Controls in detail Good visibility Auto-dimming rear view mirrors* 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 and incoming light from headlamps falls on the sensor in the interior rear view mirror. The rear view mirror will not react if reverse gear R is engaged the interior lighting is turned on Warning! Warning! G ! Electrolyte drops coming into contact with the vehicle paint finish can be completely removed only while in the liquid state and by applying plenty of water. The auto-dimming function does not react if incoming light is not aimed directly at 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. Glare can endanger you and others. Warning! G G In case of an accident, liquid electrolyte may escape from the mirror housing if the mirror glass breaks. Electrolyte has an irritating effect. Do not allow the liquid to come into contact with eyes, skin, clothing, or respiratory system. In case it does, immediately flush affected area with water, and seek medical help if necessary. 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 interior rear view mirror or glance over your shoulder before changing lanes. 171
