Porsche braking systems are
renowned worldwide as the
benchmark in performance and
stability. The Cayenne models
continue this tradition, offering
excellent deceleration – even

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

All brake pads are fitted with
individual wear sensors. When new

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.
