Controls in detail Climate control
The climate control is operational when- ever the engine is running. You can oper- ate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature and the current 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 mode A/C is deactivated (컄 page 182).
Warning!
Warning!
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.
When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite on unpro- tected skin in the immediate area of the air vents. Always keep sufficient distance be- tween unprotected parts of the body and the air vents. If necessary, use the air distribu- tion control (컄 page 178) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.
176
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. If the vehicle interior is hot, ventilate the interior before driving off, see “Summer opening feature” (컄 page 241). The climate control will then adjust the interior temperature to the set value much faster. Keep the air intake grille in front of the windshield free of snow and debris. Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window.

Operating the climate control system in automatic mode
Warning!
When the climate control is switched off, the outside air supply and circulation are also switched off. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.
When operating the climate control system in automatic mode, you will only rarely need to adjust the tempera- ture, air volume and air distribution. In automatic mode, cooling with dehu- midify is switched on. This function can be switched off if necessary.

Use temperature controls 2 and 3 (컄 page 175) to separately adjust the air temperature on each side of the passenger compartment. You should raise or lower the temperature setting in small incre- ments, preferably starting at 72°F (22°C). The climate control will adjust to the set temperature as fast as possible.
Increasing 왘 Turn temperature control 2 and/or
3 (컄 page 175) slightly clockwise. The climate control system will corre- spondingly adjust the interior air tem- perature.
If you turn the temperature control clockwise until it stops for one side of the vehicle, you increase the tempera- ture for the other side at the same time.
178
Decreasing 왘 Turn temperature control 2 and/or

Air conditioning
The cooling function, only operational when the engine is running, cools the vehi- cle interior down to the selected tempera- ture. The cooling function also dehumidifies the air in the vehicle interior, thus preventing the windows from fogging up.
Condensation may drip out from under- neath the vehicle. This is normal and not an indication of a malfunction.
Warning!
If you turn off the cooling function, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.

왔 Audio system Audio and telephone, operation
These instructions are intended to help you become familiar with your Mercedes-Benz audio system. They con- tain useful tips and a detailed description of the user functions.
Warning!
In order to avoid distraction which could lead to an accident, the driver should enter system settings with the vehicle at a standstill and operate the system 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 covering a distance of 44 feet (approximately 14 m) every second.
Operating safety
Warning!
Any alterations made to electronic components can cause malfunctions.
The radio, amplifier, CD changer*, satellite radio* and telephone* are interconnected. When one of the components is not opera- tional or has not been removed/replaced properly, the function of other components may be impaired.
This condition 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.

Safety precautions
Warning!
The single CD player and the CD changer* are Class 1 laser products. There is a danger of invisible laser radiation if the housing is opened or damaged. Do not open the housing. The single CD player and the CD changer* do not contain any parts that can be serviced by the user. For safety reasons, have any service work which may be necessary performed only by qualified personnel.

Warning!
In order to avoid distraction which could lead to an accident, the driver should insert CDs with the vehicle at a standstill and operate the audio system only if permitted by road, weather and traffic conditions. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your car covers a distance of 44 feet (approximately 14 m) every second.
General notes The system may not be able to play audio CDs with copy protection. Playing copied CDs may cause malfunctions during playback.
If you affix stickers to the CDs, they can become warped due to the heat that develops in the CD drive or CD changer*. In certain situations, the CDs can then no longer be ejected and cause damage to the drive. Such damage is not covered by the Mercedes-Benz Limited Warranty.
Your CD drive or CD changer* has been designed to play CDs which correspond to the EN 60908 standard. You can therefore only use CDs with a maximum thickness of 1.3 mm. If you insert thicker data carriers, e.g. ones that have data on both sides (one side with DVD data, the other side with audio data), they cannot be ejected and will damage the drive.
Controls in detail Audio system
Do not use CDs with an 8 cm diameter, not even with a CD adapter. Attempting to play CDs with an 8 cm diameter or playing such CDs with an adapter may cause damage to the CD drive. Such damage is not covered by the Mercedes-Benz Limited Warranty. Should excessively high or low tempera- tures occur while in CD changer mode*, CD ERROR will appear in the display, and the CD will be muted until the temperature has reached an acceptable level for the system to continue operation. The single CD player play audio CDs, the CD changer* can play audio CDs as well as CDs with MP3 files.

Tips on handling CDs 앫 Handle CDs carefully to prevent
interference during playback.
MP3 notes The CD changer* can play audio CDs as well as CDs with MP3 files.
앫 Avoid scratches, fingerprints and dust
on the CDs.
앫 Do not write on CDs or apply any labels
or other material to them.
앫 Clean CDs from time to time with a
commercially available cleaning cloth. Never wipe the CD in a circular motion; instead, wipe it in a straight line start- ing in the center and moving outward. Do not use solvents, anti-static sprays, etc. for cleaning.
앫 Replace the CD in its case after use. 앫 Protect CDs from heat and direct
sunlight.
Information on MP3 data carriers
CD media, CD burning software and CD writers are available in great vari- ety. Due to this variety, it cannot be guaranteed that the CD changer will be able to play every user-written CD. The burning process can lead to data errors and aging of the medium may re- sult in data loss. Therefore, the CD changer may be restricted in its ability to play MP3 data carriers; it may play them with reduced sound quality, or it may not be able to play them at all. Problems may be encountered during playback of user-written CDs with a storage capacity of more than 700 MB. These CDs do not meet valid standards as of this printing.

Compatible MP3 data carriers The CD changer can read the following data carriers in MP3 mode: 앫 CD-DA 앫 CD-R 앫 CD-RW
