100Climate control
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heater
Coolant heater The Eberspächer engine-
independent, fuel-powered coolant heater provides rapid heating of the
engine coolant to enable heating of
the vehicle interior without the engine
running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's climate control system to heat and the
air distribution to V.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.Timer1 X

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.

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.
