2021 FORD EXPLORER warning

The design of the system is to detect
vehicles that could have entered the blind
spot zone. The detection area is on both
sides of your vehicle, extending rearward
from the exterior mirrors to approximately
13 ft (4 m) beyond the rear bumper. The
detection area extends to approximately
59 ft (18 m)
beyond the rear bumper when
the vehicle speed is greater than 30 mph
(48 km/h) to alert you of faster
approaching vehicles.
Note: The system does not prevent contact
with other vehicles. It does not detect
parked vehicles, pedestrians, animals or
other infrastructures.
Using the Blind Spot Information
System
Vehicles with Automatic Transmission
The system turns on when all of the
following occur:
• You start your vehicle.
• You shift into drive (D).
• The vehicle speed is greater than
6 mph (10 km/h)
.
Note: The system does not operate in park
(P) or reverse (R).
System Lights and Messages When the system detects a vehicle, an
alert indicator illuminates in the exterior
mirror on the side the approaching vehicle
is coming from. If you turn the direction
indicator on for that side of your vehicle,
the alert indicator flashes.
Note:
The system may not alert you if a
vehicle quickly passes through the detection
zone.
Blocked Sensors The sensors are behind the rear bumper
on both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors become blocked, a message
could appear in the information display.
See
Information Messages (page 121).
The alert indicators remain illuminated but
the system does not alert you.
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
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following:

•
Information display. See General
Information (page 114).
• Touchscreen. See Settings (page 464).
When you switch the system off, a warning
lamp illuminates and the alert indicators
flash twice.
Note: The system remembers the last
setting when you start your vehicle.
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer.
Blind Spot Information System
with Trailer Tow
(If Equipped) The design of the system is to aid you in
detecting vehicles that could have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When you attach and have setup a trailer,
the blind spot information system with
trailer tow becomes active when driving
forward above
6 mph (10 km/h). You can switch the system off in the
information display.
See General
Information (page 114). If you switch the
blind spot information system off, blind
spot information system with trailer tow
turns off.
Setting up a Trailer
You can setup a trailer through the
information display.
See General
Information (page 114). Trailer length.
A
Trailer width.
B
Trailer hitch ball.
C
Note: Measure the width of the trailer at
the front of the trailer, not the widest point.
The maximum width that the system can
support is
8.2 ft (2.5 m)(B).
Note: The trailer length is the distance
between the trailer hitch ball and the rear
of the trailer. The maximum length that the
system can support is
33 ft (10 m)(A).
When setting up a trailer, a sequence of
screens appear asking for trailer
information:
• Select trailer screen: None, Trailer A,
Trailer B or Trailer C.
Note: You can select only one trailer on
small information displays.
Select one of the trailers and press OK. The
menu goes to the next screen.
• Width less than
8.2 ft (2.5 m) and
length less than 33 ft (10 m)?
266
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving AidsE293525 E293526

Note:
You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is
8.2 ft (2.5 m) or less.
If no, the system turns off.
If yes, the menu goes to the next screen.
• Enter length of trailer:
Toggling up or down using the menu
buttons increases or decreases the
measurement by
3 ft (1 m). Select a length
that is equal to or within 3 ft (1 m) of the
actual measured length. For example, if
the actual measured length is 25 ft (7.6 m),
toggle the length in the menu to 8 m or 27
ft. When you enter the length of the trailer,
this saves the system setup.
Note: When you connect a trailer, but do
not setup a trailer in the blind spot
information system, the system turns off
and a warning appears in the information
display.
Note: If the trailer is a bike rack or cargo
rack with electrical lighting, enter a length
of
3 ft (1 m). Cross Traffic Alert remains on
for trailers with a length of 3 ft (1 m) or less.
Note: The system requires proper
measurement and measurement entry to
function as designed.
System Operation
If you select a trailer in the information
display prior to connecting a trailer, the
system loads that configuration and the
information display shows a message
when you connect the trailer. A second
message appears stating cross traffic alert
is off, unless a trailer is set up with a length
of
3 ft (1 m). The blind spot information
system with trailer tow still functions
normally when driving forward. If you connect a trailer, a message appears
indicating that you attached a trailer. If you
have not selected a trailer previously,
another message appears requesting you
to select one of the trailers in the list or add
a new trailer. The blind spot information
system with trailer tow does not function
without a trailer selected. If you do not
select a trailer, a message appears in the
information display stating it has
deactivated the system. This message
might not appear until your vehicle speed
reaches
22 mph (35 km/h).
The blind spot information system with
trailer tow activates when driving forward
for that particular trailer set up. If you cycle
the ignition, the blind spot information
system with trailer tow continues to
function using the last trailer you selected.
Trailer Considerations
The system works with a trailer with a front
width of
8.2 ft (2.5 m) or less, and a total
length from the trailer hitch ball to the rear
of the trailer of
33 ft (10 m) or less.
Some trailers could cause a slight change
in system performance:
• Wide box trailers, especially those
wider than the towing vehicle, could
cause false alerts to occur when driving
next to infrastructure or near parked
cars. A false alert could also occur
while making a 90-degree turn or
driving through a roundabout.
• Wide trailers that have a total length
greater than
20 ft (6 m) could cause
delayed alerts when a vehicle is
passing at high speeds.
267
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving Aids

•
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).

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Cross Traffic Alert System Sensors
The sensors are behind the rear bumper
on both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R).

STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation. Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
(If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
PRE-COLLISION ASSIST WARNING: You are responsible for
controlling your vehicle at all times. 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
the loss of control of your vehicle,
personal injury or death.
