ation is not high. Conversely, air bags may be
deployed even though the vehicle suffers only
minor deformation. This is the case if, for
example, very rigid vehicle parts such as longi-
tudinal body members are hit, and sufficient
deceleration occurs as a result.
If the restraint system control unit detects a
side impact or if the vehicle rolls over, the
applicable components of the restraint system
are deployed independently of each other
depending on the apparent type of accident.
R Side impact air bag and pelvis air bag on the
side on which an impact occurs, independ-
ent from the Emergency Tensioning Device
and seat belt usage
The side impact air bag on the front
passenger side deploys under the following
conditions:
- the OCS system detects that the front
passenger seat is occupied or
- the seat belt buckle tongue is engaged in
the belt buckle of the front passenger
seat
R Window curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the front-
passenger seat is occupied
R Emergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
R Window curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the
seat belt
i Not all air bags are deployed in an acci-
dent. The various air bags work independ-
ently of each other.
How the air bag works is determined by the
severity of the accident detected, especially
the vehicle deceleration or acceleration and
the apparent type of accident:
R Head-on collision
R Side impact
R Rollover Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R the hazard warning lamps are switched on
R the emergency lighting in the interior is acti-
vated
R the vehicle doors are unlocked
R the front side windows are lowered
R air-recirculation mode is activated
R climate control is switched off
R the engine is switched off and the fuel sup-
ply is cut off Children in the vehicle
Important safety notes
Accident statistics show that children secured
on the rear seats are safer than children
secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you fit
the child restraint system to a rear seat. The
child is generally better protected there.
If a child younger than twelve years old and
under 5 ft
(1.50 m) in height is traveling in the
vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R always observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's instruc-
tions.
R always observe the instructions and safety
notes on the "Occupant Classification Sys-
tem (OCS)" ( Y page 54). G
WARNING
If children are left unsupervised in the vehi-
cle, they could, in particular:
R open doors, thereby endangering other
persons or road users.
R get out and be struck by oncoming traffic.
R operate vehicle equipment and become
trapped, for example.60

Safety

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could
fog up.
To prevent the windows from fogging up:
R only switch off climate control briefly
R only switch on air-recirculation mode briefly
R for vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
R for vehicles with dual-zone automatic cli-
mate control, switch on the windshield
defrosting function briefly, if required Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
The integrated filter can filter out most parti-
cles of dust and completely filters out pollen.
In vehicles with dual-zone automatic climate
control, gaseous pollutants and odors will also
be reduced. A clogged filter reduces the air-
flow into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet. As the interval between
changes depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance
Booklet. 114

are controlled automatically. The indicator
lamp in the à switch comes on when the
function is switched on.
R Switch on the cooling with air dehumidifica-

R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or

R
If you wish to use the driver's side settings
on the co-driver's side and, for vehicles with
rear-compartment air conditioning, for the
rear compartment as well, use the "Synchro-
nization" function. The indicator lamp in the
0 button comes on when the function is
switched on.
R After long journeys, you can use the residual
heat of the engine to heat the stationary
vehicle. The residual heat utilization can
only be switched on or off while the ignition
is switched off. The indicator lamp in the
Ì button comes on when the function is
switched on.
Approximately 60 minutes after parking the
vehicle, 3-zone automatic climate control can
switch on automatically, depending on the out-
side temperature. The vehicle is then ventila-
ted for about 30 minutes at low fan setting
and 3-zone automatic climate control is dried
out. Optimum use of the rear compart-
ment air conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning
system control panel. When you switch on the
rear-compartment air conditioning, your set-
tings for temperature, airflow and air distribu-
tion are automatically adopted on the control
panel for the rear-compartment air condition-
ing.
The indicator lamp in the / button comes
on when the rear-compartment air-condition-
ing is switched on
(Y page 115).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condi-
tioning, use the control panel of the dual-zone
automatic climate control system. When you
switch on the rear-compartment air condition-
ing, you can set the temperature and airflow
separately on the control panel. The airflow
setting is automatically adopted for the rear-
compartment air conditioning. When dual-zone
automatic climate control is in à automatic
mode, the air distribution of the rear-compart-
ment air conditioning is also automatically
adjusted.
When you set the temperature and airflow of
the rear-compartment air conditioning, the indicator lamp of the / button
(Y page

116) flashes. When the rear-compart-
ment air conditioning is switched on, the indi-
cator lamp on the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on à auto-
matic mode. Only change the temperature in
small increments. Operating the climate control sys-
tem

Important safety notes When the climate control is switched off, air
intake and air circulation also stop. Only use
this setting for a brief period. Otherwise, the
windows could fog up.
