VEHICLE WARM-UP
Before every ride, vehicle has to be warmed up as follows.
Snowmobile must be securely supported by the rear bumper using
a wide-base snowmobile mechanical stand. Track must be 100 mm
(4 in) off the ground.
Attach tether cord to operator's clothing eyelet.
Start engine and allow it to warm up two or three minutes at idle
speed.
NOTE: On models equipped with DPM-Power TEK technology, en-
gine will stop automatically after four minutes of idling and engine
temperature higher than 85°C (185°F). By depressing throttle handle
within the four minutes delay, this will reset timer for another four
minutes.
Release parking brake.

WARNING
Make sure wide-base snowmobile mechanical stand is stable.
Stay clear of the front of vehicle and the track. Do not use too
much throttle during warm-up or when track is free-hanging.
Apply throttle until drive pulley engages. Let track rotate at low
speed for several turns. The lower the vehicle temperature is the
longer vehicle warm-up should be.
Shut-off the engine and remove the wide-base snowmobile mechan-
ical stand.
Skis may be frozen on the ground. Grab both skis one at a time by
their loops and lift their front end slightly off the ground.
After restarting engine, the vehicle can be driven at low speed for
the first 2 or 3 minutes of riding. After that, it may be driven up to
the legal speed limit as per normal safety practices.
