tion Assist is adapted accordingly and the
driver is warned earlier.

happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.

Traffic Sign Assist

General notes
Traffic Sign Assist displays the maximum
speed permitted to the driver in the instru-
ment cluster. The data and general traffic reg-
ulations stored in the navigation system are
used to determine the current speed limit.
As Traffic Sign Assist is a map-based system,
traffic signs put up temporarily (e.g. near
roadworks) are not detected.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits is
updated.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are
also shown.
The traffic signs are only displayed with the
restrictions if:
the regulation must be observed with the
R
restriction, or
Traffic Sign Assist is unable to determine
R
whether the restriction applies
