2015 FORD FOCUS sensor

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 detect a
parking space The system does not offer a particular space
Something may be contacting the front bumper or side sensors
There is not enough room on both sides of your vehicle in order to park
There is not enough space for the parking maneuver on the opposite side of the parking
space
Your vehicle is farther than 5 ft (1.5 m) from the parking space
Your vehicle is closer than 16 in. (40 cm) from neighboring parked vehicles
The transmission is in Reverse (R); your vehicle must be moving forward to detect a
parking space
Your vehicle is going faster than 20 mph (35 km/h) 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 when
Reverse [R] is 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
You pulled your vehicle 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 (not inflated correctly, improper
size, or of different sizes)
A repair or alteration has changed detection capabilities

LANE KEEPING SYSTEM (If
Equipped) WARNINGS
The system does not relieve you of
your responsibility to drive with due
care and attention.
At all times you are responsible for
controlling your vehicle, supervising
the system and intervening if
required. If the sensor becomes blocked the
system may not function.
In cold and severe weather
conditions the system may not
function. Rain, snow, spray can all
limit sensor performance. Large contrasts in lighting can limit
sensor performance.
The system will not operate if the
sensor cannot track the road lane
markings.
Do not carry out windshield repairs
in the immediate area surrounding
the sensor.
Note:
The system works above
40 mph
(64 km/h).
Note: The system works as long as the
camera can detect one lane marking.
Note: The system may not function if the
camera is blocked or there is damage to the
windshield.
Note: When Aid mode is on and the system
detects no steering activity for a short
period, the system will alert you to put your
hands on the steering wheel. The system
may detect a light grip or touch on the
steering wheel as hands off driving. The system notifies you to stay in your lane
through the steering system and the
instrument cluster display when the front
camera detects an unintentional drift out
of your lane is likely to occur. The system
automatically detects and tracks the road
lane markings using a camera mounted
behind the interior rear view mirror.
Switching the System On and Off
Note:
The system on or off setting is stored
until it is manually changed, unless a MyKey
is detected. If the system detects a MyKey
it defaults to on and the mode is set to Alert.
Note: If a MyKey is detected, pressing the
button will not affect the on or off status of
the system. You can only change the Mode
and Intensity settings. Press the button located on the
left steering wheel stalk to
switch the system on or off.
System Settings
The system has optional setting menus
available. To view or adjust the settings,
See General Information (page 96). The
system stores the last-known selection for
each of these settings. You do not need to
readjust your settings each time you turn
on the system.
Mode: This setting allows you to select
which of the system features you can
enable.

BLIND SPOT INFORMATION
SYSTEM (If Equipped)
Blind Spot Information System
(BLIS ™) with Cross Traffic Alert
(If Equipped) WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior
and exterior mirrors and looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. The Blind Spot Information System is
designed to aid you in detecting vehicles
that may have entered the blind spot zone
(A). The detection area is on both sides of
your vehicle, extending rearward from the
exterior mirrors to approximately
10 ft
(3 m) beyond the bumper. The system is
designed to alert you if certain vehicles
enter the blind spot zone while driving.
Cross Traffic Alert is designed to warn you
of vehicles approaching from the sides
when the transmission is in reverse (R). Note:
The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees, etc.). It's only designed to
alert you to vehicles in the blind zones.
Note: When a vehicle passes quickly
through the blind zone, typically fewer than
two seconds, the system does not trigger.
Using the Systems
The Blind Spot Information System turns
on when you start the engine and you drive
you vehicle forward above
5 mph
(8 km/h); it remains on while the
transmission is in drive (D) or neutral (N).
If shifted out of drive (D) or neutral (N),
the system enters cross traffic alert mode.
Once shifted back into drive (D), the Blind
Spot Information System turns back on
when you drive your vehicle above
5 mph
(8 km/h).
Note: The Blind Spot Information System
does not function in reverse (R) or park (P)
or provide any additional warning when a
turn signal is on.
Note: Cross Traffic Alert is designed to
detect approaching vehicles from up to 46 ft
(14 m)
away, though coverage decreases
when the sensors are blocked. Reversing
slowly helps increase the coverage area and
effectiveness.
Note: For manual transmission vehicles,
the Cross Traffic Alert will be active only if
the transmission is in reverse (R). If your
vehicle is rolling backwards and the
transmission is not in reverse (R) then Cross
Traffic Alert will not be active.

