light PORSCHE 911 TURBO 2004 4.G Information Manual

Complementing the front airbags
is the latest generation of Porsche
Side Impact Protection (POSIP).
This comprehensive package
includes two additional airbags for
each front seat: a thorax airbag
in the side of each backrest,
and a head airbag located in each
door. Each side airbag has anapproximate volume of 8 litres,
ensuring maximum protection
over the entire seat adjustment
range. Also incorporated within
the POSIP package are side-
impact protection beams in the
doors.Other standard features include
integral head restraints, an
energy-absorbing steering column,
height-adjustable three-point seat
belts with pre-tensioners and
force limiters, energy-absorbing
structures in the dashboard area
and flame-retardant materials
throughout the interior. The new 911 Turbo has a unique
passive protection system
featuring six separate airbags.
The full-size front airbags for
driver and front passenger have
a two-stage inflation capability.
With this technology, the
deployment of each airbag is
dependent on the force and
nature of the accident (e.g.,
frontal or diagonal impact). In
a low-speed crash, the airbag
is only partially inflated, thereby
minimising discomfort to the
occupants.
The airbag control unit is located
in the centre tunnel where it
receives additional information
from a pair of impact sensors near
the headlights. This arrangement
enables faster and more accurate
evaluation of impact forces in the
event of a crash.

Passive safety: airbags.
Added side protection with intelligent deployment.

Porsche Communication
Management (PCM). This
comprehensive system features
satellite navigation with a
separate DVD drive in the
luggage compartment for
the single navigation disc.
The one-touch switches on the
centre console are logically
positioned for optimum ease of
use. All instruments are perfectly
placed within the driver’s field of
vision. The air-conditioning system
is fully automatic and features a
highly effective active carbon filter.
This added convenience gives
you greater freedom to enjoy the
driving experience.
The tinted front glass and generous
rear screen offer excellent fore-
and-aft visibility. The front side
windows have a water-repellent
finish, which automatically
disperses moisture and dirt.
The result: optimum visibility in
poor weather conditions.
Instruments.
The classic arrangement of five
round instruments provides a
clear overview of all key information.
The digital display in the centre-left
dial (speedometer) provides main
and trip odometer readings. The
central rev counter, featuring the
‘turbo’ logo, includes the standard
on-board computer display.
This multi-purpose field contains a
permanent digital speedometer
as well as the following optional
information: boost pressure,
average speed, average fuel
consumption, tyre pressure,
current radio station, navigation
instructions and remaining range
till empty. When ‘Sport’ mode
is selected on the optional Sport
Chrono Package Turbo, the
temporary increase in torque is
clearly indicated using an arrow
symbol in the boost pressure
display. The third display, in the
centre-right dial, contains a
clock and external temperature.
The dot-matrix technology used in
each of these displays provides
a high resolution for icons and
text. Design and legibility are
further enhanced with brilliant
white backlight illumination.

Comfort
Interior.
For the pure enjoyment of performance.
The passenger compartment in the
new 911 Turbo is another example
of uncompromising design. As you
would expect, it offers the highest
standards of ergonomics, comfort
and quality. The seats, dashboard,
doors and rear side panels are
finished in leather as standard. Atthe centre of the cockpit is a new
gear lever design that’s exclusive
to the new 911 Turbo.
Other standard features include
a three-spoke sports steering
wheel offering 40 mm of
adjustment for both height and
reach. A three-spoke multi-function
steering wheel – available as
optional equipment – provides
direct access to audio, navigation
and (if fitted) telephone functions.
The standard audio package
is the latest evolution of

Storage compartments.
The new 911 Turbo is not only
a powerful performer, it is also
highly versatile. Added to the
comfort and ergonomics of the
interior are a range of practical
features.
The storage compartments in the
doors and centre console feature
matching upholstered lids. These
are positioned at precisely the
same height to form comfortable
armrests on longer journeys.
Beneath the front passenger
airbag, behind a fold-down trim,
are two cupholders for driver and
front passenger. Beneath the
cupholders is a lockable glove
compartment featuring integral
CD storage.
Two 12 V sockets (including the
cigar lighter) provide power for
electrical equipment. An optional
fire extinguisher is also available,
installing neatly out of sight but
always within reach directly ahead
of the driver’s seat.
‘Welcome Home’ lighting.
This standard function provides
generous illumination via the
foglight units when the key remote
is used to lock or unlock the
car. As the name suggests, it is
particularly convenient when
returning home after dark. On
vehicles equipped with the optional
Sport Chrono Package Turbo, the
timing delay can be programmed
via the Porsche Communication
Management (PCM) terminal.
ParkAssist.
This optional parking aid is auto-
matically enabled whenever you
select reverse gear. Move too
close to a stationary object and
a warning signal is emitted.
Continue to reverse and the tone
increases in frequency. The
ultrasonic sensors are neatly
concealed within the rear apron
moulding.
Cruise control.
This optional system is available
from 30 to 240 km / h
(20 – 149 mph) and can even be
used in first gear. The system is
operated using a separate control
stalk on the steering column.
HomeLink®.
This optional garage-door opener
is integral to the car and offers
full remote control for up to three
garage doors. It can also be used
with gate, home lighting and alarm
systems. Compatible with virtually
all garage and gate systems.
Rear wiper.
Also available as an option, the
rear wiper system includes a flat
and streamlined ‘aero’ blade which
blends with the exterior of the car.
Interior and exterior mirrors.
All three rear-view mirrors on the
new 911 Turbo feature auto-
dimming glass as standard. The
interior mirror also includes an
integral rain sensor for the front
wiper system.
Slide /tilt sunroof.
This electrically operated and
steplessly adjustable slide/tilt
sunroof is also available as an
option. In the tilted position,
it offers comfortable ventilation
of the passenger compartment,
even when travelling at high speed.

