Volkswagen Golf Variant / Jetta. Manual - part 461

 

 

♦ Personnel instructed in protection, such as a trainee or an

apprentice, may only perform work on vehicle Batteries -

A- under supervision of technical personnel, for example,

a master automotive technician or a master automotive

electrician.

♦ Acid has strong corrosive properties. If Batteries - A- are

handled inappropriately, there is a risk that personal injury

may result from exposure to harmful electrolyte influen‐

ces. Therefore, suitable remedies for acid damage must

be kept readily available. Soapy water would be a suitable

remedy.

♦ If electrolyte drips out from the Battery - A- , skin can be

burned by acid and the vehicle may be affected by acid

erosion and corrosion. It is a possibility that safety-related

vehicle components can be damaged.

♦ When charging and when resting after charging, explosive

gas is present. In extreme cases, if the Battery - A- is han‐

dled inappropriately, the emitted gases may cause the

battery to explode.

♦ Replace a Battery - A- if the visual indicator has »no color

or is bright yellow«. They may not be tested or charged

and jump starting may not be used. There is a risk of ex‐

plosion during testing, charging or jump starting.

♦ Producing sparks by sanding, welding, cutting and open

flames, (also from smoking near the battery) is forbidden.

Producing sparks through electrostatic discharge must al‐

so be avoided. Always touch the vehicle body before

touching the Battery - A- .

♦ Only perform Battery - A- procedures in suitable and well-

ventilated locations.

Battery Safety Label

Safety Label on the Battery - A-
1 - When working in the area of the Battery - A- , fire, sparks,

open flame and smoking are prohibited. Avoid sparks when

working with cables and electrical devices, and from elec‐

trostatic discharge. Avoid short circuits. For this reason,

tools should not be rested on the Battery - A- .

2 - Wear protective eyewear when working on the Battery - A- .
3 - Always keep acid and Batteries - A- out of the reach of chil‐

dren.

4 - Disposal: old batteries require special disposal. They may

only be disposed of at a suitable collection facility and only

in consideration of legal regulations.

5 - Do not dispose of old batteries in household waste.
6 - When handling Batteries - A- , there is a risk of explosion.

Battery - A- charging produces a highly explosive gas mix‐

ture.

7 - Always follow instructions on the Battery - A- , in the Parts

Catalog and in the Owner's Manual.

8 - Danger of burns: battery acid is severely corrosive, there‐

fore protective gloves and eyewear must be worn when

working on the Battery - A- . The Battery - A- must not be

tipped because acid may spill from the ventilation openings.

1.3.3

Working on Airbag System

WARNING

When working on the airbag system (pyrotechnic components,

Airbag Control Module - J234- , wiring), the ground cable must

be disconnected with the ignition switched on.
Exceptions: On vehicles with a battery in the vehicle interior,

the ignition must be switched off.

♦ Then cover the negative terminal.
♦ After disconnecting the battery, a wait time of 10 seconds

is required.

♦ The battery must be connected with the ignition switched

on.

♦ There must be no one inside the vehicle when connecting

the battery.

Make sure in this case to keep oneself away from the airbag

deployment and belt tensioner zones.
If the ignition is not switched on after reconnecting the battery

(the indicator lamps in the instrument cluster do not illuminate),

the ignition (key/button) may only be switched on while sitting

in the driver's seat in the rearmost position.
