Battery

Electric shock, short circuit or fire
Touching conductive parts of the vehicle can lead to an electric shock. Short circuits may be caused when working on the vehicle’s electrical system.

The short circuit can cause a fire.

  • Always detach the negative terminal on the battery when working on the electrical system.
  • Tools or conductive items of jewelry (rings, necklaces, watchstraps) must not be allowed to come in contact with conductive parts of the vehicle.

Fire or explosion
Many vehicle fluids are highly flammable, e.g. fuel, engine oil and transmission oil. Fuel vapors can combust. A highly explosive electrolytic gas mixture can form when charging lead batteries.

  • Always detach the negative terminal on the battery when working on the electrical system.
  • To avoid static charges building, do not wipe down the battery with a dry cloth.
  • Before touching the battery, first touch the vehicle itself to allow any static charge to dissipate.
  • Never smoke or use naked flames near the battery. Also beware of sparks, e.g. as a result of cable contact.
  • Only work on the vehicle in the open or in wellventilated spaces.

Corrosive electrolyte
Lead-acid batteries contain corrosive battery acid that can be harmful to skin and damage clothing upon contact.

  • Protective gloves and goggles must be worn.
  • To prevent acid from leaking out, do not tilt the battery.


Risk of short circuit, fire and damage to the generator and electronic control units.

  • The battery should only be removed and installed at an authorized Porsche dealer.
    Porsche recommends an authorized Porsche dealer, as they have trained technicians and the necessary parts and tools.
  • Always detach the negative terminal on the battery when working on the electrical system.

The battery is located under the left front seat.

  • Never connect the black negative jumper cable directly to the battery. Always connect the black negative cable to the ground point B (Fig. 31 on page 69).

For information on jump starting:

  1. Please see chapter “Emergency Starting” on page 113.


Responding to warning symbols

If the battery charge is low, the symbol or appears on the multifunction display. The symbol indicates a fault in the generator.

  1. Please see chapter “Warning and Information Messages” on page 352.

Observe the safety symbols on the battery

Consult the Owner's Manual

Wear protective goggles

Keep batteries away from children

Risk of explosion
A highly explosive electrolytic gas mixture can form when charging the battery, therefore:

Fire, sparks, naked flames and smoking are prohibited
Avoid sparking and short circuits when handling cables and electrical devices. In the case of batteries with central degassing, there is a higher concentration of explosive electrolytic gas at the hose opening. The degassing hose must not be twisted or clogged with dirt.

Risk of chemical burns
Battery acid is highly corrosive, therefore: protective gloves and goggles must be worn.
Do not tilt the battery, as acid can escape from the degassing outlet.
