Vehicles running on petrol
The fuel gauge » Fig. 4 only operates if the ignition is switched on.
The fuel tank has a capacity of about 35 litres. If the fuel gauge in the fuel tank
reaches the reserve capacity level, the warning symbol of on » Fig. 4 - will
appear in the instrument cluster or the symbol will flash for 10 seconds togeth-
er with the remaining segments in the instrument cluster display » Fig. 4 - .
There are now about 4 litres of fuel remaining in the tank.
An audible signal sounds as a warning signal.
Vehicles running on CNG (compressed natural gas)
The fuel gauge » Fig. 5 only operates if the ignition is switched on.
When the vehicle runs on petrol, the pointer of the fuel gauge is in the range

CAUTION
Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring. This can result in considerable damage to parts of the engine

Current fuel consumption
The current fuel consumption level is displayed in litres/100 km 1)
. You can use this
information to adapt your driving style to the desired fuel consumption.
The display appears in litres/hour if the vehicle is stationary or driving at a low
speed 2)
.
Average fuel consumption
The average fuel consumption since the memory was last erased is displayed in
litres/100 km 1 )
.
If you wish to determine the average fuel consumption over a certain period of
time, you must set the memory at the start of the new measurement to zero » page 13 . After erasing the memory, no value is displayed until you have
driven approx. 300 m.
The display is updated regularly while you are driving.
Range
The estimated range is displayed in kilometres. It indicates the distance you can still drive with your vehicle based on the level of fuel in the tank and the same
style of driving.
The display is shown in steps of 10 km. After lighting up of the warning light for
the fuel reserve the display is shown in steps of 5 km.
The fuel consumption over the last 50 km is used to calculate the information.The range will increase if you drive in a more economical manner.
Distance travelled
The distance travelled since the memory was last erased is displayed » page 13. If
you want to measure the distance travelled from a particular moment in time, re-
set the memory to zero at that moment in time » page 13.
The maximum distance indicated in both memories is 1 999 km. The indicator is
set back to zero if this period is exceeded.
Average speed
The average speed since the memory was last erased is displayed in km/hour . To determine the average speed over a certain period of time, set the memory to
zero at the start of the measurement » page 13.After erasing this data, no value appears in the display until you have driven ap-
prox. 300 m.

Introduction
This chapter contains information on the following subjects:
Refuelling
122
Unleaded petrol
123
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
In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops.WARNING■ Stop the engine before refuelling.■Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!■
When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling.
■
Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries.
Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling).■
Noises that occur during refuelling represent no risk.
■
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi- cate exactly the same level as was the case immediately after refuelling when theengine is restarted. This is not due to any system leakages but a drop in pressurein the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling.
■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why the petrol tank runs empty faster than the natural gas tank.
■
The capacity of the natural gas tank is about 11 kg, of which about 1.5 kg are a
reserve.
■
The capacity of the petrol tank is about 10 l, of which about 5 l are a reserve.
Automatic switching from CNG to petrol mode
First read and observe the introductory information and safety warn-
ings
on page 123.
The vehicle automatically switches over from CNG mode to petrol mode when the following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas.
Natural gas as fuel
First read and observe the introductory information and safety warn-ings
on page 123.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts.
Regular gas system checks
First read and observe the introductory information and safety warn-ings
on page 123.
Every two years, the following inspections must be carried out:
› Check the condition of the fuel filler cap, filler neck and sealing ring, and clean
sealing ring if necessary.
› Check gas system for leaks.
The following checks must be carried out every four years: › Check gas tank mounting for secure attachment and possible damage.
The gas tank must be filled prior to the regular gas system check.
