2005 PORSCHE CAYENNE S warning lights

8Fuel QualityYour engine is designed to provide optimum performance and fuel economy using
unleaded premium fuel with an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that 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 Oktane™ knock control“ will adapt the ignition timing, if necessary.Fuels containing alcohol and etherSome areas of the U.S. require oxygenated fuels during certain portions of the year.
Oxygenated fuels are fuels which contain alcohols (such as methanol or ethanol) or ether (such as MTBE).
Under normal conditions, the amount of these compounds in the fuel will not affect driveability.
You may use oxygenated fuels in your Porsche, provided the octane requirements for your vehicle are met.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.Fuels containing MMTSome North American fuels contain an octane enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT).
If such fuels are used, your emission control system performance may be negatively affected.
The check engine warning lights on your instrument panel may turn on.
If this occurs, Porsche recommends you stop using fuels containing MMT.

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 prac-
tical, while still maintaining full vehicle control.
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 igni-
tion 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 chil-
dren 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 re-
duced speeds, particularly on roads with
standing water, as the handling characteristics
of the vehicle may be impaired due to hydro-
planing 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 ve-
hicle with engine idling.
Please observe the chapter “ENGINE EX-
HAUST” on Page 6.fWhen parked, always put the handbrake on
and put the gearshift lever in neutral or the se-
lector 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 de-
vices to alert other motorists. Do not park or
operate the vehicle in areas where the hot ex-
haust system may come in contact with dry
grass, brush, fuel spill or other flammable ma-
terial.
fMake it a habit to have the engine oil checked
with every fuel filling.

stop and open again by several inches.
However, this is not the case if:
– The rocker switch is pressed again within
10 seconds of the window being blocked and
– The windows are closed using the car key in
the door lock (comfort function).
The windows close with their full closing force.
Warning!
Danger of injury. If the rocker switch is
pressed again within 10 seconds of the
window being blocked, the window will close
with its full closing force.
fTake care to ensure that nobody can be injured when the windows close.
One-touch operation is disabled for 10 seconds
after blockage of the door window.
Storing final position of the door windowsThe end positions of the door windows are lost
when the battery is disconnected and reconnect-
ed. The one-touch operation of the windows is dis-
abled.

Belt tensionerDepending on the force of a collision, fastened
seat belts are automatically tightened in an acci-
dent.
The belt tensioners are triggered in:
– Front and rear impacts
The belt tensioners are not triggered in:
–Side impacts
– Vehicle overturning
Maintenance note
The belt tensioner system can be triggered only
once; the system must be replaced afterwards.
Work may be performed on the belt tensioner
system only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered.
This does not indicate a fire in the vehicle.An audio-visual warning system is interconnect-
ed with the driver’s safety belt.
Every time the ignition is turned on, the gong will
sound for about 6 seconds to remind driver and
passenger to buckle up.
In addition, the gong will sound if vehicle speed
exceeds 6 mph (10 km/h.)
The safety belt warning lights in the instrument
panel and on-board computer will go off as soon
as the driver has buckled up.

Controls, Safety, Instruments Danger!
To provide optimal occupant protection, air-
bags must inflate at very high speed. If you
are not wearing your safety belt or are too
close to the airbag when its deployed, inflat-
ing airbags can result in serious personal in-
jury or death.
fMake sure there are no people, animals or ob-
jects between the driver or passenger and the
area into which the airbag inflates.
fSit back as far from the dashboard or steering
wheel as is practical, while still maintaining full
vehicle control.
fDo not lean against the inside of the doors.
fAlways hold the steering wheel by the outer
rim. Never rest your hands on the airbag panel.
fNever transport heavy or sharp objects on or
in front of the passenger seat.
fAlways keep the lid of the door storage com-
partment closed. Objects must not protrude
out of the door storage compartment.
fGive your passenger all of the information in
this chapter.
fNo changes must be made to the wiring or
components of the airbag system.fDo not add any additional coverings or stickers
to the steering wheel or in the area of the pas-
senger airbag and side airbags. Doing so may
adversely affect the functioning of the airbag
system or cause harm to the occupants if the
airbag system should deploy.
fDo not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the airbag
wiring harnesses. Doing so may disable the air-
bag system or inadvertant inflation.
fIf the warning light comes on, the airbag sys-
tem should be repaired immediately by your
authorized Porsche dealer.
fAlways keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area.
Note
Airbag components (e.g. steering wheel, door
trim) may be disassembled only by an authorized
Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer.Faults are indicated by a warning light on the ta-
chometer and a message on the instrument
panel’s multi-purpose display.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 108.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag sys-
tem is functioning properly:
– If the warning light does not light up when the
ignition is switched on or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
