Ultrasound sensors
Maintenance notes
fThe sensors must always be kept free of dust, ice and snow in order to ensure that they are fully functional.fDo not damage sensors by abrasion or scratching.fMaintain sufficient distance when cleaning with high-pressure cleaning equipment.The sensors will be damaged if the pressure is too high.
Signal tones/function
When reverse gear is selected, ParkAssist confirms that it is switched on by issuing a short signal tone .
If the vehicle has front ParkAssist, no signal tone will be issued when reverse gear is selected.Instead, the ParkAssist visual display will appear on the central screen of the Porsche communication system.
A detected obstacle is signaled by an intermittent tone . The intervals decrease as the obstacle is approached.
If the distance drops to less than approx. 12 in. (30 cm), a continuous tone sounds.fSet the radio volume so that the signal tones are not drowned out.
The volume of the signal tones can be changed individually.
For information on changing the signal tone volume:fPlease see the chapter “ADJUSTING PARKASSIST VOLUME” on page 126.
Even when using ParkAssist, the driver is still responsible for taking due care when parking and when assessing obstacles.A continuous tone sounds when there is a risk of collision.fDo not drive rearward any further once a continuous tone sounds.
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing obstacles (e.g. winter driving, powder snow, clothing made from fabric or fur),– sound-reflecting obstacles (such as glass surfaces and flat painted surfaces),– and very thin obstacles (e.g. thin posts).
Other ultrasound sources (e.g. pneumatic brakes of other vehicles, sweeping machines and jack hammers) can interfere with the detection of obstacles.

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 Porsche Doppelkupplung 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-function display in 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.– The oil pressure warning light is not an oil level indicator. The oil pressure warning light indicates serious engine damage may be occurring when lit, if engine rpm is above idle speed.
