The system illuminates an alert indicator in the outside mirror on the side of your vehicle the approaching vehicle is coming from. When the system is alerting on a vehicle and the corresponding turn signal is on, the alert indicator flashes at an increased level. The alert indicator dims when the system detects nighttime darkness. Blocked Sensors

A "blocked" condition can be cleared in two ways: • After the blockage in front of the sensors is removed or the rainfall/snowfall rate decreases or stops, drive for a few minutes in traffic to allow the sensors to detect passing vehicles. • By cycling the ignition from on to off, and then back on. Note: If your vehicle has a tow bar with a factory equipped trailer tow module and it is towing a trailer, the sensors automatically turn the systemoff. If your vehicle has a tow bar but no factory equipped trailer tow module, it is recommended that you turn the system off manually. Operating the system with a trailer attached causes poor system performance. SystemErrors If the system senses a problem with the left or right sensor, the warning indicator illuminates and a message appears in the information display. See Information Messages (page 118). Switching the SystemOn and Off Note: The system remembers the last setting when you start your vehicle. You can temporarily switch the system off in the information display. See General Information (page 104). Whenyou switch the system off, the information display shows a systemoff message, the indicator illuminates and you no longer receive alerts. When you switch the system on or off, the alert indicators flash twice. You can also have the systemswitched off permanently at an authorized dealer. Once the system is switched off permanently at an authorized dealer, only an authorized dealer can turn the system back on.

The system uses radar sensors that are located near the rear bumper on each side of your vehicle. Any dirt, mud or snow in front of the sensors or driving in heavy rain can cause system degradation and false alerts. Also, other types of obstructions in front of the sensor can cause system degradation. This is referred to as a ‘blocked’ condition. Note: Do not apply bumper stickers and/or repair compound to these areas, this can cause degraded system performance. Note: The alert indicator may turn on during heavy rain even though no vehicle has entered the blind zone. If the system detects a degraded performancecondition, amessagewarning of a blocked sensor appears in the information display. The alert indicators remain on and the system no longer provides any vehicle warnings. You can clear the information display warning but the alert indicators remain illuminated.
