control indicator illuminates
continuously. Consult a workshop.
Engine oil pressure
I illuminates red.
Illuminates when the ignition is
switched on and extinguishes shortly
after the engine starts.
Illuminates when the engine isrunningCaution
Engine lubrication may be
interrupted. This may result in
damage to the engine and/or
locking of the drive wheels.
1. Depress clutch.
2. Select neutral gear, set selector lever to N.
3. Move out of the flow of traffic as
quickly as possible without
impeding other vehicles.
4. Switch off ignition.9 Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle is stationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking the
assistance of a workshop 3 220.

Driving and operating161
Cleaning takes place quickest at high
engine speeds and loads.
The control indicator % extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 204, 3 273 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
AdBlue General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust system.
The designation of the DEF used is AdBlue Ⓡ 1)
. It is a non-toxic, non-
flammable, colourless and odourless fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
Level warnings The AdBlue consumption is approx.0.7 litres per 1000 km and depends
on the driving behaviour.

166Driving and operating
In manual mode no automatic shiftingto a higher gear takes place at high
engine revolutions.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The automatic neutral shift function
automatically shifts gear to idling
when the vehicle is stopped with a
forward gear engaged and the
brake pedal is pressed.
■ When SPORT mode is engaged, the vehicle shifts at higher engine
speeds (unless cruise control is
on). SPORT mode 3 172.■ Special programmes automatically
adapt the gearshift points when
driving up inclines or down hills.
■ When starting-off in snowy or icy conditions or on other slippery
surfaces, the electronic
transmission control selects a
higher gear automatically.
Kickdown If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear depending on engine speed.
Fault In the event of a fault, g illuminates.
Additionally a code number or a
vehicle message is displayed in the
Driver Information Centre. Vehicle
messages 3 121.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.Only the highest gear is available.
Depending on the fault, 2nd gear may also be available in manual mode.
Shift only when vehicle is at a
standstill.
Have the cause of the fault remedied by a workshop.
Interruption of power
supply In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 258.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.

Driving and operating205
Fuel selector
Pressing button Y switches between
petrol and natural gas operation.
Switching is not possible at high loads
(e.g. strong acceleration, running at
full throttle). The LED status shows
the current operating mode.
1 off=natural gas
operation.1 illumi‐
nates=petrol operation.1 flashes=no switching is
possible, one type of
fuel is empty.As soon as the natural gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is started-up again. This
will prevent damage to the catalytic
converter (overheating caused by
irregular fuel supply).
If the selector switch is operated
several times within a short time, a
switchover block is activated. The engine remains in the current
operating mode. The block 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 vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This isnecessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.
Fuel for liquid gas
operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).
