ATTENTION ASSIST
General notes
ATTENTION ASSIST helpsy ou 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 fatigu eorincreas-
ing lapses in concentration on the part of the
driver, it suggests taking abreak.
Important safety notes
ATTENTION ASSIST is only an aid to the driver. It
might not alway srecognize fatigu eorincreasing

imately 30 minutes
Rif the road conditionisp oor, e.g. if the surface
is uneven or if there are potholes
Rif there is astrong side wind
Rif you have adopted asporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as wheny ou
change lane sorchange you rspeed
ATTENTION ASSIST is reset wheny ou continue
you rjourney and starts assessing you rtiredness
again if:
Ryou switch off the engine
Ryou take off you rseatb eltand open the driv-
er's door, e.g. for achange of drivers or to

Lane Keeping Assist
General notes
Lane Keeping Assist monitor sthe area in front of
your vehicle by means of multifunction cam-
era :which is attached behind the top of the
windshield. Lane Keeping Assist detectsl ane
markings on the road and can warn you before
you leave your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
Aw arning may be given if afront wheel passes
over alane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning
Rnot give awarning
There is arisk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
ar isk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep- ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front,f or vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncomingt raffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instancebyas ticker, in the vicin-
ity of the camera
Rthere are no or several unclear lane markings
for one lane, e.g. roadworks
Rthe lane markings are worn away,d ark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditionso n
