Severe conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A 
clogged filter will reduce the air volume 
to the interior.
If the vehicle interior is hot, ventilate 
the interior before driving off.
Keep the air intake grille in front of the 
windshield free of snow and debris.
Do not touch the interior temperature 
sensor to maintain a precise tempera-
ture.
The set value is indicated by a lighted 
segment on the control wheels.
