6) Reverse Button
Some models are equipped with a Rotax Electronic Reverse (RER
TM
)
controlled by a reverse button.
General
Driving in reverse is achieved by changing the direction of engine ro-
tation.
Shifting in reverse is an electronic operation consisting of a control
module that modifies the ignition timing of the engine.
When depressing the reverse button, a signal will slow down the en-
gine RPM enough to modify the ignition timing advance. This reverses
crankshaft rotation.
Engine will automatically shift into forward when starting after stop-
ping or stalling.
Shifting procedure will take place only when the engine is running.
It is recommended to warm up the engine to its normal operating
temperature before shifting.
Shifting in Reverse
With the snowmobile completely stopped and engine running at idle,
press and release the reverse button.
The DESS
TM
indicator lamp will blink and a warning buzzer will sound
when the snowmobile is engaged in reverse.
Apply throttle slowly and evenly. Allow drive pulley to engage then
accelerate carefully.
Shifting in Forward
With the snowmobile completely stopped and engine running at idle,
press and release the reverse button.
DESS indicator lamp and warning buzzer will stop.
Apply throttle slowly and evenly. Allow drive pulley to engage then
accelerate carefully.
WARNING
These snowmobiles are capable of a fast reverse. Always remain
seated and apply the brake before shifting. Come to a complete
stop then push reverse button. Ensure the path behind is clear
of obstacles or bystanders. Fast reverse could result in loss of
stability.
