Preparing and Performing a Jump-start
Please read the introductory information and heed the Warnings and Notice ⇒
and Introduction.
276
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, otherwise current could already
flow when connecting the positive battery terminals.
Make sure the terminal clamps have sufficient contact with metal.
Jumper cable
So that vehicles can be jump-started, an appropriate jumper cable is required.
The following jumper cable wire diameters must not be fallen short of by the vehicle providing the jump-start.
Vehicles with electric drivetrain: To jump-start the vehicle with a drained 12 V vehicle battery, the wire diameter of the jumper cable must be at least 25 mm2
(0.038 in2).
Vehicle Receiving the 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 and contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Vehicle Providing the Jump-start
1. Pay attention to the operating instructions provided by the vehicle manufacturer.
2. Check that the battery providing the jump-start has the same voltage (12 V) and approximately the same battery capacity as the dead 12 V vehicle battery. Pay
attention to the information printed on the battery of the vehicle providing the jump-start.
