Instruments, On-Board Computer
Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
fIn order to avoid consequential damage to the
engine or emission control system (e.g.
catalytic converter), have the fault diagnosed
and rectified immediately at the nearest autho-
rized Porsche dealer.If the warning light in the instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was
running.
fStop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your
authorized Porsche dealer for service as soon
as possible.
Caution!
If the check engine warning light in the
instrument panel is flashing, serious
catalytic converter damage and power loss
will soon occur.
Prolonged driving with the check engine
warning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
fHave the fault remedied at the nearest authorized Porsche dealer immediately.The central warning light on the instrument panel
lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease see the chapter “INFO WARNING
MESSAGES” on Page 123.
The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.

Wiper Blades Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year
(before and after the cold season) or whenever
wiper performance deteriorates.
Caution!
Risk of damage if the wiper arm accidentally
falls back on to the window.
fAlways hold the wiper arm securely when repla-
cing the wiper blade.
Risk of damage if wiper blades that are
frozen in place are loosened improperly.
fThaw the wiper blades before loosening them.
Maintenance note
fPeriodically clean the wiper blades with
window cleaner, especially after the vehicle
has been washed in a car wash.
We recommend the Porsche window cleaner. If
they are very dirty (e.g. with insect remains),
the windows can be cleaned with a sponge or
cloth.If the wiper blades rub or squeak, this can be as a
result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the winds-
hield. These wax residues can be removed
only by using window cleaner concentrate.
– The wiper blades may be damaged or worn.
fReplace damaged or worn wiper blades as
soon as possible.
fPlease see the chapter “WASHER FLUID” on
Page 170.
fPlease contact your authorized Porsche dealer
for further information.
Changing windshield wiper bladesfPlease follow the separate instructions for
fitting wiper blades as supplied by the
manufacturer.
fWe recommend that you get your authorized
Porsche dealer to replace the wiper blades.
Caution!
Risk of damage.
If a wiper blade is not changed properly, it
can come loose when the car is moving.
fCheck whether the wiper blade is seated
securely.
The wiper blade must engage the wiper arm properly.

remover.
The Porsche range of accessories includes
nonskid floor-mats to protect the carpets in
summer and winter.
Warning!
Risk of an accident resulting in serious
personal injury or death.
fAlways check the movement of the pedals
before driving and make sure that they are not
obstructed by a floor-mat or any other object.
fSecure the floor-mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.
Alcantara fDo not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in. Safety belts If it becomes necessary to clean the belts, you
can use any mild washing agent.
Allow the belts to dry prior to retracting, but avoid
direct sunlight.
fOnly use suitable cleaners.
If unsuitable cleaners are used or any attempt
is made to dye or bleach the belts, the
webbing may be weakened and thus constitute
a safety risk.

Practical Tips, Emergency Service
Changing a WheelfHave the wheel changed at your authorized
Porsche dealer.Note
The tools required for changing a wheel (e.g. jack,
torque wrench, assembly aids) are not supplied as
standard with the vehicle. Your authorized
Porsche dealer will be pleased to advise you.
If a wheel has to be changed, the procedure
described below must be adhered to exactly,
as otherwise the wheel may become loosened,
resulting in damage. In such an event Porsche
will not be held liable.
For application of the required high tightening
torques of the central bolt, a suitable, commer-
cially-available 370 ftlb./500 Nm torque wrench
may be used. Alternatively, a corresponding tool
with torque multiplier (part no. 997.450.323.90)
is available from Porsche Motorsport. When the
torque multiplier is used, the torque should be
reduced in accordance with the tool operating
instructions.
Warning!
Risk of serious personal injury or death. The
car may slip off the jack.
fDue to the high assembly forces, there is a risk
of the car rolling away when using a jack.
Always use a lifting platform if there is one
available.
Risk of damage.
fDo not use an impact wrench.1. Fully apply the handbrake, engage 1st gear
and withdraw the ignition key.
2. Carefully secure the car against rolling away
in both directions, e.g. by placing wedges
under the wheels on the opposite side.
This is particularly important on slopes.
3. Raise the car until the wheel lifts off the
ground. Lift vehicle only at the specified
jacking points.
fPlease see the chapter “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM OR GARAGE LIFT”
on Page 206.
