Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines.
Diesel engines
The start of the engine without
additional heaters is possible down to -25 °С.
Petrol engines
The start of the engine without
additional heaters is possible down to
-30 °C.Required is an engine oil with the
correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
With temperatures below -30 °C, the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position
P .
Automatic starter control This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
Once applied, the system will go on
starting automatically until the engine is running. Because of the checkingprocedure, the engine starts running

Driving and operating173
Every six months, run the petrol tank
down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
