Instruments and controls105The LED status shows the current
operating mode.LED off:petrol operationLED illu‐
minates:natural gas operationLED
flashes for
approx.
five
seconds:fuel mode transition is
selected but switching
is not possibleLED
flashes:fuel mode transition in
process, flashing stops
if transition is completed
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 3 218.
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.
Engine coolant temperaturegauge
Displays the coolant temperature.

If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Service display
The engine oil life system informs
when to change the engine oil and
filter. Based on driving conditions, the interval at which an engine oil and
filter change will be indicated can vary
considerably.
When the system has calculated that
engine oil life has been diminished,
Change Engine Oil Soon appears in
the Driver Information Centre. Have engine oil and filter changed by a
workshop within one week or
500 km, whichever occurs first.
This can be an additional engine oil
and filter change or part of a regular
service.
The remaining oil life duration menu
is displayed in the Driver Information
Centre 3 114.
On Midlevel display select the
Settings Menu by pressing MENU on
the indicator lever. Turn the adjuster wheel to select the Remaining Oil
Life page.

164Driving and operatingAn Autostop can be activated at a
speed lower than 5 km/h.
Activate a conventional Autostop as follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.
Early Autostop
Only the engine B16DTU has early
Autostop in addition to conventional
Autostop.
An Autostop can be activated at a
speed lower than 14 km/h.
Early Autostop is inhibited if the
incline is greater than 5%.
Activate an early Autostop as follows: ● Depress the brake pedal sufficiently.
● Depress the clutch pedal.
The engine will be switched off while
the ignition stays on.
Early Autostop is inhibited when the
turn lights are on, trailer hitch is
connected, the steering wheel is
moved beyond a certain point or the
inclines is greater than 5%.Vehicles with automatic transmission
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
After restart, the idle speed is
indicated.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
● The stop-start system is not manually deactivated.
● The bonnet is fully closed.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The brake vacuum is sufficient.
● Between the last restart and a new Autostop must be about10 seconds.
