Check the electrolyte level at every regular service. More regular checks may be required for cars with heavy usage or used in hot climates. Always check the electrolyte level both before and after charging the battery.

Remove the battery plugs
Check the level in all the battery cells. Each cell has its own maximum mark (A). It is recommended that a flashlight is used.
Top up to the maximum mark (A) using distilled or deionized water. Never use tap water . Tap water may damage the battery.

CAUTION: Never fill above the maximum mark (A) This may cause the electrolyte to leak.

Install plugs.
Never switch gray plugs (with a gas release filter) with black sealed plugs
Tighten the plugs fully.

WARNING: Remember that the battery contains oxyhydrogen . Oxyhydrogen is highly explosive . A naked flame or smoking near the battery can cause it to explode resulting in personal injury and/or damage to the car.

WARNING: The battery contains sulphuric acid . This can cause serious corrosive damage . If the electrolyte comes into contact with your eyes, skin or clothes - flush using large quantities of water. Contact a doctor immediately if acid splashes into eyes.
