Ford C-MAX Hybrid (2018 year). Manual - part 39

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 52).

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 92).

If a fault is present in the system, a warning
message appears in the information
display.  See Information Messages
(page 99).

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.

Coverage area of up to 6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.

The system detects certain objects while
the transmission is in reverse (R) :
•

Your vehicle is moving toward a
stationary object at a speed of 3 mph
(5 km/h) or less.

•

Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of 3 mph
(5 km/h) or less.

•

Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than 3 mph
(5 km/h).

The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is less than 12 in (30 cm) away
from the bumper.

Obstacle Distance Indicator

 (If

Equipped)

The system provides obstacle distance
indication through the information display.
The distance indicator displays when the
transmission is in reverse (R).

The indicator displays:
•

As the distance to the obstacle
decreases the indicator blocks
illuminate and move towards the
vehicle icon.

•

If there is no obstacle detected, the
distance indicator blocks are grayed
out.

FRONT PARKING AID

 (If Equipped)

The front sensors are active when the
transmission is in any position other than
park (P) and your vehicle is traveling at low
speed.

Coverage area of up to 28 in (70 cm) from
the front bumper. The coverage area
decreases at the outer corners.

When your vehicle approaches an object,
a warning tone sounds. When your vehicle
moves closer to an object, the warning
tone repeat rate increases. The warning
tone sounds continuously when an object
is 12 in (30 cm) or less from the front
bumper.

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 92).  If your
vehicle has a parking aid button, you can
switch the system off by pressing the
button.

Obstacle Distance Indicator

 (If

Equipped)

The system provides obstacle distance
indication through the information display.

The indicator displays:
•

As the distance to the obstacle
decreases, the indicator blocks
illuminate and move towards the
vehicle icon.

•

If the system does not detect an
obstacle, the distance indicator blocks
are grayed out.

If the transmission is in reverse (R), the
front sensing system provides audio
warnings when your vehicle is moving and
the detected obstacle is moving towards
your vehicle.

ACTIVE PARK ASSIST

 (If Equipped)

WARNINGS

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.

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.

WARNINGS

The sensors may not detect objects
in heavy rain or other conditions that
cause interference.

Active park assist does not apply the
brakes under any circumstances.

Note: The blind spot information system
does not detect traffic alongside or behind
your vehicle during an active park assist
maneuver.

The system detects an available parallel
parking space and automatically steers
your vehicle (hands-free) while you control
the accelerator, gearshift and brakes. The
system visually and audibly guides you to
park your vehicle.

If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel or pushing the active park
assist button.

The system may not operate correctly in
any of the following conditions:
•

You use a spare tire or a tire
significantly worn more than the other
tires.

•

One or more tires are improperly
inflated.

•

You try to park on a tight curve.

•

Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.

•

The edge of the neighboring parking
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.

•

The weather conditions are poor.  For
example, during heavy rain, snow or
fog.

Note:  Keep the sensors, located on the
fascia, free from now, ice and large
accumulations of dirt.  Covered sensors can
affect the systems accuracy.  Do not clean
the sensors with sharp objects.

Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference. For
example, motorcycle exhaust, truck air
brakes or horns.

Note: Following a change in tire size, the
system recalibrates and operation may be
impaired for a short time.

Do not use the system if:
•

You have attached a bike rack, trailer
or other object near the sensors on the
front or rear of your vehicle.

•

You have attached an overhanging
object to the roof. For example, a
surfboard.

•

A foreign object damages or obstructs
the sensors.

•

The correct tire size is not in use. For
example, when using a mini-spare tire.

Using Active Park Assist

Press the button to turn the
system on or off.

When driving at a speed less than 22 mph
(35 km/h), the system automatically scans
both sides of your vehicle for an available
parking space. The system displays a
message and a corresponding graphic to
indicate it is searching for a parking space.
Use the direction indicator to select
searching either to the left hand side or
right hand side of your vehicle. If the
direction indicator is not used, the system
defaults to the passenger side of your
vehicle.

When the system finds a suitable space it
displays a message and a tone sounds.
Stop your vehicle and follow the
instructions on the display screen. If your
vehicle is moving very slowly, you may
need to pull forward a short distance
before the system is ready to park.

Note: You can also activate the system
after you drive partially or completely pass
the parking space. To do so, press the active
park assist button and the system informs
you if you recently passed a suitable parking
space.

Note: You must observe that the selected
space remains clear of obstructions at all
times in the maneuver.
