fAdapt your driving style to the changed condi-
tions.
fConsult an authorized Porsche dealer in order
to remedy a system fault.
fIf the overload-protection function causes the
compressor to switch off, wait for a time until
it has cooled down. The system will function
again as soon as it has cooled sufficiently.
The warning message appears when the control
system is switched off and when the collapsible
spare wheel is being filled. This does not indicate
a fault.
The warning message will go out once these pro-
cedures have been completed.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If you have to work on the engine while it is run-
ning, always put the handbrake on and put the
gearshift lever in neutral or the selector lever
in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), jew-
elry, long hair, hand or fingers cannot get
caught in the fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
For vehicles with air suspension with level con-
trol and height adjustment switch off level con-
trol. Therefore:
Please observe the chapter “RAISING VEHICLE
WITH THE JACK” on Page 256.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Withdraw ignition keys (switch ignition off in ve-
hicles that have Porsche Entry & Drive).fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
fSupplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
Keep these fluids out of children's reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
Power measurementsPower measurements on dynamometers are not
approved by Porsche.

Example of a tire pressure plate ATire Pressure plateDepending on when your vehicle was manufac-
tured, the tire pressure plate on the driver's door
will contain different data.
Information on the tire pressure plate A
A Seating capacity
Maximum number of vehicle occupants, includ-
ing the driver.B Vehicle load limit
Is the maximum total weight limit specified of
the load (passengers and cargo) for the vehi-
cle. This is the maximum weight of passengers
and cargo that can be loaded into the vehicle.
If a trailer is being towed, the trailer tongue
weight must be included as part of the cargo
load. Please observe the chapter “LOADING
INFORMATION” on Page 213.

Practical Tips, Minor Repairs
Removing and storing tiresfAfter changing, adjust tire pressure and torque
wheel bolts diagonally.
Please observe the chapter “CHANGING
WHEELS” on Page 315.
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of rota-
tion and position of each wheel should be marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and perform-
ance are not affected by storage and age is
unfounded.
Chemical additives, which make the rubber elas-
tic, lose their effectiveness over the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires, especially the spare tire,
should be inspected from time to time.Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT“
code number. If, for example, the last three num-
bers read 1204, then the tire was produced in the
12th week of 2004.
fStore tires in a cool and dry place.
fRotate periodically to avoid flat spots.
Snow tiresThe installation of Porsche approved winter tires is
recommended.
Use Porsche approved winter tires for grip on
snow and ice. For optimum performance, stud-
ding can be considered.
Check with your local Motor Vehicle Bureau for
possible restrictions.
Danger!
Risk of loss of control and damage to the
vehicle as well as serious personal injury or
death.
The standard tires profile and rubber mixture
are optimized for wet and dry driving condi-
tions, and may not prove favorable for snow
conditions.
fInstall winter tires before driving in such condi-tions.
Before mounting winter tires, consult with your
Porsche dealer. He has the technical information
necessary to advise you on wheel and tire compat-
ibility.
S n o w t i re s s h o u l d h a v e t h e s a m e l o a d c a p a c i t y a s
original equipment tires and should be mounted on
all four wheels.
Winter tires with studs should be run at moderate
speeds when new in order to give the studs time
to settle.

Practical Tips, Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake com-
ponents.
fUse only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
fFollow instructions issued by the supplier of the chains.
The best possible handling characteristics are
achieved when snow chains are fitted on all four
wheels of the vehicle. However, it is also possible
to fit snow chains on only one axle (preferably the
rear axle).
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f17 mm spacers must always be removed from the rear axle when snow chains are to be fitted.
fFor information on the spacers:
Please observe the chapter “SPACERS” on
Page 314.
For information about removing the spacers:
Please observe the chapter “CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACER”
on Page 323.
fBefore fitting chains, remove accumulated ice
and snow from the wheel well.
fVehicles with snow chains must not be driven
faster than 30 mph (50 km/h).
Different states and countries have varying statu-
tory requirements regarding maximum speed.
fCheck with local authorities for possible
restrictions.
fRemove chains as soon as the roads are free
of ice and snow.

Practical Tips, Minor Repairs
SpacersfUse the spacers only together with wheels
approved by Porsche.
Before having spacers fitted, find out about the
current approval status.
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
Danger!
Risk of accident if the spacers are not re-
moved before mounting 18 inch tires or col-
lapsible spare wheel.
f17 mm spacers are always to be removed be-
fore mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fit-ted correctly. Caution!
