2021 FORD F-150 parking sensors

If your vehicle is in any forward gear, the
front parking aid provides audible warnings
and visual indication when your vehicle is
moving at a speed of 5 mph (8 km/h) or
below and the system detects an object
within the detection zone. Once your
vehicle reaches a stop, the visual indication
and audio warning stops after a few
seconds.
If your vehicle is in neutral (N), the front
and rear sensors provide visual indication
only when your vehicle is moving below a
speed of
5 mph (8 km/h) and obstacles
are detected inside the detection areas.
Once your vehicle stops, the visual
indication and audio warning stops after
a few seconds.
LOCATING THE FRONT PARKING
AID SENSORS The front parking aid sensors are in the
front bumper.
FRONT PARKING AID AUDIBLE
WARNINGS
A warning tone sounds when there is an
object within
28 in (70 cm) from the front
bumper. As your vehicle moves closer to
an object, the rate of the tone increases. The warning tone continuously sounds
when an object is 12 in (30 cm) or less from
the front bumper.
Note:
If the detected object is 12 in (30 cm)
or less from your vehicle, visual indication
remains on.

WHAT IS CROSS TRAFFIC
ALERT
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
HOW DOES CROSS TRAFFIC
ALERT WORK
Cross traffic alert detects vehicles that
approach at a speed between 4–
37 mph
(6–60 km/h). Coverage decreases when
the sensors are partially, mostly or fully
obstructed. The sensor on the left-hand side is only
partially obstructed and zone coverage on
the right-hand side is maximized.
Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Note:
Slowly reversing helps increase the
coverage area and effectiveness. CROSS TRAFFIC ALERT

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 to prevent damage to the system
sensors. See Tire Pressure Monitoring
System Precautions (page 560). Replace
the spare tire with a road tire as soon as
possible. When repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Note: The use of tire sealant could damage
your tire pressure monitoring system. Only
use in roadside emergencies.
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, you must mount all
road wheels that come with tire pressure
monitoring sensors on this vehicle.
