A slight decrease in the fluid level due to wear and automatic readjustment of the disk brakes is normal.

If, however, the fluid level falls markedly or below the minimum mark, the braking system may have developed a leak.

  • Have the brake system checked without delay at an authorized Porsche dealer.

Changing the brake fluid
Brake fluid absorbs moisture from the air over time. This accumulation of water lowers the boiling point and, under certain operating conditions, can affect the braking performance.

Therefore have the brake fluid changed in accordance with the change intervals stated in the brochure "Maintenance".

Warning light USA
Warning light Canada

– The warning lights on the instrument panel and on the on-board computer indicate an insufficient brake fluid level.
– If the warning light lights up on the instrument panel and the warning message appears on the on-board computer
in combination with a larger pedal travel, a brake circuit may have failed.

If the warning lights should light up when driving:

  • Stop immediately in a suitable place.
  • Do not continue driving.
    Consult an authorized Porsche dealer.

Fuel Economy
Fuel economy will vary depending on where, when and how you drive, optional equipment installed, and the general condition of your car.

A car tuned to specifications and correctly maintained, will help you to achieve optimal fuel economy.

  • Have your vehicle tuned to specifications. Air cleaner should be dirt free to allow proper engine "breathing".
    Battery should be fully charged.
    Wheels should be properly aligned.
    Tires should be inflated at correct pressure.
  • Always monitor your fuel consumption.
  • Drive smoothly, avoid abrupt changes in speed as much as possible.
  • Avoid jack rabbit starts and sudden stops.
  • Do not drive longer than necessary in the lower gears. Shifting into a higher gear early without lugging the engine will help save fuel.
  • Prolonged "warm up" idling wastes gas. Start the vehicle just before you are ready to drive. Accelerate slowly and smoothly.
  • Switch off the engine if stationary for longer periods.
  • Any additional weight carried in the vehicle reduces fuel economy. Always keep cargo to a minimum and remove all unnecessary items.
  • Organize your trips to take in several errands in one trip.
  • All electrical accessories contribute to increased fuel consumption.
  • Only switch on the air conditioning when necessary.
  • Do not drive with the Roof Transport System mounted unless you need it.
