174 Child Safety
• 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
c::;, 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)
c::;, page 177.
• If the child safety seat is equipped with a
tether strap, attach it to the tether anchors
c::;, page 183.
• Secure unused safety belts on the rear seat
c::;, page 172.
A toddler or child is usually too large for an in­
fant 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
c::;, fig. 134 and c::;, fig . 135.
The airbag on the passenger side makes the
front seat a poten tially dangerous place for a
child to ride . The front seat is not the safest
place for a child in a forward-facing child safe­
ty seat.
It is a very dangerous place for an in­
fant or a larger child in a rearward-facing seat.
A WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death in a
collision or other emergency situation.
- Children on the front seat of any car,
even with Advanced Airbags, can be seri­
ously injured or even killed when an air­
bag 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 in-
-
flates -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 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 circumstan ­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
Audi dealer.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat.
- For adjustable head restraints: adjust or
remove the rear seat head restraint if it
is difficult to install the child seat with
the head restraint in place
c::;, page 55. In­
stall the head restraint again immediate­ ly once the child seat is removed. Driving
without head restraints or with head re­ straints that are not properly adjusted
increases the risk of serious or fatal neck
injury dramatically.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
¢page 131, Safety
belts, c::;, page 140, Airbag system
and
c::;, page 166, Important things to know.
A WARNING
-
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe­
ty and well-being require that the follow­
ing special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer for use on a front seat with a passenger front and side airbag.

-Always follow the manufacturer's in­
struct ions provided with the child safety
seat or infant carrier.
- Always m ove the front passenger seat in­
to the rearmost position of the passen­ ger seat's f ore and aft adjustment range,
and as far away from the airbag as possi­
ble before install ing the child restraint.
- Always make sure that noth ing 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
upr ight position .
- Never place o r use any electrical device
(such as a laptop, CD player, electron ic
games dev ice, power inverter o r seat
heater for child se ats ) on the fr ont pas­
senger se at if the device is connected to
the 12-vo lt socket or the cigarette light ­
er socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys ­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as
a laptop, CD player, electronic games de­
vice, power inverter or seat heate r for
child seats). These may influence the
elect rical capacitance measu red by the
capacit ive passenger detection system
and can a lso fly aro und in an accident
a nd cau se se riou s person al injury.
- Make sure that the
PASSENGER AIR BAG
OFF
lig ht comes on an d stays on all the
t ime whenever the ignition is switched
on .
- If the
PASSENGER AIR BAG OFF light
does not come on and s tay on, immedi­
ately install the forward-facing child seat
at a seating posit ion on the rear seat and
have the a irbag system inspected by your
authorized Audi dealer. Child S

The vehicle's safety belts alone will not fit
most children until they are at leas t 4 ft . 9 in .
(57 inches/1.45 meters) tall and weig h about
80 lbs. (36 kg). Booster seats rai se t hese chi l­
dren up so that the safety belt w ill pass prop­
erly over the stronge r parts of the ir bodies
and t he safety be lt can he lp pro tect them in a
c rash .
.,. Do not use the convert ible lock ing retractor
when using the veh icle's safety be lt to re­
strain a ch ild on a booster seat .
.. The s houlde r belt must lie as close to the
center of the chi ld's collar bone as possib le
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck . The lap be lt must lie across the pelvis
and never ac ross the stomach or abdomen .
Mak e su re the be lt lies flat and sn ug. P ull on
the belt to tighten if necessary .
.,. If you must tra nsport an older c hild in a
booste r seat on the front passenger sea t, .._

without head restraints or with head re­
straints that are not pr operly ad justed
increases the risk of ser ious or fatal neck
injury dramat ically .
- Children on the front seat of any car,
even with Advanced A irbags, can be seri­
ously injured or even killed when an a ir ­
bag inflates .
- Never let a child stand or knee l on any
seat, for example the front seat.
- Never let a child ride in the cargo area of
your vehicle .
- Always remember that a ch ild lean ing
forward, sitt ing s ideways o r out of posi­
t ion i n any way during an acc ident can be
st ruck by a deploying airbag . This will re­
s u lt in se rious personal injury or death.
- If you must install a booster seat on the
front passenger seat because of excep­
tio nal circumstan ces the

