brake sensor FORD EXPEDITION 2021 User Guide

Park Brake Application
Automatic parking brake application and
cancellation occurs if:
•
You unbuckle the seatbelt and open
the door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three
minutes.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you. 251

Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.
Optimal system performance requires a
clear view of the road by the
windshield-mounted camera.
Optimal performance may not occur if:
• The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
• A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system. Blocked Sensor
A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.

WARNING: The system cannot
help prevent all crashes. Do not rely on
this system to replace driver judgment
and the need to maintain a safe distance
and speed.
Using the Pre-Collision Assist
System
The pre-collision assist system is active at
speeds above approximately
3 mph
(5 km/h) and pedestrian detection is active
at speeds up to
50 mph (80 km/h). If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system is designed to provide three levels
of functionality:
1. Alert
2. Brake Support
3. Active Braking
Alert
: When active, a flashing visual
warning appears and an audible warning
tone sounds.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking.
Brake support does not automatically
apply the brakes. If you press the brake
pedal, the system could apply additional
braking up to maximum braking force, even
if you lightly press the brake pedal.
Active Braking
: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely. Note:
Brake support and active braking are
active at speeds up to
75 mph (120 km/h).
If the vehicle has a radar sensor or adaptive
cruise control, then brake support and active
braking are active up to the maximum speed
of the vehicle.
Note: If you perceive pre-collision assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity leads to
fewer and later system warnings.
Note: The system disables when you select
4x4 low, sand mode, mud/ruts mode or
when you manually disable AdvanceTrac ™.
Distance Indication and Alert
(If
Equipped)
This is a function that provides you with a
graphical indication of the time gap to
other preceding vehicles traveling in the
same direction. The distance indication
and alert screen in the information display
shows one of the following graphics.

Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an
accessory or equivalent. Other
conventional link type chains may
contact and cause damage to the
vehicle's wheel house and/or body.
• Do not install chains on the front tires
as this may interfere with suspension
components.
• Only certain snow cables or chains
have been approved by Ford/Lincoln
as safe for use on your vehicle with the
following tires: 265/70R17 and
275/65R18.
• You should install snow cables or
chains that have been rated as SAE
Class S. •
Install chains securely, verifying that
the chains do not touch any wiring,
brake lines, or fuel lines.
• Do not exceed 31 mph (50 km/h) or
less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.
Note: You should only use tire sealants in
roadside emergencies as they could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function.

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
could 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
could decrease about
3 psi (21 kPa) for a
drop of 30°F (17°C) in ambient
temperature. This lower pressure value
could 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 WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates 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 this vehicle. If you get a flat tire when 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
system sensors.
See Tire Pressure
Monitoring System (page 378). 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.
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.
