WARNING
• When working on the natural gas system, the battery earth
strap must be disconnected.
• After the service, installation and repair work on the liq‐
uefied petroleum gas system (LPG), a leak tightness test
on the gas system inspection must always be carried out
⇒ "3.18.3 Inspect natural gas system for leak-tightness",
page 80 .
• Only system components of the same type and with the
same design approval for the manufacture can be re‐
placed.
• The components of the natural gas system on which the
repair and maintenance work is to be carried out, must be
discharged before
⇒ "3.18.5 Empty natural gas system (deactivate)",
page 85 or the gas must be released.
♦ When undertaking all installation work, particularly in the
engine compartment due to its cramped construction,
please observe the following:
♦ Install the components of the natural gas system in such
a way that the original cable guide of the natural gas sys‐
tem is re-established.
♦ Ensure that there is adequate free access to all moving or
hot components, in order to avoid damage to the cables
of the natural gas system.
♦ The cables on the natural gas system must not be bent.
Every natural gas tank is fitted with a solenoid valve, which
closes automatically after switching off the ignition or in petrol
mode.
A safety valve is also fitted to every natural gas tank (excessive
heat and pressure build-up). This safety valve prevents un‐
controlled pressure build-up in the natural gas tank in case of
fire.
A flow limiter prevents a sudden emptying of the natural gas
tank in the event of damage to the pressure system.
Rules of cleanliness
For all tasks on the liquefied petroleum gas system, carefully pay
attention to the following "rules of cleanliness":
♦ Thoroughly clean the connection points and their surroundings
before releasing.
♦ Place removed parts on a clean surface and cover.
♦ Do not use fluffy cloths!
♦ Carefully cover or close opened components if the repair is not
completed immediately.
♦ Only install clean components: Remove the spare parts from
their wrapping immediately before installation. Do not use any
parts which have been stored unwrapped (e.g. in tool boxes
etc.).
♦ When the system is open: Avoid using compressed air when‐
ever possible. Avoid moving the vehicle.
