2004 PORSCHE CAYENNE climate control

6Break in hints for the first
2,000 miles (3,000 kilometers)The following tips will be helpful in obtaining
optimum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, the moving parts must still wear
in with each other. This wearing-in occurs mainly in
the first 2,000 miles (3,000 km).Therefore:fPreferably take longer trips.
fAvoid frequent cold starts with short-distance
driving whenever possible.
fAvoid full throttle starts and abrupt stops.
fDo not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
fDo not run a cold engine at high rpm either in
Neutral or in gear.
fDo not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
fNever lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period.fDo not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles (3,000 kilometers).
There may be a slight stiffness in the steering,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and brake discsNew brake pads and discs have to be “broken in”,
and therefore only attain optimal friction when the
car has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This also applies whenever the brake pads
and brake discs are replaced.New tiresNew tires do not have maximum traction. They
tend to be slippery.
fBreak in new tires by driving at moderate
speeds during the first 60 to 120 miles (100
to 200 km). Longer braking distances must be
anticipated.
Engine oil and fuel consumptionDuring the break-in period oil and fuel consump-
tion may be higher than normal.
fPlease see the chapter “ENGINE DATA” on
Page 349.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road
conditions, as well as the amount of dilution and
oxidation of the lubricant.
fMake a habit of checking engine oil with every
refueling, add if necessary.

Maintenance and Car Care
Cleaning AlcantarafDo not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush. Heavy abrasion or rubbing when
cleaning causes a permanent change in the
surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in.Cleaning safety beltsfUse mild detergent to clean soiled belts.
fWhen drying, avoid direct sunlight.
fOnly use suitable cleaning agents.
fDo not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.
Storing your PorscheIf you intend to store your Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
fClean your vehicle thoroughly inside and out-
side. Clean the engine compartment. The
under carriage and chassis components
should be free of dirt and salt deposits.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 58 psi (4 bar). It
is not recommended to lift the vehicle, due to
the possibility of corrosion on shock absorber
piston shafts.The vehicle should be moved
slightly, approximately every four weeks, to
prevent flat spot on the tires.
Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
fCheck and correct antifreeze/cleaning solution
level as necessary.Electrical system
fRemove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the alarm
system is deactivated.
fRecharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
fPlease see the chapter “CHARGE STATE” on
Page 320.
Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
fWindows, doors, lids and roof must be closed.
The air vents should be opened.

Minor Repairs
ExampleUniform Tire Quality GradingQuality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific govern-
ment test course. For example, a tire graded 150
would wear one and a half (1-1/2) times as well on
the government course as a tire graded 100. The
relative performance of tires depends upon the ac-
tual conditions of their use, however, and may de-
part significantly from the norm due to variations
in driving habits, service practices and differences
in road characteristics and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire's ability
to stop on wet pavement as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning!
The traction grade assigned to this is based
on braking (straight-ahead) traction tests
and does not include cornering (turned)
traction, acceleration, hydroplaning or peak
traction characteristics.Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire's resistance to the genera-
tion of heat and its ability to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperatures can cause the
material of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately
or in combination, can cause heat buildup
and possible tire failure, resulting loss of
control, leading to serious personal injury or
death.
