Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear sea ts and the fron t
passenger can be locked wi th the convertible
locking retractor to properly secure child
safety seats .
The safety belts emergency lock ing retractors
for the rear seats safety belts and for the
front passenger's seat safety belt have a con ­
ve rtible locking retractor for child restraints.
Child Sa fet y 215
The safety belt must be locked so that be lt
webbing cannot unree l. The retractor can be
activated to lock the safety belt and prevent
the safety belt webbing from loosening up
during normal dr iving . A child safety seat can
only be properly installed when the safety belt
i s locked so that the chi ld and child safety
seat w ill stay in place .
Always remember: Even though your vehicle is equipped with an Advanced Airbag system, all
ch ildren, especially those 12 years and young­
er, shou ld always r ide in the back seat proper­
ly restrai ned fo r the ir age and size.
A WARNING
Improperly installed chi ld safety seats in­
crease the risk of serious personal injury
and death in a collision.
- Always ma ke sure that the safety belt re­
tracto r is loc ked when installing a child
safety seat . An unlocked safety belt re­
tractor cannot hold the child safety seat
in place during normal dr iving or in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not sitt ing in it.
A loose child safety seat can fly around during a sudden stop or in a collision .
- Always make sure that the rear seat
backrest to which the center rear safety
be lt is attached is securely latched when­
eve r the rea r center safety belt is being
used to secure a ch ild restra int.
- If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­ rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear-fa cing child safety
seats or infant carrie rs on the front pas ­
senger seat . A child will be serio usly in­
jured and can be killed when the passen­ ger airbag inflates.

seat -some important things to know.
A 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 195, Moni­
toring the Advanced Airbag System.
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child. -
Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash .
A WARNING
-Forward-facing child restraints:
- Always make sure the forward-facing
seat has 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 re­ straint up, against or very near the in­
strument 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 .
A 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 exception-
al circumstances.
~

-A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System . The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­
ploy 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, immedi­
ately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your Audi dealer.

LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
To p rov ide a simpler and more practicable way
to a ttach the child restra int on the vehi cle
seat, Federal regulat ions req uire spec ia l lowe r
anchorages in vehicles and devices on new
child restraints to attach to the vehicle ancho­
rages.
T he combination of the tether anc horages and
the lowe r anchorages is now genera lly ca lled
t h e
LATCH system fo r "Lower Anchorages and
T ethers for Child ren."
F o rward-facing chi ld restrai nts ma nufactured
after September 1, 1999, are requ ired by U .S .
f edera l regu lations to comply with new child
head movement performance req uirements.
These new performance req uirements make a
tether necessary on most new child seats.
Installing a child restraint that requires a top
tether without one can seriously impair the performance of the c hild restra int and its abil­
ity to protect the child in a coll is ion. Insta lling
a chi ld restraint that requires a top tether
without the top tether may be a violat ion of
state law.
Child restraint manufacturers offer LATCH
lower anchorages on their child seats w ith
hook -on or push-on connectors attached to
adjustable straps .
In add ition to the LATCH lower anchorages,
these chi ld restraint systems usually require
the use of tether straps to he lp keep the chi ld
rest raint firmly in place.
A WARNING
-Imp roper installat ion of ch ild restra ints
will i ncrease the r is k of injury a nd death i n
a crash.
-

220 Child Safe ty
A ll child restraints man ufactured after Sep­
tember 1, 2002, must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage points
are on ly intended for installation and attach­
ment of child restraints specifically certified
for use w ith
LATCH l ower anchorages . Child
restra ints that are not equipped with the tow­
er anchorage attachments can still be instal­ led in compliance with the ch ild restra int
manufacturer's instruct ions on using vehicle
safety belts.
A WARNING
Improper use of LATCH lower anchorages
can ca use serio us pe rsonal injury in an ac­
cident.
- Always carefully follow the ch ild re­
strain ts manufac turer's instruct io ns for
proper installation of the child restraint
and proper use of the lower anchorages
or safety belts in your vehicle .
- Never secure o r attach any l uggage or
ot her items to the
LATCH lower ancho­
rages.
- Always read and heed the important in­
formation about child restraints in this
chapter and WARNINGS

You may find it easier to install c hild re­
straints equ ipped with hooks attached to
straps witho ut the g uidance fixtures in place.
If this is the case, remove the guidance fix­
tures by pulling them off the anchorages. However, the guidance fixtures can help you
to locate the
LATCH anchorages . ..,.

_& WARNING
Improper use of tether anchorages or low­
er anchorages can cause serious personal
injury in a crash.
- Always carefully follow the child re­
straint manufacturer's instructions for
proper installation and use of child re­
straint systems.
- Never use the
LATCH or tether anchorag­
es to attach safety belts or other kinds of
occupant restraints.
- Child restraint tether attachments and
lower attachments are only designed to
secure a child restraint that has been
equipped to use these anchorages.
- Tether anchorages and lower anchorages
are designed to withstand only those
loads imposed by correctly fitted child
restraints. Under no circumstances can
they be used safely for adult or child
safety belts or harnesses.
- Never mount more than one child re­
straint to a single tether or to a lower an­
chorage point. Attaching two child re­
straints to a single anchorage point can
cause the anchorage to fail and cause se­
rious personal injury in a crash.
(D Note
-Remove the guidance fixtures before
folding the rear seatback to prevent
damaging the seat cushion.
- If you leave the guidance fixtures instal­
led for several days, they could leave a
mark on the upholstery on the seat cush­
ion and backrest in the area that the
guidance fixtures were installed. The up­
holstery would also be permanently
stretched around the guidance fixtures.
This applies especially to leather seats.

