Driving in Special Conditions With
Four-Wheel drive (4WD)
Note:
Use of the 4WD system in slippery,
deep snow, and sand drive modes on dry
surfaces could produce some vibration,
driveline bind up, or excessive tire wear as
these drive modes are intended for slippery
and loose surfaces.
Note: The design of 4WD vehicles are for
driving on sand, snow, mud and rough roads
and have operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway.
Basic Operating Principles in Special
Conditions
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice. If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It could be safer to stay on the apron
or shoulder of the road and slow down
gradually before returning to the
pavement. You could lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often could be less risky to strike
small objects, such as highway
reflectors, with minor damage to your
vehicle rather than attempt a sudden
return to the pavement which could
cause the vehicle to slide sideways out
of control or rollover. Remember, your
safety and the safety of others should
be your primary concern.
If Your Vehicle Gets Stuck WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.

(If Equipped)

If your vehicle gets stuck in mud or snow
you can rock it 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 comes with AdvanceTrac®
with Roll Stability Control
™, it could be
beneficial to disengage the AdvanceTrac®
with Roll Stability Control ™ system while
attempting to rock the vehicle.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the
transmission and tires could occur or the
engine could overheat.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid
"over-driving" your vehicle (for
example, turn the steering wheel only
as rapidly and as far as required to
avoid the emergency). Excessive
steering can 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 is 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 could be required
from another vehicle. Remember, you
could be able to back out the way you
came if you proceed with caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability could
be limited.
Note: Driving through deep water could
damage your vehicle.
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 could stall.
210
Explorer (CTW), enUSA, Edition date: 202007, Second-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
Although natural obstacles could 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. 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.
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 can 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.

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.

Possible Cause
Symptom
The vehicle speed is greater than 22 mph (35 km/h)
for parallel parking or greater than 19 mph (30 km/h)
for perpendicular parking.
You recently disconnected or replaced the battery. After
you reconnect the battery you must drive your vehicle
on a straight road for a short period of time.
An irregular curb along the parking space prevents the
system from correctly aligning your vehicle.
The system does not correctly
position your vehicle in a
parking space.
Vehicles or objects bordering the space may not be
correctly parked.
Your vehicle stopped too far past the parking space.
The tires may not be correctly installed or maintained.
For example, not inflated correctly, improper size, or of
different sizes.
A repair or alteration changes the detection capabilities.
A parked vehicle has a high attachment. For example,
a salt sprayer, snowplow or moving truck bed.
The parking space length or position of parked objects
changes after your vehicle passes the space.
You are using a spare tire or a tire more significantly
worn than the other tires.
The temperature around your vehicle quickly changes.
For example, driving from a heated garage into cold
outside temperature, or after leaving a car wash.
REAR VIEW CAMERA WARNING:
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. WARNING:
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. WARNING:
Reverse your vehicle
slowly. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death.

Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
Transitioning between no lane markings to lane markings or vice versa.
There is standing water on the road.
Faint lane markings, for example partial yellow lane markings on concrete roads.
Lane width is too narrow or too wide.
The camera has not been calibrated after a windshield replacement.
Driving on tight roads or on uneven roads. Why does the vehicle not come back toward the middle of the lane, as expected, in the
Aid or Aid + Alert mode?
High cross winds are present.
There is a large road crown.
Rough roads, grooves or shoulder drop-offs.
Heavy uneven loading of the vehicle or improper tire inflation pressure.
The tires have been changed, or the suspension has been modified.
BLIND SPOT INFORMATION

be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note:
For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations. WARNING: Exceeding any
vehicle weight rating can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death. Steps for determining the
correct load limit:
1. Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle ’s placard.
2. Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3. Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lb.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1,400 lb. and there will
be five 150 lb. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.

TOWING A TRAILER
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. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Note: See
Recommended
Towing Weights (page 289).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 312).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. 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 ball mount with the
correct rise or drop and load
capacity. 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.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
282).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
