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 re­
strained 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 be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­
hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater risk of injury or death
through contact with 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 cush­
ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide 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 in­
structions provided by the manufacturer
of the seat you are using.
Child safety
- 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 abdomen and
neck areas during sudden braking maneu­
vers 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 another passenger.
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.
- The child and the passenger can also in­
jure each other 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 in­
flates -even with an Advanced Airbag Sys­
tem.
- 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 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 for­
ward-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 precautions be taken: ..,.
163

Child safety
-Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat w ith a
passenger front and side airbag .
- Always carefully follow the manufacturer 's
instructions provided with the child safety
seat o r carrier .
- Always move the front passenger seat into
the rearmost position of the passenger
seat's fore a nd aft adjustment range, and
as far away from the airbag as possible be­
fore insta lling the child restraint.
- Always make sure that nothing prevents
the front passenge r's seat from be ing
moved to the rearmost posit ion in its fore
and aft adjustment range.
- Always make sure that the back rest is in
the upr ight position .
- Never place or use any e lectr ica l device
(such as a laptop , CD player , e lectron ic
g ames device, power inve rter or sea t heat­
er for ch ild seats) on the front passenger
seat if the device is connected to the 12 -
volt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any chi ld restraint sys­
tem on th is seat .
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liqu ids on the front passenger seat
cushion .
- Never place objects on the seat (such as a laptop, CD p layer, electron ic games de­
vice, power inverter or seat heater for
child seats). These may influence the elec ­
trical capacitance measured by the capaci­ tive passenge r detection system and can
a lso fly around in an accident and cause
serio us personal in jury.
- Always bu ckle the child safety seat firmly in
place even if a child is not s itting in it. A
loose child safety seat can fly around during
a sudden stop or in a collisio n.
- Always re ad a nd heed all WARN INGS when­
ever using a child restrained in a vehicle is
being used

A WARNING
To reduce the risk of serious injury, make sure
that the
PASSENGER AIR BAG OFF light
comes on and stays on whenever a ch ild re ­
stra int is installed on the front passenger seat
and the ign ition is switched on .
- Take the child restra int off the front passen ­
ge r seat and install it prope rly at one of the
rear seat positions if the

If a child safety seat is used on the rear bench,
especially with LATCH universal lower anchorag ­
es, the unused safety belts
must be sec ured so
that the c hild in the child rest raint cannot reach
them
c::> _&. .
- Guide the safety belt webbing @ behind the
head rest raint of the seat where the child re­
st raint is installed

do not engage the convert ib le loc king re trac·
to r! Yo u should not he ar a "cl icking " so und
when winding up the safety bel t.
- Let the belt retracto r wind up the safety belt
webbing.

In o rder for the airbag to offer protection, it is
important that all vehicle occupants, especia lly
any children, who must be in the front seat be­
cause 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 passenger compart­
ment, the airbag can inflate comp letely and pro­
vide supp lemental protect ion in certain frontal
coll is ions.
A WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly insta lling a boos ­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situat ion. To help reduce the risk of se­
r ious personal injury and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body .
It must neve r lie across the throat or
neck. The lap belt must lie across the pelv is
and never across the stomac h or abdomen.
Make sure tha t the belt lies fla t and sn ug.
Pull on the belt to tighten if necessary.
- Failure to p roperly route safety belts over a
child 's body will cause severe injuries in an
accident or other emergency situation
¢ page 127.
-The rear side of the child sa fety seat should
be pos itioned as close as possible to the
backrest on the vehicle seat .
- For adjustable head restraints: adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restra int in place ¢
page 56. Install the
head restraint again immediately once the
child seat is removed. Driving w ithout head
restra ints or w ith head restraints that are
not properly adjusted increases the risk of
serious o r fa ta l neck injury d ramatically.
- Children on the front seat of any car, even
with Advanced Ai rbags, can be se riously in­
jured or even killed when a n ai rbag inflates.
- Never let a child stand or knee l on any seat,
for example the front seat.
-
Ch ild safety
-Never let a chi ld ride in the cargo area of
your veh icle.
- Always remember that a chi ld leaning for­
ward, sitting sideways or out of position in any way du ring an accident can be struck by
a dep loying airbag. Th is w ill result in serious
personal injury or death .
- If you must install a booster seat on the
front passenger seat because of exceptiona l
circumstances the

seriously injure or even kill the child.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier .
- After checking to make sure that the child
restraint is properly installed, make certain
that the child restraint is correctly recog­ nized by the capacitive passenger detection
system in the front passenger seat and that
the
PASSENGER AIR BAG OFF light signals
the correct front passenger frontal airbag
status.
.&_ WARNING
Forward-facing child restraints:
- Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward-facing child restraint
up, against or very near the instrument pan-

Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.
.,. Depress the spring catch on the hook and re­
leas e it from the anchorage.
(D Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently stretched around the tether strap . This applies especially to
leather seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc­
tions carefully to determine how to properly in­
stall the tether.
A WARNING
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, or
door.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear

Electronic Stabilization
Control (ESC)
Description
E SC helps to imp rove ro ad hold ing and vehicle
dynamics to help reduce the probab ility of skid­
d ing and loss of veh icle control. It works only
when the engine is runn ing . ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicl e is begin ning to spin (yaw) o ut of contro l
and h elps you to ge t the veh icle b ack u nde r con ­
trol by se lectively bra king the wheels, and/or re­
ducing engine powe r and providing steering as­
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI in the in­
strument cluster blinks when ESC is tak ing action
t o he lp you contro l the vehicle.
ESC has lim itations. It is important to remembe r
that ESC cannot overcome the laws o f physics. It
will not a lways be able to help out under all con­
d itions you may come up aga inst . For example,
ESC may not always be ab le to help you master
situations where there is a sudde n change in the
coeff ic ie nt of fr iction of the road surface. W hen
there is a se ction of dry roa d that is sudde nly cov­
e red with w ater, slush o r sn ow , ESC c annot pe r­
form the same way i t wou ld on the dry s urface. If
the vehicle hydrop lanes (rides on a cushion of wa­
ter instead of t he road su rface), ESC w ill not be
ab le to he lp you stee r the veh icle because contact
with the pavement has been inte rru pted and the
ve hicle cannot be b raked or steered . Dur ing fast
cor nering, part icu la rly on w inding roads, ESC
can not always deal as effect ive ly w it h difficult
d riving situat ions than a t lowe r speeds .
Always ad just yo ur speed and driving sty le to
road, traffic and weath er cond itions . ESC canno t
over ride the vehicle's phys ical lim its, increase the
ava ilab le traction, o r keep a ve hicle on t he road if
roa d depa rture is a re su lt of driver in attention .
I nstead, ESC imp roves the possibili ty of keep ing
180
t h e veh icle unde r contro l and on t he road d uring
extreme mane uvers by using the driver's steer ing
i nputs to help keep the veh icle go ing in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rovide any assistance, you may not exper i­
ence the be nefits of ESC.
ESC is switc hed on all the time. In certa in s itua­
tions when you need less tract ion, you can sw itch
off ASR by press ing the button
[g] c:> page 181,
fig . 175 . Be sure to switc h ASR on aga in whe n
you no longer nee d less tract ion.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
A BS prevents the w heels from locking w hen bra k­
i ng . The veh icle can still be steered even dur ing
hard braking. App ly steady p ressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake peda l ind icates that the system is act ing to
stab ilize the veh icle.
Brake a ssist system
The brake assist system can decrease b raking dis­
tance. It increases b raking powe r whe n the dr iver
presses the b rake peda l quickly in emergency sit­
uat ions. You must press a nd hold the brake peda l
u nt il the dange rous situation is over . In vehicles
with adaptive cruise co ntrol*, the brake ass ist
syste m is more se nsitive if the distance detected
t o t he veh icle ah ead is too sm all. On vehicle s wi th
a ctiv ate d a nd fun ctioni ng nigh t vis ion assi st*, the
brake assis t sys tem can respond more sensit ively
i f there is a warning .
Anti-slip regulation (ASR )
ASR reduces e ngine powe r whe n the d rive whee ls
begin s pin nin g and ad apts the force to the ro ad
con ditions. This m akes i t easier to s tar t, a cce ler ­
ate and drive up incl ines .
Electronic differential lock (EDL)
E DL applies t he b rakes to a whee l th at s tarts
sp inning a nd transfers the dr ive power to the
othe r drivi ng whee ls . This fu nction is n ot a vail a-
b le at hig he r sp eeds . .,..

