Flow improver
To improve the low-temperature resistance of diesel fuel, a flow improver can be attached. The effectiveness of a flow improver is not guaranteed for every fuel.
Only use flow improvers tested and approved by Mercedes-Benz. During use, please observe the information on operation.
Correct dosage and sufficient mixing are decisive in improving low-temperature resistance with the flow improver. Overdosage can potentially even decrease low-temperature resistance and must therefore be avoided. Follow the manufacturer's guidelines on dosage.
Mix the additive into the diesel in good time, before the flow characteristics of the diesel become insufficient. Otherwise, malfunctions can arise through heating the fuel system, e.g. through parking in a heated garage.
More information about recommended flow improvers can be obtained from any qualified specialist workshop.

General notes
! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment.
Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment.
Comply with the important safety notes for service products when handling engine oil (Y page 439).
The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems.
For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center. Or visit the website http://bevo.mercedes-benz.com.
The table shows which engine oils have been approved for your vehicle.
DEF freezes at a temperature of approximately 12 ‡ (-11 †). The vehicle is delivered from the factory equipped with a DEF preheating system. Winter operation can thus be guaranteed even at temperatures below 12 ‡ (-11 †).
Additives
! Only use DEF in accordance with ISO
22241. Do not use additives with DEF and do not dilute DEF with water. This may destroy the BlueTEC exhaust gas aftertreatment system.
Purity
! Impurities in DEF (e.g. due to other
service products, cleaning agents or dust) lead to:
Rincreased emission values
Rdamage to the catalytic converter
Rengine damage
Rmalfunctions in the BlueTEC exhaust gas
aftertreatment system
Assuring the purity of DEF is particularly important with respect to avoiding malfunctions in the BlueTEC exhaust gas aftertreatment system.
If DEF is pumped out of the DEF tank, e.g. during repair work, it must not be returned to the tank. The purity of the fluid can no longer be guaranteed.

Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin.
Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside temperatures. The table shows you which SAE classifications are to be used. The low- temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification.
Brake fluid
G WARNING 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.
Comply with the important safety notes for service products when handling brake fluid (Y page 439).
The brake fluid change intervals can be found in the Maintenance Booklet.

The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant during operation is approximately 266 ‡ (130 †).
The antifreeze/corrosion inhibitor concentration in the engine cooling system should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat will not be dissipated as effectively.
If the vehicle has lost coolant, add equal amounts of water and antifreeze/corrosion inhibitor.
Mercedes-Benz recommends an antifreeze/ corrosion inhibitor concentrate in accordance with MB Specifications for Service Products 310.1.
The coolant is checked with every maintenance interval at a qualified specialist workshop.
i When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection.
Only use brake fluid approved by Mercedes- Benz according to MB Approval 331.0.
Information about approved brake fluid can be obtained at any qualified specialist workshop or on the Internet at http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop and have this confirmed in the Maintenance Booklet.
Coolant
Important safety notes
G WARNING 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 premixed with the desired antifreeze protection. You could otherwise damage the engine.
Further information on coolants can be found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop.
