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

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. If it is necessary to switch on the windshield wipers in dry weather conditions, always

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

during warm weather, e.g. using the convenience opening feature (Y page 89). 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.

Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.
Overview of climate control systems Important safety guidelines 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. 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.

Switching cooling with air dehumidification on/off 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 automatic climate control 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.

Problems with the rear window heating If the indicator lamp in the ª rear window heating button flashes, the on-board voltage is too low or the roof is open. The rear window heating has deactivated itself prematurely or cannot be activated. X Switch off any consumers that are not required, e.g. reading lamps or interior lighting. When the battery is sufficiently charged, the rear window heating is activated again automatically.
Activating/deactivating air- recirculation mode You can deactivate the flow of fresh air if unpleasant odors are entering the vehicle from outside. The air already inside the vehicle will then be recirculated. The operation of the air-recirculation mode is the same for all control panels. G Warning Fogged windows impair visibility, endangering you and others. If the windows begin to fog on the inside, switching off the air recirculation mode immediately should clear interior window fogging. If interior window fogging persists, make sure the air conditioning is activated, or press the ¬ button.

Setting the air vents Important safety guidelines 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 could 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.

temperatures exceed 79 ‡ (26 †). After
about 30 minutes, outside air will be
added.22
Switching the residual heat on/off It is possible to make use of the residual heat of the engine to continue heating the stationary vehicle for up to 30 minutes after the engine has been switched off. The heating time depends on the temperature that has been set. i The blower will run at a low speed
regardless of the airflow setting.

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.
Notes on breaking-in a new vehicle The first 1000 miles (1500 km) The more you look after the engine when it is new, the happier you will be with its performance in the future. RDrive at varying vehicle speeds and engine speeds for the first 1000 miles (1500 km) for this reason.
RAvoid overstraining the vehicle during this
period, e.g. driving at full throttle.
RChange gear in good time, at the latest when the tachometer needle is ⅔ of the way to the red area in the tachometer display.
RDo not manually shift to a lower gear to
brake the vehicle.
RIf possible, do not depress the accelerator
pedal past the point of resistance (kickdown).
ROnly select shift ranges 3, 2 or 1 when
driving slowly, e.g. in mountainous terrain. RIf possible, drive in drive program C for the
first 1000 miles (1500 km).
After 1000 miles (1500 km), you can increase the engine speed gradually and bring the vehicle up to full speed. i Also, observe these breaking-in notes
when the vehicle's engine, front-axle transmission or differential have been replaced.
i Always observe the respective speed
restrictions.
Driving Important safety guidelines G Warning Make sure absolutely no objects are obstructing the pedals' range of movement. Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure the pedals still have sufficient clearance. During sudden driving or braking maneuvers
