You must also apply the brakes yourself to
avoid a collision. The DISTRONIC PLUS brakes
the vehicle in an effort to restore the preset
distance or to maintain the set speed. The
brake pedal is automatically applied as this
happens which results in the brake pedal
moving
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects stored in this area may impair pedal
movement which could interfere with the
braking ability of the DISTRONIC PLUS
system.
Do not place your foot under the brake pedal
– your foot could become caught.
GWarning!
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLUS has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.

GWarning!
The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
recognize dangers too late which could result
in an accident and serious injury to you and/
or others.
The ATTENTION ASSIST interprets your
fatigue or increasing inattentiveness
considering the following criteria:
Rthe individual driving style, for example the
way you steer
Rthe driving conditions such as time of day
and duration of the ride
The ATTENTION ASSIST function is restricted
and warnings will be delayed or not issued at
all when
Rroad conditions are bad, e.g. heavy bumps
or potholes
Rcrosswinds are strong
Rdriving in a sporty manner with high speed
in curves or rapid acceleration
Rdriving slower than 50 mph (80 km/h) or
faster than 112 mph (180 km/h) most of

be warned once more after 15 minutes at the
earliest.
During long trips, take regular and duly rests
that allow you to recover sufficiently.
