-Child Safety ------ ~---------------------------------
& WARNING (cont inued)
• It is safer to install a forward-facing child safety seat on the
rear seat.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 231. Special precau­
tions apply when installing a child safety seat on the front
passenger seat=>
page 208, "Child restraints on the front seat -
some important things to know".
& WARNING
Always take special precautions if you must install a forward or rearward-facing child restraint on the front passenger's seat in
exceptional situations:
• Whenever a forward or rearward-facing child restraint is installed on the front passenger seat, the PASSENGER AIR BAG
OFF light must come on and stay on whenever the ignition is
switched on .
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, perform the checks described=>
page 217, "Monitoring
the Advanced Airbag System".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on.
• Improper installation of child restraints can reduce their effec­
tiveness or even prevent them from providing any protection .
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child.
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.
• Never place additional items on the seat that can increase the
total weight registered by the weight-sensing mat and can cause
injury in a crash .
& WARNING
Forward-facing child restraints:
• Always make sure the forward -facing seat ha s been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up, against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position .
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& 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 armrest, 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.

& WARNING (continued)
• 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 acti­
vate 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.
Controls and equip­
ment Safety first Vehicle operation
-
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 lock ing
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.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a crash.
• Always make sure the seat backrest to which the child restraint
is installed is in an upright position and securely latched into place
and cannot fold forward. Otherwise, the seat back with the child
safety seat attached to it could fly forward in the event of an acci­
dent or other emergency situation.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used
=> page 231. Special precau­
tions apply when installing a child safety seat on the front passenger seat =>
page 208, "Child restraints on the front seat -

Safety first Vehicle OP-eration
Child Safety
Forward fac ing ch ild restraints manufactured after September 1,
1 999, are required by U.S. feder al regul ations to comp ly wi th new
child head moveme nt pe rformance requ ireme nts . These new per for­
mance re quirements ma ke a tether necessary on most new child
safety seats.
& WARNING
Improper installation of child restra ints will increase the risk of
injury and death in a crash.
• Always follow the instructions provided by the manufacturer
of the child restraint you intend to install in your Audi.
• Improper use of child restraint anchors (including tether
an chor s) can lead to injury in a collision . The anchors are designed
to withstand only those loads imposed by cor rectly fitted child
restraints.
• Never mount two child restraint systems on one LATCH lower
an chor point .
• Never attach two child restraint systems to one tether strap or
tether anchorage .
• Never attach a tether strap to a tie-down hook
in the luggage
c ompartment.
• Never use child restraint tether anchorages to secure safety
belts or other kinds of occupant restraints .
• Never se cure or atta ch 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 Advanced Airbag
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 .

0 Note
If you leave the child restraint with the tether strap firmly installed
for several days, this could leave a mark on the upholstery on the seat
cushion and backrest in the area where the tether strap was installed.
The upholstery would also be permanently stretched around the
tether strap. This applies especially to leather seats.•
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems come with a tether.
Please read and heed the child restraint system manufacturer's
instructions carefully to determine how to properly install the tether.
& WARNING
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 armrest, or door.

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 retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed 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 w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally 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 vehicle speed, direction, 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.

ESP is des igned to help you maintain vehicle control in s ituations
where the car approaches the limits of "grip", especia lly when accel­
erat ing and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilizatio n pro gram. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­
ment data provided by high performance sensors. The rotational
speed of the vehicle about its vertical axis, the lateral acceleration ...

time the battery is charged =>
page 303.
Have the batte ry checked when you take your vehicle in for serv ice .
You are well advised to rep lace a battery that is older than 5 years.
With certa in types of a irbag deployment, the ba ttery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 220.
Di sconne cting th e bat tery t ermina ls
Some vehicle f unct ions (power window regulators, fo r example) are
lost if the battery termina ls are disconnected . These functions have
to be re learned after the battery termina ls are connected aga in. To
prevent this, t he battery should only be disconnected from the
vehicle e lectr ica l system when absol ute ly necessary for repairs.
Vehicles not driven for long periods
If you do no t dr ive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. Th is
red uces e nergy consumption and main tains sta rt ing capabili ty ove r a
longer period=>
page 258.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key*, the remote
control or the power seat adjustment. The convenience functions will
be availab le aga in whe n you tur n on th e ignition and start the eng ine.
Winter operation
Dur ing the winter months, battery capac ity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear w indow defogger, etc., a re
used more often.
Avoid unnecessa ry power consum ption, part ic ula rly i n city traffic o r
when traveling only short distances. Let your authorized Audi dealer check the capacity of the vehicle battery before w inter sets in
=>
page 303 . A well charged battery will not only prevent start ing
prob lems when the wea ther is cold, but will also las t longe r.
Vehicle OP-eration
(I) Tips
If your vehicle is left standing fo r seve ral weeks at extremely low
temperatures, the vehicle battery should be removed and stored
w here it will not free ze. This will preven t it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the
battery.
