Electronic Reverse (PERCt)
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 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.
Electronic reverse will activate only if the engine RPM is below 4000.
NOTICE: Engaging the starter when the engine is running WILL result in serious
engine damage, especially if the snowmobile is in reverse. Never
engage the starter when the engine is running.
