142Driving and operatingOverrun 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.
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.Deactivation
Deactivate the stop-start system
manually by pressing eco. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop 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.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating and
brake performance will be
maintained.
Caution
The steering assist will be reduced
during an Autostop.
156Driving and operatingResume stored speed
Turn thumb wheel to RES/+ at a
speed above 30 km/h. The stored
speed will be obtained.
Switching off
Press rocker switch m at the lower
end, control indicator m extinguishes.
The stored speed is deleted.
Switching off the ignition also deletes
the stored speed.
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 parking assist makes parking easier by measuring the distance
between the vehicle and obstacles,
and giving acoustic signals.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist, the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Control indicator r 3 97.
Operation
When reverse gear is engaged, the
front and rear parking assist is ready
to operate.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
The front parking assist can also be activated at a speed up to 11 km/h
with a brief press of the parking assist
button.
If r is pressed once within an
ignition cycle, the front parking assist
is deactivated at a speed above
11 km/h. It will be reactivated if
vehicle speed has not exceeded
Driving and operating15725 km/h beforehand. If vehicle speed
has exceeded 25 km/h beforehand,
front parking assist remains
deactivated when speed drops below 11 km/h.
When the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
The system is deactivated
automatically when exceeding
25 km/h.
If the vehicle is equipped with rear
parking assist only, the system
automatically switches off when
reverse gear is disengaged. Manual
deactivation is also possible by
pressing r.
Indication An obstacle is indicated by a buzzing
sound. The interval between the
sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.Fault
In the event of a fault in the system,
r illuminates or a vehicle message
is displayed in the Driver Information
Centre.
Additionally, r illuminates or a
vehicle message is displayed in the
Driver Information Centre if a
malfunction of the system due to
temporary conditions like snow
covered sensors is detected.
Vehicle messages 3 106.
Important hints for using the
parking assist systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection
area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.Caution
Performance of the sensors can
be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
The parking assist system will not
avoid a collision with objects which are out of the detection range of
the sensors.
158Driving and operatingNote
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
Note
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r briefly to
deactivate the parking assist.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding behind and
around the vehicle before
reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
