2022 Volkswagen Tiguan Owners Manual - Jump-starting

Jump-starting

 Introduction

For technical reasons the vehicle must not be tow-started ⇒ .

If the engine cannot start because the 12-volt vehicle battery has drained, the 12-volt vehicle battery on another vehicle can be used to start your vehicle.

A suitable jumper cable is required for jump-starting.

The wire diameter for the jumper cable.

• For vehicles with a gasoline engine, at least 25 mm² (0.038 in²).

For a vehicle with a 12 V vehicle battery in the luggage compartment, the jumper cable may only be connected to the jump-start points in the engine compartment.

WARNING

Using jumper cables and performing a jump-start incorrectly can cause the 12 V vehicle battery to explode, which can cause serious injuries. To reduce the risk of the 12 V vehicle battery exploding, heed the following:

• Always read and heed the warnings and safety precautions before working on the 12 V vehicle battery ⇒  Introduction.

• Please note that the vehicle battery supplying the power must have the same voltage (12 V) and approximately the same battery capacity (see the label on the vehicle battery) as the drained 12 V vehicle battery.

• Never switch the positive battery terminal with the negative terminal or connect the jumper cable incorrectly.

• Position the jumper cable so that it will never contact rotating components in the engine compartment.

• Follow the operating instructions provided by the manufacturer of the jumper cable.

• Follow the operating instructions for the vehicle providing the jump-start.

WARNING

During a jump-start, a highly explosive gas mixture builds up at the 12 V vehicle battery.

• Always keep fires, sparks, open flames, and lit cigarettes far away from the 12 V vehicle battery.

• Never use a cell phone while connecting and disconnecting the jumper cable.

NOTICE

A drained 12 V vehicle battery can freeze at temperatures around 32 °F (0 °C).

• Never charge a frozen or thawed 12 V vehicle battery.

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

NOTICE

To avoid the risk of considerable damage to the vehicle electrical system, heed the following:

• Jumper cables that are connected incorrectly can cause a short circuit.

• There must be no contact between the vehicles. Otherwise, current could already be flowing when the positive battery terminals are connected.

• Only use a jumper cable with fully insulated terminal clamps.

NOTICE

Tow-starting can cause damages.
