136Driving 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.
Idle speed control
To increase the idle speed, press the switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● Vehicle speed is above 0 km/h. ● Control indicator j, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 3 137.
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 3 103.9 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
3 133.
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.
Driving and operating137Resetting 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 3 133.
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 3 161.
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 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.
Switch off engine and ignition before
exiting the vehicle.
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.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 102.Deactivation
Deactivate the stop-start system
manually by pressing Î. LED in the
button illuminates to indicate
deactivation and a corresponding message appears in the Driver
Information Centre 3 103.
If deactivated manually, it is possible to reactivate the stop-start system by
pressing Î again. The LED
extinguishes in the button and a
corresponding message appears in
the Driver Information Centre. The
system is reactivated automatically
the next time the ignition is switched
on.
Driving and operating155Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed above 30 km/h.
Switching on the system
Press U. Control indicator U
illuminates yellow in the instrument
cluster.
Cruise control speed limiter function
is now in standby mode and a
corresponding message appears in
the Driver Information Centre.
Accelerate to the desired speed and
press < or ]. The current speed is
recorded.
The vehicle can be driven normally
but it will not be possible to exceed the programmed speed limit except in an
emergency.
Where the limit speed cannot be
maintained, e.g. when driving on a
steep decline, the limit speed will
flash in the Driver Information Centre
3 103, accompanied by a warning
chime.
Increase limit speed
The limit speed can be increased
continuously or in small increments
by holding down or tapping <
repeatedly.
Decrease limit speedThe limit speed can be decreased
continuously or in small increments
by holding down or tapping ]
repeatedly.
Exceeding the limit speed
In the event of an emergency, it is
possible to exceed the limit speed by
depressing the accelerator pedal
firmly beyond the point of resistance.
The limit speed will flash in the DriverInformation Centre 3 103 during this
period, accompanied by a warning chime.
Release the accelerator pedal and the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Note
In vehicles fitted with a Speed
limiter, fully depressing the
accelerator pedal will not allow you
to exceed the set maximum vehicle
speed.
Speed limiter 3 155.
Deactivation of the functionality
Press §. The speed limiter is
deactivated and the vehicle can be
driven normally.
The limit speed is stored and a
corresponding message appears in
the Driver Information Centre.
Activation of the functionality Press R. The speed limiter function is
reactivated.
Customer information229This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others the vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating data saved can be read together withthe vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed at any time.
