FEB WITH PEDESTRIAN DETEC-
TION SYSTEM OPERATION
The FEB with Pedestrian Detection system
will function when your vehicle is driven at
speeds above approximately 3 MPH (5
km/h).
For the pedestrian detection function, the
FEB with Pedestrian Detection system op-
erates at speeds between 6 – 37 MPH (10 –
60 km/h).
If a risk of a forward collision is detected, the
FEB with Pedestrian Detection system will
firstly provide the warning to the driver by
flashing the vehicle ahead detection indica-
tor (yellow) in the vehicle information display
and providing an audible alert. In addition,
the system applies partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
with Pedestrian Detection system detects
that there is still the possibility of a forward
collision, the system will automatically in-
crease the braking force.
If the driver does not take action, the FEB
with Pedestrian Detection system issues the
second visual (flashing) (red) and audible
warning. Then the system applies partial
braking.
If the risk of a collision becomes imminent,
the FEB with Pedestrian Detection system

applies harder braking automatically.
While the FEB with Pedestrian Detection
system is operating, you may hear the sound
of brake operation. This is normal and
indicates that the FEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB with
Pedestrian Detection system.
Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences of a
collision should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB with Pe-
destrian Detection system will function later
or will not function.
The automatic braking will cease under the
following conditions:
.When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle,
pedestrian detected ahead.
If the FEB with Pedestrian Detection system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2 seconds before the brakes are released.
When the brake pedal is depressed while the
brake is applied by the system, you may feel
the pedal effort is changed and may hear a
sound and vibration noise. This is normal and
does not indicate a malfunction. In addition,
the braking force can be increased by adding
the pedal effort.

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 FEB with Pedestrian Detection
system does not detect the following:
— Pedestrians that are small (for example, children), in a sitting
position, operating toys/skate-
boards, on scooters or in wheel-
chairs, or not in an upright
standing or walking position.
— Animals of any size.
— Obstacles (for example, cargo or debris) on the roadway or road-
side.
— Oncoming or crossing vehicles.
— Vehicles where the tires are diffi- cult to see or the shape of the rear
of the vehicle is unclear or ob-
structed.
— Parked vehicles.
. The FEB with Pedestrian Detection
system has some performance limita-
tions.
— If a stationary vehicle is in the vehicle’s path, the system will not function when the vehicle ap-
proaches the stationary vehicle
at speeds over approximately 50
MPH (80 km/h).
— Pedestrian detection will not function when the vehicle is driven
at speeds over approximately 37
MPH (60 km/h) or below ap-
proximately 6 MPH (10 km/h).
. For pedestrians, the FEB with Pedes-
trian Detection system will not issue
the first warning.
. The FEB with Pedestrian Detection
system may not function properly or
detect a vehicle or pedestrian ahead
in the following conditions:
— In poor visibility conditions (such as rain, snow, fog, dust storms,
sand storms, smoke, and road
spray from other vehicles).
— If dirt, ice, snow, fog or other material is covering the radar
sensor area or camera area of
the windshield.
— If strong light (for example, sun- light or high beams) enters the
front camera or a sudden change
in brightness occurs (for example,
entering a tunnel or driving in
lightning). — In dark or dimly lit conditions,
such as at night or in tunnels,
including cases where your vehi-
cle’s headlights are off or dim, or
the tail lights of the vehicle ahead
are off.
— When the direction of the camera is misaligned.
— When driving on a steep downhill slope, on roads with sharp curves,
and/or bumpy or dirt roads.
— If there is interference by other radar sources.
— When your vehicle’s position or movement is changed quickly or
significantly (for example, lane
change, turning vehicle, abrupt
steering, sudden acceleration or
deceleration).
— When your vehicle or the vehicle or pedestrian ahead moves quickly
or significantly such that the sys-
tem cannot detect and react in
time (for example, pedestrian
moving quickly toward the vehicle
at close range, vehicle cutting in,
changing lanes, making a turn,
steering abruptly, sudden accel-
eration or deceleration).
Starting and driving5-99

5-100Starting and driving
— When the vehicle or pedestrian isoffset from the vehicle’s forward
path.
— If the speed difference between the two vehicles is small.
— The pedestrian’s profile is par- tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
— There is poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
— For approximately 15 seconds after starting the engine
— If the vehicle ahead has a unique or unusual shape, extremely low
or high clearance heights, or unu-
sual cargo loading or is narrow
(for example, a motorcycle).
— When the vehicle or pedestrian is located near a traffic sign, a
reflective area (for example,
water on road), or is in a shadow. — When multiple pedestrians are
grouped together.
— When the view of the pedestrian is obscured by a vehicle or other
object.
— While towing a trailer or other vehicle.
. The system performance may be
degraded 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
cargo 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 some forms of obstruction of
the sensor area such as 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.
. The FEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of
vehicles or pedestrians, or if they
are the same size and position as a
vehicle or motorcycle’s tail lights.
. The system may keep operating when
the vehicle ahead is turning right or
left.
. The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
. Depending on the road shape (curved
road, entrance and exit of the curve,
winding road, lane regulation, under
construction, etc.), the system may
operate temporarily for the oncoming
vehicle in front of your vehicle.

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction or on a slope,
the sensor may detect vehicles in a different
lane, or may temporarily not detect a vehicle
traveling ahead. This may cause the 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 system
indicator and sounding the chime unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.SYSTEM TEMPORARILY UNA-
