■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 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 hybrid system is operating
• The parking brake is released
• The headlight switch is in the (Canada only), , or
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, eve n if the park-
ing brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
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 (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.

■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing win dshield
wipers)
After washing and wiping operation several times, the wipers op erate one
more time after a short delay to prevent dripping. However, thi s function will
not operate while driving.
■ Effects of vehicle speed on wip er operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” 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 o perate once to
indicate the change of sensitivity.
● 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, o perate
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 wash er fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.
(Customizable features: P. 739)
●
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.
