The cabin of the Actros is built with consideration for the driver. It provides a silent, smooth and pleasant ride. Pneumatic suspension of both the cab and the tractor itself makes for a really smooth feeling even on the roughest road. The high-roof sleeper version provides two bunks (the upper one not usable while driving, as the seats must be folded). The upper bunk is somewhat wider, but all the controls (radio, windows, auxiliary heater, etc.) are available from the lower bunk. However, most of the controls one would need (auxiliary heater, sunroof, etc.) while resting doubled overhead of the driver, and the width of the upper bunk allows for a person to use them by merely stretching their hand.
The auxiliary heater can be programmed to turn on, for example, 30 minutes before the driver enters the truck, so in the winter a driver would be able to enter a warm cab instead of waiting for it to warm up.
There are large storage spaces, especially in the MegaSpace cab. Additional storage spaces are available under the lower bunk. In some cab types there are boxes behind the doors, that open from the inside, but are accessible on the outside - for storing tools, lashing belts, ratchets, etc.
The driver seat is a fully adjustable Grammer pneumatically suspended seat, and the passenger seat only allows for backrest adjustment. The steering wheel is fully adjustable as well, and allows the driver to control functions of the on-board computer as well as the built-in radio/CD player and the bluetooth phone control.
The cab has excellent sound isolation and provides almost car-like noise-levels.
The Actros cabs come in three types:
* S - designed for daily operation and construction vehicles such as cement trucks. The daily cab has its front bumper lower to the ground to prevent under-run, whereas the construction version of the S cab has its front bumper higher to prevent hitting an obstacle when driving off-road on the site.
* M - designed for distribution vehicles. It offers a sleeper, though comfort has not been focused on as in the L cab. It comes in short and long sleeper versions.
* L - Low-roof long-haul cab, providing comfortable driving and rest for the driver.
* LH "MegaSpace"- Long-haul high-roof cab, providing comfort for long driving, as well as enough space for the driver and/or passenger to freely move around the cab when needed.
The Actros comes with ASR and ABS as a standard. Also, it has load-sensing compatibility with most of the modern trailers. On the versions equipped with a digital tachograph, basic information (like current driver's working hours) are displayed on the main display. The computer's interface is very intuitive, and it is fully controllable from the steering wheel.
There is a wide range of other electronic features, offered as extras. These include lane assist (warns the driver if they inadvertently leave their lane), distance measuring radar (which engages the brakes if the vehicle in front suddenly stops), side looking radar for warning the driver about a vehicle in their blind spot, and many more, mostly oriented towards safety. All of them are marketed as "Telligent".
