NOTICE
●Under the conditions listed
below, it will become more diffi-
cult for the system to detect the
vehicle in front, motorcycles,
bicycles, pedestrians and obsta-
cles on the road, and lane mark-
ers. Also, EyeSight may
temporarily stop operating.
However, the temporary stop
will be canceled once these
conditions have improved and
the vehicle is driven for a short
period of time.
• Bad weather (for example heavy rain, a blizzard or thick
fog). In particular, the system is
more likely to temporarily stop
operating when there is an oil
film adhering to the windshield,
a glass coating has been
applied, or poorly performing
wipers are used.
• Strong light is coming from the front (sunlight or headlight
beams of oncoming traffic, etc.).
• The windshield washer is in use.
• Raindrops, water drops, or dirt on the windshield are not wiped
off sufficiently.
• The windshield has become fogged, scratched or smeared,
or snow, dirt ,dust or frost has
adhered to it, or it is otherwise
affected. These will reduce the
stereo camera’s field of view.
Also, light is reflecting off the
dirt, etc.
• The vehicle is tilted at an extreme angle due to loaded
cargo or other factors.
• Visibility is poo r due to sand,
smoke or water vapor blowing in
the wind, or the front vision is
obscured due to water
splashes, snow, dirt or dust stir
up generated by the vehicle in
front or oncoming traffic.
• The stereo came ra’s field of
view is obstructed.
• Through the entra nce or exit of
a tunnel
• The rear aspect of the vehicle in front is low, small or irregular
(for example a low bed trailer,
etc.).
• The obstacle is a fence, a wall or a shutter, etc. with a uniform
pattern (a striped pattern, brick,
etc.) or with no pattern in front.
• The obstacle is a wall or door made of glass or a mirror in
front.
• Driving at night or in a tunnel when there is a ve hicle in front
that does not ha ve its taillights
on
• Driving through a banner or flag, low branches on a tree or
thick/tall vegetation
• On steep uphill or downhill grades
• The stereo camera is obstructed by a hand, etc. (If
even one of the lenses is
obstructed, the system does not
operate properly.)
• It is completel y dark and no
objects are detected.
• The area around the vehicle has a uniform color (such as when
completely covered in snow,
etc.).

• Accurate detecti on is not possi-
ble due to reflections in the
windshield.
●Under the conditions listed
below, EyeSight may temporar-
ily stop operating. If this occurs,
EyeSight will resume operating
when the conditions improve.
• The temperature inside the vehicle is high, such as after the
vehicle was left in bright sun-
shine, or the temperature inside
the vehicle is low, such as after
the vehicle was left in an
extremely cold environment.
• Immediately after the engine starts
●Under the conditions listed
below, it is difficult to recognize
vehicles in front, motorcycles,
pedestrians, obstacles on the
road, traffic lanes, etc. Also, the
EyeSight system may temporar-
ily stop operating. If the Eye-
Sight system repeatedly stops
operating several times, con-
tact a Toyota dealer and have
the system inspected.
• The stereo camera lenses are smeared such as from finger-
prints.
• The stereo camera has become misaligned due to a strong
impact.

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

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.

WARNING
●The windshield has become
fogged, scratched or smeared,
or snow, dirt, dust or frost has
adhered to it, or it is otherwise
affected. These will reduce the
stereo camera’s field of view.
Also, light is reflecting off the
dirt, etc.
●Water droplets from rain or the
window washer, or dirt has not
been fully wiped off the wind-
shield.
• It may not be po ssible to detect
the vehicle in front, making cor-
rect control impossible.
●The stereo camera’s field of
view is obstructed.
The stereo camera may have diffi-
culty detectin g the following
objects or conditions. Operate the
brake pedal and take other
actions as necessary.
●Vehicles at significantly different
speeds (vehicles driving slowly,
stopped or oncoming vehicles,
etc.)
●Vehicles cutting into your lane
●Motorcycles, bicycles, pedestri-
ans and animals, etc.
●Light is poor in the evening or

●At night or in a tunnel when
there is a vehicle in front that
does not have its tail lights on
●Strong light is coming from the
front (sunlight or headlight high
beams, etc.).
●Vehicles in front that have a rear
aspect that is low, small or irreg-
ular (the system may recognize
another part of the vehicle and
will determine operation from
that)
• An empty truck or trailer that has no tailgate or longbed
• Vehicles that have cargo pro- truding from their back ends
• Non-standard shaped vehicles (vehicle transporters or vehi-
cles with a sideca r fitted, etc.)

■Detection of the vehicle in
front by the EyeSight stereo
camera
*
●Under the following road condi-
tions or conditions of your vehi-
cle, detection of the vehicle in
front may not be possible. Vehi-
cles in neighboring traffic lanes
or roadside objects may also be
incorrectly detected. Under con-
ditions such as these, do not
use Adaptive Cruise Control. If
cruise control is currently in use,
operate the brake pedal and
take other actions as necessary.

will drive at that constant speed.
If a vehicle in front is detected while
accelerating to the set vehicle
speed, vehicle following will be
started again.
●When the brakes are applied by
Adaptive Cruise Control, the vehi-
cle’s stop lights will illuminate.
●Even if there is no lead vehicle
present, on a downhill grade, the
Adaptive Cruise Control’s auto-
matic brake may operate in order
to maintain the set vehicle speed.
●Some noises may be audible
during automatic braking. This is
caused by the braking control and
does not indicate a malfunction.
●To temporarily accelerate quickly,
use the accelerator pedal. After
accelerating, the vehicle will grad-
ually return to the set vehicle
speed shown in the set vehicle
speed display.
●If the vehicle in front is no longer
detected while your vehicle is still
controlled by the automatic brak-
ing operation, th e brake will be
automatically released gradually.
Depress the accelerator pedal if
necessary.
●The lead-vehicle following func-
tion has the following characteris-
tics:
• If the lead vehicle’s stop lights are
detected, deceleration will start
earlier than without detection.
• If the vehicle moves to the fast
lane while traveling more than approximately 37 mph (60 km/h),
the system starts acceleration to
the set vehicle speed more quickly
because it is linke
d with the turn
signal.
• If the setting of driving lane is dif-
ferent from the actual driving
direction, the vehicle may start to
accelerate faster than usual when
the driver signals a lane change to
move from the passing lane to the
driving lane. ( P.400)
●Cruise control acceleration char-
acteristics can be set to one of
four levels. ( P.400)
■Increasing the set vehicle
speed
Using the cruise control
switch
Push to the “+ RES” side
briefly.
Every time the switch is pushed,
the set vehicle speed will increase
in increments o f 1 mph (1 km/h)
increment.
Push to the “+ RES” side con-
tinuously.
While the switch is being pushed,
the set vehicle speed will increase
in increments o f 5 mph (5 km/h).
When operating the switch, the
set vehicle speed changes on
the meter display.
NOTICE
If the driver oper ates the brake
pedal during automatic braking,
the pedal may feel stiff; however,
this is not a malfunction. By
depressing the brake pedal fur-
ther you can apply more braking
force. When the brake pedal is
released it will return to its original
condition.
