A message displays if something obstructs
the radar signals from the sensor. The
sensor is located behind a fascia cover
near the driver side of the lower grille. The
system cannot detect a vehicle ahead and
will not function when something obstructs
the radar signals. The following table lists
possible causes and actions for this
message displaying.
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 no
longer obstructed
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
be blocked. This can happen, for example,
when driving in sparse rural or desert
environments. A false blocked condition
will either self clear or clear after a key
cycle.
Switching to Normal Cruise
Control
WARNING
Normal cruise control will not brake
due to slower vehicles. Always be
aware of which mode is selected and
apply the brakes when necessary.
You can manually change from adaptive
cruise control to normal cruise control
through the information display.
E71340
The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting will not display, the system will not
automatically respond to lead vehicles and
automatic braking will activate. The
system defaults to adaptive cruise control
when you start the vehicle.
ECO Cruise Control
This feature saves vehicle energy by
relaxing acceleration compared to
standard cruise control. For example, your
vehicle may temporarily lose speed when
going uphill.
ECO
will appear in the
information display when you activate ECO
cruise control. It can be switched on or off
in the information display. See
General
Information
