& WARNING
Not using a child safety seat, us ing the wrong child safety seat or
improperly in stalling a child re straint in crea se s the ri sk of serious
personal injury and death .
• All vehicle oc cupants and e specially children mu st always be
restrained properly whenever riding in a vehicle.
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the
vehicle or by being ejected from it during a sudden maneuver
or impact .
- An unre strained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag .
• Commercially a vailable child safety seats are requi red to
c omply with U .S. Federal Motor Vehicle Safety Standard (FMVSS )
213 (in Canada CMVSS 213 ).
- When buying a child restraint, select one that fits your child
and the vehicle.
- Only u se child restraint sy stem s that fully contact the flat
portion of the seat cushion . The child rest raint must not tip or
lean to either side . Audi does not recommend using child
s a fety seats that rest on legs or tube-like frames. They do not
provide adequate contact with the seat .

& WARNING
(co ntinued )
-Always heed all legal requirements pe rtaining to the in stal­
lation and use of child safety seat s and carefully follow the
inst ructions provided by the manufacturer of the seat you are
using.
• Never allow child ren under 57 inches (1.5 meters ) to wear a
normal safety belt . They must always be restrained by a prop er
child restraint system . Otherwise , they could sustain injuries to
the abdomen and neck areas during sudden braking maneuvers or accidents.
• Never let more than one child occupy a child safety seat.
• Never let babies or olde r children ride in a vehicle while sitting
on the lap of another passenger.
-Holding a child in your arms is never a sub stitute for a child
restraint system .
- The stronge st p ers on could not hold the child with the force s
that e xist in an accident . The child will strike the interio r of the
v ehicle and can also be struck by the pa ssenger.
- The child and the passenger can also injure each other in an
accident.
• Never install rear-facing child safety seats or infant carriers on
the front pas senger seat. A child will be seriously injured and can
be killed when the passenger airbag inflates - e ven with an
Advanced Airbag Sy stem .
• 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 aga inst the bac krest, center arm rest, door o r roof.
• Always in stall rear -facing child safety seats or infant carriers
on the rear seat .
• Forward-facing child safety seats installed on th e front
passenger 's seat can interfere w ith the airbag when it inflates and
c ause seriou s injury to the child . Always install forward-facing
c hild safet y seats on the rear seat . .,

- 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 shoulde r.
- Always make sure that the shoulder portion of the safety belt never rests against or across the child's neck.
- Always make sure that the child can properly wear the lap
portion of the belt low across the thighs or pelvis and
never over the stomach or abdomen.
Children up to at least 8 years old (over 40 lbs. or 18 kg) are best
protected in child safety seats des igned for their age and we ight.
Experts say that the skeletal structure, particularly the pelvis, of
these ch ild ren is not fully developed, and they must not use the
veh icle safety belts w ithout a suitable ch ild restraint .
Children up to about 40 lbs (18 kg) are best protected in child safety
seats des igned for their age and weig ht. Expe rts say that the skeletal
structure, particularly the pelvis, of these children is not fully devel­
oped, and they must not use the vehicle safety bel ts witho ut a suit­
able child restraint .
It is usually best to put these chi ldren in appropriate booster seats.
Be sure the booster seat meets all applicable safety standards.
Booster seats raise the seating position of the child and reposition
both the lap and sho ulder parts of the safety bel t so that they pass
across the child's body in the right places. The routing of the belt over
the ch ild 's body is very impo rtant for the chi ld's p rotection, whether
or not a booster seat is used. Children age 12 and under must always
ride in the rea r seat.
Chi ld ren who are at least 4 ft. 9 in . (57 inches/1.45 meters) tall can
generally use the vehicle's three point lap and shoulder belts . Never
use the lap belt port ion of the vehicle 's safe ty belt alone to restra in
any child, regard less of how big the child is. Always remember that children do not have the pronounced pelvic structure requ
ired for the
proper func tion o f lap belt por tion of the vehicle's three poin t lap and
shoulder belts . The ch ild's safety absolutely requires that a lap belt
portio n of the safety be lt be fastened snugly and as low as possible
around the pelvis. Never let the lap belt portion of the safety belt
pass over the child's stomach or abdomen .
In a crash, airbags m ust inflate with in a blink of an eye and with
considerable force. In order to do its job, the airbag needs room to
inflate so tha t it w ill be the re to protect t he occ upant as the occupant
moves forward into the a irbag.
A vehicle occupant who is out of position and too close to the airbag gets in the way of an inflating a irbag. When a n occupant is too close,
he or she will be struck violently and will receive serious or possibly
even fata l injury.
In order for the airbag to offer protection, it is important that all
vehicle occupants, especia lly any ch ild ren, who must be in the front
seat because of exceptional circumstances, be properly restra ined
and as far away from the airbag as possib le .
By keeping room
between the child's body and the front of the passenger compart­
ment, the a irbag can inflate completely and provide supplemental
protection in certa in frontal collisions .
& WARNING
Not using a booste r s eat, using the boo st e r se at improperl y, incor ­

& WA RNING (c on tinued )
• Always make sure the lap belt portion of the three-point belt is
worn snug and pa sses as low a s pos sible across the ch ild 's pelvis .
Never let the belt pass over the soft abdomen.
• Failure to properly route safety belts over a child's body will
c ause severe injurie s in an accident or other emergen cy situation
:::> page 189.
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates .
• Never let a child stand or kneel on any seat, for e xample the
front seat.
• Ne ver let a child ride in the cargo area of your vehicle .
• Alway s remember that a child leaning forward, sitting side­
ways or out of position in any way during an accident can be struck
by a deploying airbag . This will result in seriou s personal injury or
death.
• If you must install a booster seat on the front pas senger seat
because of exceptional circumstances 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=>

Child Safety Ill
-------------------"'---
& WARNING (continued)
• 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 arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
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, immediately 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 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 .
Controls and equip­
ment Safety first Vehicle operation
-
Slowly pull the belt all the way out.
-Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down w ith 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.

Notice about data recorded by
vehicle control modu Les
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event. EDR's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped with
a number of e lectronic control modules for various vehicle systems
such as, for example, eng ine function, emission control, as well as for
the airbags and safety belts.
These electronic control modules also record vehicle-related data
during normal vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment .•
Electronic Stabilization Program

ESP is designed to he lp you maintain vehicle control in situations
where the car approaches the limits of "grip", especially when accel­
erating and cornering. ESP reduces the risk of skidding and improves
stability under all road conditions.

The system operates across the entire speed range in combination
w ith the ABS sys tem. If the A nti-L o ck Brak e System (A BS) mal fun c­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .

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 15 . •
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. 213 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. 213. 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=>&,.
