Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle an d could cause serious
personal injuries or death.
f Do not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause
severe personal injury.
f Specialized high performance tires on high
performance sports cars exhibit more wear
than those on a family sedan, or even a high
performance sedan.
Therefore, it is important to check your tire
pressure and condition at least every two weeks.
If you notice that tires are wearing unevenly, con-
sult your Porsche dealer.
Uneven wear 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 f Avoid damaging tires and wheel rims.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncture High-pressure cleaning units can damage the
tires.
f Please see the chapter “HIGH-PRESSURE
CLEANING UNITS, STEAM CLEANERS” on
Page 203.
f Check tires for imbedded material, cuts, punc-
tures, cracks and bulges (side wall) before driv-
ing off.
In case of tire damage, where it is uncertain wheth-
er there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that
the difference in tread depth on one axle must not
exceed 30%.
Handling inconsistencies may result.
f Perform a visual inspection if necessary.

Battery The battery is located in the front luggage
compartment under a black plastic cover.
f Please see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 74.
f Please see the chapter “EMERGENCY UNLO-
CKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 238.
Warning!
Risk of short circuit, fire and damage to al-
ternator and electronic control units, result-
ing in serious personal injury or death.
f Observe all warning notes on the battery.
f Disconnect the negative terminal on the bat-
tery during all work on the electrical system.
f Do not lay tools or other metal objects on the
battery as they could cause a short circuit
across the battery terminal.
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
f Do not expose the battery to an open flame,
electrical spark or a lit cigarette.
f Do not wipe battery with a dry cloth.
Risk of serious personal injury or death and
damage to the fabric, metal or paint. f
Wear eye protection.
f Do not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
f If you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-
tor.
f Spilled electrolyte must be rinsed off at once
with a solution of baki ng soda and water to
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
f Always protect your skin by washing thorough-
ly with soap and water.
Risk of explosion as a result of static charge,
resulting in serious personal injury or death.
f Do not wipe the battery with a dry cloth.
f Eliminate potential electrostatic charge by
touching the vehicle before touching the bat-
tery.
Charge state A well-charged battery prevents starting problems
and has a longer service life.
Traffic density, requirements regarding noise, ex-
haust gas and fuel consumption reduce the engine
speed and, hence, the alternator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid discharging the battery
unintentionally:
f Switch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
f Always remove the ignition key from the igni-
tion switch when leaving the car.
f Avoid frequent operation of the Porsche Com-
munication Management system and audio
system when the engine is not running.
f In the cold season in particular or if the vehicle
is used primarily for short journeys, it may be
necessary to recharge the battery from time to
time.

Adjusting HeadlightsfPlease see the chapter “LIGHTS, REPLACING
BULBS” on Page 247.
Adjustment
The adjustment is made wi th the vehicle ready to
drive and the fuel tank completely filled.
The driver’s seat must be loaded by a person or a
165 lbs. (75 kg) weight and the tire pressures
must meet the prescribed values.
After being loaded, the car must be rolled a few
meters so that the suspension can settle.
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.)
has to be projected on a ve rtical screen (wall) in
distance of 24.6 ft. (7.5 m) from the front lens of
the headlamp.
The correct position of the cutoff is 2.0 in. (5 cm)
at 24.6 ft. or 7.5 m (0.4 °) below a horizontal line,
x cm from ground to the center of the headlamp
lens. Lateral adjustment of the
headlights should be
carried out at a specialist workshop with an optical
adjustment unit.
Distance
Visual aim shall be perf ormed at not less than
24.6 ft./7.5 m (this value is a rounded down con-
version from the 25-foot distance typical of field
aim using a screen). The 24.6 ft./7.5 m distance
is measured from the headlamp lens to the view-
ing screen.

Porsche also recognizes that these fuels may not always be available. Be assured tha t your vehicle will operate
properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), since the engine’s
”Electronic Octane™ knock control“ will adapt the ignition timing, if necessary.
