Immo bilizer systemThis 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
light (See page 3-5.)
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 standard
key for driving.
NOTICE
ECA11822
DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the co de re-re g-
isterin g key is lost, reg istering
new co des in the stan dar d keys
is impossib le. The stan dar d
keys can still be used to start
the vehicle, however if cod e re-
re gisterin g is require d (i.e., if a
new stan dar d key is mad e or all
keys are lost) the entire immo bi-
lizer system must b e replaced.
Therefore, it is hi ghly recom- men
ded to use either stan dar d
key an d keep the co de re-reg is-
tering key in a safe place.
Do not su bmerse any key in wa-
ter.
Do not expose any key to exces-
sively hi gh temperatures.
Do not place any key close to
ma gnets (this inclu des, but not
limite d to, pro ducts such as
speakers, etc.).
Do n o
t place items that transmit
electrical si gnals close to any
key.
Do not place heavy items on any
key.
Do not grin d any key or alter its
shape.
Do not d isassemble the plastic
part of any key.
Do not put two keys of any im-
mo bilizer system on the same
key rin g.
Keep the stan dar d keys as well
as keys of other immo bilizer
systems away from this vehi-
cle’s cod e re-registering key.

30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer system is enabled. After 24

hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobilizer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.
TIPIf the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following. 1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting. 2. Use the code re-registering key to
start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.
