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.

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)
• Images from the camera sensor (available only when the pre-crash
braking function is operating)
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
*1 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
*2 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. 372)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional for
details.
*2: Depending on the region in which the vehicle was sold, the pre-crash
braking function (automatic braking function) may not be available. Con-
tact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for details.

3805-5. Using the driving support systems
PRIUS PHV_OM_OM47A89E_(EE)●In some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
●Some pedestrians such as the following may not be detected by the radar
sensor and camera sensor, preventing the system from operating prop-
erly
*4:
• Pedestrians shorter than approximately 1 m (3.2 ft.) or taller than approx-
imately 2 m (6.5 ft.)
• Pedestrians wearing oversized clothing (a rain coat, long skirt, etc.), mak-
ing their silhouette obscure
• Pedestrians who are carrying large baggage, holding an umbrella, etc.,
hiding part of their body
• Pedestrians who are bending forward or squatting
• Pedestrians who are pushing a stroller, wheelchair, bicycle or other vehi-
cle
• Groups of pedestrians which are close together
• Pedestrians who are wearing white and look extremely bright
• Pedestrians in the dark, such as at night or while in a tunnel
• Pedestrians whose clothing appears to be nearly the same color or
brightness as their surroundings
• Pedestrians near walls, fences, guardrails, or large objects
• Pedestrians who are on a metal object (manhole cover, steel plate, etc.)
on the road
• Pedestrians who are walking fast
• Pedestrians who are changing speed abruptly
• Pedestrians running out from behind a vehicle or a large object
• Pedestrians who are extremely close to the side of the vehicle (outside
rear view mirror, etc.)
*4: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available.

■If the PCS warning light flashes and a warning message is displayed on
the multi-information display
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
●In the following situations, the warning light will turn off, the message will
disappear and the system will become operational when normal operating
conditions return:
• When the radar sensor or camera sensor or the area around either sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around either sen-
sor is cold, such as in an extremely cold environment
• When the radar sensor or front grille emblem is dirty or covered with
snow, etc.
• When the part of the windshield in front of the camera sensor is fogged
up or covered with condensation or ice
(Defogging the windshield: P. 509)
• If the camera sensor is obstructed, such as when the hood is open or a
sticker is attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not
disappear, the system may be malfunctioning. Have the vehicle inspected
by any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately.
■If VSC is disabled
●If VSC is disabled (P. 493), the pre-crash brake assist and pre-crash brak-
ing functions are also disabled.
●The PCS warning light will turn on and “VSC Turned Off Pre-crash Brake
System Unavailable” will be displayed on the multi-information display.

■Dynamic radar cruise control with full-speed range can be set when
●The shift position is in D.
●Vehicle speed is above approximately 50 km/h (30 mph).
However, when a preceding vehicle is detected, the dynamic radar cruise
control with full-speed range can be set even if the vehicle speed is at or
below approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
●Actual vehicle speed falls below approximately 40 km/h (25 mph) when
there are no vehicles ahead.
●The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed below approximately 40 km/h (25 mph). Otherwise, the sen-
sor can not properly detect the vehicle.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off by pressing the VSC OFF
switch.
●The sensor cannot detect correctly because it is covered in some way.
●Pre-crash braking is activated.
●Intelligent Clearance Sonar is operated. (if equipped)
●The parking brake is operated.
●The vehicle is stopped by system control on a steep incline.
●The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.
In this situation, the shift position may automatically switch to P. (P. 336)
If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.

PRIUS PHV_OM_OM47A89E_(EE)■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 406) will not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
●Preceding vehicle has an extremely high
ground clearance
