2005 PORSCHE BOXSTER ignition

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 Oktane™ 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, 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 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.

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

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 stan-
ding 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 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.
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 122.

Never invite car theft! An unlocked car with the key in the ignition lock in-
vites car theft.
A steering wheel lock and a gong alarm are stan-
dard equipment in your Porsche.
The gong alarm will sound if you open the driver’s
door while the key is still in the ignition lock. It is
your reminder to pull the key out of the ignition
lock and to lock the doors.
Warning!
Any uncontrolled movement of the vehicle
may result in serious personal injury and pro-
perty damage.
Never leave your vehicle unattended with the
key in the ignition lock, especially if children
and/or pets are left unattended in the vehic-
le. They can operate power windows and
other controls. If the engine is left running,
they may accidentally engage the shift lever.
fAlways remove the ignition key.
fAlways set the parking brake.
fLock the doors with the key or with the remote control.
Warning!
Risk of a serious accident.
The steering column will lock when you re-
move the key while you are driving or as the
car is rolling to a stop. You will not be able to
steer the car.
fNever remove the key from the steering lock while you are driving. To protect your vehicle and your possessions
from theft, you should always proceed as fol-
lows when leaving your vehicle:
fClose windows.
fClose convertible top
(with the convertible top open, the passenger
compartment monitoring system is always
switched off).
fLock glove compartment.
fRemove ignition key.
fClose storage tray between the seats.
fRemove valuables (e.g. car documents, tele-
phone, house keys) from the car.
fLock doors.

Keys fPlease observe the chapter “CENTRAL LO-
CKING IN CARS WITH ALARM SYSTEM” on
Page 21.
Two main keys and one spare key are supplied
with your Porsche.
These keys operate all the locks on your vehicle.
fBe careful with your car keys: do not part with
them except under exceptional circumstances.
fTo avoid battery run-down, always remove the
ignition key from the ignition lock.
Replacement keys Replacement car keys can be obtained only from
your authorized Porsche dealer, and this can so-
metimes be very time-consuming.
You should therefore always keep the spare key on
your person.
Keep it in a safe place (e.g. wallet), but under no
circumstances in or on the vehicle.
The key codes of new keys have to be “reported”
to the car control unit by your authorized Porsche
dealer.
The key grip of the spare key can be exchanged
for a main-key grip.
Disabling key codes
If a key is lost, the key codes can be disabled by
an authorized Porsche dealer.
All the remaining car keys are required for this pur-
pose.
Disabling the code ensures that the car can be
started only using authorized keys.
Note
fPlease note that the other locks can still be
opened with the disabled key.
Immobilizer There is a transponder (an electronic component)
in the key grip, containing a stored code.
When the ignition is switched on, the ignition lock
checks the code.
The immobilizer can be deactivated and the engi-
ne started only using an authorized ignition key.
Switching off the immobilizer
fInsert the ignition key into the ignition lock.
If the ignition is left on for more than 2 minutes
without starting the engine, the immobilizer is re-
activated.
fIf this happens, turn the ignition key back to the
3 position before starting the engine.
Please observe the chapter “IGNITION/STAR-
TER SWITCH WITH ANTI-THEFT STEERING
LOCK” on Page 68.
Switching off the immobilizer
fRemove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-
shop visit, do not forget to hand over the so-
cket for the security wheel bolts along with the
car key.
