FEATURES AND CONTROLS
ALL WHEEL DRIVE SYSTEM
The All Wheel Drive system is controlled by the Drive Line switch.
4X4 MODE
When the switch is on 4X4, the ATV is four-wheel drive, and the 4X4 indicator
icon in the instrument cluster display will be visible.
When in 4X4, 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 4X4. The vehicle
automatically engages 4X4 when operating in reverse if the switch is set to
either 4X4 position.
2X4 MODE
When the switch is on 2X4, the ATV is in two-wheel drive at all times.
ENGAGING 4X4
The 4X4 switch may be turned on or off while the vehicle is moving. Initially, the
vehicle's electronic system will not enable 4X4 until the engine RPM is below
3000. Once enabled, 4X4 remains enabled until the 4X4 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 4X4 switch before getting into conditions where front wheel drive
may be needed. If the rear wheels are spinning, release the throttle before
switching to 4X4.
NOTICE
Switching to 4X4 or ADC 4X4 while the rear wheels are spinning may cause
severe drive shaft and gearcase damage. Always switch to 4X4 or ADC 4X4
while the rear wheels have traction or are at rest.
