The warning lights show certain functions/faults and may be accompanied by
audible signals.
WARNING■ If illuminated warning lights and the corresponding descriptions and warn-
ing notes are not observed, this may result in severe injuries or major vehicle
damage.■
The engine compartment of your car is a hazardous area. There is a risk of
injuries, scalding, accidents and fire when working in the engine compart-
ment, e.g. inspecting and replenishing oil and other fluids. It is essential to ob-
serve safety notes » page 127, Engine compartment .

 Handbrake
First read and observe the introductory information and safety warn-
ings
on page 16.
The warning light 
comes on if the handbrake is applied. An audible warning is
also given if you drive the vehicle for at least 3 seconds at a speed of more than
6 km/h.

Braking system
First read and observe the introductory information and safety warn-ings
on page 16.
The warning light 
illuminates if the brake fluid level is too low or there is a
fault in the ABS.
Stop the vehicle, switch off the engine, and check the level of the brake flu-
id » page 133 .

16Using the system

NoteIf the vehicle's battery has been disconnected and reconnected, the warning light comes on after switching on the ignition. The warning light should go out after
driving a short distance.
 Traction Control System (TC)
First read and observe the introductory information and safety warn-ings
on page 16.
The warning light 
comes on for a few seconds when the ignition is switched
on.
The warning light comes on when driving when a control cycle is activated. The warning light illuminates permanently if there is a fault in the TCS.
The fact that the TCS operates together with the ABS means that the TCS warn-ing light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the TCS
can be switched off for technical reasons. In this case, the TCS can be switched
on again by switching the ignition on and off. If the warning light goes out, the
TCS is fully functional again.
Further information » page 81, Traction Control System (TCS) .
Note
If the vehicle's battery has been disconnected and reconnected, the warning light
 comes on after switching on the ignition. The warning light should go out after
driving a short distance.
Antilock brake system (ABS)
First read and observe the introductory information and safety warn-ings
on page 16.
If the warning light 
lights up, there is a fault in the ABS.
The vehicle will only be braked by the normal brake system without the ABS. Seek help from a specialist garage.
Further information » page 81, Antilock Braking System (ABS) .WARNING■
If you have to stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warning
light system » page 36.■
If the warning light  » page 16 is displayed simultaneously with the ABS
warning light ,  do not continue your journey! Seek help from a specialist
garage.
■
The following guidelines should be observed when opening the bonnet and
checking the brake fluid level » page 127, Engine compartment .
■
A fault to the ABS system or the braking system can increase the vehicle's
braking distance – risk of accident!

 Exhaust inspection system
First read and observe the introductory information and safety warn-
ings

If the warning light 
lights up, there is a fault in the exhaust inspection system.
The engine control unit allows the vehicle to run in emergency mode.
Seek help from a specialist garage.

If the warning light 
lights up, there is a fault in the engine control. The engine

19warning lights and instruments

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.
