222Climate controlMaintenanceAir 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.
Air 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 outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
3 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 checkNotice
Refrigerant R-134a may contain
fluorinated greenhouse gases with a global warming potential of 1430.
Front air conditioning system is filled
with 0.58 kg and has a CO 2
equivalent of 0.83 tonnes, the front
and rear air conditioning system in
Combi variants is filled with 1.1 kg
and has a CO 2 equivalent of
1.57 tonnes and the front and rear air
conditioning system in Bus variants
is filled with 1.7 kg and has a CO 2
equivalent of 2.43 tonnes.
Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.
224Driving and operatingDriving hints
Driving economically
ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. When activated ECO
appears in the Driver Information
Centre.
During driving, it is possible to
temporarily disable ECO mode, e.g. to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press ECO again. ECO disappears in
the Driver Information Centre.
Driver Information Centre 3 104.
Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 227.Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats which fit properly
and are fixed by the retainers on the
driver's side.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
Driving and operating229● the vehicle battery is sufficientlycharged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the altitude is not too high
● the slope is not too steep
● the defrosting function is not activated
● the parking assist is not in operation
● the climate control system does not inhibit an Autostop
● the rear air conditioning system is
not activated
● the brake vacuum is sufficient ● the self-cleaning function of the diesel particle filter is not active
3 232
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 207.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 225.
Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driverManual transmission
With the selector lever in neutral,
depress the clutch pedal to restart the
engine.
Notice
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.If the engine does not restart first
time, depress clutch pedal fully again.Manual transmission automated
With the selector lever in position D,
M or N and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing the accelerator pedal may also restart
the engine.
The control indicator Ï will extinguish
in the instrument cluster when the
engine is restarted. If certain
conditions are not fulfilled, a restart will not take place. Start using the
ignition key.
Starting the engine 3 226.
Bus
The engine is restarted automatically
when operating the power sliding
door switch on the instrument panel
during an Autostop.
