■If a battery terminal has been disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the vehicle stra ight ahead for 5 seconds or more at a speed
of approximately 35 km/h (22 mph) or more.
■If “ICS Unavailable” is displayed on the mu lti-information display and the ICS OFF indi- cator is flashing
●A sensor may be covered with ice, snow, dirt , etc. Remove the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, due to ice forming on a sensor at low temperatures, a warning message may be
displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to normal.
●If this message continues to be displayed even after cleaning the sensor, or is displayed
even though the sensor is clean, have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Initialization may not have been performed after a battery terminal was disconnected
and reconnected. Initialize the system. ( P. 391)
■If “ICS Malfunction Visit Your Dealer” is displayed on the multi-information display and the ICS OFF indicator is flashing
The system may be malfunctioning. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

WARNING
■Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an accident.
●The driver is solely responsible for safe dr iving. Always drive carefully, taking care to
observe your surroundings. The Intelligent Clearance Sonar system is designed to provide support to lessen the severity of collisions. However, it may not operate in some situations.
●The Intelligent Clearance Sonar system is not designed to stop the vehicle com- pletely. Additionally, even if the system has stopped the vehicle, it is necessary todepress the brake pedal immediately as brak e control will be canceled after approxi-
mately 2 seconds.
■To ensure the Intelligent Clearance Sonar system can operate properly
Observe the following precautions regarding the sensors ( P. 383). Failure to do so
may cause a sensor to not operate properly, and may cause an accident.
●Do not modify, disassemble or paint the sensors.
●Do not replace a sensor with a part other than a genuine part.
●Do not subject a sensor or its surrounding area to a strong impact.
●Do not damage the sensors, and always keep them clean.
Observe the following precautions regarding the radar sensors ( P. 360). Failure to
do so may cause a radar sensor to not operate properly, and may cause an accident.
●Do not modify, disassemble or paint the sensors.
●Do not replace a radar sensor with a part other than a genuine part.
●Do not subject a radar sensor or its surrounding area to a strong impact.
●Do not damage the radar sensors, and alwa ys keep the radar sensors and their sur- rounding area on the bumper clean.
■Handling the suspension
Do not modify the suspension, as changes to the height or inclination of the vehicle may prevent the sensors from detecting objects correctly or cause the system to not oper-
ate or operate unnecessarily.
