Volkswagen ID.4: Functions of the proactive passenger protection system

Basic functions

In critical driving situations, the following functions may be initiated either individually or jointly, e.g. in the case of an emergency braking maneuver, if the driver understeers or oversteers or in the event of non-serious collisions:

• Reversible belt tensioning of the fastened safety belts for the driver and front passenger.
• Depending on the vehicle equipment, automatic closing function for the side windows that leaves them open only a crack.
• Activating the emergency flashers.

Depending on the critical driving situation, the safety belts may be tightened individually or together.

Additional functions for vehicles with Autonomous Emergency Braking (Front Assist)

On vehicles with Autonomous Emergency Braking (Front Assist), the probability of a collision with the vehicle in front is also calculated within the limits of the system. If the system detects that a rear-end collision is likely or initiates heavy braking, this can trigger the proactive passenger protection system.

Additional functions for vehicles with Emergency Assist

On vehicles with Emergency Assist, the proactive passenger protection system can be triggered if driver inactivity is detected.

Depending on the activation level, the following functions are triggered:

• Brief or permanent reversible belt tensioning of the engaged driver's safety belt.
• Depending on the vehicle equipment, automatic closing function for the side windows that leaves them open only a crack.

Setting in the Driving Mode Selection

On vehicles with Driving Mode Selection, the proactive passenger protection system is adapted to the special vehicle setup of the driving mode.
