Vehicle Damage Warnings






Points to bear in mind when handling the battery
1 Take care to connect the battery cables correctly.

If the cables are connected wrongly for only an instant, the rectifier in the alternator will be rendered unserviceable.

Therefore, always connect:
- the positive battery cable to the positive battery terminal.
- the negative battery cable to the negative battery terminal.

When temporarily connecting an external current source, such as another battery, to the car battery:
- always connect positive terminal to positive terminal
- always connect negative terminal to ground.

2 Do not connect or disconnect the battery while the engine is running.
3 When boost-charging the battery, disconnect both battery cables.


WARNING: The battery contains acid.


4 Always wear rubber gloves and goggles when doing any work where there is a danger that battery acid might be splashed.


WARNING: If battery acid splashes into your eyes, rinse them immediately in running cold water for at least 10 minutes.


5 Make sure that the battery is always kept upright and horizontal. Otherwise the acid might run out and cause damage through corrosion.
6 Never place tools or other objects on top of the battery.
