■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insuff icient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning ( P. 238) will not be activated, which may lead to an accident resulting in
death or serious injury.
●Vehicles with small rear ends (traile rs with no load on board, etc.)
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane

■Conditions under which the vehicle-to-vehic le distance control mode may not func-
tion correctly
Operate the brake pedal (or accelerator pe dal operation depending on the situation)
as necessary in the following conditions as the radar sensor may not be able to cor-
rectly detect vehicles ahead, which may lead to an accident resulting in death or seri-
ous injury.
●When the road curves or when the lanes are
narrow
●When steering wheel operation or your posi-
tion in the lane is unstable
●When the vehicle ahead of you decelerates
suddenly

■Handling the radar sensor
Observe the following to ensure the dynamic radar cruise control can function effec-
tively.
Otherwise, the radar sensor may not detect correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surr ounding area to a strong impact.
If the sensor moves even slightly off posi tion, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●If the radar sensor needs to be replaced, contact your Lexus dealer.

2484-5. Using the driving support systems
RC350/RCF_U (OM24636U)
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 deviated from its lane, it alerts the driver
using a buzzer and indications on the multi-information display.

■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 necessar y 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 no t 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. 544) will be dis-
played for a while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor ( P. 233) becomes suitable for its
operation, 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 functi on may not operate correctly
In the following situations, the 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 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 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

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.
If any suspension parts need to be replaced, contact your Lexus dealer.
●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
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.
●Do not spill liquid onto the camera sensor.
●Do not attach window tinting to the windshield.
●Do not install an antenna in front of the camera lens.
●If the area of the windshield in front of the camera sensor is fogged up, use the wind-
shield defogger to remove the fog.
When it is cold, setting the heater to blow air to the feet only may cause the area of
the windshield in front of the camera sensor to fog up. This will have a negative effect
on the images.
●Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield , be careful not to get any glass cleaner
etc. on the lens. Also, do not touch the lens.
For lens repair, contact your Lexus dealer.
●Do not change the installation position or di rection of the camera sensor or remove it.
The direction of the camera se nsor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disassemble
the camera sensor.
●If the windshield needs to be re placed, contact your Lexus dealer.
●Do not attach a sticker or other items to the
windshield near the camera sensor.
