Climate control129Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ functionality and pressure test
■ heating functionality
■ leakage check
■ check of drive belts
■ cleaning of condenser and evaporator drainage
■ performance check

132Driving and operatingStarting the engine
Turn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Manual transmission automated:
operate brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn key briefly to position 3 and
release: an automatic procedure operates the starter after a brief
delay, until the engine is running. See
'Automatic Starter Control'.
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
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
after a short delay.
Possible reasons for a non-starting
engine:
■ clutch pedal not operated (manual transmission)
■ brake pedal not operated or selector lever not in P or N
(automatic transmission)
■ timeout occurred

134Driving and operating
Indication
An Autostop is indicated by control
indicator D.
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 climate control system allows an Autostop.
■ The brake vacuum is sufficient.
■ The self-cleaning function of the diesel particle filter is not active.
■ The vehicle was driven at least at walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for further
information 3 123.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 131.Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g. the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.
Restart of the engine by the
driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.
When the engine is restarted, control
indicator D in the Driver Information
Centre (DIC) extinguishes.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in
the DIC.
Control indicator - 3 91.

172Driving and operatingCaution
Use of fuel that does not comply toEN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
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).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after approx. 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.LED off=petrol operationLED illu‐
minates=liquid gas operationLED
flashes=checking of conditions
for fuel transition, or fuel
transition is denied
(message in the DIC
appears)
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.

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.
