oil PORSCHE CAYNNE 2010 1.G Information Manual

The front wheel arches are
extremely well defined, while
the ‘power­domed’ engine lid
further underlines the sheer
power and resolution within –
this is particularly dominant
on the Cayenne Turbo. Other
distinguishing features include
the visibly drawn ­in flanks. The sharper profile exudes
eagerness and determination,
which is further emphasised by
the dynamic rear roof pillars
and flowing coupé
­like silhouet te.
The rear wheel arches are t ypical
of a sportscar, streamlined and
muscular, while the contoured
roof spoiler pays homage to the
Carrera GT. Further proof of how
harmoniously our performance
concept has been integrated into
our design philosophy – across
the entire model range. The tapered rear screen and
streamlined rear section underline
the flared wheel arches – for a
t ypically distinctive rear view.
The exterior is unmistakably
Porsche. The inside too. But not in
the way you are used to perhaps.
The desire to achieve greater
agilit y, flexibilit y and everyday
practicalit y has led to a complete
revision of the interior (p. 78
onwards): clearly inspired by the
Carrera GT, the centre console
now rises to meet the dashboard
– for an even more involving
drive.
The rear cabin area is larger and
more variable than before. It
features split ­folding seats with
fore/aft adjustment and adjust ­
able backrest angle – for extra
legroom and greater comfort.
In addition, a wide range of
new materials has been used.
Practically every thing has been
changed. But one thing remains
the same: the focus on you and
your passengers.
The contours of the front section
draw the eye, reflecting the car’s
excellent dynamics at first glance.
The elongated engine lid is clearly
reminiscent of Porsche racecars
from the 1960s.
When you look at someone’s face,
you see much more than their
external features. We are proud to
say, it ’s the same with the new
Cayenne models. In fact, what you
see is more sports performance
than ever before.
Children can give you a great deal of joy.
Even more so when they’ve inherited your finest characteristics.

consistently within a specific
temperature range. The engines
in the new Cayenne models are
therefore designed for optimum
cooling.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20% of coolant flows longi­
tudinally through the crankcase,
the remaining 80% serves the
cylinder heads using the proven
cross ­flow principle (from hot to
cold).
On all Cayenne models, the piston
heads are cooled using oil ­spray
jets integrated within the main
lubrication system. In addition,
thermal management ensures
that the optimum operating tem ­
perature for the engines is
reached more quickly. This keeps emissions and fuel consumption
low, even when starting from cold.
The entire cooling system is
designed for prolonged heav y
­

dut y use, e.g. of f ­road driving
or heav y towing and carrying
applications.
Lubrication.
The V8 engines use dry ­sump
lubrication to ensure a consistent
supply of oil in all load conditions,
especially in of f ­road terrain.
The oil reservoir is located inside
the engine. This saves on space
and reduces weight.
Oil is circulated around the V8
engines using a demand ­driven
pump. This has been designed for the toughest driving scenarios
on and off road, including per­
formance driving and extreme
gradients.
The V6 engine in the Cayenne has
a wet ­sump lubrication system.
Ensuring a reliable supply of oil,
no mat ter how challenging the
driving conditions.
Direct fuel injection on the
diesel engine (common-rail
injection system).
On the Cayenne Diesel, direct
fuel injection comes courtesy of
a common ­rail injection system.
The injection pressure of up
to 1,800 bar ensures optimum
distribution of the air/fuel mixture
– for greater performance. The
piezoelectric injection valves
provide flexible injection rate

adjustment, using exactly metered
quantities of fuel, with multiple
injections for each power stroke
to deliver smooth combustion.
Cooling systems.
A high ­performance engine can
only maintain its maximum
capabilit y over a long service life
if all components are operating
Direct fuel injection (DFI).
DFI injects fuel directly into the
combustion chamber at up to

120 bar with millisecond precision
using electromagnetic injectors.
The injector position and spray
geometry have been carefully
designed to improve output,
torque, fuel economy and emis ­
sions. The swirling of the fuel as
it enters each chamber increases
the mixing of air and fuel, thereby
enhancing combustion. By form ­
ing the air/fuel mixture directly
in the combustion chamber, DFI
contributes to engine cooling.
As a result, it was possible to in ­
crease the compression ratio and
therefore power and efficiency.

Compression with precision.
Essential for getting right to the point.

Standard on all new Cayenne
models.
Halogen headlights.
The projector­beam halogen
headlights feature automatic
static range control and reflection
high ­beam lights – for optimum
illumination of the road.
Standard on the new Cayenne,
new Cayenne Diesel, new
Cayenne S and new Cayenne S
Hybrid.
Bi-Xenon main headlights with
Porsche Dynamic Light System
(PDLS).
Featuring halogen auxiliary
headlights, integrated headlight
cleaning and automatic dynamic
range control, the Bi ­Xenon
headlights provide more uniform
illumination of the road in both
dipped and high ­beam mode.
The dynamic cornering light
function swivels the headlights
towards the inside of a bend
based on the current steering
angle and road speed. The static
cornering lights activate the
auxiliary headlights in order to illuminate more of the road in
tight bends and turns.
PDLS also features speed
­
sensitive headlight control and
an adverse weather function,

which is activated in conjunction
with the rear foglight – for even
greater safet y, not just at night
and during cornering.
Standard on the new Cayenne
Turbo. Optional for all other
new Cayenne models.
Daytime running lights.
Fit ted as standard on all new
Cayenne models: LED day time
running lights. On the new
Cayenne, Cayenne Diesel,
Cayenne S and Cayenne S
Hybrid, these are arranged hori ­
zontally in the front light units, whereas on the Cayenne Turbo
each headlight unit has four

LED spotlights. Day time running
lights improve safet y in the
day time as they make you more
visible to other road users.
Taillights.
LED technology is used for
all functions on the new rear
light modules. For an ultra ­fast
response and greater luminance.
In short: for greater safet y.
In an emergency stop, the
adaptive LED brake lights on
the new Cayenne models pulsate
to alert the traf fic behind more
quickly to a critical situation.
The high ­level third brake light is
integrated into the roof spoiler.
Automatic headlight activation.
The headlights are automatically
switched on when darkness sets
in or when driving through a tun ­
nel in the day time. Other features
include an automatic switch ­of f
and ‘Welcome Home’ function –
when you arrive at a destination
after dark, the headlights remain
illuminated for a user ­defined
period, lighting your path from
the car.
It ’s always a pleasure taking
corners in a Porsche. Especially
when they’re now so visible
at night. The striking lighting
arrangement is also instantly
recog
nisable. The lights on the
new Cayenne Turbo feature a
unique design that differs signifi ­
cantly from all other models.
Driving with foresight.
Quite literally.

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.

with PCM including navigation
module, map data from the navi ­
gation system. It also shows the
set tings of the optional adaptive
cruise control or gives various
warnings, such as alerts from Tyre
Pressure Monitoring (TPM), which
is also available as an option. On the new Cayenne S Hybrid, the
display also provides information
about the energy management.
Oil pressure, oil and coolant
temperature as well as the fuel
level are displayed using analogue
gauges, while the boost pressure
gauge on the new Cayenne Turbo
is digital. A compass display in
the instrument cluster is available
as an option in conjunction with
PCM. This shows the four cardinal
and four ordinal directions with
degree increments as well as your
current altitude.
The steering column offers man­
ual height and reach adjustment
