the driver through the speakers
inside the instrument panel.
The vehicle’s response to the
driver’s acceleration behavior and
shift operations are also conveyed
in sound.
When Sport mode is selected, the
sound conveyed to the driver will be
louder.

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

position

: When the surroundings are bright

The daytime running lights remain on after

they illuminate, even if the parking brake is

set again.

●

For the U.S.A.: Daytime 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 the 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.

■

curves, road dividers or roadside trees

●

High beam may be turned off if an

oncoming vehicle that is using fog lights

without using the headlights is detected.

●

House lights, street lights, red traffic sig-

nals, and illuminated billboards or signs

may cause the high beam to turn off.

●

The following factors may affect the

amount of time taken to turn high beam

on or off:

• The brightness of headlights, fog lights,

and tail lights of oncoming and preceding

vehicles

• The movement and direction of oncom-

ing and preceding vehicles

• When a oncoming or preceding vehicle

only has operational lights on one side

unexpected by the driver.

●

In the situations below, the system may

not be able to correctly detect the sur-

rounding brightness levels, and may flash

or expose nearby pedestrians to the high

beam. Therefore, you should consider

turning the high beams on or off manually

rather than relying on the Automatic

High Beam system.

lights that are either switched off, dirty,

are changing color, or are not aimed

properly.

• When driving through an area of inter-

mittently changing brightness and dark-

ness.

• When frequently and repeatedly driving

ascending/descending roads, or roads

with rough, bumpy or uneven surfaces

(such as stone-paved roads, gravel

tracks, etc.).

• When frequently and repeatedly taking

curves or driving on a winding road.
