2017 FORD C MAX HYBRID parking sensors

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 release automatically
when the engine has sufficient torque to
prevent your vehicle from rolling down the
grade. 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. For vehicles with a manual
transmission, you can switch this feature
off using the information display. See
Information Displays (page 92). The
system will remain on or off depending on
how it was last set.
Note: There is no warning lamp to indicate
the system is either on or off.
Note: If your vehicle is equipped with Auto
Hold, Hill Start Assist will not be available
while Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a complete standstill. Keep the brake pedal
pressed and select an uphill gear (for
example, first (1) when facing uphill or
reverse (R) when facing downhill).
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. Switching the System On and Off
You can switch this feature on or off if your
vehicle is equipped with a manual
transmission and an information display.
See
General Information (page 92). The
system remembers the last setting when
you start your vehicle.
If your vehicle is not equipped with a
manual transmission and an information
display, you cannot turn the system on or
off. When you switch the ignition on, the
system automatically turns on.

PRINCIPLE OF OPERATION
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 on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, 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 your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. 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:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 52).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear sensing
system may detect that add-on device and
therefore provide warnings. It is suggested
that you disable the rear sensing system
when you attach an add-on device to your
vehicle to prevent these warnings.
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 turn the system on or
off by pressing the parking aid
button. If your vehicle does not
have a parking aid button, 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 101).
REAR PARKING AID
The rear parking aid sensors automatically
turn on when you shift into 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 an
object farther than
12 in (30 cm) from the
corners of the bumper, the tone sounds for
only three seconds. If the system detects
an approaching object the warning sounds
again.

C-MAX Energi / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, First Printing Parking AidsE139213

Coverage area of up to 6 ft (1.8 m) from
the rear bumper. There is 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).
FRONT PARKING AID
The front parking aid sensors automatically
turn on when you shift into reverse (R) or
a forward gear.
The front sensors are active when the
transmission is in any position other than
park (P) and the vehicle speed is below
7 mph (12 km/h)
. Coverage area of up to
28 in (70 cm) from
the front bumper. There is decreased
coverage area at the outer corners.
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 of the vehicle.
• Objects detected by the rear sensors
are indicated by a lower pitched tone
from the rear of the vehicle.
• The sensing system reports the
obstacle which is closest to the front
or rear of the vehicle. For example, if
an obstacle is
12 in (30 cm) from the
front of the vehicle and, at the same
time, an obstacle is only
6 in (15 cm)
from the rear of the vehicle, the lower
pitched tone sounds.
• An alternating warning sounds from
the front and rear if there are objects
at both bumpers that are closer than
12 in (30 cm)
.
The system provides warnings 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.

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 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 driver is always responsible for
controlling the vehicle, supervising the
system and intervening if required.
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
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 system may not correctly operate 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, heavy rain, snow, fog and so
forth).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's 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).
Using Active Park Assist Press the button located on the center
console near the transmission selector or
to the right of the center stack. The touch
screen displays a message and a
corresponding graphic to indicate it's
searching for a parking space. Use the turn
signal to indicate which side of the vehicle
you want the system to search on.

Troubleshooting the System
The system does not look for a space
The traction control system may be off.
The transmission is in reverse (R). Your vehicle must be moving forward to be able to
detect a parking space. The system does not offer a particular space
The sensors may be covered (for example snow, ice or dirt buildup). Covered sensors
can affect the system's functionality.
There is not enough space for the parking maneuver on the opposite side of the parking
space.
The parking space is farther than 5 ft (1.5 m) away or closer than 16 in (40 cm).
Your vehicle is going faster than
22 mph (35 km/h).
You may have recently disconnected or replaced the battery. After a battery disconnect,
your vehicle must be driven on a straight road at a speed greater than 12 mph (20 km/h)
for up to 30 seconds. The system does not position the vehicle where I want in the space
The vehicle is rolling in the opposite direction of the transmission (for example, rolling
forward when reverse [R] is selected).
An irregular curb along the parking space prevents the system from aligning the vehicle
properly.
Vehicles or objects bordering the space may not be positioned correctly.
The vehicle was pulled too far past the parking space. The system performs best when
you drive the same distance past the parking space.
The tires may not be installed or maintained correctly (for example, tires not inflated
correctly, improper tire size, or tires of different sizes).
A repair or alteration has changed detection capabilities.

Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See General Information (page
92). 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 Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer. CROSS TRAFFIC ALERT
(If
Equipped) WARNING
To help avoid personal injury, NEVER
use the Cross Traffic Alert system as
a replacement for using the interior
and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross Traffic Alert is not a
replacement for careful driving. Cross Traffic Alert is designed to warn you
of vehicles approaching from the sides
when the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you start
the engine and you shift into reverse (R).
Once shifted out of reverse (R), Cross
Traffic Alert turns off.
Note:
Cross Traffic Alert only functions
while your transmission is in reverse (R).
Cross Traffic Alert is designed to detect
vehicles that approach with a speed up to
37 mph (60 km/h)
. Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Reversing slowly helps
increase the coverage area and
effectiveness.
181
C-MAX Energi / C-MAX Hybrid (CCG) Canada/United States of America, enUSA, First Printing Driving Aids

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.
System Lights, Messages and
Audible Alerts
The Cross Traffic Alert illuminates an
amber alert indicator in the outside mirror
on the side of your vehicle the approaching
vehicle is coming from. Cross Traffic Alert
also sounds an audible alert and a
message appears in the information
display indicating a vehicle is coming from
the right or left. Cross Traffic Alert works
with the reverse sensing system that
sounds its own series of tones. See Rear
Parking Aid (page 168). The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Do not allow mud,
snow or bumper stickers to obstruct these
areas, this can cause degraded system
performance. See
Blind Spot Information System
(page 179). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A
corresponding message appears in the
information display as soon as you shift
the transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
The following are other situations that may
limit the Cross Traffic Alert performance:
• Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than
37 mph
(60 km/h).
• Driving in reverse faster than
7 mph
(12 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Cross Traffic Alert
off. If your vehicle has a tow bar but no
factory equipped trailer tow module, it is
recommended to turn the Cross Traffic Alert
off manually. Operating Cross Traffic Alert
with a trailer attached will cause poor Cross
Traffic Alert performance.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.

The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor
Company may affect the
operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud or sand, do not
rapidly spin the tires; spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds. Do not spin the wheels at
over 34 mph (55 km/h). The
tires may fail and injure a
passenger or bystander. Driving habits have a great deal
to do with your tire mileage and
safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns *Avoid potholes and objects on
the road
*Do not run over curbs or hit the
tire against a curb when parking
Highway Hazards
No matter how carefully you drive
there
’s always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect your tire or vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If you cannot
detect a cause, have the vehicle
towed to the nearest repair facility
or tire dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you’re
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
