■ 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 engine is started
and the parking brake is released with the headlight switch off or in the
“AUTO” position. (Illuminate brighter than the front position lights.) Daytime
running lights are not designed for use at night.

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.

The pre-crash safety system is equipped with a sophisticated com-
puter that will record certain data, such as:
• How far (if at all) the driver was depressing the accelerator and/or
brake pedal
• 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 another object)
The pre-crash safety system does not record conversations, sounds
or pictures.
● Data usage
Toyota may use the data recorded in these computers 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
The front sensor is located on the
upper side of the windshield. It
consists of 2 types of sensors,
each of which detects information
necessary to operate the drive
assist systems.

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision with a vehicle is high, a
buzzer will sound and the PCS
activation indicator will flash to
urge the driver to take evasive
action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle is high,
pre-crash warning urges the driver to take evasive action and
the potential brake pressure will be increased to help the driver
avoid the collision.
If the system determines that the possibility of a frontal collision
with a vehicle is extremely high, the brakes are automatically
applied to help avoid the collision or help reduce the impact to
the vehicle occupants and the vehicle in the collision.
The pre-crash warning timing can be changed or the system can be
enabled/disabled, as necessary, by operating the switch.

has been parked in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 308, 317)
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash, the system may be malfunction-
ing. Have the vehicle inspected by any authorized Toyota dealer or repairer,
or another duly qualified and equi pped professional immediately.
■ If the TRC and VSC are disabled
