The Automatic High Beam can be operated when
The power switch is in ON mode.
Camera sensor detection information
High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees
High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
House lights, street lights, red traffic signals, and illuminated billboards or signs
may cause the high beam to turn off.
The following factors may affect the amount of time taken to turn high beam on
or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and pre-
ceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When an oncoming or preceding vehicle only has operational lights on one
side
• When an oncoming or preceding vehicle 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
High beam may be turned on or off when unexpected by the driver.
Small vehicles, such as bicycles, may not be detected.
In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beams on or off
manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or
fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off,
dirty, changing color, or have improperly adjusted aim.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads 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.
• There is a highly reflective object ahead of the vehicle, such as a sign or a
mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or distress
to other drivers or pedestrians nearby.

Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
The turn signal lever is operated.
The vehicle speed deviates from the operating range of the LDA system func-
tions.
When the lane lines cannot be recognized while driving.
When the lane departure warning sounds.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while
the audio system or air conditioning system is in use, it may be difficult to hear
the warning sound.
After the vehicle has been parked in the sun
The LDA system may not be available and a warning message (P. 518) will be
displayed for a while after driving has started. When the temperature in the cabin
decreases and the temperature around the camera sensor (P. 264) becomes suit-
able for its operation, the functions will begin to operate.
If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane markers
could not be recognized.
Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly. How-
ever, this does not indicate a malfunction.
When driving through an area with no lane markers, such as a tollbooth, a
crossing or before a ticket checkpoint
When driving on a sharp curve
When lane markers are extremely narrow or extremely wide
When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
When the following distance between your vehicle and the vehicle ahead is
extremely short
When the lane markers are yellow (These may be more difficult for the system
to recognize compared to white markers.)
When the lane markers are broken, Botts’ dots (raised pavement markers) or
stones
When the lane markers are on a curb etc.
When lane markers are obscured or partially obscured by sand, dirt, etc.
When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
When driving on a particularly bright road surface, such as concrete

Situations in which the tire pressure warning system may not operate properly
In the following cases, the tire pressure warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• Lock nuts are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with tire pressure warning valves and transmitters are
used.
• If the ID code on the tire pressure warning valves and transmitters is not reg-
istered in the tire pressure warning computer.
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
• When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
When tire inflation pressure declines rapidly for example when a tire has burst,
the warning may not function.
The initialization operation
Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire infla-
tion pressure adjustment.
If you have accidentally turned the power switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart auto-
matically when the power switch has been turned to ON mode for the next time.
If you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are cold,
and conduct initialization again.
Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance with
the conditions under which it was initialized. For this reason, the system may
give a warning even if the tire pressure does not reach a low enough level, or if
the pressure is higher than the pressure that was adjusted to when the system was
initialized.
