obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
●Some pedestrians such as the following may not be detected by the radar
sensor and camera sensor, preventing the system from operating properly:
• Pedestrians shorter than approximately 1 m (3.2 ft.) or taller than approx-
imately 2 m (6.5 ft.)
• Pedestrians wearing oversized clothing (a rain coat, long skirt, etc.), mak-
