PORSCHE CAYNNE 2010 1.G Information Manual

PSM has three additional func­
tions that help reduce braking
distances. If the throt tle pedal
is released suddenly, PSM

automatically readies the braking
system. The pressure in the
brake lines is marginally increased,
bringing each of the pads into
light contact with the correspond ­
ing disc. If the driver goes on
to apply the brakes, the calipers
respond more quickly and the
braking distance is reduced. In an emergency stop – i.e. when
the pressure on the brake pedal
exceeds a certain threshold –
the brake assist function uses the
PSM hydraulics to apply maximum
braking force at all four wheels.
For added safet y, the system
also readies the brakes whenever
a decreasing distance to the
vehicle in front is detected. The
optional adaptive cruise control
and PSM interact to prefill the
brakes.
Even if adaptive cruise control is
inactive, the system registers the
speed of the vehicle in front and
automatically readies the braking
system. In addition, the system
alerts the driver to the decreasing distance by briefly tugging on
the brakes.
PSM also features a trailer
stabilisation function – for a
significant contribution to car
and trailer safet y.
Within the laws of physics, it
compensates for load transfer
caused by throt tle and brake

inputs up to the maximum degree
of lateral acceleration. It also en ­
hances the car’s driving dynamics
and directional stabilit y when
accelerating on inconsistent road
surfaces.
Other features include a special
control strategy in the ABS
for braking on loose surfaces.
By briefly locking the wheels, a wedge is formed ahead of each
t yre which provides additional
purchase to help slow the car,
e.g. on gravel or snow.
For a more involving driving

experience, PSM can also be
disabled, but remains active in
the background.
Standard on all new Cayenne
models.

ration of the car. Using
this information, it is possible to
calculate the actual direction of
travel at any given moment. If
the car begins to oversteer or
understeer, PSM applies selective
braking on individual wheels to
restore stabilit y. If necessar y,
PSM can also intervene in the
engine management system to
temporarily modif y the amount of
drive transmit ted to the wheels.
Porsche Stability Management
(PSM).
Porsche Stabilit y Management
(PSM) is an electronic control
system that uses a range of
functions – including anti ­lock
braking (ABS) – to help stabilise
the vehicle (and trailer, if fit ted)
in hazardous road scenarios.
Throughout each journey, sensors
monitor the direction, speed,

curtain­t ype airbags on each
side of the roof offering opti ­
mum head protection for both
rows of seats and side impact
protection elements in each
door. Side airbags at the rear
are also available as an option.
Two impact sensors are located
at the front of the car to enable
bet ter detection of a head­on
collision. The driver and front
passenger airbags use a gas
generant based on an organic
propellant. As a result, the air ­
bags are lighter, more compact
and easier to recycle. A roll ­over
detection system provides
additional protection in the event
that the car were to overturn.
Using sensor ­acquired data, it
enables early deployment of
the curtain airbags and triggers
the seat ­belt pre ­tensioners.
Seat belt system.
The Cayenne models feature
three ­point seat belts on all
five seats, as well as seat ­belt
pre ­tensioners (front and outer
rear seats) and force limiters
(front seats only).
ISOFIX mounting points.
The front passenger seat and
outer rear seats are equipped
with ISOFIX mounting points for
compatible child seats (p. 84)
as standard. If a child seat is
mounted on the front passenger
seat, the corresponding airbag
can be quickly deactivated using
a key ­operated switch.
Airbags.
All Cayenne models are equipped
with full ­size front airbags for
driver and front passenger as
standard. These are augmented
by Porsche Side Impact Protec ­
tion (POSIP). This comprises
a side airbag in each front seat,
Bodyshell construction.
Our ongoing development of
the light weight steel body is a
decisive factor in the enhanced
passive safet y and unparalleled
rigidit y of the Cayenne body.
In the event of an accident, a
system of side and cross ­

members at the front of the car
helps to channel impact energy
in a safe and predetermined
manner. The interior is protected
by hot ­formed super high ­strength
steel reinforcements, including
side intrusion beams in each of
the doors.

Weight reduction is a key aspect
of our design philosophy derived
from our rich racing heritage.
Part of our R&D Centre, the
Motorsport Department is locat ­
ed in Weissach where it shares
premises with the Automotive Industry Exhaust Emission Centre
(ADA).
Just a coincidence? We call
it symbiosis.
In practice: the new Cayenne is
up to 185 kg lighter, depending
on the model.
1) This was achieved
through new weight ­saving devel ­
opments and materials, new pro ­
duction technologies, advanced
functionalities and concept
modifications. By using lighter materials, for example, we have
halved the weight of the tailgate.
New materials are also a feature
of the axle construction, with
steel being replaced where pos­
sible by light weight alter
natives
such as aluminium and plastic.
The benefits for the driver:
greater agilit y and driving
dynamics – with lower fuel
consumption. Ef ficiency at
its best.
This is achieved using advanced
engine concepts featuring tech ­
nologies such as DFI (p. 38),
VarioCam Plus (p. 37), the auto
start /stop function (p. 36), the
parallel full hybrid drive and con ­
sistent light weight construction.The concept behind every car we
build is based around the pursuit
of performance. This has been
the case since 1948. Another
of our traditional core values
is efficiency. At Porsche, we

are continually striving to find a
successful balance bet ween
the t wo.
Great achievements are something to be proud of.
Even more so if they benefit the world around you.

