Tow/Haul Mode
Your vehicle may be equipped with a tow/haul mode.
If so, the selector button is located on the end of
the column shift lever. You can use this feature to assist
when towing or hauling a heavy load. See Towing a
Trailer on page 4-65 for more information.
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 4-64 .
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 LOW (4LO) positions for a long time on
dry or wet pavement could shorten the life of
your vehicle's drivetrain.
When tow/haul mode is
selected the tow/haul
indicator light will
illuminate.
