USING FOUR-WHEEL DRIVE
WARNING
For important information regarding
safe operation of this type of vehicle,
see General Information in the Wheels and
Tires chapter. Note:
Do not use 4X4 mode on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces.
Your four-wheel drive vehicle features the
heavy-duty Control Trac® 4WD system. This
unique system is interactive with the road,
continually monitoring and adjusting torque
delivery to the front and rear wheels to
optimize vehicle control. 4WD Indicator Lights
The indicator lights illuminate in the
information display in the reconfigurable
telltale (RTT) location under the following
conditions. See Warning Lamps and
Indicators (page 98).
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4X4 mode was selected prior to the fault
condition occurring. It will not default to 4X2
in all circumstances. When this warning is
displayed, have your vehicle serviced by an
authorized dealer.
4X2 Momentarily illuminates when 4X2
is selected.
4X4 AUTO Continuously illuminates when 4X4
AUTO is selected.4X4 Continuously illuminates when 4X4
is selected.
CHECK 4X4 Displays when a 4X4 fault is
present.
4WD Switch Positions WARNING
Utility and four-wheel drive vehicles
are not 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 or abrupt
maneuvers in these vehicles. 174

Note:
The AdvanceTrac® with RSC® stability
enhancement system can be turned off
manually by pressing the AdvanceTrac
button. See Using Traction Control (page
185). This will disable the engine
management feature, allowing the vehicle
to maintain full power and enhanced
momentum through the obstacle.
Note: The Control Trac® selector switch
should not be changed while the rear wheels
are slipping. The Control Trac® system functions in three
modes:
•
4X2
delivers power to the rear wheels
only. The information display will
momentarily display 4x2 when this mode
is selected. This mode is appropriate for
normal on-road driving on dry pavement
and provides the best fuel economy.
• 4X4 AUTO
provides electronic control
four-wheel drive with power delivered to
all four wheels, as required, for increased
traction. The information display will
display 4A when this mode is selected.
This mode is appropriate for all on-road
driving conditions, such as dry road
surfaces, wet pavement, snow, or gravel.
• 4X4
provides electronically locked
four-wheel drive power to front and rear
wheels. The information display will
display 4X4 when this mode is selected.
This mode is not recommended for use
on dry pavement. This mode is only
intended for severe winter or off-road
conditions, such as deep snow, ice or
shallow sand. Shifting between system modes
Note:
Momentarily releasing the accelerator
pedal while a shift in progress message
displays will improve
engagement/disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Press any button (4X2, 4X4 AUTO or 4X4) at
a stop or while driving. The information
display may display a message indicating a
4X4 shift is in progress. Once the shift is
complete the information display will then
display the system mode selected.

in loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering, acceleration
and braking. This could result in an increased
risk of vehicle roll over, loss of vehicle control
and personal injury. Use all available road
surface to bring your vehicle to a safe
direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of surface
to another (i.e. from concrete to gravel) there
will be a change in the way your vehicle
responds to a maneuver (i.e. steering,
acceleration or braking).
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid excessive wheel slip.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck to
the point that assistance may be required
from another vehicle. Remember, you may
be able to back out the way you came if you
proceed with caution.
Mud and Water
Note:
Driving through deep water may
damage the vehicle.
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal while moving slowly. Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even 4WD vehicles can lose traction in
slick mud. As when you are driving over
sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does
slide, steer in the direction of the slide until
you regain control of the vehicle.
If the transmission, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.

“Tread Lightly” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities in
our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly”
.
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on
steep slopes or hills.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down. When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back 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. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your 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 your vehicle slides
while cornering, steer in the direction of the
slide until you regain control of your vehicle. 179

LIMITED SLIP DIFFERENTIAL
This axle provides added traction on slippery
surfaces, particularly when one wheel is on
a poor traction surface. Under normal
conditions, the limited-slip axle functions like
a standard rear axle. The axle may exhibit a
slight noise or vibration during tight turns
with low vehicle speed. This is normal
behavior and indicates the axle is working.

