FEB WITH PEDESTRIAN DETEC-
TION SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the FEB with pedestrian detection
system. Failure to operate the vehicle in
accordance with these system limita-
tions could result in serious injury or
death.
.
The FEB with pedestrian detection
system cannot detect all vehicles or
pedestrians under all conditions. .
The radar sensor FEB with pedes-
trian detection system does not de-
tect the following objects:
— Small pedestrians (including small children), animals and cyclists.
— Pedestrians in wheelchairs or using mobile transport such as
scooters, child-operated toys, or
skateboards.
— Pedestrians who are seated or otherwise not in a full upright
standing or walking position.
— Oncoming vehicles
— Crossing vehicles
— Obstacles on the roadside
. The FEB with pedestrian detection
system has some performance limita-
tions.
— If a stationary vehicle is in the vehicle’s path, the FEB with pe-
destrian detection system will not
function when the vehicle is driven
at speeds over approximately 50
MPH (80 km/h).
— For pedestrian detection, the FEB with pedestrian detection
system will not function when
the vehicle is driven at speeds

over approximately 37 MPH (60
km/h) or below approximately 6
MPH (10 km/h).
. The FEB with pedestrian detection
system will not function for pedes-
trians in darkness or in tunnels, even
if there is street lighting in the area.
. For pedestrians, the FEB with pedes-
trian detection system will not issue
the first warning and will not push
the accelerator pedal up.
. The FEB with pedestrian detection
system may not function if the vehi-
cle ahead is narrow (for example a
motorcycle).
. The FEB with pedestrian detection
system may not function if speed
difference between the two vehicles
is too small.
. The radar sensor FEB with pedes-
trian detection system may not func-
tion properly or detect a vehicle
ahead in the following conditions:
— Poor visibility (conditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from
other vehicles)
— Driving on a steep downhill slope or roads with sharp curves. — Driving on a bumpy road surface,
such as an uneven dirt road.
— If dirt, ice, snow or other material is covering the radar sensor area.
— Interference by other radar sources.
— The camera area of windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
— Strong light (for example, sun- light or high beams from oncom-
ing vehicles) enters the front
camera. Strong light causes the
area around the pedestrian to be
cast in a shadow, making it diffi-
cult to see.
— A sudden change in brightness occurs. (For example, when the
vehicle enters or exits a tunnel or a
shaded area or lightning flashes.)
— The poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
— The pedestrian’s profile is par- tially obscured or unidentifiable
due to the pedestrian transport-
ing luggage, wearing bulky or very
loose-fitting clothing or acces- sories.
— When towing a trailer or other vehicle.
. The system performance may de-
grade in the following conditions:
— The vehicle is driven on a slippery road.
— The vehicle is driven on a slope.
— Excessively heavy baggage is loaded in the rear seat or the
luggage area of your vehicle.
. The system is designed to automati-
cally check the sensor (radar and
camera)’s functionality, within cer-
tain limitations. The system may not
detect blockage of sensor areas cov-
ered by ice, snow or stickers, for
example. In these cases, the system
may not be able to warn the driver
properly. Be sure that you check,
clean and clear sensor areas regularly.
. In some road and traffic conditions,
the FEB with pedestrian detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
. Excessive noise will interfere with the
warning chime sound, and the chime

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 vehicle
traveling ahead. This may cause the FEB
with pedestrian detection system to work
inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the system
may warn you by blinking the vehicle ahead
detection indicator and sounding the chime
unexpectedly. You will have to manually
control the proper distance away from the vehicle traveling ahead.
