Polaris 550 IQ Shift - Manual (Page 61)

OPERATION
Electronic Reverse (PERCt)
Electronic reverse will activate only if the engine RPM is below 4000. If
your machine is running at an altitude of over 6000 feet, adjust the igni-
tion setting as described on page 59. Always make sure the vehicle is
stopped and the engine is running at idle before shifting to reverse
NOTE: The engine will activate a misfire mode and begin to stutter after 45 sec-
onds in reverse. This feature protects the engine from overheating and
will reset when it is shifted into forward or when the engine is stopped
and restarted..
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.
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.
