Inflating Tires
The compressor's filler hose can become hot during the inflation process.

  • Wear gloves.

  1. Switch on compressor.
    The required inflation pressure will be reached after a few minutes.
  2. Switch off compressor.
  3. Check inflation pressure with the pressure gauge. Then reduce tire pressure or add more air if necessary.
    Check the inflation pressure again.
  4. Unscrew the compressor's filling hose.

Reducing inflation pressure

  1. Switch off compressor.
  2. Open air bleed screw on the filling hose until the correct inflation pressure is achieved.

Electrical System
In order to avoid damage and faults in electrical or electronic systems, electrical accessories should be installed at your authorized Porsche dealer.

  • Use only accessories approved by Porsche.

Changing Fuses
Replacing fuses or relays with the engine running or the ignition on could cause electrical shock.

  • Disconnect the negative terminal on the battery during all work on the electrical system.
  • Please see the chapter "BATTERY(12 V)" on page 317.

Relays should be checked or changed only at an authorized workshop.

Electrical accessories can be connected to the 12 V sockets.

Sockets are located in the following positions, depending on vehicle equipment:

  1. under the glove box
  2. in the front cupholder
  3. in the storage tray in the center console (right)
  4. in the loadspace (left)
  5. in the rear center console


  1. The maximum electrical load of a socket is 20 A, but only if no other loads are switched on. Do not exceed 10 A per socket if several loads are operating simultaneously.
  2. The sockets and thus the connected electrical accessories function even if the ignition is switched off or the ignition key is removed.
    If the engine is not running and the accessories are switched on, the vehicle battery will be discharged. The power supply is interrupted after 30 minutes to protect the vehicle battery.
  3. If the load is to be switched on again, the ignition must be switched on once.

Changing fuses
In order to prevent damage to the electrical system due to short circuits and overloads, the individual circuits are protected by fuses.

One fuse box is in the engine compartment. Two additional fuse boxes are located in the outer ends of the dashboard.

  1. Switch off the load with the defective fuse.
    Before replacing a fuse, switch off all electrical consumers and remove the ignition key.
  2. Open the fuse box cover.
  3. Remove the corresponding fuse from its slot in order to check it using the plastic gripper.
    A blown fuse can be identified by the melted metal strip.
  4. Replace only with fuses of the same rating.
    We recommend that you use genuine Porsche fuses for replacement.


  • If a fuse blows repeatedly, please consult an authorized Porsche dealer immediately, so that the short circuit can be located and corrected.
  • Never try to "repair" fuses: you may cause serious damage to other parts of the electrical system.
  • Use the plastic gripper when replacing the fuses. This can be found in the fuse box cover on the dashboard.
  • Spare fuses can be found in both fuse box covers on the dashboard (left: 7.5 and 10 A; right: 20 and 25 A).
