swivelling the slats.
Adjust the air flow to select the
desired speed.
Fixed air vents Additional air vents are located
beneath the windscreen, the door
windows and in the foot wells.
Glovebox cooler The air conditioning system drawscooled air into the glovebox through a
noozle.Turn the slider up or down in order to enable or disable glovebox cooling.Maintenance
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.
150Climate controlAir conditioning regularoperation
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
Driving and operating157With touchscreen
The stop-start system can be
deactivated in the vehicle
personalisation 3 123.
If the system is deactivated during an
Autostop, the engine restarts
immediately.
AutostopVehicles with manual transmission
An Autostop can be activated at a
standstill or at speed below 12 mph.
Activate an Autostop as follows: ● Depress the clutch pedal.
● Set the selector lever to neutral.
● Release the clutch pedal.
The engine will be switched off while the ignition stays on.Vehicles with automatic transmissionIf the vehicle is at a standstill with
depressed brake pedal or gear
selector in N, Autostop is activated
automatically.
In case of vehicles with automatic
transmission of type B, an Autostop
can also be activated at a speed below 12 mph.The engine will be switched off while
the ignition stays on.
Indication
An Autostop is indicated by control
indicator ñ.
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 driver's door is closed or the driver's seat belt is fastened.
● The sliding doors are closed
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The ambient temperature is between 0 °C and 35 °C.
● 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 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.
Notice
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop.
Climate control 3 140.
Immediately after higher speed
driving an Autostop may be inhibited.
158Driving and operatingNew vehicle running-in 3 152.
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 such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without
depressing the brake pedal to restart the engine.
Vehicles with automatic transmission Type A: The engine is restarted if
● the gear selector is in position D
with M activated or not and the
brake pedal is released● the gear selector is in position N,
the brake pedal is released and
the gear selector is moved to
position D with M activated or not
● the gear selector is in position P,
the brake pedal is depressed and the gear selector is moved to
position R, N or D with M
activated or not
● the reverse gear is engaged
Type B: The engine is restarted if ● the gear selector is in position A
or M and the brake pedal is
released
● the gear selector is in position N,
the brake pedal is depressed and and the gear selector is moved toA or M
● the reverse gear is engaged
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:● depending on engine, vehicle speed exceeding 0.6 mph or
15 mph(manual transmission)
● vehicle speed exceeding 0.6 mph (automatic
transmission)
● stop-start system manually deactivated
● driver's door opened
● sliding door opened.
● driver's seat belt unfastened
● engine temperature too low
● charging level of vehicle battery below defined level
● brake vacuum not sufficient
● vehicle driven at least at walking speed
● climate control system requests engine start
● air conditioning manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
