Before driving off...
Dear Porsche Owner A 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 his/her 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 first f Turn the engine off before you attempt any
checks or repairs on the vehicle.
f Be sure the tires are inflated correctly.
Check tires for damage and tire wear.
f See that wheel bolts are properly tightened
and not loose or missing.
f Check engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
f Check all fluid levels such as windshield
washer and brake fluid levels.
f Be sure the vehicle battery is well charged and
cranks the engine properly.
f Check all doors and lids for proper operation
and latch them properly.
f Check, and if necessary replace worn or
cracked wiper blades.
f See that all windows are clear and unob-
structed.
f Check air intake slots and area between lug-
gage compartment lid and windshield. Ensure
that these areas are free of snow and ice, so
the heater and the windshield wipers work
properly. f
If a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
f Child restraint systems will not fit into the
Sports bucket seat.
Do not install a child restraint system in the
Sports bucket seat.
The Sports bucket seat cannot be equipped
with the LATCH system and thus the airbag
system cannot be manually deactivated.
f Check all exterior and interior lights for opera-
tion and that the lenses are clean.
f Check the headlights for proper aim, and if
necessary, have them adjusted.
f Check under the vehicle for leaks.
f Be sure all luggage is stowed securely.
Emergency equipment It 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.

When the ignition is on the fuel level is displayed.
f Please see the chapter “CAPACITIES” on
Page 271.
If the vehicle’s inclination changes (e.g. going up
or downhill), minor deviations in the indication may
occur. Note
If a small quantity of fuel
is added to a nearly emp-
ty fuel tank, the fuel ga ge cannot measure the add-
ed fuel accurately. The „remaining range“ readout
will also be incorrect.
Warning light “A” When the engine is running, the warning light
of the level gage lights up if less than approx.
2.6 U.S. gallons (10 liters) of fuel remains in the
tank.
Additionally, a warning is displayed in the on-board
computer.
f Fill up at the next opportunity.
Caution!
To prevent damage to the emission control
system and engine.
f Never drive the tank completely out of fuel.
f Avoid high cornering speeds after the warning lights have come on.
f Please see the chapter “EMISSION CONTROL
SYSTEM” on Page 198. If the level gage warning light flashes
, there
has been a system fault.
Additionally, a warning is displayed in the on-board
computer.
There will then be no reserve warning.
f To remedy the fault, go to an authorized
Porsche dealer.

Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
f In order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter), have the fault diagnosed and
rectified immediately at the nearest authorized
Porsche dealer. If the warning light in the
instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was running.
f Stop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your au-
thorized Porsche dealer for service as soon as
possible.
Caution!
If the check engine warning light in the in-
strument panel is flashing, serious catalytic
converter damage and power loss will soon
occur.
Prolonged driving with the check engine war-
ning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
f Have the fault remedied at the nearest authorized Porsche dealer immediately.

If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level checked at every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.Engine Oil Level f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
f Regularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 161.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.3 quarts (1.25 liters).
Each segment of the display corresponds to ap-
prox. 0.42 quart (0.4 liter).
Topping off engine oil
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children’s reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thorough-ly with soap and water. Caution!
Risk of damage from overflowing engine oil.
f Take care while checking and topping up
engine oil not to soil the luggage compartment or items of luggage.
Note
The Check Engine warning light may light up if the
cap of the oil filler opening is opened while the
engine is running.
The oil inlet opening is located in the rear luggage
compartment under the service flap.
1. Measure the oil level and read off the required top-up quantity on the on-board computer.
2. Switch off the engine. 3. Press catch button on the service flap and
open flap.
4. Unscrew the oil filler cap.
5. Add at most 0.5 quarts (0.5 liter) of engine oil at a time.

Refueling Fuel tank capacity is listed under “Capacities”.
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to
health.
fPlease see the chapter “CAPACITIES” on
Page 271. 1.
Important: Stop the engine and switch off the
ignition.
2. Slowly unscrew the tank cap. Hang the tank cap's plastic strap on the hook
on the inside wall of the filler flap.
3. Insert fuel-hose nozzle fully into the filler neck
with the handle of the fuel-hose nozzle facing
down.
4. Do not add further fuel once the correctly op- erated automatic fuel-hose nozzle has
switched off.
Fuel could spray or could run over in warm
temperatures.
5. Replace the tank ca p immediately after
refueling and turn it until you hear it and feel it
engage.
If you lose the tank cap, you must replace it
only with an original part to reduce the
possibility of a fire in the event of a collision.
Caution!
Risk of damage. Decorative film may fade
if it comes into contact with fuel.
f Wipe off any emerging fuel immediately.
Fuel Recommendations Your Porsche is equipped with catalytic convert-
ers and must use UNLEADED FUEL ONLY .
Your engine is designed to provide optimum per-
formance and fuel economy using unleaded premi-
um fuel with an octane rating of 98 RON
(93 CLC or AKI) . Porsche therefore recom-
mends 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 tim-
ing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic
converters. Deposits from leaded fuels will
ruin the converters and make it ineffective
as an emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters.

Maintenance, Car Care
197
Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we rec-
ommend you do not take your car to areas or
countries where unleaded fuel may not be availa-
ble. Octane ratings Octane rating indicates a fuel’s ability to resist det-
onation. Therefore, buying the correct octane gas
is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S. Cost of Living Council oc-
tane rating) or AKI ( anti knock index) octane rating
usually displayed on U.S. fuel pumps is calculated
as research octane numb er plus motor octane
number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI
Fuels containing ethanolDo not use any fuels containing more than 10 per-
cent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems oc-
cur 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. Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
f Never carry additional fuel in portable contain-ers in your vehicle.
Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel from escaping to the atmosphere at
extreme high outside temperatures, when driving
abruptly around curves and when the car is parked
at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.

Practical Tips, Emergency Service

Each tire, including the spare (if provided) should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring (TPM)
that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-in-
flated. Accordingly, when the low tire pressure tell-
tale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TP M is not a substitute for
proper tire maintenance, and it is the driver’s re-
sponsibility to maintain correct tire pressure, even
if under-inflation has not reached the level to trig-
ger illumination of the TP M low tire pressure tell-
tale.
f On vehicles with tire pressure monitoring:
Please see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 151.
When tires are warm, the tire pressure is
increased. f
Never let air out of hot tires.
This could cause the tire pressure to fall below
the prescribed value.
Insufficient tire filling pressure can cause tires to
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.
Overloading
Danger!
Risk of damage to vehicle parts, loss of con-
trol and serious personal injury or death.
f Do not overload your vehicle. Be careful about
the roof load.
f If loading the vehicle also correct the tire pres-
sure. Tire pressure for loaded vehicle can be
found on the tire pressure plate and in the
chapter technical data.
f Never exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous ve-
hicle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.
f Please see the chapter “LOADING INFORMA-
TION” on Page 224.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.
