The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. The cornering light function can only be activated when the low-beam headlamps are switched on.
Active:
Rif you are driving at speeds below 25 mph (40 km/h) and switch on the turn signals or turn the steering wheel
Rif you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h) and turn the steering wheel
Not active: if you are driving at speeds above 25 mph (40 km/h) or switch off the turn signals or turn the steering wheel to the straight-ahead position.
The cornering light function may remain lit for a short time, but is automatically switched off after no more than three minutes.
Adaptive Highbeam Assist
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.
X To activate: activate the Adaptive
Highbeam Assist function using the on- board computer (Y page 388). X Turn the light switch to c.
X Press the combination switch beyond the pressure point in the direction of arrow : (Y page 283). If it is dark and the light sensor activates the low-beam headlamps, the _ indicator lamp in the instrument cluster lights up.
If you drive at speeds above approximately 28 mph (45 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 35 mph (55 km/h) and no other road users have been detected:
Interior lighting 285
the high-beam headlamps are switched on automatically. The K indicator lamp in the instrument cluster also lights up.
If you drive at speeds below approximately 30 mph (45 km/h) or if other road users are identified or if the roads are sufficiently illuminated:
the high-beam headlamps are switched off automatically. The K indicator lamp in the instrument cluster goes out. The _ indicator lamp in the instrument cluster stays on.
X To deactivate: move the combination
switch back to its normal position. The _ indicator lamp in the instrument cluster goes out.
G WARNING The Adaptive Highbeam Assist is only an aid intended to support you while driving. The driver is and remains responsible for proper vehicle lighting in accordance with the prevailing light, sight and traffic conditions.
The system may be impaired or unavailable when
Rvisibility is poor, e.g. due to snow, rain, fog,
or heavy spray
Rthe optical sensor area of the windshield is dirty, fogged up, or covered by a sticker for example
The system cannot recognize the following road users:
RRoad users without a lighting system of
their own, e.g. pedestrians
RRoad users with dim lighting of their own,
e.g. cyclists
RRoad users whose lighting is obstructed,
e.g. road users behind a guardrail
RIn some seldom cases, even road users with
a lighting system of their own may be recognized too late or not at all.
The automatic high-beam headlamps will then not be deactivated or it will be activated in spite of preceding or oncoming road users.
This could endanger you and/or others and cause an accident. Always pay close attention to the traffic situation and switch off the high beam manually if necessary.
Headlamps fogged up on the inside
The headlamps may fog up on the inside if there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depending on the length of the journey and the weather conditions (humidity and temperature).
If the level of moisture does not diminish:
X Have the headlamps checked at a qualified
specialist workshop.

Important safety notes
Xenon bulbs
G DANGER 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 the Xenon bulbs yourself, but have them replaced at a qualified workshop.
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.
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
There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 287). 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.
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.
G WARNING Bulbs and lamps can become very hot. For this reason, allow them to cool down before changing them. Otherwise, you could burn yourself when you touch them.
Keep bulbs out of the reach of children. Otherwise, they could, for example, damage the bulbs and injure themselves.
Never use a bulb which has been dropped. Such a bulb may explode and injure you.
Halogen bulbs are pressurized and could explode when you change them, especially if they are very hot. You should therefore wear eye protection and gloves when you are changing them.

You can also set some automatic climate control functions via COMAND (Y page 269).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the convenience opening feature (Y page 96). 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 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 blower may be
activated automatically 40 minutes after the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the air-conditioning system.
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 Please read the information on qualified
specialist workshops (Y page 31).
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 blocked filter replaced at a Mercedes- Benz Center as soon as possible.
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.
Automatic climate control controls the temperature and the humidity in the vehicle interior and filters undesirable substances from the air.
Automatic climate control is only operational when the engine is running16. Optimum operation is only achieved if you drive with the side windows and sliding sunroof/panorama roof with power tilt/sliding panel closed.

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 intake grille on the hood free of blockages, such as ice, snow or leaves
Rnever cover the air vents or air intake grille
in the vehicle interior.
i For virtually draft-free ventilation, adjust
the sliders of the air vents to the center position.

Setting the glove box air vent
When automatic climate control is activated, the glove box can be ventilated, for instance to cool its contents. The level of airflow depends on the airflow and air distribution settings.
! Close the air vent when heating the
vehicle.
At high outside temperatures, open the air vent and activate the "cooling with air dehumidification" function. Otherwise, temperature-sensitive items stored in the glove box could be damaged.

Breaking-in notes
The first 1,000miles (1,500 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 1,000miles (1,500km).
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.
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, for the first 1,000miles
(1,500km), drive in drive program E (in AMG vehicles in drive program C).
After 1,000 miles (1,500km), you can increase the engine speed gradually and bring the vehicle up to full speed.

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.
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 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.
G WARNING HYBRID vehicles: It is imperative that you read the HYBRID Supplemental Operating Instructions included in your vehicle literature portfolio. You may otherwise not receive all necessary safety information and warning for the operation of your vehicle.
! 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.
! S 63 AMG: 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.

General information
Vehicles with KEYLESS-GO are equipped with a SmartKey featuring an integrated KEYLESS- GO function and a detachable Start/Stop button.
The Start/Stop button must be inserted into the ignition lock and the SmartKey must be in the vehicle.
Pressing the Start/Stop button several times in succession corresponds to the different SmartKey positions in the ignition lock. This is only the case if you are not depressing the brake pedal.
If you depress the brake pedal and press the Start/Stop button, the engine starts immediately.
The Start/Stop button can be removed from the ignition lock. Then, you can insert the SmartKey into the ignition lock.
