It is usually best to put these children 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 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
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-
Child Safety 161
pletely and provide supplemental protection
in certain frontal collisions.
A 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 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 123.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat .
- Children on the front seat of any car, even with Advanced Airbags, can be seri­
ously injured or even killed when an air­
bag inflates .
- Never let a child stand or kneel on any
seat .
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning
forward, sitting sideways or out of posi­
tion in any way during an accident can be
struck by a deploying airbag. This will re­
sult in serious personal injury or death .
- If you must install a booster seat on the
front passenger seat because of excep­
tional circumstances the

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
pas senger 's seat can be locked with the con­
vertible locking retractor to properly secure
child safety seats.
The safe ty belts eme rgency lock ing re tractors
fo r the re ar seats safe ty belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r fo r child restraints.
The safety belt must be locked so that belt
webbing cannot unree l. The retractor can be
activated to lock the safety be lt and prevent
the safety belt webbing from loosening up
during normal driving . A child safety seat can
only be properly installed when the safety belt
i s locked so that the child and child safety
seat will stay in place.
A lways remember: Even thoug h your veh icle is
eq uipped w it h an Advanced A irbag system, all
ch ildren , espec ia lly those 12 yea rs and yo ung­
e r, should always ride in the ba ck seat proper­
l y res traine d for thei r age and weig ht.
_& WARNING
Imprope rly insta lled child sa fe ty seats in ­
crease the risk of ser ious personal inju ry
and death in a collision. -
Always make sure that the safety belt re­
tractor is locked when insta lling a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place dur ing no rma l dr iving o r in a
crash .
- Always buckle the child safety seat firmly in place even if a ch ild is not sitt ing in it .
A loose child safety seat can fly aroun d
du ring a s udden sto p or in a colli sion.
- I f the backrest is not securely la tched,
the child and the child restraint will be
throw n forward toge ther with t he ba ck­
rest and will strike par ts of the vehicle
interior. The child can be se riously in ­
jured or killed.
- Never inst all rearward-facing child safety
seats or infant ca rr iers on the front pas­
senger seat . A child will be serious ly in­
jured and can be killed when the passen­
ger airbag i nflates.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the back rest , center

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
<;hild.
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can cause injury in a crash.
_&. 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
Child Safety 163
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
al circumstances.
-A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­ bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­
ploy 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, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer. •

Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In 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 switch on aga in a u­
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 steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l 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 selective ly as needed.
This a llows mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
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 p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance 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
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.

Braking
What affects braking efficiency?
New brake pad s
Du ring the first 2 50 miles (400 k m), new
b ra ke pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
You can compensate for this slightly reduced br aking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
b reak-in per iod.
Operating conditions and d riving h abits
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat­
ing conditions and dr iv ing habits ¢.&. . On
vehicles that are e ithe r dr iven mostly in stop­
and-go city traffic o r are driven ha rd, the
b rake pads should be checked by you r aut hor­
iz ed A udi de aler more often than specified in
the
Warrant y & Maintenan ce booklet . Fail ure
to have your b ra ke pads inspected can resu lt
in red uced brake performance.
On steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the eng ine. Th is w ay, you preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
N oises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature a nd h umidity.
Due to the na ture of the mate rials used i n ce­
ramic brake rotors*, noises may become more
apparent at low speeds.
Effect of water and road salt
I n ce rtain situat ions, for exampl e after d riving
throug h wate r, in heavy ra in, after overn igh t
conde nsation or afte r washi ng your c ar, the
b ra ki ng effect can be reduced by moisture or
ice on the bra ke rotors and b rake pads. The brakes must be dr
ied first with a few careful
brake applications .
At highe r speeds and with the winds hield wip­
ers t urned on, the b ra ke pads press against
the b rake roto rs fo r a short amount o f time .
This occurs at regular intervals without the drive r not icing and p rov ides for better brake
response time under wet conditions.
The effectiveness of the brakes can be red uced
whe n the vehicle is driven on a sa lt -covered
road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap­
plicat ions of the bra ke
¢ .&. .
D ue to the ir s urface characteristics, ceramic
brake rotors* absorb moisture in such condi­
tions . T his can cause a temporary reduction in
braking force compared to dry brakes . You can
compensate for th is by pressi ng the brake
p eda l harde r.
Corrosion
There may be a tende ncy for dirt to build up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regu larly or
only for short trips w it h litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros io n has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed ¢.&. .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c::> .&. .
Low brake fluid level
Malfunctions can occur in the brake system if
t h e brake fluid level is too low. The brake flu id
level is monitored electro nically .

With th e engine turn ed off
If yo u listen to the radio, for example, with
the engine turned off or use other MMI fu nc­
tions, the battery is being discharged .
I f sta rting capabi lity is jeopa rdized due to en ­
e rgy consumpt ion, the fo llowing warning ap­
pears in the MMI display:
Please start the eng ine soon or th e syste m
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes. If
you wish to con tinue us ing t he functions, you
have to s tart the engi ne.
With the engine running
A lthough electrical energy is generated when
the veh icle is be ing dr iven, the battery can be­
come discharged . T his happens most ly when
little energy is be ing generated a nd a great
deal consumed and the battery 's state o f
charge is no t optima l.
To br ing the energy balance back into equili­
b rium, consumers which require especially
l arge amo unts of energy are tempo rari ly cut
back or switched off. Heating sys tems in par­
ticular require a great dea l of energy . If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy ba lance has been restored.
You will a lso notice that engine idle speed has
been increased slightly. This is norma l and not
a cause for concern . By increasing engine idle
speed the add itiona l energy required is gener­
ated and the batte ry is charged .
