---------..!...--------------------------------------
0 Note
On vehicles with power individual rear seats* some criteria must be
observed when attaching the child restraint using the
LATCH
system :
• To attach the child restraint securely, the seat must be moved to
the farthest rear position, the seat height set to the lowest position
and the head restraint must be adjusted to the ver tical position
~ page 97.
• If a child safety seat is attached to one of the rear seats, this seat
must not be adjusted using the power controls under any circum­
stances. The easy entry function for this seat must also be deacti ­
vated in the
MMI ~ page 700. The child safety seat as well as the
rear seat can be damaged by the adjustment process .•

securely engaged the lower anchorage.
- Tighten the strap following the child restraint manufac­
turer's instructions.
Releasing
- Loosen the tension on the strap following the child
restraint manufacturer's instructions .
- Depress the spring catch on the hook. -
Hold the spring catch in depressed position.
- Move the hook in the direction of the vehicle floor so that
there is enough space to release the anchorage hook
from the lower anchorage.
& WARNING
• Improper installation of child restraints will increase the risk of
injuries in a crash.
• Always refer to the child restraints manufacturer's instructions
for proper installation of the child restraint and proper use of the
lower anchorages or safety belts
in your vehicle. •
Tether anchors

backs
Beginning wi th model year 2000 , the rear seating positions are
equipped with three tether anchors .
The tether anchors for the three rear seating positions are located
in recesses in the rear window shelf~ fig. 253 . Vehicles with power
individual rear seats* are equipped with two tether anchors. .,.

& WARNING
Improper installation of child restraints will increa se the r is k of
injury and death in a crash .
• Improper use of child restraint anchors (tether anchors) could
lead to injury in a colli sion. The anchor s are designed to withstand
only tho se load s impo sed by correctly fitted child restraints .
• Never mount two child restraint systems on one LATCH lower
anchor point .
• Never attach two child restraint sy stems to one tether strap or
tether anchorage .
• Always follow the instructions provided by the manufacturer of
the child restraint you intend to install in your Audi .
• Never use child restraint tether anchorages to secure safety
belts or other kinds of occupant restraint s.
• Never atta ch 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
c auses 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 Advanced Airbag
when it must be suppressed causing serious or even fatal injury to
the child. •

Tether strap
A tethe r is a straight or V-sh aped s trap t hat at taches the
top part of a chil d re str aint to s peci al anc ho ra ge poin ts in

The p urpose of the tether is to reduce the forward movement of the
c hi ld r estraint in a crash, in orde r to he lp redu ce th e risk o f head
injury that could be caused by striking the vehicle interior.
F o rw ard facing c hild res train ts manufact ure d after Sep te mb er 1,
1999, are required by U.S . federal re gulations to comply with child
head m ovement performance requ iremen ts . These new pe rfo r­
mance requirements make a tether necessary on most new child
safety seats .
& WARNING
Improper installation of child restraints will increase the risk of
injury in a crash .
• Never attach a child safety seat 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 .

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 Advanced Airbag
when it must be suppressed causing serious or even fatal injury to
the child .•
Using tethers on rear-facing child restraint
systems
Currently, few rear -facing child restraint systems come with a tether.
Please read and heed the child rest raint sy stem manufactu rer's
instruct ions ca reful ly to determine how to properly insta ll the
tether .
& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be ser iously 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 , or door .
• A tight tether or other 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 caus ing serious
or even fatal injury to the child .
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF l ight does not come on and stay on,
& WARNING (continued)
immediately install the rear-facing child safety seat in a rear
seating po sition and have the airbag system inspected by your
Audi dealer . •

Notice about data recorded by
vehicle control modu les
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 retrieva l 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
well as for the airbags and safety belts.
These electronic control modules also record vehicle-related data during norma l vehicle operation for diagnost ic 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 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 .•
Electron ic Stabilizat ion Program (ESP)
General =nformation
The ESP improves the vehicle stability.

co nso le w it h ES P
swi tch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especia lly when
accelerating and cornering. ESP reduces the risk of skidding and
improves stabil ity under all road conditions .
T he system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP wil l also shut down .
How th e sys te m w ork s
The Anti -Lock Brake System (ABS) , Electronic Differential Lock (EDU
and the Anti-Slip Regulation System (ASR) are integrated in the e lec­
tronic stabi lization 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
speed of the vehic le about its vertical axis, the lateral acce leration
acting on the vehicle, the brake pressure and the steering angle are
a ll measured .
