OPERATION

Track Warm-Up

Follow these steps to ensure proper warm-up of the engine, drive train 
and track.

1. Use an appropriate stand to securely support the rear of the snow-

mobile at the rear bumper. The track should be approximately 4” 
(10 cm) off the ground.

2. Start the engine and allow it to warm up two to three minutes.

3. Depress the throttle abruptly and allow the track to rotate several 

revolutions.

Tip: It will take longer to warm up the track sufficiently during colder outdoor 

temperatures.

4. Release the throttle, apply the brakes, shut off the engine and lower 

the snowmobile to the ground.

5. Grasp the skis by their front loops and move them from side to side 

to loosen snow and ice.

OPERATION

Engine Stop Switch

Push down on the engine stop switch to 
ground out the ignition and stop the 
engine quickly. Pull the switch up to the 
RUN position to allow restarting.

Throttle Safety Switch

The throttle safety switch is designed to limit engine speed to 2400 
RPM whenever all pressure is removed from the throttle lever and the 
throttle cable or throttle valves do not return to the normal closed posi-
tion. If the throttle lever is depressed with a throttle valve error, the Mal-
function Indicator Lamp will come on and vehicle speed will be limited 
to 18 MPH (29 km/h).

See page 38 for more information about conditions that will cause vehi-
cle speed and engine speed to be limited.

WARNING! Operating the snowmobile with a faulty throttle safety switch can 
result in serious injury or death in the event of an accident. If the throttle safety 
switch does not limit engine speed to 2400 RPM when all pressure is removed 
from the throttle lever during a throttle malfunction, immediately push down the 
engine stop switch. Do not start the engine again until the malfunction has been 
corrected by your dealer.

This four-stroke snowmobile has a self-diagnostic check of the throttle 
safety switch. The switch operation is checked through the engine con-
trol unit for correct operation. If a defective switch is detected by the 
self diagnostics system, the MIL will illuminate. Take your snowmobile 
to an authorized POLARIS dealer for diagnosis and repair if the MIL is 
illuminated.

OPERATION

Throttle Lever

WARNING! An improperly functioning throttle lever may cause erratic 
snowmobile behavior and loss of control, which could result in serious injury or 
death. If the throttle lever does not work properly, DO NOT start the engine.

If the engine speed limits at 2400 RPM when the throttle lever is 
released:

1. Turn the ignition switch to OFF.

2. Visually inspect the throttle cable and throttle body to determine 

what caused the safety switch to activate.

3. Test the throttle lever by compressing and releasing it several times. 

The lever and cable must return to the idle position quickly and 
completely.

4. If the throttle lever operates properly, turn the ignition switch on and 

go through normal starting procedures.

5. If the engine doesn't start, take the snowmobile to an authorized 

POLARIS dealer for service.

Tip: Excessive freeplay in the throttle cable may cause the safety switch to acti-

vate, preventing the engine from starting. If this occurs, return the snowmo-
bile to an authorized POLARIS dealer for service.

Turbo Noise (Turbo models)

Under some conditions, when the throttle lever is released the boost 
pressure dump valve will release pressure, and you may hear the sound 
of escaping air. This is a normal occurrence on turbo-charged models.

OPERATION

Electronic Reverse (PERC 4)

Electronic reverse will activate only when the vehicle is stopped and 
engine speed is below 2500 RPM. Maximum vehicle speed when oper-
ating in reverse will be approximately 12 MPH (19 km/h).

WARNING! Improper reverse operation, even at low speeds, may cause loss of 
control, resulting in serious injury or death. Damage will occur to the gearcase or 
transmission if shifting is attempted when the engine is operating above idle 
speed.

• Shift to or from reverse only when the snowmobile is stopped and when 

engine speed is at idle.

• Look behind the snowmobile before and while backing.

• Avoid sharp turns.

• Apply throttle slowly.

NOTICE: Engaging the starter when the engine is running WILL result in serious 

engine damage, especially if the transmission is in reverse. Never 
engage the starter when the engine is running.

Engaging Reverse

1. Stop the snowmobile and 

leave the engine idling.

2. Make sure the area behind 

your snowmobile is clear.

3. Push the yellow reverse but-

ton on the left-hand control 
for one second, then release.

Tip: A reverse light on the instrument panel will indicate that the transmission is 

in reverse.

4. Apply the throttle slowly to make sure the transmission is in 

reverse.

Tip: If the engine stops running, the transmission will be in forward gear when 

it's restarted.
