DRIVER ALERT (If Equipped)
PRINCIPLE OF OPERATION WARNING
The driver alert system is designed
to aid you. It is not intended to
replace your attention and judgment.
You are still responsible to drive with due
care and attention. Note:
The system will store the on or off
setting in the information display menu
through ignition cycles.
Note: If enabled in the menu, the system
will be active at speeds above
40 mph
(64 km/h). When below the activation
speed, the information display will inform
the driver that the system is unavailable.
Note: The system works as long as one lane
marking can be detected by the camera.
Note: If the camera is blocked or if the
windshield is damaged, the system may not
function.
Note: The system may not be available in
poor weather or other low visibility
conditions.
The system automatically monitors your
driving behavior using various inputs
including the front camera sensor.
If the system detects that your driving
alertness is reduced below a certain
threshold, the system will alert you using
a chime and a message in the cluster
display.
USING DRIVER ALERT
Switching the System On and Off
Switch the system on or off using the
information display. See
General
Information (page 99). When activated, the system will monitor
your alertness level based upon your
driving behavior in relation to the lane
markings, and other factors.
System Warnings
Note:
The system will not issue warnings
below approximately
40 mph (64 km/h).
The warning system has two stages. At
first, the system issues a temporary
warning that you need to take a rest. This
message will only appear for a short time.
If the system detects further reduction in
driving alertness, it may issue another
warning that will remain 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
(If
Equipped) WARNINGS
Always drive with due care and
attention when using and operating
the controls and features on your
vehicle. At all times, you are responsible for
controlling your vehicle, supervising
the system and intervening, if
required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. In cold and severe weather
conditions the system may not
function. Rain, snow and spray can
all limit sensor performance.

WARNINGS
Large contrasts in outside lighting
can limit sensor performance.
The system will not operate if the
sensor cannot track the road lane
markings.
If damage occurs in the immediate
area surrounding the sensor, have
your vehicle checked as soon as
possible. Note:
The system works above 40 mph
(64 km/h).
Note: The system works as long as the
camera can detect one lane marking.
Note: The system may not function if the
camera is blocked or there is damage to the
windshield.
Note: When Aid mode is on and the system
detects no steering activity for a short
period, the system will alert you to put your
hands on the steering wheel. The system
may detect a light grip or touch on the
steering wheel as hands off driving.
The system notifies you to stay in your lane
through the steering system and the
instrument cluster display when the front
camera detects an unintentional drift out
of your lane is likely to occur. The system
automatically detects and tracks the road
lane markings using a camera mounted
behind the interior rear view mirror.
Switching the System On and Off
Note: The system 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 is set to Alert.
Note: If a MyKey is detected, pressing the
button will not affect the on or off status of
the system. Press the button on the steering
wheel stalk to switch the system
on or off.
System Settings

Note:
The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It’ s only designed to alert
you to vehicles in the blind spot zones.
Note: When a vehicle passes quickly
through the blind spot zone, typically fewer
than two seconds, the system does not
trigger.
Using the System
The Blind Spot Information System turns
on when you start the engine and you drive
your vehicle forward above 5 mph
(8 km/h).
For automatic transmissions, the Blind
Spot Information System remains on while
the transmission is in drive (D). If shifted
into reverse (R) or park (P) the Blind Spot
Information System turns off. Once shifted
back into drive (D), the Blind Spot
Information System turns back on when
you drive your vehicle above
5 mph
(8 km/h).
For manual transmissions, the Blind Spot
Information System is on for all gears
except the reverse (R).
Note: The Blind Spot Information System
does not function in reverse (R) or park (P).
System Lights and Messages The Blind Spot Information System
illuminates an amber alert indicator in the
outside mirror on the side of your vehicle
the approaching vehicle is coming from.
When the Blind Spot Information System
is alerting on a vehicle and the
corresponding turn signal is ON, the Blind
Spot Information System alert indicator
flashes as an increased warning level.
The alert indicator dims when the system
detects nighttime darkness.
Note:
The alert indicator flashes in case of
an alert and the turn signal is set to that side
at the same time.
System Sensor Blockage WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. 221
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving AidsE142442

