CONTROLS/INSTRUMENTS/EQUIPMENT
5) DESS Post
The DESS key must be securely
snapped on its post to allow vehicle
operation.
Pulling the DESS key off its post shuts
the engine off.
WARNING
Always attach the tether cord eye-
let to clothing before starting the
engine.
DESS (Digitally Encoded Security
System)
The tether cord cap (DESS key) is dig-
itally encoded to provide you and your
snowmobile with the equivalent se-
curity of a conventional lock key and it
shuts off the engine preventing snow-
mobile to runaway if the operator falls
off the vehicle accidently.
The DESS key provided with your
snowmobile contains an electronic
chip which features a unique perma-
nently memorized digital code. Your
authorized SKI-DOO dealer programs
this key in the ECM (Engine Control
Module) of your snowmobile to allow
engine operation above 3000 RPM if
and only if this unique code has been
read after engine starting.
If another DESS key is installed, the
engine will start but will not reach drive
pulley engagement speed to move ve-
hicle.
Make sure the DESS key is free of dirt
or snow.

We recommend the purchase of ad-
ditional keys from your authorized
SKI-DOO dealer. If you have more than
one DESS-equipped SKI-DOO snow-
mobile, each can be programmed by
your authorized SKI-DOO dealer to ac-
cept the other vehicles keys.
