Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
theDrivingchapter of thisOwner’s Guide.
Loaded vehicles may handle differently than unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer, provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.

Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use or install hitches that clamp onto the bumper or to the axle.
Underbody hitches are acceptable if installed properly.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.

A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may
exhibit a slight noise or vibration in tight turns with low vehicle speed.
This is normal behavior and indicates the axle is working.
PREPARING TO DRIVE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.
Your vehicle has larger tires and increased ground clearance, giving the
vehicle a higher center of gravity than a passenger car.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions such as
slower speeds and increased stopping distance should be taken when
driving a heavily loaded vehicle.
Vehicle stability and handling
The risk of a rollover crash increases as the number of people and load
in the vehicle increase. This increased risk occurs because the passenger
weight and load raises the vehicle’s center of gravity and causes it to

•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
ADVANCETRACWITH ROLL STABILITY CONTROL (RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
The AdvanceTracwith RSC system provides stability and traction
enhancement for certain driving situations when driver assistance is
needed. It helps your vehicle maintain traction, when driving on slippery
and/or hilly road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled by momentarily reducing engine
power and rapidly applying the anti-lock brakes. The system is a driver
aid which makes your vehicle easier to handle primarily on snow and
ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTracwith RSC system off by pressing the AdvanceTrac
with RSC button. This will allow your tires to “dig” for traction.
If the AdvanceTracwith RSC system is activated excessively in a short
period of time, the brake portion of the system will shut down to allow
the brakes to cool down. A limited AdvanceTracwith RSC function
using only engine power reduction will still help control the wheels from
over-spinning. When the brakes have cooled down, the system will again
function normally. Anti-lock braking is not affected by this condition and
will function normally during the cool-down period.
The AdvanceTracwith RSC system enhances your vehicle’s stability
during maneuvers that require all available tire traction, like in
wet/snowy/icy road conditions and/or when performing emergency
maneuvers. In an emergency lane-change, the driver will experience
better overall vehicle traction, and have better control of the vehicle.
The AdvanceTracwith RSC system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
AdvanceTracwith RSC will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.
Driving conditions which may activate AdvanceTracwith RSC system
include:
•Taking a turn too fast.
•Maneuvering quickly to avoid an accident, pedestrian or obstacle.
•Hitting a patch of ice.
