106Instruments and controlsTachometer
Displays the engine speed.
Drive in a low engine speed range for each gear as much as possible.
Caution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the fuel level or gas content
(CNG) in the tank depending on the current operation mode.
The arrow indicates the vehicle side
where the fuel filler flap is located.
For bi-fuel engines, the Driver
Information Centre displays the fuel
level for the fuel type which is
currently not in operation. The fuel
level for the fuel type which is
currently in operation is shown in the fuel gauge.
Control indicator Y illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified fuel tank capacity.
Fuel selector
Natural gas operation (CNG)
Press X to switch between petrol and
natural gas operation.
The LED status shows the current
operating mode.

Switching is not possible at high loads (e.g. powerful acceleration, driving at
full throttle).
If the selector switch is operated
several times within a short time, a
switchover inhibitor is activated. The
engine remains in the current
operating mode. The inhibitor
remains active until the ignition is
switched off.
A slight loss of power and torque can
be expected during petrol operation.
You must therefore adapt your driving style, e.g. during overtaking
manoeuvres and high vehicle loads
(e.g. towing loads) accordingly.
The vehicle consumes petrol when
starting the engine and even when in
certain natural gas operating modes. The petrol consumption in natural gas
operating mode can vary depending
on driving behaviour (e.g. high load or
towing). In case of a low fuel level, a
corresponding message is displayed
as a reminder to refuel.
Note
Always ensure that there is enough
petrol in the tank.
Fuel for natural gas operation 3 219.
Forced fuel mode transitionNatural gas tank is running low
As soon as the natural gas tank is
empty, petrol operation is
automatically engaged. Manually
engaging natural gas operation mode is not possible until natural gas
refuelling is detected.
Before the petrol fuel system runs empty, a warning message will be
displayed and cannot be dismissed.Petrol tank is running low while
natural gas is available
If the remaining petrol level in the tank falls below a certain level, natural gas
operation is automatically engaged
provided there is a sufficient natural
gas level in the tank. Manually
engaging petrol operation mode is not
possible.
Before both fuel systems run empty,
a warning message will be displayed
and cannot be dismissed.
