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 affected bycorrosion and damage caused by inadequatecare cannot always be completely repaired. Insuch cases, visit a qualified specialist workshop.
XRemove dirt immediately, where possible,while avoiding rubbing too hard.
XSoak insect remains with insect remover andrinse off the treated areas afterwards.
XSoak bird droppings with water and rinse offthe treated areas afterwards.
XRemove tree resin, oils, fuels and greases byrubbing gently with a cloth soaked in petro-leum ether or lighter fluid
XRemove coolant and brake fluid with a moistcloth and clear water.
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 recommen-ded and approved by Mercedes-Benz. This is thecase approximately every three to five months,depending on the climate conditions and thecare product used.
If dirt has penetrated the paint surface or if thepaint has become dull, the paint cleaner recom-mended and approved by Mercedes-Benzshould be used.
Do not use these care products in the sun or onthe hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MB Touch-Up Stick, to repair slight damage to the paint-work 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 matt effect:
RRubbing hard with unsuitable agents
RWashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polishingproducts, or gloss preserver, e.g. wax, for thepurpose of paintwork care. These productsare only suitable for high-gloss surfaces. Theiruse on vehicles with matte paintwork leads toconsiderable surface damage or, more spe-cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at aqualified 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 damageto the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels witha clear matte finish.
Use only insect remover and car shampoo fromthe range of care products approved byMercedes-Benz.
Cleaning the decorative film
!The following may have an effect on the ser-vice 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 matt dec-orative film. Polishing surfaces covered withfilm 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 care andtreatment of matte paintwork (Ypage 267),these notes also apply to matte decorative film.

Uniform Tire Quality Grading Standards
A uniform standard to grade the quality of tireswith regards to tread quality, tire traction andtemperature characteristics. The quality grad-ing assessment is made by the manufacturerfollowing specifications from the U.S. govern-ment. The ratings are molded into the sidewall ofthe tire.
Recommended tire pressures
The recommended tire pressure applies to thetires mounted at the factory.
The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires on a fully loaded vehicle and for the maxi-mum permissible vehicle speed.
The tire pressure table contains the recommen-ded pressures for cold tires for various operat-ing conditions, i.e. differing load and speed con-ditions.
Increased vehicle weight due to optional
equipment
The combined weight of all standard andoptional equipment available for the vehicle,regardless of whether it is actually installed onthe vehicle or not.
Rim
This is the part of the wheel on which the tire ismounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weightrating. The actual load on an axle must neverexceed the gross axle weight rating. The grossaxle weight rating can be found on the vehicleidentification plate on the B-pillar on the driver'sside.
Speed rating
The speed rating is part of the tire identification.It specifies the speed range for which the tire isapproved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight ofthe vehicle including fuel, tools, the spare wheel,accessories installed, occupants, luggage andthe drawbar noseweight, if applicable. The grossvehicle weight must not exceed the gross vehi-cle weight rating GVWR as specified on the vehi-cle identification plate on the B-pillar on thedriver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight of thevehicle including all accessories, occupants,fuel, luggage and the drawbar noseweight, ifapplicable). The gross vehicle weight rating isspecified on the vehicle identification plate onthe B-pillar on the driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optionalequipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressure isbar. 100 kilopascals (kPa) are the equivalent of1 bar.
Load index
In addition to the load-bearing index, the loadindex may also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capacitymore precisely.
Curb weight
The weight of a vehicle with standard equipmentincluding the maximum capacity of fuel, oil andcoolant. It also includes the air-conditioning sys-tem and optional equipment if these are instal-led in the vehicle, but does not include passen-gers or luggage.
Maximum load rating
The maximum tire load is the maximum permis-sible weight in kilograms or lbs for which a tire isapproved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated bydividing the maximum axle load of one axle bytwo.

Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Only add coolant that has been premixedwith the desired antifreeze protection. Youcould otherwise damage the engine.
You can find additional notes on the coolant inthe following places:
Rin the Mercedes-Benz Specifications forService Products, MB BeVo 310.1
-on the Internet athttp://bevo.mercedes-benz.com
-on the Mercedes-Benz BeVo app
Ra qualified specialized workshop
!Always use a suitable coolant mixture, evenin countries where high temperatures prevail.
Otherwise, the engine cooling system is notsufficiently protected from corrosion andoverheating.
iHave the coolant regularly replaced at aqualified specialist workshop and the replace-ment confirmed in the Maintenance Booklet.
Comply with the important safety notes for ser-vice products when handling coolant(Ypage 319).
The coolant is a mixture of water and corrosioninhibitor/antifreeze concentrate. It performsthe following tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to-35 ‡ (-37 †), the boiling point of the coolantduring operation is approximately 266 ‡(130 †).
The antifreeze concentrate/corrosion inhibitorconcentration in the engine cooling systemshould:
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 not bedissipated as effectively
Mercedes-Benz recommends a coolant or cor-rosion inhibitor/antifreeze concentrate inaccordance withMB Specifications for Service Products 310.1.
iWhen the vehicle is first delivered, it is filledwith a coolant mixture that ensures adequateantifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.

Important safety notes
GWARNING
Windshield washer concentrate could ignite if

nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
