NOTE:
•The I-FCW system will be automatically
turned on when the engine is restarted.
• The I-FCW system is integrated into the AEB with Pedestrian Detection system.
There is not a separate selection in the
vehicle information display for the
I-FCW system. When the AEB with Pe-
destrian Detection is turned off, the
I-FCW system is also turned off.

WARNING
Listed below are the system limitations
for the I-FCW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The I-FCW system cannot detect all
vehicles under all conditions. •
The radar sensor does not detect the
following objects:
– Pedestrians, animals or obstacles
in the roadway
– Oncoming vehicles
– Crossing vehicles
• (Illustration A) The I-FCW system
does not function when a vehicle
ahead is a narrow vehicle, such as a
motorcycle. •
The radar sensor may not detect a
vehicle ahead in the following condi-
tions:
– Snow or heavy rain
– Dirt, ice, snow or other material
covering the radar sensor.
– Interference by other radar
sources.
– Snow or road spray from traveling
vehicles.
– Driving in a tunnel
– Towing a trailer

•(Illustration B) When the vehicle
ahead is being towed.
• (Illustration C) When the distance to
the vehicle ahead is too close, the
beam of the radar sensor is
obstructed.
• (Illustration D) When driving on a
steep downhill slope or roads with
sharp curves.
• The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The sys-
tem may not detect some forms of
obstruction of the sensor area such
as ice, snow, stickers, etc. In these
cases, the system may not be able to
warn the driver properly. Be sure that
you check, clean and clear the sensor
area regularly.
• Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
I-FCW system to work inappropriately.The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver or traveling position in the lane, etc.)
or vehicle condition.
If this occurs, the sys-
tem may warn you by blinking the ve-
hicle ahead detection indicator and
sounding the chime unexpectedly. You
will have to manually control the proper
distance away from the vehicle traveling
ahead.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interfer-
ence from another radar source, making it
impossible to detect a vehicle ahead, the
I-FCW system is automatically turned off.
The AEB with Pedestrian Detection system
OFF warning light (orange) will flash.
Action to take
When the above conditions no longer exist,
the I-FCW system will resume automati-
cally.
Condition B
When there is inclement weather (rain, fog,
snow, etc.) blocking the front radar sensor,
the I-FCW system will automatically be
canceled and the “Forward Driving Aids
temporarily disabled Front Sensor Blocked
See Owner’s Manual” warning message will
appear in the vehicle information display.
