This chapter contains information on the following subjects:

Vehicles running on CNG (compressed natural gas) » page 123.
The correct grades of fuel for your vehicle are listed on a sticker affixed to the in-
side of the fuel filler flap » Fig. 99 on page 122.
WARNINGThe national legal requirements must be observed if carrying a spare canister
in the vehicle. We do not recommend carrying any fuel canisters in your vehi-
cle for safety reasons. in the event of an accident, these canisters can become
damaged and fuel may escape – risk of fire!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring, which can result in considerable damage to parts of the en-
gine and the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork – risk
of paint damage!
■
If the vehicle was not purchased in the country where it was intended to be op-
erated, you should check whether the fuel specified by the manufacturer is of-
fered in the country where the vehicle will be operated. You should also perhaps
check whether the manufacturer has recommended a different fuel for operation
of the vehicle in the corresponding country. Is this not the case, then you must
check whether it is permitted by the manufacturer to operate the vehicle with an-
other fuel type.
RefuellingFig. 99
Fuel filler
First read and observe the introductory information and safety warn- ings on page 122.
Open fuel filler flap
›
Open the fuel filler flap with one hand.
›
Hold the fuel filler cap on the fuel filler tube with one hand and unlock it by moving it to the left with the vehicle key.
›
Unscrew the filler cap by turning it to the left and place the cap onto the top of
the fuel filler flap » Fig. 99.
Closing the filler cap
›
Turn the filler cap to the right until it clicks into place.
›
Hold the fuel filler cap on the fuel filler tube with one hand and lock it by turn- ing the vehicle key to the right and remove the key.
›
Close the filler cap.
CAUTION
The fuel tank is full just as soon as the pump nozzle switches off for the firsttime, provided the nozzle has been operated properly. Do not continue filling the
fuel tank otherwise the expansion volume is filled up.
Note
The fuel tank has a capacity of about 35 litres
, containing a reserve of approx.
4 litres .
122General Maintenance
Safe natural gasFirst read and observe the introductory information and safety warn-ings
on page 123.
The safety concept of the natural gas system ensures safe operation. It is equip-
ped with the following security features.
› At each natural gas tank, there is a solenoid valve that closes automatically af-
ter turning off the ignition or when running in petrol mode.
› A thermal fuse prevents uncontrolled rise in pressure in the natural gas tank in
case of fire.
› A flow limiter prevents sudden emptying of the natural gas tank in case the
pressure system is damaged.
› All the attachment points and materials are designed for maximum safety.
Natural gas quality and consumption
First read and observe the introductory information and safety warn-ings
on page 123.
Natural gas is divided into quality groups H-gas and L-gas. The two types of gas
are subdivided according to their calorific value and nitrogen and carbon dioxide
contents. H-gas has a higher calorific value and lower nitrogen or carbon dioxide
content than L-gas.
The higher the calorific value of natural gas, the lower is the consumption. How-
ever, the calorific value and the nitrogen and carbon dioxide contents can vary
within a quality group. Therefore, the consumption of the vehicle may even vary
when driving with only one natural gas quality (either only H-gas or L-gas).
The engine control of your vehicle automatically adjusts to the different natural
gas qualities. Therefore both natural gas qualities can be mixed in the fuel tank. It is therefore not necessary to run the natural gas tank completely empty to fill up
another quality.

Position of the CNG label
First read and observe the introductory information and safety warn-
ings on page 123.
In some countries, national legislation requires that vehicles with CNG operation
be identified by one of the listed labels » Fig. 101.

126General Maintenance
WARNING■It is prohibited to work with naked flames or lights.■It is prohibited to smoke or carry out any activities that produce sparks.■
Never use a damaged vehicle battery – risk of explosion!
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!
■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of ex-
plosion and chemical burns.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive gas
mixture is also produced. An explosion can be caused through sparkling over during unclamping or loosening of the cable plug while the ignition is on.■
Creating a bridge between the poles on the battery (e.g. with a metal object
or cable) creates a short circuit - risk of melting the lead bars, and risk of ex-
plosion, battery fire and acid splashes.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the engine,
the ignition and all of the electrical components and disconnect the negative
terminal ( ) of the battery.
CAUTION
Improper handling of the battery can lead to damage. We recommend having all
work on the vehicle battery carried out by a specialist garage.
CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the vehicle first disconnect the nega- tive terminal ( ) and only then the positive terminal ( ) of the battery.■
When connecting the battery to the electrical system, connect the positive ter-
minal ( ) first and then the negative terminal ( ) of the battery. Under no circum-
stances must the battery cables be connected incorrectly – risk of a cable fire.
■
Ensure that battery acid does not come into contact with the bodywork – risk of
damage to the paintwork.
■ Do not place the battery in direct daylight in order to protect the vehicle battery
housing from the effects of ultra-violet light.■
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e. g.
control units) also in idle state. The battery discharge can be prevented by discon-
necting the negative terminal ( ) of the battery or by ensuring the battery is con-
tinuously charged with very low charging current.
■
If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge.
For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations.
Note
You should replace batteries older than 5 years.
Checking the battery electrolyte level
Fig. 110
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 134.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 110 , the electrolyte level can be determined by looking at the
change in colour.
