Fuel

Caution

Fuel should contain detergent

additives that help prevent engine

and fuel system deposits from

forming. Clean fuel injectors and

intake valves will allow the emission

control system to work properly. In

certain countries fuel does not

contain sufficient quantities of

additive to keep fuel injectors and

intake valves clean. In these

countries a fuel additive is required for

some engines to make up for this lack

of detergency. Only use fuel additive

approved for the vehicle.

Fuel for petrol engines

Do not use fuel or fuel additives

that contain metallic compounds

such as manganese-based

additives. This may cause engine

damage.

Caution

Only use unleaded fuel that complies

with European standard EN 228 or

equivalent.

The engine is capable of running with

fuel that contains up to 10% ethanol

(e.g. named E10).

Use of fuel that does not comply to

EN 228 or equivalent can lead to

deposits or engine damage.

Caution

Adding fuel additive to the filled fuel

tank is required at least every

Use of fuel with a lower octane

rating than the lowest possible

Prohibited fuels

The engine specific requirements

regarding octane rating are given in

the engine data overview 3 284. A

country-specific label at the fuel filler

flap can supersede the requirement.

Fuels containing oxygenates such as

ethers and ethanol, as well as

reformulated fuel, are available in

some cities. If these fuels comply with

the previously described

specification, then they are

acceptable to use. However, E85

(85% ethanol) and other fuels

containing more than 15% ethanol

must be used only in FlexFuel

vehicles.

Fuel for diesel engines

Use of fuel that does not comply to

EN 590 or similar can lead to

engine powerloss, increased wear

or engine damage and may affect

your warranty.

Caution

Do not use fuel containing

methanol. It can corrode metal

parts in the fuel system and also

damage plastic and rubber parts.

This damage would not be

Only use diesel fuel that complies

with EN 590 and which has a sulphur

concentration of max. 10 ppm.

Fuels with a biodiesel (compliant with

EN 14214) content of max. 7% by

volume may be used (e.g. named

B7).

If travelling in countries outside the

European Union occasional use of

Euro-Diesel fuel with a sulphur

concentration below 50 ppm is

possible.

Do not use marine diesel oils, heating

oils, Aquazole and similar diesel-

water emulsions. Diesel fuels must

covered by the vehicle warranty.

Some fuels, mainly high octane

racing fuels, can contain an octane

enhancing additive called

methylcyclopentadienyl manganese

tricarbonyl (MMT). Do not use fuels or

fuel additives with MMT as they can

Low temperature operation

diesel products with biodiesel blends

may clog, freeze or gel, which may

affect the fuel supply system. Starting

and may cause engine stalling, poor

starting or damage on the fuel

injection system.

9 Danger

Fuel is flammable and explosive.

No smoking. No naked flames or

sparks.

Refuelling

If you can smell fuel in your

vehicle, have the cause of this

remedied immediately by a

workshop.

A label with symbols at the fuel filler

flap is indicating the allowed fuel

types. In Europe the pump nozzles of

the filling stations are marked with

these symbols. Refuel only the

allowed fuel type.

The fuel filler flap can only be opened

if the vehicle is unlocked. Release the

fuel filler flap by pushing the flap.

Petrol and Diesel refuelling

Caution

9 Danger

In case of misfuelling, do not

switch on ignition.

Before refuelling, switch off

ignition and any external heaters

with combustion chambers.

Follow the operating and safety

instructions of the filling station

when refuelling.

Fuel filler flap is located at right rear

side of vehicle.

Driving and operating

223

Place the nozzle in straight position to

the filler neck and press with slight

force to insert.

To refuel, switch on pump nozzle.

After the automatic cut-off, the tank

can be topped up by operating the

pump nozzle a maximum of two more

times.

Caution

Wipe off any overflowing fuel

immediately.

The misfuel inhibitor ensures that the

flap of the fuel filler neck can only be

opened by using the suitable fuel

nozzle or a funnel for emergency

refilling.

In case of an emergency, refill with a

canister. A funnel must be used to

open the cap of the filler neck.

The funnel may be stowed in the load

compartment or the glovebox.

Place the funnel in straight position to

the filler neck and press with slight

force to insert.

After topping-up, clean funnel from

fuel remains and stow it away.

Close the flap and allow it to engage.

Misfuel inhibitor

9 Warning

Do not try to open the flap of the

fuel filler neck manually on

vehicles with misfuel inhibitor.

Disregarding this could lead to

trapping of the fingers.
