  • If the warning message does not disappear, have the fault remedied at an authorized Porsche dealer.

Until the warning message disappears, you can expect a higher fuel consumption and, under certain circumstances, a decrease in engine power.

Combustible materials close to the exhaust system
The exhaust system becomes extremely hot when the engine is running. Combustible materials in the vicinity of the exhaust system may ignite.

Additional rust or undersealing protection in the area around the exhaust system may become too hot and ignite when driving.

  • Do not apply additional underbody protection or rust protection agent on or near the exhaust manifolds, exhaust pipes, diesel particulate filter or heat shields.
    The protective material could overheat and ignite while you are driving.
  • Do not drive or park your vehicle where combustible materials, such as dry grass or leaves, can come into contact with the hot exhaust system.

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 to the 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.

The EPA estimated miles per gallon (mpg) is to be used for comparison purposes, actual mileage may be different from the estimated mpg, depending on your driving speed, weather conditions and trip length. Your actual highway mileage may be less than the estimated mpg.

  • Please observe all local and national speed limits.
