gear R. The COMAND system display will show the area behind the vehicle with guidelines. G Warning! Please note that objects which do not touch the ground may appear to be further away than they actually are, for example: Rthe bumper of a vehicle parked behind you Ra trailer hitch Rthe back of a truck In such cases, you should not use the guidelines to judge the distance. You may misjudge the distance which increases the risk of impacting the objects. Even when the object you approach is directly on the ground do not approach the object any closer than the red guideline.

Overview of climate control system functions and air vents

Your vehicle is equipped with either of the following climate control systems: 3-zone automatic climate control Climate control (Y page 164)

USA only (Y page 170)

Canada only (Y page 172) The 3-zone automatic climate control combines an automatic heating and ventilation system with a cooling system. You can adjust the 3-zone automatic climate control separately for each zone in the vehicle.

Air vents G 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 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 adjustment to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

The climate control combines an automatic heating and ventilation system with a cooling system. You can adjust the automatic climate control separately for the driver’s and passenger side.

Rear automatic climate control (Y page 174)

The rear automatic climate control allows separate climate settings for the rear compartment.

For best possible performance of the climate control: X Keep the air intake grille in front of the

windshield free of snow, leaves, sticks, and any other debris.

X Always keep all air vents and grilles in the

passenger compartment free from obstruction.

i For draft-free ventilation, move the

adjustable center and side air vents to the middle position.

Notes on climate control The climate control is operational whenever 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 enters the passenger compartment through the air distribution system. G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement 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 Center. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (Y page 167). G Warning! Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up,

impairing visibility and endangering you and others. Keep the air intake grille in front of the windshield free of snow and debris. i If the vehicle interior is hot, ventilate the

interior before driving off, see “Summer opening feature” (Y page 108). The climate control will then adjust the interior temperature to the set value much faster.

Deactivating the climate control system G Warning! When the climate control system is switched off, the outside air supply and circulation are also switched off. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.
