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

Tires should beinflated atcorrect pressure.
~ Always monitor yourfuelconsumption.
~ Drive smoothly, avoidabrupt changes inspeed
as much aspossible.
~ Avoid jackrabbit startsandsudden stops.
~ Donot drive longer thannecessary inthe lower
gears. Shifting intoahigher gearearly without
lugging theengine willhelp save fuel.
~ Prolonged "warmup"idling wastes gas.Start
the vehicle justbefore youareready todrive.
Accelerate slowlyandsmoothly.
~ Switch offthe engine ifstationary forlonger
periods.

Operating
YourPorsche inother
Countries

Government regulationsinthe United States and
Canada requirethatautomobiles meetspecific
emission regulations andsafety standards. There-
fore, carsbuiltforthe U.S. andCanada differfrom
vehicles soldinother countries.
If you plan totake your Porsche outsidetheconti-
nentallimits ofthe United States orCanada, there
is the possibility that
- unleaded fuelmay notbeavailable;
- unleaded fuelmay have aconsiderably lower
octane rating.Excessive engineknockandse-
rious damage toboth engine andcatalytic con-
verters couldresult;
- service maybeinadequate duetolack ofprop-
er service facilities, toolsordiagnostic equip-
ment;
- replacement partsmaynotbeavailable orvery
difficult toget.

Porsche cannotberesponsible forthe
mechanical damagethatcould result
because ofinadequate fuel,service orparts
availability.

If you purchased yourPorsche abroadandwant to
bring itback home, besure tofind outabout ship-
ping andforwarding requirements, aswell ascur-
rent import andcustoms regulations.

spread onthe roads.
The longer salt,road dustandindustrial dust,
dead insects, birddroppings orsubstances from
trees (resin, pollen) areallowed toremain onthe
bodywork, themore serious istheir harmful ef-
fect.
New cars should bewashed carefully withplenty
of clear water toprotect thenew paint work. Dark
paint finishes showupthe smallest ofsurface
damage (e.g.,scratches) morereadily thanlighter
colors.
Dark colors arealso more susceptible toscratch-
ing because ofthe composition oftheir pigments
and require particularly carefulpaintcare.

After washing, rinsethecarwith plenty ofwa-
ter and then drywith achamois leather.
Do not use thesame chamois leatherfordry-
ing asyou useforcleaning thewindshield and
windows.

/!\
Warning!
Moisture whichgetsontothe brakes during
a car wash canreduce braking efficiency or
make thebrakes pullunevenly whichcould
increase thedanger ofan accident, causing
serious personal injuriesordeath.

D-
Always applythebrakes afew times after
washing thecartotest braking efficiency and
dry the brake discs.
When doingthis,take care nottohamper other
road users behind you(traffic conditions per-
mitting),