p roperly insta ll the tethe r.
& WARNING
A child in a rearward -facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be ki lled if
the front a irbag inflates - even with an Ad­
vanced Airbag System.
- The inflating airbag will hit the child safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armrest, or door .
- A tight tether or other strap on a rear­
ward-facing child restra int attached to
the front passenger seat can put too much pressure on the weight-mat in the
seat and register a heavier weigh t in the
Advanced Airbag System. The heav ier 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 ser ious or
even fatal injury to the ch ild.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the

The vehicle is then stabilized by the forces act­
ing on the whee l during braking. If the vehicle
is
oversteering (rear tends to sk id out of the
turn), the brakes are ma inly applied on the
wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering
(tendency to slide out of the curve), the
brakes are applied as needed on the whee l
that is on the ins ide of the curve or addit ional­
l y on the o ther wheels. An acoustic s ignal indi­
cates when ESC b rake app lication cuts in

The system operates across the entire speed
range in combination with the ABS system
¢ page 229. If the Anti-Lock Brake System
(ABS) malfunctions, the ESC wi ll be out of ac­
tion as well .
Activating
When you turn on the engine, ESC w ill auto­
mat ica lly be act ivated and will perform a se lf­
test. As soon as the test is comp leted, the sys­
tem is in normal operating mode.
Offroad mod e
ESC should normally be ope rated in normal
mode because this ensures maximum vehicle
stability. If necessary, you can act ivate the
ESC offroad mode by pressing the but to n
¢ fig . 232 to obtain maximum traction and
braking ability when driving
off paved roads at

The ESC offroad mode can be useful in the fo l­
low ing except ional situations when slip or a
h ighly effective differential locking function is
des irable . Examp les:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
whee ls severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck . When the

H ill desc ent control
The hill descent control is switched on in ESC
offroad mode . When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides ass istance by automatically apply ing the
brakes to keep vehicle speed constant. The ve ­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force. Hill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also axle
art iculation).
Hill descent contro l operates both d riving for­
ward and in reverse. Active hill descent con­
tro l is deactivated by pressing the accelerator
pedal until the condit ions for activation al­
ready listed are met again .
A WARNING
--
- The Electronic Stabilization Contro l is
neverthe less s ubject to the laws of phys­
ics. It is part icularly important to pay at­
tention to this fact on wet and slippe ry
roads . It i s therefore important that you
always adapt your dr iving to the cond i­
tion of the road and traffic conditions . Do
not a llow the increased safety provided
by the E lectronic Stabilization Contro l
system to lull you into accepting addi­
tional safety risks .
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pe ry road, the wheels may have an in­
creased tendency to sp in and the vehicle
may b reak away - dange r of skidding!
~

-Stability is limited in the ESC offroad
mode.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General notes
The electronic differentia l lock (EDL) helps the
car to start movi ng, accelerate and climb a
gradient on surfaces providing poor or almost
no grip. Without EDL, this would be difficult,
if not impossible.
H ow the system works
The ED L opera tes automatically. It monitors
the rotat iona l speed of wheels w ith the help
of the ABS sensors¢
page 229. If a noticea­
b le
slip is detected at the wheels (e .g. on slip ­
pery ground
on one side), the spinning whee ls
are braked and power is transferred to the
other wheels. This is done up to a speed of
about
60 mph (100 km/h) . Noises from the
brake system s ignal that wheel sp in is being
controlled.
Dri ving off
When driving off, always be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
w ith less gr ip, apply
plenty of throttle until
the car starts to move.
O verheating of br akes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads on this wheel, the EDL cuts out tempo­
rarily . T he vehicle remains operational and be­
haves in the same way as a veh icle w ithout
E DL.
As soon as the brake has cooled down, EDL
switches on again automatically .

Int ellig ent technolog y 22 7
Even with the EDL working, the drive
wheels can spin and red uce your ab ility
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your driving style to
the road condit ions and traffic situation .
(D Tips
If a fault occurs in the ABS, the EDL is also
not functioning. This is ind icated by the
ABS warning light¢
page 18.
Anti-Slip Regulation System (ASR )
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regu lation System (ASR) is inte­
grated in the Electronic Stabilization Control
(ESC). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the
amount of grip available from the road sur­
face .
How the sy stem works
ASR performs automat ically, i.e. without the
driver's intervention. With the aid of the ABS
sensors ¢
page 229, ASR monito rs the speed
of the dr iven wheels .
If the wheels start to
spin, engine torque is red uced automat ically
unt il the t ires find enough grip to lock onto
the ro ad surface. The system is active across
the entire speed range.
T he ASR works in conjunction with the ABS. If
a malfunc tion s hou ld occu r in the ABS, the
ASR wi ll also be out of act io n.
A WARNING ~
The increased safety affo rded by ASR does
not mean that you can take safety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation.
