TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed
for use with the Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are required for
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the
passenger front airbag will not deploy.
The 7 indicator lamp located on the center console
will be illuminated, except with electronic key removed
or in starter switch position 0. The system does not
deactivate the door mounted side impact airbag.
Self-test BabySmart
TM without special child seat
installed
After turning electronic key in starter switch to
position 1 or 2, the 7 indicator lamp located on the
center console comes on for approximately 6 seconds
and then extinguishes.
If the indicator lamp should not come on or is
continuously lit, the system is not functioning. You must
see an authorized Mercedes-Benz Center before seating
any child on the front passenger seat. See page 302 for
notes on the 7 indicator lamp.

Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the 7 indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.

approximately 4 seconds or if it comes on thereafter, a
malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from starter
switch position 0 to position 1 or 2, malfunctions in the
crash sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 4 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.Note:
See page 299 for information on the Supplemental
Restraint System (SRS) indicator lamp.
The driver and passenger front airbags are designed to
activate only in certain frontal impacts exceeding a
preset threshold. The front passenger airbag deploys
only if the front passenger seat is occupied and the
7 indicator lamp on the center console is not
illuminated.
Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz Center
immediately to have the system checked; otherwise the
“SRS” may not be activated when needed in an
accident, which could result in serious or fatal injury,
or it might deploy unexpectedly and unnecessarily
which could also result in injury.

cluster displayPractical hints Car care Index Automatic climate control
The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
Th e system w il l not hea t or c ool a ny q uicker by setting a
higher or lower temperature.
The desired interior temperature and air distribution
can be selected separately for the left and right side of
the passenger compartment.
The automatic climate control removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
The air conditioning will not engage (no cooling) if the
economy mode S is selected, see page 173. Notes:
Do not obstruct the air flow by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 175 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode S cannot be switched off. Have
the air conditioner checked by a Mercedes-Benz Center
should this happen.
Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.

Press button 0. The display shows “0”.
The fresh air supply to the vehicle interior is shut off.
While driving, use this setting only temporarily,
otherwise the windshield could fog up.
To s wi tch o n :
Press button 0 or P or at least one of the U
buttons so that it pops out and then click it back in. Front center console storage compartment
ventilation
The front center console compartment has its own air
outlet.
To open: Slide the lever up.
To close: Slide the lever down.
The air volume is dependent on the setting of:
•air distribution control,
•air volume control,
•air outlets in the dashboard.
The air temperature is about the same as that of the
dashboard air outlets. It cannot be regulated separately.
Note:
The compartment can get very warm due to its confined
space. When storing heat sensitive objects in the
compartment, close the air outlet while heating the
passenger compartment.
Do not allow articles to obstruct the air outlet in the
storage compartment.
