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.

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.

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

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. 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.

Climate control 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 187).

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 121). The climate control will then adjust the interior temperature to the set value much faster.

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. G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval.

respective climate control panel. The indicator lamp in the button comes on. X Switching off: Press button 1 again.

! If the rear window defroster switches off

too soon and the indicator lamp starts flashing, too many electrical consumers are operating simultaneously and there is insufficient voltage in the battery. The system responds automatically by switching the rear window defroster off.

Power tilt/sliding sunroof Opening and closing G Warning! When opening or closing the tilt/sliding sunroof, make sure there is no danger of anyone being harmed by the opening/ closing procedure. The tilt/sliding sunroof is equipped with the express operation and automatic reversal function. If in express operation mode the tilt/sliding sunroof encounters an obstruction that blocks its path, the automatic reversal function will stop the tilt/sliding sunroof and open it slightly. The tilt/sliding sunroof operates differently when the sunroof switch is pressed and held. See the “Closing when the tilt/sliding sunroof is blocked” section for details. The opening/closing procedure of the tilt/ sliding sunroof can be immediately halted by releasing the sunroof switch or, if the sunroof switch was moved past the resistance point and released, by moving the sunroof switch in any direction.

G Observe Safety notes, see page 68. G Warning! The tilt/sliding sunroof is made out of glass. In the event of an accident, the glass may shatter. This may result in an opening in the roof. In a vehicle rollover, occupants not wearing their seat belts or not wearing them properly may be thrown out of the opening. Such an opening also presents a potential for injury for occupants wearing their seat belts properly as entire body parts or portions of them may protrude from the passenger compartment.

! To avoid damaging the seals, do not transport any objects with sharp edges which can stick out of the tilt/sliding sunroof. Do not open the tilt/sliding sunroof if there is snow or ice on the roof, as this could result in malfunctions. If you cannot open or close the tilt/sliding sunroof due to a malfunction contact Roadside Assistance or an authorized Mercedes-Benz Center.

Loading and storing Loading instructions G Warning! Always fasten items being carried as securely as possible using cargo tie-down rings and fastening materials appropriate for the weight and size of the load. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle. To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Do not pile luggage or cargo higher than the seat backrests. The cargo compartment is the preferred place to carry objects. Always use cargo tie- down rings, and if so equipped, always use the cargo net when transporting cargo. Never drive vehicle with the tailgate open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

Load distribution

The Gross Vehicle Weight (GVW) which is the weight of the vehicle including fuel, tools, spare wheel, installed accessories, passengers and luggage/cargo must never exceed the load limit and the Gross Vehicle Weight Rating (GVWR) for your vehicle as specified on the placard located on the driver’s door B-pillar (Y page 248). In addition, the load must be distributed in such a way so that the weight on each axle never exceeds the Gross Axle Weight Rating (GAWR) for the front and rear axle. The GVWR and GAWR for your vehicle are indicated on the certification label located on the driver’s door B-pillar (Y page 248). For more information, see “Tire and Loading Information” (Y page 248).

The handling characteristics of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to the illustration shown, with the heaviest items being placed towards the front of the vehicle. Please pay attention to and comply with the following instructions when loading the vehicle and transporting cargo: RAlways place items being carried against front or rear seat backrests, and fasten them as securely as possible.

RThe heaviest portion of the cargo should always be kept as low as possible against front or rear seat backrests.

For additional safety when transporting cargo while the rear seats are unoccupied, fasten the outer seat belts crosswise into the opposite side buckles.

i The cargo compartment is the preferred place to carry objects. The expanded cargo volume (Y page 211) should only be used for items which do not fit in the cargo compartment alone.

Expanding cargo volume You can separately fold the left and right rear seat backrests to expand the cargo volume. G Warning! When expanding the cargo volume, always fully fold the corresponding seats and, if so equipped, always use the cargo net when transporting cargo. Unless you are transporting cargo, the seat backrests must remain properly locked in the upright position. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
