Fig. 197 Engine compartment: pushing up the vehicle battery sleeve

The electrolyte level of the vehicle battery should be checked regularly in high-mileage vehicles, in hot countries and in older vehicle batteries. The vehicle battery is otherwise maintenance-free.

Vehicles with a start/stop system (  ) are fitted with special vehicle batteries. For technical reasons, it might not be possible to check the electrolyte level in these vehicle batteries.

Preparation

• Preparing the vehicle for working in the engine compartment   .

• Open the bonnet   .

Battery cover

To open, fold the sleeve away in the direction of the arrow  .

To close, fold the cover against the direction of the arrow  .

Checking the electrolyte level

• Ensure that enough light is available for you to see the colours clearly. Never use naked flames or glowing matter (e.g. cigarettes) as a light source.

• The colour display in the round window on the top side of the vehicle battery will change according to the electrolyte level.

WARNING

• Always wear eye protection and protective gloves.

• Electrolyte is very aggressive. It can burn the skin and can cause blindness. When working with the battery, protect your hands, arms and particularly your face from acid spillages.

• Never tilt the vehicle battery. Electrolyte may spill out of the battery vents and cause chemical burns.

• Never open a vehicle battery.

• If acid is spilt in your eye or on your skin, rinse immediately for several minutes with cold water. Then consult a doctor immediately.

• If acid is swallowed, consult a doctor immediately.
