brake sensor FORD FIESTA 2018 Owners Manual

The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system activates, your vehicle
remains stationary on a slope for a few
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 when the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. 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 activates on any slope that
causes your vehicle to roll.
Note:
There is no warning lamp to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. The system activates if the sensors detect that your vehicle is on a slope.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for a few
seconds. This hold time increases if you
are in the process of driving off.
4. Pull away in the normal manner.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle. Vehicles with Automatic Transmission
The system turns on when you switch the
ignition on and you cannot switch the
system off.

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
Always drive with due
care and attention when using and
operating the controls and features on your
vehicle. WARNING:
Only use the Ford
approved trailer wiring kit (including the
trailer wiring module) when towing with
your vehicle. Using generic trailer wiring kits
may prevent the correct operation of the
rear parking sensors (where fitted) and
could damage the electrical systems of
your vehicle. WARNING:
The sensors may not
detect objects in heavy rain or other
conditions that cause interference. WARNING:
The parking aid system
may not prevent contact with small or
moving objects that are close to the
ground. The parking aid system gives an
audible warning when it detects a large
object helping to avoid damage to your
vehicle. To help avoid personal injury you
must take care when using the parking aid
system. Note:
If you use a high pressure spray to
wash your vehicle, only spray the sensors
briefly from a distance not less than
8 in
(20 cm).
Note: If your vehicle has a tow ball arm, the
system is turned off automatically when
trailer lamps (or lighting boards) are
connected to the 13-pin socket through a
Ford approved trailer tow module.
Note: Keep the sensors free from dirt, ice
or snow. Do not clean with sharp objects.
Note: The system may emit false alerts if
it detects a signal using the same frequency
as the sensors or if your vehicle is fully
loaded.
Note: The outer sensors may detect the
side walls of a garage. If the distance
between the outer sensors and the side wall
remains constant for three seconds, the
alert will turn off. As you continue the inner
sensors will detect objects directly behind
your vehicle.
Note: If your vehicle sustains damage to
the bumper or fascia, the sensing zone may
be altered causing inaccurate measure of
obstacles or false alerts.
REAR PARKING AID WARNING:
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.

FRONT PARKING AID (If Equipped)
WARNING:
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. WARNING:
To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The parking aid system
may not prevent contact with small or
moving objects that are close to the
ground. The parking aid system gives an
audible warning when it detects a large
object helping to avoid damage to your
vehicle. To help avoid personal injury you
must take care when using the parking aid
system.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. Blocked
sensors may affect system accuracy. Do
not clean the sensors with sharp objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts.
The system warns you of objects that are
within the detection zone of the bumper
areas. When the parking aid system sounds a
tone, the audio system may reduce the set
volume. When the warning ends, the audio
system will return to the previously set
volume.
The front parking aid sensors automatically
turn on when you shift into reverse (R) or
you press the parking aid button.
Coverage area of up to 31 in (80
cm) from the center of the
bumper and up to 14 in (35 cm)
to the side of the bumper.
A
As your vehicle moves closer an obstacle,
the rate of the audible warning increases.
When the obstacle is less than
12 in
(30 cm) away, the audible warning sounds
continuously. If a stationary or receding
object is detected
12 in (30 cm) or more
from the side of your vehicle, the audible
warning sounds for only three seconds.
Once the system detects an object
approaching, the audible warning sounds
again.

How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL
If you get a flat tire while driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 235). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
an authorized dealer inspect the tire
pressure monitoring system sensor for
damage. Note:
The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full functionality
of the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:
1. T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded
in the sidewall.
2. Full-size dissimilar spare with label
on wheel:
This spare tire has a label
on the wheel that states: THIS WHEEL
AND TIRE ASSEMBLY FOR
TEMPORARY USE ONLY.
3. Full-size dissimilar spare without
label on wheel.
