5. Press together the housing cover with the air intake funnel (944 Turbo) and carefully
place in position. Tighten fastening screws,
connect hose and screw down hose clamp.

1. Unscrew the retaining screws and remove
the filter cover.
2.
Remove the filter element.
3. Clean the inside of the filter housing with a
lightly oiled lint-free cloth.
4.
Fit a replacement filter element. Carefully
place the housing cover in position and
tighten the retaining screws.

Reservoir for Windshield and Headlight
Washer System
The transparent reservoir is in the engine
compartment. As clear water is usually
inadequate for cleaning windshield or
headlights, add a cleaning solution, such as
windshield washer solvent and antifreeze offered by your dealer. To assure that the
system also functions at freezing
temperatures, antifreeze must be added to the water beforehand. Follow the instructions on the can for the right amount to be used (also
see "Filling Capacities"). Do not use engine
coolant anti-freeze or any other solution
that can damage the car paint.

Tires/Wheels
The original equipment tires and wheel rims
on your Porsche comply with all applicable
Federal Motor Vehicle Safety Standards.
For your driving safety remember the
following:
Wheel rims and wheel bolts are matched to
fit your Porsche.
If you intend to use other than original equipment wheels, be sure that they conform to Porsche specifications for your model. The use of wheel rims and wheel bolts that
do not meet specifications of the original
factory installed equipment will affect the safe operation of your vehicle. Before you plan on exchanging wheels, or winter tires already mounted on wheel rims, consult your Porsche dealer. He has the
technical information necessary to advise
you which wheel rims and wheel bolts are
compatible with the original factory
installations.
Tire pressures
WARNING
Incorrect tire pressures cause increased
tire wear and adversely affect road holding of the vehicle, leading to loss of control.
Always use an accurate tire pressure
gauge when checking inflation pressures.
Do not exceed the maximum tire inflation
pressure listed on the tire sidewall. (Also
refer to "Technical data"). Cold tire infla-

tion pressure means: when a car has not been driven for at least 3 hours or less
than 1 mile. Never let any air out of warm
tires to meet cold tire pressure
specifications.
Tire traction
WARNING
When driving on wet or slushy roads, a
wedge of water may build up between the
tires and the road. This phenomenon is
known as aquaplaning and may cause
partial or com
plete loss of traction, vehicle control or stopping ability. Reduce speed
on wet surface.
Tire Life
Tire life depends on various factors, i.e.,
roads, traffic and weather conditions, driving
habits, type of tires and tire care.
Inspect your tires at least
every 2.000 miles or 3.000 km for wear and damage. If you notice
uneven or substantial wear, wheels might
need alignment or tires should be balanced or
replaced.
Tires must always remain on same side of
vehicle.
After changing, adjust tire pressure and torque wheel nuts diagonally to 94 ft Ibs (130 Nm) (see "Changing wheels").
The supposition that tire durability and
performance are immune to the effects of
storage and age is unfounded. Chemical
additives, which make the rubber elastic, lose
their effectiveness in the course of time and
the rubber becomes brittle and cracks.

Therefore, the tires, especially the collapsible
spare tire, should from time to time undergo a
visual check. To accomplish this,
pump up the collapsible spare tire.
Under no circumstances should tires older
than 6 years be used on your Porsche. The
age of the tire can be obtained from the "DOT" code number. If, for example, the last three
numbers read 125, then the tire was produced in the 12th week of 1985.
Tire wear
The original equipment tires on your Porsche
have built-
in wear indicators. They are molded into the bottom of the tread grooves and will
appear as approximately 1/2 in (12 mm)
bands when the tire tread depth is down to
1/2 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the
tires. We recommend, however, that you do
not let the tires wear down to this extent. Worn tires cannot grip the road surface properly,
and are even less effective on wet roads.
In the United States, state laws may govern
the minimum tread depth permissible. Follow
all such laws.
WARNING
Do not drive with worn tires or tires
showing cuts or bruises as they may lead
to sudden deflation.
If you notice that tires are wearing unevenly,
consult your Porsche dealer. Uneven wear
