Automatic Transfer Case
{CAUTION:
Shifting the transfer case to NEUTRAL can
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 2-36.
The transfer case buttons
are located to the left of
the instrument panel
cluster.
For four-wheel drive
vehicles with StabiliTrak
®
,
see StabiliTrak
®
System
on page 4-11.
Use these buttons to shift into and out of four-wheel drive.
You can choose among four driving settings:
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.
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 only 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.
G (4HI): Use the 4HI position when you need extra
traction, such as on snowy or icy roads or in most
off-road situations. This setting also engages your front
axle to help drive your vehicle. This is the best setting
to use when plowing snow.
5(4LO): This setting also engages your front axle
and delivers extra torque. You may never need this
setting. It sends maximum power to all four wheels.
You might choose 4LO if you are driving off-road in deep
sand, deep mud, deep snow and climbing or descending
steep hills. Four-wheel drive vehicles with StabiliTrak
®
will not engage in this mode. See StabiliTrak
®
System on page 4-11 for more information.
