AEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The AEB system cannot detect all ve-hicles under all conditions.
∙ The radar sensor does not detect the following objects:
– Pedestrians, animals or obstacles in the roadway.
– Oncoming vehicles.
– Crossing vehicles.
∙ The radar sensor has some perfor- mance limitations. If a stationary ve-
hicle is in the vehicles’s path, the AEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h). ∙ The radar sensor may not detect a
vehicle ahead in the following
conditions:
– Dirt, ice, snow or other material covering the radar sensor.
– Interference by other radar sources.
– Snow or road spray from traveling vehicles.
– If the vehicle ahead is narrow (e.g. motorcycle).
– When driving on a steep downhill slope or roads with sharp curves.
∙ In some road or traffic conditions, the AEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
∙ Braking distances increase on slip- pery surfaces. ∙ The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
structions of the sensor area such as
ice, snow, stickers, etc. In these cases,
the system may not be able to worn
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.

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
AEB system is automatically turned off.
The AEB system warning light (orange) will
illuminate.
Action to take:
When the above conditions no longer exist,
the AEB system will resume automatically.
Condition B
When the radar sensor of the front bumper
is covered with dirt or is obstructed, the
AEB system will automatically be canceled.

could result in serious injury or death.
∙T
he AEB with Pedestrian Detection sys-
tem is a supplemental aid to the driver.
It is not a replacement for the driver’s
attention to traffic conditions or re-
sponsibility to drive safely. It cannot
prevent accidents due to carelessness
or dangerous driving techniques.
∙The AEB with Pedestrian Detection sys-
tem does not function in all driving,
traffic, weather and road conditions.
The AEB with Pedestrian Detection system
can assist the driver when there is a risk of
a forward collision with the vehicle ahead in
the traveling lane or with a pedestrian
ahead in the traveling lane. The AEB with Pedestrian Detection system
uses a radar sensor located on the front of
the vehicleBto measure the distance
to the vehicle ahead in the same lane.

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 following
objects: – Small pedestrians (including small
children), animals and cyclists.
– Pedestrians in wheelchairs or us- ing mobile transport such as
scooters, child-operated toys, or
skateboards.
– Pedestrians who are seated or oth- erwise not in a full upright stand-
ing or walking position.
– Oncoming vehicles
– Crossing vehicles
– Obstacles on the roadside
∙ The AEB with Pedestrian Detection system has some performance
limitations.
– If a stationary vehicle is in the vehi- cle’s path, the AEB with Pedestrian
Detection system will not function
when the vehicle is driven at
speeds over approximately
50 mph (80 km/h). – For pedestrian detection, the AEB
with Pedestrian Detection system
will not function when the vehicle
is driven at speeds over approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10 km/h).
∙ The AEB with Pedestrian Detection system will not function for pedestri-
ans in darkness or in tunnels, even if
there is street lighting in the area.
∙ The AEB with Pedestrian Detection system may not function if the vehicle
ahead is narrow (for example, a
motorcycle).
∙ The AEB with Pedestrian Detection system may not function if the speed
difference between the two vehicles is
too small.

properly or detect a vehicle ahead in
the following conditions:
– Poor visibility (conditions such as rain, snow, fog, dust storms, sand-
storms, and road spray from other
vehicles)
Starting and driving5-143

– Driving on a steep downhill slopeor 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 the windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
– Strong light (for example, sunlight or high beams from oncoming ve-
hicles) enters the front camera.
Strong light causes the area
around the pedestrian to be cast in
a shadow, making it difficult to see.
– A sudden change in brightness oc- curs. (For example, when the ve-
hicle 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 partially
obscured or unidentifiable due to
the pedestrian transporting lug-
gage, wearing bulky or very loose-
fitting clothing or accessories.
∙ 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 trunk
room 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 blockage of sensor areas covered
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 AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is nec-
essary, depress the accelerator pedal
to override the system.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.
