coolant MERCEDES-BENZ SLC 2019 User Guide

Rim
This is the part of the wheel on which the tireis mounted.
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 driv-er's side.
Speed rating
The speed rating is part of the tire identifica-tion. It specifies the speed range for which thetire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weightof the vehicle including fuel, tools, the sparewheel, accessories installed, occupants, lug-gage and the drawbar noseweight, if applica-ble. The gross vehicle weight must not exceedthe gross vehicle weight rating GVWR as speci-fied on the vehicle identification plate on theB-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight ofthe vehicle including all accessories, occu-pants, fuel, luggage and the drawbar nose-weight, if applicable). The gross vehicle weightrating is specified on the vehicle identificationplate on the 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 pressureis bar. 100 kilopascals (kPa) are the equivalentof 1 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 capa-city more precisely.
Curb weight
The weight of a vehicle with standard equip-ment including the maximum capacity of fuel,oil and coolant. It also includes the air-condi-tioning system and optional equipment if theseare installed in the vehicle, but does notinclude passengers or luggage.
Maximum load rating
The maximum load rating is the maximum per-missible weight in kilograms or lbs for which atire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for onetire.
Maximum load on one tire
Maximum load on one tire. This is calculatedby dividing the maximum axle load of one axleby two.
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'ssurface. The tire pressure is specified inpounds per square inch (psi), in kilopascal(kPa) or in bar. The tire pressure should onlybe corrected when the 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 furtherthan 1 mile (1.6 km)

Additives
!Do not use any additives in the engine oil.This could damage the engine.
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 298).
The brake fluid change intervals can be foundin the Maintenance Booklet.
Only use brake fluid approved by Mercedes-Benz in accordance with MB-Freigabe or MB-Approval 331.0.
Information about approved brake fluid can beobtained at any qualified specialist workshop
or on the Internet athttp://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at aqualified specialist workshop and thereplacement confirmed in the MaintenanceBooklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. 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 coolantin the 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,even in countries where high temperaturesprevail.
Otherwise, the engine cooling system is notsufficiently protected from corrosion andoverheating.
iHave the coolant regularly replaced at aqualified specialist workshop and thereplacement confirmed in the MaintenanceBooklet.
Comply with the important safety notes forservice products when handling coolant(Ypage 298).

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.

Windshield washer system
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 298).
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.
