overview: installation
of the seat using the
vehicle's safety belt
system
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
feature on the safety belt to prevent the child safety seat
from moving ==>
page 177 or install the seat using the
LATCH attachments.
- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm)
==> page 177.
If the child safety seat is equipped with a tether strap,
attach it to the tether anchors ==>
page 183.
A toddler or child is usually too large for an infant restraint if it is
more than one year old and weighs more than 20 lbs. (9 kg) .
Toddlers and children who are older than one year up to about 4
years old and weigh more than 20 lbs (9 kg) up to 40 lbs. (18 kg) must always be properly restrained in a child safety seat certified for their
size and weight=>
page 173, fig. 148 and => page 174 , fig. 149.
The airbag on the passenger side makes the front seat a potentially dangerous place for a child to ride. The front seat is not the safest
place for a child in a forward-facing child safety seat . It is a very
dangerous place for an infant or a larger child in a rearward -facing
seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a collision or other emergency situa­
tion.
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates. 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 install rear-facing child safety seats on the rear seat.
• 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 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.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 135, "Safety belts",
=> page 145, "Airbag system" and=> page 167, "Important things
to know".
& WARNING
If exceptional circumstances require the use of a forward-facing
child restraint on the front passenger's seat, the child's safety and
well-being require that the following special precautions be taken:
• Make sure the forward-facing seat has been designed and certi­
fied by its manufacturer for use on a front seat with a passenger
front and side airbag. ...

& WARNING !continued)
• Always follow the manufacturer's instructions provided with
the child safety seat or infant carrier.
• Always move the front passenger seat into the rearmost posi­
tion of the passenger seat's fore and aft adjustment range, and as
far away from the airbag as possible before installing the child
restraint.
• Always make sure that nothing prevents the front passenger's
seat from being moved to the rearmost position in its fore and aft
adjustment range .
• Always make sure the backrest is in 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.
• If the light does not stay on, perform the checks~
page 156,
uMonitoring 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. •

Child Safety
Booster seats and safety be lts
Properly used booster seats can help protect children
weighing between about 40 lbs. and 80 lbs. (18 kg and
36 kg) who are less than 4
ft. 9 in. (57 inches/1.45 meters)
tall.
Fig . 150 Rear seat:
child properly
restrained in a booster
seat
The vehicle's safety belts alone will not fit most children
until they are at least 4 ft. 9 in. (57 inches /1.45 meters) tall
and weigh about 80 lbs. (36 kg). Booster seats raise these
children up so that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt can help
protect them in a crash.
- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt
midway over the child's shoulder. If you must transport
an older child in a booster seat on the front passenger
seat, you can use the safety belt height adjustment to
help adjust the shoulder portion properly.
- Always make sure that the shoulder portion of the safety
belt neve r rests against or across the child's neck.

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.
- Gu ide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.

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 pul ling 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).

LATCH Lower anchorages and
tethers for children
Child Restraint System anchors and how are
they related to child safety
T o prov ide a simpler and more practicable way to attach the child
restra int on the vehicle seat, Federa l regulations require spec ia l
lower anchorages in vehicles and devices on new child restraints to
attach to the vehicle anchorages .
The combination of the tether anchorages and the lower anchor ­
ages is now generally called the
LATCH system for " Lowe r Anchor­
ages and Tethers for Children ."
Forward -facing child restraints manufactured after September 1,
1999, are required by U .S . federa l regu lations to comply with new
chi ld head movement performance requirements . These new
performance requiremen ts make a te ther necessary on most new
chi ld seats .
I nstalling a child restraint that requires a top tether without one can
seriously impair the performance o f the child restra int and its abi lity
to protect the child in a collision . Installing a child restraint that
r equires a top tethe r w ithout the top tether may be a v iolat ion o f
state law .
Ch ild restra int manufactu rers offer LATCH lower a nchorages on
their child seats with hook -on or push -on connectors attached to
adjustable straps .
I n addition to the LATCH lower anchorages, these ch ild restraint
systems usually require the use of tether straps to he lp keep the
chi ld restraint firmly in place .
& WARNING
Improper installatio n of child restraint s will increase the risk of
injury and death in a crash .

- Attach both hook-on connectors with the spring catch release on the child safety seat onto the LATCH lower
anchorage so that the connectors lock into place
~ fig. 154.
- Pull on the connector attachments to make sure they are properly attached to the LATCH lower anchorage.
- Pull straps tight following the child restraint manufac ­
turer's instruct ions.
Releasing
- Loosen the tension on the straps following the child
restraint manufacturer's instructions .
- Depress the spring catches to release the anchorage
hooks from the lower anchorages.
Remember: Use tether straps to help keep the child restraint firmly
in place .
& WARNING
Improper use of the LATCH system can increase the risk of serious
personal injury and death in an accident.
• These anchors were developed only for child safety seats using
the "LATCH" system.
• Never attach other child safety seats, belts or other objects to
these anchors.
• Always make sure that you hear a click when latching the seat
in place. If you do not hear a click the seat is not secure and could
fly forward and hit the interior of the vehicle, or be ejected from
the vehicle.

A tether is a straight or V-shaped strap that attaches the top part of
a child restraint to special anchorage points in the vehicle.
The purpose of the tether is to reduce the forward movement of the child res traint in a crash , in order to help reduce the risk of head
injury that could be caused by striking the vehicle interior.

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, eng ine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le -related data
during norma l vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic cont rol 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, direction,
braking as we ll as restraint system use and performance in the
event of a crash or other condition. Stored data can only be read and
downloaded with special equip men t.
Electronic Stabilization Program (ESP)
General
The Electronic Stabili ty Program increases driving
stability.

sw itch
With ESP, control over the veh ic le is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
How ESP work s
The ESP control unit processes the fo llowing data from high-sensi ­
tive sensors : the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
t,.

actual vehicle behavior. If the two do not match, for example when
th e vehicle begins to skid, ESP brakes the appropriate wheel auto­
matical ly .
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an
understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=>
page 192. If there is malfunc ­
tion in the ABS, ESP is also inoperative.
Activating
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 188, fig. 158 returns the
system to normal operation.
Deactivating
ESP should normally be activated at all times because this ensures
optimum vehicle stability. Only in certain exceptional cases it does
make sense to deactivate Anti-Slip Regulation (ASR) or the Elec­
tronic Stability Program (ESP) by pressing the button =>
page 188,
fig. 158. Both deactivation stages can only be activated from normal
mode .
Deactivating ASR
Tap the switch. Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e .g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR.
Deactivating ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the ins trument cluster staying on permanently.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
This
deactivates the Electronic Stability Program (ESP) in addition to
ASR. No Elec tronic Stability System operation and no Anti -Slip
Regulation is available across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stable vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traffic situation permit.
& WARNING
• The limits of physics cannot be suspended by ESP. Even in vehi­
cles with ESP. you should always adapt your driving to road and
traffic conditions. This is particularly true on a slippery and wet
road . Do not be tempted by the increased safety provided to take
risks -danger of an accident!
• Please note that when ASR or ESP /ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break away -danger of skidding!

How the system works
The EDL operates automatical ly. It monitors the rotationa l speed of
