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

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.
!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.Warning!
