358 Driving systems Optical and acoustic collision warning When you switch on the appropriate turn signals to change lanes, and a vehicle is detected in the side monitoring range of Active Blind Spot Assist, you receive an optical and acoustic collision warning. You then hear a double warning tone, and red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Course-correcting brake application If Active Blind Spot Assist detects a risk of lateral collision in the monitoring range, under certain circumstances, it will brake the vehicle briefly on one side. This is designed to help you avoid a collision. This function is available in the range between 20 mph and 120 mph (30 km/h and 200 km/h). When a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and the following message, for example, appears in the multifunction display: sufficient distance to the side for other traffic or obstacles. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. Driving and parking Either a very slight course-correcting brake application, or none at all, may occur if: Rother vehicles and/or objects, such as crash barriers, are detected in the immediate vicinity of your vehicle. Ra vehicle approaches you too closely at the side. Ryou have adopted a sporty driving style with high cornering speeds. Ryou brake or accelerate decisively. Ra driving safety system intervenes, such as ESP® or PRE-SAFE® Brake. RESP® is deactivated. Ra loss of tire pressure or a defective tire has been detected and displayed. Activating Active Blind Spot Assist X Make sure that the radar sensor system (Y page 378) and Active Blind Spot Assist (Y page 376) are activated in the on-board computer. X Turn the key to position 2 in the ignition lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5 seconds and then turn yellow. G Warning Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the course-correcting brake application is not sufficient to avoid a collision. In such a case, you must steer, brake or accelerate. In very rare cases, the system may erroneously detect a danger of collision in the area of crash barriers or similar lane borders and apply the brakes. Active Blind Spot Assist does not detect all traffic situations and road users. Always make sure that there is
