4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the day-
time running lights turn on automatically whenever the hybrid system is started and
the parking brake is released with the headlight switch in the or “AUTO” posi-
tion. (Illuminate brighter than the parkin g lights.) Daytime running lights are not
designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on th e headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
When the light switch is in or : The headlights and tail lights turn off 30 sec-
onds after the power switch is turned to ACCESSORY mode or turned off and a
door is opened and all of the doors and trun k are closed. (The lights turn off immedi-
ately if on the key is pressed twice after all the doors are closed.)
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .
If any of the doors or trunk lid is kept op en, the lights automatically turn off after 20
minutes.
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading conditio n of the vehicle to ensure that the headlights do not
interfere with other road users. The sensor may not func tion properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