Luggage compartment.
In addition to the loadspace in the
rear seat area, the new 911 Turbo
has a 105-litre front luggage
compartment. The bulkhead
panelling conceals the standard
audio amplifier for the BOSE
®
Surround Sound System, as well
as the DVD drive for the
navigation module. The optional
CD autochanger is installed on the
right-hand side of the compartment
(looking forwards). The entire
compartment is lined with high-
quality, scratch-resistant
materials.
Roof transport system.
The optional roof transport
system is made from lightweight
aluminium, making it extremely
easy to fit. It is also styled to
match the exterior design as well
as the car’s aerodynamics. The
basic load-carrying bars can
be
combined with a range of
attachments from Porsche
Tequipment, including a roof box
and carriers for bikes, snowboards
and skis. Maximum roof load is
75 kg.
Anti-theft protection.
Standard anti-theft equipment
on the new 911 Turbo includes
an engine immobiliser with in-key
transponder. The comprehensive
alarm system features contact-
sensitive exterior protection and
radar-based interior surveillance.
Vehicle tracking system.
Optional protection includes a
factory-fitted preparation enabling
future installation of a vehicle
tracking system from Porsche
Tequipment. In the event of theft,
the system enables remote
tracking of the stolen vehicle
across most European countries.
Also requires special wiring
loom and higher capacity battery.

At Porsche, we’re exploring every
possibility to improve the environ-
mental compatibility of our cars:
modern materials, reduced fuel
consumption, cleaner emissions,
fewer pollutants and better
recyclability. This commitment is a
Porsche tradition that began in
the 1960s. With the latest evolutionof the 911 Turbo, the rewards are
even greater than ever.
Exhaust emission control.
Combine engineering expertise
with a commitment to the
environment and the resulting
benefits are twofold: exceptional
performance and lower emissions.
One of the cleanest sportscars
in the world today, the new
911 Turbo easily complies with
both the stringent Euro 4 standard
in the European Union as well
as LEV II regulations in the United
States.The technologies used to achieve
this compliance include twin
‘lambda’ or oxygen sensors for
each of the two cylinder banks.
One pair of sensors is used to
measure the levels of oxygen in
each of the twin exhaust tracts.
An additional pair of sensors –
again, one in each tract – enablethe engine management system
to monitor the efficiency of the
catalytic converters.*
Recycling.
Lightweight construction, long-
term durability, exceptional
recyclability: just three of the
techniques employed by Porsche
to improve the environmental
compatibility of our cars.
On the new 911 Turbo, we’ve
used weight-saving design and
lightweight materials to achieve
excellent fuel economy.
All materials and manufacturing
processes have been carefully
selected and specifically refined
to reduce any impact on the
environment. A prime example is
the twin exhaust system, which is
made entirely from stainless steel.
All lightweight materials are easily
recyclable, while the variety ofsynthetics has been significantly
reduced. Recycled plastics are
used in every area of the car
where our exacting specifications
allow. To simplify processing, all
materials are labelled for separate
recycling. Approximately 85 % of
today’s 911 Turbo is compatible
with current recycling techniques.
Water-based paints are used
throughout the car, thus reducing
the need for chemical solvents in
both production and subsequent
servicing. Other harmful materials
omitted from the vehicle include
asbestos, CFCs, and components
manufactured using CFCs.
The result is a car in which
environmental protection is an
integral part of the overall design.
· 94 ·· 95 ·The new 911 Turbo |
Environment
* Not in markets with leaded fuel.
The 911 Turbo is dedicated to performance.
Also with respect to the environment.

Servicing.
Longer service intervals are not
only easier on resources, they
also reduce ownership costs. The
new 911 Turbo has very modest
servicing requirements of 18,000
miles or every two years (standard
service) and 36,000 miles or
every four years (major service).
The replacement intervals for
parts and fluids have also been
significantly extended: engine
oil and filter every 18,000 miles,
air filter every 36,000 miles,
spark plugs every 36,000 miles
or four years, and fuel filter every
56,000 miles.
Noise.
The new 911 Turbo complies with
all noise regulations worldwide.
Instead of resorting to engineencapsulation, we’ve eliminated
noise at source: engine com-
ponents are more rigid, moving
parts are lighter, and tolerances
have been reduced to a minimum.
High-efficiency silencers in durable
stainless steel help to minimise
noise throughout the life of the
car. All that remains, both inside
and out, is the famous Porsche
sound.
Fuel system.
Key developments in the fuel
supply system include a further
reduction in the evaporation of
hydrocarbons. This is achieved
through a combination of active
carbon filter and specially coated
fuel tank. All fuel lines are made
from robust aluminium, while
those carrying vapours use multi-
layer plastic.
