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.
Information about driving abroad Converting 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 to 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, e.g. an authorized Mercedes-Benz Center, as close to the border as possible before driving in these countries. Converting to asymmetrical low beam after returning: have the headlamps converted back to asymmetrical low beam at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center, as soon as possible after crossing the border again. 5 Only vehicles with front fog lamps have the fog lamps function.

fatally injured if you touch the electric contacts on Xenon bulbs. Therefore, never remove the cover from Xenon bulbs. Do not change Xenon bulbs yourself, but have them replaced at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at 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.
Other bulbs There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 123). Have the bulbs that you cannot replace yourself changed at a qualified specialist workshop. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out 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. G WARNING Bulbs and lamps can be very hot. You should therefore allow them to cool down before you change them. Otherwise, you could be burned if you touch them. Keep bulbs out of the reach of children. Otherwise, they could damage the bulbs, for example, and injure themselves. Never use a bulb which has been dropped. Such a bulb may break or even explode and injure you. Halogen bulbs are pressurized and can explode when you change them, particularly if they are very hot. You should therefore wear eye protection and gloves when you are changing them.
Overview: changing bulbs/bulb types You can change the following bulbs. The bulb type can be found in the legend.

Windshield wipers Switching the windshield wipers on/ off G WARNING Wiper blades are components that are subject to wear and tear. Replace the wiper blades twice a year, preferably in the spring and fall. Otherwise the windshield will not be wiped properly. As a result, you may not be able to observe surrounding traffic conditions and could cause an accident.
! 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 can scratch the glass if wiping takes place when the windshield is dry.
! If the windshield wipers leave smears on the windshield after the vehicle has been washed in an automatic car wash, wax or other residues may be the reason for this. Clean the windshield using washer fluid after washing the vehicle in an automatic car wash.

Replacing the wiper blades Important safety notes G WARNING For safety reasons, switch off the windshield wipers and remove the key from the ignition lock before changing the wiper blades (vehicles with KEYLESS-GO: make sure that the on-board electronics are in state 0). Otherwise, the wiper motor could be switched on suddenly and cause injury.
! 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. 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 replaced by a qualified specialist workshop, e.g. at an authorized Mercedes-Benz Center.
Replacing the wiper blades Removing the wiper blades X Remove the SmartKey from the ignition
lock or turn it to position 0 (KEYLESS-GO).

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 Service Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i It is possible that the residual heat
function may be activated automatically an hour after the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the air-conditioning system.

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 23).
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.
The automatic climate control adjusts the temperature and the humidity of the vehicle interior and filters undesired substances from the air. The automatic climate control is only operational when the engine is running.10
i Ventilate the vehicle for a brief periodduring warm weather, e.g. using the convenience opening feature (Y page 84).
