The EyeSight system can also
detect pedestrians. The Eye-
Sight system detects pedestri-
ans from their size, shape and
movement. The system detects
a pedestrian when the contour
of the head and shoulders are
clear.Approx. 3 1/3 ft - 6 2/3 ft (1-2
m)
NOTICE
●The exhaust gas emitted by the
vehicle in front is clearly visible
in cold weather, etc.
●There is an obstacle on a curve
or intersection.
●A vehicle or an object is being
narrowly passed.
●Stopping very close to a wall or
a vehicle in front
●Passing through water spray
from road sprinklers or snow
clearing sprinklers on the road
If there are installed accessories,
etc. that are pro truding beyond
the edge of the front bumper, the
vehicle’s length will increase and
the system may not be able to
prevent a collision.
If the driver oper ates the brake
pedal during automatic braking,
the pedal may feel stiff; however,
this is normal. By depressing the
brake pedal further you can apply
more braking force.

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.

If the system then determines that the risk of collision is ext remely high, the
alert changes to a continuous beeping sound and stronger brakin g control
is activated. Despite any evasive action taken by the driver, if the system
subsequently determine s that a collision is unavoidable, brakin g and
engine output are con trolled by the system.
When the vehicle is completely stopped by the automatic braking system, a
short tone “3 intermittent beeps , 1 short beep and 1 long beep” will sound
and braking will be gradually released and the vehicle will sta rt creeping. To
stop the vehicle completely, d epress the brake pedal after the vehicle has
stopped.
●Neither first braking nor secondary braki ng will operate in the following
cases.
• The vehicle speed is approximately 1 mph (1 km/h) or less (Whe n the shift
lever is in the N position and your vehicle speed is approximat ely 2 mph (4
km/h) or less) or 100 mph (160 km/h) or more.
• VSC is active.
●If the system detects the stop lights of the vehicle in front, your vehicle will
start decelerating earlier than if it does not.
●There are some cases where the first braking is applied for a l onger period
of time. One of the reasons for t his is due to a large speed difference with
an obstacle in front. In those cases, stronger or weaker brakin g control
may be activated.
After the Pre-Collision Braki ng System operation, a message
appears and stays on the meter display for a certain period of time.

System is activated (when the

*: If equipped
Adaptive Cruise Con-
trol*
Adaptive Cruise Control is a
driving support system
intended to allow more com-
fortable driving on express-
ways, freeways and
interstate highways. The
stereo camera detects vehi-
cles in front that are driving
in the same traffic lane, and
your vehicle follows the
vehicle in front (up to the
maximum speed of the set
vehicle speed). While fol-
lowing, your vehicle will
automatically maintain a fol-
lowing distance that corre-
sponds to the speed of the
vehicle in front. The vehicle
is capable of being con-
trolled at a speed between 0
mph (0 km/h) and approxi-
mately 90 mph (145 km/h).
Please remember that you
should not exceed posted
speed limits.
WARNING
●This system does not provide
the driver with an automatic
driving function that handles all
traffic conditions.
●Do not rely excessively on
Adaptive Cruise Control. This
system is not intended to assist
in driving when the driver is not
paying full attention to what is
ahead of him/her due to distrac-
tions or a lack of concentration
while driving, or under condi-
tions of poor visibility. It is not
intended to prevent rear-end
collisions.
Strive for safe driving at all
times. Always maintain a safe
following distance behind the
vehicle in front of you, pay
attention to your surroundings
and the driving conditions, and
operate the brake pedal and
take other actions as necessary.
●When using Adaptive Cruise
Control, always set the speed
according to the speed limit,
traffic flow, road conditions, and
other conditions.
●Before using t he system, per-
form a daily inspection and ver-
ify that there are no
malfunctions of the tires or
brakes.
Refer to the separate “Owner’s
Warranty Informat ion Booklet” or
“Owner’s Manual Supple-
ment/Scheduled Maintenance
Guide”.
●When you do not want to use
Adaptive Cruise Control, be
sure to turn it off by pressing the
“ON-OFF” switch. If the switch
is left on, cruise control may be
accidentally engaged, possibly
resulting in an accident.
●Before using Adaptive Cruise
Control, be sure to fully verify
the safety of the vehicle occu-
pants and the area around the
vehicle. Never operate the
cruise control from outside the
vehicle.

: The wheels and tires have functions that are critically
important. Be sure to use the
correct ones. (
P.386)
*2: If the brake s ystem warning
light (red) does not turn off,
immediately pull the vehicle
over in a safe place and con-

Adaptive Cruise Control is
designed for use on expressways,
freeways, toll roads, interstate
highways and similar limited
access roads. It is not intended to
be used in city traffic. In the fol-
lowing conditions, do not use
Adaptive Cruise Control. Doing so
may result in an accident.
●Ordinary roads (roads other
than those mentioned above)
• Depending on the driving envi- ronment (complexity of roads
and other factors), the system
may not be able to perform as
the traffic conditions require,
and that may result in an acci-
dent.
●Sharp curves or winding roads
Page 192 of 449

1924-5. EyeSight
WARNING
●Frozen roads, snow-covered
roads or other slippery road sur-
faces
• The tires may spin, causing loss of control of the vehicle.
●Traffic conditions when fre-
quent acceleration and deceler-
ation make it difficult to maintain
the following distance
• It may not be po ssible for the
system to perform as the traffic
conditions require.
●Steep downhill grades
• The set vehicle speed may be exceeded.
●On a steep continuous downhill
grade
• The brakes may overheat.
●Roads and overpasses with
repeated steep uphill and down-
hill grades
• Detection of the vehicle in front may be lost, or the road surface
may be detected instead of the
vehicle in front, making correct
control impossible.
●Entering a sharp curve/turn into
an interchange or junction, or a
service area, parking area, toll
booth or other facilities
• Detection of the vehicle in front may not be possible.
●There are changes in bright-
ness, such as at a tunnel
entrance or exit.
●Visibility is poor due to sand,
smoke or water vapor blowing in
the wind, or the front vision is
obscured due to water
splashes, snow, dirt, water
spray from road sprinklers or
snow clearing sprinklers on the
road, or dust stir up generated
by the vehicle in front or oncom-
ing traffic.
• Detection of the vehicle in front may be lost, or water or other
substances may be incorrectly
detected instead, making cor-
rect control impossible.
●In adverse weather, such as
heavy snow or snowstorms
