The new Mercedes-Benz CLS: Infotainment system: Extensive entertainment and information programme

As standard the CLS is equipped with the infotainment system Audio 20, with a 31.2 cm (12.3-inch) display and a resolution of 1920 x 720 pixels. If required this can be extended with SD card navigation, into a fully-fledged navigation system with 3D map display and dynamic route guidance with Live Traffic Information (traffic data in real time).

The features of Audio 20 include a radio with twin tuner, LINGUATRONIC voice control, a Bluetooth® interface with hands-free function for two mobile phones usable in parallel, SMS reading function and audio streaming for music transfer, two USB 2.0 connectors and an SDHC card slot. The last-named connectors are located in the compartment below the armrest in the centre console.

Audio 20 is online-capable: internet pages can be accessed while the vehicle is stationary. In addition Mercedes-Benz apps – for example to ascertain the weather conditions – can also be shown on the move.

If required Audio 20 can be extended with SD card navigation, into a fully-fledged navigation system with 3D map display and dynamic route guidance with Live Traffic Information (traffic data in real time). Live Traffic Information allows the reception of precise traffic information which is updated by the system every two minutes while driving. Taking the current vehicle location into account when requesting traffic information also ensures that the enquiring vehicles receive all the traffic information of relevance to them. The received traffic information is based on so-called "Floating Car Data" the key technology for precise acquisition of traffic data.

On request the CLS comes equipped with the infotainment system COMAND Online. This offers fast 3D hard-drive navigation with topographical map display, photo-realistic 3D buildings and 3D map rotations. The system presents its content interactively and includes features such as an animated compass.

Extensive information is shown on the navigation map, some of it provided by third-party suppliers: in addition to traffic density information it can e.g. include Car-to-X warning messages, the weather, filling stations including current fuel prices and free parking spaces.

On request a high-resolution Widescreen cockpit is available, with two 12.3-inch displays arranged beneath a shared, continuous glass cover. In the fully digital cockpit, the driver is able to feely configure the information content according to need and the driving situation. Three different styles can be selected depending on preference, mood or to suit the interior appointments. The Classic and Sport styles have a basic structure with two tubes, while the Progressive style has one central, tubular instrument.

LINGUATRONIC: Extended voice control system

LINGUATRONIC voice control has been extended to include a number of vehicle functions. Voice commands can now also be used to control the air conditioning and seat heating/ventilation, interior lighting (ambience lighting, reading lights, lighting in the rear), fragrancing/ionisation, seat massage function and head-up display. Depending on the language version and equipment level, up to 450 individual voice commands are now possible – among them e.g. commands such as "Ambience lighting violet" or "Fragrancing medium level". If the voice command is spoken without the addition of "front passenger", it refers only to the driver's side.

Also new with LINGUATRONIC 2.0: The driver is able to request a wealth of information – e.g. the next service date, the current speed limit, the remaining range or the date.

Another new feature lends a friendly, almost human touch to the voice control system of Mercedes-Benz. Initially only in the German and English versions, LINGUATRONIC uses so-called "Varying Voice Prompts", by virtue of which the system no longer responds to commands with the same acknowledgement each time, but rather with a variation and uses up to four sentences with a similar meaning.

Smartphone: wireless charging and extended messaging

The features relating to smartphone connectivity have also been expanded: With the Smartphone Integration package, Apple's smartphone-based infotainment system CarPlay™ and Google's Android Auto can be used. If a corresponding smartphone is connected by USB, the customer can, if desired, switch to the CarPlay™ or Android Auto interface.

On request mobile phones can be charged wirelessly and without a phone cradle. Wireless charging works with all mobile devices that support or can be retrofitted to support the Qi standard. The charging pad is integrated into the stowage compartment at the front of the centre console.

Front and rear passengers now have more text messaging options. They can now receive, send, forward and use voice-to-text to dictate text messages. Telephone numbers from text messages and embedded URLs can be used for further actions. Notifications appear as pop-up messages in the multimedia display.

Anti-theft alarm system: also recognises parking damage and sends a message

Another new feature is the automatic notification by text message if the vehicle suffers an impact caused by another vehicle when parked, or is towed away. The highly sensitive sensors of the optional "Anti-theft alarm system (ATA)" can detect such situations and immediately send a "push notification" message to the Mercedes me App. As soon as the customer starts the vehicle again, he/she is also informed by a corresponding message in display of the COMAND Online multimedia system. In the Mercedes me App and in the COMAND Online display, the customer is also shown when (at what time) and where (e.g. front left) the impact occurred.

In the new CLS models this optional equipment includes the new sensors and the corresponding software; the service will go live in the second quarter of 2018.

Concierge service: personal assistance

If the driver has registered and Mercedes me is activated, even the basic Mercedes me connect services can make life easier for Mercedes-Benz drivers – for example vehicle diagnostics in the event of a breakdown or accident. The Mercedes me services "Vehicle Set-Up" and "Vehicle Monitoring" allow drivers to connect to their vehicle from practically anywhere and at any time, to access vehicle information and to remotely activate a variety of functions. The range of functions includes Vehicle Tracker, Remote Door Locking and Unlocking, and Programming of Auxiliary Heating. This works both with the Mercedes me app (available for iOS and Android) and via the Mercedes me Portal (

And the new Concierge Service gives participating customers a wealth of personalised assistance: from making restaurant reservations and obtaining tips about tourist routes, to gathering information on cultural or sporting events and sending navigation destinations directly to the vehicle. Access is straightforward: registered Mercedes me connect users can establish a telephone connection with the Concierge Service in a preset language in 26 countries across Europe using either the iCall button in the overhead control panel or the Mercedes me app. The personal concierge takes care of everything else.

With the Mercedes me connect service "In-Car Office", CLS drivers can use office functions directly in the vehicle and access important data. For example, "In-Car Office" uses the locations of calendar entries and automatically transfers these to the car's navigation system. The user can also dial into a telephone conference on the basis of a calendar entry. The system can also automatically detect the required PIN access code and simultaneously dial it.
