Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake steadily. Do not
pump the brakes. Refer to theBrakessection of this chapter for
additional information on the operation of the Anti-lock Brake System
(ABS).
Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction or wheel and tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac® system. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac®
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTrac® sensors.
Reducing the effectiveness of the AdvanceTrac® system could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING: Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac® system is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death. If
your AdvanceTrac® system activates, SLOW DOWN.
The AdvanceTrac® with Roll Stability Control™ system helps you keep
control of your vehicle when on a slippery surface. The electronic
stability control portion of the system helps avoid skids and lateral slides
and roll stability control helps avoid a vehicle rollover. The traction
control system helps avoid drive wheel spin and loss of traction. See the
Traction Control chapter for details on traction control system
operation.

WARNING:Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
Your vehicle is equipped with an electric power-assisted steering system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, steering messages may appear
in the information display.
Steering Tips
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

AUTO LEVELING SUSPENSION SYSTEM (if equipped)
The automatic leveling suspension system is designed to improve ride,
handling and general vehicle performance during:
•Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
• Towing
This system keeps the rear of your vehicle at a constant level through a
hydraulic pump inside each rear shock. Depending on the payload or
road surface conditions it will take approximately 2 miles (3.2 km) for
the leveling to complete.
If the loaded vehicle is not moved for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if a trailer is left attached to the parked vehicle for long periods
of time. You must drive your vehicle in order to re-level the suspension.
If a self-equalizing hitch is being used, your vehicle should be drive
approximately 2 miles (3.2 km) with the trailer prior to adjusting
(leveling) the hitch.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING: Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of your vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note: For information on electrical items such as fuses or relays, see the
Fuses chapter.
The load capacity of your vehicle is designated by weight not volume.
You may not necessarily be able to use all available space when loading
your vehicle or trailer.
Towing a trailer places extra load on the engine, transmission, axle,
brakes, tires, and suspension. Inspect these components before, during
and after towing.
Load Placement
To help minimize how trailer movement affects your vehicle when
driving:
• Load the heaviest items closest to the trailer floor.
• Load the heaviest items centered between the left and right side
trailer tires.
• Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
• Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward your vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. You can
find more information about proper trailer loading and setting your
vehicle up for towing under Load limitin theLoad Carrying chapter.
You can also find information in the RV and Trailer Towing Guide
available at your authorized dealer.

The standard integrated hitch has two ratings depending on mode of
operation:
•Weight-carrying mode requires a draw bar and hitch ball. The draw
bar supports all the vertical tongue load of the trailer.
• Weight-distributing mode requires an aftermarket weight-distributing
system, which includes draw bar, hitch ball, spring bars and snap-up
brackets. This system distributes the vertical tongue load of the trailer
between the truck and the trailer.
Mode Maximum trailer
weight Maximum tongue
weight
Weight-carrying 6300 lb (2857 kg) 630 lb (285 kg)
Weight-distributing 9000 lb (4082 kg) 900 lb (408 kg)
Note: These are hitch ratings only. Actual vehicle ratings are dependent
on engine, transmission and axle combinations.
Weight-distributing Hitch – Vehicles without Automatic Leveling
Suspension
WARNING: Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park your vehicle, without the trailer, on a level surface.
2. Measure the height of the top of your vehicle’s front wheel opening on the fender. This is H1.
3. Attach the trailer to your vehicle without the weight-distributing bars connected.
4. Measure the height of the top of your vehicle’s front wheel opening on the fender a second time. This is H2.
5. Install and adjust the tension in the weight distributing bars so that the height of the front fender is approximately halfway between H1
and H2.
6. Check that the trailer is level or slightly nose down toward your vehicle. If not, adjust the ball height accordingly and repeat
Steps 2–6.
Once the trailer is level or slightly nose down toward the vehicle:
• Lock the bar tension adjuster in place.

•Check that the trailer tongue securely attaches and locks onto the
hitch.
• Install safety chains, lighting, and trailer brake controls as required by
law or the trailer manufacturer.
Weight-distributing Hitch – Vehicles with Automatic Leveling
Suspension
WARNING: Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.
Note: If you do not move the loaded vehicle for approximately 12 hours,
the leveling system may bleed down to a lower height. This can be
especially apparent if you leave a trailer attached to the parked vehicle
for long periods. You must drive your vehicle in order to re-level the
suspension.
When connecting a trailer to a vehicle with automatic leveling suspension
using a weight-distributing hitch, always use the following procedure:
1. Load the interior of the vehicle to a weight similar to that which you intend to carry when towing. This includes things such as passenger
weight and cargo.
2. Drive the vehicle for approximately 2 miles (3 kilometers) to re-level the suspension.
3. Park your vehicle, without the trailer, on a level surface.
4. Measure the height to the top of your vehicle’s front wheel opening on the fender. This is H1.
5. Attach the trailer to your vehicle without the weight-distributing bars connected.
6. Make sure you securely attach and lock the trailer tongue to the hitch.
7. Install safety chains, lighting, and trailer brake controls as required by law or the trailer manufacturer.
8. Drive the vehicle and trailer at 20–25 mph (32–40 km/h) for approximately 2 miles (3 kilometers) to re-level the suspension.
9. Park your vehicle and trailer on a level surface.
10. Measure the height to the top of your vehicles front wheel opening on the fender a second time. This is H2.
