Volkswagen ID.4: Warning signs for the high-voltage system

Where can warning signs be attached?

• On covers and protective caps that conceal high-voltage components in the Volkswagen ID.4.
• Directly on all high-voltage components, including the high-voltage battery.
• Inside the hood area of the Volkswagen ID.4.

Warning signs

The appearance of warning labels may vary slightly depending on production version, but all indicate critical safety information related to the high-voltage system of the Volkswagen ID.4.

1. Exposure to high voltage in the Volkswagen ID.4 can result in severe injury or death. Never touch battery terminals with hands, tools, or conductive objects such as jewelry.
2. The high-voltage battery contains hazardous materials. Escaping gases or fluids may cause chemical burns or blindness. Always wear appropriate protective equipment when working near the battery. If contact occurs, rinse with clean water for at least 15 minutes and seek immediate medical attention.
3. The high-voltage battery may ignite under certain conditions. Never expose it to open flames, sparks, or excessive heat. Handle the battery carefully to avoid damage or leakage.
4. Keep children away from the high-voltage battery and related components at all times.
5. Refer to the Volkswagen ID.4 Owner’s Manual and workshop documentation for further safety information.
6. Improper handling of the high-voltage battery can lead to serious injury or death. Never open or disassemble the battery housing.
7. Maintenance must only be performed by qualified professionals. Never allow water or liquids to contact open high-voltage components, as this may cause short circuits, burns, or electric shock.

Introduction

Requirements

✓ The drive system of the Volkswagen ID.4 must be switched off.

✓ The charging cable and charging infrastructure must be in proper working condition and verified → .

Types of charging

• AC (alternating current) charging at a wall box or charging station (→ Charging processes).

  This method provides efficient and consistent charging performance. The actual charging power depends on the station, cable, and onboard charger of the Volkswagen ID.4.

• AC charging via a household socket (→ Charging processes).

  The domestic electrical installation must be checked and certified → . Charging time is significantly longer, so overnight charging is recommended.

• DC (direct current) fast charging at a compatible station (→ Charging processes): This method delivers very high charging power and significantly reduces charging time. Follow all guidelines regarding frequent DC charging → .

NOTICE

Frequent use of high-power DC fast charging may gradually reduce the long-term capacity of the Volkswagen ID.4 high-voltage battery.

• Whenever possible, prioritize AC charging at a wall box or charging station to preserve battery health.

When using AC charging, it is recommended to charge at maximum available power at a charging station or wall box, as this is more efficient than using a standard household socket.

Refer to the technical specifications of your Volkswagen ID.4 for exact charging capabilities. For further details, contact an authorized Volkswagen dealer or service facility.

WARNING

Failure to follow safety instructions when handling the high-voltage system or charging equipment in the Volkswagen ID.4 may lead to electric shock, fire, explosion, or serious injury.

• Always stop the charging process before disconnecting the plug.
• Follow all safety instructions provided with the charging cable.
• Use only certified and professionally installed household connections.
• Do not charge in areas with explosion risks.
• Keep all electrical components dry and protected from moisture.
• Avoid performing maintenance or other work on the vehicle during charging.

WARNING

Driving with a low battery level in the Volkswagen ID.4 may cause the vehicle to stop unexpectedly, increasing the risk of accidents and injuries.

• Always ensure sufficient charge before starting a journey.

The Volkswagen ID.4 high-voltage battery must only be charged using compliant charging infrastructure that meets regional standards such as:

• IEC 61851 and IEC 62196 (Europe).
• GB/T 18487 and GB/T 20234 (China).
• SAE J1772 (Japan, USA, and Canada).

Sticker for the correct charging socket

Fig. 1 Sticker for AC charging and type 2 plugs A on the vehicle and B on the charging station.

Fig. 2 Sticker for DC charging and CCS plugs on the vehicle A with a voltage up to 500 V and B up to 920 V.

The symbols displayed on these stickers help confirm whether the charging system of the Volkswagen ID.4 is compatible with the available charging infrastructure → .

These markings may appear on the vehicle charging port, on charging station components, or directly on the charging cable used with the Volkswagen ID.4.

The Volkswagen ID.4 combines advanced electric mobility with strict safety standards, and understanding these warning signs is essential for safe operation and maintenance.
