Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed
for use at night.
■ Headlight control sensor (if equipped)
■ Automatic light off system
Opening the driver’s door with the “POWER” switch in ACCESSORY mode
or OFF will turn the headlights and tail lights off.
To turn the lights on again, switch to ON mode, or turn the light switch “OFF”
once and then back to the or position.
■ Automatic headlight leveling system (Vehicle with discharge head-
lights)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
■ If the indicator flashes...
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Customization
Settings (e.g. light sensor sensitivity) can be changed. ( P. 488)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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 con-
trol system to malfunction.

5-1. Essential information
PRIUS_U_(L/O_0802)
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
● Gasoline engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the transmission shift lever
● Whether the driver and front passenger wore seat belts or not
● Driver’s seat position
● SRS airbag deployment data
● SRS airbag system diagnostic data
● Front passenger’s occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performan ce. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is a system to
record data in a crash or a near car crash event. This is called an
Event Data Recorder (EDR).
