Instruments and controls1039Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle is stationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check engine oil level 3 271.
Keep engine turned off and let the
vehicle be towed to a workshop.

Climate control213Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
9 Warning
If the warning light illuminates in
combination with the hazard
warning flashers, stop vehicle and switch off engine as soon as
possible. Evacuate the vehicle, there is a risk of fire.
216Climate controlCombi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
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 engine-independent, fuel-
powered coolant heater provides rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.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, set the
air distribution to V and turn the fan
on.
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.

When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 m. The range may be
reduced due to environmental
conditions and as the battery
becomes weaker.

additional teaching processes, the
oldest transmitter will be deleted each
time.
Remove the heater fuse for
5 seconds, then refit the fuse. Within 2–6 seconds press OFF for
1 second. Teaching is completed.
If the remote has not been used for a long period, press the OFF button
6 times at intervals of 2 seconds, then
press and hold for another
2 seconds, then wait 2 minutes.

Driving and operating263Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester).
Paraffinic Diesel fuel that meets
standard EN15940 mixed with a
biofuel that meets standard
EN14214 (possibly containing up to
7% Fatty Acid Methyl Ester).
If travelling in countries outside the
European Union, occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.
Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines. Do not use additives.
The flow and filterability of diesel fuels are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Diesel fuel system bleeding 3 276.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage to the fuel
injection system.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
