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 (컄 page 228).

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 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 220) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Controls in detail Climate control

i 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” (컄 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.

The automatic climate control is a 3-zone intelligent automatic climate control system. Your vehicle interior is divided into 3 zones.

Warning!

When operating the automatic 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 frost- bite to unprotected skin in the immediate area of the air vents.

Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 234) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Controls in detail 3-zone automatic climate control*

With the help of a sun sensor, the automatic climate control determines the relation of the sun to the vehicle and auto- matically adjusts the inside temperature for each individual zone. The automatic climate control is oper- ational whenever the engine is running. It cools the vehicle’s interior according to the angle and intensity of the sun’s rays, the outside temperature and the selected tem- perature. You can operate the automatic climate control in either the automatic or manual mode. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 243).

Deactivating the automatic climate control system

Reactivating 왘 Press button U (컄 page 234).

i You can also press button ´ (컄 page 234) on the automatic climate control panel. If you press button 0 (컄 page 234) to reacti- vate the automatic climate control system, the defrosting mode is activated.

Follow the recommended settings for heat- ing and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others.

i 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” (컄 page 254). The automatic 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.
