Child Safety
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a collision or other emergency situa­
tion .
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag 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 inflates - even with an Advanced Airbag
System .
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will sma sh the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always install rearward-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 circumstances and
the PASSENGER AIR BAG
OFF light does not come on and stay on,
immediately install the rearward-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer .
• Always read and heed all WARNINGS whenever u sing a child
restrained in a vehicle is being used=>
page 190, "Safety belts ",
=> page 200, "Airbag system " and => page 222, "Important
things to know ".
& WARNING
If exceptional cir cumstances require the use of a forward-facing
c hild restraint on the front passenger's seat, the child' s safety and
well-being require that the following special precautions be
taken:

& WARNING (continued)
• Make sure the forward-facing seat has been designed and certi­
fied by its manufacturer for use on a front seat with a passenger
front and side airbag.
• Always follow the manufacturer's instructions provided with
the child safety seat or infant carrier.
• Always move the front passenger seat into the rearmost posi­
tion of the passenger seat's fore and aft adjustment range, and as
far away from the airbag as possible before installing the child restraint.
• Always make sure that nothing 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 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.
• If the light does not stay on, perform the checks~ page 211,
"Monitoring the Advanced Airbag System".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay
on whenever the ignition is switched

Booster seats and safety belts
Properly used booster seats can help protect children
weighing between about40 lbs. and 80 lbs. (18 kg and
36 kg) who are less than 4
ft. 9 in.
(57 inches/1.45 meters) tall.
Fig. 208 Rear seat:

restrained in a booster
seat
The vehicle's safety belts alone will not fit most children until
they are at least 4 ft . 9 in . (57 inches/1.45 meters) tall and
weigh about 80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass properly
over the
stronger parts of their bodies and the safety belt can help protect them in a crash.
- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat .
- Always position the shoulder portion of the safety belt
midway
over the child's shoulder .
- Always make sure that the shoulder portion of the safety
belt never rests against or across the child's neck.

Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat. -
Slowly pull the belt
all the way out.
- Route it around or through the child restraint 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 convertible locking
retractor is now activated.
- Make sure that the red release button is facing 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).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
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 crash.

--------------------------------------------------' "---.L==--
The system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integ rated in the elec­
tronic stabilization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertical axis, vehicle acceleration in the
fore-and-aft and lateral directions, the brake pressure, and the
steering angle are all measured .
Th e direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is con tinually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabilized by the forces acting on the whee l during
brak ing.
If the vehicle is oversteering (the vehicle turns too sharply
and the rear wheels slide toward the outside of a curve), the brakes
are mainly applied on the wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering (the vehicle does not turn
sharply enough and pushes out of a curve), the brakes are applied as
needed on the wheel that is on the inside of the curve or additionally
on the other wheels. An acoustic signal indicates when ESP brake
application cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system =>
page 245. If the Anti- Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
w ill perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode.
Controls and equip­
ment Safety first Vehicle operation
You can activate a
deactivated ESP or deactivated ESP/ ASR if required
by pressing the =>
page 240, fig. 214 => page 240, fig. 213 button.
When they are activated, the message
ESP/ ASR on appears briefly
in the display.
Deactivating
The ESP should normally be activated all the time. If necessary, you
can deactivate Anti-Slip Regulation (ASR) or the Electron ic Stabiliza ­
tion Program (ESP) by press ing the button =>
page 240, fig. 214 .
• Deactivating ASR: Tap the button . In certain exceptional s itua­
t ions (e.g. driving with tire chains), the Anti-Slip Regu lation (ASR) can
be deact ivated =>
page 242. The message ASR off appears in the
display as we ll.
• Deactivating ESP/ASR Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appea rs in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the
laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions . Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks.

