■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 warn ing 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 unus ual 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 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 brig ht 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 level changes rapi dly, such as the entrance to
or exit from a tunnel
●When sunlight or the headlights 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. 517, 518)

CAUTION
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto-
matically, nor does it reduce the amount of
care you need to take. As such, the driver
must always assume full responsibility for understanding his/her surroundings, for
operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent drivin g could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using th e “LDA” switch when not in use.
■Situations unsuitable for LDA system
Do not use LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When driving with non-standard parts or aftermarket equipment installed (including
modified tires and suspensions, etc.).
●When there are objects or structures along the roadside that might be misinterpreted
as lane markers (such as guardrails, curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt, etc.
●When there are visible lines on the pavement from road repairs, or if the remains of
old lane markers are still visible on the road
●When driving in a lane other than the driving or passing lanes on a freeway or high-
way.
●When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane

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. 228)
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.

■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 follo wing 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 one 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 th e 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.

■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
(At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is detected while the re ar view monitor system, Lexus parking assist
monitor or Multi-terrain Monitor is in use, the warning indicator will appear in the upper
corner of the screen even if the display setting has been set to off.
■Sensor detectio n information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surround ing environment may affect the ability of a
sensor to correctly detect an obstacle. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e 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 co nsiderably 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 (low ered 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 a sensor to be closer than they are.
