How Your Vehicle Differs From Other Vehicles
WARNING: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 are notdesigned 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.
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Driving Off-Road With Truck and Utility Vehicles
Note: On some 4WD models, the initial shift from two-wheel drive to
four-wheel drive while the vehicle is moving can cause some momentary
clunk and ratcheting sounds. This is the front drivetrain coming up to
speed and the automatic locking hubs engaging and is not cause for
concern.
Note: Your vehicle may be equipped with a front air dam that can
become damaged (due to reduced ground clearance) when taking your
vehicle off-road. This air dam can be taken off by removing two bolts.
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.

If you do stall out, do not try to turn around because you might roll over.
It is better to back down to a safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
they aren’t turning, you won’t be able to steer. The front wheels have to
be turning in order to steer the vehicle.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
pump the brakes.
Driving on snow and ice
WARNING: If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.

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.

GENERAL INFORMATION
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, the brake linings may be
worn out. Have them inspected by an authorized dealer. If your vehicle
has continuous vibration or shudder in the steering wheel while braking,
have your vehicle inspected by an authorized dealer.
Note: Brake dust may accumulate on the wheels, even under normal
driving conditions. Some dust is inevitable as the brakes wear and does
not contribute to brake noise. See the Vehicle Carechapter for wheel
cleaning instructions.
See theInstrument Cluster chapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomes stuck or entrapped, apply
steady and firm pressure to the brake pedal to slow your vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to park
(P) and apply the parking brake. Inspect the accelerator pedal and the
area around it for any items or debris that may be obstructing its
movement. If none are found and the condition persists, have your
vehicle towed to the nearest authorized dealer.
Anti-Lock Brake System
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking. This lamp momentarily illuminates when you turn the ignition
on. If the light does not illuminate during start-up, remains on
or flashes, the anti-lock brake system may be disabled. Have
the system checked by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still effective.
If the brake warning lamp illuminates when you release the
parking brake, have the system checked by an authorized
dealer.

HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the risks when:
•You drive too closely to the vehicle in front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
PARKING BRAKE
WARNING: Always set the parking brake fully and make sure
that the transmission is securely latched in park (P).
To set the parking brake, press the parking brake pedal down until the
pedal stops.
The brake warning lamp will illuminate and will remain illuminated until
the parking brake is released.
To release, pull the brake release lever located at the lower left side of
the instrument panel.
HILL START ASSIST
WARNING: The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and shift the transmission into park (P).
WARNING: You must remain in the vehicle once you have
activated the hill start assist feature.
WARNING: During all times, you are responsible for controlling
the vehicle, supervising the hill start assist system and
intervening, if required.
WARNING: If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is active,
the hill start assist feature will be deactivated.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; this
may include reduced performance or a false activation.
WARNING: To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING: This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING: Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note: Keep the sensors (located on the bumper/fascia) free from snow,
ice and large accumulations of dirt. If the sensors are covered, the
system’s accuracy can be affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note: If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to the MyKey®chapter.
Note: When a trailer is connect to your vehicle, the Rear Sensing System
may detect the trailer and provide warnings. It is suggested that the
driver disables the Rear Sensing System when a trailer is connected to
your vehicle to prevent these warnings.
The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.

Using the Systems
BLIS® turns on when the engine is started and the vehicle is driven
forward above 3 mph (5 km/h); it remains on while the transmission is in
D (Drive) or N (Neutral). If shifted out of D (Drive) or N (Neutral), the
system enters CTA mode. Once shifted back into D (Drive), BLIS® turns
back on when the vehicle is driven above 3 mph (5 km/h).
Note:BLIS® does not function in R (Reverse) or P (Park) or provide
any additional warning when a turn signal is on.
CTA detects approaching vehicles from up to 45 feet (14 meters) away
though coverage decreases when the sensors are blocked. Reversing
slowly helps increase the coverage area and effectiveness.
WARNING: To help avoid personal injury, NEVER use the CTA
system as a replacement for using the interior and exterior
mirrors and looking over your shoulder before backing out of a parking
space. CTA is not a replacement for careful driving.
In this first example, the left sensor is only partially obstructed; zone
coverage is nearly maximized.

System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving.
Note: It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning will appear in the information
display and the alert indicator illuminates in the appropriate mirror(s).
The information display warning can be cleared but the alert indicator
remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key from on to off, then back on. If the blockage is still present
after the key cycle, the system senses again that it is blocked after
driving in traffic.

Reasons for messages being displayed
The radar surface is
dirty or obstructed Clean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructed Drive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signals No action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS®:
• Certain maneuvering of vehicles entering and exiting the blind zone.
• Vehicles passing through the blind zone at very fast rates.
• When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
• Adjacently parked vehicles or objects obstructing the sensors.
• Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
• Driving in reverse faster than 3 mph (5 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If you connected a trailer to your vehicle the BLIS® system may
detect the trailer causing a false alert. To avoid false alerts you may want
to turn the BLIS off manually.
There may be certain instances when either the BLIS® or CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.
