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
