Shifting in Reverse
All Models

WARNING
Shifting to reverse mode on these snowmobiles is done by
depressing the START/RER button when the engine is run-
ning. Wait until the reverse alarm sounds and the DESS/RER
pilot lamp comes on in the dash before operating throttle to
proceed in reverse. The reverse speed of these snowmobiles
is not limited. Always proceed with caution as fast reverse
could result in loss of vehicle stability. Come to complete
stop before depressing START/RER button. Always remain
seated and apply the brake before shifting. Ensure the path
behind is clear of obstacles or bystanders before proceeding.
With the snowmobile completely stopped and engine running at idle,
press and release the START/RER button.
The DESS TM /RER TM pilot lamp will blink and a warning buzzer will
sound once every second with a half a second duration when the
snowmobile is engaged in reverse.
Apply throttle slowly and evenly. Allow drive pulley to engage then
accelerate carefully.
