Immobilizer system

1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an immo-
bilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the fol-
lowing:

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 (which is installed in
the code re-registering key)

an immobilizer unit

an ECU

an immobilizer system indicator
EAU10978 light (See page 5-7.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to
a Yamaha dealer to have them re-reg-
istered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
NOTICE

DO NOT LOSE THE CODE
RE-REGISTERING KEY! CON-
TACT YOUR DEALER IMMEDI-
ATELY IF IT IS LOST! If the code
re-registering key is lost, regis-
tering new codes in the stan-
dard 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 en-
tire 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
