GM Chevrolet Avalanche - Manual (Page 106)

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 2-40.
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 4-10.
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.
