The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. 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. WARNING:
The system will turn off
if a malfunction is apparent. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. Auto Hold uses your vehicle's brakes to hold
your vehicle at a stop once your vehicle has
reached a standstill condition. For example,
Auto Hold can assist you while stopping at
traffic lights or while in traffic jams by holding
the brake pressure for you once you bring
your vehicle to a stop.
Switch Auto Hold off during vehicle or trailer
towing.
Note:
In case of a malfunction in the system
while Auto Hold actively holds the vehicle
(for example, low power supply), a message
appears in the information display asking
you to press the brake pedal. If you see this
message, press the brake pedal
immediately.
Note: Auto Hold only activates if the system
recognizes it is applying enough brake
pressure. On a steep hill or incline, you may
need to make sure the brake pedal is
pressed sufficiently to activate the Auto Hold
system.

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
110).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off or
on.
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
WARNING: 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. WARNING:
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:
205
MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Stability Control

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 204). Vehicle without stability control
skidding off its intended route.

B USING STABILITY CONTROL
The system automatically turns on each time
you switch the ignition on.
The electronic stability control portion of the
system disables when the transmission is in
reverse (R) or, on some models, if you press
and hold the stability control button for more
than five seconds when you apply the brakes
and the vehicle is at a stop.
You can switch the traction control system
off or on independently.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
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. WARNING:
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. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground.
Note: If your vehicle has MyKey™, the sensing
system cannot be switched off when a
MyKey™ is present.
See Principle of
Operation (page 62). Note:
Keep the sensors 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 you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer 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.
You can switch the system 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 110). If your vehicle has a
parking aid button, you can switch the
system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 121).
REAR PARKING AID WARNING:
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.
208
MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Parking Aids

Note:
Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
Note: If you switch traction control off, the
side sensing system also turns off.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
Note: The system does not detect an object
that is moving toward the side of your
vehicle, for example another vehicle moving
at low speed, if it does not pass a front or
rear sensor.
The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as your
vehicle moves past them.
The sensors are on the front and rear
bumpers. The system may not function if:
•
You switch the ignition on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.
To reinitialize the system, you may have to
drive your vehicle approximately 10 ft (3 m). The sensor coverage area is up to
24 in
(60 cm) from the side of your vehicle. When the system detects an object within
the coverage area and the driving path of
your vehicle, an audible warning sounds. As
the object moves closer to your vehicle, the
rate of the tone increases.
Object Distance Indicator
(If Equipped)
The system provides object distance
indication through the information display.
213
MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Parking AidsE190458 E190459

•
As the distance to the object decreases,
the indicator blocks illuminate and move
toward the vehicle icon.
• If there is no object detected, the
distance indicator blocks are gray.
When you shift into reverse (R), the system
provides audible warnings and visual
indication when detected objects are within
24 in (60 cm) and are inside the driving path
of your vehicle. When you stop your vehicle,
the audible warnings turn off after two
seconds.
When you shift into any forward gear, the
system provides audible warnings and visual
indication when your vehicle is moving at a
speed of approximately
5 mph (8 km/h) or
below and the system detects an object
within the detection zone. When you stop
your vehicle, the audible warnings turn off
after two seconds and visual indication turns
off after four seconds. When you shift into neutral (N), the system
only provides visual indication if your vehicle
is moving at a speed of approximately 5 mph
(8 km/h)
or below. For example, your vehicle
is moving on a slope, and the system detects
an object moving toward your vehicle. When
you stop your vehicle, visual indication turns
off after four seconds.
If the system is not available, the side
distance indicator blocks do not display.
ACTIVE PARK ASSIST
(IF EQUIPPED) WARNING: You must remain in your
vehicle when the system turns on. 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. WARNING:
The sensors may not
detect objects in heavy rain or other
conditions that cause interference. WARNING:
Active park assist does
not apply the brakes under any
circumstances. 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.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
