Important safety instructions for using child
safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of every
­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly~
page 243.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat , you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving~
page 248.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size. ..,

& 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.
• All vehicle occupants and especially children must 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 unrestrained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag.
• Commercially available child safety seats are required to
comply with U.S . Federal Motor Vehicle Safety Standard (FMVSSI
213 (in Canada CMVSS 2131.
-When buying a child restraint , select one that fits your child
and the vehicle.
- Only use child restraint systems that fully contact the flat
portion of the seat cushion . The child restraint must not tip or
lean to either side . Audi does not recommend using child safety
seats that rest on legs or tube-like frames. They do not provide
adequate contact with the seat .
- Always heed all legal requirements pertaining to the installa ­
tion and use of child safety seats and carefully follow the
instructions provided by the manufacturer of the seat you are
using .
• Never allow children under 57 inches (1 .5 meters) to wear a
normal safety belt. They must always be restrained by a proper
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 .
& WARNING (continued)
• Never let babies or older children ride in a vehicle while sitting
on the lap of another passenger.
- Holding a child in your arms is never a substitute for a child
restraint system .
- The strongest person could not hold the child with the forces
that exist in an accident. The child will strike the interior of the
vehicle and can also be struck by the passenger.
- The child and the passenger can also injure each another in
an accident.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat . A child will be seriously injured and can
be killed when the passenger 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 install rear -facing child safety seats or infant carriers on
the rear seat.
• Forward -facing child safety seats installed on the front
passenger's seat can interfere with the airbag when it inflates and
cause serious injury to the child . Always install forward -facing
child safety seats on the rear seat .
• If exceptional circumstances require the use of a forward ­
facing child restraint on the front passenger's seat , the child's
safety and well -being require that the following special precau­
tions be taken:
- Make sure the forward -facing seat has been designed and
certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
- Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier .

Booster seats
Properly used booster seats can help protect children
weighing between about 40 lbs . and 80 lbs. (18 kg and 36
kg) who are less than 4
ft. 9 in. tall.
Fig. 220 Rear seat:
chi ld properly
restrained in a booster
seat
The vehicle's safety belts a lone will not fit most children
until they are at least 4 ft. 9 in. tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children 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.
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 about 40 lbs (18 kg) are best protected in child safety
seats designed for their age and weight. Experts say that the skel ­
etal structure, particularly the pelvis, of these children is not fully
developed, and they should not use the vehicle safety belts
=> page 246 , fig. 220.
Children who weigh more than 40 lbs. (18 kg) may generally use the
available three point combination lap and shoulder belts when they
sit on an appropriate booster seat . 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 shoulder parts of the safety belt so that they pass
across the child's body in the right places. The routing of the belt
over the child's body is very important for the child's protection.
This applies whenever a chi ld uses the vehicle's safety belts, even
when the child is big enough to use them without a booster seat.
Children age 12 and under should
always ride in the rear seat .
Children should not ride in the front seat unless no other seating
position is available because crash statistics show that children are
better protected in the rear seat.
In a crash, airbags must inflate within a blink of an eye and with
considerable force. In order to do its job, the airbag needs room to
inflate so that it will be there to protect the occupant as the occu ­
pant moves forward into the airbag.
A vehicle occupant including a child who is out of position and too close to the airbag gets in the way of an inflating airbag . When an
occupant is too close, he or she will be struck violently and will
receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is important that all
vehic le occupants, especially any children, who must be in the front
seat in exceptional circumstances, be properly restrained and as far
away from the airbag as possible. By keeping room between the
child's or other occupant's body and the front of the passenger
compartment, the airbag can inflate fully and completely and
provide supplemental protection in certain frontal crashes . ..

