2021 FORD EXPEDITION sensor

WHAT IS AUTOMATIC HIGH
BEAM CONTROL
The system turns on high beams if it is dark
enough and no other traffic is present. If it
detects an approaching vehicle
’s
headlamps or tail lamps, or street lighting
ahead, the system turns the high beams
off. Low beams remain on.
A camera sensor, centrally mounted
behind the windshield of your vehicle,
continuously monitors conditions to turn
the high beams on and off.
SWITCHING AUTOMATIC HIGH
BEAM CONTROL ON AND OFF
Switch the system on or off using the
information display. See General
Information (page 119).
Activating the Automatic High
Beam Control Switch the lighting control to the
autolamps position to activate.
See
Autolamps (page 99).
Note: Automatic high beams are not
available when autolamps are not turned
on.
When active, the high beams turn on if:
• The ambient light level is low enough.
• There is no traffic in front of your
vehicle.
• The vehicle speed is greater than
approximately
32 mph (52 km/h).
When active, the high beams turn off if:
• The ambient light level is high enough
that high beams are not required.
• The system detects an approaching
vehicle's headlamps or tail lamps.
• The system detects severe rain, snow
or fog. •
The camera is blocked.
• The vehicle speed falls below
approximately
27 mph (44 km/h).
Note: The deactivation speed is lower on
curves.
Note: High beam reactivation may be
delayed in certain curvy road situations.
Note: The system may not operate properly
if the sensor is blocked. Keep the windshield
free from obstruction or damage.
Note: The system may not operate properly
in cold or inclement conditions. You can
switch on the high beams by overriding the
system.
Note: If the system detects a blockage, for
example bird droppings, bug splatter, snow
or ice, the system goes into low beam mode
until you clear the blockage. A message may
appear in the information display if the
camera is blocked.
Note: Using much larger tires or equipping
vehicle accessories such as snowplows can
modify your vehicle's ride height and
degrade automatic high beam control
performance.
AUTOMATIC HIGH BEAM
CONTROL INDICATORS The indicator illuminates to
confirm when the system is
ready to assist.
OVERRIDING AUTOMATIC
HIGH BEAM CONTROL WARNING:
The system does not
relieve you of your responsibility to drive
with due care and attention. You may
need to override the system if it does not
turn the high beams on or off.

Note:
If you use the power-folding control
to fold the mirrors on demand and the auto
fold feature is switched on through the
information display, you must use the
power-folding control again to unfold them.
Loose Mirror
If your power-folding mirrors are manually
folded, they may not work properly even
after you re-position them. You need to
reset them if:
• The mirrors vibrate when you drive.
• The mirrors feel loose.
• The mirrors do not stay in the folded or
unfolded position.
• One of the mirrors is not in its normal
driving position.
To reset the power-fold feature, use the
power-folding mirror control to fold and
unfold the mirrors. You may hear a loud
noise as you reset the power-folding
mirrors. This sound is normal. Repeat this
process as needed each time the mirrors
are manually folded.

could result in the loss of control of your
vehicle, serious personal injury or death.
Note: Do not clean the mirror housing or
glass with harsh abrasives, fuel or other
petroleum-based cleaning products.
You can adjust the interior mirror to your
preference. Some mirrors also have a
second pivot point. This lets you move the
mirror head up or down and from side to
side.
Manual Dimming Mirror
Pull the tab below the mirror toward you
to reduce the effect of bright light from
behind.
Automatic Dimming Mirror (If Equipped)
Note: Do not block the sensors on the front
and back of the mirror. A rear center
passenger or raised rear center head
restraint may also block light from reaching
the sensor.
