STARTING AND OPERATING 223
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Two-Wheel Drive High Range — This range is for
normal street and highway driving on dry, hard
surfaced roads.
4H AUTO
Four-Wheel Drive Auto High Range This range
sends power to the front wheels. The four-wheel
drive system will be automatically engaged
when the vehicle senses a loss of traction. Addi-
tional traction for varying road conditions.
4H P-T
Four-Wheel Drive Part Time High Range — This
range maximizes torque to the front driveshaft,
forcing the front and rear wheels to rotate at the
same speed. This range provides additional
traction for loose, slippery road surfaces only.
N (Neutral)
Neutral — This range disengages both the front
and rear driveshafts from the powertrain. To be
used for flat towing behind another vehicle.
Refer to Recreational Towing” in “Starting And
Operating” for further information.
4L
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing the
front and rear wheels to rotate at the same
speed. This range provides additional traction
and maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
This 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.
For variable driving conditions, the 4WD AUTO
mode can be used. In this mode, the front axle
is engaged, but the vehicle's power is sent to
the rear wheels. Four-wheel drive will be auto-
matically engaged when the vehicle senses a
loss of traction. Because the front axle is
engaged, this mode will result in lower fuel
economy than the 2WD mode.
In the event that additional traction is required,
the transfer case 4H and 4L positions can be
used to lock the front and rear driveshafts
together, forcing the front and rear wheels to
rotate at the same speed. The 4H and 4L posi-
tions are intended for loose, slippery road
surfaces only and not intended for normal
driving. Driving in the 4H and 4L positions on
hard-surfaced roads will cause increased tire
wear and damage to the driveline components.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL (N) position without first
fully engaging the parking brake. The transfer
case NEUTRAL (N) position disengages both
the front and rear driveshafts from the
powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK
(or manual transmission is in gear). The
parking brake should always be applied when
the driver is not in the vehicle.
