-Have the airbag system inspected by
your authorized Audi dealer immediate­
ly.
(D Tips
The child seats listed in categories A to C have been statically tested by Audi only for
the Advanced Airbag function.
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 safe­
ty of everybody in the vehicle, especially chil­
dren:
~ Always use the right child safety seat for
each child and always use it properly
¢ page 179.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly 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 184.
~ 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) .
~ Secure unused safety belts on the rear seat
¢page 179.
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.
_& WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­ stalling a child restraint increases the risk
of serious personal injury and death.
-
Child Safety 177
- All vehicle occupants and especially chil­
dren must always be restrained properly
whenever riding in a vehicle.
- An unrestrained or improperly restrain­
ed child can be injured or killed by be­
ing thrown against the inside of the ve­
hicle or by being ejected from it during
a sudden maneuver or impact.
- An unrestrained or improperly restrain­
ed 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 (FMVSS)
213 (in Canada CMVSS 213).
- 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 per­
taining to the installation and use of
child safety seats and carefully follow
the instructions provided by the manu­
facturer of the seat you are using.
- Never allow children under 57 inches
(1.45 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 abdo­
men and neck areas during sudden brak­
ing maneuvers or accidents.
- Never let more than one child occupy a
child safety seat.
- Never let babies or older children ride in
a vehicle while sitting on the lap of an­
other 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

F ig. 171 Schematic overview: keep unused safety belts
away from chi ldren in child safety seats. @-outer rear
safety belt,
@-center rear safety belt*
If a child safety seat is used on the rear bench,
espec ially with LATCH universal lower ancho­
rages, the unused safety belts
mu st be se­
cured so that the ch ild in the ch ild restra int
cannot reach them
Q ,&. .
- Gu ide the safety belt webbings @and @*
behind the head restraint of the seat whe re
the ch ild restrai nt is installed
Q fig . 171.
When doing so, do not engage the converti­
ble locking retractor! Yo u should not hear a
"clicking" sound when winding up the safety
belt.
- Let the belt retractor wind up the safety be lt
webbing.
A WARNING
A child in a child safety seat installed with
the LATCH lower anchorages or w ith the
standard safety belt or a child in a booster
seat on the rear seat could play with un­
used rear seat safety belts and become en­
tangled. This could ca use the child serious
personal i nju ry and even death.
- Always secure un used rear seat safety
belts out of reach of chi ld ren in ch ild
sea ts such as by p rope rly routing them
around the head res traint of the seat
whe re the child restraint is installed.
- Never act ivate the convertib le loc king re­
t ractor when rout ing the safety belts
around the head res traints .
- Never le t anyone sit at the center rear

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or
9 kg need special rearward-fac­
ing child restraints that support the back,
neck and head in a crash .
Fig. 172 Schemat ic overv iew: rearward -facing infant
seat, properly installed on the rear seat
~ When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertible locki ng retractor on the
safety belt to preven t the child safe ty seat
from mov ing
Qpage 184 or install the seat
using the LATCH attachments .
~ Push the child safety seat down with you r
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).
~ Secure unused safety belts on the rear seat
Qpage 179.
Infants up to about one year (20 lbs. or 9 kg)
are best protected in special infant car riers
and child safety seats designed for their age
group. Many experts be lieve that infants and
small chi ld ren shou ld r ide o nly in special re­
str aints in wh ic h t he child faces the back of
the ve hicle. These infant sea ts suppo rt the ba­
by's back, neck and head in a crash ¢

~ Secure unused safety belts on the rear seat
¢page 179.
Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight. Ex­
perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully
developed, and they must not use the vehicle
safety belts without a suitable child restraint.
It is usually best to put these children in ap­
propriate 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 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, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Children who are at least 4
ft . 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle's three point lap and shoulder belts .
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regard­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point
lap and shoulder belts. The child's safety ab­
solutely requires that a lap belt portion of the
safety belt 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 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 occupant moves forward into the air­
bag.
A vehicle occupant 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
Child Safety 183
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible . By keeping room between
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 .
_&. 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:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per body . It must never lie across the
throat or neck . The lap belt must lie
across the pelvis and never across the
stomach or abdomen. Make sure that the
belt lies flat and snug. Pull on the belt to
tighten if necessary.
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation
¢page 138.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat.
- For adjustable head restraints: adjust or remove the rear seat head restraint if it
is difficult to install the child seat with
the head restraint in place¢
page 57. In­
stall the head restraint again immediate­
ly once the child seat is removed. Driving

Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the conver tible
locking retractor to properly secure child
safety seats.
The safety belts emergency locking retractors
f or the rear seats safe ty belts and for the fron
t passenger's seat safety be lt have a con ­
vertib le locking ret ractor for child restraints .
The safety belt m ust be locked so that be lt
webbing cannot unreel. The retractor can be activated to lock the safety belt and prevent
the safety belt webbing from looseni ng up
duri ng normal dr iv ing. A child safety seat can
o nl y be prope rly insta lled when the safety be lt
i s lo cked so that t he ch ild and child safety
sea t w ill stay in place .
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all

186 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.
- 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 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 se at down with you r
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 retracto r. 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
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.
- 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.

distance detected to the veh icle a head is too
smal l.
Anti -slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the d rive power to the other wheels.
This f unct ion is not availab le at h igher speeds.
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on aga in au­
tomatically when conditions have returned to norma l.
St eering recommendat ion
The ESC helps to stabilize the vehicle by
cha nging the steering to rque.
In vehicles with dynam ic steering*, ESC also
helps to stabilize the steering in critical s itua­
tions .
Select ive w heel to rque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
This a llows more prec ise driving in curves. The
applicable system may not activate when d riv­
ing i n wet or snowy conditions.
.&_ WARNING
- T he ESC and its integrated systems can­
not overcome the limits posed by natural physical laws
. This is especially impor­
tant on slippery or wet roads. If the sys­ tems beg in acting to stabilize your vehi­
cle, you should immediately change your
speed to match the road and traffic con­
d itions . Do not let the increased safety
p rovided by these systems tempt you to
take risks. Do ing so will increase the ri sk
of a loss of veh icle cont ro l, collision and
serio us personal inj uries.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast , especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys­
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin even w ith
these assistance systems that c annot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped wi th iden ti­
cal tires. D ifferen t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are workin g.
-If the ind icator light DJ or Ea (USA

The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immediate ly to have the
malfunction corrected . The co lor of the indica­
tor light depend s on the veh icle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler deployed can impair handling char­

-Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (140 km/h). If th e rear spoiler
wa rning/ind icator light in the instru­
ment cluster comes on, the rear spoiler
may not have deployed.
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
dep loyed. Have the spoiler inspected as
soon as possible by an authorized A udi
dealer or qualified workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoiler can
cause crushing injuries. -
Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.
(D Note
- Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
- To prevent damage to the rear spoiler do
not lean or place anything on it .
- Only operate the rear spoiler man ually
when the rear lid is closed and the rear
spoiler moving parts are not blocked.
Otherw ise, damage co uld occur.
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compartment must
always be free of ice, snow, leaves or other
debris.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
r:::;, ,& . On
vehicles that are either dr iven mostly in stop­
and-go city traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes , you sho uld use the braking
effect o f 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 inuous ly. Pump the brakes at inter­
vals.

than is being generated and ensures an opti­
mal state of charge for the battery.
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
li mited.
- If starting ability is threatened, the indi­
cator light (•) appears¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant e lectrica l energy is re­
quired, but only a little is generated.
It is also
crit ical if the engine is not running and electri­
cal components are turned on. In this in­
stance energy is being consumed but none is be ing generated .
It is in precisely these situations that you wi ll
notice energy management actively regulat­
ing the distribution of energy.
Vehicle stands for an e xtended period
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched
off.
This reduces energy consumption and main­
tains starting capab ility over a longer period.
Some of the conven ience functions may not
ope rate, such as the inter ior lights or the
power seat adjustment. The conven ience
f u nctions w ill be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned
off or use other MMI func­
tions, the battery is being discha rged .
If starting capability is jeopardized due to en­
ergy consumpt ion, the following warning ap­
pears in t he MMI display:
Please start the engine soon or the system
will be turned off.
The wa rn ing ind icates that the system will be
turned
off automatically after 3 minutes. If
you wish to continue using the functions, yo u
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicl e is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and t he battery's state of
charge is not opt imal.
To bring the energy ba lance back into equili­
brium , consumers which require especially
large amounts of energy are temporari ly cut
back or switched
off. Heating systems in par­
t icular require 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 temporarily cut back or sw itched
off. These systems w ill be available again as
soon as the energy balance has been 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 addi tional energy requi red is gener­
ated and the batt ery is charged.
