Servicing.
In the Boxster models, the generator and
air conditioning system are driven by a
single self-adjusting belt. The drive chains
on the camshafts do not normally require
servicing. With the sole exception of the
spark plugs, the ignition system is also
maintenance-free in normal servicing. In
short, longer service intervals mean long er-
lasting driving pleasure.
initiation of targeted braking. During this

process, any braking by the driver is
boosted to achieve the maximum braking
force that the system is able to provide.
Electrical system recuperation.
For enhanced ef ficiency the Boxster
models are equipped with intelligent elec -
trical system recuperation. The vehicle
bat tery is recharged by the generator
predominantly under braking. Thanks to
this selective recharging, when you
request full driving power the maximum
possible output can be directed straight to
the road.
For increased safet y, the system also
readies the brakes whenever it detects
that the distance from the vehicle is

decreasing. However, the driver should
be prepared to intervene manually if
heavier braking is required. As soon as
the road ahead clears, your vehicle will
accelerate back up to the cruising speed
originally set.
Porsche Active Safe (PAS) issues an audi -
ble and a visual warning if the system
detects that your vehicle is approaching
the vehicle in front too quickly. This is
accompanied by a brief application of
brake force and, where necessary, the

supplemented by application of the

wheel brakes. As long as a gear remains
engaged, the brake pressure is main -

you in making a comfortable, smooth and
roll-free start on an incline. Whenever you
come to halt on an incline, this is detected
automatically and the braking effect

The electric parking brake, which can
be activated and deactivated manually,

nents be professionally inspected and
replaced where necessary after every
track event.
Please note that circuit racing, trackday
use and other forms of performance

driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems,
represents a major reduction in unsprung and rotating masses. The consequence of
this is bet ter road holding and increased
comfort, particularly on uneven roads,
as
well as greater agilit y and improved
handling.
Another key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50
% lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this

To protect the driver and passenger, the
Boxster models are equipped with full -size
airbags, which are inflated in t wo stages
depending on the severit y and t ype of
accident (e.g. frontal or offset frontal). In
less serious accidents, the airbags are

on the roll- over bars for easier fastening.Roll-over protection.
