Controls in detail Mirrors Auto-dimming rear view mirrors Warning! The reflection brightness of the exterior rear view mirror on the driver's side and the interior rear view mirror will respond automatically to glare when the ignition is switched on ( page 336) and incoming light from headlamps falls on the sensor in the interior rear view mirror The interior rear view mirror will not react if reverse gear R is engaged and the interior lighting is turned on G Warning! G The auto-dimming function does not react if incoming light is not aimed directly at the sensors in the interior rear view mirror. The interior rear view mirror and the exterior rear view mirror on the driver's side do not react, for example, if the rear window sunshade is in raised position. Light hitting the mirror(s) at certain angles (incident light) could blind you. As a result, you may not be able to observe traffic conditions and could cause an accident. Exercise care when using the passenger-side exterior rear view mirror. The mirror surface is convex (outwardly curved surface for a wider field of view). Objects in mirror are closer than they appear. Check your inside rear view mirror or glance over your shoulder before changing lanes. 355
