Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.
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.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
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
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

136Driving and operatingConditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the vehicle battery is sufficiently charged 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 defrosting function is not activated
● 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
3 140
● 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 3 114.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 132.
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 N
(or A/M ) 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 green 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.

● Explosive gas may be present in the vicinity of the battery.
Additional battery
Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery mounted under
the right-hand front seat.
Notice
The additional battery is
automatically connected to the main vehicle battery only when the engine
is running. It does not need to be
manually disconnected before
disconnecting the main vehicle
battery or before jump starting the vehicle.
Jump starting 3 211.
Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screws on the filter cover and on the
lower part of the filter by approx. one
turn, to drain off the water.
The filter is drained as soon as diesel fuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
182Vehicle careFill the tank with fuel and proceed asfollows:
1. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
2. Loosen the vent screw (arrowed) by one turn.
3. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
4. Retighten the vent screw.
In vehicles without an in-line supply
pump, fill the tank with fuel and
proceed as follows:Caution
Do not turn ignition key to position 3 before beginning the bleeding
procedure.
Ignition switch positions 3 132.
1. Turn ignition key to position 2 and
hold for five seconds.
2. Turn key back to position 1 and
wait for three seconds.
3. Repeat Step 1 and 2 multiple times.
4. Turn key to position 3, then return
to 0.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
Wiper blade replacement
Wiper blades on the windscreen If required, use the step located below
the headlights to reach the
windscreen wiper.Lift wiper arm, press retaining clip
towards wiper arm and detach wiper
blade.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.
