If the convertible locking retracto r shou ld be
activated inadvertently, the safety belt must be unfastened and guided completely back in­
to its stowed pos ition to deactivate th is fea­
ture. If the convertible locking retractor is not
deactivated, the safety belt will gradually be­
come tighter a nd uncomfortable to wear.
A WARNING
Improperly insta lled child safety seats in­
crease the risk of ser ious personal inju ry
and death in a collision.
- Never unfasten the safety belt to deacti­
vate the convert ible lock ing retractor for
child rest rain ts while the veh icle is mov­
ing. You would not be restrained and
cou ld be ser iously injured in an accident.

LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s impler and more pract icable way
to attach the child restraint on the vehicle
seat, Federal regu lations require special lower
anchorages in vehicles and dev ices on new
child restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LA TCH system for "Lower Anchorages and
Tethers for Children ."
F orward-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 .
T hese new performance requirements make a
tether necessary on most new child seats.
I nstalling a chi ld restraint that requires a top
tether without one can seriously impair the
performance of the chi ld restraint and its ab il­
ity to protect the child in a co llision . Installing
a child restraint that requires a top tether
without the top tether may be a v iolation of
state law.
Ch ild restraint manufacturers offer LATCH
lower anchorages on their ch ild seats with
hook -on or push-on connectors attached to
adj ustable straps.
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child
restra int firmly in place .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of inju ry and death in
a crash.
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re-
Child S afety 175
straint you intend to install in your vehi­
cle.
- Never install a chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
tions require the top tether strap to be
used.
- Improper use of child restraint LATC H
lower anchorage points can lead to injury
in a collision . The LATC H lowe r anchorage
points ar e designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two ch ild restra int systems
on one LATC H lower anchorage point.
- Never secure or a ttach any luggage or
o ther item to the LATCH lower anchorag­
es.
a) Tips
In Canada, the terms "top tether" with
"lower u niversal anchorages" (or "lower
universa l anchorage ba rs") are used to de­
scribe the sys tem.
- In other countries, the t erm " ISOFIX" is
used to describe the lower a nch o rages.

Lower anchorages secure the child restraint in
the seat without using the vehicle's safety belts. Anchorages provide a secure and easy­
to-use attachment and minimize the possibili­
ty of improper child restraint installation.
A ll child restraints manufactured 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 with
LATCH lower anchorages . Child
restraints that are not equipped with the low­
er anchorage attachments can still be instal- led in compliance with the child restraint
manufacturer's
instructions on using vehicle
safety belts .
A WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefully follow the child re­
straints manufacturer's instructions for
proper installation of the child restraint
an d prope r use of the lower anchorages
or safety belts in your vehicle.
- Never secure or attach any luggage or
other items to the
LATCH lower ancho­
rages.

Tether anchors and tether straps
Fig. 151 Tet her anchors: recess flaps behind the rear
seatbacks
T he te ther anchors for the rear seating posi­
tions are located in recesses in the rear win ­
dow shel f¢
fig. 151 .
A tether is a stra ight or V-shaped st rap that
attaches the top par t of a ch ild restrai nt to
special a nchorage po ints in the vehicle.
T he purpose of the tether is to reduce the for­
ward movement of the child rest raint in a
c rash, i n orde r to help reduce the risk of head
injury that cou ld be caused by strik ing the ve­
hicle inte rior.
Fo rward facing child restraints manufactured
after September 1, 1999, are requ ired by U.S.
federa l reg ulations to comply wi th ch ild head
movement pe rformance requi rements. These
new performance requirements make a tether
necessary on most new child safety seats .
A WARNING
Improper installation of child restra ints
will increase the r isk of injury and death in
a crash.
-Always follow the instr uctions provided
by the manufacturer of the child re­
straint you intend to install in your Audi.
- Improper use of child restraint anchors
(including tether anchors) can lead to in­
jury in a coll ision. The anchors are de­
signed to withstand only those loads im­ posed by co rrectly fitt ed child restraints.
- Neve r mo unt two child rest ra int systems
on one LATC H lower anchor point.
- Never attach two child restraint systems to one tether strap o r tethe r ancho rage .
-

1 78 Child Safety
-Never attach a tether strap to a tie-down
hook in the luggage compartment .
- Never use child restraint 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 a tether or other strap is used to at­
tach a child restraint to the front passen­
ger seat, make sure that it is not so
tight, that it causes the weight-sensing
mat to measure more weight than is ac­
tually on the seat.
- The heavier weight registered can make
the Advanced Airbag 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.
-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
authorized Audi dealer.

straint if necessary).
.,. Tilt the recess flap up to expose the anchor
bracket.
.,. Attach the tether strap anchorage hook into
the opening of the tether anchorage.
.,. Pull on the tether strap hook so that the
spring catch of the hook engages .
.,. Tighten the tether strap firmly following the
child restraint manufacturer's instructions.
Releasing the tether strap
.,. Loosen the tension following the child re­
straint manufacturer's instructions.
.,. Depress the spring catch on the hook and re­
lease it from the anchorage.
(D Note
If you leave the child restraint with the
tether strap firmly installed for several
days, this could leave a mark on the up­
holstery on the seat cushion and backrest
in the area where the tether strap was in­
stalled. The upholstery would also be per­
manently stretched around the tether
strap. This applies especially to leather
seats .
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child restraint
systems come with a tether. Please read and
heed the child restraint system manufactur­
er's instructions carefully to determine how to
properly install the tether .
A 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 Ad­
vanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat ..,.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 182, fig. 153 or
~ page 182, fig. 154. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in emer­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 181
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-wheel dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
cannot overcome the laws of physics .
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traff ic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing contro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* cannot p re-
vent co llisions . ..,.

