124Driving and operatingAdopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be used as new value for the
speed limiter.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the speed limiter is active, the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
Press MEM on the steering wheel to
request saving of the suggested
speed limit.
Press MEM on the steering wheel

operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Adaptive cruise control The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead.
126Driving and operating
Activation of the functionalitySetting speed by the driver
The adaptive cruise control has to be
switched on manually at a speed
between 30 km/h and 180 km/h. For
vehicles with automatic transmission, the automatic selector lever must be
in position D or M.
Accelerate to the desired speed and
move the thumb wheel to SET/-. The
current speed is stored and
maintained.The speed value is indicated in the
Driver Information Centre.
The preset speed can then be
changed by moving thumb wheel to
RES/+ to increase or SET/- to
decrease the speed. Move thumb
wheel repeatedly to change speed in
small steps, move and hold to change speed in large steps.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be taken over as new set speed
for the adaptive cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the adaptive cruise control is active, the recognised speed limit will be
displayed in the Driver Information Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed limit is now the new set
speed of the adaptive cruise control.
Driving and operating155The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection
The system monitors the driver's level
of vigilance at speeds above
65 km/h. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 65 km/h for
a few minutes.
System limitationsIn the following situations, the system
may not operate properly or even not
operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
● dazzle caused by headlamps of an oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roadsFuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended octane rating. A lower octane rating can reduce engine power and torque
and slightly increases fuel
consumption.
Vehicle care181After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.
If the failure continues to be
displayed, contact a workshop. The
system is inoperable when ABS or
ESC has a malfunction or a
temporary spare wheel is used. Once
the tyre has been refitted, check the
tyre pressure with cold tyres and
initialise the system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference
reference values:
1. Always ensure that all four tyres have correct tyre pressure3 210.
2. Apply parking brake. 3. Initialise the system via the Info Display 3 75.
4. Reset is confirmed by pop-up indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when: ● Tyre pressure has been changed
● Load condition has been changed
● Wheels have been swapped or exchanged
The system will not warn
instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear

data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data read documents the
technical condition of 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 uses
operating data from vehicles for
product recalls. This data can also be used to check customer warranty and
guarantee claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.Comfort and infotainment
