■Temporary cancelation of the LDA system
If any of the following occurs, the LDA system
will be temporarily canceled. The functions
will resume after the necessary operating conditions have returned.
●The turn signal lever is operated.
●The brake pedal is depressed.
●The vehicle speed deviates from the operating range of the LDA system.
●The lane lines cannot be recognized while driving.
●The wiper operates continuously.
●When the lane departure warning function is activated.
Once the lane departure warning function is activated, it will be temporarily canceled
and resume a few seconds later.
■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. 522) will be dis-
played for a while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor ( →P. 232) becomes suitable for its
operation, the functions will begin to operate.

■Conditions in which the function may not operate correctly
In the following conditions, th e camera sensor may be unable to recognize lane markers
causing the lane departure warning function to operate incorrectly. However, 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 ma y be more difficult for the system to rec-
ognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” 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
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light leve l changes rapidly, such as the entrance to
or exit from a tunnel
●When sunlight or the headlight s of oncoming vehicles are shining directly into the cam-
era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water,
etc.
●When the vehicle experiences strong up-and-down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when
the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages and buzzers for LDA system
Warning messages and buzzers are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. ( →P. 5 2 2 , 5 2 3 )

NOTICE
■To prevent damage to or incorrect operation of the LDA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension or replace it with non-genuine parts.
●Do not install or place anything on the hood or the grille. Also, do not install a grille
guard (bull bars, kangaroo bar etc.).
●If your windshield needs repairs, contact your Lexus dealer.
■Camera sensor ( →P. 2 3 2 )
Observe the following to ensure that the LDA system functions correctly.
●Keep the windshield clean at all times.
Performance could be affected if the windshie ld is dirty, or if raindrops, condensation
or ice are adhering to the windshield.
●Do not spill liquid onto the camera sensor.
●Do not attach window tinting to the windshield.
●Do not install an antenna in front of the camera lens.
●If the windshield is fogged up, use the windshield defogger to remove fog from the
windshield.
When it is cold, using the he ater with air blowing to the feet may allow the upper part
of the windshield to fog up. This will have a negative effect on the images.
●Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield, be careful not to get any glass cleaner
etc. on the lens. Also, do not touch the lens.
For lens repair, contact your Lexus dealer.
●Do not change the installation position or di rection of the camera sensor or remove it.
The direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disassemble
the camera sensor.
●Do not replace windshield with non-genuine windshield.
Contact your Lexus dealer.
●Do not attach a sticker or other items to the
windshield near the camera sensor.

The distance from your vehicle to nearby obstacles when parallel parking or
maneuvering into a garage is measured
by the sensors and communicated via
the multi-information display, the multimedia screen (if equipped), the naviga-
tion system screen (if e quipped), and a buzzer. Always check the surrounding
area when using this system.

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the foll
owing distance of the obstacle, the
buzzer sounds continuously. • Front corner sensors: Approximately 1.0 ft. (30 cm)
• Front center sensors: Approximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.3 ft. (40 cm)
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a long tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.6 ft. (50 cm)
Approximately 1.8 ft. (55 cm)
The diagram shows the detection range
of the sensors. Note that the sensors
may not be able to detect obstacles that
are extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object
etc.
