2015 LINCOLN MKZ HYBRID brake sensor

The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your foot
from the brake to the accelerator pedal. The
brakes are released automatically once the
engine has developed sufficient drive to
prevent your vehicle from rolling down the
slope. This is an advantage when pulling
away on a slope, (for example from a car park
ramp, traffic lights or when reversing uphill
into a parking space).
The system will activate automatically on any
slope that will cause significant vehicle
rollback.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep the
brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically. 3. When you remove your foot from the
brake pedal, your vehicle will remain on
the slope without rolling away for about
two or three seconds. This hold time will
automatically be extended if you are in
the process of driving off.
4. Drive off in the normal manner. The brakes will release automatically.

PARKING AID (If Equipped)
WARNINGS
To help avoid personal injury, please
read and understand the limitations of
the system as contained in this section.
Sensing is only an aid for some (generally
large and fixed) objects when moving in
reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather,
air brakes, and external motors and fans may
also affect the function of the sensing
system; this may include reduced
performance or a false activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system. This system is not designed to prevent
contact with small or moving objects.
The system is designed to provide a warning
to assist the driver in detecting large
stationary objects to avoid damaging the
vehicle. The system may not detect smaller
objects, particularly those close to the
ground. WARNINGS
Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the normal
detection zone of the system, may create
false beeps. 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 alarms.
Note: If your vehicle is equipped with
MyKey®, it is possible to prevent turning the
sensing system off. See MyKey™ (page 59).
The sensing system warns the driver of
obstacles within a certain range of the
bumper area. The system turns on
automatically whenever the ignition is
switched on. When receiving a detection warning, the
radio volume is reduced to a predetermined
level. After the warning goes away, the radio
volume returns to the previous level.
The system can be switched off through the
information display menu or from the pop-up
message that appears once the transmission
is shifted into reverse (R) or a front obstacle
is detected. See General Information (page
109
).
If a fault is present in the system, a warning
message appears in the information display
and does not allow the driver to switch the
faulted system on.
See Information
Messages (page 120).

Coverage area of up to 27 inches
(70 centimeters) from the front of
the vehicle and about 6–14 inches
(15–35 centimeters) to the side of
the front end of the vehicle. Refer
to the reverse sensing section for
details on coverage area.
A The system sounds an audible warning when
obstacles are near either bumper in the
following manner:
•
Objects detected by the front sensors
are indicated by a high-pitched tone from
the front radio speakers.
• Objects detected by the rear sensors are
indicated by a lower pitched tone from
the rear radio speakers.
• The sensing system reports the obstacle
which is closest to the front or rear of the
vehicle. For example, if an obstacle is 24
inches (60 centimeters) from the front of
the vehicle and, at the same time, an
obstacle is only 16 inches (40
centimeters) from the rear of the vehicle,
the lower pitched tone sounds.
• If there are objects located at the same
distance in the front and rear of the
vehicle, the system sounds the rear
warning.
For specific information on the reverse
sensing portion of the system, refer to that
section. ACTIVE PARK ASSIST (If Equipped) WARNING
This system is designed to be a
supplementary park aid. It may not
work in all conditions and is not intended to
replace the driver’ s attention and judgment.
The driver is responsible for avoiding
hazards and maintaining a safe distance and
speed, even when the system is in use. Note:
The driver is always responsible for
controlling the vehicle, supervising the
system and intervening if required.
Note: The sensors may not detect objects
in heavy rain or other conditions that cause
disruptive reflections.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
The system detects an available parallel
parking space and automatically steers the
vehicle into the space (hands-free) while you
control the accelerator, gearshift and brakes.
The system visually and audibly instructs you
to park the vehicle.

The controls for using your cruise control are
located on the steering wheel.
Switching the System On
Press and release ON.
The information display will show
the grey indicator light. The current gap setting and
SET will also
display.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and release
SET+. The vehicle
speed will be stored in the memory.
3. The information display will show a green
indicator light, current gap setting and
desired set speed.
4. Take your foot off the accelerator pedal. 5. A lead vehicle graphic will illuminate if
there is a vehicle detected in front of you.
Note: When adaptive cruise control is active,
the speedometer may vary slightly from the
set speed displayed in the information
display. Following a Vehicle WARNINGS
When following a vehicle in front of
you, your vehicle will not decelerate
automatically to a stop, nor will 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. Failing to do so
may result in a crash, serious injury or death. Note:
The brakes may emit a sound when
modulated by the adaptive cruise control
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. The distance
setting is adjustable.

Changing the Set Speed
•
Accelerate or brake to the desired speed,
then press and release SET+.
• Press and hold
SET+ or SET- until the
desired set speed shows on the
information display. The vehicle speed
will gradually change to the selected
speed.
• Press and release SET+ or SET-. The set
speed will change in approximately 1 mph
(2 km/h) increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed will display continuously in the
information display while the system is active.
Resuming the Set Speed
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Press and release
RES. The vehicle will
return to the previously set speed. The set
speed will display continuously in the
information display while the system is active. Low Speed Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An audible
alarm will sound and the automatic braking
releases if the vehicle drops below this
speed.
Hilly Condition Usage
Note:
An audible alarm will sound and the
system will shut down if it is applying brakes
for an extended period of time. This allows
the brakes to cool down. The system will
function normally again when the brakes
have cooled down.
You should select a lower gear position
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
them from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system. Press and release OFF
or turn off the ignition.
Detection Issues
The radar sensor has a limited field of vision.
It may not detect vehicles at all or detect a
vehicle later than expected in some
situations. The lead vehicle graphic will not
illuminate if the system does not detect a
vehicle in front of you.
217
MKZ Hybrid (), enUSA 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. The driver should stay alert
and intervene 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 detections. See an authorized
dealer to have the radar checked for proper
coverage and operation. System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
•
a blocked sensor
• high brake temperature
• a failure in the system or a related
system.
Blocked Sensor WARNINGS
Do not use the system when towing a
trailer with electronic 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. The system does operate with
non-electronic trailer brake controllers, such
as over-run or surge brakes.

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
(page 109).
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 (page 109). Blocked Sensors 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.

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).
