WARNING

Checking the acid level

Risk of explosion!

Applies to a 12V battery with an acid level indicator.

Hydrogen is released during charging. An explo-

sion can also be caused by sparks, for example,

when disconnecting or loosening the cable con-

nector.

Never charge a frozen or thawed 12V battery.

·

Do not “quick charge” a 12V battery yourself,

have it done by a specialist garage.

NOTICE

A flat 12V battery can freeze easily!

— Tap on the indicator before testing to clear air

bubbles.

What you should be mindful of

Replacing a fuse

NOTICE

Fire hazard and risk of damage to the electrical sys-

tem.

Do not repair fuses or replace them with higher-

rated fuses.

·

Replace the defective fuse with a new fuse with

the same amperage.

·

We recommend using replacement fuses from the

·

Volkswagen Genuine Accessories range. These

guarantee reliable and safe protection of the ve-

hicle’s electric system.

— Replace the fuse by means of the clamp located

on the inside of the fuse box cover in the engine

compartment.

If a newly inserted fuse blows again, seek assis-

tance from a specialist garage.

·

Use the appropriate end of the clamp based

on the fuse dimensions.

One fuse may serve several consumers. One

consumer may have several fuses.

NOTICE

Dirt and moisture in the fuses can cause damage to

electrical equipment!

Protect the fuses from dirt and moisture.
