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.
● 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.
● The engine cooling fans may run
after the engine has been
switched off 3 142.
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
switched off automatically if the
vehicle comes to a standstill within a
certain time.

120Driving and operatingEngine exhaust9Danger
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 90.
Control indicator % illuminates when
diesel particle filter is full. Start
cleaning process as soon as possible to avoid damage to the engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.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.
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.

Driving and operating125Eco mode selects the most suitable
gear depending on the speed of the
vehicle, the engine speed and the
intensity with which the accelerator is
pressed.
Activation
Press E on the selector lever housing.
Control indicator E is shown in the
transmission display to indicate
activation.
Deactivation
Eco mode is switched off by:
● pressing E again
● switching to manual mode
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning chime may sound. In such cases, depress
the brake pedal, select N and apply
the parking brake to allow the clutch
to cool down.
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower geardepending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator s is shown in the transmission
display.
Continued driving is possible,
provided the vehicle is driven with
care and anticipation. A warning
message may appear in the Driver
Information Centre in conjunction with
a warning chime 3 95.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 90.
Have the cause of the fault remedied by a workshop.

The Hill start assist is not active
during an Autostop.
Stop-start system 3 116.Ride control systems
Traction Control system The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Control (ESC).
ASR improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ASR is operational after each engine
start as soon as the control indicator
R extinguishes.
When ASR operates, R flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Driving and operating129Deactivation
ASR can be switched off when
spinning of drive wheels is required:
press ASR OFF briefly.
LED in button illuminates and,
depending on version, a
corresponding message, e.g. ASR
disconnect , may also be displayed in
the Driver Information Centre 3 90.
ASR is reactivated by pressing
ASR OFF again.
ASR is also reactivated the next time
the ignition is switched on.
Fault
ASR will switch off automatically in the event of a fault. Control indicator
R will illuminate in the instrument
cluster. Depending on version, a

Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as control indicator R
extinguishes.
When ESC operates, R flashes.
The ESC system is automatically
activated when the vehicle is started
and cannot be deactivated.
