Controls in detail Automatic climate control

The automatic climate control is operation- al whenever the engine is running. You can operate the automatic climate control sys- tem in either the automatic or manual mode. The system cools or heats the inte- rior depending on the selected interior temperature and the current outside temperature.

Warning!

When operating the automatic 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 frost- bite on unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 201) to direct the air to air vents in the vehicle inte- rior that are not in the immediate area of un- protected skin.

202

Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system.

Warning!

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 and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Center.

The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 210).

Warning!

Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others.

i Keep the air intake grille in front of the wind- shield free of snow and debris. Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window.

i If the vehicle interior is hot, ventilate the in- terior before driving off, see “Summer opening feature” (컄 page 253). The automatic climate control will then adjust the interior temperature to the set value much faster.

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 necessary ser- vice work performed only by qualified personnel.

Controls in detail Audio system

Warning!

In order to avoid distraction which could lead to an accident, the driver should insert CDs with the vehicle at a standstill and oper- ate 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 be- come 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 de- signed 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.

Do not use CDs with an eight cm diameter, not even with a CD adapter. Attempting to play CDs with an eight cm diameter or playing such CDs with an adapter may cause damage to the CD drive. Such dam- age 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.

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.

MP3 notes The CD changer* can play audio CDs as well as CDs with MP3 files.

Information on MP3 data carriers

i CD media, CD burning software and CD writers are available in great variety. 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 result 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

Compatible file systems and compres- sion methods Use Romeo or Joliet. Depending on file format used, up to 128 characters are possible The following compression methods are compatible: 앫 MP3
앫 WMA 앫 WAV

Compatible bit and sampling rates Fixed and variable bit rates of up to 320 kBit/s are possible. The following table lists possible sampling rates:

230

MPEG1
Audio Layer 3
