2022 LEXUS ES350 headlights

1624-3. Operating the lights and wipers
●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 shown 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
• The front camera is deformed or dirty
• When the temperature of the front cam- era is extremely high
• Surrounding brightness levels are equal to those of headlights, tail lights or fog
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
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads
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 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
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in low beam position.
• Automatic High Beam switch is on.
2 Turn the engine switch to IGNITION
ON mode.
3 Within 60 seconds after 2, repeat pull-
ing the headlight switch lever to the
original position then pushing it to the
high beam position quickly 10 times,
then leave the lever in high beam posi-
tion.
4 If the sensitivity is changed, the Auto-
matic High Beam indicator turns on and
off 3 times.
Automatic High Beam (headlights) may
turn on even the vehicle is stopped.

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not auto-
matically drive the vehicle or reduce
the amount of attention that must be
paid to the area in front of the vehicle.
The driver must always assume full
responsibility for driving safely by pay-
ing careful attention to the surround-
ing conditions and operating the
steering wheel to correct the path of
the vehicle. Also, the driver must take
adequate breaks when fatigued, such
as from driving for a long period of
time.
●Failure to perform appropriate driving
operations and pay careful attention
may lead to an accident, resulting in
death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA
switch to turn the system off. Failure to do
so may lead to an acc ident, resulting in
death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven on a snow-covered
road.
●White (yellow) lines are difficult to see
due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane
or restricted lane due to construction
work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been excessively
worn, or when the tire inflation pres-
sure is low.
●During emergency towing
■Preventing LTA system malfunctions
and operations performed by mistake
●Do not modify the headlights or place
stickers, etc. on the surface of the
lights.
●Do not modify the suspension etc. If
the suspension etc. needs to be
replaced, contact your Lexus dealer.
●Do not install or place anything on the
hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar,
etc.).
●If your windshield needs repairs, con-
tact your Lexus dealer.
■Conditions in which functions may
not operate properly
In the following situations, the functions
may not operate properly and the vehi-
cle may depart from its lane. Drive safely
by always paying careful attention to
your surroundings and operate the
steering wheel to correct the path of the
vehicle without relying solely on the func-
tions.
●When the follow-up cruising display is
displayed ( P.191) and the preceding
vehicle changes lanes. (Your vehicle
may follow the preceding vehicle and
also change lanes.)
●When the follow-up cruising display is
displayed ( P.191) and the preceding
vehicle is swaying. (Your vehicle may
sway accordingly and depart from the
lane.)

■Lane departure alert function
When the system determines that the
vehicle might depart from its lane or
course
*, a warning is displayed on the
multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.
When the warning buzzer sounds or the
steering wheel vibrates, check the area
around your vehicle and carefully operate
the steering wheel to move the vehicle
back to the center of the lane.
When the system determines that the vehi-
cle might depart from its lane and that the
possibility of a collision with an overtaking
vehicle in the adjacent lane is high, the lane
departure alert will operate even if the turn
signals are operating.
*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb
