when you ride off of established trails. Hit­ting a rock or stump, or running into wires
could cause an accident and injury.

● This snowmobile is not designed for use on

surfaces other than snow or ice. Use on dirt,
sand, grass, rocks, or bare pavement may
cause loss of control and may damage the
snowmobile.

Safety information

● Always ride with other snowmobilers when

going on a ride. You may need help if you
run out of fuel, have an accident, or damage
your snowmobile.

● Many surfaces such as ice and hardpacked

snow require much longer stopping distanc­es. Be alert, plan ahead and begin deceler­ating early. The best braking method on
most surfaces is to release the throttle and
apply the brake gently—not suddenly.

Avoid carbon monoxide poisoning

All engine exhaust contains carbon monox­ide, a deadly gas. Breathing carbon monoxide
can cause headaches, dizziness, drowsiness,
nausea, confusion, and eventually death.
Carbon monoxide is a colorless, odorless,
tasteless gas which may be present even if
you do not see or smell any engine exhaust.
Deadly levels of carbon monoxide can collect
rapidly and you can quickly be overcome and
be unable to save yourself. Also, deadly lev­els of carbon monoxide can linger for hours or
days in enclosed or poorly-ventilated areas. If
you experience any symptoms of carbon
monoxide poisoning, leave the area immedi­ately, get fresh air, and SEEK MEDICAL
TREATMENT.

● Do not run the engine indoors. Even if you

try to ventilate engine exhaust with fans or
open windows and doors, carbon monoxide
can rapidly reach dangerous levels.

● Do not run the engine in poorly ventilated or

partially enclosed areas such as barns, ga­rages, or carports.

● Do not run the engine outdoors where en-

gine exhaust can be drawn into a building
through openings such as windows and
doors.

Genuine Yamaha Accessories

Choosing accessories for your snowmobile is
an important decision. Genuine Yamaha Ac­cessories, which are available only from a
Yamaha dealer, have been designed, tested,
and approved by Yamaha for use on your
snowmobile. Many companies with no con­nection to Yamaha manufacture parts and ac­cessories or offer other modifications for
Yamaha vehicles. Yamaha is not in a position
to test the products that these aftermarket
companies produce. Therefore, Yamaha can
neither endorse nor recommend the use of
accessories not sold by Yamaha or modifica­tions not specifically recommended by
Yamaha, even if sold and installed by a
Yamaha dealer.

Maintenance and storage

● When laying the snowmobile on its side for

maintenance, use a suitable stand to keep
it in a stable and level position.

● Do not leave the snowmobile on its left side

for an extended period of time. Fuel may
leak out from the fuel breather hose.

● Do not allow anyone to stand behind the

snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken track,
track fittings, or debris thrown by the track
could be dangerous to the operator or by­standers.

● Modifications made to the snowmobile not

approved by Yamaha, or the removal of
original equipment may render your snow­mobile unsafe for use, which may cause se­vere personal injury. Modifications may
also make the snowmobile illegal to use.

● Never store the snowmobile with fuel in the

fuel tank inside a building where ignition
sources are present such as hot water and
space heaters, an open flame, sparks,

14

clothes dryers, and the like. Allow the en­gine to cool off before storing the snowmo­bile in an enclosed space.

Throttle lever

Once the engine is running cleanly, squeez­ing the throttle lever will increase the engine
speed and cause engagement of the drive
train. Regulate the speed of the snowmobile
by varying the throttle position. Because the
throttle is spring-loaded, the snowmobile will
decelerate, and the engine will return to idle
when it is released.

Throttle override system (T.O.R.S.)

EWS00041

If the T.O.R.S. is activated, make sure that
the cause of the malfunction has been cor­rected and that the engine can be operated
without a problem before restarting the
engine. Continuing to operate with a mal­function could cause loss of control or
damage.

If the throttle valves or throttle cable malfunc­tions during operation, the T.O.R.S. will be ac­tivated when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection (RS90P / RS90PLT / RST90PGT /
RST90PTF) or ignition (RST90) and limit the
engine speed to less than the clutch engage­ment speed if the throttle valves fail to return
to the idle position when the throttle lever is
released. (See page 133 for the clutch en­gagement speed.)

Multi-function meter unit

RS90P / RS90PLT / RST90PGT /
RST90PTF

The multi-function meter unit is equipped with
the following:

● a digital speedometer

● a tachometer

● an odometer

● 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 fuel level warn­ing indicator and warning light came on)

● an oil change tripmeter (which shows the

distance traveled since the periodic oil
change interval was reached)

● a clock

● warning indicators (which show engine

trouble, coolant temperature, fuel level, and
oil level warnings)

● indicator lights (which show high beam and

low coolant temperature conditions)

● a warning light (which shows warnings to-

gether with the warning indicators)

● a fuel meter (which shows the fuel remain-

ing in the fuel tank)

● a grip/thumb warmer level indicator (which

shows the grip warmer level or the thumb
warmer level)

● a display brightness control function

When the key is turned to the on position, the
tachometer needle makes one sweep, and
the low coolant temperature indicator light,
the warning light, and all segments of the
meter unit display come on and go off.

Odometer and tripmeter modes

E LO

1. Odometer/tripmeter/fuel reserve tripmeter

Pushing the “SELECT” button switches the
display between the odometer mode “ODO”
and the tripmeter modes “TRIP A” and “TRIP
B” in the following order:
ODO → TRIP A → TRIP B → ODO
If the fuel level warning indicator and warning
light come on (see page 26), the odometer
display will automatically change to the fuel
reserve tripmeter mode “TRIP F” and start
counting the distance traveled from that point.
In that case, push the “SELECT” button to
switch the display between the various trip­meter and odometer modes in the following
order:
TRIP F → ODO → TRIP A → TRIP B → TRIP
F
To reset a tripmeter, select it by pushing the
“SELECT” button, and then push the “RE­SET” button for at least 1 second. If you do not
reset the fuel reserve tripmeter manually, it
will reset itself automatically, and the display
will return to the prior mode after the snowmo­bile has been refueled and traveled 5 km (3
mi).

Oil change tripmeter

When the periodic oil change interval is
reached at the initial 800 km (500 mi), then at
every 4000 km (2500 mi) thereafter, the oil
change tripmeter and “OIL” flash alternately in
the odometer display, and the tripmeter starts

22

counting the distance traveled from that point.
When this occurs, change the engine oil as
soon as possible. (See page 87 for the oil
change procedure.)

E LO

● The oil change tripmeter will flash only

when the snowmobile is stopped.

● To return to the previous display mode,

push the “SELECT” button. To display the
oil change tripmeter again, turn the key to
the off position, then back to the on position.

After changing the engine oil, reset the oil
change tripmeter as follows.

To reset the oil change tripmeter (when the
engine oil was changed after the oil change
tripmeter appeared)

1. To display the oil change tripmeter, turn
the key to the on position.

2. Push the “RESET” button for at least 1
second while the oil change tripmeter and
“OIL” are flashing alternately in the odom­eter display. The distance traveled since
the last oil change and “OIL” will flash al­ternately in the odometer display.

3. Push the “RESET” button for approxi­mately 3 seconds. “00000” and “OIL” will
flash alternately in the odometer display 3
times, and then the display will return to
the previous display mode.
