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 171.
~ 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 176.
~ 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 171.
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 169
- 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

Secure unused safety belts on the rear
seat
F ig. 169 Schematic overview: keep unused safety belts
away from chi ldren in child safety seats. @-outer rear
safety belt
If a child safety seat is used o n 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 ¢
,&..
- Gu ide the safety belt webbing @behind the
head restraint of the seat where the child re­
stra int is ins ta ll ed
¢ fig. 169. When do ing
so, do not engage the conve rtible locking re­
tractor! You should not hear a "clicking''
sound when winding up the safety be lt.
- Let the belt re tractor wind up the s afety be lt
webbing.
_& WARNING
A child in a child safety seat installed with
the LATCH lower anchorages or with the
standard safety belt or a child in a booster
seat on the rear seat could play with u n­ used rear seat safety belts and become en­
tangled. This could cause the child serious
pe rsonal in ju ry and even deat h.
-Always secure u nused rear seat safety
belts out of reach of ch ild ren in ch ild
sea ts such as by properly routing them
around the head res traint of the sea t
whe re the child res traint is installed.
- Never act ivate the convertib le loc king re­
tra ctor when rout ing the safety belts
around the head res traints.

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 . 170 Schematic overv iew: rearward-fac ing infant
seat, properly installed on t he rear seat
.. When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertib le locki ng retractor on the
safety belt to p revent the child safety seat
from moving¢
page 176 or install the seat
using the LATCH attachmen ts .
.. Push the chi ld 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 171.
Infants up to about one year (20 lbs. or 9 kg)
are best protected in spec ial infant carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small ch ildren shou ld r ide on ly in special re­
stra in ts in wh ich the child fa ces the back of
the vehi cle. These infant sea ts support the ba­
by 's back, neck and head in a crash ¢
fig. 170 .
The airbag on the passenger side makes the
front seat a potentia lly dange rous place for a
ch ild to ride. The front seat is not the safest
place for a child in a fo rward-facing child seat.
It is a very dangerous place for an infant or a
larger child in a rearward-facing seat. .,._

~ Secure unused safety belts on the rear seat
c::> page 171 .
Children up to at leas t 8 years old (over 40 lbs
or 18 kg) are best protected in chi ld safety
seats designed for their age and weight . Ex­
perts say that the ske letal structure, particu­
larly the pelvis, of these chi ldren is not fu lly
developed, and they must not use the vehicle
safety belts without a su itable 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
chi ld and reposition both the lap and shou lder
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 ch ild's protection, whether
or not a booste r seat is used . Children age 12
and under must always ride in the rear seat.
C hi ldren who are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle's three po int lap and shoulder belts .
Never use the lap belt portion of the veh icle's
safety be lt a lone to restrain any child, regard­
l ess of how b ig the child is. Always remembe r
that children do not have the pronounced pe l­
vic structure required for the proper function
of lap belt portion of the ve hicle's three point
l ap and shoulder be lts. The child's safety ab­
solutely requ ires that a lap be lt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
be lt portion of the safety belt pass over the
child's stomach or abdomen.
In a cras h, airbags must i nflate within a blink
of an eye and with cons iderable force. In orde r
to do i ts job, the airbag needs room to inflate
so that it will be there to p rotect the o ccupant
as the occupant moves forward into the air­
bag.
A vehicle occupant who is out of pos ition and
too close to the airbag gets i n the way of an
inflat ing a irbag. When an occupant is too
close, he or she w ill be str uck violen tly and
Child Sa fet y 175
will receive se rious or possib ly even fatal in ­
jury .
In orde r fo r the airbag to offer pro te ction, i t is
important tha t all veh icle occupants, espec ial­
ly any children, who m ust be in the front seat
because of exceptiona l 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 a irbag can inflate com ­
pletely and provide supplemental protection
in certain frontal collisions .
_&. WARNING
Not using a booste r seat, using the boos­
ter se at imp roperly, incorrectly installing a
boos ter sea t or using the vehicle safety
belt imp roperly increases the risk of seri­
ous persona l injury and death in a collision
or other emergency situat ion. To he lp re­
duce the risk of serious personal injury
and/or death:
- The shou lder belt must lie as close to the
center of the ch ild's collar bone as possi­
ble and must lie f lat 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 neve r across the
s tom ach o r abd omen. Make sure that the
be lt lies flat and sn ug. Pull on the bel t to
tighten if necessary.
- Failure to p roperly ro ute safety belts
over a child's body will ca use seve re inj u­
ries in an accident or othe r emergency
situation
c::> page 130 .
-The rear side o f the child sa fety seat
should be pos itioned as close as possib le
to the backrest on the vehicle seat.
- For adj ustab le head restraints: adjust or

-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 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 165. Special
precautions apply when installing a child
safety seat on the front passenger seat

seat -some important things to know.
_& 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 151, 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.
Child Safety 177
- After checking to make sure that the
child restraint is properly installed, make
certain that the child restraint is correct­ ly recognized by the capacitive passenger
detection system in the front passenger
seat and that the
PASSENGER AIR BAG
OFF
light signals the correct front pas­
senger frontal airbag status .
_& 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
with 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.
_& 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-

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv­
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly 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
ditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Do ing so will increase the risk
of a loss of veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los­
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry 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 assistan ce sys tems that cannot al­
ways he lp to re duce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi­
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht

Indicator lights
I)/. Rear spoiler: system malfunction!
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 immed iately to have the
malfunction corrected . The co lor of the indica­
tor light depends on the veh icle speed.
A WARNING
-Driving at higher speeds without the rear
spoiler deployed can impair handling char­
acteristics, making the vehicle harder to
control.
-Always make sure that the spo iler is de­
p loyed when driving at speeds over
85 mph (140 km/h) . If the rear spoiler
warn ing/ indicator 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
deployed. Have the spoiler inspected as
soon as possible by an authorized Audi
dealer or qualified workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoi ler 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 spo iler do
not lean or place anything on it.
- Only operate the rear spoiler manually
when the rear lid is closed and the rear
spoiler moving parts are not blocked. Otherwise, damage cou ld 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.

Dynamic en erg y managem ent
While the vehicle is being dr iven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It reg ulates cons umption, so
that more electrical energy is not being used
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.

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 co ld time
of year. Abu ndant e lectr ical energy is re- quired, but on
ly a little is generated .
It is also
critica l if the engine is not r unning and electri­
ca l components are turned on. In this in­
stance energy is be ing consumed but none is
being generated .
It is in precise ly these situations that you will
notice energy management active ly regu lat­
ing the d istribution of energy.
V ehicle stand s for an e xtended period
If you do no t drive your vehicle over a period
of several days or weeks, e lectrica l compo ­
nents a re g radually cut back or switched off .
This reduces energy consumption and main­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
power seat adjustme nt. The convenience
funct ions wi ll be available again when you
switch on the ignition and sta rt the eng ine .
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func­
t io ns, the battery is be ing discharged .
If starting capability is jeopardized d ue to en­
ergy consumption, the following warning ap­
pears in the MMI d isplay:
Please sta rt the engine soon o r the system
will be turned off .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, yo u
have to start the eng ine.
With the eng ine running
Although e lectrical energy is generated when
t h e vehicle is being driven, the battery can be­
come discharged . This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
c h arge is not opt imal.
To bring the energy ba lance back into equili ­
brium, consumers which requ ire espec ially
large amounts of energy are temporar ily cut
back or sw itched off . Heat ing systems in .,.
