oil level PORSCHE CAYMAN 2006 1.G Owners Manual

2Dear Owner, we would like to thank you for your purchase of a
Porsche Sports car.
Judging by the car you have chosen, you are a mo-
torist of a special breed, and you are probably no
novice when it comes to automobiles.
Remember however, as with any vehicle, you
should take time to familiarize yourself with your
Porsche and its performance characteristics. Al-
ways drive within your own unique capabilities as
a driver and your level of experience with your
Porsche. Ensure that anyone else driving your
Porsche does the same. To prevent or minimize in-
jury, always use your safety belts. Never consume
alcohol or drugs before or during the operation of
your vehicle.
This Owner’s Manual contains a host of useful in-
formation. Please take the time to read this manu-
al before you drive your new Porsche. Become fa-
miliar with the operation of your Porsche car for
maximum safety and operating pleasure. The bet-
ter you know your Porsche, the more pleasure you
will experience driving your new car.
Always keep your Owner’s Manual in the car, and
give it to the new owner if you ever sell your
Porsche. A separate Maintenance Booklet explains how
you can keep your Porsche in top driving condition
by having it serviced regularly.
A separate Warranty and Customer Informa-
tion Booklet contains detailed information about
the warranties covering your Porsche.
For U.S. only:
If you believe that your vehicle has a fault which
could cause a crash, injury or death, you should
immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to
notifying Porsche Cars North America, Inc.
(Porsche Cars N.A.).
If NHTSA receives similar complaints, it may open
an investigation, and if it finds that a safety prob-
lem exists in a group of vehicles, it may order a re-
call and remedy campaign. However, NHTSA can-
not become involved in individual problems be-
tween you and your dealer, or Porsche Cars N.A..
To contact NHTSA, you may either call the Auto
Safety Hotline toll-free at 1(800)424-9393 (or
366-
0123 in Washington, D.C. area) or write to: NHT-
SA, U.S. Department of Transportation, Washing-
ton, D.C. 20590. You can also obtain other infor-
mation about motor vehicle safety from the Hot-
line. Your car has thousands of parts and components
which have been designed and manufactured in
accordance with Porsche’s high standards of engi-
neering quality and safety.
Any alteration of the vehicle may negate or
interfere with those safety features built into
the vehicle. Modifications may be carried out
on your vehicle only if approved by Porsche.
Your Porsche is intended to be used in a safe man-
ner obeying the local laws and in the light of driv-
ing conditions faced by you, and in accordance
with the instructions provided in this Owner’s Man-
ual.
Do not misuse your Porsche by ignoring
those laws and driving conditions, or by
ignoring the instructions in this manual.
Any alteration or misuse of the vehicle can
lead to accidents and severe or fatal person
al injuries.
The fitting of racing tires (e.g. slicks) for sporting
events is not approved by Porsche. Very high cor-
nering speeds can be achieved with racing tires.
However, the resulting transverse acceleration
values would jeopardize the adequate supply of oil
to the engine.
Porsche therefore will not accept any warranty or
accept any liability for damage occurring as a re-
sult of non-compliance with this provision.

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 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 fTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
fCheck all fluid levels such as windshield wash-
er and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unobstruct-
ed.
fCheck air intake slots and area between front
lid and windshield are free of snow and ice, so
the heater and the windshield wipers work
properly. fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe 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.

Display and measurement of the engine
oil level
Caution!
Risk of engine damage.
fRegularly check the oil level after refueling.
fDo not allow the oil level to fall below the mini-mum mark.
Conditions for measuring the oil level
1. It is important to ensure that the vehicle is
horizontal for correct oil level measurement
to occur.
2. Engine is off.
3. Ignition on.Oil return time
Before the oil level is measured, the engine oil has
to have flowed back into the oil pan.
The time taken for the engine oil to flow back de-
pends on the engine temperature and how long
the engine has been stopped.
This waiting time is counted down in the on-board
computer display when the ignition is switched on.
The oil level display segments start to “cycle”.
fIt is best to measure the engine oil level before
embarking on a journey (if the vehicle has not
been driven for an extended period) or with the
engine at operating temperature. Shorter wait-
ing times are achieved in this way.Initiating oil level measurement
fSwitch ignition on (do not start the engine).
The engine-oil level measurement display ap-
pears in the on-board computer.
fAllow waiting time to elapse.
fOnce the measurement has been completed,
you can read off the engine oil level on the seg-
ment display.
– If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
fUnder no circumstances add engine oil.

– If the bottom segment is filled in, the oil level
has reached the minimum mark.
fAdd engine oil immediately.
– If the segment flashes, the oil level has
dropped to below the minimum mark.
fAdd engine oil immediately.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to ap-
prox. 0.4 liter.
fAdd engine oil if necessary.
Please observe the chapter “ENGINE OIL LE-
VEL” on Page 178.
Before adding oil, switch ignition off.
fNever add more engine oil than required
to reach the maximum mark.Oil level measurement during refueling
The oil level is automatically measured during re-
fueling.
Preconditions
1. Ignition is switched off.
2. If the engine is at operating temperature, at
least 5 minutes must elapse between parking
the vehicle and starting the engine.
3. Refueling completed within 15 minutes.
When the ignition is switched on, the engine oil lev-
el is shown on the segment display.
Measurement will be stopped if the above require-
ments are not met.
fStart oil level measurement in the “OIL“ menu
or
fStart oil level measurement by switching on
the ignition.
Failure
A failure of the oil level display is indicated by a
warning message in the on-board computer.The oil level measurement can also be
initiated in the “OIL” menu:
Switching on selection field “D”
fPush operating lever forward.
Initiating measurement
fSelect “OIL” with the operating lever.

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 work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral or the se-
lector lever is in position P or N. 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 engine-compartment blower, 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 place the vehicle on stable supports if
work has to be carried out under the vehicle.
Jacks are not suitable for this kind of work.
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.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
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, 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 in your vehi-
cle.
Please make enquiries before driving abroad.
Power measurements Power measurements on dynamometers are not
approved by Porsche. Working in the engine compartmentHave the necessary work in the engine compart-
ment done by a qualified specialist workshop.
We recommend that you use your authorized
Porsche dealer for carrying out this work.

Maintenance, Car Care
Coolant Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31°F/–35°C.
Only use antifreeze authorized by Porsche. Checking coolant level The expansion tank for the coolant is located in
the rear luggage compartment under the service
flap.
fCheck the coolant level regularly at the trans-
parent window of the expansion tank.
When the engine is cold and the car is level the flu-
id level must lie between the “Min.” and “Max.”
markings.
Topping off coolant
Warning!
Danger of serious personal injury from scald-
ing. Coolant is hazardous to your health, and
may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children’s reach.
fAlso, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open contain-
er. Coolant can be deadly to pets if consumed.
Risk of damage from overflowing coolant.
fTake care while topping off coolant not to soil the luggage compartment or items of luggage.
1. Switch engine off and let it cool.
Please observe the chapter “COOLING SYS-
TEM” on Page 86.2. Press catch button on the service flap and
open flap.
