152 Child Safety
the child's body and the front of the passen­
ger compartment , the airbag can inflate com­
pletely and provide supplemental protection
in certain frontal collisions .
A WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a
booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- Always make sure to position the should­
er portion of the three-point belt over
the middle of child's shoulder.
- Never let the shoulder portion of the belt
rest against or across the neck , face,
chin, or throat of the child.
- Always make sure the lap belt portion of
the three-point belt is worn snug and
passes as low as possible across the
child's pelvis. Never let the belt pass over
the soft abdomen.
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation
c;,page 113.
-The rear side of the booster seat should
be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re ­
move the rear seat head restraint if it is
difficult to install the child seat with the
head restraint in place
¢page 65. Install
the head restraint again immediately
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.
- 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, for example the front 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 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.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
c;, page 133, 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.
- 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 can be locked wi th the convertible
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
IJll-

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 size.
A 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 rear-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.
- 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 or infant carriers on the rear seat.
- Forward-facing child safety seats or in­
fant carriers installed on the front pas-
Child Safety 153
senger's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child.
- It is safer to install a forward-facing
child safety seat on the rear seat.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
c=> page 143. Special
precautions apply when installing a child
safety seat on the front passenger seat
c=> page 12 3, Child restraints on the front
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
c=> page 133, 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.

154 Child Safety
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
w ith 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.
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 Lacking 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 seating position .
.,. Guide the safety belt back into the retractor
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 of the retractor. The con­
vertible locking retractor is now activat ed.
.,. Make sure that the red release button is fac­
ing away from the child restraint so th at i t
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). .,.

162 Intelligent technology
ESP includes and/or works together with the
anti-lock brake system (ABS), brake assist sys­
tem and anti-slip regulation (ASR). ESP is
switched on all the time. In certain situations
when you need less tract ion, you ca n sw itch
off ESP by pressing the button [g] _ Be sure to
switch ESP on again when you no longer need l ess traction .
Anti-lock b raking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the b rake pedal ind icates that
the system is he lp ing you to b ra ke the vehicle.
Br ake a ssist system
The brake assist system can decrease braking
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations. You must press and hold the
brake peda l until the si tuation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road co ndit io ns. This makes it easier to
start, ac celerate and drive up hills.
Electronic differential loc k (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel d rive*. This funct ion is available up
to abo ut 60 mph (100 km/h).
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from ove rheating . EDL w il l switch on aga in au­
tomatically when conditions have returned to
n o rmal.
& WARNING
- ESP, A BS, ASR an d EDL cannot ove rcome
the laws of physics . This is espec ially im ­
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately cha nge your speed to matc
h the road and t raffic
conditions. Do not let the increased safe­
ty provided by these systems tempt you
to take risks. Do ing so w ill increase the
ris k of a loss of veh icle control , co llision
and serious pe rsonal inj uries .
- Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle inc reases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESP, ABS, the brake assist system, EDL an d ASR cannot prevent collisions.
- Always accelera te with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work correct ly when
all four wheels are equipped with identi­
cal tires. Diffe rent tire sizes can lead to a
reduction in engine powe r.
- You may hear noises when the systems
descr ibed are working .
- If the indicator light
D] or m (USA
mode ls)/ KC] (Canada models) appears,
t here may be a malfunction~

The ESP is automat ically activated whe n the
engine is started, and it performs a se lf-test .

As soon as the test is completed, the system
is in normal operating mode.
Switching off
E SP should normally be activated at all times
because this ensures optimum vehicle stabil i­
ty. In certa in situations, it might make sense
to a llow some slip . For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Press the
[!I button . The ESP indicator light I)
turns on and S tabil isat ion prog ram off ap­
pears in the d isp lay. ASR deact ivates com­
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
S wi tc hing on
Press the [!I button again. The message S tab i·
li sa tion p rogram on
appears briefly in the dis­
play.
A WARNING
You should only sw itch the ESP off if your
driving ability and the traffic s ituation per­
m it. Please note that when ESP/ASR is de­
act ivated, the drive whee ls can sp in on icy
and slippe ry roads and the vehi cle can
break away - danger of skidding!
(j) Tips
If A udi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
sw itch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and d riving habit s
The brakes on today's automobi les are st ill
subject to wear, depending largely on operat­
ing cond itions and dr iving habits
q .&. . On ve ­
hicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author-
Int ellig ent technolog y 163
ized Audi dea ler more often than specified in
the
W arra nty & M aintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the b raking
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 cont inuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
speed, braking force and outs ide cond it ions
such as temperature and humidity.
Mo isture o r road sal t
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu­
lar intervals so as to improve react ion time
when brak ing on wet surfaces. You, the driver,
will not not ice anything.
Under certain conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the b ra ke pads or remove any ice coatings.
The effectiveness of the brakes ca n be reduced
when the vehicle is driven on a salt-cove red
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from brake d iscs and pads w ith a few cautio us ap­
plications o f the b ra ke
¢ .&, .
Corrosion
T here may be a tendency for di rt to b uild up
o n the brake pads and corros ion to fo rm on
the d iscs if the car is not d riven regu larly or
o nly for short tr ips w ith litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads and d iscs by braking
firmly a few times from a moderately high
speed ~.&. . .,.
•
•

However, do not expect that the ABS shortens
braking distance under
all circumstances.
When driving on grave l or on newly fallen
snow on top of icy surfaces, braking distance may be even longer, therefore, under these
circumstances, it is especially important that
you dr ive slowly and with great care .
How th e ABS syste m work s
An automatic check is made when a speed of
about 4 mph (6 km/h) is reached. When this
happens, a pumping noise can be heard .
If an individua l wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that wheel from locking.
This automatic adjustment process will cause
a
s light vib ration of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traff ic condi­
tions .
A WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction. Always adjust your dr iv­
ing speed according to the road and traffic
conditions . Do not let the extra sa fe ty af ­
forded bytheABStemptyou into taking
extra r isks. The ABS cannot overcome the
laws of physics.
(D Tips
- If ABS is not functioning properly, a
warning light will come on. See
¢ page 18.
- If a fault occurs in the ABS, the EDL is al ­
so not functioning . This is indicated by
the ABS warning light.
Brake assistant
The broke assistant is designed to achieve the
optimum broking effect .
The brake assistan t helps to increase the ef­
fective
b raking power and thus to achieve a
shorter stopping distance . If the driver
Int ellig ent technolog y 165
presses the brake peda l very quick ly, the brake
assistant automatically boosts the braking
force to the max imum level, up to the po int
where the anti-lock brake function (ABS) inter­
venes to stop the whee ls from locking. You
shou ld then keep the brake peda l pressed un ­
t il the vehicle has braked to the required
speed. The brake assistant switches itself off
as soon as you release the b ra ke peda l.
The brake ass istant wi ll not be operative if
there is a ma lfunction in the ABS.
A WARNING
P lease remember that the acc ident risk a l­
ways increases if you drive too fast, espe­
cially in corners or on a slippe ry road, o r if
you follow the vehicle ahead of yo u too
closely . An increased accident risk cannot
be compensated even by the brake assis ­
tant, so always mainta in a safe speed.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed .
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system deve lops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven-
tiona l power steering system, providing a
constant steering support force that is no
-
l onge r proportionate to the vehicle speed. ..,.

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Maintenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Ap plies to vehicles: with diesel partic ul ate filter
The diesel particulate filter filters nearly al l of
the soot part icles out of the exhaust. The fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it­
self (for example, because you are only driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter illuminates
c> page 22.
A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system a rea or a fire could
start.
(D Tip s
-When the diesel particulate filter be­
comes saturated, the engine speed in­
creases to approximate ly 1,500 rpm
while the vehicle is in motion to init iate
the cleaning of the diesel particulate fil­
ter a utomatically without the warning
l amp lighting up . If the warning lamp
Dri vin g and en vironm ent 171
Ill sti ll appears, you shou ld drive to a
qualified workshop .
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low -lying parts such as spo ilers and exhaust
system parts do not bottom out and get dam­
aged.
This is espec ially true for veh icles with low­
slung chassis (sports chassis) and fully loaded
vehicles.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise Levels.
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
If you ant ic ipate wha t you need to do next and
drive economically, you can easily cut your
fuel consumptio n by 10-15 percent . This sec­
tion wi ll give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
