Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. When the
radar signals are obstructed, a
vehicle ahead cannot be detected
and the ACC will not function. The
following table lists possible causes
and actions for this message being displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some way
Clean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the display
Wait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain or snow is interfering
with the radar signals
Do not use ACC in these
conditions because it may not
detect, warn, or respond to
potential collisions.
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals
Do not use ACC in these
conditions because it may not
detect, warn, or respond to
potential collisions.
WARNING: Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
