71 Restraint systems
Technical
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index The following system components are monitored or
undergo a selfcheck: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from steering
lock position 0 to position 1 or 2, malfunctions in the
crash-sensors 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 236 for information on the Supplemental
Restraint System (SRS) indicator lamp.
Wa r n i n g !
In the event a malfu nction of th e “SRS” is indic ated
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.

Coolant temperature gauge (3)
During severe operating conditions and stop-and-go city
traf f ic, th e coola nt tempera ture may rise close to th e red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.Outside temperature indicator (5)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaption to ambient temperature takes place in steps
and depends on the prevailing driving conditions
(stop-and-go or moderate, constant driving) and amount
of temperature change.
Wa r n i n g !
• Driving when your engine is badly overheated
can cause some fluids which may have leaked
into the engine compartment to catch fire. You
could be seriously burned.• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

6Display and controlsThe 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 h eat or cool a ny quicker by setting a
higher or lower temperature.
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 desired interior temperature can be selected
separately for the left and right side of the passenger
compartment.

temperature setting of 72°F.
QAir volume and distribution are controlled
automatically.
This setting can be used all year around.
Economy
The function of this setting corresponds to the
automatic mode. However, because the air conditioning
compressor will not engage (fuel savings), it is not
possible to air condition in this setting.
Press S button to activate.

This mode can be selected to temporarily reduce the
entry of annoying odors or dust into the vehicle’s
interior.
Outside air is not supplied to the car’s interior.
To select, press O button.
To cancel, press O button again.
The system will automatically switch from recirculated
air to fresh air
•after approximately 5 minutes at outside
temperatures below approximately 40°F (5°C),
•after approximately 30 minutes, at outside
temperatures above approximately 40°F (5°C),
•after approximately 5 minutes, if button S is
pressed.
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
At high outside temperatures, the system automatically
engages the recirculated air mode thereby increasing
the cooling capacity performance, switching to partially
fresh air within 20 minutes.Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.

Activated charcoal filter
An activated charcoal filter markedly reduces bad odors
and removes pollutants from the air entering the
passenger compartment.
To select, press e button.
To cancel, press e button again.
The blower speed is slightly increased to supply a
constant volume of air.
The system switches automatically to the air
recirculation mode, if the carbon monoxide (CO) or
nitric oxide (NO
X) of the outside air increases beyond a
predetermined level.
When pressing button P or S, the filter is also
switched off.
Notes:
The automatic air recirculation does not function when
selecting the Economy mode S, or the outside
temperature is below 45°F (7°C).
The activated charcoal filter should be switched off
when windows fog up on the inside, or if the passenger
compartment needs to be quickly heated or cooled
down.Residual engine heat utilization
With the engine switched off, it is possible to continue
heating the interior for a short while.
Air volume and distribution are controlled
automatically.
To select:
Turn electronic key in steering lock to position 1 or 0 or
rem ove electronic key. Close a ir outlet in rear passenge r
compartment.
Press T button.
This function selection will not activate if the battery
charge level is insufficient.
To c a n c e l :
Press T button.
The system will automatically shut off
•If you turn electronic key in steering lock to
position 2,
•after approximately 30 minutes,
•if the battery voltage drops.
