WARNING: If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. See your authorized
dealer. 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 the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or 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.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability
Control ™, it may be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
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 will
result in less vehicle control, not more.
Additionally, smooth variations of the
accelerator and/or brake pedal
pressure should be utilized if changes
in vehicle speed are called for. Avoid abrupt steering, acceleration or braking
which could result in an increased risk
of loss of vehicle control, vehicle
rollover and/or personal injury. Use all
available road surface to return the
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 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.
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 spinning the wheels.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to 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 your vehicle.
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the hubs (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.
193
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-Printing Four-Wheel Drive
(If Equipped)

Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal.
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.
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. A danger lies in losing
traction, slipping sideways and possibly
rolling 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 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. The front wheels have to be
turning in order to steer the vehicle.
Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not
“pump”
the brakes.

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 information
display controls or 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
the 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
When you switch the system off or on, a
message appears in the information
display showing system status.
You can switch the system off by either
using the information display controls or
the switch. Using the Information Display
Controls
You can switch this feature off or on in the
information display. See General
Information (page 105).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off
or on.
System Indicator Lights and
Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in 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.

PRINCIPLE OF OPERATION
WARNING: 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. 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
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.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one
or more of the 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 199). Vehicle without stability control

USING TERRAIN CONTROL
The terrain management system optimizes
drivability and comfort as well as
maximizing traction while operating on
different types of terrain.
Turn the control located on the center
console to choose between the following
modes:
Grass/Gravel/Snow mode
should be selected where a firm
surface is covered with loose or
slippery material such as packed
snow, ice, water, grass, or a thin
layer of gravel or sand. For deep
1
gravel or sand, select Sand
mode. If the vehicle cannot gain
traction in deep snow, switching
off the traction control system
may help (switch traction
control back on when you regain
traction). See
Using Traction
Control (page 199).
Sand
mode should be selected
in soft dry sand or deep gravel. If
crossing wet sand that may be
sufficiently deep enough for the
wheels to sink into the surface,
select Mud/Ruts mode.
2 Mud/Ruts
mode should be
selected for muddy, rutted, soft
or uneven terrain.
3
Normal
mode is for on-road
conditions and should be
selected before driving on
surfaces which are similar to a
hard road surface or once the
need for a special mode has
passed. Select Normal mode
when towing a trailer.
4
Note: The Sand and Mud/Ruts modes are
for off-road use only.
Note: The curve control portion of the
AdvanceTrac® system is unavailable when
you select Sand or Mud/Ruts.
If the system becomes inoperable,
selecting some modes may not be possible
and a message displays. If it becomes
inoperable due to a system malfunction,
all of the mode indicators on the control
turn off and one of the following messages
appears in the information display:
TERRAIN MANAGEMENT SYSTEM
FAULT:
Turning the engine on and off may
clear the fault. If that does not work, have
the system serviced by an authorized
dealer.
MODE CHANGE NOT ACCEPTED,
RETRY:
A mode change cannot be made
at the time of driver request. Try the mode
change again.
