Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
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 (which is installed
in the code re-registering key)
an immobilizer unit
an ECU
an immobilizer system indicator
light (See page 3-4).
The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult pro-
cess, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the
key with the red bow for driving. It
should only be used for re-registering
the standard keys. Always use a stan-
dard key for driving.
ECA11821
DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-
registering key is lost, registe-
ring new codes in the standard
keys is impossible. The stan-
dard 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 ishighly recommended to use
either standard key and keep
the code re-registering key in a
safe place.
Do not submerse any key in
water.
Do not expose any key to
excessively high temperatures.
Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
Do not place items that trans-
mit electrical signals close to
any key.
Do not place heavy items on
any key.
Do not grind any key or alter its
shape.
Do not disassemble the plastic
part of any key.
Do not put two keys of any
immobilizer system on the
same key ring.
Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle’s code re-registering key.

various positions are described
below.
TIP
Be sure to use the standard key
(black bow) for regular use of the
vehicle. To minimize the risk of losing
the code re-registering key (red bow),
keep it in a safe place and only use it
for code re-registering.
