Preparing to jump-start
If the engine cannot be started because the 12 V vehicle battery is drained, another vehicle can jump-start it.
NOTICE
A drained 12 V vehicle battery can freeze at temperatures around approx. 0 °C(approx. +32 °F), suffer damage and
fail.
● Always replace a frozen or thawed 12 V vehicle battery.
Preparations
Observe the following for jump-starting:
—Wear suitable eye protection and safety gloves→
.
—Pay attention to the operating instructions provided by the manufacturer of the jump-start cables.
—Open the hood.
—Always use a jumper cable with fully insulated terminal clamps and without any insulation defects for jump-
starting →
.
—Ensure that there is sufficient distance between the vehicle providing the jump-start and the vehicle receiving the
jump-start. If metallic parts of the vehicles come into contact with each other, even just connecting the positive
battery terminals is enough to cause current to flow →
.
—Make sure the terminal clamps have sufficient contact with metal.
WARNING
Performing a jump-start incorrectly can cause the 12 V vehicle battery to explode, which can cause serious injuries.
● Always wear suitable eye protection and safety gloves.
● Never lean over the 12 V vehicle battery.
● Always connect the positive cable first and then the negative cable.
● Never connect the negative terminal to parts of the fuel system or to the brake lines.
● Ensure that there is no contact between the non-insulated parts of the terminal clamps.
● Make sure the cable insulation is free from any defects.
● Make sure that the cable that is connected to the positive battery terminal on the 12 V vehicle battery does not
come into contact with any vehicle components that conduct electricity.
Jumper cable
So that vehicles can be jump-started and can jump-start others, an appropriate jumper cable is required.
2
The cable cross-section of the jumper cables must be at least 25 mm (0,038 in2). The cable cross-section of the
jumper cables for vehicles with diesel engines must be at least 35 mm2 (0.054 in2).
Vehicle Receiving Jump-start
1. Check that the discharged 12 V vehicle battery is properly connected to the 12 V vehicle electrical system.
2. If a 12 V vehicle battery with a viewing window has been installed, check the color of the viewing window. If
the viewing window is light yellow or has no color, do not perform a jump-start; instead, contact an authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
