The AEB system operates at speeds above
approximately 3 mph (5 km/h). For the pe-
destrian detection function, the system
operates at speeds between6–37mph(10
– 60 km/h).
If a risk of a forward collision is detected,
the AEB with Pedestrian Detection system
will firstly provide the warning to the driver
by flashing the vehicle ahead detection in-
dicator (yellow) in the vehicle information
display and providing an audible alert. If the
driver applies the brakes quickly and force-
fully af ter the warning, and the AEB with
Pedestrian Detection system detects that
there is still the possibility of a forward col-
lision, the system will automatically in-
crease the braking force.
If the driver does not take action, the AEB
with Pedestrian Detection system issues
the second visual (flashing) (red and white)
and audible warning. If the driver releases
the accelerator pedal, then the system ap-
plies partial braking. If the risk of a collision
becomes imminent, the AEB with Pedes-
trian Detection system applies harder
braking automatically.

5-94Starting and driving

While the AEB with Pedestrian Detection
system is operating, you may hear the
sound of brake operation. This is normal
and indicates that the AEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB with
Pedestrian Detection system will function
later or will not function.The automatic braking will cease under the
following conditions:
• When the steering wheel is turned to
avoid a collision.
• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.

AEB WITH PEDESTRIAN
DETECTION SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB with Pedestrian Detection
system. Failure to operate the vehicle in
accordance with these system limita-
tions could result in serious injury or
death.
• The AEB with Pedestrian Detection
system cannot detect all vehicles or
pedestrians under all conditions.
• The AEB with Pedestrian Detection
system does not detect the follow-
ing:
– Pedestrians that are small (for ex- ample, children), in a sitting posi-
tion, operating toys/skateboards,
on scooters or in wheelchairs, or
not in an upright standing or
walking position.
– Animals of any size.
– Obstacles (for example, cargo or debris) on the roadway or
roadside.
– Oncoming or crossing vehicles.
LSD3788
For vehicles with the 4.2 inch meter display
Starting and driving5-97

– Vehicles where the tires are diffi-cult to see or the shape of the rear
of the vehicle is unclear or
obstructed.
– Parked vehicles.
• The AEB with Pedestrian Detection
system has some performance limi-
tations.
– If a stationary vehicle is in the ve-
hicle’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 approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10km/h).
• For pedestrians, the AEB with Pedes-
trian Detection system will not issue
the first warning. •
The AEB with Pedestrian Detection
system may not function properly or
detect a vehicle or pedestrians
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 ma-
terial is covering the radar sensor
area or camera area of
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, in-
cluding 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 ra-
dar 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 system cannot detect and re-
act in time (for example, pedes-
trian moving quickly toward the
vehicle at close range, vehicle cut-
ting in, changing lanes, making a
turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is
offset 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).
5-98Starting and driving

–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 af-
ter starting the engine.
– If the vehicle ahead has a unique
or unusual shape, extremely low
or high clearance heights, or un-
usual cargo loading or is narrow
(for example, a motorcycle).
– When the vehicle or pedestrian is
located near a traffic sign, a reflec-
tive 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.
• The system performance may be de-
graded 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’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect 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 AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
• The AEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of ve-
hicles or pedestrians, or if they are
the same size and position as a ve-
hicle or motorcycle’s tail lights. •
The system may keep operating
when the vehicle ahead is turning
right or lef t.
• 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 on-
coming vehicle in front of your
vehicle.

system may react to:
– objects on the roadside (traffic sign, guardrail, pedestrian, motor-
cycle, vehicle, etc.)
– pedestrians when driving on the narrow alleys, etc. – pedestrians who temporarily pro-
trude into or approaching the
driving lane to avoid the obstacles
on the road shoulder
– objects above road (low bridge, traffic sign, etc.)
– objects on the road surface (rail- road track, grate, steel plate, etc.)
– objects in the e parking garage (beam, pillar, etc.)
– pedestrians or motorcycles ap- proaching the travelling lane
– vehicles, pedestrians, motor- cycles or objects in adjacent lanes
or close to the vehicle – oncoming pedestrians
– objects on the road (such as trees)
• Braking distances increase on slip-
pery surfaces.
• Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
