Technical ModificationsfModifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are
from the Porsche Tequipment range or are
tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversel y affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in the accessory market, it is not possible for
Porsche to inspect and approve every one.
f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.
Radiator fanFor information on radiator fans:
fPlease see the chapter “RADIATOR FANS” on
page 258.
Warning!
Danger of injury. After the ignition is
switched off, the engine compartment and
coolant temperatures are monitored for
approx. 30 minutes. During this period, and
depending on temperature, the radiator fan
may continue to run or start to run.
f Carry out work in these areas only with the engine off and exercise extreme caution.
Measurements on test standsPerformance test
Performance tests on roller-type test stands are
not approved by Porsche.
Brake tests
Brake tests must be performed only on roller-type
test stands.
The following limit values must not be exceeded
on roller-type test stands:
– Test speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds
Testing the electric parking brake
Electric parking brake tests on the brake test
stand must only be performed with the ignition
switched on and with the manual gearshift lever in
neutral or the Porsche Doppelkupplung selector
lever in position N.
The vehicle switches auto matically to brake test
stand mode, in which the electric parking brake
can be tested.
The message “Electric parking brake in service
mode” appears on the multi-function display in the
instrument panel.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire
vehicle must be lifted and the wheels must be free
to turn.

Maintenance and Car Care
271
fStart washing the vehicle by thoroughly
wetting the paintwork and rinsing the heavy
dirt off.
f After washing the vehicle, rinse it thoroughly
with water and rub it dry with chamois-leather.
Do not use the same chamois for rubbing
dry as you use for cleaning the windshield
and windows.
Warning!
Risk of accidents! Reduced or uneven
braking action may be caused by wet
brakes.
f After washing the vehicle, test the brakes
and steering and briefly brake the discs dry.
When doing so, make sure that vehicles travelling behind you are not affected. Cleaning in car washes
Optional add-on parts or parts that project beyond
the contours of the vehi
cle may be damaged by
design features of car washes.
The following parts are particularly at risk:
– Windshield wipers and rear wiper (always switch them off – wiper stalk in
position 0 – to prevent them wiping
unintentionally in intermittent or sensor
operation).
– Exterior mirrors (always fold in).
– External antenna (always unscrew).
– Roof transport system (always remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire height, the greater the risk of damage).
f Please consult the operator before using
automatic car washes.
f All parts not reached by a car wash, such
as door and lid seams or door sills, must
be washed and polished by hand.
Paint careIn order to protect the pa int on your vehicle in
the best possible way against mechanical and
chemical damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
General Notes
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage
the paintwork.
f Do not treat matt-painted components with
preservatives or polishes as these remove
the matt effect.
Preservation
The paint surface becomes dull over time due
to weathering.
f Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve
the paintwork.
This keeps the paint shin y and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating
the paint.
