Safety.

Tire pressure monitoring system (TPM).

The TPM (Tire Pressure Monitoring) system displays the current pressure in the individual tyres and warns of deviations from the optimum pressure. This reduces tire wear, has a positive effect on fuel consumption and prevents dangerous tire damage.

Sideguard Assist 2.

Sideguard Assist 2 is a safety assistance system that supports the driver on both sides in critical turning situations with possibly restricted visibility. The system is intended to help the driver to detect moving obstacles within the system limits and warn the driver in order to avoid critical situations or reduce the consequences of accidents when turning off or when changing lanes.

The side areas of the vehicle are monitored. This means that vehicles, pedestrians or cyclists that could be in the blind spot are detected on both the front passenger side and the driver’s side. The radar system precisely detects the movements and warns the driver of possible collisions. The intuitive user interface and clear warnings allow the driver to drive safely and relaxed.

Electronic Stability Program (ESP®)

The Electronic Stability Program significantly reduces the risk of skidding by selectively braking individual wheels, thus preventing loss of control of the vehicle in curves and emergency steering manoeuvres.

Rain/light sensor

The rain sensor and automatic driving light are assist systems that activate automated functions by means of a sensor system and relieve the driver of routine tasks.

Acceleration Skid Control (ASR)

ASR prevents the drive wheels from spinning in two ways. On the one hand, ASR minimises wheel spinning through a measured braking intervention. On the other hand, the torque of the engine is regulated via the "electronic accelerator pedal".

Anti-lock Braking System (ABS)

The Anti-lock Braking System (ABS) supports driving stability during critical braking operations and ensures that the vehicle remains steerable. The braking forces acting on the individual wheels are distributed by the ABS so that even in an emergency braking situation no wheel is blocked for any length of time, and the steerability of the bus is largely maintained.

Active Brake Assist 6 Plus.

Emergency Brake Assist ABA 6 Plus assists the driver by automatically initiating emergency braking if there is a risk of a rear-end collision with vehicles in front or stationary obstacles. It can also detect moving or stationary pedestrians and cyclists in front of the vehicle. The system can respond with an audible and visual warning as well as automatic partial or maximum full-stop braking.

Traffic Sign Assist.

The innovative Traffic Sign Assist offers maximum safety and comfort on the road. Thanks to GPS and camera support, the vehicle speed is continuously compared with the valid traffic rules.

Frontguard Assist

Frontguard Assist is an advanced system that has been specially developed to inform the driver about people in the immediate vicinity of the front of the vehicle and to warn of an imminent accident. Whether moving off or driving slowly (up to 15 km/h), the intelligent assistant can detect potential collisions with unprotected road users.

Attention Assist 2.

Attention Assist uses a discreetly installed driver camera to detect signs of fatigue or distraction. If the system detects any irregularities in eye or lid closing behaviour, it includes you via a warning tone and display - for maximum safety on long journeys.

Automatic activation and clear instructions

Attention Assist is automatically active after the vehicle is started. Fatigue is detected from approx. 30 km/h, distraction is already detected from approx. 20 km/h. Restrictions in the function can occur due to short driving times, unfavourable lighting conditions, a covered camera or areas of the face - for example in strong sunlight, glasses, headgear or dirty lenses. In such cases, an automated message appears on the display with a cleaning instruction.
