may not always be due to improper wheel
alignment. It can be the result of individual
driving habits such as cornering at high
speeds. If the tire pressure is not checked and adjusted regularly,

may not always be due to improper wheel
alignment. It can be the result of individual
driving habits such as cornering at high
speeds. If the tire pressure is not checked and adjusted regularly, abnormal tire wear can
also occur.
Tire care
WARNING
Avoid damaging tires and wheel rims. If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
Frequently check tires for uneven wear and
damage.
Remove imbedded material. Replace worn or damaged tires immediately. Replace missing valve dust caps. Keep oil, fuel, brake fluid, etc. away from
tires.
Keep tires inflated correctly.

Tire replacement
In the interest of maximum safety and best
all-around car handling, always buy
replacement tires that have the same
specifications with regard to tire size,
design, load carrying capacity, tread
pattern, tread depth etc. This also applies
to Porsche recommended alternate
replacement tires. If you do not use a
Porsche recommended replacement tire,
make sure that you purchase your new
tires from a reputable

tire specially dealer and that the dealer complies with all manufacturers warnings
for those tires.
In case of tire damage where it is uncertain
whether there is a break in the ply with all its consequences or, tire damage caused by
thermal or mechanical overloading due to a
loss of pressure or any other prior damage,
we recommend that the tire be replaced for safety reasons.
If one faulty tire on an axle is replaced it
should be noted that the difference in tread
depth on one axle must not be more than
30%.
Tire specifications are imprinted on the
sidewall of the tires. If in doubt, check with
your Porsche dealer.
When replacing tubeless tires, always install
new valve stems. When replacing tires
requiring an inner tube, always install new
tubes.
New tires do not possess maximum
traction. They tend to be slippery. Break
new tires in by driving at moderate speed
for the first 60-120 miles or 100-200
kilometers.
Wheel balancing
A wheel should always be balanced after a tire repair. Even with regular use a wheel can
get out of balance, and should therefore be
balanced from time to time. Unbalanced
wheels may affect car handling and tire life.
When balancing light alloy wheels, use only
adhesive balancing weights supplied through
the Porsche parts service.

Wheels
If you intend to use other than original
equipment wheels, be sure that they conform
to Porsche specifications for your model.
Check with your Porsche dealer regarding the
correct wheel specifications for type and
model year.
Removing and storing tires
The driving direction should be clearly marked on all tires before removing them for storage,
to make sure they are mounted and run in the
same direction as before. Store tires in a cool
and dry place. Tires without rims upright!
Avoid contact with oil, grease or gasoline. When remounting, put tires with the most
tread depth at the front.
Snow tires
For a better grip on snow and ice use radial M + S tires or snow tires with studs. Check with
your local Motor Vehicle Bureau for possible
restrictions.
Radial ply M+S tires should be inflated with
the same cold tire inflation pressures required
for the regular radial ply tires. However, do not exceed the maximum tire inflation pressure
listed on the tire sidewall.
Snow tires should have the same load
capacity as original equipment tires and
should be mounted on all four wheels. Snow
tires with studs should be run at moderate
speeds when new in order to give the studs
time to settle.

83

WARNING
Tires with badly worn treads and studs are
very dangerous. Make sure they are replaced
immediately.
Do not drive a vehicle equipped with snow
tires at prolonged high speed. Snow tires do
not have the same degree of traction on dry,
wet or snow free roads as a normal tire. Furthermore, snow tires wear rapidly under
these conditions.
Snow tires do not fulfill their purpose if the
tread depth is less than 5/32 in. / 4 mm.
Comply with all state and local laws
governing snow tire and tread depth
requirements.
Snow chains Should snow chains be necessary, they
must be mounted on the drive wheels
only.

Check with local authorities for possible
restrictions.
Use only Porsche-approved snow chains with
fine pitch links, so that enough
space remains between the chains and the inside of the wheel arches.
Drive wheels must rotate freely with chains
mounted to prevent damage to body, axle or
brake components. Follow instructions issued
by the supplier of the chains. Remove chains
as soon as roads are free of ice and snow.
New Tire Identifications
The European tire manufacturers have
changed their tire identification system for SR
and HR-tires pertaining to maximum
permissible speed and maximum load carrying capacity for belted tires. The following is an
example only.
During the transition period some tires might
show both old and new identification codes,
such as: 215/60 SR 15 M+S 80 Q. In this
instance, the new codes apply.
The identification codes for VR tires
remain unchanged; for example: 205/55 VR
16. (V = maximum permissible speed for radial tires, i.e. over 130 mph or 210 km/h).

