112 Changing bulbs

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 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 notes 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 it is necessary to switch on the windshield wipers in dry weather conditions, always use washer fluid when operating the windshield wipers.

For this reason, you should always switch off the windshield wipers in dry weather.

Vehicles with a rain sensor: in the Ä or Å position, the appropriate wiping frequency is automatically set according to the intensity of the rain. In the Å position, the rain sensor is more sensitive than in the Ä position, causing the windshield wipers to wipe more frequently. Intermittent wiping is interrupted when you stop the vehicle and open a front door. This prevents a person from being splashed inadvertently when getting into or out of the vehicle. Intermittent wiping continues when all doors are closed and Ryou depress the clutch (vehicles with

manual transmission) or

Ryou shift the automatic transmission to drive position D (vehicles with automatic transmission) or to reverse gear R or

Ryou change the wipe setting on the

combination switch.

i To prevent smearing on the windshield or

noise when wiping, wipe the windshield occasionally with washer fluid.

120 Overview of climate control systems

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.

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.

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 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.

Dual-zone automatic climate control controls the temperature and the humidity of the vehicle interior and filters out undesirable substances from the air. Dual-zone automatic climate control is only operational when the engine is running. Optimum operation is only achieved when you drive with the side windows and tilt/ sliding sunroof/panorama roof with power tilt/sliding panel closed. i Ventilate the vehicle for a brief period

during warm weather, e.g. using the convenience opening feature (Y page 84).

Setting the air vents Important safety notes 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.

In order to ensure the direct flow of fresh air through the air vents into the vehicle interior, please observe the following notes: Rkeep the air inlet between the windshield and the hood free of blockages, such as ice, snow or leaves

Rnever cover the vents or air inlet and outlet

grilles in the vehicle interior.

i For virtually draft-free ventilation, adjust

the sliders of the air vents to the center position.

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 2/3 of the way to the red area in the tachometer display.

Vehicles with automatic transmission: RIdeally, drive program C should be selected for driving the first 1000 miles (1500 km).

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.

After 1000 miles (1500 km) you may gradually bring the vehicle up to full road and engine speeds.

Additional breaking-in notes for AMG vehicles: RFor the first 1000 miles (1500 km), do not

exceed a speed of 85 mph (140 km/h). ROnly allow the engine to briefly reach a maximum engine speed of 4500 rpm.

RShift gears in good time. i Also observe these breaking-in notes

when the vehicle's engine or axle gear have been replaced.

i Always observe the respective limit

speeds.

AMG vehicles with rear axle locking differential Your vehicle is equipped with a self-locking differential on the rear axle. Change the oil after a breaking-in period of 2000 miles(3000 km) to improve protection of the rear axle differential. This oil change extends the service life of the differential. Have the oil change carried out at a qualified specialist workshop. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose.

Driving Important safety notes 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 the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.

Version: 3.0.3.6

G Warning On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. G Warning Manual transmission: Wait until the vehicle is stationary before removing the SmartKey from the starter switch. The vehicle cannot be steered when the SmartKey is removed from the starter switch. G Warning It is dangerous to shift the automatic transmission out of parking position P or neutral position N if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train.

! AMG vehicles: at low engine oil

temperatures (below 68 ‡ (+20 †), the maximum engine speed is restricted in order to protect the engine. To protect the engine and maintain smooth engine operation, avoid driving at full throttle when the engine is cold.
