Proactive occupant protection system
The proactive occupant protection system is an assistance system that initiates action to protect
vehicle occupants in dangerous situations. However, the system cannot prevent a collision.
The full scope of functions for the proactive occupant protection system will be available only if
the function has been activated in the Infotainment system and there are no malfunctions.
Basic functions
Depending on country-specific legal requirements and also on the vehicle equipment level, the
following functions may be initiated, either singularly or jointly, in critical situations (e.g.
emergency braking or over or understeering) as of a speed of approximately 30 km/h (19 mph):
—Reversible belt tensioning of the fastened driver and front passenger seat belts.
—Automatic closing of the side windows leaving only a narrow gap.
The belts may be tensioned individually or together depending on the respective critical driving
situations.
Additional information for vehicles with an area monitoring system
(Front Assist)
In vehicles fitted with the area monitoring system (Front Assist), the probability of a collision
with the vehicle ahead is also calculated within the system limits. The system can trigger the
proactive occupant protection system if it detects a probable collision or initiates strong braking.
Settings in the Infotainment system
Depending on the vehicle equipment, settings for the proactive occupant protection system with
the full range of functions can be adjusted in the Infotainment system.
