250Checking and refilling levels
For the sake of the environment
Do not overfill the fuel tank – it may cause the fuel to overflow if it becomes
warm.
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 
Refuelling natural gas

Before refuelling, the engine and the ignition, mobile telephone and heat-
ing must be switched off separately
⇒ .
Read the instructions on how to use the natural gas pump carefully.
The vehicle is not prepared for refuelling with liquefied natural gas (LNG)
⇒ 
. Before refuelling with natural gas, make sure to add the appropriate
type of fuel ⇒ page 246.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel tank cap, next to the petrol
filler mouth.
● Unlock the vehicle with the key or with the central locking button 
situ-
ated on the driver door ⇒ page 87.
● Press on the rear area of the flap and open it.
Refuelling
Thing to note: if the ambient temperature is very high, the natural gas pump
protection against overheating may disconnect this automatically.
● Remove the plug from the gas filler mouth ⇒ Fig. 152 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place. 

Checking and refilling levels
WARNING
Natural gas is a highly explosive, easily flammable substance. Incorrect
handling of the natural gas can cause accidents serious burns and other
injuries.
● Before refuelling with natural gas, engage the filler neck correctly. If
you smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.
Note
● The filling nozzles of all natural gas pumps might not be operated in the
same way. If you do not know, ask a qualified employee at the petrol station
to do the refuelling.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of damage to the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. Bonnet
Working on components in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
.
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place the lever in neutral; if it
has an automatic gearbox, place the selector lever in position P.
● Wait for the engine to cool down.
● Keep children away from the engine compartment.

subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table
on page 260). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered.

Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 251
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
