TIPBe sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.
When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
one after the other and then disap-
pear, in order to test the electrical
circuit.
For the UK, the distance traveled
is displayed in miles and the tem-
perature reading is displayed in
°C.
For other countries, the distance
traveled is displayed in kilometers
and the temperature reading is
displayed in °C.Odometer and tripmeter modes
Pushing the “SELECT” button switch-
es the display between the odometer
mode “Odo” and the tripmeter modes
“Trip” in the following order:
Odo → Trip 1 → Trip 2 → OdoWhen approximately 2.0 L (0.53 US
gal, 0.44 Imp.gal) of fuel remains in the
fuel tank, the bottom segment of the
fuel meter will start flashing, and the
display will automatically change to the
fuel reserve tripmeter mode “Trip F”
and start counting the distance trav-
eled from that point. In that case, push-
ing the “SELECT” button switches the
display between the various tripmeter
and odometer modes in the following
order:
Trip F → Trip 1 → Trip 2 → Odo → Trip
F
To reset a tripmeter, select it by push-
ing the “SELECT” button until “Trip” or
“Trip F” , push the “RESET” button for
at least one second. If you do not resetthe fuel reserve tripmeter manually, it
will reset itself automatically and the
display will return to the prior mode af-
ter refueling and traveling 5 km (3 mi).
TIPThe display cannot be changed back
button.Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. The display segments
of the fuel meter disappear towards
“E” (Empty) as the fuel level decreases.
When the fuel level reaches the bottom
segment near “E”, the bottom segment
will flash. Refuel as soon as possible.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with
changes in the weather and engine
load. If the top segment and coolant
temperature “C” “H” indicator flash,
stop the vehicle and let the engine

transponder interference. If this error
appears, try the following.1. Use the code re-registering key to
start the engine.TIPMake sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.

3. Push the “SELECT” button, and
the minute digits will start flashing.
4. Push the “RESET” button to set
the minutes.
5. Push the “SELECT” button and
then release it to start the clock.Ambient temperature display
This display shows the ambient tem-
perature from –9 °C to 50 °C in 1 °C in-
crements. The temperature displayed
may vary from the ambient tempera-
ture.
The icy road warning indicator “ ” will
flash when the temperature is below 4
°C.
TIPIf the ambient temperature falls
below –9 °C, a lower temperature
than –9 °C will not be displayed.
If the ambient temperature climbs
above 50 °C, a higher temperature
than 50 °C will not be displayed.
