Immobilizer system 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
light (See page 3-5.)
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
ECA11821
●
DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
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 immobi-
lizer system must be replaced.
Therefore, it is highly recom-mended to use either standard
key and keep the code re-regis-
tering key in a safe place.
●
Do not submerse any key in wa-
ter.
●
Do not expose any key to exces-
sively 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 transmit
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 im-
mobilizer 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.

Main switch/steering lock The main switch/steering lock controls
the ignition and lighting systems, and is
used to lock the steering. The various
positions are described below.TIPBe 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.
