Switching on and off

You can check the activation status of Side Assist in the Volkswagen ID.4 via the Infotainment system and switch the function on or off as needed.

1. Open the Assistance systems menu.

2. Activate or deactivate Side Assist in the corresponding submenu.

When Side Assist is activated in the Volkswagen ID.4, the yellow indicator light in the housing of the outside mirror will briefly illuminate to confirm system readiness.

If a system malfunction occurs, Side Assist in the Volkswagen ID.4 may deactivate automatically.

Deactivation in Trailer Mode

If a factory-installed trailer hitch is used and electrically connected, Side Assist in the Volkswagen ID.4 is automatically deactivated. A notification will appear in the instrument cluster indicating that the system is unavailable while towing.

Once the trailer is disconnected, Side Assist in the Volkswagen ID.4 will automatically reactivate. For aftermarket trailer hitches, manual reactivation may be required.

Displays in the Outside Mirror

Fig. 1 In the outside mirror housing: displays of Side Assist.

flashing: a vehicle has been detected in the blind spot while the turn signal is active on that side.

lit: another vehicle is in the blind spot or is overtaking with a speed difference of up to approx. 15 km/h (9 mph).

No indicator is shown if another vehicle is passing at a significantly higher speed.

The faster another vehicle approaches the Volkswagen ID.4, the earlier the warning indicator will activate in the mirror housing.

Lane change system "Side Assist Plus"

In Volkswagen ID.4 models equipped with Lane Assist, Side Assist Plus enhances safety by providing corrective steering input in critical situations during lane changes. This function operates at both information and warning levels and works even when the turn signal is activated.

If the driver counteracts the system’s steering input, an additional warning may be provided via steering wheel vibration. This vibration feature can be configured in the Assistance systems menu of the Volkswagen ID.4.

Brightness

The brightness of Side Assist indicators in the Volkswagen ID.4 automatically adjusts according to ambient lighting conditions.

You can also manually adjust the default brightness via the Infotainment system. During adjustment, Side Assist remains inactive.

Some settings in the Volkswagen ID.4 can be stored in driver profiles and will automatically change when switching between users.
