Operation, Safety

ABS Brake System
(Antilock Brake System)The ABS system represents a major contribution
to the enhancement of active safety in your vehi-
cle. This system prevents the wheels from locking
in a panic stop on almost all road surfaces.
With the ABS system in your vehicle, the
following areas are enhanced:
Steering, vehicle remains steerable under all
braking forces when ABS is engaged.
Good directional control , no swerving caused
by locking of wheels under braking conditions.
Shorter stopping distance , stopping distances
are usually reduced because controlled braking is
maximized.
Prevention of wheel lock up , no brake- induced
sliding and thus no localized tire wear from emer-
gency braking.
The crucial advantage of the ABS system over a
conventional brake system is in the area of main-
taining directional control and maneuverability of
the car in emergency situations.
Warning!
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with ABS.
The risk of accidents due to inappropriate
speed cannot be reduced, even by the ABS.
The driver bears the responsibility for all
driving maneuvers.
f Adapt your driving style to the prevailing road
and weather conditions.
f Obey all traffic laws.
Other vehicles not equipped with the ABS
system may not be able to maintain control,
especially on wet or poor road surfaces and
thus may be more likely to impact you from
behind.
f To minimize that risk, use your ABS system to
increase your ability to maneuver to avoid dan-
gerous situations and not merely to try to stop in the shortest distance possible.
Operation of the ABS systemA wheel speed sensor is mounted to each of the
four wheels. If wheel lock -up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips.
If braking forces approach the wheel lock-up point
for all wheels (panic brak ing) the ABS system will
intervene to provide a rapid rythmic braking. The
proper operation of ABS is perceived by the driver
as a pulsating brake pedal in conjunction with au-
dible noise and perhaps some vibration.
f If you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
f If full braking should be necessary, press the
brake pedal all the wa y down throughout the
entire braking procedure, regardless of the pul-
sating pedal. Do not ease up on pressure ap-
plied to the pedal.
The functional readiness of all the main electrical
components of the ABS is checked by an
electronic monitoring system both before and
while you drive.

The available items and displays in the on-board
computer depend on the equipment of your vehi-
cle. For this reason it is possible that some of the
items and displays shown here are not available in
your on-board computer. Basic setting
– Central display: .... Radio station
The central line

be selected in the SET menu.

f Push operating lever up or down
(selection field D must be switched off).
The following displays can be called step by step:
– Average speed (ø mph),
– Average consumption (ø mpg),
– Range on remaining fuel (mls ),
– Tire pressure
– Navigation information (if activated in the SET menu).
Note
The values “Average speed”, “Average consump-
tion” and “Daily trip mileag e” can be reset to zero
in the SET menu.

Tire Pressure MonitoringfPlease see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.
The Tire Pressure Monitoring continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for the Tire
Pressure Monitoring take place on the on-board
computer.
However, you must still adjust the tire pressure on
the wheel. f
The driver is responsible for filling the tires
correctly and making the correct settings on
the on-board computer.
The Tire Pressure Monitoring offers the following
functions:
– Display of the actual ti re pressure while the
vehicle is in motion.
– Display of the deviation from the required pressure (refilling pressure).
– Display of currently set tire size and type.
– Tire pressure warnings in two stages.
Warning!
f Despite the advantages offered by the Tire
Pressure Monitoring, it is still the driver’s re-
sponsibility to update the corresponding set-
tings in the on-board computer and maintain
the pressure in the tires.
Low tire pressure reduces the road safety of
the vehicle and destroys the tire and wheel.
f When a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the
damage with a tire sealant.
f Do not by any means continue to drive with
damaged tires.
f Sealing the tire with tire sealant is only an
emergency repair, so you can drive to the next
authorized Porsche dealer. The maximum per-
mitted speed is 50 mph (80 km/h). f
Do not drive with tires whose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by an authorized
Porsche dealer.
f Damaged tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.
f If a fault occurs in the Tire Pressure Monitoring
(e.g. defective wheel tr ansmitter), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored at all or
will be monitored only partially by defective
Tire Pressure Monitoring.
f Tires lose air over time without a tire defect
being present. A tire pressure warning will then
appear in the on-board computer display.
Correct the tire pressure at the next oppor-
tunity.
f The Tire Pressure Monitoring gives a warning
about tire damage due to natural pressure loss
as well as about a gradual loss of pressure due
to foreign objects.
The Tire Pressure Mnitoring cannot warn you
about tire damage that occurs suddenly (e.g.
flat tire due to abrupt external effects).

Tire pressure function of the on-board
computer
The tire pressure function of the on-board
computer
displays the tire pressures (actual
pressure) dependent on temperature in the four
wheels.
You can watch the tire pressure rise as the
temperature increases while driving.
This display is only for information.
f Under no circumstances should the tire
pressures be changed based on this display.
Warning!
This display is for informational purposes
only. Under no circumsta nces should the tire
pressures be changed based on this display.
Changing the tire pressure to incorrect
pressures could adversely affect the perfor-
mance, driving character istics, and safety of
your vehicle.
f Maintain tire pressures according to the units
indicated on the tire pressure plate, located on the drivers side door of the vehicle.
Displaying the tire pressure function of the
on-board computer
f Push operating lever up or down until the tire
pressure function of the on-board computer
appears.
(The selection field must be switched off.)Pressure info in tire pressure menu
In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 18 °F (10 °C)
change in temperature.
The Tire Pressure Monitoring takes this relation-
ship between tire pressure and temperature into
account.
f
Please see the chapter “PRESSURE INCREASE
AS THE RESULT OF TEMPERATURE
INCREASE” on Page 160.
You can read the tire pressures to be
corrected in this display.

The tire pressure to be corrected (refill pressure)
is indicated on the displayed wheel.
Example: If “ –1.5 psi (–0.1 bar)” is displayed,
1.5 psi (0.1 bar) must be added to this tire.
Note
The tire pressure menu can only be called up when
the vehicle is stationary.

fPush operating lever forward in order to switch
on the selection field.
f Select “TPM” with the operating lever.
f Push operating lever forward.

Note
After the ignition is switch ed on, it can take up to
approx. 1 minute before all tire pressures are
displayed. Dashes (“-.-”) appear instead of the tire
pressures. Tire type info in Tire pressure menu
