OPERATION
Reverse Operation
Electronic Reverse (PERCt)
Electronic reverse will activate only if the engine is below 4000 RPM
(3000 RPM on fan cooled models). If your machine is running at an
altitude of over 6000 feet, adjust the ignition setting as described below
(Altitude Settings). Always make sure the vehicle is stopped and that
the engine is running at idle before shifting to reverse.
1. Make sure the area behind your snowmobile is clear.
2. Push the yellow reverse button on the left-hand control for one
second, 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 machine is in reverse.
3. Slowly apply the throttle until movement starts to ensure the
machine is in reverse.
NOTE: If the engine stops running, the snowmobile will be in forward
gear when it’s restarted.
NOTE: The engine RPM when in reverse is limited to:
Maximum RPM Model
5000 Trail Touring/Trail Touring Deluxe
5500 Indy 340 Touring
6000 All other Touring models/WideTrak
Misfire Mode (Fan Cooled Models)
Air flow on fan cooled models is limited during reverse operation due
to reverse operation of the fan. After 45 seconds in reverse, the engine
will default into the misfire mode to prevent engine overheating.
Disengaging Reverse
Push the yellow reverse button on the left-hand control for one second
and release. The engine will slow and and begin to rotate forward.
The light on the instrument panel will shut off. Make sure the area
around your vehicle is clear and apply throttle slowly until you’re sure
the machine is in forward gear.
Altitude Settings
At altitudes above 6000 feet, engines require different ignition settings
to improve the success of the reverse system. A new setting is stored
in memory until changed, whether the machine is running or not. To
set for a higher altitude, start the engine and press the reverse button
until the light on the instrument panel flashes rapidly, then release. To
set the reverse for lower elevations, continue pressing the button until
the indicator light blinks slowly.
