Driving and operating137Starting 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 exhaust filter may take place more
often. Autostop may be inhibited to
allow for charging the vehicle battery.

Retained power off
The following electronic systems can
work until the driver's door is opened
or for a maximum of 10 minutes after
the ignition is switched off:
● power windows
● power outlets
Starting the engine
Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
'Automatic Starter Control'.
138Driving and operatingBefore restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Starting the vehicle at low
temperatures
Starting 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 vehicle battery.
With temperatures below -30 °C the
automatic transmission needs a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
Automatic Starter Control This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on
starting automatically until the engineis running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Timeout occurred.
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 pedal 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 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 vehicle battery sensor
ensures that an Autostop is only
performed if the vehicle 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.
Driving and operating141● Always apply the parkingbrake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress

slope, engage reverse gear or
set the selector lever to position
P before removing the ignitionkey. Turn the front wheels
towards the kerb.
● Close the windows and the soft
top.
● 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
be removed when the selector
lever is in position P.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 190.
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.
146Driving and operatingThe vehicle must be parked on a levelsurface.

Upshift indication 3 91.
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 90.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
152Driving and operatingTo reduce the operating forces ofthe parking brake, depress the
brake pedal at the same time.

m is pulled at the same time.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electric parking brake
is indicated by control indicator j and
by a vehicle message which is
displayed in the Driver Information
Centre.
