brake sensor LINCOLN AVIATOR 2023 User Guide

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.

E156130
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.
E255268E255268
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
your vehicle has a radar sensor included
with adaptive cruise control, then brake
support and active braking are active up to
the maximum speed of the vehicle.

Maintenance

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at a
gas station or in your garage), the tire
pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over
20 mph (32 km/h) for the light to turn off after
you have filled your tires to the
recommended inflation pressure.
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 temperaturesignificantly 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 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 tire
pressure monitoring system sensors. See
Tire Pressure Monitoring System (page 447).
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 tire pressure monitoring
system sensor for damage.
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 the vehicle.Dissimilar Spare Wheel and Tire
