1. Shine a flashlight on the fuses.

A blown fuse can be recognized from above and from the side through the transparent casing, as its metal strip will be burnt through → fig. 1.

• Standard flat connector fuse (ATO).
• Small flat connector fuse (MINI).
• Large flat blade fuse (MAXI or MAXI+).

Replacing fuses

Fig. 2 Plastic pliers for removing or installing a fuse (general example).

1. If necessary, remove the plastic tongs from either the fuse box or the cover of the fuse box→ fig. 2.

2. Depending on the design of the fuse, slide the appropriately sized clamp on the plastic pliers onto the fuse from above or from the side.

3. Remove the fuse.

4. If a fuse is blown, replace with a fuse with the same rating (same color and same label) and the same size → .

5. After inserting the new fuse, place the plastic pliers back in the cover, if necessary.

6. Reinstall the cover or close the fuse box cover.

NOTICE

If a fuse is replaced by a fuse with a higher current rating, this could damage the electrical system in another location.

• Never replace a fuse with a fuse that has a higher current rating.

Introduction

The vehicle must not be tow started for technical reasons. If the vehicle's drive system cannot be engaged because the 12 V vehicle battery is dead, the 12 V vehicle battery on another vehicle can be used to engage your vehicle's drive system.

For technical reasons, the jump-start points in electric vehicles are not designed for use in jump-starting other vehicles → .

WARNING

Using jumper cables incorrectly and performing a jump-start incorrectly could cause the 12 V vehicle battery to explode. Serious injuries may result.

• Always read and heed the warnings and safety precautions before working on the 12 V vehicle battery (→ 12-V vehicle battery).
• Never confuse the positive battery terminal with the negative battery terminal.
• Never jump-start a vehicle with a frozen or thawed 12 V vehicle battery.

WARNING

During a jump-start, a highly explosive gas mixture builds up at the 12 V vehicle battery. Sparks produced during a jump-start could ignite the flammable gas. Serious injuries may result.

• Always keep fires, sparks, open flames far away from the 12 V vehicle battery.
• Avoid discharging static electricity near the 12 V vehicle battery.

NOTICE

The electrical system of an electric vehicle is not designed to give jump-starts to other vehicles. This can cause significant damage to the electrical system of an electric vehicle.

• Never use an electric vehicle to jump-start another vehicle.

NOTICE

A drained 12 V vehicle battery can freeze, be damaged and fail at temperatures around approx. 0 ºC( approx. +32 ºF).

• Always replace a frozen or thawed 12 V vehicle battery.
