OPERATION

Electronic Reverse (PERCt)

Electronic reverse will activate only if the engine is below 4000 RPM. If 

your machine is running at an altitude of over 6000 feet, adjust the igni-

tion setting as described on page 62. Always make sure the vehicle is 

stopped and the engine is running at idle before shifting to reverse.

WARNING! Improper reverse operation, even at low speeds, may cause loss of 

control, resulting in serious injury or death. Damage will occur to the chaincase 

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 vehicle before and while backing.
• Avoid sharp turns.
• Apply throttle slowly.

Engaging Reverse

1. Stop the snowmobile and leave the engine idling.
2. Make sure the area behind your vehicle is clear.
3. Push the yellow reverse button on the left-hand control for one sec-

ond, then release. The engine will automatically reduce RPM and 

start a reverse rotation. A flashing 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: The maximum engine RPM will be 6000 when in reverse. 
Tip: If the engine stops running, the snowmobile will be in forward gear when it's 

restarted.

OPERATION

Electronic Reverse (PERCt)

Disengaging Reverse

1. Stop the snowmobile and leave the engine idling.

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.

2. Push the yellow reverse button for one second and release. The 

engine will slow and begin to rotate forward. The light on the 

instrument panel will shut off.

3. Apply the throttle slowly to make sure the transmission is in for-

ward.

Ignition Altitude Setting

At higher altitudes (above 6000 feet), the engine will require a different 

ignition setting to improve the success of the reverse system. To set for a 

higher altitude, start the engine and hold the button down until the light 

on the instrument panel flashes rapidly, then release the button.
To set the reverse for lower elevations, continue holding the button 

down until the reverse indicator light blinks slowly. Once set, it’s stored 

in memory until changed, whether the machine is running or not.

OPERATION

Towing

Do not use the front bumper to pull or drag the snowmobile. The front 

bumper is not designed for this type of use and may detach from the 

vehicle if force is applied.
For your safety, do not attempt to using the tow hitch until you’ve read 

the following warnings and understand the proper hitch functions.

WARNING! Objects towed with a rope have no braking power and can easily 

collide with the rear of the snowmobile or other objects, resulting in serious 

injury or death. DO NOT tow toboggans, sleds, saucers, or any type of vehicle 

with a rope. 

Only a stiff metal pole connecting the towed object and the tow hitch on 

the snowmobile should be used. If passengers are to be towed on a 

toboggan or sled, make sure the pole is at least four feet (1.2 meters) 

long to prevent any possibility of contact between the snowmobile’s 

track and a person riding in the towed object.
Braking distances increase when towing loads. Slow down to maintain 

control of the snowmobile.
If the snowmobile becomes inoperable and must be towed, and if it isn’t 

possible to use a rigid tow bar, attach the tow rope to the ski spindles 

(not to the ski loops) to prevent damage to the steering components. 

Remove the drive belt before towing, and have a rider on the towed 

snowmobile to operate the brake and steering when necessary.

NOTICE: Towing a disabled snowmobile with the drive belt in place can result in 

serious damage to the engine and drive system. Always remove the 

drive belt from a disabled snowmobile before towing.

MAINTENANCE

Emission Control Information

Any qualified repair shop or qualified person may maintain, replace, or 

repair the emission control devices or systems on your snowmobile.

Emission Control Label

Your snowmobile is equipped at the time of sale with an emission con-

trol information (ECI) label and a factory-installed emissions informa-

tion hang tag. These items are required by U.S. Environmental 

Protection Agency regulations. The ECI label is permanently affixed to 

either the right side of the tunnel or the engine recoil cover. The ECI 

label should not be removed, even after you purchase the snowmobile. 

You may remove the factory-installed emissions information hang tag, 

which is intended solely for your use in making a purchasing decision.

Emission Control Maintenance Requirements

Your snowmobile is certified to operate on gasoline with a minimum 

octane level of 87 (R+M)/2. If your snowmobile is equipped with a 

check engine light and it comes on, you must take your snowmobile to a 

qualified dealer for diagnostic service. Specifications and adjustments 

for engine tune-ups are located in the Service Manual, which is avail-

able to your qualified service technician. Reverse (if equipped) must not 

be engaged during engine tune-ups.

Owner's Responsibilities

Please read the Snowmobile Engine Emissions Limited Warranty, and 

read the maintenance section of your owner's manual. You are responsi-

ble for ensuring that the specified maintenance is performed. Polaris 

recommends that you contact an authorized Polaris dealer to perform 

any service that may be necessary.
