IMMOBILIZER SYSTEM
GENERAL INFORMATION
This vehicle is equipped with an immobilizer system to help prevent theft by registering codes in
standard keys. This system consists of the following:
• a code re-registering key (with a red bow)
• two standard keys (with black bows) that can be re-registered with new codes
• transponders (one installed in each key bow)
• an immobilizer antenna
• a CDI unit
• 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 registering new codes in the standard keys. The
immobilizer system cannot be operated with a new standard key until a code is registered in the
key. If you lose the code re-registering key, the main switch, and CDI unit must be replaced. There-
fore, always use a standard key for driving.
NOTE:
Each standard key is registered during production, therefore, registering the keys at purchase is not
necessary.
1 Code re-registering key (red bow)
2 Standard keys (black bow)
CAUTION:
• DO NOT LOSE THE CODE RE-REGISTERING KEY! If the code re-registering key is lost, reg-
istering 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 (i.e., if a new standard key is
made or all keys are lost) the entire immobilizer system must be replaced. Therefore, it is
highly recommended to use either standard key and 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 not limited to, products such as
speakers, etc.).
• Do not place heavy items on the keys.
• Do not grind the keys items or alter their shape.
• Do not disassemble the keys 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-
registering key.
• Keep other immobilizer system keys away from the main switch as they may cause signal
interference.
