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.

Maintenance, Car Care
Fuels containing MMTSome North American fuels contain an octane en-
hancing additive called methylcyclopentadienyl 
manganese tricarbonyl (MMT).
If such fuels are used, your emission control sys-
tem performance may be negatively affected.
The check engine warning light on your instrument 
panel may turn on. 
If this occurs, Porsche recommends you stop us-
ing fuels containing MMT.
Portable Fuel Containers
 Danger!
Portable fuel containers, full or partially 
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
fNever carry additional fuel in portable contain-ers in your vehicle.
Fuel Evaporation ControlFuel tank ventingThe evaporation chamber and the carbon canister 
prevent fuel from escaping to the atmosphere at 
extreme high outside temperatures, when driving 
abruptly around curves and when the car is parked 
at an incline or in any other nonlevel position.Vapor control system and storageWhen the fuel tank is filled, vapors are collected in 
the evaporation chamber by a vent line leading the 
vapors to the carbon canister where they are 
stored as long as the engine does not run.Purge systemWhen the engine is running, the fuel vapors from 
the canister will be mixed with fresh air from the 
ambient air of the canister. This mixture will be di-
rected to the intake air housing by the tank vent 
line, mixed with the intake air and burned during 
normal combustion.

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.

Battery
 Danger!
Risk of short circuit and fire.
fObserve all warning notes on the battery.
fDisconnect the battery during all work on the 
electrical system.
fDo not lay tools or other metal objects on the 
battery as they could cause a short circuit 
across the battery terminal.
Hydrogen gas generated by the battery 
could cause an explosion, resulting in severe 
personal injuries.
fDo not expose the battery to an open flame, 
electrical spark or a lit cigarette.
Risk of explosion
fDo not wipe the battery with a dry cloth.
fBefore touching the battery, discharge any 
static electricity by touching the vehicle.
Risk of severe personal injury and damage to 
the fabric, metal or paint.
fWear eye protection.
fDo not allow battery acid to come in contact 
with your skin, eyes, fabric or painted surfac-
es.fIf you get electrolyte, which is an acid, in your 
eyes or on your skin, immediately rinse with 
cold water for several minutes and call a doc-
tor.
fSpilled electrolyte must be rinsed off at once 
with a solution of baking soda and water to 
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds, 
chemicals known to the State of California to 
cause cancer and reproductive harm.
fAlways protect your skin by washing thorough-
ly with soap and water.
Charge stateA well charged battery will not only prevent start-
ing problems but will also last longer.
In order to avoid unintended battery 
discharge
fSwitch off unnecessary electrical loads in city 
traffic, on short trips or in a line of traffic.
fAlways remove the ignition key from the igni-
tion switch when leaving the vehicle or
switch ignition off in vehicles with Porsche En-
try & Drive.
fAvoid using the Porsche Communication 
Management system and the audio system 
when the engine is not running.
Battery carefEnsure that battery is securely mounted.
fKeep terminals and connections clean and 
properly tightened. Corrosion can be prevent-
ed by coating the terminals and connections 
with petroleum jelly or silicone spray.
fEnsure that vent caps are securely tightened to 
prevent spillage.
Checking the electrolyte fluid level
(only on low-maintenance batteries)
Generally, the electrolyte level must be checked 
more often in summer than in the winter, and more 
often when driving long distances.
fWhen adding water, use only clean containers. 
In no case may alcohol (e.g. window cleaner 
residues) be permitted to enter the battery.
fUnscrew and open the filler vent caps of each 
cell.
With the car on a level surface, the fluid level 
should meet the indicator mark in each cell.
fIf necessary, top up with distilled water. Do not 
use acid. Only fill up to the mark, otherwise the 
electrolyte will overflow when the battery is be-
ing charged and cause damage.

Winter operationDuring the winter months, battery capacity tends 
to decrease as temperatures drop. Additionally, 
more power is consumed while starting, and the 
headlights, heater, rear window defogger, etc., 
are used more frequently.
Let your Porsche dealer test the battery's capaci-
ty before winter sets in.Vehicle storageIf the car stands for long periods in the garage or 
workshop, the doors and lids should be closed. 
fRemove the ignition key and, if necessary, dis-
connect the battery. 
Notes on operation
fWhen the battery is disconnected, the alarm 
system ceases to function.
If the vehicle was locked before the battery 
was disconnected, the alarm will be triggered 
when the battery is reconnected.
To deactivate the alarm system:
fLock the vehicle and unlock it again.Maintenance note
Even if you put your vehicle out of operation, the 
battery still discharges. 
The battery will discharge more quickly if your ve-
hicle is not driven on a daily basis over a distance 
of several miles. The more often you drive your ve-
hicle, and the longer the distance driven on each 
trip, the more opportunity the vehicle‘s charging 
system will have to recharge the batteries.
fTo preserve its efficiency, charge the battery 
about every 6 weeks.
fCheck the battery acid level and top off with 
distilled water if necessary.
fStore a battery that has been removed in a 
dark, cool place, but not subject to freezing.
Putting vehicle into operationAfter the battery is connected or charged, the 
PSM warning light lights up on the instrument pan-
el and a message appears on the multi-purpose 
display of the instrument panel to indicate a fault.
This fault can be remedied with a few simple 
steps:
1. Start the engine.
To do this, turn the ignition key or the control 
unit (on vehicles that have Porsche Entry & 
Drive) to ignition lock position 2 twice.2. Perform a few steering movements and drive 
a short distance in a straight line until the PSM 
warning light goes out and the message is 
erased from the memory of the multi-purpose 
display of the instrument panel.
3. If the warnings does not go out, then:
