Four-Wheel Drive - GMC 2007 Envoy Denali Owner's Manual

Four-Wheel Drive

If your vehicle has four-wheel drive, the engine's
driving power can be sent to all four wheels
for extra traction. To get the most satisfaction out
of four-wheel drive, you must be familiar with
its operation. Read the part that follows before
using four-wheel drive. You should use Two-Wheel
High for most normal driving conditions.
Notice: Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for an extended period of time may cause
premature wear on your vehicle's powertrain.
Do not drive on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for extended periods of time.
Automatic Transfer Case
If your vehicle has four-wheel drive, the transfer
case knob is located to the right of the steering
wheel on the instrument panel.

2 (Two-Wheel High): This setting is for
driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
It also provides the best fuel economy.
AUTO (Automatic Four-Wheel Drive): This
setting is ideal for use when road conditions are
variable. When driving your vehicle in automatic
four-wheel drive, 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 Two-Wheel High.
