sensor FORD EXPLORER 2021 Service Manual

The radar sensor is in the lower grille.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Note: Keep the front of your vehicle free of
dirt, metal badges or objects. Vehicle front
protectors, aftermarket lights, additional
paint or plastic coatings could also degrade
sensor performance.
A message displays if something obstructs
the camera or the sensor. When something
blocks the sensor, the system cannot
detect a vehicle ahead and does not
function. See Adaptive Cruise Control
– Information Messages (page 256).
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 image does
not illuminate if the system does not
detect a vehicle in front of you. 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.
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.

spot zone. The detection area is on both
sides of your vehicle, extending rearward
from the exterior mirrors to approximately
13 ft (4 m) beyond the rear bumper. The
detection area extends to approximately
59 ft (18 m)
beyond the rear bumper when
the vehicle speed is greater than 30 mph
(48 km/h) to alert you of faster
approaching vehicles.
Note: The system does not prevent contact
with other vehicles. It does not detect
parked vehicles, pedestrians, animals or
other infrastructures.