Tether anchors and tether straps
Fig. 14 1 Tether anchors: recess flaps behind th e rear
seatbacks
The tether anchors for the rear seating posi­
tions are located in recesses in the rear win­
dow shelf
c> fig. 141
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 for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
h icle inter ior .
Forward facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
These new performance requirements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld res traints
w ill increase the risk of inju ry and death in
a c rash.
- Always follow the instructions p rov ided
by the manufacturer of the chi ld re ­
straint you intend to install in your Audi.
- Improper use o f ch ild restraint anchors
(incl uding tether anchors) can lead to in­
jury in a co llision. The anchors are de-
-
Child S afety 183
signed to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems
to one tether strap or tether anchorage.
- Never attach a tether strap to a tie -down
hook i n the Luggage compartment .
- Never use child rest raint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints .
- Never secure or attach any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.
- If you must insta ll a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the

control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EO R), installed by some manu­
facture rs fo r the express purpose o f capturing
data for retr ieval after an accident or cras h
event . EDR's a re sometimes called "crash re ­

Electronic stabilization
control (ESC)
Description
The ESC reinforces driver safety. It reduces
the r isk of slipp ing and improves driving sta ­
b ili ty . E SC detects cr itical s it u ations such as
the veh icle ove rsteer ing and understee ring or

Anti-lock braking system (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle ca n still be steered even
dur ing ha rd braking. App ly steady pressure to
the b rake peda l. Do not pump the p edal. A
puls ing in the bra ke peda l indicates t hat the
system is acting to st abil ize the ve hicle.
Brake assist system
The brake ass ist system can decrease braking
dis tance. It increases bra king power when the
drive r presses the bra ke peda l quickly in emer­
gency s ituations. Yo u m ust pres s and hol d the
brake pedal unt il the dangerous s it u at ion is

the b rake assist system is more sensitive if the
distance detected to the vehicle ahead is too

Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive

the road conditions . This makes it easier to
start, accelerate and dr ive up inclines.
Electronic differential lock (EDL)
The EDL bra kes whee ls tha t a re sp inning and

s e le ct ive w heel t orqu e cont rol *
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque
contro l (all wheel drive) operates when driving
through curves. The front whee l on the inside
of the curve or both wheels o n the inside of
the curve are braked selectively as needed .
This minimizes s liding in the front wheels and
a llows for more precise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
Post-collision bra ke ass ist
"Post-collision brake assist" can ass ist the
driver during a collision by reducing the dan­
ge r of slipp ing and further co llision and by au­
tomatic braking.
"Post-collision brake assist" functions during
front, side and rear collis ions when the a irbag
control module a detects a trigger level and
the co llision takes place at a dr iv ing speed
faster than 6 mph (10 km/h). The braking of
the vehicle happen automatically via the ESC
as long as the ESC, the hydraulic brake sys­
tem, and the vehicle electrical system are not
damaged from the coll ision.
The fo llowing activ ities override the automat­
ic braking during a collision:
- If the dr iver presses the accelerator peda l.
T here is no a utomatic braking.
- When the force on the press brake pedal is
stronger than the b raking force initiated by
the system . The vehicle is manually braked .
- When the ESC is damaged and the "post­
collision brake assist" is not availab le.

torque control cannot overcome the laws
of physics. This is espec ially important
on sl ippery o r wet roads.
If the systems
begin acting to stabili ze your veh icle, you
should immediately alter your speed to
match the road and traffic conditions . Do
not let the increased safety prov ided
tempt you into tak ing risks. This could
increase your risk of a collision.
- Please note the risk of a collision increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead .
ESC, ABS, the brake assist system, EDL,
electronic interaxle differentia l lock or
selective whee l to rque control cannot
p revent coll is ions.
- Press the acce lerator pedal carefully
when acce le rat ing o n even, slippe ry sur­
f a ces such as ice and snow. The drive
wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
col lision.
(D Tips
- ABS and ASR only function correc tly
when all four wheels are eq uipped w ith
identical tires. Different t ire sizes can
lead to a reduction in engine power.
- Yo u may hear noises when the systems
described are working .
- If the
DJ or m] (USA models) !II] (Cana ­

may be a malfunction

A WARNING
You should only sw itch the ESC off if your
driving ability and the traffic s ituation al­
low. This could increase the risk of slip­
ping.
- The stabilizing function is limited in ESC
sport mode. The driving wheels could
spin and the vehicle could swerve, espe­
cially on slick o r slipp ery road surfaces .
- T here is no vehicle stabilizat ion when
ESC/ASR are switched off.
@ Tips
-If Audi magnet ic ride is malfunctioning,
the ESC sport mode cannot be switched on or off. If ESC sport mode is activated
or ESC is switched off, it w
ill be switched
back on automatically.
- ESC sport mode cannot be switched on

Brakes
New brake pads
New brake pads do not achieve their full brak­
ing effect during the first 400 km. They must
be "broken in" first. However, you can com­
pensate fo r the slightly reduced braking force ""
