WARNING BLIS does not react to cyclists or mopeds. BLIS does not react to vehicles that are standing still. The function of the BLIS cameras may be affected by intense light, or when driving at night in areas where there are no external sources of light (e.g., street lights, other vehicles, etc.). In such cases, the system may react as if the cameras were obscured. In both of the above mentioned conditions, a message will appear in the information display. When driving in such conditions, the system's function will be limited or it may be temporarily switched off. See page 162 for instructions. When the message is no longer displayed, BLIS will return to normal function. The BLIS cameras have the same limitation as the human eye. In other words, their "vision is impaired" by adverse weather conditions such as heavy snowfall, dense fog, etc. 161 06 Starting and driving Blind Spot Information System (BLIS)-option Limitations In certain situations, the BLIS indicator light(s) may illuminate even when there are no other vehicles in the area monitored by the system. NOTE If the BLIS indicator lights illuminate occasionally even when there are no other vehicles in the blind area, this does not indicate a fault in the system. In the event of a fault, Blind spot syst. service required will be displayed. The following are several examples of situations in which the BLIS indicator light(s) may illuminate even when there are no other vehicles in the area monitored by the system. Cleaning the BLIS camera lenses In order to function optimally, the BLIS camera lenses must be kept clean. They can be wiped clean with a soft cloth or wet sponge. CAUTION Clean the lenses carefully to avoid scratching. The lenses are electrically heated to help melt ice or snow. If necessary, gently brush away snow from the lenses. 162 06 Starting and driving