___ C_h_ i_ ld _ S_ a_ f_ e_ t_y ____________________________________________ _
child is available. In these exceptional situations, the use of a lap
belt is better than permitting the child to remain total ly unre ­
strained . But remember: a lap belt cannot provide the same level of
protection as a proper child restraint or a three -point lap and
shoulder belt if the child is big enough . Also, using a lap belt for
younger child ren, who should be using a chi ld restraint, may violate
laws in your state or Province.
Never use a lap belt a lone to restrain a chi ld that weighs less than
about 80 lbs (36 kg) and who is less than 4'9" tall. A lways remembe r
that chi ldren do not have the pronounced pelvic structure required
for the proper function of lap belts. If a lap belt is only res traint
system available , then the child's safety absolutely requires that the
lap be lt be fastened snug ly and as low as possible around the pe lvis
let a lap belt pass over the chi ld's stomach or abdomen .
& WARNING
Using wrong child re straints or improperly in stalled child
restr aint s can cause serious personal injury or death in a cr ash .
• Failure to properly route safety belts over a child's body will
c au se severe injurie s in a crash . The lap belt portion of the three
point belt as well as any lap belt alone must alway s pass as low as
p os sible acros s the pelvis, n ever ov er the stoma ch or abdomen.
• An impr ope rly worn s afet y belt will not pr ovide the best prote c­
tion in a cra sh and may cau se seriou s personal injury . Alway s
make sure that children and other veh icle o ccupant s properl y
wear available r estraint system s. Carefully follow the in struction s
p ro vi ded by the manufa cturer s of child re straint s.•
Installing a child safety seat
Securing a child safety seat using a safety
belt
S afety belts for the rear seats and the fr ont passenger can
be locked with the c onvertible locking retr actor to pr op­
erly secure child safety seats.
The safety belts emergency locking retractors for the rear seats
safety be lts and for the front passenge r's seat safety belt have a
convertible 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 be lt and prevent the safety belt
webbing from loosen ing up dur ing normal driving. A child safety
seat can only b e properly instal led when the safety belt is locked so
t hat the child and chi ld safety seat w ill stay i n place .
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, al l children, especially those 12 years and
younger , shou ld always ride in the back seat proper ly restrained for
their age and size.
& WARNING
Improperly in stalled child safety seat s increa se the risk of serious
pe rsonal injury and death in a collision.
• Alway s ma ke sure that the safety belt retractor is locked when

& 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 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 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 secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a ch ild restraint in your vehicle. To
activate 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.

Intelligent technology
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 retrieva l or downloading of data stored
by EDR's that were insta lled 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 electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehicle-related data during norma l vehicle operation for diagnost ic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually 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 .•
Electron ic Stabilizat ion Program (ESP)
General =nformation
The ESP improves the vehicle stability.
(
Fi g. 232 C ente r
co nso le w it h ES P
swi tch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especia lly when
accelerating and cornering. ESP reduces the risk of skidding and
improves stabil ity under all road conditions .
T he system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP wil l also shut down .
How th e sys te m w ork s
The Anti -Lock Brake System (ABS) , Electronic Differential Lock (EDU
and the Anti-Slip Regulation System (ASR) are integrated in the e lec­
tronic stabi lization 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 vehic le about its vertical axis, vehicle acce leration in
the fore-and-aft and lateral directions, the brake pressure and the steering angle are al l measured .

The direction in which the driver wishes to travel is determined with
t he aid of the steering angle and vehicle speed and is continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehic le starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stab ilized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (rear tends to skid out
of the turn), the brakes are mainly app lied on the wheel that is on
the outside of the curve. In the case of a vehicle that is
understeering
(tendency to sl ide out of the curve), the brakes are applied at the
rear wheel that is on the inside of the curve . An acoustic signal indi­
cates when ESP brake application cuts in
~ & .
The system operates across the entire speed range in combination
with the ABS system
~ page 266 . If the Anti -Lock Brake System
(ABS) malfunctions, the ESP wi ll be out of action as well.
Ac tivat ing
When you turn on the eng ine, ESP will automatically be activated
and will perform a se lf -test . As soon as the test is comp leted, the
system is in norma l operating mode.
You can activate a deactivated ESP or deactivated ESP/ASR if required by pressing the~
page 262, fig. 232 button . When they are
activated, the message
E S P/AS R on appears briefly in the display.
D eactiv ating
The ESP should normally be activated al l the time . If necessary, you
can deactivate An ti- Slip Regulation (ASR) or the E lectronic Stabiliza ­
tion Program (ESP) by pressing the button~
page 262, fig. 232 .
• Dea ct iv at ing A SR: Tap the button . In certain exceptional situa ­
tions (e.g. driving with t ire chains) , the Anti-Sl ip Regulation (ASR)
can be deactivated ~

Electronic differential tock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
Gener al note s
The electronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
almost no grip . Without EDL, this would be difficult, if not impos ­
sib le .
How th e sys te m wo rk s
The EDL operates automatical ly . It monitors the rotational speed of
the drive wheels on an axle with the he lp of the ABS sensors
~ page 266 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power
to the other drive wheel or whee ls (a ll -whee l drive) . Th is is done up
to a speed of about 60 mph ( 100 km/h). Noises from the brake
system signal that wheel spin is being control led .
Dr iving off
When driving off , always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
Iii>

with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo ­
rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 21. •
Ant"-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the engine power to match the amount of grip available from the road
surface.
How the system works
ASR
performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 266, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will 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 262, fig. 232 button . When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front-wheel drive a deactivated ASR automatically re-activates
itself at a speed of 40 mph (70 km/h) .
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 262, fig. 232. With the ASR deactivated,
the ESP check light comes on, see=>
page 18. The message ASR off
appears in the display as well. On vehicles with front-wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons . Vehicles with all -wheel drive: the ASR can be deactivated
at any speed .
The ASR should normally be activated all 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 .
