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 4H or 4L mode on dry,
hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may
damage drive components. 4H and 4L mode
is only intended for consistently slippery or
loose surfaces.
Note: If 4L mode is selected while your
vehicle is moving above 3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L for
proper operation.
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 88).
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4WD 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
2H is selected.
4X4 AUTO Continuously illuminates when
4A is selected. 4X4 HIGH Continuously illuminates when
4H is selected.
4X4 LOW Continuously illuminates when
4L is selected.
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. Note:
If your vehicle is equipped with
AdvanceTrac® with RSC®, the system will
automatically turn off the stability
enhancement feature when you shift the
4WD system into 4L (4X4 LOW). You can
manually turn the system off by pressing
the AdvanceTrac button. See Using
Traction Control (page 175). This will
disable the engine management feature,
allowing the vehicle to maintain full power
and enhanced momentum through the
obstacle. The brake traction enhancement
feature will still be enabled.
Note: The Control Trac® selector switch
should not be changed while the rear wheels
are slipping.

The Control Trac® system functions in four
modes:
•
2H delivers power to the rear wheels
only. The information display will
momentarily display 2H when this
mode is selected. This mode is
appropriate for normal on-road driving
on dry pavement and provides the best
fuel economy.
• 4A
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. •
4H
provides electronically locked
four-wheel drive power to front and
rear wheels. The information display
will display 4H 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.
• 4L
provides electronically locked
four-wheel drive when extra power at
reduced speeds is required. The
information display will display 4L
when this mode is selected. This mode
is not recommended for use on dry
pavement. Use this mode for off-road
low-speed operation or when extra
power is required, such as climbing
steep grades, going through deep sand
or pulling a boat out of the water.
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.
You can move the control from 2H, 4A or
4H 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.
Shifting to or from 4L
Note: 4L mode is not intended for use on
dry pavement.
1. Bring the vehicle to a rolling speed of 3 mph (5 km/h)
or less.
2. Place the gearshift in neutral (N).

The transfer case supples power to all four
wheels. On four-wheel drive vehicles, the
transfer case allows you to select different
4WD modes when necessary. You can find
information on transfer case operation and
shifting procedures in this chapter. You can
find information on transfer case
maintenance in the Maintenance chapter.
You should become thoroughly familiar
with this information before you operate
your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power your
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.
Basic Operating Principles
•
Do not use 4H or 4L on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and
may damage drive components. 4H or
4L modes are only intended for
consistently slippery or loose surfaces.
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed decreases, ease
your vehicle back onto the road. Do not
turn the steering wheel sharply while
returning your vehicle to the road.
It may be safer to stay on the shoulder of
the road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly. It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control or roll over. Remember, your
safety and the safety of others should be
your primary concern.
If your vehicle gets stuck
WARNING
Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle (i.e. turn the steering wheel only as
rapidly and as far as required to avoid the
emergency). Excessive steering can result
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.
167
Expedition (TB7) Canada/United States of America, enUSA, First Printing Four-Wheel Drive (If Equipped)

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.
168
Expedition (TB7) Canada/United States of America, enUSA, First Printing Four-Wheel Drive (If Equipped)E143950

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. Four-wheel drive vehicles have advantages
over two-wheel drive 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.
169
Expedition (TB7) Canada/United States of America, enUSA, First Printing Four-Wheel Drive (If Equipped)E143949

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control
light illuminates steadily if the
system detects a failure. Make sure
you did not manually disable the traction
control system using the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
traction control disabled could lead to an
increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active. Switching the System Off The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See Principle of
Operation (page 46).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes
when a driving condition activates either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on:
• When you switch the traction control
system off.
• If a problem occurs in either of the
systems.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control 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 electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. 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
electronic stability control 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 electronic
stability control system activates, SLOW
DOWN. The system automatically turns on each
time you switch the ignition on. If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
•
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the systems
applies higher brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 175).
