Power Steering; Air Filter; Combination Filter; Fluids/Oils For Manual Transmission And Porsche Doppelkupplung (Pdk) - Porsche Boxster Owner's Manual

Power Steering

Warning!
Risk of accident resulting in serious personal
injury or death.
When the engine is stopped (e.g. when being
towed) or the hydraulic system fails, there is
no assistance for steering.
Therefore, substantially more force will have
to be exerted in order to steer.
f Exercise great care when being towed.
f Have the fault remedied at your nearest autho-
rized Porsche dealer.
Note
The flow noise heard at full steering lock is system
related and does not indicate a defect in the
steering system.
Checking hydraulic fluid
f Please see the chapter "EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE"
on Page 196.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
Regular checking of hydraulic fluid is part of
servicing.

Air Filter

A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
f In dusty conditions, check the filter element
more frequently and replace if necessary.

Combination Filter

The fresh air passing through the combination fil-
ter into the passenger compartment is virtually
free of dust, pollen, and unpleasant odors.
f If the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air flow:
f Have filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
maintenance service.
Fluids/Oils for Manual
Transmission and Porsche
Doppelkupplung (PDK)
The transmission fluids/oils have to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
f Please see the chapter "CAPACITIES" on
Page 281.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be
damaged by even a tiny speck of dirt, only a clean
funnel or spout must be used when adding fluid/
oil.
We recommend that you have the fluids/oils
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
f If you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.
