Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not automatically drive
the vehicle or reduce the amount of attention that must be paid to the area in front of
the vehicle. The driver must always assume full responsibility for driving safely by pay-
ing careful attention to the surrounding cond itions and operating the steering wheel to
correct the path of the vehicle. Also, the driver must take adequate breaks when
fatigued, such as from driving for a long period of time.
Failure to perform appropriate driving operat ions and pay careful attention may lead to
an accident, resulting in death or serious injury. ■
To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.■
Situations unsuitable for LDA system
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in death or
serious injury. ●
A spare tire, tire chains, etc. are equipped. ●
When the tires have been excessively worn, or when the tire inflation pressure is low. ●
Tires which differ by structure, manufacturer, brand or tread pattern are used. ●
Objects or patterns that could be mistaken for white (yellow) lines are present on the
side of the road (guardrails, cu rbs, reflective poles, etc.).●
Vehicle is driven on a snow-covered road. ●
White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.●
Asphalt repair marks, white (y ellow) line marks, etc. are present due to road repair.●
Vehicle is driven in a temporary lane or restricted lane due to construction work.●
Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow,
freezing, etc. ●
Vehicle is driven in traffic lanes ot her than on highways and freeways.●
Vehicle is driven in a construction zone. ●
During emergency towing ■

Situations unsuitable for dy namic radar cruise control
Do not use dynamic radar cruise contro l in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident result-
ing in death or serious injury. ●
Roads where there are pede strians, cyclists, etc.●
In heavy traffic ●
On roads with sharp bends ●
On winding roads ●
On slippery roads, such as thos e covered with rain, ice or snow●
On steep downhills, or where there are sudden changes between sharp up and down
gradients
Vehicle speed may exceed the set speed when driving down a steep hill.●
At entrances to freeways and highways ●
When weather conditions are bad enough that they may prevent the sensors from
detecting correctly (fog, snow, sandstorm, heavy rain, etc.)●
When there is rain, snow, etc. on the fron t surface of the radar sensor or camera sen-
sor ●
In traffic conditions that require frequent repeated a cceleration and deceleration●
During emergency towing ●

When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driv en safely and possibly
cause an accident. ●
Do not use the sensor at speeds in excess of 6 mph (10 km/h). ●
The sensors’ detection areas and reaction ti mes are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially th e 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 ●
RC350/RC300: The detection areas of the sensors are limited to the areas around
the vehicle’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 th e sensors to correctly detect obje cts. Pay particul ar 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 se nsor (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 bump y 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 sunlig ht 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 (lowered 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 the sensor to be closer than they
are.