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. In this first example, the left sensor is only
partially obstructed; zone coverage is
nearly maximized.
168
Focus (CDH), enUSA, First Printing Driving AidsE142440

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 and Messages
The Blind Spot Information and Cross
Traffic Alert systems illuminate a yellow
alert indicator in the outside mirror on the
side of your vehicle the approaching
vehicle is coming from.
Note:
The alert indicator dims when the
system detects nighttime darkness. Cross Traffic Alert also sounds a series of
tones 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 153).
System Sensors WARNING
Just prior to the system recognizing
a blocked condition and alerting the
driver, the number of missed objects
will increase. To help avoid injuries, NEVER
use the Blind Spot Information System as
a replacement for using the side and rear
view mirrors and looking over your shoulder
before changing lanes. The Blind Spot
Information System is not a replacement
for careful driving. Note:
It is possible to get a blockage
warning with no blockage present; this is
rare and known as a false blockage warning.
A false blocked condition either
self-corrects or clears after a key cycle.
169
Focus (CDH), enUSA, First Printing Driving AidsE142441 E142442

The system uses radar sensors which 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.
If the system detects a degraded
performance condition, a message warning
of a blocked sensor or low visibility will
appear in the information display along
with a warning indicator. You can clear the
information display warning but the
warning indicator will remain illuminated.
When you remove a blockage, you can
reset the system in two ways:
•
While driving, the system detects at
least two objects.
• You cycle the ignition from on to off
and then back on.
If the blockage is still present after the key
cycle and driving in traffic, check again for
a blockage. Reasons for messages being displayed
Clean the fascia area in
front of the radar or remove the obstruction.
The radar
surface is dirty or
obstructed
Drive normally in traffic for
a few minutes to allow the radar to detect passing
vehicles so it can clear the blocked state.
The radar
surface is
not dirty or
obstructed
No action required. Thesystem automatically
resets to an unblocked
state once the rainfall or
snowfall rate decreases or
stops. Do not use the Blind
Spot Information System or Cross Traffic Alert in these conditions.
Heavy rain-
fall or
snowfall
interferes with the radar
signals
System Limitations
The Blind Spot Information and Cross
Traffic Alert systems do have their
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 Blind Spot Information System:
• Certain maneuvering of vehicles
entering and exiting the blind zone.
• Vehicles passing through the blind zone
at very fast rates.
• When several vehicles forming a
convoy pass through the blind zone.
The following are other situations that may
limit the Cross Traffic Alert system:
• Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 15 mph (24 km/h).
170
Focus (CDH), enUSA, First Printing Driving AidsE142443

•
Driving in reverse faster than 5 mph
(8 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a factory equipped
tow bar and it is towing a trailer, the sensors
will detect the trailer and turn the Blind Spot
Information and Cross Traffic Alert systems
off to avoid false alerts. For non-factory
equipped tow bars, you may want to turn
the Blind Spot Information System off
manually.
There may be certain instances when there
is a false alert by either the Blind Spot
Information or the Cross Traffic Alert
systems 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.
System Errors
If either system senses a problem with the
left or right sensor, the Blind Spot
Information System warning indicator will
illuminate and a message will appear in
the information display.
All other system faults will display only
with a message in the information display.
See
Information Messages (page 99).
Switching the Systems Off and On
You can temporarily switch off one or both
systems in the information display. See
(page
96). When you switch off the Blind
Spot Information System, you will not
receive alerts and the information display
will display a system off message.
Note: The Cross Traffic Alert system always
switches on whenever the ignition is
switched on. However, the Blind Spot
Information System will remember the last
selected on or off setting. One or both systems cannot be switched
off when MyKey is used.
See Principle of
Operation (page 58).
You can also have one or both systems
switched off permanently at an authorized
dealer. Once switched off, the system can
only be switched back on at an authorized
dealer.
ECO MODE
This system assists you in driving more
efficiently by constantly monitoring
characteristics of gear changing,
anticipation of traffic conditions and
speeds while driving.
The value of these characteristics is
represented by petals shown in the display,
with five petals being the most efficient.
The more efficiently you drive, the better
the rating, and the better your vehicle's
overall fuel economy.
Note: These efficiency values do not result
in a defined fuel consumption figure. It might
vary as it is not only related to these driving
habits, but also influenced by many other
factors such as short trips and cold starts.
Note: Frequent short trips, where the engine
does not fully warm up, will also increase
fuel consumption
The system is accessed using the
information display control. See
(page
96).