has a separate control system
which the engine management
system uses to establish the
optimum amount of fuel – for
effective emissions control.
The exhaust­gas recirculation on
the Cayenne Diesel routes part
of the exhaust gas back into the
combustion process, resulting
in lower peak combustion tempera ­
ture
and therefore lower nitrogen
oxide emissions. An oxidation
catalyst also forms an integral part of the process along with

a diesel particulate filter. This
ensures that the new Cayenne
Diesel meets the EU5 emissions
standard.
Fuel and fuel economy.
Increasing performance while
enhancing fuel economy. The
new Cayenne comes in a choice
of three dif ferent drive systems
each featuring state ­of ­the ­art
technology for high ef ficiency and
relatively low fuel consumption.
The petrol ­engined models
already operate on fuels with an
ethanol content of up to 10%. The diesel engine is compatible
with a biodiesel blend of max. 7%.
This further improves the carbon
dioxide balance since the plants
grown for the production of
biofuels absorb carbon dioxide
from the atmosphere. As you
can see, for the benefit of the
environment, we are continually
working on making our cars more
ef ficient – as well as compatible
with alternative fuels. While
ensuring that they remain one
thing: a thoroughbred Porsche.
Fuel system.
We have also applied the highest
standards in order to protect
the environment from fuel
evaporation. The non ­return

fuel supply system provides a
considerable reduction in vapour
emissions. The lines carrying
vapour are made from multi ­layer
plastics. A large active ­carbon
filter and multi ­layer plastic fuel
tank help reduce evaporation still

advanced drive concepts –
from petrol and diesel engines to
our new parallel full hybrid drive.
This is further aided by the rapid
warm ­up cycle of the cataly tic
converters. The optimum operat ­
ing temperature is reached earlier
so emissions are reduced sooner
when starting from cold.
On the petrol ­engined and hybrid
models, another important feature
is the use of t win oxygen ­sensor
circuits. Each bank of cylinders Exhaust emissions.
The new Cayenne models are
all equipped with the latest emis ­
sions technology. As a result,
they comply with the stringent
European exhaust emissions
standard, EU5.
Whatever the class, every Porsche
combines high performance
with comparatively moderate
emissions. On the Cayenne
models, this is achieved using
Porsche engines.
Performing for today – and the future.

Thanks to single­spark coils on
each of the cylinders, the entire
ignition system on the petrol ­
engined models, with the
exception of the spark plugs,
is maintenance ­free.
These modest service require ­
ments mean less waste disposal
and fewer demands on natural
resources. They also lower the
cost of ownership while keeping
your car on the road. The new Cayenne S Hybrid
doesn’t require any additional
servicing.
Service intervals for the Cayenne
models are dependent on a range
of factors, including local fuel
qualit y. For full details of service
intervals in your country, please
consult the relevant price list
or contact your Porsche Centre.
Materials and recycling.
Owning a Porsche should be a
lasting pleasure with minimal
impact on the environment. This
Porsche principle can be summed
up in one word: sustainabilit y.
The light weight exhaust on the
Cayenne models, for example,

is constructed from long ­life
stainless steel.
Every Porsche model is entirely
free of asbestos, CFCs and
components manufactured using
CFCs. All legal requirements in
respect of recycling are fulfilled.
Materials are clearly labelled for subsequent identification and
sorting to facilitate ef ficient
recycling.
While more than 95
% of the car
can be recycled using current
technologies, the chances are
your new Cayenne may never
need recycling at all. After all,
t wo thirds of all the cars we have
ever made are still on the road
t o day.

Servicing.
With lengthy service intervals
and long ­life components, vehicle
maintenance is kept to a min­
imum. In the case of the oil filter,
for example, all that ’s replaced
is an easily recyclable paper
element. The oil filter casing
remains on the car.
All moving parts inside the engine
are fully self ­adjusting. The valve
clearances, for instance, feature
automatic hydraulic control.
Noise.
As paradoxical as it may seem,
the distinctive Porsche sound is
also created by what you don’t
hear – the absence of unwanted
noise. Naturally, its main origin is
deep within the engine. But that ’s
not all. Our holistic approach
to vehicle design also extends
to the acoustics. Which is why
we’ve optimised them for the
entire car.
To minimise ‘play’ bet ween com ­
ponents, we’ve used stronger,
lighter and more temperature ­
resistant materials. This reduces
mechanical noise. Large ­volume
silencers and air intake manifolds
also help to eliminate noise –
throughout the life of the car.
Tyre noise has been drastically
reduced in collaboration with
our of ficial t yre partners. Wind
noise levels have also been
lowered thanks to aerodynamic
refinements.
All that remains is a sound that is
pure Porsche.
