5Window curtain airbag
The head protection window curtain airbags afford
increased protection against injuries to the head and
upper body. They inflate in the area between the A and
C pillars (see arrows) between the side windows and an
occupant’s head.Important!
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the key in steering lock to
position 1 or 2. If no fault is detected, the lamp will go
out after approximately 5 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 5 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 key is turned from steering lock
position 0 to positions 1 or 2, malfunctions in the
crash-sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 5 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Light Truck Center immediately.

Important!
The air outlets should be remain open to allow
unrestricted operation of the automatic climate control.
Notes:
For the air flow-through system to function properly, the
air vents and air outlets should be kept unobstructed.
The air outlets can be directed towards your body or
pointed upwards for draft free ventilation of the interior.

111 Automatic climate control
Te ch n i c a l

and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Automatic climate control
The automatic climate control only operates with the
engine running.
The system is always at operational readiness, except
when manually switched off.
In the automatic mode the automatic climate control
cools or heats the interior depending on outside
temperature and the selected interior temperature.
Make the temperature settings in small increments.
If the vehicle interior has been heated by direct sunlight
and is very hot, ventilate the interior (open door or
windows for a short period) before driving off
Keep the air intake grill in front of the windshield free
of debris and snow.
The air conditioning mode 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.
If the economy mode AC
OFF
is selected, the air
conditioning compressor will not engage and it is not
possible to air condition in this setting. See page 117.Notes:
The interior temperature sensor (10) should not be
touched to maintain a precise temperature.
If the vehicle travels from shade into direct sunlight, a
sensor automatically increases the air volume
temporarily to maintain the interior temperature.
The automatic climate control will not remove moisture
from the air at low outside ambient temperatures.
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.
Dustfilter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
Severe conditions (e.g. strong air pollution) may require
replacement of the filter before its scheduled interval.
A clogged filter will reduce the air volume to the
interior.

Air recirculation
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 vehicles’s interior.
To select, press briefly O button. The indicator lamp
in button lights up.
To cancel, press briefly O button again. The indicator
lamp in button goes out.
The system automatically switches from air
recirculation to fresh air, after:
•approx. 30 minutes, when the automatic climate
control switched on,
•approx. 5 minutes, when the automatic climate
control switched off.
•approx. 5 minutes, if the outside temperature is
below 45˚F (7˚C).
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.Note:
To achieve the fastest possible cooling of the interior, the
automatic climate control automatically switches to air
recirculation.
The indicator lamp in the Obutton is not illuminated
when the system automatically switches to air
recirculation.

Turn the key in steering lock to position 1.
Press buttonT. The indicator lamp in the button

•if turning the key in steering lock to position 2,
•after approx. 30 minutes,
•if the coolant temperature is too low and
•if the battery voltage drops.
Note:
The fan switches to a lower speed independent of the
setting of the air volume control.
