Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 29). Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Conversion to symmetrical low beam 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 sym-
metrical 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.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after crossing the border again. Setting the exterior lighting
Setting options Exterior lighting can be set using:
R the light switch
R the combination switch (Y page 123)
R the on-board computer (Y page 277)

Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day- time running lamps function is required by lawin Canada. It cannot therefore be deactivated.

stationary: if you move the selector lever from a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to 0060, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to 0058, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(Y page 277).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
lamps.
i In the USA, the daytime running lamps are
deactivated upon delivery from the factory.
