Restraint system: introduction
The restraint system reduces the risk of occu-
pants hitting parts of the vehicle interior in the
event of an accident. Furthermore, the
restraint system may also reduce the forces
exerted on the vehicle occupants when an
accident occurs.
The restraint system includes:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer the intended level of protection if all
vehicle occupants:
R are correctly wearing their seat belts.
(Y page 47)
R adjust their seat and head restraint prop-
erly (Y page 105).
The driver is also responsible for ensuring
that the steering wheel has been correctly
positioned. Observe the information relating
to the correct driver's seat position
(Y page 104).
Always ensure the air bag can inflate properly if deployed (Y page 50).
An air bag supplements a correctly fastened
seat belt and is an additional safety device
providing increased protection for vehicle
occupants in appropriate accident situations.
For example, if the protection already provi-
ded by a correctly fastened seat belt will suf-
fice, the air bags are not deployed. Further-
more, only the air bags that would increase
the degree of protection afforded to the vehi- cle occupants in the event of an accident are deployed. Seat belts and air bags generally do
not protect against objects penetrating the
vehicle from the outside.
Information on the restraint system operation can be found under "Triggering of belt ten-
sioners and air bags" (Y page 58).44

reach of children. G
WARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. G
WARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.

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)

i Read the information on qualified special-
ist workshops (Y page 29). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 151).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 95).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly. i
The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve 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.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the SmartKey has been removed in
order to dry the air-conditioning system.
The vehicle is then ventilated for 30
minutes. 138
