Windshield
washer fluid reservoir The
transparent fluid reservoir is located in the right rear in the engine
compartment, in front of the expansion tank. As clear water is normally not adequate to keep your
windshield and headlights clean, add a cleaning solution to the water. To
assure that the windshield washer and the headlight washer (where applicable)
systems also function at freezing temperatures, anti-freeze/cleaning solution
must be added to the water beforehand.
Follow the instructions on the can for the right amount to be used. Do not use engine coolant antifreeze or any other solution that can damage the car paint. Intensive
windshield cleaning system reservoir The
reservoir is located in the engine compartment beneath the windshield. To
prevent damage and discoloration to paintwork, you should use only
“Porsche Special Silicon Remover”.
Other cleaning agents are not suitable for intensive cleaning, but
can, if this special cleaning agent is not obtainable, be added to the water
of the washer system in the mix ratio stated by the manufacturer. “Porsche Special Silicone Remover” is
safe against frost down to -25°C. The
brake fluid reservoir is located in the engine compartment. The
brake fluid reservoir has three chambers: one for each of the dual brake
circuits, and one for the clutch. Check
the brake fluid level regularly.
Since the reservoir is transparent, the fluid level can be checked
without removing the filler cap.
The fluid level should always be between the MIN and MAX marks. To
add brake fluid, unscrew the cap. The
vent bore in the cap should be kept clean. If
the brake fluid level should drop below the MIN mark, the central warning
light and the brake fluid warning light will flash (see “Central warning light system”). Pull off the road, stop the engine and add brake fluid immediately or contact the nearest Porsche dealer to have the cause located and corrected. WARNING
Power
steering fluid reservoir The
reservoir is located in the engine compartment on the left side. To check fluid level . . .
If the engine
is not running, power assisted steering is no longer effective. You can continue to steer the car but
more effort will be required to turn the steering wheel. Changing
air cleaner filter element A
dirty air cleaner not only reduces engine performance, but can lead to
premature engine wear. The
filter element must be replaced at the intervals listed in your Maintenance
Schedule. If driving is
mostly done in areas where the air is very dusty, the air cleaner should be
checked and cleaned frequently – perhaps daily.
WARNING The
paper filter element must never be cleaned or soaked with gasoline, cleaning
solvents or oil. Doing so may
cause a fire or explosion and result in serious personal injury. |
