Volkswagen Golf Owners Manual: Introduction
This chapter contains information on the following subjects:
→ Jump lead connection point (earth connection)
→ 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.
Additional information and warnings:
- Preparation for working in the engine compartment

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 the same voltage as the
discharged vehicle battery (12 volts) and approximately the same capacity (see
markings 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.
