not designed for use at night.)
• The fuel cell system is operating
• The parking brake is released
• The headlight switch is in the

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

■12-volt battery-saving function
In order to prevent the 12-volt bat-
tery of the vehicle from discharging, 
if the headlights and/or tail lights are 
on when the power switch is turned

vehicles ahead, street-
lights, etc., and automati-
cally turns the high beams 
on or off as necessary.
WARNING

■Conditions to t urn the high 
beams on/off automatically
●When all of the following condi-
tions are met, the high beams will 
be turned on automatically (after

mately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is  dark.
• There are no vehicles ahead with  headlights or tail lights turned on.

approximately 17  mph (27 km/h).
• The area ahead of the vehicle is  not dark.
• Vehicles ahead have their head- lights or tail lights turned on.
• There are many streetlights on the 
road ahead.
■Front camera detection infor-
mation
●The high beams may not be auto-
matically turned off in the following 
situations:
• When a vehicle suddenly appears  from around a curve
• When the vehicle is cut in front of  by another vehicle
• When vehicles ahead cannot be  detected due to repeated curves, 
road dividers or roadside trees
• When vehicles ahead appear in a  faraway lane on a wide road
• When the lights of vehicles ahead 
are not on
●The high beams may be turned off 
if a vehicle ahead that is using fog 
lights without its headlights turned 
on is detected.
●House lights, street lights, traffic 
signals, and illuminated billboards 
or signs and other reflective 
objects may cause the high 
beams to change to the low 
beams, or the low beams to 
remain on.
●The following fact ors may affect 
the amount of time taken for the 
high beams to turn on or off:
• The brightness of the headlights,  fog lights, and ta il lights of vehi-
cles ahead
• The movement and direction of  vehicles ahead
• When a vehicle  ahead only has 
operational lights on one side
• When a vehicle ahead is a two- wheeled vehicle
• The condition of the road (gradi- ent, curve, condition of the road 
surface, etc.)
• The number of passengers and  amount of luggage in the vehicle
●The high beams may turn on or off 
unexpectedly.
●Bicycles or similar vehicles may 
not be detected.
●In the following situations the sys-
tem may not be able to correctly 
detect the surrounding brightness 
level. This may cause the low 
beams to remain  on or the high 
beams to flash or dazzle pedestri-
ans or vehicles ahead. In such a 
case, it is necessary to manually 
switch between the high and low 
beams.

■Effects of vehicle speed on 
wiper operation (vehicles with 
rain-sensing windshield wipers)

AUTO mode, vehicle speed affects 
the time until the drip prevention 
wiper sweep occurs.
With low speed windshield wiper 
operation selected, wiper operation 
will be switched fro m low speed to 
intermittent wiper operation only 
when the vehicle is stationary.
(However, when the sensor sensitiv-
ity is adjusted to the highest level, 
the mode cannot be switched.)
■Raindrop sensor (vehicles with 
rain-sensing windshield wipers)
●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 b ugs, etc., are 
present on the windshield.
●If the wiper is turned to AUTO 
mode while the power switch is in 
ON, the wipers will operate once 
to show that AUTO mode is acti-
vated.
●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.

■Front door opening linked wind-
shield wiper stop function 
(vehicles with  rain-sensing 
windshield wipers)
When   is selected and the wind-
shield wipers are operating, if a front 
door is opened while the vehicle is 
stopped and the P shift position is 
selected, operation of the wind-
shield wipers will be stopped to pre-
vent anyone near the vehicle from 
being sprayed by water from the

Take care that your fingers or any-
thing else do not become caught 
in the windshield wipers.
■Caution regarding the use of 
washer fluid

washer fluid unt il 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
