2. Select neutral gear, set selector lever to N.
3. Move out of the flow of traffic as quickly as possible without
impeding other vehicles.
4. Switch off ignition.9 Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle is stationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking
assistance of a workshop 3 181.

138Driving and operatingIdle 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.
● MTA is not in N (neutral).
● Vehicle speed is above 0 mph. ● Control indicator j, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.
Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 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 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 (manual transmission) or the brake
pedal is released (manual
transmission automated).
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.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 103.
Driving and operating165Notice
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 3 164.
Deactivation of the functionality
Press $: 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.
Pressing < will also reactivate the
speed limiter function, but at the
current vehicle speed only, not the
stored speed.
Switching off the system
Press U.
Yellow control indicator U
extinguishes in the instrument cluster.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 chime may sound for
10 seconds if the vehicle briefly
exceeds the set limit.
Vehicles also equipped with speed
limiter: the maximum speed cannot
be exceeded by depressing the
accelerator pedal firmly beyond the
point of resistance.
Active emergency braking Active emergency braking can help to
reduce the damage and injury from
crashes with vehicles directly ahead, when a collision can no longer be
avoided either by manual braking orby steering. The feature uses various inputs (e.g. camera sensor, radar
sensor, brake pressure, vehicle
speed) to calculate the probability of
a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system only detects vehicles
driving in the same direction of
traffic.
After a sudden lane change, the
system needs a certain time to
detect the next preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Operation conditions
The system is operational at a vehicle
speed between 10 mph and 62 mph.
Driving and operating167System limitationsIn some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
Additionally, warning lights l and j
illuminate at the same time.
When the system detects that its
function is not available, warning
lights l or j illuminates and stays
on. Additionally, a message in the
Driver Information Centre appear.
The system may be temporarily
disrupted (for example: radar or
camera obscured by dirt, mud, snow
etc.). In this case,park the vehicle and
switch off the engine. Clean the
windscreen area around the cameraand the detection zone of the radar in the front bumper. When the warning
lights and messages still appear after starting the vehicle again, seek the
assistance of a workshop.
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 parking assist measures the
distance between the vehicle and
obstacles behind the vehicle. It
informs and warns the driver by giving acoustic signals.
256Customer informationThis 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 with the 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.
