!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 of the vehicleand the nozzle of the power washer.
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 †).
!If the SmartKey is within the rear detectionrange of KEYLESS-GO, the following situa-tions, for example, could lead to the uninten-tional opening of the tailgate:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least 10 ft(3 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 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.
When water no longer forms beads on the paintsurface, use the care product Paint Care, whichhas been approved for Mercedes-Benz. This isthe case approximately every three to fivemonths, depending on the climate conditionsand the care product used.
The cleaning product Paint Cleaner, which hasbeen recommended and approved forMercedes-Benz, should be used when dirt haspenetrated the paint surface.
Also use Paint Cleaner on paint that has becomedull.
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 approved Mercedes-Benz careproducts.

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.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire widthin percent.
Tire pressure
This is pressure inside the tire applying an out-ward force to each square inch of the tire's sur-face. The tire pressure is specified in pounds persquare inch (psi), in kilopascal (kPa) or in bar.The tire pressure should only be corrected whenthe tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursand
Rif the vehicle has not been driven further than1 mile (1.6 km)
Tread
The part of the tire that comes into contact withthe road.
Bead
The tire bead ensures that the tire sits securelyon the wheel. There are several steel wires in thebead to prevent the tire from coming loose fromthe wheel rim.
Sidewall
The part of the tire between the tread and thebead.

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the impor-tant safety notes on service products(Ypage 358).
The brake fluid change intervals can be found inthe Maintenance Booklet.
Only use brake fluid approved by Mercedes-Benz in accordance with MB-Freigabe or MB-Approval 331.0.
Information on approved brake fluid can beobtained in the following places:
Rfrom an authorized Mercedes-Benz Center

-on the Internet athttp://bevo.mercedes-benz.com
-on the Mercedes-Benz BeVo app
iHave the brake fluid regularly replaced at aqualified specialist workshop in accordancewith the replacement intervals and thereplacement confirmed in the MaintenanceBooklet.
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

Comply with the important safety notes for ser-vice products when handling coolant(Ypage 358).
The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs the fol-lowing 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 an antifreeze/corrosion inhibitor concentrate in accordancewith MB Specifications for Service Products310.1.
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.
