Controls in detail Climate control

The climate control is operational when- ever the engine is running. You can oper- ate 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 mode ACOFF is activated or mode A/C is deactivated (컄 page 185).

Warning!

Warning!

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.

When operating the climate control, the air that enters the passenger compartment through the air vents in the footwell can be very hot or very cold (depending on the set temperature). This may cause burns or frost- bite on unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the footwell air vents. If necessary, change the air flow using the air distribution controls to direct the air away from the foot- well air vents (컄 page 182).

180

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 “Opening (Summer opening feature)” (컄 page 247). Keep the air intake grille in front of the windshield free of snow and debris. Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window.
