Overview of climat ec ontrol systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preven tt he windows from fogging up:R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engin eisr unning. Optimum operation is only
achieved with the side windows and roof closed.
i When the weather is warm, ventilate the
vehicle for ab rief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Ac logged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway so bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e .g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.102

air inside th ev ehicle is cooled and dehumidified
according to th et em peratur es elected.

Problems with the "Cooling with air dehumidification" function Problem
Possible causes/consequences and P Solutions
The indicator lamp in the

flashes three times or
remains off. The "Cool-
ing with air dehumidifi-
cation" function cannot
be switched on. Cooling with air dehumidification has been deactivated due to am al-
function. X
Visit aq ualified specialist workshop.
Setting climate control to automatic
General notes Automatic mode is only available with dual-zone
automatic air conditioning.
In automatic mode, the set temperature is main-
tained automatically at ac onstant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The automatic mode functions optimally when
the "Cooling with air dehumidification" function
is activated. If necessary, cooling with air dehu-
midification can be deactivated.
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified .T he windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The indicator lamp on

The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.

General notes If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

General notes The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutesafter the engine has
been switched off. The heating time depends on
the set interior temperature.

G WARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool dow na nd
thoroughly clea nt he engine oil off the com-
ponents before starting the engine.
H Environmental note
When adding oil ,t ake care not to spil la ny. If
oil enters the soil or waterways, it is harmfu lt o
the environment.
! Only use engine oil sa nd oil filters that have
been approved for vehicles with as ervice sys-
tem. You can obtai nal ist of the engine oils
and oil filters tested and approved in accord-
ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service center.
Damag etot he engine or exhaust system is
caused by the following: R
using engine oil sa nd oil filters that have not
been specifically approved for the service
system R
replacing engine oil and oil filters after the
interval for replacement specified by the
service system has been exceeded R
using engine oil additives.
! Do not add too much oil .Ift he oil leve li s
above the "max" mark on the dipstick, too
much oil has been added. This can lea dt o
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
Example :e ngine oil cap X
Turn cap C counter-clockwise and remove it. X
Add engine oil.
If the oil leve lisatorb elow the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 liter) of
engine oil. X
Replace cap C on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely. X