Braking
What affects braking efficiency?
New brake pads
During the firs t 250 miles (40 0 km), new
b ra ke pads do not possess their f ull braking
effect, they have to be "broke n in" first ¢.&,. .
You can compensate for th is slightly reduced
brak ing power by push ing harder on the brake pedal. Avoid heavy brak
ing loads dur ing the
break -in period .
Operating conditions and driving habits
The bra kes o n today's a utomo biles a re still
s u bject to wear, depend ing largely on operat­
ing condit ions and driving habits ¢.&,. . On
vehicles that are either driven m ost ly in stop­
and-g o city traff ic or are dr iven hard, the
brake pads should b e chec ked by your au tho r­
iz ed Audi dea ler mo re often than specified in
the
Warranty & Maintenance booklet . Failure
to h ave yo ur bra ke pads insp ect ed ca n result
in reduced brake pe rfo rmance .
On steep slop es, you sho uld use the b raking
effe ct o f the e ngine. This way, you prevent un ­
ne ce ss ary wear on the br ake sys tem.
If you
mus t use your brakes, do not hold the b ra kes
down cont in uou sly. Pump the brakes at inter­
vals.
Operating noise
N ois es m ay o ccur when br akin g depend ing on

Effect of water and road salt
In certa in situa tions, for examp le afte r dr iv ing
t hr ough wa ter, in heavy rain, after overnight
c on den sat ion or after w ashin g your car , the
braking e ffec t ca n be reduce d by mois ture o r
ice on the b rake ro to rs and brake pads . The
brakes m ust be dr ied first with a few careful
brake ap plications .
•
•

184 Intelligent technology
At higher speeds and with the windshield wip ­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet condit ions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likew ise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake¢&. .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with l ittle use of the
brakes .
If the brakes are not used frequently , or if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢,& .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢&. .
Low brake fluid le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically .
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal. It works
only when the eng ine is running .¢ &.
Brake lining w ear status
Brake lining wea r may be checked by vis ual in ­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sary, the whee l may be removed for this in ­
spection
¢ page 244, Changing a wheel.
_& WARNING
-New brake pads don't have the best stop­
ping power and must be "broken -in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving .
You can compensate for this by pressing the brake pedal more firmly . T his also
applies later when new pads are instal­ led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa ­
ter, dr iving in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
d iscs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned
off after a few care­
fu l brake applicat ions .
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can a lso affect braking efficiency .
Clean
off accumulated salt coating from
b rake discs and pads wi th a few ca reful
b rake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
flow to the front brakes is not obstruct-
ed . Otherwise the brake system could
~

overhea t red ucin g the e ffec tiveness of
t h e ent ire brake system.
- Failure of one brake circuit will impair
the bra king capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est author ized Audi dealer or qualified
wor kshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not work ing, the
brake pedal must be pressed considera­
bly harder to make up for the lac k of
booster assistance.

Winter t ires
When driving in the winte r, your ve hic le with
a ll-whee l drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea­
son t ires) for improved dr iveability a nd brak­
ing: these t ires must be mounted on
all four
wheels . See also i=>page 237, Winter tires.

Where tire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
with a ll-wheel drive

Replacing wheels /ti res
Vehicles w ith all -wheel drive must a lways
have tires o f the same size. Also avoid t ires
with d iffe rent tread depths . For details see
page
c:;> page 2 33, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
therefore best to avoid rough t racks and un­
even terrain as much as possible . Also refe r to
<=;> page 188.
A WARNING
Always adjus t you r d rivi ng to roa d and tr af­
fic co ndition s. Do no t let the e xt ra s afety
a ff orde d by all -whee l dr ive tem pt you in to
taking extra risks .
- Alt hough the all-whee l dr ive is very e f­
f ec tive, a lways remember tha t br aking
ca pacity is limited by t ire traction . Yo u
sho uld the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road s urfaces, be careful not to
dr ive too fast because the front wheels co
uld begin to slide o n top of the water
(aquaplaning). If t his should occur, you
will have no warn ing fr om a s udden in­
crease in eng ine speed as w ith a front­
wh eel drive veh icle . Always dr ive at
speeds wh ich are su ited to the road co n­
di tions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle wi th a conventiona l ener gy sys tem
is not driven for a long per io d of time, the bat­
te ry is discharged by idling current consumers
(e .g. immobilize r). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine .
Intelligent energy management in your vehi­
cle hand les the dist ribution o f electr ica l ener­
gy. Start ing ability is markedly improved and
t h e life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis contin uously de termines
t h e state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature. This determines the current
state of charge and t he power of t he battery .
Idling current management
Idling current management reduces energy
