■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for anextended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, driv e as slowly as possible to avoid damaging the wheels, underside of the vehicle, etc.
●RC200t: Make sure to idle the engine immediately after high-load driving. Stop theengine only after the turbocharger has cooled down.Failure to do so may cause damage to the turbocharger.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 619, 633)
■When encountering flooded roads

●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission, dif-
ferentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where possible), and the function of all joints, bearings, etc.

■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.

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.

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

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
