2008 PORSCHE CAYENNE park assist

Chassis
Exceptional power requires accurate direction.
Steering.Tough for off road, light for the track, stylish for any terrain.
Wheels.
The electrically adjustable steer-
ing column has a driver-selectable
‘Easy Entry’ function, which raises
the steering wheel towards the
dashboard whenever you enter
or leave the car. The comfort and
sports seat options (standard on
Cayenne GTS and Cayenne Turbo)
have a comfort memory package
that stores your preferred
wheel position as well as seat
and exterior mirror settings.
The steering column consists of
multiple collapsing sections linked
by three universal joints. A special
deformation element offering
70 mm of travel provides a high
level of safety in the event of front
impact.
Servotronic.
Servotronic is a speed-sensitive
power steering system available
as an option on all Cayenne
models.
At higher speeds, the steering
becomes firmer, inputs are more
precise and driver comfort is
greatly enhanced.
At lower speeds, it enables easy
manoeuvrability and parking. For optimum manoeuvrability, on
and off road, all Cayenne models
have variable-ratio steering
and special valve settings on
the power-steering system. Lock-
to-lock travel is a modest
2.65 turns, while the turning
circle is just 11.7 metres.
The steering wheel can be adjusted
by 50 mm for reach and 40 mm
for height. Both adjustment options
are electrically assisted on
the Cayenne GTS and Cayenne
Turbo. Electric adjustment is also
available as an option on the
Cayenne and Cayenne S as part
of the optional comfort or sports
seat package (each with comfort
memory package). The optional
padded steering wheel (standard
on Cayenne GTS) brings added
sporting style to each model.
the multi-purpose display in the
instrument cluster. Standard wheel fitments are as
follows: 17-inch Cayenne alloys on
the Cayenne, 18-inch Cayenne S II
on the Cayenne S, 21-inch
Cayenne Sport on the Cayenne
GTS and 19-inch Cayenne Design
on the Cayenne Turbo.
For a more personal touch, you
can choose from a range of
wheel options (see page 160).
Tyre Pressure Monitoring
(TPM).
The optional TPM warns of any
drop in pressure via the on-board
computer display. In addition,
the driver can check the individual
pressures in all four wheels via

by a tandem booster and large
brake master cylinder. The foot-
operated parking brake uses a
duo-servo system mounted on
each of the rear discs.
Porsche Stability Management
(PSM) features two additional
brake functions: electronic brake
Porsche braking systems are
renowned worldwide as the
benchmark in performance and
stability. The Cayenne models
continue this tradition, offering
excellent deceleration – even
when fully laden with five adult
Porsche has always been synonymous with acceleration.
That’s only half the story.
Braking system.
All Cayenne models have internally
vented discs all round. This simple
yet highly effective design ensures
consistent brake performance.
The front disc dimensions
(diameter/thickness) are 330 mm /
32 mm on the Cayenne, 350 mm /
34 mm on the Cayenne S and
Cayenne GTS, and 380 mm /
38 mm on the Cayenne Turbo.
All models have six-piston monobloc
aluminium brake calipers at the
front and four-piston equivalents
at the rear. The Cayenne Turbo
has a new and more powerful
braking system to offset its higher
performance. The fixed calipers on
the Cayenne Turbo are noticeably
larger and have a striking red
paint finish. The calipers on the
Cayenne GTS are also red, while
the Cayenne S has silver and the
Cayenne black. Braking is assisted

and all-wheel brake assist. See
page 98 for more information
on PSM.
All brake pads are fitted with
individual wear sensors. When new
pads are required, a warning light
is illuminated in the instrumentcluster. The brake lines serving
each of the rear calipers feature
special off-road protection
against rocks and other debris.

Wiper system and rain sensor.
The front wiper system has two
fixed speeds and an automatic
rain sensor function. Washer fluid
is delivered via two heated jets,
ensuring uniform coverage of the
entire windscreen area.
The rear wiper system is also
designed for maximum visibility
in all conditions. The rear washerjet is located on the roof spoiler,
close to the third brake light.
ParkAssist.
This optional parking aid
(standard on Cayenne Turbo)
uses an acoustic signal and
visual distance displays to warn
of obstacles at the front or rear.
A total of 12 sensors are neatly
concealed in the front and rear
aprons.
The front and rear LED displays
are located on the dashboard
and rear rooflining, respectively.
An intermittent warning tone
increases in rapidity as the
obstacle is approached.
Reversing camera.
The optional reversing camera
provides high-resolution, high-
contrast colour pictures. The
system is particularly useful
during parking manoeuvres or
when preparing to fit a trailer.
After use, the camera is automat-
ically retracted to protect the lens.
