Climate control109Notice
The remote control system features
a temperature sensor which
calculates the runtime according to the ambient temperature and thedesired heating level (ECO or
HIGH). The system starts
automatically between 5 and
60 minutes prior to the programmed
departure time.
Set weekday, time and heating
duration Ö
If the vehicle battery is disconnected
or its voltage is too low, the unit will
need to be reset.
● Select Ö and confirm.
● Select weekday and confirm.
● Change hours and confirm.
● Change minutes and confirm.
● Change the default heating duration and confirm.
Heating level Y
The preferred heating level for programmed departure times can be
set to either ECO or HIGH.Select Y and confirm. ECO or HIGH
flashes in the display. Adjust using
q or r and confirm.Air vents
Adjustable air vents
At least one air vent must be open
while cooling is on, in order to prevent the evaporator from icing up due tolack of air movement.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.

Driving and operating117Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated.

Vehicle shutdown
Fuel cut-off system
If the vehicle runs out of fuel, the fuel
system is cut-off and must be reset
after refuelling. A corresponding
warning message may also appear in
the Driver Information Centre (DIC)3 89.9 Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have thecause of this remedied
immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.
Resetting with remote control
key / manual key
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 2
3 114.
2. Wait a few minutes to allow the fuel system to be reset.
3. Turn key to position 3 to start the
engine.
If the engine does not start, repeat the
procedure.
Resetting with electronic key
system
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Insert the electronic key in the card reader 3 114.
2. Press START/STOP without
depressing any pedals.
3. Wait a few minutes to allow the fuel system to be reset.
If the engine does not start, repeat the procedure.

Refuelling 3 138.
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.
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 restarts the engine
automatically as soon as the clutch
pedal is depressed.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
134Driving and operatingSpeed limiter
Maximum speed limiter
In accordance with local or national
regulations, the vehicle may be
equipped with a fixed maximum
speed limiter that cannot be disabled.
If equipped, a warning label indicating the fixed maximum speed limit (55 to
80 mph) is located on the instrument
panel.
Deviations from the maximum speed
limit may occur briefly when driving
downhill, for physical reasons.
A warning buzzer will sound for
10 seconds every 40 seconds if the
vehicle briefly exceeds the set limit.
Vehicles also equipped with cruise
control speed limiter: the maximum
speed cannot be exceeded by
depressing the accelerator pedal
firmly beyond the point of resistance.
Cruise control speed limiter 3 131.
Parking assist
The parking assist makes reverse
parking easier by measuring the
distance between the rear of the
vehicle and obstacles. It is the driver,
however, who bears full responsibility for parking.
The system consists of four ultrasonic
parking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
An obstacle is indicated by buzzers
and, depending on vehicle, is also
indicated in the Info-Display. The
interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the distance is less than 30 cm, the
buzzer is continuous.
Notice
In versions with Info-Display
indication, the volume of the buzzer can be adjusted via the Infotainment
Driving and operating135system. Refer to Infotainment
system manual for further
information.
Deactivation
Deactivate the system by pressing
r on the instrument panel with the
ignition on. LED illuminates in the
button when deactivated. When
reverse gear is selected, no acoustic
signal will sound.
Notice
In versions with Info-Display
indication, the function can be
deactivated via the Infotainment
system. Refer to Infotainment
system manual for further
information.
The function is reactivated by
pressing r again or the next time
the ignition is switched on.
Fault
If the system detects an operating fault, when selecting reverse gear a
continuous acoustic alarm will sound
for approx. 5 seconds, a
corresponding message appears in
the Driver Information Centre (DIC)
3 89 and F illuminates in the
instrument cluster 3 85. Consult a
workshop to have the cause of the
fault remedied.Caution
When reversing, the area should
be free from obstacles which could impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.
Vehicle messages 3 90.
Basic notes on parking assist system
9 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.
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.
136Driving and operatingSpecial 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.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
the interior mirror or in the 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, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse the vehicle by only looking at the display and checkthe surrounding area behind and
around the vehicle before
reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged. An audible signal confirms
activation.
Functionality
The camera is mounted above the
rear doors/tailgate.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
