FEATURES AND CONTROLS
All Wheel Drive System
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 3100. 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.
Active Descent Control (ADC) System
The ADC system allows engine braking to all four wheels when the
vehicle descends a hill or incline. Always move the 4X4 switch to ADC
4X4 before ascending or descending a hill.
Engaging Active Descent Control
The ADC system will automatically engage when all four of the follow-
ing conditions occur:
The 4X4 switch must be in the ADC 4X4 position
Vehicle speed must be 15 mph (25 km/h) or less
The throttle must be closed (throttle lever released)
The transmission must be in gear (high, low or reverse)
Disengaging Active Descent Control
The ADC system will automatically disengage if at least one of the fol-
lowing conditions occur:
The 4X4 switch is moved out of the ADC 4X4 position
Vehicle speed exceeds 15 mph (25 km/h)
The throttle is open (throttle is applied)
The transmission is shifted to neutral or park
