pushed rearward (hit from the front), press
button1 to fold mirrors in, then press
button1 again to fold mirrors out. Do not force
mirrors by hand as this may damage the adjust-
ment mechanism.

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, if the rear window sun-
shade 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 con-
ditions and could cause an accident.Warning!
G
In case of an accident, liquid electrolyte may
leak from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low 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 re-
moved only while in the liquid state by applying
plenty of water.
Warning!
G
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 in-
side rear view mirror or glance over your
shoulder before changing lanes.
