Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
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.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is
possible to get a blockage warning and not
have a blockage. This can happen, for
example, when driving in sparse rural or
desert environments. A false blocked
condition either self clears or clears after
a key cycle.
Switching to Normal Cruise
Control
WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have selected and apply
the brakes when necessary.
You can manually change from adaptive
cruise control to normal cruise control
through the information display. See
E71340
The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles
and automatic braking remains active to
maintain set speed. The system recalls its
last setting when you start your vehicle.
