ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA

Maintenance and Car Care
The warning light on the instrument panel and
the warning message on the multi-function display
alert you to the fact that the washer fluid level
is too low.
f
Add washer fluid at the next opportunity.

Power Steering
Warning!
Risk of accidents. When the engine is
stationary (e.g. when on tow) or the hydraulic
system fails, there is no power steering
assistance available.
Therefore, substantially more force will have
to be exerted to steer the vehicle.
f Exercise extreme care when your vehicle is
being towed.
f Have the fault corrected. Please contact a
qualified specialist workshop. We recommend
that you have an authorized Porsche dealer to
do this work as they have trained workshop personnel and the necessary parts and tools.
Regular checking of hydraulic fluid is part of
servicing.
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the
steering system. Vehicles with Porsche Dynamic Chassis
Control (PDCC)
If the fluid level is too
low, the message “Check
steering oil level” will appe ar on the multi-function
display.
f Have the fluid level checked immediately.

Maintenance and Car Care
271
fStart washing the vehicle by thoroughly
wetting the paintwork and rinsing the heavy
dirt off.
f After washing the vehicle, rinse it thoroughly
with water and rub it dry with chamois-leather.
Do not use the same chamois for rubbing
dry as you use for cleaning the windshield
and windows.
Warning!
Risk of accidents! Reduced or uneven
braking action may be caused by wet
brakes.
f After washing the vehicle, test the brakes
and steering and briefly brake the discs dry.
When doing so, make sure that vehicles travelling behind you are not affected. Cleaning in car washes
Optional add-on parts or parts that project beyond
the contours of the vehi
cle may be damaged by
design features of car washes.
The following parts are particularly at risk:
– Windshield wipers and rear wiper (always switch them off – wiper stalk in
position 0 – to prevent them wiping
unintentionally in intermittent or sensor
operation).
– Exterior mirrors (always fold in).
– External antenna (always unscrew).
– Roof transport system (always remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire height, the greater the risk of damage).
f Please consult the operator before using
automatic car washes.
f All parts not reached by a car wash, such
as door and lid seams or door sills, must
be washed and polished by hand.
Paint careIn order to protect the pa int on your vehicle in
the best possible way against mechanical and
chemical damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
General Notes
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage
the paintwork.
f Do not treat matt-painted components with
preservatives or polishes as these remove
the matt effect.
Preservation
The paint surface becomes dull over time due
to weathering.
f Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve
the paintwork.
This keeps the paint shin y and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating
the paint.

Maintenance and Car Care
Cleaning air bag covers
Danger!
Risk of serious or fatal injury from impaired
operation of the air bag system caused by
incorrect cleaning.
f While it is appropriate to use normal surface
cleaning methods on the interior of your
vehicle, do not undertake deep cleaning of air
bag-related components, such as the
padded covers on the steering wheel,
the underside of the instrument panel,
front seats, roof pillars, roof liners and the
rear interior trim panels, and around the
seat backrest.
f Have your authorized Porsche dealer to clean these components.
Cleaning fabric liningsfFabric linings on pillars, roofliner and sun
blinds, etc. must be cleaned only using
suitable cleaning agents or a suitable dry
foam and a soft brush.
Alcantara careDo not use leather care products to
clean Alcantara.
For regular care, it is sufficient to clean the
cover with a soft brush.
Strong abrasion or rubbing when cleaning will
produce a lasting change to the surface.
Cleaning when lightly soiled
f Wet a soft cloth with water or a neutral
soap solution and wipe off the dirt.
Cleaning when heavily soiled
f Wet a soft cloth with lukewarm water or diluted
white spirit and dab the dirt from the outside
in.Cleaning the seat beltsfUse mild detergent to clean soiled belts.
f When drying, avoid direct sunlight.
f Only use suitable cleaning agents.
f Do not tint or bleach the belts.
The belt fabric could be weakened,
thus affecting safety.
Storing your PorscheIf you wish to keep your Porsche off the road for
a lengthy period, we recommend that you contact
your authorized Porsche dealer.
They will be glad to advise you about the
necessary measures, e.g. corrosion prevention,
care, maintenance and storage.
Further important information on laying up your
Porsche can be found in other sections.
fPlease see the chapter “BATTERY” on
page 303.
