Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recognize
th efo llowing road users:
R Road users without lights, e.g. pedes‐
trians
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 may failto recognize other road users
with their own lighting, or may recognize
th em too late.
In these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users. #
Always obser vethe tra ffic carefully and
switch off the high beam in good time. The
Adaptive Highbeam Assist automatically
swit ches between thefo llowing settings:
R Low beam
R High beam
The sy stem de tects that vehicle lights are
approaching in the opposite direction or driving
ahead of theve hicle.
At speeds greater than 19 mp h (30 km/h), a

R If no other road users are de tected, the high
beam switches on automaticall y.At
speeds less than 16 mp h (25 km/h) or if there
is suf ficient road lighting, a change is made to

R The high beam automatically switches off.
Sy stem limitations
Ad aptive Highbeam Assist cannot take thero ad,

The de tection of obs tacles can be restricted if:
R Visibility is impaired, e.g. in fog, heavy rain or

R The sensors are dirty or co vered
Ad aptive Highbeam Assist is only an aid. You are

Fu
nction of the hot- water auxiliary hea ter
The hot-water auxiliary heater complements your
ve hicle's climate contro l system, and has a
heater boos ter,auxiliary heating and auxiliary
ve ntilation function. In addition, the auxiliary
heating sy stem heats the engine coolant topro‐
te ct the engine and sa vefuel during thewa rming-
up phase. The auxiliary heating heats the air
inside theve hicle tothe set temp erature. It is not
dependent on the heat output of theru nning
engine. The auxilia ryheating is operated directly
using theve hicle's fuel. Forth is reason, the fuel
ta nk must ha vebeen filled abo vethere ser vefuel
le ve l so that the auxiliary heating can work. The
auxilia ryheating automatically adapts its operat‐
ing mode tothe outside temp erature and
we ather. It is therefore possible that the auxiliary
heating may switch from ventilation toheating
mode or from heating toventilation mode. When
th e engine is running, auxilia ryventilation is not
acti ve.Au xilia ryheating automatically switches
itself off af ter a maximum of 50 minutes. Yo u
cannot use the "auxiliary ventilation" ope rating
mode tocool the air inside theve hicle tobelow
th e outside temp erature. Auxilia ryheating helps
to heat up theve hicle while the engine is running
and at low outside temp eratures.
Operating the hot-wa ter auxiliary heater draws
po we r from theve hicle batter y.Therefore, drive a
re asonably long dis tance af ter heating or ventilat‐
ing theve hicle twice in succession at most.
Au xilia ryheating can be activated only at temp er‐
atures below 40 °F (4.5 °C).
