Immobilizer system indicator light
“”
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”, or if the indicator light remains
on, have a Yamaha dealer check the
electrical circuit.
When the key is turned to “OFF” and
30 seconds have passed, the indica-
tor light will start flashing indicating
the immobilizer system is enabled.
After 24 hours have passed, the indi-
cator light will stop flashing, however
the immobilizer system is still ena-
bled.
The self-diagnosis device also
detects problems in the immobilizer
system circuits. (See 3-8 for an expla-
nation of the self-diagnosis device.)

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 equip-
ped with the following:
a speedometer (which shows the
riding speed)
a digital tachometer (which
shows engine r/min)
an odometer (which shows the
total 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 sin-
ce the bottom segment of the
fuel meter started flashing)
a clock
a fuel meter
a self-diagnosis device
TIP
Be sure to turn the key to “ON”
before using the “SELECT” and
“RESET” 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 the

buttons, turn the key to “ON”.
When the digits start flashing,
push the “SELECT” button to
change between kilometers and
miles.
Tachometer
1. Tachometer
2. Tachometer red zone
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
tachometer needle sweeps once
across the r/min range and then
returns to zero r/min in order to test
the electrical circuit.

Do not operate the engine in the
tachometer red zone.
Red zone: 7500 r/min and above

Pushing the “SELECT” button swit-
ches the display between the tripme-
ter 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 (1.76 US
gal, 1.46 Imp.gal) - XT660ZA 5.8 L
(1.53 US gal, 1.28 Imp.gal), the bot-
tom segment of the fuel meter starts
flashing, and the tripmeter display
automatically 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 pus-
hing 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
resets itself automatically and the dis-
play returns to the prior mode after
refueling and traveling 5 km (3 mi).

eyes, see your doctor immediately.
If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.

Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been desig-
ned to use premium unleaded gasoli-ne with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand. Use of unleaded fuel will
extend spark plug life and reduce
maintenance costs.

Before operating the motorcycle:
Check the fuel tank breather/over-
flow hose connection.
Check the fuel tank
breather/overflow hose for
cracks or damage, and replace it
if damaged.
Make sure that the end of the fuel
tank breather/overflow hose is
not blocked, and clean it if
necessary.
Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
