ActionCause
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 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 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.
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 not 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 (page 97).
