A- Filler bottle
B- Filler hoseTire sealantThe tire sealant can be used to seal small cuts,
especially in the tire tread.
Sealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
workshop. Even with the tire air-tight, it may be
used only for short journeys in an emergency.On vehicles without level control, the tire sealant
and a compressor with pressure tester can be
found under the cargo floor in the luggage com-
partment.
The tire sealant comprises:
– A filler bottle
– A filler hose
– A valve turner and
– A spare valve insert.
Danger!
Risk of accident.
fUse the tire sealant only in the case of cuts or
punctures no larger than 0.15 in. (4 mm).
fNever use the tire sealant if the rim is dam-aged.
Warning!
The sealant is highly flammable and harmful
to health.
fFire, naked flame and smoking are prohibited
when handling tire sealant.
fAvoid contact with skin, eyes or clothing.
fKeep tire sealant away from children.
fDo not inhale vapours.
In case of contact with the sealant:
fIf sealant gets on the skin or in the eyes,
thoroughly rinse the affected part of the body
off without delay.
fChange soiled clothing immediately.
fVisit a doctor immediately in the event of an
allergic reaction.
fIf sealant was swallowed, thoroughly rinse out
the mouth without delay and drink plenty of
water.
Do not induce vomiting.
See a doctor immediately.

Lifting the vehicle with a jack
Warning!
Danger of injury. The car may slip off the
jack.
fMake sure that no one is in the vehicle when
jacking up and changing a wheel.
fNever jack up the vehicle when it is parked on
a surface that slopes up, down or to the side.
fUse the jack only to raise the car for wheel
changing.
fAlways place the car on stable supports if work
has to be carried out under the car.
The car jack is not suitable for this.
Danger of injury if the level-control system
operates during the wheel change.
fSet the car to jacking mode before raising the
car.
Please observe the chapter “AIR SUSPENSION
WITH LEVEL CONTROL AND HEIGHT ADJUST-
MENT” on Page 236.
Risk of injury and damage if the vehicle is not
secured.
fSecure the vehicle against rolling.
fPlease observe the chapter “SECURING THE VEHICLE AGAINST ROLLING” on Page 295.Maintenance note
The jacking point on the vehicle must be free of
dirt.
1. Slightly loosen the wheel bolts of the wheel to
be changed.
2. Only set up the jack at the rear jacking point
designed for the purpose. The jack foot must
be in contact over its whole area and must be
positioned directly below the head piece.
Use a suitable support if necessary.
3. Hold jack still and wind it up until its head
enters the jacking point on the vehicle.
Only jack vehicle up until the wheel to be
changed is completely off the ground.
4. After lowering the vehicle, remove the jack.

seat).
8. Screw filler connection F onto the tire valve.
Warning!
Danger of injury and risk of damage if the
operating unit is used improperly.
fUse this operating unit only to inflate or to bleed air from the tires of this vehicle.
9. Switch ignition on.
10.Press hand valve Duntil the correct tire pres-
sure is achieved.
Monitor the tire pressure with pressure tester
C during the inflation process.
11.Unscrew the screw coupling from the com-
pressor connection.
12.Unscrew filler connection from the tire valve.
13.Stow tire filler hose in the bag.Note on operation
The compressor features a protective function
against overheating and switches itself off auto-
matically if necessary. The compressor must cool
down for a few minutes after automatic deactiva-
tion.
Reducing tire pressure on vehicles with
air suspensionfOpen air bleed screw E until the correct tire
pressure is achieved.
Monitor the tire pressure with pressure tester
C while correcting the tire pressure.

Electrical SystemIn order to avoid damage and faults in electrical or
electronic systems, electrical accessories should
be installed at your authorized Porsche dealer.
fUse only accessories authorized by Porsche.
Warning!
Risk of short circuit and fire.
Replacing fuses or relays with engine running
or the ignition on could cause electrical
shock.
fDisconnect the battery during all work on the electrical system.
RelaysRelays should be checked or changed only by an
authorized workshop.Alarm system, central lockingThe status of the central locking and alarm system
is not changed by disconnecting the battery.
When the battery is disconnected, the alarm
system ceases to function.
SocketsElectrical accessories can be connected to the
12 V sockets.Note on operation
The sockets and thus the connected electrical ac-
cessories function even if the ignition is swi tched
off or the ignition key is withdrawn.
If the engine is not running and the accessories
are switched on, the vehicle battery will be
discharged.

Changing fusesIn order to prevent damage to the electrical
system due to short circuits and overloads, the in-
dividual circuits are protected by fuses.
One fuse box is in the engine compartment. Two
additional fuse boxes are located in the outer ends
of the dashboard.
1. Switch off the consumer with the defective
fuse. Before replacing a fuse, switch off all
electrical consumers and remove the ignition
key.
2. Open the fuse-box lid.
3. Remove the corresponding fuse from its slot to
check it using the plastic gripper.
A blown fuse can be identified by the melted
metal strip.
4. Replace only with fuses of the same rating.
Note
If a fuse blows repeatedly, please consult an au-
thorized Porsche dealer immediately, so that the
short circuit can be located and corrected.
Never try to “repair“ fuses: you may cause serious
damage to other parts of the electrical system.
