Climate control127Air 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
Notice
Refrigerant R-134a contains
fluorinated greenhouse gases.
132Driving and operatingDuring 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 exhaust 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 more
details 3 121.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 129.
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.
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 88.Vehicles with manual transmission
automated:
Release the brake pedal or move
selector lever out of D to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
Driving and operating133If one of the following conditionsoccurs 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 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.
● If the vehicle is on a level surface or uphill slope, engage
first gear before removing the ignition key. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before removing the ignition
key. Turn the front wheels
towards the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with manual
transmission automated, the key can only be removed from
the ignition switch when the
parking brake is applied.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 167.
