CAPITULO IV METODOLOGÍA
4.6. Análisis y procesamiento de datos
The climate control is operational whenev- er the engine is running. The system cools or heats the interior depending on the se- lected interior temperature and the cur- rent outside temperature.
Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system.
The air conditioning will not engage (no cooling) if the ACOFF mode is selected.

i
For draft-free ventilation, move the slid- ers for the center air ventsb to the middle position.
Warning
G
When operating the climate control, the air that enters the passenger compartment through the air vents in the footwell can be very hot or very cold (depending on the set temperature). This may cause burn or frost- bite to unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the footwell air vents. If necessary change the air flow using the air distribution controls to direct the air away from the foot- well air vents.
Warning!
G
Follow the recommended settings for heat- ing and cooling given on the following pag- es. Otherwise the windows could fog up, impairing visibility and endangering you and others.
Controls in detail
Climate control
Setting the temperature
Use temperature controls5 (컄page 103) to separately adjust the air temperature on each side of the passenger compartment. You should raise or lower the temperature setting in small increments, preferably starting at 72°F (22°C).
Increasing
왘 Turn the temperature control5 slightly upwards.
A red marking will be visible and the climate control system will correspond- ingly adjust the interior air tempera- ture.
i
The selected temperature is reached as quickly as possible.
Severe conditions (e.g. strong air pollu- tion) may require replacement of the fil- ter before its scheduled interval. A clogged filter will reduce the air volume to the interior.
If the vehicle interior is hot, ventilate the interior before driving off.
Keep the air intake grille in front of the windshield free of snow and debris.
i
If you use the standard settings for heating or cooling the passenger com- partment (컄page 102), you will rarely need to change the temperature, air volume or air distribution.
Decreasing
왘 Turn the temperature control5 slightly downwards.
A blue marking will be visible and the climate control system will correspond- ingly adjust the interior air tempera- ture.
Adjusting air volume
Use air volume control9 (컄page 103) to adjust the air volume. The following sym- bols are found on the control:
Adjusting air distribution
Use air distribution control6
(컄page 103) to adjust the air distribution. The following symbols are found on the control:

d Directs air to the footwells
a Directs air through the
center, side and rear pas- senger compartment air vents

Climate control
Air recirculation mode
Switch to air recirculation mode to prevent unpleasant odors from entering the vehicle from the outside. This setting cuts off the intake of outside air and recirculates the air in the passenger compartment.
Activating
왘 Press buttonÐ (컄page 102). The indicator lamp on theÐ button comes on.
Deactivating
왘 Press buttonÐ (컄page 102). The indicator lamp on theÐ button goes out.
The air recirculation mode is deactivated automatically:
앫 after five minutes if the outside temper- ature is below approximately 41°F (5 °C)
앫 after five minutes if the air conditioning is turned off
앫 after 30 minutes if the outside temper- ature is above approximately 41°F (5 °C)
At outside temperatures above 79°F (26°C), the system will not automatically switch back to outside air. A quantity of outside air is added after approximately 30 minutes.
Air conditioning
The air conditioning is operational while the engine is running and cools the interior air to the temperature set by the operator.
Warning!
G
When the outside temperature is below 41°F (5°C), only switch to air recirculation mode for short periods to prevent window fogging.
i
The air recirculation mode is activated automatically at high outside tempera- tures.
i
Condensation may drip out from under- neath the vehicle. This is normal and not an indication of a malfunction.
Deactivating
It is possible to deactivate the air condi- tioning (cooling) function of the climate control system. The air in the vehicle will then no longer be cooled or dehumidified.
왘 Press button± (컄page 102). The indicator lamp on the button±
lights up.
Activating
Moist air can fog up the windows. You can dehumidify the air with the air condition- ing.
왘 Press button± again (컄page 102). The indicator lamp on the ±button goes out.
The air conditioning uses the refrigerant R134a. This refrigerant is free of CFCs which are harmful to the ozone layer.
Residual heat
With the engine switched off, it is possible to continue to heat or ventilate the interior for up to 30 minutes. This feature makes use of the residual heat produced by the engine.
Activating
왘 Turn the key in the steering lock to position1or0, or remove it from the starter switch.
왘 Press buttonÐ (컄page 102). The indicator lamp on the buttonÐ
comes on.
Warning!
G
While driving, deactivate the air conditioning only temporarily to prevent window fogging.

The residual heat is automatically turned off:
앫 when the ignition is switched on 앫 after about 30 minutes

Basic settings Heater
왘 Select temperature for each side of the passenger compartment with tempera- ture controls1.
왘 Select air volume with air volume control2, set at least to position2 to prevent window fogging.
왘 Set air distribution control3 to posi- tion shown above.
왘 Turn side window defroster vents (컄page 103) to the detent position. 왘 Open center air vents (컄page 103) as
desired.
i
How long the system will provide heat- ing depends on the coolant tempera- ture and the temperature set by the operator. The blower will run at speed setting1 regardless of the air volume control setting.

Operating safety
Warning!
G
In order to avoid distraction which could lead to an accident, the driver should enter system settings with the vehicle at a stand- still and operate the systems only when road and traffic conditions permit. Always pay full attention to traffic conditions first before operating system controls while driving. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your car is cover- ing a distance of approximately 50 feet (ap- proximately 14 m) every second.
Warning!
G
Any alterations made to electronic compo- nents can cause malfunctions.
The radio, cassette deck, CD changer*, tele- phone* and voice control system* are inter- connected. When one of the components is not operational or has not been
removed/replaced properly, the function of other components may be impaired. This conditions might seriously impair the operating safety of your vehicle.
We recommend that you have any service work on electronic components carried out by an authorized Mercedes-Benz Center.
