2011 PORSCHE CAYENNE ABS

Available on the Cayenne,
Cayenne Diesel, Cayenne S
and Cayenne Turbo, this function
readies the car for of f-road use
or reverts the set ting to normal
road driving.
In Of f-road Mode 1, for example,
the maps for all relevant
systems, e.g. ABS, are adapted
to provide optimum traction. In addition, High Level I is
selected on vehicles featuring air
suspension with PASM. If that ’s
not enough, the air suspension
can be raised further to High
Level II to increase the approach/
departure angle and wading depth.
Push the of f-road control forward
again on the Cayenne, Cayenne S
and Cayenne Turbo to activate
Off-road Mode 2 – for even great-
er traction on dif ficult terrain,
the multi-plate clutch can be fully
locked.
The electronically variable rear
differential on the optional
Porsche Torque Vectoring Plus
(PT V Plus) is integrated within
the all-wheel drive system. This
automatically ensures the opti-
mum distribution of drive torque on particularly uneven surfaces.
If one of the rear wheels begins
to slip, the rear dif ferential varies
the amount of torque transmit ted
through each drive shaf t, thereby
restoring traction. In Of f-road
Mode 3, the rear dif ferential can
be manually locked using the main
of f-road control. Then both rear
wheels receive the same amount
of torque, regardless of surface
conditions. The optional PDCC
(p. 53) enables greater wheel
articulation in all three modes,
improving traction still further.
For effective prevention of dam-
age to the underside of the car,
all Cayenne models can be
equipped with optional of f-road
underbody protection comprising
rock rails with integrated skid
plates, a reinforced engine-bay
guard, additional protection
for fuel tank and rear axle, and
a second towing lug.
Operating concept.
With the help of Porsche Traction
Management (PTM), the Cayenne
can cope with even the most
demanding of f-road scenarios.
Simply move the main of f-road
control on the centre console
forward or backward to select
one of up to three off-road
modes (depending on the model).
Steep ascents leading to snow-
covered mountain lodges, boggy
ground or muddy, loose surfaces
– all situations that the Cayenne
handles superbly with intelligent
all-wheel drive. The drive systems
featured on the Cayenne models
deliver exceptional torque. For
plent y of power on tap. On any
terrain.
From urban jungle to the windy wilds.
The Cayenne is perfectly at home on any terrain.

Main of f- road control

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 Cayenne
models.
accele 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,

has a separate control system
which the engine management
system uses to establish the
optimum amount of fuel – for
effective emissions control.
The exhaust-gas 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 Cayenne Diesel
meets the EU5 emissions

Fuel and fuel economy.
Increasing performance while
enhancing fuel economy. The
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 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 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 single-spark 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 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 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 today.

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.
