WARNING
ARNING Risk of accident despite Adap-
tive Highbeam Assist Plus
Ad aptive Highbeam Assist Plus does not react
to:
R road users without lights, e.g. pedestrians
R road users with poor lighting, e.g. cyclists
R road users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist Plus may failto recognise other road
users with their own lighting, or may recognise
th em too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or will be
activated despite the presence of other road
users. #
Always obser vethero ad and tra1c con-
ditions carefully and switch o. the high
beam in good time. Ad
aptive Highbeam Assist Plus cann ottake into
account road, weather or tra1c conditions.
De tection may be restric ted in thefo llowing
cases:
R in poor visibility, e.g. fog, heavy rain or snow
R ifth ere is dirt on the sensors or the sensors
are obscured
Ad aptive Highbeam Assist Plus is only an aid. Yo u
are responsible for adjusting theve hicle's lighting
to the pr evailing light, visibility and tra1c condi-
tions. 140 140

Ifyo u come into contact with electrolyte,
obser vethefo llowing:
R Immediate lyrinse the electrolyte
from your skin with water and seek
medical attention.

your eyes, immediately rinse them
th oroughly with clean water and seek
medical attention.
R Ifth e electrolyte is swallo wed, imme-
diately rinse your mouth out thor-

ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times ir respecti veof whe ther the system inter-
ve nes.
The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-
mination of thero ad, highly variable shade
conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,
direct sunlight or re0ections.
R Ifth ere is dirt on the windscreen in the area of
th e multifunction camera or the camera is
misted up, damaged or obscured. R
Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because
th ey are obscured.
R Ifth e information on the navigation system's
