Checking and refilling levels
220Checking and refilling levelsRefuellingThe tank flap is released manually. The tank holds approxi-
mately 70 litres.The flap that covers the tank cap is unlocked and locked automati-
cally by the central locking.
Unscrewing the tank cap
– Press the right side of the flap to open it.
– Unscrew the fuel tank cap anti-clockwise.
– Hook the cap onto the support fitted to the open tank flap
⇒fig. 163 . Closing the tank cap
– Screw the tank cap clockwise into the filler opening until it you
hear it click into position.
– Close the tank flap.
The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are warm.
T he co rr ec t fu el g rad e fo r you r v eh icle is giv en on a sti cker o n th e i nsid e of the
fuel tank flap. Here you will find further information on fuel.
WARNING
•Fuel is highly flammable and can cause serious burns and other inju-
ries.
−Never smoke or use an open flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion hazard.
− Follow legal requirements for the use of spare fuel canisters.
− For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident
and leak.•If, in exceptional circumstances, you have to carry a spare fuel canister,
please observe the following points:
−Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This could cause an explosion. Always place the canister on the
ground to fill it.

tion. The damage caused by the use of these antifreezes may lead to a loss of
coolant fluid, causing serious damage to the engine.
•G12++ antifreeze can be mixed only with antifreeze additives G11, G12
and G12+.Checking the coolant level
The coolant level can be checked visually.– Switch the ignition off.
– Check the coolant level on coolant fluid expansion tank ⇒fig. 168 . When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the corresponding general overview of the engine
compartment. The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp on the instrument panel
display
⇒page 78. However, we recommend that it should be checked occa-
sionally.
Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a qualified workshop
without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid can only occur if the
coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the coolant fluid. Such additives
could seriously impair the function of the cooling system.To p p i n g u p t h e c o o l a n t f l u i d
Be careful when topping up with coolant fluid.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 168 with a cloth, and
carefully unscrew the cap anti-clockwise ⇒.
– Add coolant fluid.
– Screw on the cap tightly.

The tyre mobility system is stor ed under the floor panel in the
luggage compartment.– Take hold of the handle and fold back the floor panel in the
luggage compartment.
– Take out the tyre mobility system.Your vehicle is equipped with a Tyre Mobility System in case of a puncture.
The tyre mobility system consists of a container with sealing compound and
a compressor to generate the required tyre pressure.
Instructions for using the sealant compound and the compressor are
included with the sealant can.
Spare steel rim wheel
The spare steel rim wheel is carried in the wheel well under
the floor panel in the luggage compartment. It is only
intended for temporary use over short distances.Taking out the spare wheel
–Turn the plastic knob ⇒fig. 178 anti-clockwise.
– Take out the spare wheel.
Securing the defective wheel in the spare wheel well
– Place wheel in spare wheel well in the luggage compartment.
– Secure the wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the tailgate.

Loosen the wheel bolts only about one turn before raising the vehicle with
the jack. Failure to do so could result in an accident.
Note
•Do not use the hexagonal socket in the screwdriver handle to loosen or
tighten the wheel bolts.•If the wheel bolt does not come loose, it may be possible to release it by
pushing down the end of the spanner carefully with your foot. Hold on to the
vehicle for support and take care not to slip.
