4-3. Operating the lights and wipers
■Daytime running light system (if equipped)
●Bulb type: The daytime running lights illuminate using the same lights as the
headlights and illuminate dimmer than the headlights.
● LED type: 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 dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (Canada only), or “AUTO”
*
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 ope rating the
headlight switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ 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
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

Driving
●In the situations below, the system may not be able to correctl y detect the
surrounding brightness levels, and may flash or expose nearby p edestrians
to the high beam. Therefore, you should consider turning the hi gh 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 camera 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, d irty, 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 w inding
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 high beam and low beam are repeatedly being switched betwe en in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.
■ Customization
The Automatic High Beam can be turned off.
