PRIUS PHV_OM_OM47C99E_(EE)
This system allows the headlights and front position lights to be turned
on for 30 seconds when the power switch is off.
Pull the lever toward you and
release it with the light switch is in
after turning the power
switch off.
Pull the lever toward you and
release it again to turn off the
lights.
■ Daytime running light system
To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the hybrid system is
started and the parking brake is released with the headlight switch in the
position. Daytime running lights are not designed for use at night.
■ Headlight control sensor
Follow me home system
IO53PH031
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be interrupted.

3845-5. Using the driving support systems
PRIUS PHV_OM_OM47C99E_(EE)
The pre-crash safety system is equipped with a sophisticated com-
puter that will record certain data, such as:
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-crash safety system functions
• Information (such as the distance and relative speed between your
vehicle and the vehicle ahead or other objects)
The pre-crash safety system does not record conversations, sounds
or pictures.
●Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific
vehicle or vehicle owner

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-crash safety system uses a radar sensor and camera
sensor to detect vehicles and pedestrians in front of your vehi-
cle. When the system determines that the possibility of a frontal
collision with a vehicle or pedestrian is high, a warning operates
to urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (P. 399)

3965-5. Using the driving support systems
PRIUS PHV_OM_OM47C99E_(EE)
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.
◆Pre-crash braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.

WARNING
■Limitations of the pre-crash safety system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-crash safety system instead of normal braking opera-
tions under any circumstances. This system will not prevent collisions or
lessen collision damage or injury in every situation. Do not overly rely on
this system. Failure to do so may lead to an accident, resulting in death or
serious injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 401
• Conditions under which the system may not operate properly: P. 4 0 3
● Do not attempt to test the operation of the pre-crash safety system your-
self, as the system may not operate properly, possibly leading to an acci-
dent.
■ Pre-crash braking
● When the pre-crash braking function is operating, a large amount of brak-
ing force will be applied.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the pre-crash braking function operation will be canceled after approxi-
mately 2 seconds. Depress the brake pedal as necessary.
● The pre-crash braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is bei ng turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-crash
braking function from operating.
● In some situations, while the pre-crash braking function is operating, oper-
ation of the function may be canceled if the accelerator pedal is depressed
strongly or the steering wheel is turned and the system determines that
the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-crash braking function.

PRIUS PHV_OM_OM47C99E_(EE)
■Operational conditions
The pre-crash safety system is enabled and the system determines that the
possibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
●Pre-crash warning:
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
●Pre-crash brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (20 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 30 and 80 km/h [20 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 30 km/h (20 mph) or more.
●Pre-crash braking:
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
●If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time
●If the shift position is in R
●If VSC is disabled (only the pre-crash warning function will be operational)
■Pedestrian detection function
■Cancelation of the pre-crash braking
If either of the following occur while the pre-crash braking function is operat-
ing, it will be canceled:
●The accelerator pedal is depressed strongly.
●The steering wheel is turned sharply or abruptly. The pre-crash safety system detects
pedestrians based on the size, profile,
and motion of a detected object. However,
a pedestrian may not be detected
depending on the surrounding brightness
and the motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 405)
