■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 functions.
●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 seconds 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. 603) will be dis- played for a while after driving has started. When the temperature in the cabin decreasesand the temperature around the camera sensor ( P. 314) becomes suitable for its oper-
ation, 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 fo r 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. 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 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 partic ularly 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 level changes rapidly, such as the entrance to
or exit from a tunnel

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
●RC200t: The detection areas of the sensors are limited to the areas around the vehi- cle’s front and rear bumpers.
●RC F: The detection areas of the sensors are limited to the areas around the vehicle’s
front corners and the 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

WARNING
• 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 their shape, signs and other objects may be judged by th e sensor to be closer than they are.
●The shape of an object may prevent the sensor from detecting it. Pay particular atten-
tion to the following:
• Wires, fences, ropes, etc. • Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects •Low objects• Tall objects with upper sections projecting outwards in the direction of your vehi-
cle • People, animals and other moving objects• People wearing certain types of clothing
●The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance
may be shortened, or detection may not be possible. • Objects may not be detected if they are too close to a sensor.• There will be a short delay between the de tection of an object and display of the
detection. Even at slow speeds, there is a possibility that the object will come within a sensor’s detection area before the display is shown and a warning beep sounds.
• Thin posts or objects lower than a 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.

WARNING
■When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when backing up. When backing up, be sure to check visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or serious injuries.
●Never depend on the parking assist monitor entirely when backing up. The imageand the position of the guide lines displayed on the screen may differ from the actualstate.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●If you seem likely to hit nearby vehicles , obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condition, etc. when parking. It is necessary to be fully aware of this before using the parking assist system.
●When parking, be sure to check that th e parking space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires • When the trunk is not closed completely• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. Theimage could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check direct visually and with the mirrors all around the vehicle before proceeding.
●If the tire sizes are changed, the position of the guide lines displayed on the screen
may change.
●The camera uses a special lens. The distances between objects and pedestrians that appear in the image displayed on the screen will differ from the actual distances.
( P. 338)
●Estimated course line display mode: If the steering wheel is straight and the vehicle width guide lines and the estimated course lin es are not in alignment, have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
