106Climate controlAuxiliary 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 turnsthe system on and off, and is used to
programme specific departure times.Timer1 X

optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
114Driving and operatingStarting 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.

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.
Driving and operating117Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 3 117.
Vehicle 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 (DIC)3 89.9 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.
Resetting with remote control
key / manual key
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 2
3 114.
2. Wait a few minutes to allow the fuel system to be reset.
3. Turn key to position 3 to start the
engine.
If the engine does not start, repeat the
procedure.

Refuelling 3 138.
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.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
118Driving and operatingActivation
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.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 88.
Deactivation
Deactivate the stop-start system
manually by pressing Î. LED in the
button illuminates to indicate
deactivation and a corresponding message appears in the Driver
Information Centre (DIC) 3 89.
If deactivated manually, it is possible to reactivate the stop-start system by
pressing Î again.
Vehicle messages 3 90.
Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Î . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information
Centre (DIC) 3 89.
Idle speed control 3 116.
Autostop
If the vehicle is at a low speed or at astandstill, activate an Autostop as
follows:
● depress the clutch pedal● move the selector lever to neutral
● release the clutch pedalThe engine will be switched off while
the ignition stays on.
An Autostop is indicated when Ï
illuminates in the instrument cluster
3 88.
During an Autostop, heating and
brake performance will be
maintained. However, brake assist is
not available 3 127.
Caution
The steering assist may be
reduced during an Autostop.
Driving and operating127driving, there is a fault in the ABS.
Control indicator F 3 85 may also
illuminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre (DIC). The brake system
remains operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, F , R 3 85
and C 3 85 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the DIC 3 89. Have the
cause of the fault remedied by a
workshop.
Vehicle messages 3 90.
Parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
Control indicator R 3 85.
Parking 3 120.
Brake assist If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Brake assist is not available during an
Autostop.
Stop-start system 3 117.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
Vehicle care151
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by approx. one turn, to drain off the
water.
The filter is drained as soon as water-
free diesel fuel emerges. Retighten
the screw.
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.
Refuel then proceed as follows:
With ignition key
● Switch on the ignition (key to position 2) for 5 seconds at a
time.
● Switch off ignition (key to position
1 ) for 3 seconds.
● Repeat this process multiple
times.
● Start the engine (key to position 3) then switch off (key to position
0 ).
