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.
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.

Important!
This vehicle is equipped with an air conditioning
system that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

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.
The system will not heat or cool any quicker 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. Make the temperature
settings in small increments.
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 AC
OFF
selected, see page 178. Notes:
The current settings (Temperature, Air volume, AC
OFF,
Activated charcoal filter, ON / OFF) are stored for each
electronic key before the electronic key is removed from
the starter switch or when the vehicle is locked using
the KEYLESS-GO-card (vehicles with keyless-go), see
key dependent memory settings on page 113.
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 180 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 AC
OFF
cannot be switched off.
Have the air conditioner checked by a Mercedes-Benz
Center should this happen.
If the vehicle interior has been heated by direct sunlight
and it is very hot, ventilate the interior (open door or
windows for a short period) before driving off.

cluster displayPractical hints Car care Index Basic setting – automatic mode
In the automatic mode the automatic climate control
cools or heats the interior depending on the direction
and strength of the sunlight, outside temperature,
selected interior temperature and the actual interior
temperature of the vehicle. With the automatic climate
control switched off, the air volume and distribution can
still be set manually.
There are three basic settings for the automatic mode:
•Automatic air volume control
•Automatic air outlet control, left and right
•Automatic air outlet control, center, see page 169
We recommend these settings to be used all year round.Air volume and distribution are controlled
automatically.
We recommend to set the temperature switches on the
left and right to 72
°F (22
°C). Please make changes from
this setting to suit your personal requirements.
Automat ic airf low regu lation:
Press the A on the air volume switch. The display
shows “AUTO”.
Automatic air distribution:
Press on both Uknobs until they click in. Theh,
jand ksymbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.

An activated charcoal filter markedly reduces bad odors
and removes pollutants from air entering the passenger
compartment.

The system switches automatically to the air
recirculation mode, if the carbon monoxide (CO) or
nitrogen oxides (NO
X) concentration of the outside air
increases beyond a predetermined level.
The automatic air recirculation mode does not function
if economy mode ACOFF
is selected or if the outside
temperature has fallen below 40
°F(5
°C).
