Cruise control The cruise control maintains the speed you set for your vehicle automatically. The use of the cruise control is recommended for driving at a constant speed for extended periods of time. The currently set speed or last set speed (“Resume” function) appears in the multifunction display for approximately 2 seconds. i The cruise control should not be activated

during off-road driving. G Warning! The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle’s speed and for safe brake operation. Only use the cruise control if the road, traffic, and weather conditions make it advisable to travel at a constant speed. RThe use of the cruise control can be

dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed.

RThe use of the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.

Notes on climate control system The climate control system 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. It can only function optimally when you are driving with the windows and the tilt/sliding sunroof closed. 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 (Y page 121) is deactivated. 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.

X 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 82). The climate control will then adjust the interior temperature to the set value much faster.

Air conditioning The air conditioning is operational while the engine is running and cools the interior air to the temperature set by the operator. In addition, the air conditioning dehumidifies the interior air and helps prevent window fogging. G Warning! If you switch off the cooling function, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.

The air conditioning uses the refrigerant R134a. This refrigerant is free of CFCs which are harmful to the ozone layer. ! If the air conditioning cannot be activated

again, this indicates that the air conditioning is losing refrigerant. The compressor has turned off. Have the air conditioning checked at the nearest authorized Mercedes-Benz Center.

Automatic mode When operating the climate control system in automatic mode, the interior air temperature, air volume and air distribution are adjusted automatically. In automatic mode, cooling with dehumidification is switched on. This function can be switched off if necessary. G Warning! If you switch off the cooling function, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.

i If you turn the temperature control fully clockwise or counterclockwise for one side of the vehicle, you are increasing or decreasing the temperature for the other side of the vehicle as well.

Adjusting 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.
