Driving on a bumpy road surface, such as
an uneven dirt road
If dirt, ice, snow or other material is cover-
ing the radar sensor area
A complicated-shaped vehicle such as a
car carrier trailer or flatbed truck/trailer is
near the vehicle ahead.
Interference by other radar sources
When your vehicle is towing a trailer, etc.
When excessively heavy baggage is
loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the radar sensor’s operation
within the limitations of the system.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the ICC system to maintain
the selected distance from the vehicle
ahead. A vehicle ahead may move outside
of the detection zone due to its position
within the same lane of travel. Motorcycles
may not be detected in the same lane
ahead if they are traveling offset from the
center line of the lane. A vehicle that is en-
tering the lane ahead may not be detected
until the vehicle has completely moved into
the lane.
If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime. The driver may have
to manually control the proper distance
away from the vehicle traveling ahead.
The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The follow-
ing are some conditions in which the cam-
era may not properly detect a vehicle and
detection of a vehicle ahead may be de-
layed:
Poor visibility (conditions such as rain,
snow, fog, dust storms, sandstorms, and
road spray from other vehicles)
The camera area of the windshield is
fogged up or covered with dirt, water
drops, ice, snow, etc.
Strong light (for example, sunlight or high
beams from oncoming vehicles) enters
the front camera
A sudden change in brightness occurs
(for example, when the vehicle enters or
exits a tunnel or shaded area or lightning
flashes)
Starting and driving 5-89
