Alike Active Brake Assist 5, Sideguard Assist – introduced exclusively by Mercedes-Benz Trucks in 2016 – can detect both stationary and moving persons and objects. Sideguard Assist provides significantly improved protection for the most vulnerable road users. The system monitors the co-driver's side and helps the driver to avoid potential collisions with cyclists, pedestrians or stationary obstacles such as traffic lights, traffic signs or lampposts when turning by providing early warnings, which leaves more time for timely braking. Tracking pattern warning on corners is active at a speed of up to 36 km/h and is therefore particularly useful in cities.

Sideguard Assist is not an automatic braking system, it rather works with a multi-stage warning process: In case a moving or stationary object is detected in the monitoring zone on the co-driver's side, the driver initially receives a visual warning. A warning triangle lights up in the MirrorCam display on the co-pilot's side. If there is a risk of collision, an additional visual and audible warning is triggered: The display flashes red multiple times and then appears permanently red after two seconds. In addition, a warning tone sounds simultaneously on the co-driver's side. The system also supports the driver in avoiding potential collisions when changing lane at speeds of up to 90 km/h.

Centrepiece of Sideguard Assist are two short-range radar sensors at the frame in front of the truck's rear axle on the co-driver's side. The side monitoring zone has a width of 3.75 m. The system is configured to cover the length of the whole tractor/trailer combination, plus 2 m in front of the vehicle and up to 1 m behind it. It works for rigid vehicles as well as for complete tractor/trailer combinations up to 18.75 m in length.

New Active Brake Assist 5 is an enhancement of Active Brake Assist 4. This safety assistance system is unique in terms of its functionality and no other manufacturer provides a system alike. With the improved fifth generation of Active Brake Assist, Mercedes-Benz is also underlining its leading position when it comes to the safety of heavy-duty trucks – a role that is continually reaffirmed by market demand. Since Active Brake Assist 1 was introduced in 2006, Mercedes-Benz Trucks has sold nearly 230 000 trucks with the emergency braking system on-board.

New for Active Brake Assist 5 is its functionality based on the radar and camera system. Among other features, it is now able to respond to people at speeds of up to 50 km/h. Within system limits, Active Brake Assist 5 can respond to a person who is crossing in front of the vehicle, coming towards it or in the same lane by applying maximum braking power up to standstill. The same applies to pedestrians who unobservantly walk in front of the vehicle and who may become paralysed – a situation which is happening more and more often in this smartphone age.

If Active Brake Assist 5 detects the threat of a rear-end collision with a vehicle in front, with a stationary obstacle or a pedestrian who is crossing in front, coming towards the vehicle or in the same lane, a three-stage warning system makes the driver aware of the threat. If the driver does not take action independently, a visual and audible warning is given first. After this, brake application of approximately 3 m/s is initiated, corresponding to around 50 percent of the maximum braking power. If the driver still hasn't responded, the system initiates maximum braking power – if necessary to a standstill – and activates the hazard warning lights at speeds below 50 km/h to warn the traffic behind. When at a standstill, the new electronic parking brake is applied automatically.

Active Brake Assist 5 supports the driver in critical driving situations and, in optimal conditions, can help to mitigate the effects of accidents or even avoids them. The driver, however, as the person in control of the vehicle, is at all times responsible for the entire process of driving and cannot rely exclusively on the safety assistance systems.
