AWD Control Switch (Three–Position)
This electronically shifted transfer case provides three
mode positions:
• All-wheel drive automatic range (AWD AUTO)
• All-wheel drive low range (LOW RANGE)
• Neutral (NEUTRAL)
This electronically shifted transfer case is designed to be
driven in the AWD AUTO position for normal street and
highway conditions on dry hard surfaced roads.
For variable driving conditions, the AWD AUTO mode
can be used. In this mode, the front axle is engaged, but
the vehicle's power is sent to the rear wheels. All-wheel
drive will be automatically engaged when the vehicle
senses a loss of traction.
When additional traction is required, the transfer case
LOW RANGE position can be used to lock the front and
rear driveshafts together forcing the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the AWD Control Switch to the desired position.
Refer to "Shifting Procedure" for specific shifting instruc-
tions. The LOW RANGE position is designed for loose,
slippery road surfaces only. Driving in the LOW RANGE
position on dry hard surfaced roads may cause increased
tire wear and damage to the driveline components.
