PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL
(If
Equipped) WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed could increase above
the set speed. The system does not
apply the brakes. Note:
Cruise control disengages if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed when driving
uphill. The cruise controls are on the steering
wheel.

USING ADAPTIVE CRUISE
CONTROL (If Equipped)
WARNINGS
Always pay close attention to
changing road conditions when using
adaptive cruise control. The system
does not replace attentive driving. Failing
to pay attention to the road may result in
a crash, serious injury or death. Do not use the adaptive cruise
control when entering or leaving a
highway, on roads with intersections
or roundabouts or non-vehicular traffic or
roads that are winding, slippery, unpaved,
or steep slopes. Do not use the system in poor
visibility, for example fog, heavy rain,
spray or snow.
Do not use the system when towing
a trailer with aftermarket trailer
brake controls. Aftermarket trailer
brakes will not function properly when you
switch the system on because the brakes
are electronically controlled. Failing to do
so may result in loss of vehicle control,
which could result in serious injury. 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. Adaptive cruise control may not
detect stationary or slow moving
vehicles below
6 mph (10 km/h).
Adaptive cruise control does not
detect pedestrians or objects in the
road.
Adaptive cruise control does not
detect oncoming vehicles in the
same lane. WARNINGS
Adaptive cruise control is not a crash
warning or avoidance system.
Note:
It is your responsibility to stay alert,
drive safely and be in control of the vehicle
at all times.
The system adjusts your vehicle speed to
maintain the set gap between you and the
vehicle in front of you in the same lane.
You can select four gap settings.
The system uses a radar sensor that
projects a beam directly in front of your
vehicle. The adaptive cruise controls are on the
steering wheel.
Switching Adaptive Cruise Control
On
Press
ON.
The indicator, current gap setting
and set speed appear in the
information display.

Setting the Adaptive Cruise Speed
Note:
When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display.
1. Drive to desired speed.
2. Press SET+ or SET-.
3. A green indicator light, the current gap
setting and your set speed appear in
the information display.
4. Take your foot off the accelerator pedal. 5. A vehicle image illuminates if the
system detects a vehicle in front of you. Following a Vehicle WARNINGS
When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does
your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death. Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be
no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death. Note:
When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.
Note: The brakes may emit noise when
applied by the system.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. A
vehicle graphic illuminates in the
instrument cluster.
Your vehicle maintains a consistent gap
from the vehicle ahead until:
• The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of the lane you are in.
• Your vehicle speed falls below
12 mph
(20 km/h).
• You set a new gap distance.
181
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Cruise ControlE164805 E164805

The system applies the brakes to slow your
vehicle to maintain a safe gap distance
from the vehicle in front. The system only
applies limited braking. You can override
the system by applying the brakes.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds when the system
continues to brake. A red warning bar
displays on the windshield and you must
take immediate action.
Setting the Gap Distance
Note:
The gap setting is time dependent
and therefore the distance adjusts with your
vehicle speed.
Note: It is your responsibility to select a gap
appropriate to the driving conditions.
You can decrease or increase the distance
between your vehicle and the vehicle in
front by pressing the gap control. The selected gap appears in the
information display as shown by the bars
in the image.

Overriding the Set Speed WARNING
If you override the system by pressing
the accelerator pedal, it does not
automatically apply the brakes to
maintain a gap from any vehicle ahead. When you press the accelerator pedal, you
override the set speed and gap distance.
When you override the system,
the green indicator light
illuminates and the vehicle
image does not appear in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.

the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed
Press
CNCL or tap the brake pedal. The
set speed does not erase.
Resuming the Set Speed
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Press
RES. Your vehicle speed returns to
the previously set speed and gap setting.
The set speed displays continuously in the
information display when the system is
active.
Automatic Cancellation
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
The system does not operate below
12 mph (20 km/h)
.
Automatic cancellation can also occur if:
• The tires lose traction.
• The engine speed is too low.
• You apply the parking brake. Hilly Condition Usage
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.
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.
Switching Adaptive Cruise Control
Off
Note: You erase the set speed and gap
setting when you switch the system off.
Press
OFF when the system is in standby
mode, or switch the ignition off.
Detection Issues WARNINGS
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. If the system malfunctions, have your
vehicle checked as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.
183
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Cruise Control

Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.
System Not Available
The system may not turn on if there is:
•
A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system.
Blocked Sensor Note:
You cannot see the sensor. It is
behind a fascia panel.
A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.

Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Cruise ControlE71621 E145632

Possible Causes and Actions for This Message Displaying:
Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar is dirty or
obstructed.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. This happens, for example, when driving in sparse rural or desert
environments. A false blocked condition either self clears, or clears after you restart your
vehicle.
Switching to Normal Cruise
Control WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have selected and apply
the brakes when necessary. You can change from adaptive cruise
control to normal cruise control through
the information display. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, and the system
does not respond to lead vehicles.
Automatic braking remains active to
maintain set speed.

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.
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.
COLLISION WARNING SYSTEM
(If Equipped)
PRINCIPLE OF OPERATION WARNINGS
This system is designed to be a
supplementary driving aid. It is not
intended to replace the driver
’s
attention, and judgment, or the need to
apply the brakes. This system does NOT
activate the brakes automatically. Failure
to press the brake pedal to activate the
brakes may result in a collision.
197
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Driving Aids

WARNINGS
The collision warning system with
brake support cannot help prevent
all collisions. Do not rely on this
system to replace driver judgment and the
need to maintain distance and speed. Note:
The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of the vehicle.
Note: The collision warning system is active
at speeds above approximately 5 mph
(8 km/h). This system is designed to alert the driver
of certain collision risks. A radar detects if
your vehicle is rapidly approaching another
vehicle traveling in the same direction as
yours.
If it is, a red warning light illuminates and
an audible warning chime sounds. The brake support system assists the driver
in reducing the collision speed by charging
the brakes. If the risk of collision further
increases after the warning light
illuminates, the brake support prepares
the brake system for rapid braking. This
may be apparent to the driver. The system
does not automatically activate the brakes
but, if the brake pedal is pressed, full force
braking is applied even if the brake pedal
is lightly pressed.
Using the Collision Warning System WARNING
The collision warning system
’s brake
support can only help reduce the
speed at which a collision occurs if
the driver applies the vehicle ’s brakes. The
brake pedal must be pressed just like any
typical braking situation. The warning system sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See
General Information (page 89).
Note: If collision warnings are perceived as
being too frequent or disturbing then the
warning sensitivity can be reduced, though
the manufacturer recommends using the
highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings. See
General
Information (page 89).
Blocked Sensors 198
Taurus (CPH) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Driving AidsE156130 E156131 E145632

If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed. Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion
The surface of the radar in the grille is dirty
or obstructed in some way
Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed
The surface of the radar in the grille is clean
but the message remains in the display
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Heavy rain, spray, snow, or fog is interfering
with the radar signals
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Swirling water, or snow or ice on the surface
of the road may interfere with the radar signals
System Limitations WARNING
The collision warning system
’s brake
support can only help reduce the
speed at which a collision occurs if
the driver applies the vehicle ’s brakes. The
brake pedal must be pressed just like any
typical braking situation. Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision warning.
These include:
•
Stationary vehicles or vehicles moving
below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane. •
Severe weather conditions (see
blocked sensor section).
• Debris build-up on the grille near the
headlamps (see blocked sensor
section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements
are large (very active driving style).
If the front end of the vehicle is hit or
damaged, the radar sensing zone may be
altered causing missed or false collision
warnings. See your authorized dealer to
have your collision warning radar checked
for proper coverage and operation.
