& WARNING
Rearward-facing child restraints:
• A child in a rearward-facing child safety seat installed on the
front passenger seat will be seriously injured and can be killed if
the front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious or even fatal injury to the child.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
• If the PASSENGER AIR BAG OFF light does not come on and stay
on, immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer. •
Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To
activate the convertible locking retractor:
-Place the child restraint on a seat, preferably on the rear
seat.
-Slowly pull the belt all the way out.
-Route it around or through the child restraint belt path
=>& .
-Push the child safety seat down with your full weight to
get the safety belt really tight.
-Insert the belt tongue into the buckle for that seating
position.
-Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
-You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated.
-Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
-Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.

& W ARNING (continued )
• Improper use of child restraint anchors (tether anchors ) could
lead to injury in a collision . The anchors are des igned to withstand
only those loads imposed by correctly fitted child restraints .
• Never mount t wo child restraint systems on one LATCH lower
anchor point .
• Never attach two ch ild restraint systems to one tether strap or
tether anchorage .
• Always follow the instructions provided by the manufacturer of
the child re straint you intend to install in your Audi.
• Never use child restraint tether anchorages to secure safety
belts or other kinds of occupant restraints.
• Never attach a tether strap to a tie-down hook in the luggage
compartment.
• Never secure or attach any luggage or other items to the LATCH
lower anchorages or to the tether anchors.
• If a tether or other strap is used to attach a child restraint to the
front passenger seat , make sure that it is not so tight , that it
causes the weight-sensing mat to measure more weight than is
actually on the seat.
• The heavier weight registered can make the system work as
though an adult were on the seat and deploy the Advan ced Airbag
when it must be suppressed causing serious or even fatal injury to
the child .•

Intelligent technology
Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders" .
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle
systems such as, for example, engine function, emission control, as
we ll
as for the airbags and safety belts.
These electronic control modules also record vehicle-related data
during normal vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, d irection,
braking as well as restraint system use and performance in the
event of a crash or other condition . Stored data can only be read and
down loaded with special equipment. •
Electronic Stabilization Program (ESP)
General information
The ESP improves the vehicle stability.

sw itch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especial ly when
acce lerating and cornering. ESP reduces the risk of skidding and
improves stability under al l road conditions.
The system operates across the entire speed range in combination
with the ABS system . If the Anti-Lock Brake System (ABS) malfunc ­
t ions, the ESP will a lso shu t down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regu lation System (ASR) are integrated in the e lec ­
tronic stabilization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors. The rotational

Ap plies to vehic les: w it h n atu ral lea ther
Natural leather
Audi makes grea t efforts t o main tain the pro perties,
n at ural look and feel of in terior le ather.
Gener al
We offer many d ifferent types of leather on our vehic les. Most are
different types o f nappa leather, which has a smooth surface and
comes in various co lors.
T he in tensity of the color determi nes the vis ual c h aracteristics and
appearance . If the surface of the leather has a typical natura l look ,
t hen t he leat her is a nap pa lea ther that has been left in a re lati vely
natural condition. Th is leather offers part icu lar ly good comfort and
breathes wel l. Fine veins, closed grains, insect bites, skin folds, and
subt le variations in color remain visible. These characteristics
demonstrate that the material is genuinely natural.
Na tura l nappa leather is n ot covered by a color fi nish . It is there fore
more sensitive to soiling a wear, which is something you need to
co nsider if chi ldren, a nimals or other factors m igh t prove to be
particularly hard on the leather.
By contrast, leather types that are covered by a colored finish layer
are more durable. Th is has a posit ive effect on the leather's resis­
tance to wear and soiling in daily use. On the other hand, the typical
character istics o f natura l leather are barely or not appare nt.
However, this does not mean that the leather itself is of inferior
qual ity.
Care and handling
Because of the exclusive nature of t he types o f leather tha t Audi
uses and their unique properties (such as sensit ivity to oi ls, grease, .,_
