FEATURES AND CONTROLS

Park Brake Lever (if equipped)

Always apply the service brakes before engaging or releasing the park 
brake. To help prevent the vehicle from rolling, set the park brake when 
parking the vehicle. When the park brake is set and the park brake 
indicator is illuminated, engine speed is limited. If the accelerator is 
applied, this limiting feature prevents operation, which protects the park 
brake pads from excessive wear.

Tip: This feature will not operate 

properly if the park brake 
connector or switch (under the 
hood) malfunctions or 
becomes disconnected, or if 
the switch has moved. Check 
for disconnection, then see 
your dealer or other qualified 
service person promptly if this 
feature fails to operate 
properly.

1. To set the park brake, apply 

the brakes.

2. Pull the park brake lever 

upward as far as possible.

3. To release the park brake, 

apply the brakes. Press the 
park brake release inward 
and move the lever 
downward as far as possible.

FEATURES AND CONTROLS

Rollover Protective Structure (ROPS)

The Rollover Protective Structure 
(ROPS) on this vehicle meets 
OSHA 1928.53 rollover 
performance requirements. Always 
have authorized service personnel 
or your POLARIS dealer 
thoroughly inspect the ROPS if it 
ever becomes damaged in any way.

No device can assure occupant 
protection in the event of a rollover. 
When used with seat belts and cab 
nets, the ROPS helps prevent 
occupants from being ejected from 
the vehicle. Always follow all safe 
operating practices outlined in this 
manual to avoid vehicle rollover.

WARNING! Vehicle rollover could cause severe injury or death. Always avoid 
operating in a manner that could result in vehicle rollover.

FEATURES AND CONTROLS

Electronic Power Steering (EPS)

Electronic power steering (if 
equipped) engages when the ignition 
key is turned to the ON position. EPS 
remains engaged whether the vehicle 
is moving or idle.

The EPS warning indicator briefly 
illuminates when the key is turned to 
the ON position. See page 45.

To conserve battery power, the EPS 
will shut down 5 minutes after the 
engine is stopped if the key remains 
in the ON position. The EPS warning 
indicator will illuminate to indicate 
the EPS has shut down.

If the light remains on after starting the engine, the EPS system is 
inoperative. Your POLARIS dealer can assist.

FEATURES AND CONTROLS

All Wheel Drive (AWD) System

For models equipped with a rear differential, refer to the All Wheel 
Drive/Rear Differential section beginning on page 41.

On models not equipped with a rear differential, 
the All Wheel Drive system is controlled by the 
AWD switch. When the switch is on 2X4, the 
vehicle is in two-wheel drive at all times. When 
the switch is on AWD, the vehicle is in all wheel 
drive and the 4X4 indicator in the instrument 
cluster will be on.

When in AWD, the demand drive unit will 
automatically engage any time the rear wheels lose 
traction. When the rear wheels regain traction, the 
demand drive unit will automatically disengage. 

There is no limit to the length of time the vehicle may remain in AWD.

Engaging AWD

The AWD switch may be turned on or off while the vehicle is moving. 
Initially, the vehicle's electronic system will not enable the AWD until 
the engine RPM is below 3100. Once enabled, the AWD remains 
enabled until the AWD switch is turned off. If the switch is turned off 
while the demand drive unit is moving, it will not disengage until the 
rear wheels regain traction.

Engage the AWD switch before getting into conditions where front 
wheel drive may be needed. If the rear wheels are spinning, release the 
throttle before switching to AWD.

NOTICE: Switching to AWD while the rear wheels are spinning or slipping may 

cause severe drive shaft and gearcase damage. Always switch to 
AWD while the rear wheels have traction or are at rest.
