WAF0773X
The AEB with pedestrian detection sys-
tem uses a radar sensorlocated on the
front of the vehicle to measure the
distance to the vehicle ahead in the same
lane.
For pedestrians, the AEB system uses a
camera
installed behind the windshield
in addition to the radar sensor.WAF0740X

AEB WITH PEDESTRIAN DETECTION
SYSTEM OPERATION
The AEB with pedestrian detection sys-
tem will function when your vehicle is
driven at speeds above approximately 3
MPH (5 km/h).

serious injury or death.
.The AEB with pedestrian detec-
tion system cannot detect all
vehicles or pedestrians under all
conditions.
. The AEB with pedestrian detec-
tion system does not detect the
following:
— Pedestrians that are small (for
example, children), in a sitting
position, operating toys/ska-
teboards, on scooters or in
wheelchairs, or not in an up-
right standing or walking po-
sition.
— Animals of any size.
— Obstacles (for example, cargo or debris) on the roadway or
roadside.
— Oncoming or crossing vehi- cles.
— Vehicles where the tires are difficult to see or the shape of
the rear of the vehicle is un-
clear or obstructed.
— Parked vehicles.
. The AEB with pedestrian detec-
tion system has some perfor-
mance limitations. — If a stationary vehicle is in the
vehicle’s path, the system will
not function when the vehicle
approaches the stationary ve-
hicle at speeds over approxi-
mately 50 MPH (80 km/h).
— Pedestrian detection will not function when the vehicle is
driven at speeds over ap-
proximately 37 MPH (60
km/h) or below approxi-
mately 6 MPH (10 km/h).
. For pedestrians, the AEB with
pedestrian detection system will
not issue the first warning.
. The AEB with pedestrian detec-
tion 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,
sunlight or high beams) en-
ters the front camera or a
sudden change in brightness
occurs (for example, entering
a tunnel or driving in light-
ning).
— In dark or dimly lit conditions, such as at night or in tunnels,
including cases where your
vehicle’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, sud-
den acceleration or decelera-
tion).

— When your vehicle or the ve-hicle or pedestrian ahead
moves quickly or significantly
such that the system 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, sud-
den acceleration or decelera-
tion).
— When the vehicle or pedes- trian is offset from the vehi-
cle’s forward path.
— If the speed difference be- tween the two vehicles is
small.
— The pedestrian’s profile is par- tially obscured or unidentifi-
able; for example, due to
transporting luggage, push-
ing a stroller, wearing 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, ex-
tremely low or high clearance
heights, or unusual cargo
loading or is narrow (for ex-
ample, a motorcycle).
— When the vehicle or pedes- trian is located near a traffic
sign, a reflective area (for ex-
ample, water on road), or is in
a shadow.
— When multiple pedestrians are grouped together.
— When the view of the pedes- trian is obscured by a vehicle
or other object.
— While towing a trailer or other vehicle.
. The system performance may be
degraded in the following condi-
tions:
— 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 auto-
matically check the sensor (radar
and camera)’s functionality, with-
in certain 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 sys-
tem 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 condi-
tions, the AEB with pedestrian
detection system may unexpect-
edly apply partial braking. When
acceleration is necessary, de-
press the accelerator pedal to
override the system.
. The AEB with pedestrian detec-
tion system may operate when a
pattern, object, shadow or lights
are detected that are similar to
the outline of vehicles or pedes-
trians, or if they are the same size
and position as a vehicle or mo-
torcycle’s tail lights.

SSD0253
When driving on some roads, such as
winding, 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
maneuver 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 unexpectedly. You
will have to manually control the proper
distance away from the vehicle travel-
ing ahead.SYSTEM TEMPORARILY UNAVAIL-
