ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST helps yo uduring long,
monotonous journeys, such as on highways .Itis
active in the rang ebetween 50 mph (80 km/h)
and 112 mph (180 km/h).
If ATTENTION ASSIST detects typica lindicators
of fatigueori ncreasing lapsesinc oncentration
on the part of the driver, it suggests yo utake a
break.
ATTENTION ASSIST assesses your level of fati-
gueorl apsesinc oncentration by taking the fol-
lowing criteria into account:
Ryour personald riving style, e.g. steering char-
acteristics
Rjourney details, e.g. time of daya nd length of
journey The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occurata
ll:
Rif the roadc ondition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is astrong sid ewind
Rif yo uhavea doptedas porty driving styl ewith

ATTENTION ASSIST is only an ai dtothe driver. It
might not always recognize fatigueori ncreasing
inattentiveness in time or fai ltorecognize them
at all. The system is not asubstitute for awell-
resteda nd attentive driver.

Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter coul dbe
damaged by the non-combusted fuel.
If the indicator/warning lamp sdonot light up at low temperatures, it is very likelyt hat the dis-
