• the engine temperature is above 40°C (as soon as the engine
is warmed up, the warning light -4- in the dash panel insert
goes out)
• the outside temperature is above -10°C
• the engine speed is above 1200 rpm
• there is enough fuel in the LPG reservoir - at least the minimum
level indicated (the fuel level in the LPG reservoir is indicated
by the fuel gauge -1- in the dash panel insert or observe the
range specifications in the multi-function display -3-)
• the lambda probe is ready (waiting time at least approx. 30s)
⇒ page 89

⇒ "3.17.4 Querying the event memory of the LPG control unit",
page 92
The text "System switches to petrol mode" appears in the infor‐
mation display -3-.
If the engine switches successfully to LPG operation, this is dis‐
played by the warning light -2- lighting up in the dash panel insert
and the text "Engine is running in gas mode" appears in the in‐
formation display -3-.
Note
The waiting time for the change-over to LPG mode does not
♦
only depend on the lambda probe being ready for operation
(waiting time at least approx. 30s) but also on the operational
readiness of the complete LPG system. This may take a few
minutes.
The engine always starts in the petrol mode. The system will
♦
change over to LPG mode automatically if the conditions for
the change-over are fulfilled
Various texts concerning the complete LPG system are shown
♦
in the information display of the dash panel insert (including
LPG fueling), e.g. "The gas mode is not possible at present.
Owner's manual!" ⇒ Vehicle Owner's Manual .
Testing leak-tightness
– Use the gas leakage detector for natural gas vehicles - VAS
6227- to check if leaks can be found on the gas system.
On the gas leak detector for natural gas vehicles -VAS 6227- as
a result, only the green LED light is OK. As soon as a yellow or
red LED lights up, the leak must be remedied by a repair and then
the leak test of the LPG gas system must be repeated.
If a gas leakage detector for natural gas vehicles other than -VAS
6227- is used, the limit value of 50 ppm applies. Do not exceed
this limit value.
