FOUR-WHEEL DRIVE
OPERATION
Four-Position Transfer Case
• The transfer case provides four mode
positions.
• Two-wheel drive high range (2H)
• Four-wheel drive high range (4H)
• NEUTRAL (N)
• Four-wheel drive low range (4L)
• This transfer case is intended to be
driven in the 2H position for normal
street and highway conditions, such
as dry, hard-surfaced roads.
• When additional traction is required,
the 4H and 4L positions can be used
to lock the front and rear driveshafts
together.
• When operating your vehicle in 4L, do
not exceed 25 mph (40 km/h).
Shifting Procedure
• Shifting between 2H and 4H can be
made with the vehicle stopped or in
motion at speeds up to 55 mph
(88 km/h).
• Shifting between 2H or 4H and 4L can
be made with the vehicle rolling at 2
to 3 mph (3 to 5 km/h).
Five-Position Transfer Case
• This electronically shifted transfer
case provides five mode positions:
• Two-wheel drive high range (2WD)
• Four-wheel drive automatic range
(4WD AUTO)
• Four-wheel drive lock range (4WD
LOCK)
• Four-wheel drive low range (4WD
LOW)
• NEUTRAL (N)
• This electronically shifted transfer
case is designed to be driven in the
two–wheel drive position (2WD) or
four-wheel drive position (4WD AUTO)
for normal street and highway
conditions on dry, hard-surfaced
roads.
• Driving the vehicle in 2WD will have
greater fuel economy benefits as the
front axle is not engaged in 2WD.
Shifting Procedure
• Shifting between 2H and 4WD AUTO
or 4WD LOCK can be made with the
vehicle stopped or in motion.
• Shifting between 2H or 4H and 4L can
be made with the vehicle stopped or
rolling at 2 to 3 mph (3 to 5 km/h).
NOTE: It is preferred to have the engine
running and the vehicle moving at 2 to
3 mph (3 to 5 km/h).
WARNING!
You or others could be injured if you
leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the
parking brake. The transfer case
NEUTRAL position disengages both
the front and rear driveshafts from
the powertrain and will allow the
vehicle to move regardless of the
transmission position. The parking
brake should always be applied when
the driver is not in the vehicle.
