Volkswagen ID.4: Using assisted lane changing

When the 3-blink turn signal is activated in the Volkswagen ID.4, the vehicle can support the driver during lane changes on multi-lane highways within defined system limits, provided that sufficient space around the vehicle is detected.

Assisted lane changing in the Volkswagen ID.4 relies on the same advanced sensor systems as the Lane Change System (Side Assist) and parking assistance technologies. For this reason, it is important to carefully review all related information about Side Assist and parking systems, as well as their limitations, to fully understand how the Volkswagen ID.4 behaves in different traffic scenarios.

Requirements

Assisted lane changing in the Volkswagen ID.4 is available only under specific conditions. The vehicle must be driving forward on multi-lane highways that are included in the navigation system data, and the speed must exceed approximately 90 km/h (55 mph).

Additionally, Travel Assist must be activated in the Volkswagen ID.4, and the 3-blink turn signal function must be enabled in the vehicle settings (→ Vehicle settings menu).

Displays

Fig. 1 In the instrument cluster display: displays for assisted lane changing (general example).

1. Highlighted lane in green: assisted lane change is currently being performed in the Volkswagen ID.4. The adjacent lane is clearly marked for better visibility.
2. Directional arrows on the current lane indicate the availability and status of assisted lane changing.

• Grey: assisted lane changing is not available on that side in the Volkswagen ID.4.
• White: assisted lane changing is possible, and the neighboring lane is highlighted.

Switching assisted lane changing on and off

You can enable or disable assisted lane changing in the Volkswagen ID.4 through the Infotainment system.

1. Open the Assistance systems menu.

2. Select Travel Assist.

3. Activate or deactivate assisted lane changing as a sub-function of Travel Assist.

If a system malfunction occurs, assisted lane changing in the Volkswagen ID.4 may be automatically switched off or interrupted during operation.

If Side Assist is not available, assisted lane changing will also be unavailable in the Volkswagen ID.4.

Activating assisted lane changing

1. Press the button while driving.

Assisted lane changing is now active in the Volkswagen ID.4. The arrows displayed in the instrument cluster will initially appear in grey → fig. 1 -2-, indicating that the system is ready but awaiting suitable conditions.

Changing lanes

If the sensors in the Volkswagen ID.4 do not detect any vehicles or obstacles in the monitored area and a lane change is safe, the adjacent lane will be visually highlighted in the instrument cluster.

At the same time, the directional arrow for the selected side turns white → fig. 1 -2-, confirming that the maneuver is possible.

1. Activate the 3-blink turn signal on the desired side.

The Volkswagen ID.4 will automatically perform the lane change. A confirmation message appears in the instrument cluster, and the lane change is visually indicated → fig. 1 -1-.

During the maneuver, the Volkswagen ID.4 automatically activates the turn signal. Once the lane change is completed, the turn signal is switched off automatically.

WARNING

Assisted lane changing in the Volkswagen ID.4 does not replace driver attention and functions only within system limitations.

The system may not detect all vehicles or objects and may react too late or incorrectly. Improper use may result in accidents, serious injuries, or fatalities.

• Always check surroundings carefully before changing lanes. Fast-approaching vehicles may not be detected in time.
• Keep your hands on the steering wheel and be ready to take control of the Volkswagen ID.4 at any moment.

Deactivating assisted lane changing

1. Press the button briefly.

Or: Press the brake pedal.

Assisted lane changing and Travel Assist will be deactivated in the Volkswagen ID.4, returning full control to the driver.

Troubleshooting

Travel Assist is not available or is not functioning as expected

The yellow warning indicator appears in the Volkswagen ID.4, along with a message in the instrument cluster display.

• A malfunction in the sensor system may be present. Review the diagnostic steps for ACC and Lane Assist.
• System fault: Restart the vehicle systems.
• The system limitations may not be respected under current driving conditions.
• If the issue continues, contact an authorized Volkswagen dealer or certified Volkswagen Service Facility for professional assistance.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility for professional diagnostics and maintenance of your Volkswagen ID.4, ensuring all driver assistance systems function reliably and safely.

Take over the steering

In the Volkswagen ID.4, a white warning indicator will illuminate and a message will appear in the instrument cluster display.

This occurs when the system detects that the driver has released the steering wheel for a short period of time.

1. Place your hands back on the steering wheel and resume control of the Volkswagen ID.4 immediately.

Take over the steering immediately

A red warning indicator will appear in the Volkswagen ID.4, accompanied by a message in the instrument cluster. Depending on the situation, an audible alert will sound or the steering wheel will vibrate.

This warning is triggered when the driver has not held the steering wheel for an extended period or when the system limits of the Volkswagen ID.4 have been reached.

1. Immediately take hold of the steering wheel and take full control of the vehicle.

Comfort drive Travel Assist switches off automatically

• Vehicles without Emergency Assist: If the driver of the Volkswagen ID.4 does not hold the steering wheel for an extended time, the system will deactivate automatically.
• System malfunction or fault. Switch off the drive system of the Volkswagen ID.4 and restart it.
• If the issue persists, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

  Volkswagen strongly recommends consulting certified specialists to ensure proper system functionality in the Volkswagen ID.4.

The regulation function is canceled unexpectedly

Vehicle without assisted lane changing:

• Operating the turn signal manually may cancel the regulation function in the Volkswagen ID.4.

Assisted lane changing is not available

The yellow warning indicator lights up in the Volkswagen ID.4, and a message appears in the instrument cluster display.

• A fault in the sensor system may be present. Review troubleshooting steps related to Side Assist and parking systems.
• If the problem continues, contact an authorized Volkswagen dealer or Volkswagen Service Facility.

  Volkswagen recommends professional inspection to restore full assisted driving capabilities in the Volkswagen ID.4.

Assisted lane changing is interrupted or is not available

A corresponding message will be shown in the instrument cluster display of the Volkswagen ID.4.

• The system can no longer detect lane markings clearly.
• The driver has released the steering wheel.
• The driver applied excessive steering input against or with the system.
• The turn signal was activated repeatedly or remains engaged.
• The vehicle speed has dropped below approximately 85 km/h (53 mph).
• The Volkswagen ID.4 has detected nearby objects that prevent a safe lane change.
• The vehicle is not traveling on a multi-lane highway.

Introduction

Emergency Assist in the Volkswagen ID.4 detects driver inactivity and can actively keep the vehicle within its lane while gradually reducing speed to a stop if necessary. This function is designed to help prevent accidents or reduce their severity.

Emergency Assist system limitations

The Emergency Assist system in the Volkswagen ID.4 uses the same sensor technologies as Adaptive Cruise Control (ACC) and Lane Assist. As a result, its effectiveness depends on sensor accuracy and environmental conditions.

WARNING

Emergency Assist in the Volkswagen ID.4 is not a substitute for driver awareness and operates only within system limits.

The system may fail to detect certain situations, react too late, or behave unexpectedly. It cannot always prevent accidents or serious injuries. Careless driving may result in severe consequences, including accidents, injuries, or death.

• Always remain attentive and maintain full control of the Volkswagen ID.4.
• Follow all system limitations of ACC and Lane Assist.
• Adjust speed and distance according to traffic, weather, and road conditions.
