Driving and operating155ActivationSetting speed by the driver
Press toggle switch once briefly to
RES/+ or SET/- .
Following the preset speed can be set by pressing toggle switch to RES/+ to
increase or SET/- to decrease the
desired maximum speed. Short press
changes preset speed in small steps, long press in large steps. Speed
value is indicated in the Driver
Information Centre.
Press Ñ to activate speed limiter.
Adopting speed by the traffic sign
assistant
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the traffic sign
assistant. If the speed limiter is active,
the recognised speed limit will be
displayed in the Driver Information
Centre and "MEM" illuminates.
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 is the new value for the
speed limiter.
This function can be deactivated or activated in the personalisation
menu, 3 103.
Exceeding the speed limit
In the event of an emergency, it is possible to exceed the speed limit by
a "kickdown". In this case the preset
speed value flashes.
Release the accelerator pedal and
the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation Press Ñ: speed limiter is in pause
mode, Pause is indicated. The
vehicle is driven without speed limit.

156Driving and operatingSpeed limiter is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.
Resume limit speed Press Ñ. The stored speed limit will
be obtained.
Switching off
Press ß, the speed limiter mode is
deselected and the speed limit
indication extinguishes in the Driver
Information Centre.
Pressing m to activate cruise control
deactivates speed limiter.
The preset speed remains in the
memory when the ignition is switched
off.
Fault
In the event of a speed limiter fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limiter may not operate
correctly if traffic signs do not comply with the Vienna Convention on RoadSigns and Signals (Wiener
Übereinkommen über
Straßenverkehrszeichen).
Forward collision alert The forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen to
detect a vehicle directly ahead, in
your path.
The system triggers different level of
alerts depending on the risk of
collision detected. The alerts are
displayed in the Driver Information
Centre.
Level 1: A visual alert is displayed.
Level 2: A visual alert is displayed and an audible alert sounds.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.

176Driving and operatingDriver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time alert combined with driver drowsiness detection.9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. It is recommended that
you take a break as soon as you
feel tired or at least every two
hours. Do not take the wheel if you are tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 103
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert
The driver gets notified by a pop-upreminder symbol € in the Driver
Information Centre simultaneously with a acoustic alert if the driver has
not taken a break after two hours of
driving at a speed above 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The 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. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly
suited to fast roads (speed higher
than 65 km/h).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the firstlevel 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 limitations In 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.

208Vehicle careIn this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 94.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise 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 road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
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 239.
2. Apply manual parking brake.
3. Press w to reset deflation
detection system.
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 depthCheck 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).
