Important safety notes

ATTENTION ASSIST helps you during long, monotonous journeys such as on freeways and interstate 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.

WARNING
ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentration too late or not at all. It is not a substitute for a well-rested and attentive driver.

Fatigue may cause you to recognize hazardous situations too late, misjudge a situation or react more slowly. For this reason, make sure you feel rested before you begin driving and during your journey. Make sure that you take regular breaks in time, particularly on long journeys. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

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
 - driving conditions, e.g. time, driving time 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 predominantly drive at speeds under 50 mph (80 km/h) or over 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
