116Climate control
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling n is
switched on.
If the maximum temperature Hi is set,
the climate control system runs at
maximum heating.
Notice
If n is switched on, reducing the set
cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.
Demisting and defrosting the
windows V
■
Press button V. Activation is
indicated by the LED in the button.
■ Temperature and air distribution are set automatically and the fan
runs at high speed.
■ Switch on heated rear window Ü.
■ To return to previous mode: press button V, to return to automatic
mode: press button AUTO.
Setting of automatic rear window heating can be changed in the
Info-Display. Vehicle personalisation

Notice
If the V button is pressed while the
engine is running, an Autostop will
be inhibited until the V button is
pressed again.
If the s button with activated fan is
pressed while the engine is running,
an Autostop will be inhibited until the s button is pressed again or until the
fan is deactivated.
If the V button is pressed while the
engine is in an Autostop, the engine will restart automatically.
If the s button is pressed with
activated fan while the engine is in an Autostop, the engine will restart
automatically.

120Climate controlAir 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

124Driving and operating
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
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 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 more
details 3 114.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 121.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
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, control indicator - illuminates
or is shown as a symbol in the Driver
Information Centre.
Control indicator - 3 86.

198Vehicle careCaution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax painted parts of the vehicle
regularly (at the latest when water no
longer beads). Otherwise, the
paintwork will dry out.
The foldable sunroof must not be
polished or waxed. When using
automatic car washes, select a
programme without wax additives.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Unpainted plastic body parts must not be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with these
parts.Matt painted decor parts, e.g. mirror
housing cover, must not be polished. Otherwise these parts would become
agleam or the colour would be
dissolved.
Windows and windscreen wiper blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
