the system detects further reduction in
driving alertness, it may issue another
warning that remains in the information
display for a longer time. You can press OK
on the steering wheel control to clear the
warning.
Resetting the System
You can reset the system by either:
• Switching the ignition off and on.
• Stopping the vehicle and then opening
and closing the driver ’s door.
LANE KEEPING SYSTEM 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. WARNING: Always drive with due
care and attention when using and
operating the controls and features on
your vehicle. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
Large contrasts in
outside lighting can limit sensor
performance. WARNING:
The system will not
operate if the sensor cannot track the
road lane markings. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in
a false or missed warning. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from
obstruction. WARNING:
If damage occurs in the
immediate area surrounding the sensor,

When you switch the system on and it
detects an unintentional drift out of your
lane is likely to occur, the system notifies
or assists you to stay in your lane through
the steering system and information
display. In Alert mode, the system provides
a warning by vibrating the steering wheel.
In Aid mode, the system provides steering
assistance by gently counter steering your
vehicle back into the lane.
When the system is functioning in the
combined Alert and Aid mode, the system
first provides steering assistance by gently
counter steering your vehicle back into the
lane, followed by a warning that vibrates
the steering wheel if the vehicle is still out
of the lane markings.
Switching the System On and Off
Note:
The on or off setting is stored until it
is manually changed, unless a MyKey is
detected. If the system detects a MyKey, it
defaults to on and the mode sets to alert. Press the button on the direction indicator
stalk to switch the system on or off.
System Settings
The system has optional setting menus
available. The system stores the last
known selection for each of these settings.

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.
273
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Driving Aids

WARNING: The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead
to a crash or personal injury. WARNING: The system may fail or
operate with reduced function during
cold and severe weather conditions.
Snow, ice, rain, spray and fog can
adversely affect the system. Keep the
front camera and radar free of snow and
ice. Failure to take care may result in the
loss of control of your vehicle, serious
personal injury or death. WARNING:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types,
and pedestrians. Apply the brakes when
necessary. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
The system cannot
help prevent all crashes. Do not rely on
this system to replace driver judgment
and the need to maintain a safe distance
and speed.
Using the Pre-Collision Assist
System
The system is active at speeds above
approximately
3 mph (5 km/h) and
pedestrian detection is active at speeds
up to
50 mph (80 km/h). If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system is designed to provide three levels
of functionality:
1. Alert
2. Brake Support
3. Active Braking
Alert
: When active, a flashing visual
warning appears and an audible warning
tone sounds.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking.
Brake support does not automatically
apply the brakes. If you press the brake
pedal, the system could apply additional
braking up to maximum braking force, even
if you lightly press the brake pedal.
Active Braking
: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.

Evasive Steering Assist (If Equipped)
If your vehicle is rapidly approaching a
stationary vehicle or a vehicle traveling in
the same direction as your vehicle, the
system is designed to help you steer
around the vehicle.
The system only activates when all of the
following occur:
• The Pre-Collision Assist system detects
a vehicle ahead and starts to apply
Active Braking.
• You turn the steering wheel in an
attempt to steer around the vehicle.
After you turn the steering wheel, the
system applies additional steering torque
to help you steer around the vehicle. After
you pass the vehicle, the system applies
steering torque in the opposite direction to
encourage you to steer back into the lane.
The system deactivates after you fully pass
the vehicle.
Note: The system does not automatically
steer around a vehicle. If you do not turn the
steering wheel, the system does not
activate.
Note: The system does not activate if the
distance to the vehicle ahead is too small
and the system cannot avoid a crash.
Adjusting the Pre-Collision Assist
Settings
You can adjust the following settings by
using the touchscreen. See Settings (page
464
).
• You can change Alert and Distance
Alert sensitivity to one of three possible
settings.
• You can switch Distance Indication and
Alert on or off. •
If required, you can switch Active
Braking on or off.
• If required, you can switch Evasive
Steering Assist on or off.
Note: Active Braking and Evasive Steering
Assist automatically turn on every time you
switch the ignition on.
Note: If you switch Active Braking off,
Evasive Steering Assist turns off.
