Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 20).

Exterior lighting Important safety notes For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations. In these countries, the daytime running lamps are automatically switched on when the engine is started.

Information about driving abroad To convert to symmetrical low beam when driving abroad: switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road from the country where the vehicle is registered. This prevents glare to oncoming traffic. Symmetrical lights do not illuminate as large an area of the edge of the road. Have the headlamps converted at a qualified specialist workshop as close to the border as possible before driving in these countries. To convert to asymmetrical low beam after returning: have the headlamps converted back to asymmetrical low beam at a qualified specialist workshop as soon as possible after crossing the border and returning to the original country.

Replacing bulbs Important safety notes Xenon bulbs G DANGER Xenon bulbs carry a high voltage. You could get an electric shock and be seriously or even fatally injured if you touch the electric contacts on Xenon bulbs. Therefore, never remove the cover from Xenon bulbs. Do not change the Xenon bulbs yourself, but have them replaced at a qualified workshop.

Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

Other bulbs G WARNING Bulbs and lamps can become very hot. For this reason, allow them to cool down before changing them. Otherwise, you could burn yourself when you touch them. Keep bulbs out of the reach of children. Otherwise, they could, for example, damage the bulbs and injure themselves. Never use a bulb which has been dropped. Such a bulb may explode and injure you. Halogen bulbs are pressurized and could explode when you change them, especially if they are very hot. You should therefore wear eye protection and gloves when you are changing them.

There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 95). Have the bulbs that

you cannot replace yourself changed at a qualified specialist workshop. If you require assistance changing bulbs, consult a qualified specialist workshop. Do not touch the glass tube of new bulbs with your bare hands. Even minor contamination can burn into the glass surface and reduce the service life of the bulbs. Always use a lint- free cloth or only touch the base of the bulb when installing. Only use bulbs of the correct type. If the new bulb still does not light up, consult a qualified specialist workshop. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

Windshield wipers Important safety notes G WARNING The windshield will not longer be wiped properly if the wiper blades are worn. This could prevent you from observing the traffic conditions, thereby causing an accident. Replace the wiper blades twice a year, ideally in spring and fall.

! Do not operate the windshield wipers when the windshield is dry, as this could damage the wiper blades. Moreover, dust that has collected on the windshield/rear window can scratch the glass if wiping takes place when the windshield/rear window is dry. If it is necessary to switch on the windshield wipers in dry weather conditions, always use washer fluid when operating the windshield wipers.

! If the windshield wipers leave smears on

the windshield/rear window after the vehicle has been washed in an automatic car wash, this may be due to wax or other residue. Clean the windshield/rear window with washer fluid after an automatic car wash.

! To avoid damaging the wiper blades,

make sure that you touch only the wiper arm of the wiper.

! Never open the hood if a windshield wiper

arm has been folded away from the windshield. Never fold a windshield wiper arm without a wiper blade back onto the windshield/ rear window. Hold the windshield wiper arm firmly when you change the wiper blade. If you release the windshield wiper arm without a wiper blade and it falls onto the windshield, the windshield may be damaged by the force of the impact. Mercedes-Benz recommends that you have the wiper blades changed at a qualified specialist workshop.

104 Overview of climate control systems

i Ventilate the vehicle for a brief period

during warm weather, e.g. using the convenience opening feature (Y page 69). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly.

i The integrated filter can filter out most

particles of dust, and completely filters out pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Maintenance Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet.

Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 20).

Overview of climate control systems Important safety notes 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 blocked filter replaced at a Mercedes- Benz Center as soon as possible. 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.

Automatic climate control controls the temperature and the humidity in the vehicle interior and filters undesirable substances from the air. The automatic climate control is only operational when the engine is running4. Optimum operation is only achieved if you drive with the side windows and sliding sunroof closed.

4 The residual heat function can only be switched on/off if the ignition is switched off.

Operating the climate control system Notes on using dual-zone automatic climate control The following contains notes and recommendations on optimum use of dual- zone automatic climate control.

RActivate climate control using the à and Á buttons. The indicator lamps above the à and Á buttons light up. RSet the temperature to 72 ‡ (22 †). ROnly use the "defrosting" function briefly

until the windshield is clear again.

ROnly use "air-recirculation" mode briefly, e.g. if there are unpleasant outside odors or when in a tunnel. The windows could

otherwise fog up as, in air-recirculation mode, no fresh air is drawn into the vehicle. RUse the residual heat function if you want

to heat or ventilate the vehicle interior when the ignition is switched off. The "residual heat" function can only be activated or deactivated with the ignition switched off.

RAt very low temperatures, the rear window

defroster is only switched on once the vehicle interior has warmed up.

Activating/deactivating climate control Important information G WARNING When the climate control system is deactivated, the outside air supply and circulation are also deactivated. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.

i Switch on climate control primarily using

the à button (Y page 107).

Activating/deactivating X Turn the SmartKey to position 2 in the

ignition lock.

X To switch on: turn control : clockwise to

the desired position (except position 0) (Y page 105).

X The previously selected settings come into

effect again.

X To switch off: turn control : counter-

clockwise to position 0(Y page 105).

Activating/deactivating the cooling with air dehumidification function Important information The cooling with air dehumidification function is only available when the engine is running. The air inside the vehicle is cooled and dehumidified according to the temperature selected. 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.

Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal and not a sign that there is a malfunction. i The cooling with air dehumidification function uses refrigerant R134a. This coolant does not contain chlorofluorocarbons, and therefore does not damage the ozone layer.

Activating/deactivating ! If the cooling with air dehumidification does not switch on, it is possible that the climate control system has lost coolant. Have the cooling with air dehumidification checked at a qualified specialist workshop.

X To activate: press the Á button.

The indicator lamp in the Á button lights up.

X To switch off: press the Á button.

The indicator lamp in the Á button goes out. The cooling with air dehumidification function has a delayed switch-off feature.

Operating the climate control system 107

Problems with the cooling with air dehumidification function If the indicator lamp in the Á button does not go out or flashes when switched on, the cooling with air dehumidification function is switched off due to a malfunction. You can no longer switch on the cooling with air dehumidification function. X Consult a qualified specialist workshop.

Setting climate control to automatic 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.

In automatic mode, the set temperature is maintained automatically at a constant level. The system automatically regulates the temperature of the dispensed air, the airflow and the air distribution. Automatic mode will achieve optimal operation if cooling with air dehumidification is also activated. If desired, cooling with air dehumidification can be deactivated. X Turn the SmartKey to position 2 in the

ignition lock.

X Set the desired temperature. X To switch on: press the à button.

The indicator lamp in the à button lights up. Automatic air distribution and airflow are activated.

X To switch off: press the à button.

The indicator lamp in the à button goes out. Automatic air distribution and airflow are deactivated.
