Au tomatic dimming fun ction
The automatic dimming function is activated every time the ignition
is turned on. The green indicator lig ht is lit to ind ica te auto dimming

When dimming is activated, the inside mirror will darken
automati ­
cally
in response to the amount of light striking the mirror (such as
headlights from rearward approaching vehicles). Even in d imm ing
mode , the mirror surface turns bright when :
• the interior light is switched on
• reverse gear is engaged .

& WARNING
The glass of the inside rearview mirror is layered and contains an
electrolyte to achieve its properties. Be aware of liquid electrolyte
leaking from a broken mirror glass. This liquid can cause irritation
to skin, eyes, and respiratory system. If you get electrolyte in your
eyes or on your skin, immediately rinse with plenty of water. If irri­
tation persists, seek medical attention.
0 Note
Liquid electrolyte leaked from a broken mirror glass will damage any
plastic surfaces it comes in contact with. Clean up spilled electrolyte
immediately with clear water and a sponge.
[ i] Tips
• If you switch off the automatic dimming function on the inside
mirror, automatic dimming of the outside mirrors will likewise be
disabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any stickers to the windshield in front of the light
sensor, as this would interfere with the automatic operation of the
headlights and the automatic dimming of the inside mirror.•

Adjust your seat properly so that:
• you can easily and quickly reach all the switches and controls in
the instrumen t pa nel
• your body is proper ly supported to reduce physical stress and
f atigue
