Driving and operating153Accelerate to the desired speed and
move thumb wheel briefly to SET/-.
The current speed is stored as
maximum speed.
The preset maximum speed can be
changed by moving thumb wheel to
RES/+ to increase or to SET/- to
decrease the desired maximum
speed. Move thumb wheel repeatedly
to change speed in small steps, move
and hold to change speed in large
steps.
Speed value is indicated in the Driver
Information Centre.
Press Ñ to activate speed limiter.
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 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.
Press MEM on the steering wheel to
request saving of the suggested
speed limit.
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 3 100.
Exceeding the speed limit
In the event of an emergency, it is
possible to exceed the speed limit by
depressing the accelerator pedal
firmly. 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.
154Driving and operatingDeactivation of the functionality
Press Ñ, speed limiter is in pause
mode and a message is displayed.
The vehicle is driven without speed
limiter.
Speed 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 the system
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 limit recognition may not
operate correctly if traffic signs do not comply with the Vienna Convention
on Road Signs and Signals.
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 preceding vehicle directly
ahead, in your path.
If a vehicle directly ahead is
approached too quickly, a warning
chime and alert in the Driver
Information Centre is provided.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.
Activation
Forward collision alert detects
vehicles and operates automatically
at all speeds above 3 mph and
53 mph. The system detects
stationary vehicles if the speed does
not exceed 50 mph.
174Driving and operatingSystem limitations
The system performance may not operate properly when:
● Vehicle speed is below 37 mph.
● Driving on winding or hilly roads. ● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign items, e.g.
stickers.
● The sun is shining directly into the camera lens.
● Close vehicles ahead.
● Banked roads.
● Road edges.
● Roads with poor lane markings.
● Sudden lighting changes.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of thedriver 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 3 100
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 40 mph. 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 40 mph).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
208Vehicle careSystem 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 240.
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).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
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Customer information249● Faults and defects in importantsystem 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.
