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.

Warning!

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 (컄 page 206) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system.

Warning!

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 and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Light Truck Center.

The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 214).

Controls in detail Climate control

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.

i If the vehicle interior is hot, ventilate the in- terior before driving off, see “Summer opening feature” (컄 page 237). 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.
