Operating the switch turns
on the lights as follows:U.S.A.
Canada
1 The side marker, parking,
tail, license plate, instrument
panel lights, daytime running
lights ( P.248) turn on.
2 The headlights and all
lights listed above (except
daytime running lights) turn
on.
3 The headlights, daytime
running lights ( P.248) and all the lights listed above turn
on and off automatically.
4 Off (for the U.S.A. only)
■AUTO mode can be used when
The power switch is in ON.
■Daytime running light system
●The daytime runn ing lights illumi-
nate using the same lights as the
parking lights and illuminate but at
a higher intensity. (On some mod-
els: Using the same lights as the
headlights but at a lower intensity.)
●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 EV system is operating
• The parking brake is released
• The headlight switch is in the
or position
• The surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers greater durability
and consumes less electricity, so
it can help improve electricity con-
sumption.
■Headlight control sensor
The sensor may not function prop-
erly if an object is placed on the sen-
sor, 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 t he automatic head-
light system to malfunction.
Headlight switch
The headlights can be oper-
ated manually or automati-
cally.

system
The level of the headlights is auto-
matically adjusted according to the
number of passengers and the load-
ing condition of the vehicle to
ensure that the headlights do not
interfere with other road users.
■Windshield wiper linked head-
light illumination
When driving during daytime with
the headlight switch turned to , if the windshield wipers are used, the
headlights will turn o
n automatically
after several seconds to help

on when the power switch is turned
to OFF, the battery saving function
will operate and au tomatically turn
off all the lights af ter approximately
20 minutes.
When any of the following are per-
formed, the 12-volt battery-saving
function is canceled once and then
reactivated. All the lights will turn off

●The headlights may change to the
low beams if a vehicle ahead that
is using fog lights without its head-
lights turned on is detected.
●House lights, street lights, traffic
signals, and illuminated billboards
or signs may cause the high
beams to change to the low
beams, or the low beams to
remain on.
●The following may change the tim-
ing at which the headlights
change to the low beams:

may not be detected.
●In the following situations, the sys-
tem may not be able to correctly

2525-3. Operating the lights and wipers
Owners Manual_USA_M42C01_endetect the brightness of the sur-
roundings. This may cause the
low beams to remain on or the
high beams to flash or dazzle
pedestrians or vehicles ahead. In
such a case, it is necessary to
manually change between the
high beams and low beams.
• When there are lights similar to
headlights or tail li ghts in the sur-
rounding area
• When headlights or tail lights of
vehicles ahead are turned off,
dirty, changing color, or not aimed
properly
• When the headlights are repeat- edly changing between the high
beams and low beams.
• When use of the high beams is inappropriate or when the high
beams may be flashing or daz-
zling pedestrians or other drivers.
• When the vehicle is used in an area in which vehicles travel on
the opposite side of the road of
the country for wh ich the vehicle
was designed, for example using
a vehicle designed for right-hand
traffic in a left-hand traffic area, or
vice versa
• When it is necessary to disable the system:  P. 2 5 9
• Situations in which the sensors
may not operate properly: P. 2 6 3

■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops. An optical
sensor is adopt ed. It may not
operate properly when sunlight
from the rising or setting of the
sun intermittently strikes the wind-
shield, or if bugs, etc., are present
on the windshield.
●If the wiper switch i s turned to the
“AUTO” position while the power
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●If the wiper sensitivity is adjusted

2565-3. Operating the lights and wipers
Owners Manual_USA_M42C01_ento higher, the wip
er may operate
once to indicate the change of
sensitivity.
●If the temperature of the raindrop
sensor is 194°F (90°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
v oi r.
WARNING
■Caution regarding the use of
windshield wipers in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that your fingers or any-
thing else does 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.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the EV sys-
tem is off.