Vehicle care Do-it-yourself service Technical data

Intelligent t echnology
---------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors=>
page 245. If a not iceab le
slip is detected at the wheels (e.g. on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
Electronic limited slip differential
In vehicles w ith front wheel drive *, an e lectron ic lim ited slip d ifferen­
tial engages when driving on curves . The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. T his m ini­
m izes sliding on the front wheels and enables precise and neutral dr
iv ing t hrouge curves. The electronic lim ited slip differentia l does
no t engage whe n driving in we t cond it io ns or snow.
& WARNING
• Wh en acc elerating on slipp ery s urface s, such a s on ice or snow,
always be careful when depre ssing the accele rator pedal. Even
with the EDL and the electroni c limited slip differential working,
the dr ive wh eels can spin and reduce you r ability to control your
c ar . -Ri sk of cra sh!
• The increased safet y afforded b y EDL and the electronic l imited
slip differ ential d oes not mean th at you can take safety risks .
Alw ay s adapt your d riving st yle to the road c onditions and traffi c
si tuation.
[ i ] Tips
If a fa ult occurs in the ABS, the EDL is also not funct ioning. This is
ind icated by the ABS warn ing light=>
page 16 . •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is a ccelerating.
General notes
T he Anti-Slip Regu lation System (ASR) is in tegrated in the electronic
stabilization program (ESP) . When the veh icle starts up and acceler­
a tes, the wheels are preven ted from sp inning by adjust ing the engine
power to match the amount of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervent ion.
With the a id o f the ABS sensors=>
page 245, ASR moni tors the speed
of the driven wheels. If the wheels start to spin, engine torque is
reduced automatically unti l the tires find enough grip to lock onto
the road s urface. The system is active across the entire speed range . .,

Intelligent technology
--------------------------------------------------' "---.L==--
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self-test. You can activate a deactivated ASR if required by
pressing the=>
page 240, fig. 214 button. When it is activated, the
message
ESP/ASR on appears briefly in the display .
Deactivating
You can deactivate the ASR if required by pressing the button (for less
than 3 seconds) =>
page 240, fig. 214. With the ASR deactivated , the
ESP check light comes on, see=>
page 14 . The message ASR off
appears in the display as well. The ASR can be deactivated at any
speed .
The ASR should normally be activated a ll the time. Only in certain
exceptional situations when some slip is desirable does it make sense
to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
When the abnormal situation is over, you should activate the ASR again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[I] Tips
To ensu re that the ASR works properly, all four whee ls must be fitted
with ident ical t ires. Any differences in rolling radius of the t ires can
cause the system to reduce eng ine power when this is not desired.

Safety first
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending la rgely on ope rating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking effect of the engine. This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when brak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.

Functioning of Anti-Lock Brake System
(ABS}
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents the
w heels from
locking whe n the brakes are applied . This means t hat t he
vehicle rema ins steerable and is less likely to skid.
With ABS you do not need to pump the brake. Ju st hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance under all
circu mstances. When d riving on gr ave l o r on new ly falle n snow o n top
of icy s urfaces, braking distance may be even longer, therefore, under
t he se c ir cu mstances, i t is especially importa nt that you dr ive slowly
and with great care.
How the ABS system works
An a utomat ic check is made when a speed of about 12 mph (20 km/h)
is reached. When this happens, a pumping noise can be heard.
If an individ ual w heel beg ins to rotate too slow ly in relat ion to vehicle
speed and tends to lock, t he ABS automat ic al ly reduces brake pres­
sure to prevent t hat wheel from locking .
Thi s automatic adjustment process w ill cause a
slight vibrat ion of
t he bra ke ped al and some noises to aler t you th at vehicle s peed mus t
be adapted to existing road and traff ic conditions.
& WARNING
Although the ABS is very effective , always remember that braking
capability i s limited by tire traction . Always adjust your driving
speed acco rding to the road and traffic condition s. Do not let the
extra safety afforded by the ABS tempt you into taking extra risk s.
T he ABS cannot overcome the laws of physics .
Controls and equip­ ment Safety first Vehicle operation
(I] Tips
•
If ABS is no t fun ct io ni ng prope rly, a wa rning light will come on .
See =>
page 16.
• If a fault occurs in the A BS, the EDL is also not functioning . This is
indicated by t he ABS warn ing light .•
Brake assist
Brake assist is designed to achieve the optimum braking
effect.
Bra ke ass ist helps to i ncrease the effe ctive br aking power and thus to
achieve a shorte r stopping distance . If the d river presses the brake
peda l very quickly, brake assist automatically boosts the bra king
force to the max imum level, up to the po int whe re the anti-lock b rake
function (ABS) intervenes to stop t he wheels from locki ng . You
should then keep the br ake peda l pressed unti l the ve hicle has braked
to the required speed . Brake ass ist switches itself off as soon as you
re le ase the br ake pedal.
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow the vehicle ahead of you too clo sely. Increased ri sk of an
accident cannot be compensated for even by brake assist , so
alway s maintain a safe speed. •
