FEATURES AND CONTROLS
All Wheel Drive (4X4) System
Engaging 4X4
The 4X4 switch may be turned on or off while the vehicle is moving.
4X4 will not engage until engine speed is below 3100 RPM. 4X4
remains engaged until the switch is turned off. There is no limit to the
length of time the vehicle may remain in 4X4.
If the switch is turned off while the demand drive unit is engaged, it will
not disengage until the rear wheels regain traction. Engage 4X4 before
getting into situations where maximum traction is needed. If the rear
wheels are spinning, release the throttle before switching to 4X4.
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 24 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 24 km/h
• The throttle is open (throttle is applied)
• The transmission is shifted to neutral or park
