Checking engine oil level

> Check oil level regularly (if possible at every refuelling).

> Oil level must not fall below the minimum mark or rise above the maximum mark.

> Only use engine oils tested and approved by Porsche AG.

Note. The engine oil level can only be checked with the display in the instrument cluster. Any malfunctions in the oil level indicator show up via a warning in the instrument cluster. Use the Info function to display the requirements for oil level measurement.

Note. If the oil level drops below the minimum mark, the segment below starts flashing! The difference between the minimum and maximum marks is approx. 1.2 liters, one segment of the display corresponding to approx. 0.4 liters of oil. Never fill or top up with engine oil above the maximum mark.

Requirements for correct oil level measurement (not during refuelling)

1. Vehicle is parked horizontally.
2. Engine is off.
3. Ignition switched on.

Oil return time: Before measuring the oil level, the engine oil must have returned to the oil pan. The duration depends on the temperature and the time the engine has been stationary.

Starting measurement

Scheme 1

Note. The waiting time for the oil level measurement is indicated by a countdown time display and cycling segments on the oil level indicator. Short waiting times when measuring the engine oil level are obtained after the vehicle has been idle for a long period or if the engine is at operating temperature.

1. Switch on the ignition (do not start the engine). Measurement starts automatically. The display for the oil level measurement appears on the on-board computer.

Scheme 2

Note. The oil level must be between the minimum and maximum marks. Adjust the engine oil level if necessary (pour engine oil in slowly) and check the level again.

2. The oil level can be read off from the segment display after measurement is completed (at end of waiting time). The permitted oil level lies between the minimum and maximum marks.

Scheme 3

3. If the lowest segment of the oil level indicator is filled --> Minimum oil level, the minimum oil level has been reached and the oil must be topped up immediately --> 17 01 55 Engine oil and oil filter change - as of MY 2005 (All Models). (Scheme 3)
