■Daytime running light system (veh icles with halogen headlights)
● To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the hybrid system
is started and the parking brake is released with the headlight switch off or in
the “AUTO” position. (Illuminate dimmer than the headlight high beam.)
Daytime running lights are not designed for use at night.
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 economy.
■ Headlight control sensor
■ Automatic light off system
●When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after the power switch is turned off and a door is opened and all of the
doors and trunk are closed. (The lights turn off immediately if on the
key is pressed twice after all the doors are closed.)
● When only the tail lights are on: The tail lights turn off automatically if the
power switch is turned off and the driver’s door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn th\
e light
switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.
■ Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCES-
SORY mode and the driver’s door is opened while the lights are turned on. 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.

1884-3. Operating the lights and wipers
■Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the n\
umber
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
■ Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 461)
NOTICE
■To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is
off.

The Automatic High Beam indica-
tor will come on when the head-
lights are turned on automatically
to indicate that the system is
active.
Automatic High Beam∗
∗: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetlights, the lights of vehicles
ahead etc., and automatically turns the high beam on or off as
necessary.
WARNING
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning the high beam on or off manually if
necessary.

matically turned on (after approximately 1 second):
• Vehicle speed is above approximately 25 mph (40 km/h).
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
● If any of the following conditions are fulfilled, the high beam will be automat-
ically turned off:
• Vehicle speed drops below approximately 19 mph (30 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■ Camera sensor detection information
●The high beam may not be automatically turned off in the following situa-
tions:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
● The high beam may be turned off if a vehicle ahead that is using fog lights
without using the headlights is detected.
● House lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beam to switch to the low beams, or the low beams to
remain on.
● The following factors may affect the amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of vehicles ahe\
ad
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface
etc.)
• The number of passengers and amount of luggage
● The high beam may be turned on or off when the driver does not expect it.
● Bicycles or similar objects may not be detected.

1924-3. Operating the lights and wipers
●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low beams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or ca mera sensor is deformed or dirty.

• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or have are not aimed properly.
• When driving through an area of in termittently changing brightness and
darkness.
• 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.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.
■ If the Automatic High Beam indicator flashes

1964-3. Operating the lights and wipers
■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle
is stationary.
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode while the power switch is in ON mode,
the wipers will operate once to show that AUTO mode is activated.
● If the temperature of the raindrop sensor is 194°F (90°C) or higher, or
14°F (-10°C) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir. ●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
WARNING
■Caution regarding the use of windsh ield wipers in AUTO mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers or anything else do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
