Climate control
The climate control is operational whenev-
er the engine is running. You can operate 
the climate control system in either the 
automatic or manual mode. The system 
cools or heats the interior depending on 
the selected interior temperature and the 
current outside temperature.
Nearly all dust particles, pollutants and 
odors are filtered out before outside air en-
ters the passenger compartment through 
the air distribution system.
The air conditioning will not engage (no 
cooling) if the A/C mode is deactivated 
(
Warning!
G
When operating the climate control, the air 
that enters the passenger compartment 
through the air vents can be very hot or very 
cold (depending on the set temperature). 
This may cause burns or frostbite to unpro-
tected skin in the immediate area of the air 
vents.
Always keep sufficient distance between un-
protected parts of the body and the air 
vents. If necessary, use the air distribution 
controls (
page 220) to direct the air to air 
vents in the vehicle interior that are not in 
the immediate area of unprotected skin.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up, 
impairing visibility and endangering you and 
others.

Severe conditions (e.g. strong air pollution) 
may require replacement of the filter 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, see “Summer opening fea-
ture” (
page 254). The climate control will then 
adjust the interior temperature to the set value 
much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
