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 mir-
ror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on.
Warning!
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.
Glare can endanger you and others.Warning!
G
In the 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.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.Warning!
G
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 chang-
ing lanes.

If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster
automatically turns itself back on.
