Information about Service
Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval displayhas been inadvertently reset, this setting canbe corrected at a qualified specialist work-shop.
Have service work carried out as described inthe Maintenance Booklet. This may otherwiselead to increased wear and damage to themajor 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 can alsoobtain further information on maintenancework, for example.
Special service requirements
The specified maintenance interval takes onlythe normal operation of the vehicle intoaccount. Under arduous operating conditions orincreased load on the vehicle, maintenancework must be carried out more frequently, forexample:
Rregular city driving with frequent intermediatestops
Rif the vehicle is primarily used to travel shortdistances
Ruse in mountainous terrain or on poor roadsurfaces
Rif the engine is often left idling for long periods
Rin particularly dusty conditions, or if air-recir-culation mode is frequently used
In these or similar operating conditions, havethe interior filter, engine air cleaner, engine oiland oil filter, for example, changed more fre-quently. Under arduous operating conditions,the tires must be checked more often. Furtherinformation can be obtained at a qualified spe-cialist workshop, e.g. an authorized Mercedes-Benz Center.
Driving abroad
An extensive Mercedes-Benz Service network isalso available in other countries. You can obtainfurther information from any authorizedMercedes-Benz Center.
Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
!When cleaning your car, do not use:
Rdry, coarse or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces and films with hardobjects, e.g. rings or ice scrapers. Otherwise,you may scratch or damage the surfaces andfilms.
!Do not park your vehicle for a long period oftime directly after cleaning, particularly aftercleaning the wheel rim with wheel cleaner.Wheel cleaner can lead to the increased cor-rosion of the brake discs and pads. Therefore,drive for a few minutes after cleaning. Byheating up the brakes, the brake discs andpads dry. The vehicle can then be parked for along period of time.
Regular care of your vehicle is a condition forretaining the quality in the long term.
Use care products and cleaning agents recom-mended and approved by Mercedes-Benz.
Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING

Cleaning the exhaust pipes
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
!Do not clean the exhaust pipe with acid-based cleaning agents, such as bathroomcleaner or wheel cleaner.
!Mercedes-AMG vehicles with black exhaustpipes: the black-chrome tailpipe finishersshould not be polished with a chrome polish.They will otherwise lose their black sheen. Foroptimal care, the faceplates should be rubbedwith a lightly oiled cloth after every car wash.Commercially available engine and care oilsare suitable for this.
For heavier soiling, you can apply a fine paint-work polish with a microfiber cloth. Removethe excess polish residue after polishing.
Impurities combined with the effects of road gritand corrosive environmental factors may causeflash rust to form on the surface. You canrestore the original shine of the exhaust pipe bycleaning it regularly, especially in winter andafter washing.
XClean the exhaust pipe with a care producttested and approved by Mercedes-Benz.
Interior care
Cleaning the display
!For cleaning, do not use any of the following:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household cleaningagents
These may damage the display surface. Donot put pressure on the display surface whencleaning. This could lead to irreparable dam-age to the display.
XBefore cleaning the display, make sure that itis switched off and has cooled down.
XClean the display surface using a commer-cially available microfiber cloth and TFT/LCDdisplay cleaner.
XDry the display surface using a dry microfibercloth.
Cleaning the plastic trim
GWARNING
Care products and cleaning agents containing
solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag deploy-
ment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
!Never attach the following to plastic surfa-ces:
Rstickers
Rfilms
Rperfume oil container or similar
You could otherwise damage the plastic.

Maintenance and care

Tire-mounting tools should not be used nearthe valve. This could damage the electroniccomponents.
Only have tires changed at a qualified spe-cialist workshop.
Observe the instructions and safety notes in the"Changing a wheel" section (Ypage 310).
The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tires inthe center.
On vehicles that have the same size front andrear wheels, you can rotate the wheels accord-ing to the intervals in the tire manufacturer'swarranty book in your vehicle documents. If nowarranty book is available, the tires should berotated every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the directionof wheel rotation.
Clean the contact surfaces of the wheel and thebrake disc thoroughly every time a wheel is rota-ted. Check the tire pressure and, if necessary,restart the tire pressure loss warning system(Canada only) or the tire pressure monitor (USAonly).
Direction of rotation
Tires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk of hydro-planing. These advantages can only be gained ifthe tires are installed corresponding to thedirection of rotation.
An arrow on the sidewall of the tire indicates itscorrect direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.
