2006 PORSCHE CAYMAN warning light

4Fuel Quality Your 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 Octane™ knock control” will adapt the ignition timing, if necessary. Fuels containing alcohol and ether Some 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, that you 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 MMT Some 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.

Environmentally friendly vehicles Modern environmental technology ensures compli-
ance with all emission laws applicable worldwide.
It has the following advantages:
– Rapid operational readiness of the catalytic
converters ensures low emissions, even in
short-trip operation.
– Reliable operation and good emission control
over a long useful life.
– Please observe the chapter “FUEL ECONOMY”
on Page 184.
Recycling – for a Porsche, this is virtually
an academic question More than two-thirds of all Porsches ever built are
still running.
Just in case recycling is ever necessary, we
take the following precautionary measures:
– Identification of all materials.
– Use of recyclable materials.
– Reusable components designed for simple
removal.
– These reasons result in a further increase in
the recycling rate which is currently 80 per
cent.
Emission control is built in Innovative engine technology combines high en-
gine performance and environmental compatibili-
ty.
The engine diagnosis system electronically moni-
tors the components and systems that affect ex-
haust gases.
This continuous monitoring and fault storage ena-
bles swift, reliable diagnosis and fault detection.
Any fault messages are indicated to the driver by
the “Check Engine” warning light and the on-board
computer.

BOARD COMPUTER” on Page 114.

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 air-
bag deployment, you should always sit back as
far from the steering wheel as is practical,
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
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 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.
fPlease observe the chapter “ENGINE EX-
HAUST” on Page 8.fWhen parked, always set the parking brake.
Move the Tiptronic selector lever to ”P“ or the
gearshift lever to reverse or first gear.
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.
Danger!
Danger of fire in engine compartment due to
burning cigars or cigarettes. Serious perso-
nal injury or death could result from fire in
the engine compartment.
fDo not throw any lit cigars or cigarettes out of
the vehicle.
They can be blown into the air inlets by the air
flow and cause a fire in the engine compart-
ment.
fPlease observe the chapter “ASHTRAY” on Page 138.

If the vehicle was locked before the luggage com-
partment is opened, it is unlocked simultaneously
with the luggage compartment.
In vehicles with seat memory the stored seat and
door mirror positions are automatically set.
The vehicle will be locked again approx. 15 sec-
onds after the luggage compartment is closed if
none of the doors was opened.
Note
Your authorized Porsche dealer can program fur-
ther types of unlocking.
Ty p e 1
The relocking time of the doors can be adjusted to
suit your individual requirements (4 - 120 sec-
onds).
Ty p e 2
The doors stay locked when the luggage compart-
ments are unlocked.
Malfunction of the remote controlThe remote control may not function correctly due
to local radio wave interference. The vehicle will
then not lock properly.
This can be identified by the missing locking
sound and the missing check-back signal of the
hazard warning lights.
If this should occur:
fLock the vehicle with the key in the door.The remote-control standby function
switches off after 7 days If the vehicle is not started or unlocked with the re-
mote control within five days, the remote control
standby function is switched off (to prevent dis-
charging of the car battery).
1. In this case, unlock the driver’s door with the
key at the door lock.
Leave the door closed in order to prevent the
alarm system from being triggered.
2. Press button 1 on the remote control.
The remote control is now activated again.
