Activating the Automatic High
Beam system

1604-3. Operating the lights and wipers
out using the headlights is detected.
●House lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beam to switch to the low
beams, or the low beams to remain on.
●The following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles
ahead
• When a vehicle ahead only has opera- tional lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient,
curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
●The high beam may be turned on or off
when the driver does not expect it.
●Bicycles or similar objects may not be
detected.
●In the situations show n below, the system
may not be able to accurately detect sur-
rounding brightness levels. This may
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• In bad weather (rain, snow, fog, sand-
storms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.

lights.
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of inter-
mittently changing brightness and dark-
ness.

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.

• 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 repeat- edly being switched between in an
abnormal manner.
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby.

■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON
mode.
■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Even when the wipers are not in AUTO
mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.

1644-3. Operating the lights and wipers
With low speed windshield wiper operation
selected, wiper operation will be switched
from low speed to intermittent wiper opera-
tion only when the vehicle is stationary.
(However, when the sensor sensitivity is
adjusted to the highest level, the mode can-
not 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 bugs etc. are
present on the windshield.
●If the wiper is turned to AUTO position
while the engine switch is in IGNITION
ON mode, the wipers will operate once
to show that AUTO mode is activated.
●If the temperature of the raindrop sensor
is 185°F (85°C) or higher, or -22°F (-
30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than AUTO.
■Front door opening linked windshield
wiper stop function (vehicles with rain-
sensing windshield wipers)
When AUTO is selected and the wind-
shield wipers are operatin g, if a front door is
opened while the vehicle is stopped and the
P position is selected, operation of the
windshield wipers w ill be stopped to pre-
vent anyone near the vehicle from being
sprayed by water from the wipers. When
the front door is closed, wiper operation will
resume.
■To protect the windshield wipers
If movement of the windshield wipers is
largely restricted by a foreign object such as snow, the operation of the windshield wip-
ers may be stopped automatically to pro-
tect the windshield wipe
rs. In this case, turn
the windshield wiper switch off and remove
the foreign object, and then use the wind-
shield wipers.
■When stopping the engine in an emer-
gency while driving
If the windshield wipe rs are operating when
the engine is stopped, the windshield wipers
will operate in high speed operation. After
the vehicle is stopped, operation will return
to normal when the engine switch is turned
to IGNITION ON mode, or operation will
stop when the driver’s door is opened.
WARNING
■Caution regarding the use of wind-
shield wipers in AUTO mode (vehi-
cles with rain-sensing windshield
wipers)
The windshield wipers may operate
unexpectedly if the sensor is touched or
the windshield is subject to vibration in
AUTO mode. Take care that your fingers
or anything else do 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 there is no washer fluid spray
from the nozzle
Damage to the washer fluid pump may
be caused if the lever is pulled toward
you and held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.
