Safety system of your vehicle

In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to “ride” under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
Information
The side and/or curtain air bags may
inflate when the vehicle is rolled over
by a side impact collision, if the vehi-
cle is equipped with side and/or cur-
tain air bags.

Driving your vehicle
•The AEB is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the AEB
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
•In certain instances and
under certain driving condi-
tions, the AEB system may
unintentionally activate. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The AEB system
may not activate and the
warning message will not be
displayed.
(Continued)
(Continued)
•If there is a malfunction with the
AEB system, the autonomous
emergency braking is not
applied even though the brak-
ing system is operating normal-
ly.
•If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
•The AEB system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
•The AEB system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
•The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.

Limitations of the system
The Autonomous Emergency Braking
(AEB) system is designed to monitor
the vehicle ahead or a pedestrian in
the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent, and
if necessary, apply emergency brak-
ing.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the AEB sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
AEB operation may be limited.
Detecting vehicles
The sensor may be limited when:
• The radar sensor or camera is
blocked with a foreign object or
debris
• Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
• There is interference by electro-
magnetic waves
• There is severe irregular reflection
from the radar sensor
• The radar/camera sensor recogni-
tion is limited
• The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.)
• The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
• The driver's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
•The AEB system operates
only to detect vehicles or
pedestrians in front of the
vehicle.
•The AEB system does not
operate when the vehicle is in
reverse.
•The AEB system is not
designed to detect other
objects on the road such as
animals.
•The AEB system does not
detect vehicles in the oppo-
site lane.
•The AEB system does not
detect cross traffic vehicles
that are approaching.
•The AEB system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
WARNING

5-58
Driving your vehicle
• The vehicle in front does not have
their rear lights properly turned ON
• The outside brightness changes
suddenly, for example when enter-
ing or exiting a tunnel
• Light coming from a street light or
an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
• The field of view in front is
obstructed by sun glare
• The windshield glass is fogged up; a
clear view of the road is obstructed
• The vehicle in front is driving errat-
ically
• The vehicle is on unpaved or
uneven rough surfaces, or roads
with sudden gradient changes
• The adverse road conditions cause
excessive vehicle vibrations while
driving
• The vehicle is moving under
ground level or inside a building
• The vehicle is driven near areas
containing metal substances such
as a construction zone, railroad,
etc.• The vehicle in front is moving verti-
cally to the driving direction
• The vehicle in front is stopped ver-
tically
• The vehicle in front is driving
towards your vehicle or reversing
- Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.

5-60
Driving your vehicle
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The AEB system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians
(if equipped)
The sensor may be limited when:
• The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
• The pedestrian is moving very
quickly or appears abruptly in the
camera detection area
• The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
• It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
• There is an item similar to a per-
son’s body structure
• The pedestrian is small
• The pedestrian has impaired
mobility
• The sensor recognition is limited
