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.
Attention assist helps you during long, monotonous journeys, such as on highways.
It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h).
If attention assist detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break.
Attention assist assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
• your personal driving style, e.G. Steering
characteristics
• journey details, e.G. Time of day and length
of journey
the functionality of attention assist is
restricted and warnings may be delayed or
not occur at all:
• if the road condition is poor, e.G. If the
surface is uneven or if there are potholes
• if there is a strong side wind
• if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
• if you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
• if you are currently using comand or
making a telephone call with it
• if the time has been set incorrectly
• in active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the multifunction display
■ activate attention assist using the onboard computer .
Symbol 1 appears in the multifunction display.
■ the attention assist: take a break! Message appears in the multifunction display. If necessary, take a break.
■ press the or
button to confirm
the message.
If attention assist is active, you will be warned no sooner than 20 minutes after your journey has begun. In addition to the message shown in the multifunction display, you will then hear an intermittent warning tone twice.
On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break and attention assist still detects increasing lapses in concentration, you will be warned again after 15 minutes at the earliest.
ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if:
• you switch off the engine.
• you take off your seat belt and open the driver's door, e.g. for a change of drivers or to take a break.
