establishing radio contact.
You can combine the KEYLESS-GO functions
with those of a conventional key, e.g. using
KEYLESS-GO to unlock and pressing the
& button to lock.
When locking or unlocking with KEYLESS-GO,

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are

Please note that your vehicle may

described. This also applies to safety-

Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched

on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
(Y page 221). Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the

opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries. Asymmetrical low-beam headlamps Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again.
