Maintenance, Car Care
Air CleanerfPlease observe the chapter “EXERCISE
EXTREME CAUTION WHEN WORKING ON YOUR
VEHICLE” on Page 242.
Regular replacement of the filter element is part of
servicing.
fIn dusty conditions, clean the filter element
more frequently and replace if necessary.Particle FilterThe fresh air passing through the particle filter into
the passenger compartment is virtually free of
dust and pollen.
fIf the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air
throughput.
fHave filter replaced by your authorized
Porsche dealer.
Regular replacement of the filter is part of servic-
ing.
Automatic Transmission Fluid The torque converter and the transmission are lu-
bricated with Automatic Transmission Fluid (ATF).
fPlease observe the chapter “CAPACITIES” on
Page 362.
Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
AT F.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary fill-
ing equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
Manual Transmission OilThe transmission oil has to be checked and
changed at the intervals listed in your Maintenance
Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 362.
We recommend that you have the transmission oil
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.

Maintenance, Car Care
UndercoatingThe underside of your car is durably protected
against chemical and mechanical influences.
As it is not possible to exclude the risk of damage
to this protective coating in day to day driving, it
is advisable to have the underside of the car in-
spected at certain intervals - preferably before the
start of winter and again in spring - and the under-
coating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the nec-
essary equipment for applying factory approved
materials. We recommend that you entrust them
with such work and inspections.
Unlike conventional spray oils, undercoating and
rust-proofing compounds based on bitumen or
wax do not attack the sound-proofing materials ap-
plied at the factory.
Danger!
Danger of fire and serious personal injuries.
fDo not apply additional undercoating or rust-
proofing on or near the exhaust manifold, ex-
haust pipes, catalytic converters or heat
shields. During driving the substance used for undercoating could overheat and ignite.
fBefore applying fresh underseal, carefully re-
move deposits or dirt and grease. Once it has
dried, the new undercoating compound forms
a tough protective coating which provides effi-
cient rust-proofing of the floor panels and com-
ponents.
fAlways apply a fresh coating of suitable preser-
vative to unprotected areas after cleaning the
underside of the body, the transmission, the
engine or carrying out repairs to under-body,
engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is driv-
en frequently in areas where salt has been spread
on the roads, the whole engine compartment
should be cleaned thoroughly after the winter to
prevent salt from causing any lasting damage. A
full under-body wash should also be performed at
the same time.

Practical Tips, Minor Repairs
TowingCertain state statutes and local ordinances prohib-
it towing with a chain, rope or even a tow bar. In
addition, damage to your vehicle may result from
improper procedures. Consult your authorized
Porsche dealer for details.Vehicle towingFlat bed towing is the preferred type of towing to
be used on Porsche vehicles. Under certain cir-
cumstances, wheel lifts may be used when the ve-
hicle will not roll.
The vehicle must be towed with all four
wheels off the ground, otherwise damage to
the vehicle may result.Towing hookThe towing hook is contained in the tool kit.
Caution!
Risk of damage to the vehicle.
fUse the towing hook only for an emergency to
remove the vehicle off the road. The towing
hook is to be used only to pull the vehicle onto
the flat bed, tractor or towing aparatus if the
vehicle will roll freely. Under no circumstances
is the vehicle to be secured using the towing
hook.
fNever use the towing hook to tow this or any other vehicle.
Vehicles with Tiptronic
fDo not tow-start vehicles with a Tiptronic
transmission.
The vehicle cannot be tow-started, nor should
this be attempted due to the risk of serious
transmission damage.
Vehicles with manual transmission
Only tow-start vehicles fitted with a catalytic con-
verter when the engine is cold.
If the engine is warm, unburned fuel could damage
the catalytic converter.Front and rear mounting
1. Carefully lever out the appropriate plastic cov-
erA in the bumper with the screwdriver.
The cover is captive and need not be removed
completely.
