Natural gas fuel gauge 3
The display indicates tank pressure or
petrol level, depending on operating
mode.Display:
1/1 - Tank pressure approx. 200 bar
3/4 - Tank pressure approx. 150 bar
1/2 - Tank pressure approx. 100 bar
1/4 - Tank pressure approx. 50 bar
In order to achieve the maximum range in
natural gas operation, we recommend that
you make use of the entire reserve area. Petrol operation:
Display:
1/1 - Tank content approx. 14 litres
When the petrol level is getting low, the
engine may sputter when taking curves.
Refuel immediately if control indicator Y
begins to flash!
Never allow the petrol tank to run dry!On vehicles with auxiliary heating 3,
regularly check the petrol level as it
consumes petrol even during natural gas
operation.

114 Driving and operationIf the natural gas tank is then not refilled,
petrol operation must be manually
selected the next time the engine is started.
This is necessary in order to prevent
damage to the catalytic converter
(overheating due to irregular fuel supply).
If the switch is pressed several times within
a brief period of time, a changeover
inhibitor is activated. The engine continues
with the current type of fuel. The inhibitor
remains active until the ignition is switched
off.
Minor power and torque losses are to
be expected during petrol operation,
therefore adjust driving style (e.g.
overtaking) and vehicle load (e.g. through
trailer load) accordingly.
Every 6 months, run the petrol tank down
to the reserve zone before refuelling. This is
necessary for petrol operation to obtain
the required system functionality and fuel
quality.Note:
Refuel and operate only w i t h f u e l o f a t l e a s t
95 octane (RON). Upon accidental
refuelling with petrol of an
octane rating (RON) less than 95, avoid
driving with fuel load (e.g. heavy
acceleration, full throttle), allow the tank to
reach the reserve zone and refuel with the
correct petrol.
In order to prevent corrosion in the tank,
please refuel the vehicle to the maximum
level at regular intervals.

Catalytic converter, engine
exhaust Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas, such as carbon monoxide
(CO), hydrocarbons, (CH) and nitrous
oxide (NO
x).
Fuel grades other than those listed on
3110, 184 (e. g. LRP = Lead Replacement
Petrol or leaded fuel) could damage the
catalytic converter or electronic
components.
Caution
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed.
