Airbag deployment
98WARNING■ An airbag can only offer you optimal protection in combination with a fas-
tened seat belt .■
The airbag is not a substitute for the seat belt, but instead forms part of the
complete passive vehicle safety concept.
■
To ensure passengers are protected with the greatest possible effect when
the airbag is deployed, the front seats must be correctly adjusted to match
the body size » page 91, Correct seated position .
■
If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, you are exposing yourself to increased risk
of injury in the event of an accident.
WARNINGObserve the following instructions for handling the airbag system.■If there is a fault, the airbag system must be checked by a specialist garage
immediately. Otherwise, there is a risk that the airbag will not be deployed in the event of an accident.■
No modifications of any kind must be made to parts of the airbag system.
■
Any work on the airbag system including the installation and removal of sys-
tem components due to other repair work (e.g. removal of the steering wheel)
must only be carried out by a specialist garage.
■
Never make any changes to the front bumper or bodywork.
■
It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.
■
The protective function of the airbag system is sufficient for only one acci-
dent. The airbag system must then be replaced if the airbag has been de-
ployed.

System description
First read and observe the introductory information and safety warn-ings
on page 98.
The functional status of the airbag system is indicated by the indicator light  in
the instrument cluster » page 20.
When the airbags are deployed, they fill with gas and inflate.
A grey white or red, non-harmful gas is released when the airbag is inflated. This
is perfectly normal and is not an indication of a fire in the vehicle.
Depending on the vehicle equipment, the airbag system consists of the
following modules.
› Electronic control unit.

Automatic car wash systems
First read and observe the introductory information and safety warn-
ings
on page 113.
The usual precautionary measures must be taken before washing the vehicle in
an automatic car wash system (e.g. closing the windows and the sliding/tilting
roof etc.).
If your vehicle is fitted with any particular attached parts, such as a spoiler, roof
rack system, two-way radio aerial etc., it is best to consult the operator of the car
wash system beforehand.
After an automatic wash with wax treatment, the lips of the wipers should be cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
WARNINGFold in the exterior mirrors to prevent damage before washing the vehicle in
an automatic car wash system.

Washing with a high-pressure cleaner
First read and observe the introductory information and safety warn-
ings
on page 113.
When washing the vehicle with a high-pressure cleaner, the instructions for use
of the equipment must be observed. This applies in particular to the pressure
used and to the spraying distance .
Maintain a sufficiently large distance to the parking aid sensors and soft materials
such as rubber hoses or insulation material.
WARNINGNever use circular spray nozzles or dirt cutters! 114General Maintenance

Unleaded petrolFirst read and observe the introductory information and safety warn-
ings
on page 122.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 1)
standard.
All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (E10).
Prescribed fuel – unleaded petrol min. 95 RON Use unleaded fuel with the octane rating 95 RON or higher.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if petrol with the octane rating 95 RON is not available »
.
Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION
■ Even filling the tank with leaded petrol that does not meet the standards once
can lead to serious damage to parts of the exhaust system!■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is used by mistake, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We recom-
mend that you have the fuel system cleaned by a specialist garage.CAUTION■ If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible.■
Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.
■
Even in the event of an emergency, petrol of a lower octane number than 91
RON must not be used, otherwise the engine can be severely damaged!
CAUTION
■ In no case may fuel additives with metal components be used, especially not
with manganese and iron content. LRP(lead replacement petrol) fuels with metal-
lic components may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system!■
Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or exhaust system!
Note
■ Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.

126WARNING■When operating a CNG-powered vehicle, the national legal requirements
must be observed.■
If a fault occurs or a leak in the natural gas system is suspected or if you
smell gas, proceed as follows: ■Stop immediately and switch off the ignition (this will close the solenoid
valves on the natural gas tanks automatically);
■ Open the doors to ventilate the vehicle sufficiently;
■ Immediately extinguish cigarettes, and remove and switch off other spark-
or fire-causing objects from the vehicle immediately. ■ Seek help from a specialist garage to correct the gas system fault.
■
The following are considered faults on the gas system:
■ Gas leakage from any part of the gas system as well as an error on the
ventilation system.
■ Continuous gas venting through the safety valves.
■ Cracks or damage that could result in a gas leak.
■ Fault in the reduction device, the pressure regulator, gas mixer or in the
injection valves, the pressure gauge, the shut-off or check valves and tank
fixtures.
■ If gas flows into the gas mixer or into the injection valves though the en-
gine is stopped.
■ Exceeding the permissible limits for contaminants in the exhaust gas.
■
Regular gas system checks must be carried out in order to operate a natural
gas vehicle. The vehicle owner is responsible for properly conducted tests.
■
The natural gas tanks must not be exposed to a heat source.
■
Always switch off the ignition in case of an accident or vehicle fire!
■
It is prohibited to drive into automatic car washes, enclosed storage places,
garages and similar areas where it is specifically forbidden to enter with CNG vehicles.

RefuellingFig. 100
Fuel filler
First read and observe the introductory information and safety warn-ings on page 123.
The gas filler tube for refuelling with natural gas is located behind the fuel filler
flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in handling.
When refuelling with natural gas at unfamiliar refuelling systems, you should
seek help from trained fuel station staff. If unsure, have the refuelling done by
trained fuel station staff.
The operating instructions of the refuelling system must always be followed.

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.
