(driving side of the road) does not
match the traffic lane, full Eye-
Sight performance may not be
available.
*: Characteristics and settings that are affected by specific differ-
ences between right-hand drive
and left-hand drive vehicles
cannot be changed.
●The system may not operate
correctly under the conditions
listed below. When these condi-
tions occur, turn off Pre-Colli-
sion Braking Sy stem. Also, do
not use Adaptive Cruise Control
or Conventional Cruise Control.

NOTICE
●The characteristics of the stereo
camera are simila r to those of
human eyes. For this reason,
conditions that make it difficult
for the driver to see in the for-
ward direction have the same
effect on the stereo camera.
They also make it difficult for the
system to detect vehicles,
obstacles, and traffic lanes.
●Detection by the EyeSight sys-
tem is limited to objects that are
within the range of the stereo
camera’s field of view. Also,
after an object enters the range
of the camera’s field of view, it
may take some time for the sys-
tem to detect it as a controllable
target and to warn the driver.
Low objects surrounding the
vehicle cannot be detected.

WARNING
 The speed difference between
your vehicle and an obstacle is 4
mph (5 km/h) or less (As braking
is performed once the obstacle is
in close proximity to your vehicle,
depending on the shape and size
of the obstacle, there may be
some cases when the obstacle is
outside the range of the camera’s
field of view.).
 On sharp curves, steep uphill
grades or steep downhill grades
 On a bumpy or unpaved road
 There are changes in bright-
ness, such as at a tunnel
entrance or exit.

When there is an obstacle in front of you during driving, the system
activates in the following sequence in order to warn the driver and to
activate braking control and the stop lights.
Following distance warning:
When the system determines that t here is a risk of collision, an alert sounds
repeated short beeps and the indicators on the meter display il luminate to
warn the driver.
The Following Distance Warning ope rates when Adaptive Cruise Control is
not activated.
When the driver depresses the bra ke pedal to decelerate and achieves a
suitable following distanc e, the warning is canceled.
First braking and warning:
When the system determines that there is a high risk of collisi on with an
obstacle in front, an alert sounds repeated short beeps and the indicators
on the meter display illuminate to warn the driver. Braking control may be
activated and in some situations, engine output may also be controlled. If
the system determines that the amount of evasive action (brakin g, steering,
etc.) taken by the driver has reduced the risk of collision, br aking activation
is canceled.
Secondary braking and warning:
WARNING
The EyeSight system’s Pre-Colli-
sion Braking function also identi-
fies pedestrians as obstacles.
However, depending on the con-
ditions, there may be cases when
the system cannot detect a
pedestrian. In the following condi-
tions, the possibility that the sys-
tem may not be able to detect a
pedestrian as an object is particu-
larly high.
●Pedestrians are walking in a
group.
●A pedestrian is next to a wall or
other obstacle.
●A pedestrian is using an
umbrella.
●A pedestrian is wearing clothes
that are a similar color to the
surrounding environment.
●A pedestrian is carrying bulky
luggage.
●A pedestrian is bent over,
crouching down o r lying down.
●A pedestrian is in a dark loca-
tion.
●A pedestrian suddenly crosses
in front of you from the side or
suddenly runs in front of you.
