118Driving and operatingTurbo 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.
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.On vehicles with manual
transmission, the engine is started 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.
DeactivationDeactivate the stop-start system
manually by pressing eco. The
deactivation is indicated when the
LED in the button extinguishes.
AutostopVehicles with manual transmission:
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Move the selector lever to neutral.
● Release the clutch pedal.
The engine will be switched off while
the ignition stays on.

General information When the trailer hitch is attached,
change the configuration settings in
the vehicle personalisation menu in
the Info Display.Vehicle personalisation 3 90.
When attaching a trailer or bike
carrier to the trailer hitch, the parking
assist is deactivated.
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver via acoustic and visual
signals.
The system has four ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 m. The interval between the
Driving and operating133sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approximately 30 cm, the sound is
continuous.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Driver
Information Centre with Uplevel
Display 3 80 or, depending on the
version, on the Colour Info Display
3 85.
Deactivation
The system automatically switches
off when reverse gear is disengaged.
Manual deactivation is also possible
by pressing r.
In both cases the LED in the button extinguishes.
Fault
In the event of a fault or if the system does not work temporarily, e.g.
because of high external noise level
or other interference factors, the LED
in the button flashes for 3 seconds
and then extinguishes. Control
indicator r illuminates in the
instrument cluster 3 77 and a
message pops-up in the Driver
Information Centre.
Front-rear parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. It informs and
warns the driver via acoustic signals
and display indication.
The system has six ultrasonic parking
sensors in both the rear and front
bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
136Driving and operatingAfter a manual deactivation, the front-rear parking assist is activated again
if D is pressed.
The complete system can be
manually deactivated in the vehicle
personalisation menu in the
Info Display. It remains deactivated
during the ignition cycle or until
activated in personalisation menu
again.

Vehicle messages 3 87.Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using

trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 80 or,
depending on the version, on the
Colour Info Display 3 85, supported
by acoustic signals.
The driver must control acceleration,
braking and gearshifting, while
steering is done automatically.
Advanced parking assist can only be activated when driving forwards.Advanced parking assist is always
combined with front-rear parking
assist, see previous section. Both
systems use the same sensors in the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist both use the same
button for activation and deactivation:
A brief press of D activates or
deactivates the parking assist.
A long press of D (approx.
1 second) activates or deactivates the
advanced parking assist, see
separate description below.
