Interior lighting control
General notes
In order to prevent the vehicle's battery fromdischarging, the interior lighting functions areautomatically deactivated after some time,unless the SmartKey is in positionHin theignition lock.
The color and brightness of the ambient light-ing are set via the multimedia system(Ypage 200).
Automatic interior lighting control
XTo switch on:set the switch to center posi-tionK.
XTo switch off:set the switch to the3position.
The interior lighting automatically switches onif you:
Runlock the vehicle
Ropen a door
Rremove the SmartKey from the ignition lock
The interior lighting is switched on for a settime when the SmartKey is removed from theignition lock. You can activate this delayedswitch-off using the on-board computer(Ypage 201).
Replacing bulbs
The front and rear lamps of your vehicle areequipped with LED bulbs. Do not replace thebulbs yourself. Contact a qualified specialistworkshop which has the necessary specialistknowledge and tools to carry out the workrequired.
Bulbs and lamps are an important aspect ofvehicle safety. You must therefore make surethat these function correctly at all times. Havethe headlamp setting checked regularly.
Windshield wipers
Switching the windshield wipers
on/off
!Do not operate the windshield wiperswhen the windshield is dry, as this could
damage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes place whenthe windshield is dry.
If it is necessary to switch on the windshieldwipers in dry weather conditions, always usewasher fluid when operating the windshieldwipers.
!If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluidafter washing the vehicle in an automaticcar wash.
!Intermittent wiping with rain sensor: dueto optical influences and the windshieldbecoming dirty in dry weather conditions,the windshield wipers may be activatedinadvertently. This could then damage thewindshield wiper blades or scratch the wind-shield.
For this reason, you should always switchoff the windshield wipers in dry weather.

Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Vehicles with decorative film: parts of yourvehicle are covered with decorative film.Maintain a distance of at least 27.5 in(70 cm) between the film-covered parts ofthe vehicle and the nozzle of the powerwasher.
Information about the correct distance isavailable from the equipment manufacturer.
Move the power washer nozzle around whencleaning your vehicle.
The water temperature of the power washermust not exceed 140 ‡ (60 †).
!Always maintain a distance of at least12 in (30 cm) between the vehicle and thepower washer nozzle. Information about thecorrect distance is available from the equip-ment manufacturer.
Move the power washer nozzle around whencleaning your vehicle.
Do not aim directly at any of the following:
RTires
RDoor gaps, roof gaps, joints, etc.
RElectrical components
RBattery
RPlug-type couplings
RLight bulbs
RSeals
RTrim elements
RVentilation slots
Damaged seals or electrical componentscan lead to leaks or failures.
!Vehicles with HANDS-FREE ACCESS: if aSmartKey with KEYLESS-GO is within thedetection range of the KEYLESS-GOantenna, the following situations could leadto the unintentional opening of the trunk lid:
Rusing a car wash
Rusing a power washer
Make sure that the SmartKey is at least6.5 ft (2 m) away from the vehicle.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwisedamage the paintwork.
Scratches, corrosive deposits, areas affectedby corrosion and damage caused by inade-quate care cannot always be completelyrepaired. In such cases, visit a qualified spe-cialist workshop.

272Care
Maintenance and care

The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It is responsible forthe following:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection downto -35 ‡ (-37 †), the boiling point of the cool-ant during operation is approximately 266 ‡(130 †).
The antifreeze/corrosion inhibitor concentra-tion in the engine cooling system should:
Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection downto -49 ‡ [-45 †]). Otherwise, heat will notbe dissipated as effectively.
If the vehicle has lost coolant, add equalamounts of water and antifreeze/corrosioninhibitor.
Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accordancewith MB Specifications for Service Products310.1.
iWhen the vehicle is first delivered, it is fil-led with a coolant mixture that ensures ade-quate antifreeze and anti-corrosion protec-tion.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.

Important safety notes
GWARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
!Only use washer fluid which is suitable forlamp lenses, e.g. MB SummerFit or MB Win-terFit. Unsuitable washer fluid may damagethe lamp lenses of the headlamps.
!Only MB SummerFit and MB WinterFitwasher fluid should be mixed together. Thespray nozzles may otherwise becomeblocked.
Do not use distilled or de-ionized water. Other-wise, the level sensor may give a false reading.
When handling washer fluid, observe theimportant safety notes on service products(Ypage 321).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixtureof water and windshield washer fluid, e.g.MB SummerFit.
XAdd 1 part MB SummerFit to 100 partswater.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixtureof water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to theinformation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-merFit or MB WinterFit, to the washer fluidall year round.
