GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 264).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 85).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control
light illuminates steadily if the
system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status.
You can switch the system off by either
using the information display controls or
the switch. Using the Information Display
Controls
You can switch this feature off or on in the
information display. See General
Information (page 89).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off
or on.
The switch illuminates when traction
control is off.
System Indicator Lights and
Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

PRINCIPLE OF OPERATION
WARNINGS
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. 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 fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
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 system applies
higher brake force.
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.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 166).

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
The system may not detect objects
with surfaces that absorb reflection.
Always drive with due care and
attention. Failure to take care may result
in a crash. Traffic control systems, inclement
weather, air brakes, external motors
and fans may affect the correct
operation of the sensing system.This may
cause reduced performance or false alerts. The system may not detect small or
moving objects, particularly those
close to the ground.
Note:
If your vehicle is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present. See
Principle of Operation (page 51).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 89).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 98).
REAR PARKING AID
(If Equipped)
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.

DRIVER ALERT (If Equipped)
PRINCIPLE OF OPERATION WARNINGS
The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are
still responsible to drive with due care and
attention. 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. The system may not function if the
sensor is blocked.
Take regular rest breaks if you feel
tired. Do not wait for the system to
warn you.
Certain driving styles may result in
the system warning you even if you
are not feeling tired.
In cold and severe weather
conditions the system may not
function. Rain, snow and spray can
all 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 may not operate correctly
if you modify the ride height.
Note: Keep the windshield free from
obstructions. For example, bird droppings,
insects, snow or ice. Note:
If the camera is blocked or if the
windshield is damaged, the system may not
function.
Note: If enabled in the menu, the system
activates at speeds above
40 mph
(64 km/h). When below the activation
speed, the information display informs the
driver that the system is unavailable. 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 alerts you using a
chime and a message in the information
display.
USING DRIVER ALERT
Switching the System On and Off
Switch the system on or off using the
information display.
See General
Information (page 89).
When active, the system monitors your
alertness level based upon your driving
behavior in relation to the lane markings
and other factors.
System Warnings
Note: The system does not issue warnings
below approximately
40 mph (64 km/h).
186
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Driving AidsE249505

The warning system has two stages. First,
the system issues a temporary warning
that you need to take a rest. This message
only appears for a short time. If 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.
System Display
When active, the system runs
automatically in the background and only
issues a warning if required. You can view
the status at any time using the
information display. See General
Information (page 89).
The alertness level is shown by six steps
in a colored bar. The current assessment of your alertness
is within a typical range.
The current assessment of your alertness
indicates that you should rest as soon as
safely possible.
The status bar travels from left to right as
the calculated alertness level decreases.
As the meter approaches the rest icon, the
color turns from green to yellow to red. The yellow position indicates the first
warning is active and the red position
indicates the second warning is active.
Note:
If you have recently received a
warning, you should consider resting, even
if the current assessment is within the
typical range.
Note: If the camera sensor cannot track the
road lane markings, or if your vehicle speed
drops below approximately
40 mph
(64 km/h), the alertness level changes to
grey for a short time and the information
display informs you that the system is
unavailable.
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.

System Sensor Blockage
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 system alert
indicators will remain ON and the system
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:
When towing a trailer, the sensors
may detect the trailer thus causing a false
alert. It may be desirable to turn the Blind
Spot Information System off if the false
alerts become annoying.
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 98).
System Limitations
The system does have its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
may limit vehicle detection.
The following are other situations that may
limit the system:
• Certain maneuvering of vehicles
entering and exiting the blind zone.
• Vehicles passing through the blind zone
at very fast rates.
• When several vehicles forming a
convoy pass through the blind zone.
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information (page
89). 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 system switches back on every
time you start your vehicle.