If it fails to light up, the fuse is defective and
must be replaced. Replace black plastic
cover.
The central electrical system contains plug in
relays for various electrical switching
functions.
Defective relays should be tested and
replaced by an authorized Porsche dealer.
To prevent damage to the electrical system
we recommend having all work - including the
installation of electrical accessories -carried
out by your authorized Porsche dealer. . ,

Fuses and Relays
The individual circuits are protected by fuses
to prevent damage to electrical leads and
components due to short-circuits and
overload.
The fuse box with a black plastic cover is
located on the left side in the engine
compartment directly in front of pivot point for
left windshield washer arm.
The use of the fuses and relays is shown
in a list on the inside of the cover of the
fuses and relays.
Replacing a Fuse
Before replacing a fuse, turn off all
electrical components and the ignition;
remove the key. Replacing a fuse or relay with the
engine running or the ignition on could
cause electrical shock.

A blown fuse indicates an overload in the circuit. When a fuse is blown it is not sufficient
to merely replace it. The cause of the short
circuit or overload must be located. Fuses
should never be patched up with tin foil or
wire as this may cause serious damage
elsewhere in the electrical circuit.
Open snap-on latches and remove plastic
cover.
To find out whether a fuse is serviceable, pull
it out with the plastic pliers specifically
provided for this purpose. Insert the fuse at
the test point on relay (G 3). If the fuse is in
proper condition, the green indicator light will
come on.
Loudspeakers

When installing a radio or booster amplifier,
check that the output is compatible with the
capacity of the loudspeakers supplied with the vehicle.

Battery-12 Volt
The battery is located under the front hood in
the cowl area.
A replacement battery should always have the same rating as the original equipment battery.
Specifications are printed on the battery
housing.
Before work is done on the electrical
system, the battery must be disconnected
to prevent short circuiting. First
disconnect the negative ground wire and
then the positive cable. To reconnect
battery, reverse the procedure.
Disconnecting the battery while the engine is running will damage the alternator. This
also applies to cars equipped with a
battery main switch.
Never drive the car with a disconnected battery as this will damage the alternator. WARNING

Do not lay tools or other metal objects on the battery as they could cause a short
circuit across the battery terminals.
Do not expose the battery to an open flame or electric spark. Hydrogen gas
generated by the battery is explosive.
Do not let battery acid come in contact with skin, eyes, fabric or painted
surfaces.
If you get electrolyte, which is an acid, in your eyes or on skin, immediately rinse
with cold water several minutes and call a doctor. Spilled electrolyte must be rinsed off at once with a solution of water and baking
soda to neutralize the acid and prevent
damage to fabric and metal.
Checking the electrolyte fluid level
The electrolyte fluid level in your battery can
be checked by unscrewing and opening the
filler vent caps of each cell. The fluid level
should meet the indicator mark in each cell. If
necessary, top off with distilled water.
How often water must be added depends on
operating conditions and on the time of year.
Generally, the electrolyte level must be
checked more often in the summer than in the winter, and more often when driving long distances.
Only fill up to mark, otherwise the electrolyte will overflow when the battery is being charged and cause damage.
Battery care
Battery should be securely mounted
Terminals and connections should be kept
clean and properly tightened. Corrosion can
be prevented by coating terminals and
connections with petroleum jelly or silicone
spray
Vent caps must be securely tightened to
prevent spillage
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop.
Additionally, more power is consumed while starting, and the headlights, heater, rear window defogger, etc., are used more
frequently. Curtail unnecessary power
consumption, particularly in city traffic or when travelling short distances only. Let your
Porsche dealer test the battery's capacity
before winter sets in. A well charged battery
will not only prevent starting problems but will
also live longer.
Battery charging
Automotive batteries lose their efficiency when not in use. The charge available in your
battery can be measured with a hydrometer.
We recommend that battery voltage be tested
by your Porsche dealer who has the
appropriate equipment. If the car is not driven
for prolonged periods, the battery
