Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously
with an acoustic alert if the driver has
not taken a break after 2 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 if one of the following conditions is met:
● The vehicle has been stationary for more than 15 minutes with the
engine running.
● The ignition has been switched off for a few minutes.
● The driver's seat belt has been unfastened and the driver's door
is open.
Note
If the vehicle speed drops below
65 km/h, the system is paused. The
driving time is counted again once
the speed is above 65 km/h.
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 thedriver, 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 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.
234Vehicle care1. Always ensure that all four tyreshave correct tyre pressure
3 265.
2. Apply parking brake.
3. Initialise the deflation detection system: If the vehicle has a
graphic info display, press F for
three seconds. If the vehicle has a
colour info display, the
initialisation is done in the vehicle
personalisation 3 118.
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 information273Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● 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
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
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 (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
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 which is read out,
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
functions
Comfort settings and custom settings can be stored in the vehicle and
changed or reset at any time.
Depending on the equipment level in
question, these include
● seat and steering wheel position settings
● chassis and air conditioning settings
● custom settings such as interior lighting
You can input your own data in the
infotainment functions for your
vehicle as part of the selected
features.
Depending on the equipment level in
question, these include
● multimedia data such as music, videos or photos for playback in
an integrated multimedia system
● address book data for use with an
integrated hands-free system or an integrated navigation system
