WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access
to an unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure themselves or have an accident with
vehicle equipment that may still be in
operation even after the SmartKey has
been removed from the ignition, such as the
seat adjustment, steering wheel
adjustment or memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if
they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very hot, and a child could be burned on these
parts.

WARNING
If a key ring is too heavy or too large, the
weight acting on the key could cause it to turn
in the ignition lock or catch on the steering
wheel. This could cause the engine to be
switched off suddenly. You may lose control
of the vehicle and cause an accident. Do not
attach any heavy or large key rings to the key
that is inserted in the ignition. General notes

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. Information about driving abroad
To convert to symmetrical low beam
when driving abroad: 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. Symmetrical lights do not illuminate
as large an area of the edge of the road.
Vehicles with Bi-Xenon headlamps
(Intelligent Light System) 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. Symmetrical lights do not illuminate as large an area of the edge
of the road.
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
asymmetrical low beam at
aqualified
specialist workshop as soo naspossible after
crossing the border and returning to the
original country.
Vehicles with halogen headlamps Switching the headlamps to symmetrical low
beam is not required in countries in which
traffic drives on the opposite side of the road
from the country where the vehicle is
registered. Legal requirements are fulfilled
even without switching. Light switch
Operation Depending on the date of manufacture of your
vehicle, the
0008or0005 symbol for the
automatic headlamp mode/daytime running
lamps is located on the light switch. Illustration: light switch with the

Important safety notes
G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a blocked filter replaced at a Mercedes-
Ben zCenter as soon as possible. G
WARNING
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
The air-conditioning system/automatic
climate control controls the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic
climate control is only operational when the
engine is running. 7
The system only works
optimally when the side windows and the roof
are closed. i
Ventilate the vehicle for a brief period
during warm weather. This will speed up the
cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
7 The residual heat function can only be activated/deactivated when the ignition is switched off. 116

until the windshield is clear again.
R Only use "air-recirculation" mode briefly,
e.g. if there are unpleasant outside odors
or when in a tunnel. The windows could
otherwise fog up as in air-recirculation
mode no fresh air is drawn into the vehicle. 118
