Rear view mirror
Automatic antiglare rear view mirror
The reflection brightness of the exterior 
rear view mirror on the driver’s side and 
the inside rear view mirror will respond au-
tomatically to glare when
the ignition is switched on, and
incoming light from headlamps falls on 
the sensor in the inside rear view 
mirror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
Warning!
G
The automatic antiglare function does not 
react if incoming light is not aimed directly 
at sensors in the inside rear view mirror.
The inside 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.
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 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.
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.!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.
