the windscreen.
● Set temperature control to warmest level.
● Switch on heated rear window Ü.

Return to automatic air distribution:
Deactivate corresponding setting or
press AUTO .
Cooling n
Press n to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running
and climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit an Autostop.
Stop-start system 3 139.
Eco appears in the display when
cooling is deactivated.
Air recirculation mode 4
Press 4 once to activate the
manual air recirculation mode.9 Warning
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.
Air conditioning with the engine
not running
When ignition is off, the residual heat
or cooling in the system can be used for climate control in passenger
compartment.
Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Driving and operating139Starting the vehicle at lowtemperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. 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.
five 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
or to hold Engine Start/Stop pressed.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.Possible reasons for a non-starting
engine:
● Clutch pedal not depressed (manual transmission).
● Brake pedal not depressed or selector lever not in P or N
(automatic transmission).
● Timeout occurred
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.
Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A battery sensor ensures
that an Autostop is only performed if the battery is sufficiently charged for
a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
Driving and operating141Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 135.
Vehicle 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 auxiliary electric
heater or 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 driver
Depress the clutch pedal to restart the
engine.
The engine start is indicated by the needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, - with a message is shown in
the Driver Information Centre.Restart of the engine by the stop-
start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during engine restart might be
noticeable.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the parking
brake without pressing the
release button. Apply as firmly
as possible on a downhill slope
or uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
170Driving and operating9Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Push flap
and open.
Turn the fuel filler cap slowly
anticlockwise to open.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After automatic cut-off, the tank can be topped up by operating the pump
nozzle a maximum of two more times.Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Liquid gas refuellingFollow the operating and safety
instructions of the filling station when
refuelling.
The filling valve for the liquid gas is
behind the fuel filler cap.
