You can choose among four driving settings:
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle
in AUTO 4WD, the front axle is engaged, but the
vehicle's power is sent to the rear wheels. When the
vehicle senses a loss of traction, the system will
automatically engage four-wheel drive. Driving in this
mode results in slightly lower fuel economy than 2HI.
h
(2HI): This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two-wheel drive. This setting also provides the
best fuel economy.
G
(4HI): Use 4HI when you need extra traction, such
a on snowy or icy roads or in most off-road situations.

your vehicle. This is the best setting to use when
plowing snow.

and delivers extra torque. You may never need 4LO.

choose 4LO if you are driving off-road in deep sand,
deep mud, deep snow and climbing or descending

cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See Parking Brake on
page 2-48.
NEUTRAL: Shift the vehicle's transfer case to
