WARNING
■Before using LKA system
Do not rely solely upon the LKA system. LKA is not a system which automatically drives the vehicle or reduces 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 always paying careful attention to the surrounding conditions and operate the steer-ing wheel to correct the path of the vehicle. Also, make sure to take adequate breaks
when fatigued, such as from driv ing 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 LKA by mistake
When not using the LKA system, use the LKA switch to turn the system off.
■Situations unsuitable for LKA
Do not use the LKA system in the following situations. The system may not operate properly and le ad 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.

■Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily canceled. However, when the operation conditions are met again, operation of the function is auto-
matically restored. ( P. 320)
■Lane departure control function/lane-keeping assist function
Depending on the vehicle speed, lane departure situation, road conditions, etc., the
operation of the functions may not be reco gnized or the functions may not operate.
■Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio playback, etc.
Also, it may be difficult to feel steering wh eel vibrations due to the road conditions, etc.
■Hands off steering wheel alert
Except for Israel: When the system determines that the driver has removed their hands
from the steering wheel while the lane departure control function or lane-keeping assist function is operating, a warning message is displayed on the multi-information display. If the driver continues to keep their hands off of the steering wheel, the buzzer sounds, a
warning message is displayed and the function is temporarily canceled. This alert also operates in the same way when the vehicle is driven with the steering wheel lightlygripped. However, depending on the road conditions, etc., the function may not cancel.
For Israel: When the system determines that the driver has removed their hands from the steering wheel while the lane departure contro l function or lane-keeping assist function is operating, a warning message is displaye d on the multi-information display and the
buzzer sounds.
■White (yellow) lines are only on one side of road

■Lexus parking assist-sensor display
●Vehicles with a Lexus Display Audio system : When an obstacle is detected while the Lexus parking assist monitor is in use, the warning indicator will appear in the upperpart of the screen even if the display setting has been set to off.
●Vehicles with a navigation system: If the Lexu s parking assist-sensor display is set to on, detected objects will also be displayed on the panoramic view monitor. For details, refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an obstacle. Particular instances where this may occur are listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.) • 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 obstacles may not be detected. • The sensor is covered in any way.• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass. • The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, airbrakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity. • The sensor is coated with a sheet of spray or heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb. • In harsh sunlight or intense cold weather.• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor. • A non-genuine Lexus suspension (low ered suspension etc.) is installed. • People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape, signs and other objects may be judged by a sensor to be closer than they are.

WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a
safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRC/VSC system is operating. Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist co ntrol is not intended to hold the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-trol to hold the vehicle on an incline, as doing so may lead to an accident.
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary. Trailer Sway Control is part of the VSC syst em and will not operate if VSC turned off or experiences a malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tire s are inflated to the recommended tire infla-
tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional for further information when replacing tires or wheels.
