Four-Wheel Drive; Front Axle Locking Feature - Chevrolet 2005 Tahoe Owner's Manual

The Tow/Haul mode also interacts with the Autoride™
feature, if your vehicle is so equipped, to enhance
the ride when trailering or with a loaded vehicle.
See Autoride™ on page 4-61.
When Tow/Haul mode is
selected the Tow/Haul
indicator light will
illuminate.

Four-Wheel Drive

If your vehicle has four-wheel drive, you can send your
engine's driving power 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.
See the appropriate text for the transfer case in your
vehicle.
Notice: Driving on clean, dry pavement in
four-wheel drive 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 for extended periods of time.

Front Axle Locking Feature

The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock is normal.
