ELECTRONIC REVERSE
Tundra and Skandic LT/LT E
General
These models are equipped with a Rotax Electronic Reverse (RER
TM
)
controlled by a RER button.
When the engine is running, depressing the RER button will com-
mand the engine to reverse crankshaft rotation as driving the snow-
mobile in reverse is achieved by changing the direction of rotation of
the engine, not by shifting the chaincase in reverse gear.
When depressing the RER button, the MPEM (Multi-Purpose Elec-
tronic Module) will practically slow down the engine RPM to a stop
and advance the ignition timing to cause crankshaft rotation reversing.
Engine will automatically shift into forward when starting after stop-
ping or stalling.
Shifting procedure will take place only when the engine is running.
If engine is running at a speed above 3800 RPM, the reverse function
of the RER button is cancelled.
It is recommended to warm up the engine to its normal operating
temperature before shifting.
No adjustment is needed except for high altitude. See RER MODIFI-
CATION AT HIGH ALTITUDE below.
Shifting in Reverse
WARNING
Shifting to the reverse mode on these snowmobiles is done by
depressing the RER button when the engine is running. Wait
until the reverse alarm sounds and the reverse pilot lamp
comes on in the dash before operating throttle to proceed in
reverse. The reverse speed of these snowmobiles is not limit-
ed. Always proceed with caution as fast reverse could result in
loss of vehicle stability and control. Come to complete stop
before depressing RER button. Always remain seated and ap-
ply the brake before shifting. Ensure the path behind is clear
of obstacles or bystanders before proceeding.
