Altitude Setting; Important Notes - Polaris IQ 2007 Service Manual

NOTE: If the engine stops running or is shut off
while in reverse. The engine will start in forward
gear.
FORWARD OPERATION
1. If unit was operated in reverse, ensure that the path ahead
is clear, and push an hold the reverse button for 1 second
and then release the button. The engine will now
automatically change direction form reverse to forward
and the reverse light on the instrument panel will stop
flashing.
NOTE: When servicing clutches, ensure that the
vehicle is in forward gear. If not damage to the
driven clutch may occur when removing the belt.

Altitude Setting

If your engine is carbureted, you can adjust the elevation setting
of the Polaris electric reverse control (PERC). If your engine is
a Cleanfire system, this is automatically done through the
engine controller unit (ECU), and you do not need to do any
setting.
At higher elevations over 6000 ft (1829m), the engine requires
a different ignition RPM setting to improve the operation of the
reverse system.
To set the altitude settings:
1. With the engine running, push and hold the reverse button
for 5 - 6 seconds and then release the button.
2. The reverse light will flash rapidly on the instrument panel.
3. You have now set the PERC system to the higher elevation
setting.
4. To go back to the low elevation setting repeat step 1. The
reverse light will flash slowly indicating that the system is
now in the lower elevation setting.
NOTE: The elevation setting will be set in the
memory (engine running or not) until it is changed.

Important Notes

• Max RPM for shifting into reverse = 4000 RPM
• Max RPM for operating in reverse = 6000 RPM
• Engine must first reach 900 RPM at start up before the
reverse system can be used. The system works between
900 and 4000 RPM.
• If the button is pushed above 4000 RPM the system is
bypassed and nothing will happen.
• Flashing light on the instrument panel indicates that the
system is in reverse. On carbureted units a slow flash
indicates that the system is set for low elevation, and a
Battery and Electrical Systems
fast flash indicates the system is set up for high
elevation. Push and hold the reverse button for longer
than 5 seconds to toggle back and forth from high and
low elevation settings. On Cleanfire units this is
automatically done through the engine controller unit
(ECU).
• Elevation above 6000 ft (1829m) requires a different
timing curve to eliminate a "kick-back" effect.
• If engine is shut off or dies in forward or reverse gear,
the engine when started will automatically be in
forward gear.
• When servicing clutches, ensure that the vehicle is in
the forward gear.
