Information on the windshield wipers
(page 47) and for setting the rear view
mirrors (
page 38) is found in the “Get-
ting started” section.
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 mir-
ror.
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 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 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.
