When the inside of both lane lines
turn white:
Indicates that both right and left
lane markers are recognized.
If the vehicle deviates from the lane,
the lane line on the side the vehicle
has deviated from will flash in yel-
low. (P. 514)
When the inside of either lane line
turns white:
Indicates that the lane marker on the
white-marked side is recognized.
If the vehicle deviates from the side
of a lane with recognized lane mark-
ers, the lane line will flash in yellow.
(P. 514)
When the inside of both lane lines
are black:
Indicates that no lane markers are
recognized or the LDA system is
temporarily canceled.

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

or maneuvering into a garage is measured by the sensors and communi-
cated via the multi-information display, Lexus Display Audio screen (if
equipped) and a buzzer. Always check the surrounding area when using
this system.

Sensor detection information
The sensor’s detection areas are limited to the areas around the vehicle’s front
corner and rear bumpers.
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their
shape, signs and other objects may be judged by the sensor to be closer than they
are.
The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within the sen-
sor’s detection areas before the display is shown and the warning beep
sounds.
• Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or
air flow noise of the air conditioning system.
