Immobilizer 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 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 lockThe 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.

dealer check the system as soon aspossible. (See page 3-12.)
WARNING
EWA10082
If the ABS warning light comes on or
flashes while riding, the brake sys-
tem reverts to conventional braking.
Therefore, be careful not to cause
the wheels to lock during emergen-
cy braking. If the warning light
comes on or flashes while riding,
have a Yamaha dealer check the
brake system as soon as possible.The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should

Multi-function display
WARNING
EWA12313
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract the
operator and increase the risk of an
accident.
The multi-function display is equipped
with the following:
a speedometer (which shows the
riding speed)
a digital tachometer (which shows
engine r/min)
an odometer (which shows the to-
tal distance traveled)
two tripmeters (which show the
distance traveled since they were
last set to zero)
a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter started flashing)
a clock
a fuel meter
a self-diagnosis deviceTIPBe sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.
For the U.K. only: To switch the
speedometer and odometer/trip-
meter displays between kilome-
ters and miles, push the
“SELECT” and “RESET” buttons
together, then while holding thebuttons, turn the key to “ON”.
When the digits start flashing,
push the “SELECT” button to
change between kilometers and
miles.
Tachometer
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ON”, the ta-
chometer needle sweeps once across
the r/min range and then returns to
zero r/min in order to test the electrical
circuit.

Pushing the “SELECT” button switch-
es the display between the tripmeter
modes “TRIP 1” and “TRIP 2” in the
following order:
TRIP 1 → TRIP 2 → TRIP 1When the fuel amount in the fuel tank
decreases to XT660Z 6.7 L (1.77 US
gal, 1.47 Imp.gal) - XT660ZA 5.8 L
(1.53 US gal, 1.28 Imp.gal), the bottom
segment of the fuel meter starts flash-
ing, and the tripmeter display automat-
ically changes to the fuel reserve
tripmeter mode “F-TRIP” and starts
counting the distance traveled from
that point. In that case, pushing the
“SELECT” button switches the display
between the various tripmeter modes
in the following order:
F-TRIP → TRIP 1 → TRIP 2 → F-TRIP
To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
four seconds. If you do not reset the
fuel reserve tripmeter manually, it re-
sets itself automatically and the display
returns to the prior mode after refueling
and traveling 5 km (3 mi).Clock mode
