rlighting Important safet
ynotes
For reasons of safety, Mercedes-Ben zrecom-
mends that you driv ewith the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirement sand self-imposed obli-
gations. In these countries, the daytime driv-
ing lights are automatically switche donwhen
the engin eisstarted. Notes on driving abroad
Converting to symmetrical dipped beam
when drivin gabroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the countr ywhere the vehicle is reg-
istered. This prevents oncomi ngtraffic from
being dazzled .Symmetrical lights do not illu-
minate 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 206).
Converting to asymmetrica ldipped beam
after retu rning: conver tthe headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 206).

the headlamps are converted to symmetrical
dipped beam, not all light functions are avail- able. "Motorway mode" and the "extended
range foglamps" are deactivated. Light switch

General driving tips
Rolling with the engine switched off G
Risk of accident
Never switc hthe engin eoff while the vehicle
is in motion.
There is no powe rassistanc efor the steering
and the service brake when the engin eisnot
running.
You will require considerably mor eeffort to
steer and brak eand you could therefore lose
control of the vehicl eand cause an accident. Engine oil
! Vehicle swithadiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or countr yroads for 20 minutes
at least ever y500 km. Appl

Important safet ynotes G
Risk of accident
Do not change down for additional engine
brakin gona slipper yroad surface. This could
cause the driv ewheels to lose their grip and
the vehi clec ould skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towin gatrailer,
you must shift to alower gear in good tim eor,
on vehicles wit hautomatic transmission,
select shift range 1,2or 3.
i This also applie sifyou have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLU S.
This will use the brakin geffect of th eengine,
so les sbraki ngwill be required to maintain
the speed .This relieves the load on the brake
syste mand prevent sthe brake sfrom ove r-
heati ngand wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. 154
