If you are driving at speeds above approximately 16 mph (25 km/h): The headlamp range is set automatically depending on the distance between the vehicle and other road users. If you are driving at speeds above approximately 19 mph (30 km/h) and no other road users have been detected: The high-beam headlamps are switched on automatically. The K indicator lamp in the instrument cluster also lights up. If you are driving at speeds below approximately 16 mph (25 km/h) or other road users have been detected or the roads are adequately lit:
You can use this function to set the headlamps to change between low beam and high beam automatically. The system recognizes vehicles with their lights on, either approaching from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to low beam. The system automatically adapts the low- beam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it reactivates the high-beam headlamps.
The high-beam headlamps are switched off automatically. The K indicator lamp in the instrument cluster goes out. The _ indicator lamp in the multifunction display remains lit.

Replacing bulbs Important safety notes G WARNING Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you could burn yourself on these components. There is a risk of injury. Allow these components to cool down before changing a bulb. Vehicles with static LED headlamps: Do not use a bulb that has been dropped or if its glass tube has been scratched. The bulb may explode if: Ryou touch it Rit is hot Ryou drop it Ryou scratch it Only operate bulbs in enclosed lamps designed for that purpose. Only install spare bulbs of the same type and the specified voltage. Marks on the glass tube reduce the service life of the bulbs. Do not touch the glass tube with your bare hands. If necessary, clean the glass tube when cold with alcohol or spirit and rub it off with a lint-free cloth. Protect bulbs from moisture during operation. Do not allow bulbs to come into contact with liquids. Replace only the bulbs listed (Y page 137). 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. 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 Switching the windshield wipers on/ off ! 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.
! 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.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions, the windshield wipers may be activated inadvertently. This could then damage the windshield wiper blades or scratch the windshield. For this reason, you should always switch off the windshield wipers in dry weather.

Replacing the wiper blades Important safety notes G WARNING If the windshield wipers begin to move while you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of injury. Always switch off the windshield wipers and ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper arm of the wiper.
! Never open the hood/tailgate if a wiper
arm has been folded away from the windshield/rear window. 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 wiper arm without a wiper blade and it falls onto the windshield/rear window, the windshield/rear window may be damaged by the force of the impact. Mercedes-Benz recommends that you have the wiper blades changed at a qualified specialist workshop.
Depending on the equipment level of your vehicle, there are two variants of wiper blade; these are installed and removed in different ways. Based on the diagrams, check which system is installed in your vehicle.

i The integrated filter filters out most
particles of dust and soot and completely filters out pollen. It also reduces gaseous pollutants and odors. 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. 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 automatic climate control.

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 Read the information on qualified specialist workshops: (Y page 26).
Notes on breaking-in a new vehicle Important safety notes New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal.
The first 1000 miles(1500 km) The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. RYou should therefore drive at varying vehicle and engine speeds for the first 1000 miles (1500 km).
RAvoid heavy loads, e.g. driving at full
throttle, during this period.
RChange gear in good time, before the
tachometer needle is Ô of the way to the red area of the tachometer.
RIf possible, do not depress the accelerator
pedal past the point of resistance (kickdown).
After 1000 miles (1500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed.
Additional breaking-in notes for AMG vehicles: RDo not drive faster than 85 mph
(140 km/h) for the first 1,000 miles (1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time. i You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced.
i Always observe the respective speed
limits.
AMG vehicles with self-locking rear axle differential Your vehicle is equipped with a self-locking differential on the rear axle. To protect the differential on the rear axle, carry out an oil change after a breaking-in phase of 2,000 miles (3,000 km). This oil change
