2017 FORD FOCUS parking sensors

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 54).
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 91).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 95).
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.
151
Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, 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
Parallel Parking, Perpendicular
Parking, Parallel Park Out Assist
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.
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. 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
or perpendicular parking space and
automatically steers your vehicle into the
space (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. Parallel Park Out Assist automatically
steers your vehicle out of a parallel parking
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
enter traffic.
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 (a
pedestrian or cyclist).
• The edge of the neighboring parked
vehicle is high off the ground (for
example, a bus, tow truck or flatbed
truck).
• The weather conditions are poor
(heavy rain, snow, fog, etc).
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 (motorcycle
exhaust, truck air brakes or horns).
Do not use the system if:
• You have attached a foreign object (for
example, a bike rack or trailer) close to
the sensors on the front or rear of your
vehicle.
• You have attached an overhanging
object (for example, a surfboard) to
the roof.
153
Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Parking Aids

•
A foreign object damages or obstructs
the front or rear bumper or side
sensors.
• The correct tire size is not in use on your
vehicle (for example, a mini-spare tire).
Using Active Park Assist - Parallel
Parking Press the active park assist
button to search for a parallel
parking space.
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 indicators are not used, the
system defaults to the passenger side of
your vehicle.Note:
You can also activate the Active Park
Assist system after you have already driven
partially or completely past a parking space.
To do so, press the Active Park button and
the system will inform you if you have
recently passed a suitable parking space.
When the system finds a suitable space,
it displays a message and a tone sounds.
Stop your vehicle and follow the
instructions on the 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 must observe that the selected
space remains clear of obstructions at all
times during the maneuver.
Note: You should drive your vehicle within
5 ft (1.5 m) and as parallel as possible to
the other vehicles while passing a parking
space. Note:
The system always offers the last
detected parking space (for example, if your
vehicle detects multiple spaces while you
are driving, it offers the last one).
Note: If driven above approximately 22 mph
(35 km/h)
, the system shows a message to
alert you to reduce your vehicle speed.
Automatic Steering into Parking Space
Note: If your vehicle speed exceeds
approximately
6 mph (10 km/h) or the
maneuver is interrupted (driver input), the
system switches off and you need to take
full control of your vehicle.
When you shift the transmission into
reverse (R), with your hands off the wheel
(and nothing obstructing its movement),
your vehicle steers itself into the space.
The system displays instructions to move
your vehicle back and forth in the space.

Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Parking AidsE146186 E130107

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 room in the parking space for your vehicle to safely park.
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) or closer than 16 in (0.4 m) away.
Your vehicle is going faster than
22 mph (35 km/h) for parallel and 19 mph (30 km/h)
for perpendicular parking.
You recently disconnected or replaced the battery. After a battery disconnect, the vehicle
must be driven on a straight road for a short period of time. The system does not position the vehicle where I want in the space
Your vehicle is rolling in the opposite direction of the transmission (rolling forward with
reverse [R] selected).
An irregular curb along the parking space prevents the system from aligning your vehicle
properly.
Vehicles or objects bordering the space may not be positioned correctly.
Your vehicle was pulled too far past the parking space.
The tires may not be installed or maintained correctly (not inflated correctly, improper
size, or of different sizes).
A repair or alteration has changed detection capabilities.
A parked vehicle has a high attachment (salt sprayer, snowplow or moving truck bed).
The parking space length or position of parked objects changed after your vehicle passed.
The temperature around your vehicle changes quickly (driving from a heated garage
into the cold, or after leaving a car wash).

Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Parking Aids

Note:
Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
of a blocked sensor will appear in the
information display. Also the BLIS alert
indicators will remain ON and BLIS will no
longer provide any vehicle warnings. You
can clear the information display warning
but the alert indicators will remain
illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
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 Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System with a trailer attached
will cause poor system performance.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See Information
Messages (page 95). Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information (page
91). 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 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).
171
Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, 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 151). 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 169). 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.

Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Driving AidsE142442 E205199

It is recommended that the two
front tires or two rear tires
generally be replaced as a pair.
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, your
tire pressure monitoring system is
malfunctioning. Your replacement
tire might be incompatible with
your TPMS, or some component
of the TPMS may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud, sand, etc., 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 30 mph (56 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 is 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 a tire is
under-inflated or damaged,
deflate it, remove wheel and
replace it with your spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
