132Driving and operating
Indication
An Autostop is indicated by the
Control indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
■ The stop-start system is not manually deactivated.
■ The bonnet is fully closed.
■ The driver's door is closed or the driver's seat belt is fastened.
■ The vehicle battery is sufficiently charged and in good condition.
■ The engine is warmed up.
■ The engine coolant temperature is not too high.
■The engine exhaust temperature is
not too high, e.g. after driving with
high engine load.
■ The ambient temperature is above -5 °C.
■ The climate control system allows an Autostop.
■ The brake vacuum is sufficient.
■ The self-cleaning function of the diesel particle filter is not active.
■ The vehicle was driven at least at walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 121.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 129.Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g. the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.

engine.
When the engine is restarted, the
control indicator D in the DIC
extinguishes.
Restart of the engine by the
stop-start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
■ The stop-start system is manually deactivated.
■ The bonnet is opened.
■ The driver's seat belt is unfastened
and the driver's door is opened.
■ The engine temperature is too low.
■ The charging level of the vehicle battery is below a defined level.
■ The brake vacuum is not sufficient.■ The vehicle is driven at least at
walking speed.
■ The climate control system requests an engine start.
■ The air conditioning is manually switched on.
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
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 the parking brake.
Activate the manual parking
brake without pressing the
release button. Apply as firmly
as possible on a downhill slope
or uphill slope. Depress foot
brake 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 or set the selector lever
to position P before removing
the ignition key. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position P before removing the ignition
key. Turn the front wheels
towards the kerb.
■ Close the windows and the sunroof.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only

134Driving and operatingbe removed when the selector
lever is in position P.
For vehicles with manual
transmission automated, the
key can only be removed from
the ignition switch when the park brake is applied.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
■ The engine cooling fans may run after the engine has been switchedoff 3 177.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
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

Driving and operating135
take up to 25 minutes. Typically it
needs between seven and
12 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 cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by control indicator %.
Simultaneously a warning message or warning code appears in the Driver
Information Centre.
% illuminates when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling
level. Start cleaning process
immediately to avoid damage to the
engine.
Cleaning process To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
If g illuminates additionally,
cleaning is not possible, seek the
assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
The control indicator % extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 168, 3 230 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

transmission is in automatic mode
and first gear is engaged. If R is
selected, reverse gear is engaged.
The vehicle starts to move when the
brake is released.
To start-off without depressing the
foot brake, accelerate immediately
after engaging a gear as long as D or
R flashes.
If neither the accelerator nor the
brake pedal are depressed, no gear
is engaged and D or R flashes for a
brief time in the display.
Stopping the vehicle
In D, first gear is engaged and the
clutch is released when the vehicle is
stopped. In R, reverse gear remains
engaged.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when
driving downhill. Changing into
manual mode is only possible with
running engine or during Autostop.

142Driving and operating
Rocking the vehicleRocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.Tyre pressure monitoring
system
To start the sensor matching process of the tyre pressure monitoring
system, the selector lever must be
moved and hold in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system

Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or
too high an engine speed. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 100.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication R with a number next is indicated,
when gear shifting is recommended
for fuel saving reasons.
Shift indication appears only in
manual mode.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.

Driving and operating143
KickdownIf the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual
transmission automated, the clutch is engaged automatically at high clutch
temperatures.
In the event of a fault, control indicator
g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 100.
Continued driving is restricted or not possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 89.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.
Control indicator u 3 89.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
