Front Axle Locking Feature
The front axle locks and unlocks automatically when

lock or unlock is normal.
The tow/haul mode also interacts with the AutorideTM
feature,
if your vehicle is so equipped, to enhance
the ride when trailering or with a loaded vehicle. See
AutorideTM on page 4-58.
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 in the 4-WHEEL HIGH (4HI) or
4-WHEEL
