Coolant Level

l>
Please observe thechapter "EXERCISE EX-
TREME CAUTION WHENWORKING ONYOUR
VEHICLE" onPage 112.
The cooling systemisfilled atthe factory witha
permanent coolant.
It provides year-round protectionfromcorrosion
and freezing downto-31°F
I-35°C
(Nordiccoun-
tries -40°F/-40°Cl.

l>
Only useantifreeze authorized byPorsche.
Checking
coolantlevel

The expansion tankwithitsfiller orifice isinthe en-
gine compartment.

l>
Check thecoolant levelregularly throughthe
transparent expansiontank.
When theengine iscold andthecar islevel the
fluid level must liebetween the"MIN" and"MAX"
markings.

Topping offcoolant

/!\
Warning!
Danger ofserious personal injuryfromscald-
ing. Coolant ishazardous toyour health, and
may befatal ifswallowed.

l>
Donot open thecap ofthe expansion tank
while theengine ishot.

I>
Allow theengine tocool down before opening
the cap andprotect yourhands, armsandface
from anypossible escapeofhot coolant.

l>
Keep coolant outofchildren's reach.

l>
Also, keepcoolant awayfromyourpets.
They canbeattracted toitshould therebea

Switch engineoffand letitcool.
Please observe thechapter "COOLING SYS-
TEM" onPage 62.
2. Cover theexpansion tankcapwith athick rag.
Open capslowly andcarefully andallow over-
pressure toescape.
Then unscrew capcompletely.
3. Only addamixture ofantifreeze andwater in
equal parts, anddonot exceed the"MAX"
mark.

Antifreeze incoolant:

50% gives protection downto
-31°F/-35°C

60% gives protection downto-58°F
I-50°C

4. Screw capfirmly on.
If in an emergency purewater hasbeen added,
the mix ratio must becorrected atan authorized
Porsche dealer.
Marked lossofcoolant indicates leakageinthe
cooling system.
The cause should immediately beremedied atan

Engine
Oil

Engine oilconsumption

It is normal foryour engine toconsume oil.
The rate ofoil consumption dependsonthe quality
and viscosity ofoil, the speed atwhich theengine
is operated, theclimate, roadconditions aswell
as the amount ofdilution andoxidation ofthe
lubricant.
If the vehicle isused forrepeated shorttrips, and
consumes anormal amount ofoil, the engine oil
measurement maynotshow anydrop inthe oil
level atall, even after600miles (1000 km)or
more. Thisisbecause theoilisgradually becom-
ing diluted withfuelormoisture, makingitappear
that theoillevel hasnotchanged.
The diluting ingredients evaporateoutwhen the
vehicle isdriven athigh speeds, ason anexpress-
way, making itthen appear thatoilisexcessively
consumed afterdriving athigh speeds.
If the conditions youdrive yourvehicle inare
dusty, humid, orhot, thefrequency ofthe oil
change intervals shouldbegreater. If
the vehicle isdriven atahigh rateofspeed,
climatic conditions arewarm, andtheload ishigh,
the oilshould bechecked morefrequently, as
driving conditions willdetermine therate ofoil
consumption.
- The engine inyour vehicle depends onoilto
lubricate andcool allofits moving parts.
Therefore, theengine oilshould bechecked
regularly andkept atthe required level.
- Make ita habit tohave theengine oillevel
checked withevery fuelfilling.
- The oilpressure warninglightisnot anoillevel
indicator.
The oilpressure warninglightindicates serious
engine damage maybeoccuring whenlit,ifen-
gine rpmisabove idlespeed.

Brake Fluidlevel

I>
Please observe thechapter "EXERCISE EX-
TREME CAUTION WHENWORKING ONYOUR
VEHICLE" onPage 112.

I>
Use only new(unused) OriginalPorsche
brake fluid.

Warning!
Brake fluidishazardous toyour health, and
may befatal ifswallowed.
Brake fluidalsoattacks paintwork.

I>
Keep brake fluidoutofchildren's reach.

I>
Take carewhile topping offbrake fluidnotto
soil theluggage compartment oritems oflug-
gage .
Checking thebrake fluidlevel
The reservoir forthe hydraulic brakingsystems is
in the luggage compartment.

I>
Check thebrake·fluid levelregularly atthe
transparent reservoir.
The fluid level should always liebetween the"MIN"
and "MAX" marks.
A slight decrease inthe fluid level duetowear and
automatic readjustment ofthe disc brakes isnor-

mal.
If, however, thefluid level fallsmarkedly orbelow
the "MIN" mark, thebraking systemmayhave
developed aleak.

I>
Have thebraking systemchecked immediately
at an authorized Porschedealer. Changing
thebrake fluid
Brake fluidabsorbs moisture fromtheairover
time. Thisaccumulation ofwater lowers theboil-
ing point and,under certain operating conditions,
can affect thebraking action.
Therefore havethebrake fluidchanged inaccor-
dance withthechange intervals statedinthe
brochure "Maintenance".

Octane ratings

The CLC orAKI octane ratingisusually lowerthan
the RON rating:
For example: 95RON equals 90CLC orAKI
Unleaded

continental U.S.andCanada. Therefore, werec-
ommend youdonot take your cartoareas or
countries whereunleaded fuelmay notbeavail-
able.
Octane ratingindicates afuel's ability toresist det-
onation. Therefore, buyingthecorrect octanegas
is important toprevent engine"damage".
The RON octane ratingisbased onthe research
method. TheCLC (U.S. CostofLiving Council oc-
tane rating) orAKI (antiknock index)octane rating
usually displayed onU.S. fuelpumps iscalculated
as research octanenumber plusmotor octane

Fuels
containing MMT

Some NorthAmerican fuelscontain anoctane en-
hancing additive calledmethylcyclopentadienyl
manganese tricarbonyl(MMT).

If
such fuels areused, youremission controlsys-
tem performance maybenegatively affected.
The check engine warning lightonyour instrument
panel mayturnon.

If
this occurs, Porsche recommends youstop us-
ing fuels containing MMT.
Portable FuelContainers

/!\
Danger!
Portable fuelcontainers, fullorpartially
empty, mayleakcausing anexplosion, orre-
sult infire incase ofan accident.

D>
Never carryadditional fuelinportable contain-
ers inyour vehicle.

Fuels
containing alcoholandether

Some areasofthe U.S. require oxygenated fuels
during certain portions ofthe year. Oxygenated fu-
els are fuels which contain alcohols (suchasmeth-
anol orethanol) orether (such asMTBE).
Under normal conditions, theamount ofthese
compounds inthe fuel willnot affect driveability.
You may useoxygenated fuelsinyour Porsche,
provided theoctane requirements foryour vehicle
are met. Werecommend, however,tochange to
a different fuelorstation
if
any ofthe following
problems occurwithyour vehicle:
- Deterioration ofdriveability andperformance.
- Substantially reducedfueleconomy.
- Vapor lockandnon-start problems, especially
at high altitude orathigh temperature.
- Engine malfunction orstalling.
