X Press the combination switch beyond the

pressure point in the direction of arrow :. The _ indicator lamp in the multifunction display lights up when it is dark and the light sensor activates the low- beam headlamps. 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.

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. Vehicles with static LED headlamps

The front and rear light clusters of your vehicle are equipped with LED light bulbs. Do not replace the bulbs yourself. Contact a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. 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.

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).

Overview of climate control systems Important safety notes Observe the settings recommended on the following pages. The windows could otherwise fog up. To prevent the windows from fogging up: Rswitch off climate control only briefly Rswitch on air-recirculation mode only

briefly

Rswitch on the cooling with air

dehumidification function

Rswitch on the defrost windshield function

briefly, if required

Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control can only be operated when the engine is running. Optimum operation is only achieved with the side windows and roof closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 154). i Ventilate the vehicle for a brief period

during warm weather, e.g. using the convenience opening feature (Y page 99). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly.
