Operation Manual

If something hits the front of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer as soon as possible.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
• A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system.
Blocked Sensor
A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
The following table lists possible causes and actions for this message displaying
ActionCause
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar in the grille is clean
but the message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, snow or ice on the surface
of the road may interfere with the radar
signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
It is possible to get a blockage warning and not be blocked. A false blocked condition self
clears or clears after a key cycle.
