from striking the sensor in the rear-view mir-
ror, for instance, by luggage piled too high in
the vehicle, the mirror's automatic anti-dazzle
function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident.

on the driver's side automatically go into anti-
dazzle mode if:
R the ignition is switched on and
R incident light from headlamps strikes the
sensor in the rear-view mirror.

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. Country-specific differen-
ces are possible. Note that your vehicle
may not be fitted with all features descri-

Important safety notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Converting to symmetrical dipped
beam If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. This prevents
oncoming traffic from being dazzled. Sym-
metrical lights do not illuminate as large an
area of the edge of the carriageway.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Converting to asymmetrical dipped
beam after returning Have the headlamps converted back to asym-
metrical dipped-beam headlamps at a quali- fied specialist workshop as soon as possible
after crossing the border again. Light switch
Operation !
Switch off the side lamps and dipped-
beam headlamps when you leave the vehi-
cle. This prevents the battery from dis-
charging.
! If the battery has been excessively dis-
charged, the side lamps or parking lamps
are automatically switched off to enable
the nex tengine start. Always park your
vehicle safely and sufficiently li taccording
to legal standards. Avoid the continuous
use of the Tside lamps for several
hours. If possible, switch on the Xright
or the Wleft parking lamp. 1W