The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Any dirt, mud and
snow in front of the sensors and/or driving
in heavy rain can cause system
degradation. Also, other types of
obstructions in front of the sensor can
cause system degradation. This is referred
to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance. If the system detects a degraded
performance condition, a message warning
of a blocked sensor will appear in the
information display. Also the BLIS alert
indicators will remain ON and BLIS will no
longer provide any vehicle warnings. You
can clear the information display warning
but the alert indicators will remain
illuminated.
A "blocked" condition can be cleared in
two ways:
•
After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System with a trailer attached
will cause poor system performance.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See Information
Messages (page 113).
222
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving AidsE205199

Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See General Information (page
99). When the Blind Spot Information
System switches off, you will not receive
alerts and the information display shows
a system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer. CROSS TRAFFIC ALERT
(If
Equipped) WARNING
To help avoid personal injury, NEVER
use the Cross Traffic Alert system as
a replacement for using the interior
and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross Traffic Alert is not a
replacement for careful driving. Cross Traffic Alert is designed to warn you
of vehicles approaching from the sides
when the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you start
the engine and you shift into reverse (R).
Once shifted out of reverse (R), Cross
Traffic Alert turns off.
Note:
Cross Traffic Alert only functions
while your transmission is in reverse (R).
Cross Traffic Alert is designed to detect
vehicles that approach with a speed up to
37 mph (60 km/h)
. Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Reversing slowly helps
increase the coverage area and
effectiveness.
223
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving Aids

In this first example, the left sensor is only
partially obstructed; zone coverage to the
right is nearly maximized.
224
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving AidsE142440 E142441

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.
System Lights, Messages and
Audible Alerts
The Cross Traffic Alert illuminates an
amber alert indicator in the outside mirror
on the side of your vehicle the approaching
vehicle is coming from. Cross Traffic Alert
also sounds an audible alert and a
message appears in the information
display indicating a vehicle is coming from
the right or left. Cross Traffic Alert works
with the reverse sensing system that
sounds its own series of tones. See Rear
Parking Aid (page 195). The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Do not allow mud,
snow or bumper stickers to obstruct these
areas, this can cause degraded system
performance. See Blind Spot
Information System (page 220). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A
corresponding message appears in the
information display as soon as you shift
the transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
225
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving AidsE142442 E205199

The following are other situations that may
limit the Cross Traffic Alert performance:
•
Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 37 mph
(60 km/h).
• Driving in reverse faster than
7 mph
(12 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Cross Traffic Alert
off. If your vehicle has a tow bar but no
factory equipped trailer tow module, it is
recommended to turn the Cross Traffic Alert
off manually. Operating Cross Traffic Alert
with a trailer attached will cause poor Cross
Traffic Alert performance.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message will
appear in the information display. See
Information Messages
(page 113).
Switching the System Off and On
You can temporarily switch Cross Traffic
Alert off in the information display. See
General Information
(page 99). When
you switch Cross Traffic Alert off, you will
not receive alerts and the information
display will display a system off message. Note:
The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.
STEERING
Electric Power Steering WARNINGS
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 by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, 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.
226
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving Aids

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
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 (If
Equipped) WARNINGS
This system is an extra driving aid. It
does not replace your attention and
judgment, or the need to apply the
brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle. The Pre-Collision Assist system with
brake support cannot help prevent
all collisions. Do not rely on this
system to replace your judgment and the
need to maintain correct distance and
speed. Note:
The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of your vehicle.
Note: The Pre-Collision Assist system is
active at speeds above approximately
5 mph (8 km/h)
. The system alerts you of certain collision
risks. The system's sensor detects your
vehicle's rapid approach to other vehicles
traveling in the same direction as your
vehicle.
227
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Driving AidsE156130 E156131

When your vehicle rapidly approaches
another vehicle, a red warning light flashes
and a tone sounds.
The brake support system assists you in
reducing any collision speed by
pre-charging the brakes. If the risk of
collision continues to increases after the
audio-visual warning, the brake support
prepares the brake system for rapid
braking. The system does not
automatically activate the brakes, but if
the brake pedal is pressed even lightly, the
brakes apply full stopping power.
Using the Pre-Collision Assist
System
WARNING
The Pre-Collision Assist system
’s
brake support reduces collision
speed only if you brake your vehicle
before any collision. As in any typical
braking situation, you must press your
brake pedal. You can adjust the warning system's
sensitivity through your information
display. See General Information (page
99). Note:
When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See
General Information (page
99).
Blocked Sensors If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the pre-collision assist
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.
