tries, operation of the headlamps varies due
to legal requirement sand self-imposed obli-
gations. Notes on driving abroad
Convert to symmetrical dipped beam
when driving abroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite sid eofthe
roa dtot he country wher ethe vehicle is reg-
istered. This prevents glar etooncoming traf-
fic. Symmetrical lights do not illuminate as
large an area of the edg eofthe carriageway.
Convert the headlamps as close to the border
as possible before drivin ginthese countries
(Y page 24 7).
Convert to asymmetrical dipped beam
after returning: convert the headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 247).

cal dipped beam, the "motorway mode" and "extended range foglamps" function
