Control of the vehicleNever coast with engine not
running (except during an Autostop)
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. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 116.
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.
Control indicator c 3 82.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.

Driving and operating115Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
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
battery.

116Driving and operating
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an
engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
With temperatures below -30 °C the
automatic transmission need a
warming phase of approx. 5 minutes. The selector lever must be in position
P .
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.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. Overrun cut-
off is deactivated if catalytic converter
temperature is high.
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 starts the engine
automatically as soon as the clutch is
depressed. A battery sensor ensures
that an Autostop is only performed if
the 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 the eco button.
The deactivation is indicated by the
LED in the button going off.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
■ Depress the clutch pedal
■ shift the selector lever to neutral
■ release the clutch pedal
The engine will be switched off while the ignition stays on.

120Driving and operating
The control indicator ! extinguishes
as soon as the self-cleaning
operation is complete.
If A illuminates additionally, cleaning
is not possible, seek the assistance of
a workshop.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 134, 3 202 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.
Automatic transmission
The automatic transmission permits
automatic gearshifting.
Transmission display
The mode or selected gear is shown
in the transmission display.
