The system can display the following (vertical) traffic signs where identified.▶ Speed limit.
▶ Overtaking prohibited.
Additional signs, such as 'when wet' or signs which only apply for a limited
time can also be displayed.
The system displays only traffic signs that are in the “viewing area” of the sen-
sor » Fig. 267 .
Data from the sensor is supplemented by information from the Infotainment
Navigation. This is the reason why traffic signs with maximum speeds can also
be shown on sections of roads which do not have any traffic signs.

cialist garage.
System limitation (Navigation data not available)
If the Infotainment Navigation submits no data, a message regarding the limi- tation of the system function appears. Check whether the map documents are
up to date or whether the vehicle is currently in a location for which no naviga-
tion data are available.
Traffic signs unavailable
No speed restriction is detected, a message is displayed regarding the unavail-
ability of road signs.
Fatigue detection
The fatigue detection system (hereinafter referred to as system) recommends
the driver takes a break from driving when driver fatigue can be detected due
to the driver's steering behaviour.
From the starting of the journey, the system evaluates the steering behaviour
at speeds 65-200 km/h. If, while driving, there have been changes in the steer-
ing behaviours that are evaluated by the system as indicating possible fatigue,
a break recommendation is issued.
Conditions under which a break from driving is detected by the system ▶ The vehicle is stopped and the ignition is turned off.
▶ The vehicle is stopped, the seat belt is taken off and the driver's door is
opened.
▶ The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
The system can be activated/deactivated in the Infotainment menu

WARNING■The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
For the driving ability is always the driver's responsibility. Never drive if
you feel tired.
■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Storing the tyre pressure values and Infotainment display
229
The tyre pressure monitoring function (hereinafter referred to as the system)
monitors the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light
lights up in the in-
strument cluster and an audible signal sounds » page 35.
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
The tyre pressure values are always stored in the system if one of the fol-
lowing events occurs.
▶ Change of tyre inflation pressure.
▶ Change one or more wheels.
▶ Change in position of a wheel on the vehicle.
▶ The warning light
lights up in the instrument cluster.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre inflation pressure must be checked regularly » page 261.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
■
Before storing the pressure values, the tyres must be inflated to the
specified inflation pressure » page 261. If incorrect pressure values are
saved, the system may also not issue a warning even if the tyre inflation
pressure is too low.
CAUTION
To ensure proper system function, the tire pressure values must be stored ev-
ery 10 000 km or 1x a year.

Operating in winter conditions
All-year (or “winter”) tyres
All-year or “winter” tyres (indicated by an M+S or a mountain peak/snowflake
symbol ) to improve the performance of the vehicle in winter conditions.
To get the best possible driving characteristics, all-year or “winter” tyres, with a minimum tread depth of 4 mm on all four wheels, should be fitted.
If “winter” tyres are mounted, summer tyres should be fitted again in good
time as they provide better handling properties, a shorter braking distance,
less tyre noise and reduced tyre wear on roads which are free of snow and ice
as well as at temperatures above 7 °C.
Speed symbol
All-year or “winter” tyres (marked with M+S and a peak/snowflake symbol
)
of a lower speed category than listed in the vehicle’s technical documentation
can be used provided that the maximum permissible speed for these tyres is
not exceeded even if the maximum possible speed of the vehicle is higher.
The speed limit for all-season or “Winter” tires can be adjusted in the infotain-
ment menu

Tyres
.
If the vehicle has all-season or “winter” tires of a lower speed category then
the specified maximum speed of the vehicle (referring to tyres that have not
been delivered by the factory, a warning label with the maximum value of the
speed category provided for the mounted tyres must be fixed in the interior of
the vehicle in a constantly visible place in the driver’s field of vision. The warn-
ing label (sticker) can be replaced by setting the maximum value of the speed
category supplied for the mounted tyres in Infotainment 1)
. This specification
defines the maximum vehicle speed with mounted all-season or “winter”tyres
that may not be exceeded.
Snow chains
The snow chains improve handling in wintry road conditions.
