Volkswagen Polo Owners Manual / Starting the engine with jump leads / Introduction

This chapter contains information on the following subjects:

→ Positive and earth jump lead connection points
→ How to start the engine using jump leads

If the engine fails to start because the vehicle battery is flat, the flat battery can be connected to the battery of another vehicle to start the engine. Before using jump leads, check the window on the vehicle battery .

Jump leads must comply with DIN 72553, see manufacturer's documentation. The wire cross section must be at least 25 mm² for petrol engines and at least 35 mm² for diesel engines.

WARNING

Using the jump leads incorrectly or completing the jump start procedure incorrectly can cause the battery to explode, which can lead to severe injuries. Please note the following in order to reduce the risk of the battery exploding:

All work on the vehicle battery and the electrical system can cause serious chemical burns, fire and electric shocks. Always read the warnings and safety information before carrying out any kind of work on the vehicle battery .

The vehicle battery providing assistance must have approximately the same voltage as the flat vehicle battery (12 volts) and approximately the same capacity (see imprint on battery).

Never charge a vehicle battery once it has been frozen. Discharged vehicle batteries can even freeze at temperatures of around 0°C (+32°F).

The battery should be replaced if it is or has ever been frozen.

A highly explosive mixture of gases is given off when the vehicle battery is jump started. Always keep fire, sparks, naked flames and lit cigarettes away from the vehicle battery. Never use a mobile telephone when the jump leads are being connected or disconnected.

Only charge the battery in a well-ventilated space as the battery emits a highly explosive mixture of gases when the vehicle is being jump started.

Position the jump leads so that they never come into contact with any moving parts in the engine compartment.

Never confuse the negative and positive terminals or connect the jump leads incorrectly.

Observe the jump lead manufacturer's instructions.

NOTICE

Please note the following in order to avoid considerable damage to the vehicle electrical system:

A short circuit can be caused if the jump leads are wrongly connected.

The vehicles must not touch each other, as any contact could mean that electricity could flow as soon as the positive terminals are connected.
