5-3. Operating the lights and wipers
■Daytime running light system
●The daytime running lights illuminate using the same lights as the head-
lights, and illuminate dimmer than the headlights.
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designed for use at
night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the , , or
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the park-
ing 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 economy.
■Headlight control sensor (if equipped)
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.
Air conditioning operation may also be
interrupted.

●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 front camera is deformed or dirty.
• The front camera temperature is extremely high.
• 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 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.

■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the position while the power switch is in
ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
●If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
●If the temperature of the raindrop sensor is 185F (85C) or higher, or 5F
(-15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
washer fluid tank.
■Customization
Settings of AUTO mode operation can be changed.
(Customizable features: P. 753) ●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.