In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over­
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi ­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa ­
tions.
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves. The front wheel on the inside of
the curve or both wheels on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the risk of sliding and of other
coll isions after an accident.
If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not function ing .
Switching on /off
Intelligent Technology
A WARNING
-- The ESC and its integrated systems cannot
overcome the limits posed by natural physi­
cal laws. This is especia lly important on slip­
pery or wet roads. If the systems begin act­
ing to stabilize your vehicle, you should im­
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking r isks. This cou ld increase your risk of
a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The dr ive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
i n crease the risk of a collision .
(j) Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
£SC turns on automatically when you start the engine.
Fig. 175 Center console: OFF~ button
The ESC is designed to function in levels. Depend­
ing on the level that is se lected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de­
pending on the level.
The following examples are unusual situations
where it may make sense to switch sport mode on in order to allow the wheels to spin:

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢&, . The b reak-in pe­
riod can be considerably longe r fo r vehicles with
182
ceramic brake rotors* . You can compensate for
this slightly reduced braking power by pushing harder on the brake pedal. Avoid heavy braking
l oads during the break-in per iod.
Op erating c ondition s and dri ving habits
The brak es on today 's automobiles are still sub ­
ject to wear, depending large ly on operating con­
dit ions and driving habits ¢&, . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads shou ld be
checked by your authorized Audi dealer more of­
ten than specified in the
Warr ant y & Maint e­
nance booklet .
Failure to have your brake pads
i nspected ca n result in red uced b rake perfo rm­
ance.
On steep slopes, you should use the brak ing ef ­
fect of the engine . Th is way, you prevent unnec­
essa ry wea r on the brake system. If you must use
you r brakes, do not ho ld the brakes down contin­
u ous ly. P ump the brakes at intervals.
Operating noi se
Noises may occur when brak ing depending on the
speed, braking force and outside conditions such as temperature and h umid ity.
Due to the nature of the mater ials used in ceram­
i c brake rotors*, no ises may become more appa-
rent at low speeds. ..,.

Effect of wat er and road salt
In ce rtain situations, for example after driving
through water, in heavy rain, afte r ove rnight con ­
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first w ith a few careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. Th is occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coat ing from brake discs
and pads with a few cautious applications of the b rake ¢_&. .
Due to their surface character istics, ceramic
brake roto rs* absorb mo isture in such condit ions.
This can cause a temporary reduc tion in braking
force compared to dry brakes. You can compe n­
sate fo r th is by press ing the b rake peda l harder.
Corrosion
There may be a tende ncy for d irt to bu ild up on
the brake pads and corros ion to form on the discs
if the car is not dr iven regularly or only fo r sho rt
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is adv isable to
clean off the pads and discs by brak ing firmly a
few t imes from a mode rately h igh speed ¢,& .
Faults in the brake system
If you should notice a sudden increase in brake
pedal travel, then one of the two brake c ircuits
may have failed
¢ ,& .
Low brake fluid le vel
Malfunct ions can occur in the brake system if the
brake fl uid level is too low. The brake fluid level
is monitored electronically .
Intelligent Technology
Brake booster
The brake boos ter works w ith v acuum press ure
which is crea ted on ly when the engine is running

Brake lining wear status
Brake lining wea r may be chec ked by visua l in­
spe ct ion of the condition of the brake pads
t hr ough the openings in t he wheel. If necessary,
the wheel may be removed for this inspection

_8 WARNING "'----
-New b rake pads don't have the best stop­
p ing power and must be "broken-in" d uring
the initial 250 miles (400 km). The b reak-in
period can be considerably longer for
veh icles with ceramic brake roto rs*. You can
compensate for this by pressing the brake
pedal mo re firmly. This also applies late r
when new p ads are inst alled.
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit io ns pe rmit. O ther ro ad
users m ust no t be put at r is k - you may
cause an accident!
- Before descending a steep g rade, reduce
speed and shift transmission into a lower
gear o r lower driving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This cou ld cause t he b rakes to get
hot and dimin ish braking effic iency.
- Do not " ride the brakes" by rest ing your foot
on the pedal when you do not intend to brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance .
- Unde r certain climatic and ope rating condi­
tions such as passing t hrough water, d riving
i n heavy rain o r afte r wash ing the veh icle,
the effectiveness of the brakes ca n be re­
duce d. In winter, ice can accum ulate on the
b rake pads, lin ings, discs and dr ums. Care­
fu lly apply brakes for a test. Brakes will d ry
an d ice coatings will be cleaned off after a
few ca refu l brake applications.
