2004 PORSCHE CAYENNE tires

4Dear Porsche OwnerA lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections. These
engineering and safety features will be enhanced
by you...the safe driver...– who knows her/his car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages. If in doubt, have these checks performed
by your authorized Porsche dealer.
Before driving off...Check the following items firstfTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary. Make
it a habit to have engine oil checked with every
refueling.
fCheck all fluid levels such as windshield
washer and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unobst-
ructed.
fCheck air intake slots and area between en-
gine compartment lid and windshield. Ensure
that these areas are free of snow and ice, so
the heater and the windshield wipers work
properly.fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipmentIt is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are: window
scraper, snow brush, container or bag of sand or
salt, emergency light, small shovel, first-aid kit,
etc.

In the driver's seat...fCheck operation of the horn.
fPosition seat for easy reach of foot pedals and
controls.To reduce the possibility of injury from
the airbag deployment, you should always sit
back as far from the steering wheel as is
practical, while still maintaining full vehicle
control.
fAdjust the headrest so that the upper edge of
the headrest is brought to eye level or higher.
fAdjust the inside and outside rear view mirrors.
fBuckle your safety belts.
fCheck operation of the foot and parking brake.
fCheck all warning and indicator lights with
ignition on and engine not running.
fStart engine and check all warning displays for
warning symbols.
fNever leave an idling car unattended.
fLock doors from inside, especially with
children in the car to prevent inadvertent
opening of doors from inside or outside. Drive
with doors locked.
On the road...fNever drive after you have consumed alcohol
or drugs.
fAlways have your safety belt fastened.
fAlways drive defensively.
Expect the unexpected.
fUse signals to indicate turns and lane changes.
fTurn on headlights at dusk or when the driving
conditions warrant it.
fAlways keep a safe distance from the vehicle in
front of you, depending on traffic, road and
weather conditions.
fReduce speed at night and during inclement
weather.
Driving in wet weather requires caution and
reduced speeds, particularly on roads with
standing water, as the handling characteristics
of the vehicle may be impaired due to hydropla-
ning of the tires.
fAlways observe speed limits and obey road
signs and traffic laws.
fWhen tired, get well off the road, stop and take
a rest. Turn the engine off. Do not sit in the
vehicle with engine idling.
Please see the chapter “ENGINE EXHAUST” on
Page 2.fWhen parked, always put the parking brake on
and put the gearshift lever in neutral or the
Tiptronic selector lever in position P.
On hills also turn the front wheels toward the
curb.
fWhen emergency repairs become necessary,
move the vehicle well off the road. Turn on the
emergency flasher and use other warning
devices to alert other motorists. Do not park
or operate the vehicle in areas where the hot
exhaust system may come in contact with dry
grass, brush, spilled fuel or other flammable
material.
fMake it a habit to have the engine oil checked
with every refueling.

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.

Displaying/resetting average
speed
Displaying range on remaining fuelThe range on remaining fuel is continuously
recomputed while driving based on fuel level,
current consumption and average consumption.
Displaying tire pressureThis display is available only in conjunction with the
Tire Pressure Monitoring option.
The current tire pressures at the actually present
levels are displayed in the “Tyre pressure” screen
of the on-board computer. These values would be
identical to those of a pressure gage connected to
the four valves. These pressures change while the
vehicle is being driven.
– The tire pressures increase as the temperature
in the tires rises, e.g. during high-speed
motorway driving.
– The tire pressures decrease as the tempera-
tures drop, e.g. during trips in cold regions
(such as mountains).
The values displayed therefore do not allow
conclusions to be drawn about possible pressure
deviations.
fIn order to display pressure deviations from
the prescribed pressure, select the menu item
TYRE PRESS. in the MAIN MENU.

Setting Tire Pressure Monitoring
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire
pressure increases rate of wear of the
affected tires.
Despite the advantages offered by Tire
Pressure Monitoring, it is not a substitute for
proper tire maintenance, and it is still the
driver’s responsibility to update the settings
in the multi-purpose display and maintain the
correct tire pressure, even if under-inflation
has not reached the level to trigger illumina-
tion of Tire Pressure Monitoring low tire
pressure message. Low tire pressure
reduces the road safety of the vehicle and
destroys the tire and wheel.
fWhen a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the damage with tire sealant or fit the spare wheel.
fDo not by any means continue to drive with
leaking tires.
fSealing the tire with the tire sealant is only an
emergency repair so you can drive to the next
authorized Porsche dealer.
The maximum permitted speed is 50 mph
(80 km/h).
fDefective tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.
fDo not drive with tires whose tire pressure
drops again in a short period of time. Have
tires checked by an authorized Porsche dealer.
fIf Tire Pressure Monitoring is defective (e.g.
defective wheel transmitters), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored by
defective Tire Pressure Monitoring.
For information on warning messages on the
multi-purpose display: Please see the chapter
“OVERVIEW OF WARNING MESSAGES” on
Page 149.
fTire Pressure Monitoring gives a warning about
tire damage due to insufficient tire pressure as
well as about a gradual loss of pressure due to
foreign objects. Tire Pressure Monitoring
cannot warn you about tire damage that
occurs suddenly (e.g. flat tire due to acute
external effects).

fIf a tire pressure message is displayed, correct
the tire pressure at the next opportunity.
fIncomplete entries or selection of the wrong
tires on the multi-purpose display affect
correct indication of warnings and messages.
The settings in the TYRE PRESSURE menu
must be updated after wheel changes, use of
a spare wheel or changes in vehicle loading.
fUse only the pressure differences shown in the
TYRE PRESSURE menu or from tire pressure
messages or warnings when correcting the
tire pressure.

Correct tire pressure.
Functional description of Tire Pressure
MonitoringTire Pressure Monitoring continuously monitors
tire pressure and tire temperature on all four
wheels and warns the driver when the tire
pressure is too low.The display as well as the settings for Tire
Pressure Monitoring take place on the multi-
purpose display in the sub-menu
TYRE PRESSURE.
However, the tire pressure must still be set
manually on the wheel.
The deviations in the tire pressures from the
required pressures are shown in the sub-menu
TYRE PRESSURE.
Example:
If the tire pressure display shows “–4 psi
(–0.3 bar)”, you must increase the tire pressure by
4 psi (0.3 bar).
The tire pressures to be monitored are fixed in the
Tire Pressure Monitoring system and cannot be
changed.
The following settings must be made to permit
correct monitoring.
–Tires
Select the type and size of the tires fitted on
the vehicle.
–Load
Select the type of loading.
Note on operation
Settings can be made only when the vehicle is
stationary.
fFor information on tires and wheels:
Please see the chapter “TIRES/WHEELS” on
Page 281.
Warning!
Your vehicle has also been equipped with a TPM
malfunction indicator to indicate when the system
is not operating properly.
The TPM malfunction indicator is combined with
the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate
tires and wheels allow the TPM to continue to
function properly.Warning light
