RC300h_EE(OM24740E)
While driving on a road that has lane markers, this system recognizes the lane
markers using a camera as a sensor to alert the driver when the vehicle deviates
from its lane.
If the system judges that the vehicle has de viated from its lane, it alerts the driver
using a buzzer and indications on the multi-information display.

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 markers, the lane line will flash in yellow. ( P. 543)
When the inside of both lane lines are
black:

●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 for the LDA system
Warning messages are used to indicate a syst em malfunction or to inform the driver of
the need for caution while driving. ( P. 549)
WARNING
■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 fo r understanding his/her surroundings, for operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■Situations unsuitable for LDA system
Do not use the 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 there are objects or structures along the roadside that might be misinterpreted as lane markers (such as guardrails, a 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 on a road with lane closures due to maintenance, or when driving in a temporary lane

Vehicles with a Lexus Display Audio system:
The distance from your vehicle to ne arby obstacles when parallel parking or
maneuvering into a garage is measured by the sensors and communicated via
the multi-information display, Lexus Display Audio screen and a buzzer.
Always check the surrounding ar ea when using this system.
Vehicles with a navigation or multimedia system:
Refer to the “NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S

WARNING
■When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driven safely and possibly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check the areas surrounding the vehicle (especially the sides of the vehi-cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
■Limitations of the sensors
●The detection areas of the sensors are limited to the areas around the vehicle’s front
and rear bumpers.
●Certain vehicle conditions and surrounding environments, such as the following, may affect the ability of the sensors to correctly detect objects. Pay particular attention in
the following situations. Failure to do so may result in the vehicle being driven unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a sens or (Cleaning the sensor will resolve this
problem.) • When 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 objects may not be detected • When a sensor is covered in any way• When the vehicle is leaning considerably to one side
• When driving on an extremely bumpy road, incline, gravel, or grass • When 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
• When there is another vehicle equipped with parking assist sensor in the vicinity • When the sensor is coated with a sheet of spray or heavy rain• When the vehicle is equipped with a fender pole or wireless antenna
• When a towing eyelet is installed • When a bumper or sensor receives a strong impact• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlight or intense cold weather • When an object is directly under a bumper• When objects become too close to the sensors
• When a non-genuine Lexus suspension (l owered suspension, etc.) is installed In addition to the situations above, there are instances in which, because of theirshape, signs and other objects may be judged by the sensor to be closer than they
are.
