104Climate control
Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents.
Switch on the fan while the air
conditioning system is operating to
allow cooled and dehumidified (dried) air to be distributed.
The rate of air flow is determined by
the fan.
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.Caution
Do not touch the exhaust pipe. It
may be hot even after the engine
has been switched off, due to
coolant heater operation.
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat and the
air distribution to V.
9Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
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.

Notice
The remote control system features
a temperature sensor which
calculates the runtime according to
the ambient temperature and the desired heating level (ECO or
HIGH). The system starts
automatically between 5 and
60 minutes prior to the programmed
departure time.Set weekday, time and heating

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 the ECO button. Control
indicator ECO illuminates in the
instrument cluster when activated.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly. ECO flashes in the instrument
cluster.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal. ECO stops
flashing and illuminates continuously.
Deactivation
Press the ECO button again. Control
indicator ECO extinguishes in the
instrument cluster.
Driving and operating111Control of the vehicleNever coast with engine not
running
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.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
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
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
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.

Notice
Always take the electronic key with you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 89 and a message in the
Driver Information Centre 3 89 when
the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
■ Fault in electronic key.
■ Electronic key out of reception range.
■ Battery voltage too low.
■ Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
■ Interference from higher-power radio waves from other sources.

Do not accelerate.
Diesel engines: turn the key to
position M for preheating until control
indicator ! extinguishes in the
instrument cluster 3 86.
Turn key to position D and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to St.
During an Autostop, the engine can be started by depressing the clutch
pedal. Stop-start system 3 115.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Idle speed control
To increase the idle speed, press theswitch. After a few seconds the
function will be activated.
The function will be deactivated
when:
■ The clutch pedal is depressed
■ The accelerator pedal is depressed
■ Vehicle speed is above 0 mph
■ Control indicator F, W or C
illuminate in the instrument cluster
To increase or decrease the fast idle
speed rate, consult a workshop.
Driving and operating115Vehicle shutdown
Fuel cut-off system
If the vehicle runs out of fuel, the fuel system is cut-off and must be reset
after refuelling. A corresponding
warning message may also appear in the Driver Information Centre 3 88.9 Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have thecause of this remedied
immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.

Refuelling 3 132.
Overrun cut-off
The fuel supply is automatically cut off during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It restarts the engine
automatically as soon as the clutch pedal is depressed.
Activation The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
