Storing your Porsche If you intend to store yo ur Porsche for a prolonged 
period, please consult your authorized Porsche 
dealer. The staff will be glad to advise you on the 
most suitable and necessary methods. 
f Clean your vehicle thoroughly inside and out-

The under carriage and chassis components 
should be free of dirt and salt deposits. 
f Fill up the fuel tank. 
f Change the oil and oil filter, and run the engine 
for several minutes. 
f Increase the tire pressure to 50 psi (3.5 bar).
It is not recommended to lift the vehicle, due to 
the possibility of corros ion on shock absorber 
piston shafts.
The vehicle should be moved slightly, approxi-
mately every four weeks, to prevent flat spot 
on the tires. 
Climate control 
The air conditioning system should be in good 
working condition and fully charged. 
Windshield/Headlight washer 
f Check and correct antifr eeze/cleaning solution 
level as necessary.  Electrical system 
f
Remove the battery from the vehicle and store 
it in a cool dry place, not on a cement floor. 
When the battery is disconnected, the 
alarm system is deactivated. 
f Recharge the battery every 3 months. If the 
battery remains in the vehicle with the cables 
connected, it is necessary to check, remove 
and recharge the battery every 2-3 weeks. 
Do not fast charge the battery. 
f Please see the chapter “BATTERY” on 
Page 249.
Vehicle interior 
The interior must be dry,  especially in the area of 
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs. 
(500 grams) each placed on the floor carpets. 
Windows, doors and lids must be closed. The air 
vents should be opened.

Practical Tips, Emergency Service
 Danger!
Risk of serious personal injury or death. 
Driving the vehicle with low tire pressure 
increases risk of a tire failure and resulting 
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected 
tires.
f Check tires – including sidewalls – regularly for 
foreign bodies, nicks, cuts, cracks and bulges.
f After driving off road, examine tires for signs 
of damage such as cuts, tears, bulges or for-
eign objects stuck in the  tread. Replace a dam-
aged tire if necessary.
f Cross curb edges slowly and at right angles if 
possible. 
Avoid driving over steep or sharp curbs.
f In cases of doubt, have  the wheel (particularly 
the inner side) checked by an authorized Porsche dealer.
Tire replacements If in doubt, contact  your Porsche dealer.
Use only tire makes and types approved by 
Porsche. 
If you do not use a Porsche recommended 
replacement tire, make sure that you 
purchase your new tires from a reputable tire 
dealer and that the dealer complies with all 
manufacturers warnings for those tires. 
Only tires with the same make and with the 
same specification code (e.g. “N0”, “N1”...) 
can be mounted. 
Before mounting new tires, check with your 
Porsche dealer about the current release 
status. 
Use tires with “ZR” quality standards.  There 
are currently no standards concerning tire 
strength at speeds above 150 mph (240 km/h). 
Tires should be replaced no less than on one axle 
at the time. 
Only tires of the same make and type must be 
used. Mixed tires are not permissible. 
Initially, new tires do not  have their full traction. 
You should therefore drive at moderate speeds 
during the first 60 - 120 miles (100 - 200 km).  If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different 
tread depth of the other tires. 
This happens especially if only rear tires are re-
placed. However, this condition disappears as the 
new tires are broken in. 
f
Please adjust your driving style accordingly.
Installation of new tires sh ould only be done by a 
qualified tire technician. 
Valves 
Rubber valve stems must be replaced every time 
a tire is replaced.
For metal valves, the installation and replacement 
instructions must be observed.
f Use only genuine Porsche metal valves.
f Protect the valve inserts against soiling with 
valve caps.
Soiled valve inserts can cause a gradual loss 
of air.
f Use only plastic valve caps.
