WARNING
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. You might otherwise drive
without the steering wheel adjustment mech-
anism being locked in position. As a result,
you could be distracted from road and traffic
conditions by an unintentional movement of
the steering wheel and thereby cause an acci-
dent.
However, the steerability of the vehicle is not
affected. Adjusting the steering wheel man-

Important safety notes
Fo rreasons of safety, Mercedes-Benzr ecom-
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. 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 side of the
road to the country where the vehicle is reg-
istered. This prevents glare to oncoming traf-
fic. Symmetrical lights do not illuminate as
large an area of the edge of the carriageway.
Convert the headlamps as close to the border
as possible before driving in these countries
(Y page 224).
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 224). If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions (Intelli-
gent Light System) are not available. Light switch
