Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval dis-play has been inadvertently reset, this set-ting can be corrected at a qualified special-ist workshop.
Have service work carried out as describedin the Maintenance Booklet. This may other-wise lead to increased wear and damage tothe major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-ized Mercedes-Benz Center, will reset theASSYST PLUS service interval display after theservice work has been carried out. You canalso obtain further information on mainte-nance work, for example.
Special service requirements
The specified maintenance interval takes onlythe normal operation of the vehicle intoaccount. Service work will need to be per-formed more often if the vehicle is operatedunder arduous conditions or increased loads.
The ASSYST PLUS service interval display isonly an aid. The driver of the vehicle is respon-sible for whether service work will need to beperformed more frequently than required as aresult of the actual operating conditionsand/or loads.
Examples of arduous operating conditions:
Rregular city driving with frequent intermedi-ate stops
Rthe vehicle is primarily used to travel shortdistances
Rfrequent use in mountainous terrain or onpoor road surfaces
Rthe engine is often left idling for long peri-ods
Rparticularly dusty conditions, or if air-recir-culation mode is frequently used
In these or similar operating conditions, havethe interior filter, air filter, engine oil and oil fil-ter, for example, changed more frequently.Under arduous operating conditions, the tiresmust be checked more often. Further informa-tion can be obtained at a qualified specialistworkshop.

Washing the vehicle and cleaning
the paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is
restored.
!When DISTRONIC PLUS or the HOLD func-tion is activated, the vehicle brakes auto-matically in certain situations.
To avoid damage to the vehicle, deactivateDISTRONIC PLUS and the HOLD function inthe following or similar situations:
Rwhen towing the vehicle
Rin the car wash
!It is preferable to use car washes withadjustable high-pressure pre-cleaning thatcorresponds to the specification for theCabriolet program. In car washes that usehigh water pressures, there is a risk that asmall amount of water may leak into thevehicle.
!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.
!Never clean your vehicle in a TouchlessAutomatic Car Wash as these use specialcleaning agents. These cleaning agents candamage the paintwork or plastic parts.
If you have your vehicle cleaned in a high-pressure automatic car wash, smallamounts of water may enter the vehicle.
!Make sure that the automatic transmissionis in positionNwhen washing your vehiclein a tow-through car wash. The vehicle couldbe damaged if the transmission is in anotherposition.
!Make sure that:
Rthe side windows and the roof are com-pletely closed
Rthe climate control blower is switched off
Rthe windshield wiper switch is at position0
The vehicle could otherwise be damaged.
You can clean the vehicle at an automatic carwash from the very start.
Preferably clean the vehicle at automatic carwashes that use textile washing elementswithout brushes. This prevents fine scratchesfrom forming on the paintwork and film.
If the vehicle is very dirty, pre-wash it beforecleaning it in an automatic car wash.
After using an automatic car wash, wipe offwax from the windshield and the wiper blades.This will prevent smears and reduce wipingnoises caused by residue on the windshield.
iVehicles with decorative film: select awash program without hot wax at the auto-matic car wash.
Washing by hand
In some countries, washing by hand is onlyallowed at specially equipped washing bays.
Care271
Maintenance and care
Z

XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
If water no longer forms "beads" on the paintsurface, use the paint care products recom-mended and approved by Mercedes-Benz. Thisis the case approximately every three to fivemonths, depending on the climate conditionsand the care product used.
If dirt has penetrated the paint surface or ifthe paint has become dull, the paint cleanerrecommended and approved by Mercedes-Benz should be used.
Do not use these care products in the sun oron the hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MBTouch-Up Stick, to repair slight damage tothe paintwork quickly and provisionally.
Matte finish care
!Never polish the vehicle or the light alloywheels. Polishing causes the finish to shine.
!The following can give the paint a glossyappearance and thus reduce the matteffect:
RRubbing hard with unsuitable agents
RWashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polish-ing products, or gloss preserver, e.g. wax,for the purpose of paintwork care. Theseproducts are only suitable for high-gloss sur-faces. Their use on vehicles with mattepaintwork leads to considerable surfacedamage or, more specifically, to shiny, spot-ted areas.
Always have paintwork repairs carried out ata qualified specialist workshop.
!Only use automatic car washes which cor-respond to the latest technological stand-ards. Never use wash programs which finishby treating the vehicle with hot wax.
Observe these notes if your vehicle has a clearmatte finish. This will help you to avoid dam-age to the paintwork due to incorrect treat-ment.
These notes also apply to light alloy wheelswith a clear matte finish.
iUse only insect remover and car shampoofrom the range of recommended andapproved Mercedes-Benz care products.
Cleaning the decorative film
!The following may have an effect on theservice life and color of decorative film:
Rsunlight
Rtemperature, e.g. hot-air fan
Rweather conditions
Rstone impacts and dirt
Rchemical cleaning agents
Rgreasy substances
!Do not use any types of polish on mattdecorative film. Polishing surfaces coveredwith film gives it a shiny finish.
!Do not treat matt or structured decorativefilm with wax. This may lead to marks thatcannot be removed.
Observe the notes in the section on the careand treatment of matte paintwork(Ypage 273); these notes also apply to mattedecorative film.
To clean, use plenty of water and a mild clean-ing agent without additional or abrasive prod-ucts, e.g. a car shampoo approved byMercedes-Benz.
XDry vehicles covered with film using a soft,absorbent cloth after every wash.Water marks could otherwise form.
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.
XRemove dirt immediately, where possible,while avoiding rubbing too hard.The decorative film may be irreparably dam-aged.
XSoak insect remains with insect removerand rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse offthe treated areas afterwards.
The cleaning product, Paint Cleaner, which hasbeen approved and recommended byMercedes-Benz, should be used when dirt haspenetrated the decorative film surface or thedecorative film has become dull.
