Vehicle equipment

i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.

Exterior lighting Important safety guidelines 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.

Notes on 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 oncoming traffic from being dazzled. Symmetrical lights do not illuminate as large an area of the edge of the carriageway. 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 when returning.

Changing bulbs Important safety guidelines Xenon bulbs If your vehicle is equipped with Xenon bulbs, you can recognize this by the following: the cone of light from the Xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be observed, the lights must be switched on before starting the engine. G Warning! 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 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.

Overview: changing bulbs/bulb types You can change the following bulbs. The bulb type can be found in the legend.

Halogen headlamps : Low-beam headlamp: H7 55 W ; High-beam headlamp: H7 55 W = Parking lamp/standing lamp: W 5 W ? Turn signal lamp: 3457A A Side marker lamp: WY 5 W

Bi-Xenon headlamps : High-beam headlamp: H7 55 W ; Parking lamp/standing lamp: W 5 W = Turn signal lamp: 3457A ? Side marker lamp: WY 5 W

Other bulbs 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.

There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 112). 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.

Windshield wipers Important safety guidelines 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 windows 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/rear window can scratch the glass if wiping takes place when the windshield/rear window is dry.

Replacing the wiper blades Important safety guidelines 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 can 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.
