Driving
■AUTO mode can be used when
The power switch is in ON mode.
■Daytime running light system
●The daytime running lights illuminate
using the same lights as the parking lights
and illuminate brighter than the parking
lights.
●To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally when all of the following conditions
are met. (The daytime running lights are
not designed for use at night.)
• The hybrid system is started
• The parking brake is released
• The headlight switch is in the (type
B), or “AUTO”
* position

The daytime running lights remain on after
they illuminate, even if the parking brake is
set again.
●For the U.S.A.: Dayt ime running lights
can be turned off by operating the switch.
●Compared to turning on the headlights,
the daytime running light system offers
greater durability and consumes less
electricity, so it can help improve fuel
●If a turn signal light is in use, the daytime
running light, on the same side, is turned
off. For emergency flashers, both are
turned off.
■Headlight control sensor
The sensor may not function properly if an
object is placed on th e sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.
■Automatic light off system
●When the headlights come on: The head-
lights and tail lights turn off 30 seconds
after a door is opened and closed if the
power switch is turned to ACCESSORY
mode or turned off. (The lights turn off
immediately if on the key is
pressed after all the doors are locked.)

equipped)
The level of the headlights is automatically
adjusted according to the number of pas-
sengers and the loadin g condition of the
vehicle to ensure that the headlights do not
interfere with other road users.
■12-volt battery-saving function
In order to prevent the 12-volt battery of the
vehicle from discharging, if the headlights
and/or tail lights are on when the power
switch is turned off the 12-volt battery sav-
ing function will operate and automatically
turn off all the lights after approximately 20
minutes. When the power switch is turned
to ON mode, the 12-volt battery-saving
function will be disabled.

1844-3. Operating the lights and wipers
