Control of the vehicleNever 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 will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 108.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Power steering Never leave the steering wheel on full
lock when the vehicle is stationary as this may damage the power steering
pump.Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be inhibited to allow for charging the
vehicle battery.
Stop-start system 3 108.
Diesel particle filter 3 112.
138Vehicle care
Warning label
Meaning of symbols:■ No sparks, naked flames or smoking.
■ Always shield eyes. Explosive gases can cause blindness or
injury.
■ Keep the battery out of reach of children.
■ The battery contains sulfuric acid which could cause blindness or
serious burn injuries.
■ See the Owner's Manual for further
information.
■ Explosive gas may be present in the vicinity of the battery.
Battery maintenance9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Additional battery
Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery mounted under
the front seat.
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.
Vehicle care139Diesel fuel system
bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Fill the tank with fuel and proceed as
follows:
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.
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 windscreenLift 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.
Vehicle care155
7.Screw the sealant filler hose to the
tyre valve.
8. The rocker switch on the compressor must be set to
position O.9.
Connect the red < power supply
lead on the compressor to the
jump start terminal 3 160.
10. Connect the black ] power
supply lead to a vehicle grounding
point, e.g. the engine block or an
engine mounting bolt.
To avoid discharging the battery,
we recommend running the
engine.11. Set the rocker switch on the compressor to position I. The tyre
is filled with sealant.
12. The compressor pressure gauge briefly indicates up to 6 bar. Then
the pressure starts to drop.
13. All of the sealant is pumped into the tyre. Then the tyre is inflated.
