Break in hints for the first
2,000 miles (3,000 kilometers)The following tips will be helpful in obtaining opti-
mum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, it cannot be completely avoided
that the moving parts have to 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 or
other controls during the break-in period which will
gradually disappear.
Break in brake padsNew 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 com-
pensated 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 consumptionDuring the break-in period oil consumption may be
higher than normal.
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 con-
ditions, as well as the amount of dilution and oxi-
dation of the lubricant.
fMake a habit of checking engine oil with every
fuel filling, add if necessary.

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.

triggered again. This cycle is repeated ten times.Temporarily deactivating ultrasound
passenger compartment monitoring
system and inclination sensorIf people or animals are remaining in the locked ve-
hicle or the vehicle is being transported on a pas-
senger train or ship, for example, the passenger
compartment monitoring system and inclination
sensor must be deactivated.
When locked again, the passenger compartment
monitoring system and inclination sensor are acti-
vated once more.Deactivating

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.

Danger!
Risk of poisoning. Exhaust gas contains
colorless and odorless carbon monoxide
(CO), which is toxic even in low concentra-
tion. Carbon monoxide can cause uncon-
sciousness and even death if inhaled.
fNever start or let the engine run in an en-
closed, unventilated area. It is not recommend-
ed to sit in your car for prolonged periods with
the engine on and the car not moving.
An unattended vehicle with a running engine
is potentially hazardous. If warning lights
should come on to indicate improper opera-
tion, they would go unnoticed.
fNever leave the engine idling unattended.
Danger of fire.
fDo not drive or park your car where combus-
tible materials, such as dry grass or leaves,
can come into contact with the hot exhaust
system.
fIf your car catches on fire for any reason, call
the fire department. Do not endanger your life by attempting to put out the fire.
Starting vehicles with manual
transmissionfOperate footbrake.
fFully depress and hold the clutch pedal.
fPut the gearshift lever in neutral.
fDo not press the accelerator pedal. The engine
control module will provide the correct starting
mixture.
fTurn ignition key to ignition lock position 2.
fDo not operate the starter longer than approx.
10 seconds. If necessary, repeat the starting
procedure after a pause of approx.
10 seconds. Turn the ignition key back to
ignition lock position 3 first.
The first operation of the starter is ended automat-
ically when the engine starts.
If the engine does not start, subsequent starter
operations will not be ended automatically.fDo not warm up the engine when stationary.
Drive off immediately.

engine has reached operating temperature.
fIf battery output is insufficient, jump leads can
be used to start the engine.
fPlease observe the chapter “EMERGENCY
STARTING WITH JUMPER CABLES” on

Note on operation
To ensure a good charge condition for the battery
and thus its ability to start the engine, all electrical
accessories which are not required should be swit-
ched off when the ignition is switched on and when
engine revolutions are low (in stop and go traffic).
