Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If you have to work on the engine while it is run-
ning, always put the handbrake on and put the
gearshift lever in neutral or the selector lever
in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), jew-
elry, long hair, hand or fingers cannot get
caught in the fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
For vehicles with air suspension with level con-
trol and height adjustment switch off level con-
trol. Therefore:
Please observe the chapter “RAISING VEHICLE
WITH THE JACK” on Page 256.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Withdraw ignition keys (switch ignition off in ve-
hicles that have Porsche Entry & Drive).fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
fSupplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
Keep these fluids out of children's reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
Power measurementsPower measurements on dynamometers are not
approved by Porsche.

Radiator fansThe radiator and radiator fans are in the front of
the car.
Warning!
Danger of injury. The fans can start running
as a function of temperature, even with the
engine switched off.
fExercise extreme caution when working in the area of the radiator fans.
Engine OilEngine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the lubri-
cant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil lev-
el at all, even after 600 miles (1000 km) or more.
This is because the oil is gradually becoming dilut-
ed with fuel or moisture, making it appear that the
oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater.If the vehicle is driven at a high rate of speed, cli-
matic conditions are warm, and the load is high,
the oil should be checked more frequently, as driv-
ing conditions will determine the rate of oil con-
sumption.
– The engine in your vehicle depends on oil to lu-
bricate and cool all of its moving parts. There-
fore, the engine oil should be checked regular-
ly and kept at the required level.
– Make it a habit to have the engine oil level
checked with 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 LevelfCheck the oil level regularly. I t i s b e s t t o d o t h i s
when refuelling and before extended journeys.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease observe the chapter “EXERCISE
EXTREME CAUTION WHEN WORKING ON YOUR
VEHICLE” on Page 260.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 124.
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
fKeep engine oil out of children's reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
fAlways protect your skin by washing thorough-ly with soap and water.If the oil level is too low, this is indicated by the oil-
level warning light lighting up on the multi-purpose
display.
fCheck the oil level using the oil dipstick as
soon as possible and add engine oil if neces-
sary.
Note on operation
fIf the engine compartment lid is opened and oil
is not added, the warning message appears
again after approximately 100 km.
Checking the oil level
Warning!
Danger of injury. The radiator fans can start
running as a function of temperature, even
with the engine switched off.
Risk of burning from hot parts in engine com-
partment.
fExercise extreme caution when working on the engine compartment.Conditions for measuring the oil level
correctly
– Vehicle must be level.
– Engine must be switched off and at operating
temperature.
– Before the oil-level measurement, allow the en-
gine oil to flow back into the oil pan for around
3 minutes.
Checking oil level with the oil dipstick
1. Withdraw oil dipstick and wipe it with a clean,
lint-free cloth.
2. Push oil dipstick fully home, withdraw again
and read off the oil level.
The oil level must never fall below or ex-
ceed the “Min.” and “Max.” marks on the
dipstick.
The difference between the marks is approx.
1.6 qt. (1.5 liters).
3. Push oil dipstick in as far as the stop.

Oil changeThe engine oil has to be changed at the intervals
listed in your Maintenance Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 386.
We recommend that you have the engine oil
changed at your Porsche dealer, who has the re-
quired oils and the necessary filling equipment.
If you suspect an oil leak in the engine have your
dealer check it out immediately.
All current engine oils are compatible with each
other, i.e. when making an oil change it is not nec-
essary to flush the engine if you wish to use a dif-
ferent brand or grade of oil.
Since, however, each brand of oil has a special
composition, you should, if possible, use the
same oil brand if it becomes necessary to top up
between oil changes.
Porsche engines have long intervals between oil
changes. Only by using oils approved by Porsche
the needed engine oil performance is guaranteed.If your vehicle is used frequently in stop-and-go
traffic in cold weather, the engine will not always
be properly warmed up.
Condensation from products of combustion may
accumulate in the oil. In this case, it is advisable
to change the oil more frequently so that your en-
gine once again has 100% efficient engine oil.
Engine oil performance classEngine oil is not only a lubricant, but also serves
to keep the engine clean, to neutralize the dirt
which penetrates into the engine through combus-
tion and to protect the engine against corrosion.
To perform these functions, the oil is provided with
additives which have been specially developed for
these functions.
The efficiency of an oil is expressed, for example,
by the API, ILSAC or ACEA classifications.
ViscosityLike all liquids, engine oil is viscous when cold,
and thin-bodied when warm. The viscosity of an oil
is expressed by its SAE class. For cold viscosity
the SAE class is given as a number and the letter
“W“ (as in winter), for hot viscosity the SAE class
is given only as a number.
The viscosity of an oil is, therefore, always the
same if it has the same number of an SAE class.
E.g.: A 5 W-40 oil and a 5 W-50 oil have the same
viscosity when cold; when hot the oil with the
number 40 is thinner than the oil with the number
50.
Oils with two viscosities are called multigrade oils;
oils with only one viscosity are termed single-
grade oils.
The viscosity of the engine oil for your Porsche
has to be chosen according to the ambient tem-
perature given in the engine oil recommendation
table.

Changing the brake fluidBrake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking action.
fTherefore, have the brake fluid changed in ac-
cordance with the change intervals stated in
the booklet “Guarantee and Maintenance”.
The warning light in the instrument panel and the
warning message on the multi-purpose display of
the instrument panel indicate
– indicate the brake level fluid is too low or,
– in conjunction with large pedal travel could in-
dicate a braking-circuit failure.
Note on operation
If the warning lights should light up while driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.
Washer FluidThe washer-fluid reservoir for windshield, rear win-
dow and headlights is located in the engine com-
partment.Warning message on the multi-purpose
displayA message is shown on the multi-purpose display
of the instrument panel if the washer-fluid level is
too low.
In this case, the residual quantity is only around
0.85 quarts (0.8 liter).
fAdd washer fluid at the next opportunity.
Topping off washer fluidThe capacity is approx. 7.9 quarts (7.5 liters).
Clean water is generally not enough to clean the
windows and headlights.
It is advantageous to add a winter cleaner giving
antifreeze protection or a suitable summer clean-
er, depending on the season. Follow the instruc-
tions for the mixture ratio.
fUse only cleaner authorised by Porsche.
1. Please note all the information on the refill
container of the cleaning agent.
2. Open cap of the washer-fluid reservoir.
3. Top off washer fluid and close cap properly.
fDo not use engine coolant anti-freeze or any
other solution that can damage the car’s paint,
in the washer reservoir.
