2015 FORD F450 brake sensor

2. If the sensors detect that your vehicle
is on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
When you switch the ignition on, the
system automatically turns on. You can
switch the system on or off in the
information display. See General
Information (page 84). The system
remains off until you switch the ignition off.
Note: For vehicles with a manual
transmission, the system can be switched
on or off.
Note: For vehicles with an automatic
transmission, the system cannot be
switched off.

PARKING AID (If Equipped)
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 in reverse on a flat surface at
parking speeds. Traffic control systems,
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 R (Reverse) 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 the 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:
If your vehicle is equipped with
MyKey ™, it is possible to prevent turning
the sensing system off. See MyKey ™
(page
51).
Note: When a trailer is connected to your
vehicle, the Rear Sensing System may
detect the trailer and therefore provide
warnings. It is suggested that the driver
disables the Rear Sensing System when a
trailer is connected to your vehicle to
prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of the
bumper area. The system turns on
automatically whenever the ignition is
switched on.
When receiving a detection warning, the
radio volume is reduced to a
predetermined level. After the warning
goes away, the radio volume returns to the
previous level.
Rear Sensing System
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 fewer than
12 in
(30 cm) away, the warning sounds
continuously. If a stationary or receding
object is detected farther than
12 in
(30 cm) from the side of your vehicle, the
tone sounds for only three seconds. Once
the system detects an object approaching,
the warning sounds again.

Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver's seating position)
or Tire Label located on the B-Pillar
or the edge of the driver's door.
CHANGING A ROAD WHEEL WARNINGS
The use of tire sealant may damage
your tire pressure monitoring system
and should only be used in roadside
emergencies. If you must use a sealant, the
Ford Tire Mobility Kit sealant should be
used. The tire pressure monitoring system
sensor and valve stem on the wheel must
be replaced by an authorized dealer after
use of the sealant. If the tire pressure monitor sensor
becomes damaged, it will no longer
function. See Tire Pressure
Monitoring System (page 283). Note:
If your vehicle is equipped with the
tire pressure monitoring system, the
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
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. If your vehicle is equipped with the tire
pressure monitoring system, have a flat
serviced by an authorized dealer in order
to prevent damage to the system sensors.
See
Tire Pressure Monitoring System
(page 283). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the system
sensor for damage.
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
When driving with one of the dissimilar
spare tires listed above, do not:
