176 Child Safety
-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 .
- Never let a child stand or kneel on any
seat.
- Never let a child ride in the cargo area of your vehicle .
- Always remember that a child leaning
forward, sitting sideways or out of posi­
tion in any way during an accident can be
struck by a deploying airbag . This will re­
sult in serious personal injury or death .
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces the
PASSENGER AIR BAG OFF light
must come on and stay on, whenever the
ignition is switched on.
- If you must install a booster seat on the
front passenger seat because of excep­
tional circumstances the
PASSENGER
AIR BAG OFF
light must come on and
stay on, whenever the ignition is switch­
ed on.
- 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 .
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger's seat can be locked with the con­
vertible locking retractor to properly secure
child safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the front
passenger's seat safety belt have a con­
vertible locking retractor for child restraints.
The safety belt must be locked so that belt
webbing cannot unreel. The retractor can be activated to lock the safety belt and prevent
the safety belt webbing from loosening up
during normal driving. A child safety seat can
only be properly installed when the safety belt
is locked so that the child and child safety
seat will stay in place .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young­
er, should always ride in the back seat proper­
ly restrained for their age and weight.
& WARNING
=
Improperly installed child safety seats in­
crease the risk of serious personal injury
and death in a collision.
-
-Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat
in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting 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
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
-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 rearward-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen- ger airbag inflates.
~

178 Child Safety
-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 rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
Activating the convertible locking
retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor :
.., Place the child restraint on a seat, prefera­
bly on the rear seat.
.., Slowly pull the belt
all the way out.
.., Route it around or through the child re­
straint 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 sea ting position .
.., Guide the safety belt back into the retrac tor
until the belt lies flat and snug on the child
safety seat . ..,
You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to pull the belt out o f the retractor. The con­
vertible locking retractor is now activated .
"" Make sure that the red release button is fac­
ing 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).
A WARNING ~
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash .
- Always make sure that the safety belt re-
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat
in place during normal driving or in a
cra:;;h.
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation .
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

• Depress the spring catch on the hook and
release it from the anchorage .
(D Note
If you leave the child restraint with the
tether strap firmly insta lled for several
days, this cou ld leave a mark on the up­
holstery on the seat c ushion and backrest
in the area where the tether strap was in­
stalled. The upholstery would a lso be per­
manently stretched around the tether
strap. Th is applies especially to leather
seats.
Using tether straps on rea rward-facing
child restraints
Currently, few rearward-facing child rest raint
systems come with a tether . P lease read and
heed the child restraint system manufactur­
er's instructions carefully to determine how to properly instal l the tether.
A WARNING

186 Intelligent technology
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
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch
off ASR by p ress­
i ng the bu tto n
[ru ¢ page 188, fig. 176 or
¢ page 188, fig. 177. Be sure to sw itch ASR
on aga in when yo u no longer need less t rac­
tion .
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braki ng. The veh icle can still be steered
even d uring h ard br aking. Apply ste ady p res ­
sure to the brake pedal. Do no t pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assis t system can decrease b ra ki ng
d ista nce. It increases braking power w hen the
d river p resses the brake pedal quic kly in eme r­
gency situations . You must p ress and hold the
brake peda l until the situation is over. In
vehicles w ith adapt ive cru ise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start , accelerate and drive up hills.
Electronic differenti al lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if t he vehicle is equipped with
all-w heel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL wi ll switch on again au-tomat
ica lly when conditions have ret urned to
no rma l.
Dynamic steering*
On vehicles wi th dynam ic steering*, ESC he lps
st abi liz e the steer ing in cr itical situ ations.
Electronic interaxle differential lock* /
selective wheel torque control*
T he elec troni c int eraxle differentia l lock (front
whee l dr ive) o r th e se lec tive whee l torque
control (all-whee l dr ive) oper ates when dr iv ­
ing t hro ugh curves. The front wheel on the in ­
side of the c urve or both whee ls on the inside
of the c urve are b raked se lectively as needed.
This m inimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when dr iving in wet o r snowy cond itions.
A WARNING
- ESC, ABS, ASR, EDL dynam ic steering*
a nd the ele ct roni c interaxle d ifferential
lo ck* /se lective whee l torque con trol *
cannot ove rcome the laws of physics .
This is especially important on sli ppery
or wet roads.
If the systems beg in acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions . Do not
let the increased safety prov ided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle cont ro l, col lision and ser ious pe r­
sonal injur ies.
- Always ada pt your speed to road, traffi c
a nd wea ther conditions. The r isk of los-
ing con trol of the vehicle i ncreases when
d riving too fast, es pec ia lly through
curves and o n slippe ry or wet roads, an d
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steer ing* and the
e lectronic inte raxle differentia l lock*/se­
lec tive whee l to rque control* cannot p re-
-
vent co llisi ons. ~

-Always acce lerate with specia l care on
even, smooth surfaces s uch as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways help to reduce the risk of loss of ve­ hicle control.
(0 Tips
- ABS and ASR on ly work correctly when
all four wheels are equ ipped w ith ident i­
ca l tires. Different tire s izes can lead to a
reduct ion i n eng ine power.
- You may hear noises when the systems
described are wo rking .
- If the indicator light D] or m!S (USA
models) ;tiJ (Canada models) appears,
the re may be a malfunct ion

Braking
What affects braking efficiency?
New brake pad s
During the first 250 mi les (400 km), new
brake pads do not possess the ir full brak ing
effect, they have to be "broken in" first¢ .&,.
You can compensate for this slightly reduced
braking power by p ushing harde r on the brake
pedal. Avoid heavy brak ing loads dur ing the
break-in pe riod.
Oper ating cond ition s and driving habit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat ­
ing co nd it ions and driving hab its
¢ .&, . On
vehicles that are either driven most ly in stop-
and-go city traff ic or are dr iven hard, the
lilJ,,

brake pads should be checked by your a uthor ­
ized Audi dealer more often than specified in
the
War ranty & M aint enance booklet . Failure
to have your brake pads inspected can res ult
in reduced brake performance.
On steep slopes, you shou ld use the braking
effect of the engine . This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously . Pump the brakes at inter ­
vals.
Operating no ise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Effect of w ater and ro ad salt
In certain sit uations, for example after driving
through water, in heavy rain, after overnight
condensation or after washing your car, the brak ing effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be dried first with a few careful
brake app lications.
At h igher speeds and with the w indshield w ip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This occurs at regula r intervals without the
d river 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 a re not used . L ikew ise,
you clean off a ccumulated sa lt coating from
brake discs and pads with a few ca utious ap­
p lications of the brake
c:> .&. .
Cor rosion
There may be a tendency for dirt to bu ild up
on the brake pads a nd corrosion to form on
the discs if the car is not dr iven regular ly or
only for short t rips with little use of the
b rakes.
I f the b rakes are not used frequently, or if cor­
r osion has formed on the discs, it is advisab le
t o clean off the pads and discs by brak ing
Int ellig ent technolog y 189
firmly a few times from a moderately h igh
speed
c:> .&. .
Faults in the brake s yst em
If you shou ld notice a sudden in crease in
brake pedal trave l, then one of the two brake
c ircuits may have fai led
c:> .&. .
Lo w brake fluid l ev el
Malfunctions can occur in the brake system if
the brake fluid level is too low . The brake flu id
level is monitored elect ro nica lly.
Brake booster
The brake booster increases the pressure that
you generate with the brake peda l. It works
only when the engine is running
.c:> .&
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sa ry, the wheel may be removed for th is in ­
spect ion
c:> page 259, Changing a wheel.
A WARNING
- New brake pads don' t have the best stop­
ping power and m ust be "bro ken-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. Th is also
applies later when new pads are instal­
led.
- You should perform braking maneuvers for the purpose of cleaning the brake
system only if road conditions permit.
Other road use rs 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
gea r or l ower dr iving range . Do not ride
the brakes or hold t he pedal down too
long or too often . Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by res ting you r
foo t on the pedal when you do not intend .,..
•
•

Please start the engine soon or the system
will be turned off.
The warning ind icates that the system will be
turned off automa tically after 3 minutes. If
you wish to continue using the functions, you
have to start the engine .
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven , the battery can be­
come discharged. This happens most ly when
litt le energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To br ing t he ene rgy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular requ ire a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy ba lance has bee n restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not
a cause for concern. By increasing engine idle
speed the add itional ene rgy required is gener­
ated and the ba ttery is charged.
