Security System (Ignition Lock System)
Your snowmobile has an optional security function that can be activated
by an authorized POLARIS dealer. If you have this feature activated,
you can lock the ignition to prevent unauthorized use when leaving the
snowmobile unattended. A locked system will limit engine speed to
3000 RPM, which prevents clutch engagement, and the snowmobile
will not move when throttle is applied.
If you wish to use this system, see page 37 of the Instrument Cluster
section for security system activation and operating instructions.
