ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid to the driver. It
might not always recognize fatigue or increasing
inattentiveness in time or fail to recognize them
at all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all:
if the length of the journey is less than approx-
R
imately 30 minutes
if the road condition is poor, e.g. if the surface
R
is uneven or if there are potholes
if there is a strong side wind
R
if you have adopted a sporty driving style with
R
high cornering speeds or high rates of accel-
eration
if you are predominantly driving slower than
R
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
if you are driving with the Steering Pilot of
R
Distance Pilot DISTRONIC activated
if the time has been set incorrectly
