WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
Information
- This is the battery that is installed as standard.
- The maintenance-free battery has an inspection glass.
- The charge state and acid level of the battery can be checked via the inspection glass -B- .
- If a battery is more than 5 years old and the indicator of the inspection glass is colourless, replace the battery.
- If the battery has been charged, air bubbles can form under the inspection glass. Before carrying out a visual inspection, tap carefully on the inspection glass with something like the handle of a screwdriver.
Three different colour indications are possible:
| Colour indication | Charge state |
|---|---|
| Green | The battery is charged sufficiently. |
| Black | The battery is not charged or the charge is too low. |
| Colourless or yellow | Critical acid level is reached. => Replace the battery. |
Information
- Make sure that vent hose -A- is not kinked or damaged. If in doubt, replace it.
- Vent hose -A- must be inserted in the battery and in the battery box.
