the red key bow)
• an immobilizer unit
• the ECU
• an immobilizer system indicator light
The key with the red bow is used to register codes in each standard key. Do not use the key with the
red bow for driving. It should only be used for re-registering new codes in the standard keys. The im-
mobilizer system cannot be operated with a new key until the key is registered with a code. If you lose
the code re-registering key, the ECU and main switch (equipped with the immobilizer unit) need to be
replaced.
Therefore, always use a standard key for driving. (See NOTICE.)
TIP
Each standard key is registered during production, therefore re-registering at purchase is not neces-
sary.

• DO NOT LOSE THE CODE RE-REGISTERING KEY! If the code re-registering key is lost, regis-
tering new codes in the standard keys is impossible. The standard keys can still be used to
start the vehicle. However, if code re-registering is required (e.g., if a new standard key is made
or all keys are lost) the entire immobilizer system must be replaced. Therefore, it is highly rec-
ommended to use either standard key for driving, and to keep the code re-registering key in a
safe place.
• Do not submerse the keys in water.
• Do not expose the keys to excessively high temperatures.
• Do not place the keys close to magnets (this includes, but is not limited to, products such as
speakers, etc.).
• Do not place heavy items on the keys.
• Do not grind the keys or alter their shape.
• Do not disassemble the key bows.
• Do not put two keys of any immobilizer system on the same key ring.
• Keep the standard keys as well as other immobilizer system keys away from the code re-reg-
istering key.
• Keep other immobilizer system keys away from the main switch as they may cause signal in-
terference.
