5-3 ESU00023 Throttle override system (T.O.R.S.) If the carburetor or throttle cable should malfunction dur- ing operation, the T.O.R.S. will operate when the throttle lever is released. The T.O.R.S. is designed to interrupt the ignition and keep the engine revolution speed between 2,800 and 3,000 r/min if the carburetor fails to return to idle when the lever is released. WARNING@ 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 prob- lem before restarting the engine. Be sure to use the specified spark plug and spark plug cap. Otherwise, the T.O.R.S. will not work properly. @CA-01E ÈIdle or starting ÉRun ÊTr o u b l e 1Carburetor switch 2Throttle switch 3Throttle cable 4Throttle valve aOn bOff A B C Mode SwitchIdle or startingRun Trouble Throttle switch Off On Off Carburetor switch On Off Off Engine Run RunT.O.R.S. will operateABC U8FA11.book Page 3 Thursday, April 3, 2003 4:09 PM
5-4 ESU03900 Speedometer unit The speedometer unit is equipped with the following: a digital speedometer (which shows riding speed) an odometer (which shows the total distance trav- eled) a tripmeter (which shows the distance traveled since it was last set to zero) warning indicators (which show self-diagnosis, cool- ant temperature, fuel level, and oil level warnings) a fuel meter (which shows the fuel remaining in the fuel tank) a grip/thumb warmer heat level indicator (which shows the heat level of the grip warmer or the thumb warmer) After the engine is started, the tachometer 1 makes one sweep, and the warning light 2 and all segments of the meter 3 turn on and off once. The grip warmer heat level is initially displayed for 5 seconds, then switches to the fuel meter display. Odometer and tripmeter modes Pushing the select/reset button 4 switches the display between the odometer mode “ODO” and the tripmeter mode “TRIP”. To reset the tripmeter, push the select/reset button for at least one second while the tripmeter is displayed. NOTE:@ To switch the speedometer, odometer, and tripmeter dis- plays between kilometers and miles, select the odometer mode “ODO”, and then push the select/reset button 4 for at least 10 seconds while the snowmobile is stopped. @ ESU00363 High beam indicator light The high beam indicator light 1 comes on when the high beams of the headlights are switched on. (See page 5-12 for headlight beam switch operation.) U8FA11.book Page 4 Thursday, April 3, 2003 4:09 PM
5-5 ESU03820 Fuel meter and grip/thumb warmer heat level indicator The fuel meter and grip/thumb warmer heat level indica- tor have eight segments 1 which show the amount of fuel remaining in the fuel tank, the heat level of the grip warmer, or the heat level of the thumb warmer. Fuel meter As the fuel level decreases in the fuel tank, the segments disappear until the level goes down to the last segment “E” (Empty). When this occurs, the fuel level warning indicator 2 and the warning light 3 come on. If the fuel level warning indicator and the warning light come on, fill the fuel tank at the first opportunity. NOTE:@ The snowmobile must be stopped on a level surface to obtain an accurate fuel meter reading. The fuel meter reading changes as the snowmobile moves and depend- ing on the inclination of the snowmobile. @ Grip/thumb warmer heat level indicator The grip warmer adjustment switch 1 and the thumb warmer adjustment switch 2 control the electrically heated handlebar grips and throttle lever. To raise the temperature, press each switch to “HI”. To lower the temperature, press each switch to “LO”. NOTE:@ The grip warmer indicator 3 comes on and the dis- play switches to the grip warmer heat level when the grip warmer adjustment switch is pressed. The thumb warmer indicator 4 comes on and the dis- play switches to the thumb warmer heat level when the thumb warmer adjustment switch is pressed. The grip/thumb warmer heat level is displayed for 5 seconds after releasing the grip/thumb warmer adjustment switch, then switches to the fuel meter. The top segment of the heat level indicator flashes once if the grip/thumb warmer adjustment switches are continually pressed at the maximum level. The bottom segment of the heat level indicator flashes once if the grip/thumb warmer adjustment switches are continually pressed at the minimum level. When the engine is started, the grip/thumb heat levels are set to the levels saved when the engine was stopped. @ U8FA11.book Page 5 Thursday, April 3, 2003 4:09 PM
5-6 ESU00287 Fuel level warning indicator The fuel level warning indicator indicates a malfunction- ing sensor, disconnected coupler, broken lead, or short circuit when detected by the self-diagnosis device of the snowmobile. The fuel level warning indicator 1, warning light 2, and all segments of the fuel meter 3 warn the rider of the above problems by flashing continuously. (See the table below for warning indicator, warning light and fuel meter segment flash pattern.) When this occurs, have a Yamaha dealer inspect the snowmobile as soon as possible. CA-08E ESU00377 Oil level warning indicator The oil level warning indicator 1 and the warning light 2 come on when the engine oil level is low. If the oil level warning indicator and the warning light come on, place the snowmobile on a level surface and allow it to idle for one minute. If the oil level warning indicator and the warning light go off, the engine oil level is sufficient, however it is getting low. Add engine oil as soon as possible. If the oil level warning indicator and the warning light do not go off, check the engine oil level in the oil tank (see page 6-3), and add engine oil if necessary. Warning indicator, warning light, and fuel meter segments of the fuel meter flash pattern Warning indicator, warning light, and fuel meter segment flash continuously in this pattern. : On : Off s: Second 0.5 s 3 s 12 8 0.5 s · · · U8FA11.book Page 6 Thursday, April 3, 2003 4:09 PM
5-7 ESU00360 Low coolant temperature indicator light The low coolant temperature indicator light 1 flashes when the coolant temperature is low and informs the rider that the snowmobile must be warmed up. After the engine is started, warm it up until the indicator light goes off. The snowmobile can be operated normally after the indi- cator light goes off. NOTE: When the low coolant temperature indicator light flashes, the engine control system prevents the engine speed from rising even if the throttle lever is pressed. ESU00364 Coolant temperature warning indicator If the engine overheats, the coolant temperature warning indicator 1 and the warning light 2 come on. When this occurs, stop the engine immediately and allow the engine to cool down, and then check the coolant level in the coolant reservoir. (See page 6-4.) CAUTION:@ Do not operate the engine if it overheats. @ The coolant temperature warning indicator indicates a malfunctioning sensor, disconnected coupler, broken lead, or short circuit when detected by the self-diagnosis device of the snowmobile. The coolant temperature warning indicator and warning light warn the rider of the above problems by flashing continuously. (See the table below for the warning light flash pattern.) When this occurs, have a Yamaha dealer inspect the snowmobile as soon as possible.

5-8 ESU00365 Self-diagnosis warning indicator The self-diagnosis warning indicator indicates a malfunc- tioning sensor, disconnected coupler, broken lead, etc., when detected by the self-diagnosis device of the snow- mobile. The self-diagnosis warning indicator 1 and warning light 2 warn the rider of the above problems by flashing con- tinuously. If necessary, ask a Yamaha dealer for further details. (See page 5-9 for warning indicator and warning light flash patterns.) WARNING@ If the self-diagnosis warning indicator and warn- ing light flash continuously during operation, there may be some problem with the electrical circuit, lead couplers, etc. (See page 5-9 for warn- ing indicator and warning light flash pattern num- bers 1–6.) Stop the engine and allow it to cool off. Then, check that the wire harness couplers are con- nected properly in the engine compartment. If the self-diagnosis warning indicator and warn- ing light flash after the engine has been started, note the flash pattern, and then have a Yamaha dealer inspect the snowmobile as soon as possi- ble. @ U8FA11.book Page 8 Thursday, April 3, 2003 4:09 PM
