Maintenance, Car Care
Wiper Blades Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year (be-
fore and after the cold season) or whenever
wiper performance deteriorates.
Caution!
Risk of damage if the wiper arm accidentally
falls back on to the window.
f Always hold the wiper arm securely when re-
placing the wiper blade.
Risk of damage if wiper blades that are fro-
zen in place are loosened improperly.
f Thaw the wiper blades before loosening them.
Maintenance note
f Periodically clean the wiper blades with win-
dow cleaner, especially after the vehicle has
been washed in a car wash.
We recommend the Porsche window cleaner. If
they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth. If the wiper blades rub or squeak, this can be as a
result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the wind-
shield. These wax residues can be removed
only by using window cleaner concentrate.
– The wiper blades may be damaged or worn.
f Replace damaged or worn wiper blades as
soon as possible.
f Please see the chapter “WASHER FLUID” on
Page 210.
f Please contact your authorized Porsche dealer
for further information. Changing windshield wiper blades

f We recommend that you get your authorized
Porsche dealer to replace the wiper blades.
Caution!
Risk of damage.
If the wiper blades are not changed properly, they
can come loose when the car is moving.
f Check that the wiper blades are seated
securely. The wiper blades must engage properly in the wiper arm.

Practical Tips, Emergency Service
Battery care fEnsure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened.
Corrosion can be prevented by coating the ter-
minals and connections with petroleum jelly or
silicone spray.
f Ensure that vent caps ar e securely tightened to
prevent spillage.
Checking the electrolyte fluid level
The acid level should be checked more frequently
by a qualified specialist workshop during the sum-
mer months and in predominantly warm countries. Battery charging
Automotive batteries lose their efficiency when
not in use.
The charge available in your battery can be meas-
ured with a battery hydrometer.
We recommend that the battery voltage be tested
by your authorized Porsche dealer who has the ap-
propriate equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allows
rapid formation of sul-
fates, leading to premature deterioration of the
plates.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
f Charge battery in a well ventilated area.
f Never charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
f If you get electrolyte, wh ich is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-tor. Slow battery charging
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
1. Always observe the instructions of the charger
manufacturer.
Depending on the type of charger, the battery
may have to be disconnected.
In this case, always disconnect the negative
lead first, and then the positive lead – risk of
short circuit!
Reconnect the leads in reverse order.
2. Before charging, cold batteries must be warmed up indoors.
3. Frozen batteries must be thawed out first before being charged.
4. When charging, ensure that there is adequate ventilation.
5. Connect the charger to the battery. Only plug into the mains and switch the
charger on when it is connected up correctly.
6. Switch on the charger.
7. After charging, switch off the charger first and then disconnect it.
