The 12.3-inch primary display of the multimedia cockpit, interactive¹⁴² replaces the traditional instrument cluster and offers a clear display of all driving and vehicle data. It allows you to choose between two display designs. It also includes an optional navigation system, Traffic Sign Assist and Remote Online for the control of various vehicle functions via the smartphone. It is supplemented by the multi-touch display (26.5 cm/10 inches) integrated into the dashboard on the right.

The multifunction steering wheel with Touch Control buttons which features as standard in conjunction with the Multimedia Cockpit, interactive¹⁴² enhances ergonomics and ease of operation. A diverse range of vehicle systems and functions can be operated and information called up by swiping and pressing the Touch Control buttons²⁶². The Touch Control button²⁶² on the left-hand side serves to operate the primary display (instrument cluster), while the Touch Control button²⁶² on the right is used for the secondary multi-touch display.

The standard vehicle key provides visual accents and simplifies handling. In order to start the engine with the engine start-stop button, it is sufficient for the key to be in the vehicle, which means it can remain in the driver's jacket or trouser pocket while on the move. Integrated NFC technology makes it possible to start the engine problem-free even in the case of the key's battery being discharged. The optional comfort locking system offers additional comfort features and makes the legally required light check easier, for example.

In conjunction with the new convenience key, the locking system increases operating convenience and security of vehicle locking.

In addition to the legally required light check, the driver's and co-driver's doors, the side windows and the sliding sunroof can be conveniently opened and closed, or unlocked and locked, by pressing a button on the convenience key using radio remote control.

The electronic parking brake with HOLD function combines simpler handling, greater comfort and a higher level of safety. Trailer Stability Assist provides additional safety: It provides preventive stabilisation of trailers/semitrailers in potentially critical driving situations through moderate braking.

The electronic parking brake is automatically released when driving off in transmission position "D" or "R" and automatically engaged when the engine is switched off. The integrated HOLD function is activated when the vehicle is stationary – at a red light, for example – simply by depressing the brake pedal with greater force. The function is released when the accelerator pedal is depressed again. An additional function is that the parking brake is now automatically engaged if the engine is running, a door is open and the vehicle speed is 0 km/h. With the door open, it is possible for the driver to manually disengage the automatically engaged parking brake, e.g. for manoeuvring in reverse.

State-of-the-art driver support through optimum, traffic-dependent route planning. The system, with Truck Navigation for truck-specific, dynamic route guidance and live traffic information, also uses the data from the Traffic Sign Assist system and displays it on the touch display.

For its optimised route planning, the navigation system makes use of precise maps from 49 European countries. Live Traffic Information is currently available in 27 countries. Map updates can be downloaded and installed independently if required.

In conjunction with the Multimedia Cockpit, interactive, the Arocs comes as standard with an integrated radio infotainment system that conjures up a whole new feeling in the cab. A digital radio featuring Digital Audio Broadcasting (DAB) is also optionally available. Numerous connection options are available for integrating external devices.

In addition to a radio with USB port, the multimedia Touch radio is also available. The video-capable digital radio with 7" touchscreen boasts simple, intuitive operation and high sound quality – and can also be used as a navigation device, thanks to Smartphone Integration.

For easier handling and better voice quality, the Arocs can be equipped with the Convenience Telephony Plus and a mobile phone cradle.

An external telephone aerial and the integrated hands-free set with dual Bluetooth, to which up to two mobile phones can be connected, ensure perfect transmission quality. Wireless charging for smartphones of up to 6 inches (15.2 cm) via the mobile phone cradle.

The connected smartphones are operated via the multifunction steering wheel or alternatively via the multi-touch display. Connections for charging with a cable are, of course, also present.