PRINCIPLE OF OPERATION
WARNINGS
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 on a
flat surface at parking speeds. Certain
objects with surfaces that absorb ultrasonic
waves, surrounding vehicle's parking aid
systems, traffic control systems, fluorescent
lamps, 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. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system. WARNINGS
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 your
vehicle. The system may not detect smaller
objects, particularly those close to the
ground. 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 or 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 or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 54).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear
sensing system may detect that add-on
device and therefore provide warnings. It is
suggested that you disable the rear sensing
system when you attach an add-on device
to your vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on. You can turn the system on or off
by pressing the parking aid button.
If your vehicle does not have a
parking aid button, the system can be
switched off through the information display
menu or from the pop-up message that
appears once you shift the transmission into
reverse (R).
See General Information (page
102).
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 108).

REAR PARKING AID
The rear sensors are only active when the
transmission is in reverse (R). As your vehicle
moves closer to the obstacle, the rate of the
audible warning increases. When the
obstacle is less than 12 in (30 cm) away, the
warning sounds continuously. If the system
detects a stationary or receding object
farther than
12 in (30 cm) from the corners of
the bumper, the tone sounds for only three
seconds. Once the system detects an object
approaching, the warning sounds again. Coverage area of up to
6 ft (1.8 m) from the
rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.
The system detects certain objects while the
transmission is in reverse (R) :
• Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a moving
object is approaching the rear of your
vehicle at a speed of
3 mph (5 km/h) or
less.
• Your vehicle is moving at a speed of less
than 3 mph (5 km/h) and a moving object
is approaching the rear of your vehicle
at a speed of less than
3 mph (5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is less than 12 in (30 cm) away from
the bumper. Obstacle Distance Indicator
(If Equipped)
The system provides obstacle distance
indication through the information display.
The distance indicator displays when the
transmission is in reverse (R).
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks illuminate
and move towards the vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks are grayed out.
FRONT PARKING AID
The front parking aid sensors automatically
turn on when you shift into reverse (R) or a
forward gear.
The front sensors are active when the
transmission is in any position other than
park (P) and the vehicle speed is below
7 mph (12 km/h)
.
194
Navigator (TB5) Canada/United States of America, enUSA, First Printing Parking AidsE130178

Coverage area of up to 28 in (70 cm) from
the front bumper. There is decreased
coverage area at the outer corners.
The system sounds an audible warning when
obstacles are near either bumper in the
following manner:
• Objects detected by the front sensors
are indicated by a high-pitched tone from
the front of the vehicle.
• Objects detected by the rear sensors are
indicated by a lower pitched tone from
the rear of the vehicle. •
The sensing system reports the obstacle
which is closest to the front or rear of the
vehicle. For example, if an obstacle is
12 in (30 cm) from the front of the vehicle
and, at the same time, an obstacle is only
6 in (15 cm)
from the rear of the vehicle,
the lower pitched tone sounds.
• An alternating warning sounds from the
front and rear if there are objects at both
bumpers that are closer than
12 in
(30 cm).
The system provides warnings when your
vehicle is moving or when your vehicle is
stationary and the detected obstacle is less
than
12 in (30 cm) away from the bumper.
REAR VIEW CAMERA WARNINGS
The rear view camera system is a
reverse aid supplement device that still
requires the driver to use it in conjunction
with the interior and exterior mirrors for
maximum coverage. WARNINGS
Objects that are close to either corner
of the bumper or under the bumper,
might not be seen on the screen due to the
limited coverage of the camera system. Back up as slow as possible since
higher speeds might limit your reaction
time to stop your vehicle. Use caution when using the rear video
camera and the luggage compartment
door is ajar. If the luggage compartment door
is ajar, the camera will be out of position and
the video image may be incorrect. All
guidelines disappear when the luggage
compartment door is ajar. Use caution when turning camera
features on or off. Make sure your
vehicle is not moving. The rear view camera system provides a
video image of the area behind your vehicle.
During operation, lines appear in the display
which represent your vehicle
’s path and
proximity to objects behind your vehicle.
