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.

• Stationary objects • Vehicles which are moving away from your vehicle
• Pedestrians, motorcycles, bicycles, etc.*• Objects which are extremely close to a radar sensor • Vehicles which are approaching from the right or left at the rear of the vehicle at a
traveling speed of less than approximately 8 km/h (5 mph) • Vehicles which are approaching from the right or left at the rear of the vehicle at a traveling speed of more than a pproximately 24 km/h (15 mph)
*: Depending on conditions, detection of a vehicle and/or object may occur.
●Situations in which the radar sensors may not be able to detect an object
• When a sensor or the area around a sensor is extremely hot or cold • If the rear bumper is covered with ice, snow, dirt, etc.
• If heavy rain or water strikes the vehicle • When the detection area of a radar sensor is obstructed by an adjacent vehicle• If the vehicle is significantly tilted
• If towing eyelets are installed • If the suspension has been modified or ti res of a size other than specified are installed
• If the front of the vehicle is raised or lowered due to the carried load • If a sticker or an electronic component, such as a backlit license plate (especially flu-orescent type), fog lights, a fender pole or wireless antenna is installed near a radar
sensor • If the orientation of a radar sensor has been changed due to a collision or other
impact or removal and installation • When multiple vehicles are approaching wi th only a small gap between each vehicle • When a vehicle is approaching at high speed
●Situations in which the radar sensor may not detect a vehicle
