NOTICE
●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
temporarily stop operating. If the EyeSight system repeatedly stops
operating several times, contact
any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer and have the sys-
tem inspected.
• The stereo camera lenses are smeared such as from fingerprints.
• The stereo camera has become misaligned due to a strong impact.
●When there is a malfunction in the EyeSight system, turn off Pre-Colli-
sion Braking System (P.183) and
Lane Departure Warning (P.215), and stop using Adaptive
Cruise Control and Conventional
Cruise Control. Contact any author- ized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer and have the system inspected.
●When the slip indicator is illumi-nated, Pre-Collision Braking Sys-
tem may not operate properly. If the
slip indicator is illuminated, turn off Pre-Collision Braking System. Also,
do not use Adaptive Cruise Control
or Conventional Cruise Control.
Handling of the stereo cam-
era
NOTICE
●The stereo camera monitors and
detects smears or blurs on the front of the camera. However, detection
is not 100% accurate.
Under certain conditions, the func-
tion may fail to detect smears or blurs on the front of the stereo cam-
era accurately. In addition, this
function may not detect that there is snow or ice on the windshield close
to the stereo came ra. In such condi-
tions, be sure to keep the wind- shield clean at all times (indicated
by ). Otherwise the system may
not operate correctly. When this function detects that the front of the
stereo camera is smeared or
blurred, no EyeSight functions can be activated except for Conven-
tional Cruise Control.

●When the difference in speed with
the obstacle in front is the following
figure*1or more, it may not be possi- ble to avoid a collision. Even if the
speed difference is the following fig-
ure*1 or less, in cases such as when another vehicle cuts in front
of you, or in other cases depending
on visibility, the condition of road
surface and other factors*2, the function may be unable to stop the
vehicle or may not activate.
Pre-Collision Braking Assist also may not activate depending on the
conditions*2 listed below.
*1: For vehicles: approximately 50
km/h (30 mph),
For pedestrians: approximately 35
km/h (20 mph)
*2: Conditions in which Pre-Collision
Braking System cannot detect
obstacles:
• Distance to obstacle in front of you,
speed difference, proximity condi- tions, lateral di splacement (the
amount of offset)
• Vehicle conditions (amount of load,
number of occupants, etc.)
• Road conditions (grade, slipperi-
ness, shape, bumps, etc.)
• Visibility ahead is poor (rain, snow,
fog or smoke, etc.)
• The detected object is something
other than a vehi cle, motorcycle,
bicycle or pedestrian.
A domestic animal or other animal
(a dog or deer, etc.)
A guardrail, telephone pole, tree,
fence or wall, etc.
• Even if the obstacle is a motorcycle, bicycle or pedestrian, depending on
the brightness of the surroundings
as well as the relative movement, and aspect or angle of the object,
there may be cases when the sys-
tem cannot detect it.
• The system determines that opera-
tion by the driver (based on acceler- ator pedal operation, braking,
steering wheel angle, etc.) is
intended as evasive action.
• Vehicle maintenance status (brake
systems, tire wear, tire pressure, etc.)
• A trailer or another vehicle, etc. is being towed.
• The brakes are cold due to the out- side temperature being low or just
after starting the engine.
• The brakes are overheated on
downhill grades (braking perfor-
mance is reduced).
• In rain or after washing the vehicle
(the brakes are wet and braking performance is reduced.)
• Recognition conditions of the stereo camera
In particular, the function may be
unable to stop the vehicle or may not
activate in the following cases.
Bad weather (for example heavy
rain, a blizzard or thick fog)
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 or
dust stir up generated by the vehicle
in front or oncoming traffic.

When there is an obstacle in front of you during driving, the system acti-
vates 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 there is a risk of collision, an alert sounds
repeated short beeps and the indicators on the meter display illuminate to warn the
driver.
The Following Distance Warning operates when Adaptive Cruise Control is not acti-
vated.
When the driver depresses the brake pedal to decelerate and achieves a suitable
following distance, the warning is canceled.
First braking and warning:
When the system determines that there is a high risk of collision 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 situa-
tions, engine output may also be controlled. If the system determines that the
amount of evasive action (braking, steering, etc.) taken by the driver has reduced
the risk of collision, braking activation is canceled.
Secondary braking and warning:
If the system then determines that the risk of collision is extremely high, the alert

changes to a continuous beeping sound and stronger braking control is activated.
Despite any evasive action ta ken by the driver, if the system subsequently deter-
mines that a collision is unavoidable, braking and engine output are controlled by
the system.
When the vehicle is comple tely 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 start creeping. To stop the vehicle com-
pletely, depress the brake pedal after the vehicle has stopped.
●Neither first braking nor secondary brak ing will operate in the following cases.
• The vehicle speed is approximately 1 km/h (1 mph) or less (When the shift lever is in the N position and your vehicle speed is approximately 4 km/h (2 mph) or less)
or 200 km/h (125 mph) or more.
• VSC is active.
●If the system detects th e 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 longer period of time.
One of the reasons for this is due to a large speed difference with an obstacle in front. In those cases, stronger or weaker braking control may be activated.
After the Pre-Collision Braking System operation, a message appears and
stays on the meter display for a certain period of time.

Adaptive Cruise Control is designed for use on expressways, freeways,
toll roads, motorways and similar lim-
ited access roads. It is not intended to be used in city traffic. In the following
conditions, do not use Adaptive
Cruise Control. Doin g so may result in an accident.
●Ordinary roads (roads other than those mentioned above)
• Depending on the driving environ-
ment (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 accident.
●Sharp curves or winding roads
●Frozen roads, snow-covered roads
or other slippery road surfaces
• The tires may spin, causing loss of
control of the vehicle.
●Traffic conditions when frequent
acceleration and deceleration make
