not reset the fuel cut-off system, to avoid the risk of fire.
Fuel system messages 3 94.
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.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system
The stop-start system helps to save
fuel and to reduce 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
starts the engine automatically as
soon as the clutch is depressed.
A vehicle battery sensor ensures that an Autostop is only performed if thevehicle battery is sufficiently charged
for a restart.
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.Deactivation
Deactivate the stop-start system
manually by pressing ^ in the centre
console. LED in the button illuminates
to confirm deactivation.
Depending on version, a
corresponding message, e.g.
Start&Stop disconnected , may also
be displayed in the Driver Information
Centre 3 88.
Driving and operating115Restarting the engineManual transmission
The selector lever must be in neutral to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
● the driver's seat belt is unfastened and the driver's door
is opened
● three minutes have elapsed since the engine was switched offIn this event, control indicator ^
flashes in the Driver Information
Centre in conjunction with a warning
chime. Depending on version, a
corresponding message may also be
displayed in the Driver Information
Centre 3 88.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 87.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A
corresponding warning message,
e.g. Start&Stop unavailable , may also
be displayed in the Driver Information
Centre 3 88.
Generic warning 9 3 79.
Seek the assistance of a workshop.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear before switching off
the ignition. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before switching off the ignition. Turn the front wheels towardsthe kerb.
116Driving and operating● Close the windows.
● Turn the ignition key to position
0 and remove it from the
ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
● Lock the vehicle 3 23.
● Activate the anti-theft locking system 3 28.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain
time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs 15 minutes. Autostop is not
available and fuel consumption may
be higher during this period. The
emission of smells and smoke during
this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Depending on version, a warning
message may also appear in the
Driver Information Centre 3 88.
Driving and operating131Fuel selector
Pressing Y in the centre console
switches between petrol and natural
gas operation. The LED 1 status
shows the current operating mode.
1 off:natural gas
operation1 illuminates:petrol operation
As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 88 until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Refuelling
Fuel filler flap is located at left rear
side of vehicle.9 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.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Release the fuel filler flap by pulling
the flap by hand.
Insert ignition key into fuel filler cap
and turn anticlockwise to unlock.
To remove fuel filler cap, rotate
anticlockwise.
Caution
To avoid damage, do not attempt
to operate the sliding side door
when the fuel filler flap is open.
132Driving and operatingNotice
Depending on model, the sliding
side door may be fitted with a safety system that prevents the door from
being opened fully when the fuel
filler flap is open.
Sliding side door 3 25.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After automatic cut-off, the tank can be topped up by operating the pump
nozzle a maximum of two more times.
Caution
Wipe off any overflowing fuel
immediately.
To close, replace fuel filler cap and
turn clockwise.
Insert ignition key into fuel filler cap
and turn clockwise to lock, then
remove key.
Close the fuel filler flap.
Natural gas refuelling
Open the fuel filler flap.
9 Warning
Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed, i.e. the filler neck must be vented.
The capacity of the natural gas tank
depends on outside temperature,
filling pressure and type of refuelling
system.
Close the fuel filler flap after
refuelling.
