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.

WARNING: Pay close attention to
changing road conditions such as
entering or leaving a highway, on roads
with intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury. WARNING:
The system is not a
crash warning or avoidance system. WARNING:
Do not use the system
when towing a trailer that has
aftermarket electronic trailer brake
controls. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use tire sizes
other than those recommended because
this can affect the normal operation of
the system. Failure to do so may result
in a loss of vehicle control, which could
result in serious injury. WARNING:
Do not use the system
with a snow plow blade installed. WARNING:
Do not use the system
in poor visibility, for example fog, heavy
rain, spray or snow. When Following a Vehicle WARNING:
When following a
vehicle that is braking, your vehicle does
not always decelerate quickly enough to
avoid a crash without driver intervention.
Apply the brakes when necessary. Failure
to follow this instruction could result in
personal injury or death.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
ADAPTIVE CRUISE CONTROL

•
Box trailers that have a width greater
than 8.2 ft (2.5 m) could cause early
alerts when you pass a vehicle.
• Clam shell or V-Nose box trailers with
a width greater than
8.2 ft (2.5 m)
could cause delayed alerts when a
vehicle traveling the same speed as
your vehicle merges lanes.
System Errors
If the system detects a fault, a warning
lamp illuminates and a message displays.
See
Information Messages (page 121).
Switching the System On and Off
You can switch the blind spot information
system with trailer tow off by not selecting
a trailer the information display.
See
General Information (page 114). In this
case, the system turns off as long as a
trailer is attached to your vehicle. As soon
as you disconnect the trailer, the blind spot
information system becomes active.
When you switch the system off, a warning
lamp illuminates and the alert indicators
flash twice.
Note: The system remembers the last
trailer setting when you start your vehicle.
You cannot switch off the blind spot
information system with trailer tow when
using MyKey, but you can still change the
trailer settings.
See MyKey ™ (page 64).
To permanently switch the system off,
contact an authorized dealer. CROSS TRAFFIC ALERT WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The
cross traffic alert system is not a
replacement for careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash.
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Slowly reversing helps
increase the coverage area and
effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R).

WHAT IS DRIVE MODE
CONTROL
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain
response. This provides a single location
to control multiple systems performance
settings.
Changing the drive mode changes the
functionality of the following systems:
•
Electric power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 273).
• Electronic stability control and traction
control maintain your vehicle control
in adverse conditions or high
performance driving. See
Stability
Control (page 225).
• Electronic throttle control enhances
the powertrain response to your driving
inputs.
• Transmission controls become
optimized with shift schedules tuned
to each mode.
• Four-wheel drive settings are optimized
and tuned to each mode.
• Electric vehicle mode selections may
be limited. See
Hybrid Vehicle
Operation (page 182).
The system tailors your vehicle
configuration for each mode you select.
Note: Not all settings may be available.
Note: The system has diagnostic checks
that continuously monitor the system for
proper operation. If a mode is unavailable
due to a system fault or change in gear
shifter position, the mode defaults to
Normal. SELECTING A DRIVE MODE
Note:
Drive mode changes may not be
available when the ignition is off or when
the engine is not running.
Note: Button icons shown may vary from
your vehicle. Rotate the drive mode dial on the center
console to select or change a drive mode.
To select drive modes for RWD vehicles
use the console mounted control.
DRIVE MODES
Deep Snow/Sand
(If Equipped)
For snow or soft dry sand. When
stuck in deep snow, use this
mode to help get unstuck.
278
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Drive Mode ControlE298238 E297643 E295420

Note:
Using deep snow/sand mode on dry,
hard surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
Eco For efficient driving. This mode
helps deliver maximum fuel
efficiency and helps to increase
driving range.
Normal For everyday driving. This mode
is a perfect balance of
excitement, comfort and
convenience. This is the default mode after
each ignition cycle.
Slippery For less than ideal road
conditions, such as snow or ice
covered roads. Use this mode for
crossing terrain with a firm surface covered
with loose, wet or slippery material.
Slippery mode lowers throttle response
and, if provided with an automatic
transmission, optimizes shifting for slippery
surfaces.
Note: Using slippery mode on dry, hard
surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery surfaces. Sport For sporty driving with improved
performance handling, and
response. This mode increases
throttle response and provides a sportier
steering feel. If equipped with automatic
transmission, the powertrain system
provides improved gear holding, helping
your vehicle accelerate faster.
Tow/Haul For improved transmission
operation when towing a trailer
or a heavy load. This mode
moves upshifts to higher engine speeds to
reduce the frequency of transmission
shifting. This mode also provide engine
braking in all forward gears, which slows
your vehicle and assists you in controlling
your vehicle when descending a grade. The
amount of downshift braking provided
varies based on the amount you press the
brake pedal.
Trail For muddy, rutted, soft or uneven
terrain.

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.

TRAILER SWAY CONTROL (IF
EQUIPPED) WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages
(page 121). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
282).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Be sure to take into
consideration trailer frontal area.
Do not exceed 20 ft² (1.86 m²) if
your vehicle can tow a class I
trailer, or 55 ft² (5.11 m²) if your
vehicle can tow a class III trailer
weighing more than
5,000 lb
(2,267 kg).
Note: Your vehicle could have
reduced performance when
operating at high altitudes, and
when heavily loaded or towing a
trailer. When driving at elevation,
in order to match driving
performance as perceived at sea
level, reduce gross vehicle weight
and gross combination weight by
2% per
1,000 ft (300 m) of
elevation.

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.
