  • In addition, please note that the use of replacement parts that are not genuine Porsche parts or approved parts, or the use of accessories not approved by Porsche may also detrimentally affect your vehicle warranty.
  • Check your vehicle regularly for signs of damage. Damaged or missing aerodynamic components, such as spoilers or underbody panels, impair vehicle handling and must therefore be replaced immediately.

Radiator fan
For information on radiator fans:

  • Please see the chapter "RADIATOR FANS" on page 245.

Radiator Fans

The fans can start running depending on the temperature, even with the engine switched off.

  • Exercise extreme care that parts of the body, articles of clothing or jewelry do not get caught in the radiator fan.
  • Exercise extreme caution when working in the area of the radiator fans.

Measurements on test stands
Performance test
Performance tests on roller-type test stands are not approved by Porsche.

Brake tests
Brake tests must be performed only on roller-type test stands.

The following limit values must not be exceeded on roller-type test stands:
– Test speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds

Testing the electric parking brake
Electric parking brake tests on the brake test stand must only be performed with the ignition switched on and with the manual gearshift lever in neutral or the Tiptronic S selector lever in position N.

The vehicle switches automatically to brake test stand mode, in which the electric parking brake can be tested.

The message "Electric parking brake in service mode" appears on the multi-purpose display of the instrument panel.

Balancing wheels on the vehicle
During finish balancing of the wheels, the entire vehicle must be lifted and the wheels must be free to turn.

Engine Oil
It is important to perform oil changes regularly in accordance with the intervals specified in your Maintenance Schedule.

Engine oil consumption
It is normal for your engine to consume oil.

The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant.

If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1000 km) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an expressway, making it then appear that oil is excessively consumed after driving at high speeds.

If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater.

If the vehicle is driven at a high rate of speed, climatic conditions are warm, and the load is high, the oil should be checked more frequently, as driving conditions will determine the rate of oil consumption.
– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts. Therefore, the engine oil should be
checked regularly and kept at the required level.
– Make it a habit to have the engine oil level checked with every refueling.
