Mercedes Benz 2009 M-Class User Manual

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

앫

the ignition is switched on

and

앫

incoming light from headlamps falls on 
the sensor in the interior rear view 
mirror

The rear view mirror will not react if

앫

the automatic transmission is set to 
position R

앫

the interior lighting is turned on

G

The auto-dimming function does not react if 

incoming light is not aimed directly at sen-

sors 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, when transporting cargo 

which covers the rear window.

Light hitting the mirror(s) at certain angles 

(incident light) could blind you. As a result, 

you may not be able to observe traffic con-

ditions and could cause an accident.

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 passen-

ger-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.
