■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 engine is started and
the parking brake is released. 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
headlight 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 (if equipped)
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 sys-
tem to malfunction.

●
In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestri-
ans to the high beam. Therefore, you should consider turning the high
beam on or off manually rather than relying on the Automatic High Beam
system.
• 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 are not aimed properly.
• When driving through an area of intermittently 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 vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• 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 distress to other drivers or pedestrians nearby.

■The windshield wipers and washer can be operated when
Vehicles without a smart key system:
The engine switch is in the “ON” position.
Vehicles with a smart key system:
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to “AUTO” position while the “ENGINE
START STOP” switch is in IGNITIO N ON mode, the wiper will operate
once to show that “AUTO” mode is activated.
● If the temperature of the raindrop sensor is 185°F (85°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”.
■ 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.
