112Climate control9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Auxiliary heater Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Coolant heater
Diesel-engined vehicles have a fuel-
powered auxiliary heater.Air vents
Adjustable air vents At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to
lack of air movement.
Set the direction of the air flow by
turning the adjuster wheel from right to left and raise or lower the horizontal slats.
Driving and operating117
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating
performance, power steering 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 battery is sufficiently chargedand 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 not too low
■ the defrosting function is not activated
■ 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 has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become less
available as the ambient temperature
approaches the freezing point.Certain settings of the climate control
system may inhibit an Autostop. See
climate control chapter for more
details.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 115.
Battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as rear window heating
are disabled or switched into a power saving mode. The fan speed of the
climate control system may be
reduced to save power.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
Driving and operating135Caution
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.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type
of fuel is empty
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
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.

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
The following must be carried out if
the vehicle is to be stored for several
months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.
146Vehicle care
■ Open bonnet, close all doors andlock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are not functional, e.g. anti-theft alarm
system.
Putting back into operation Following must be done if the vehicle
is putting back into operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate if necessary.
End-of-life vehicle
recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on ourwebsite, where legally required. Only
entrust this work to an authorised
recycling centre.
Gas vehicles must be recycled by a
service centre authorised for gas
vehicles.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
Vehicle care1479Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
The caps for topping up the engine oil, the coolant, the washer fluid and the
oil dipstick handle are yellow, for ease
of identification.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Lift the safety catch upwards and
open the bonnet.
Air intake 3 113.
Secure the bonnet support.
If the bonnet is opened during an Autostop, the engine will be restarted automatically for safety reasons.
Closing Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to drop
into the catch. Check that the bonnet
is engaged.
Vehicle care149
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
KALT/COLD mark. Top up if the level
is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
