backrest, door or roo f. Have the airbag
system inspected immediately by your
Audi dealer.
@ Tips
The ch ild seats listed in categories A to C
have been statica lly tested by Aud i 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 dr iver, you are respons ible for the safe­
ty of everybody in the veh icle, especially ch il­
dren:
.,. Always use the right ch ild safety seat for
each child and always use it properly
~page 134.
.,. Always carefully fo llow the child safety seat
manufac turer's inst ruct ions on how to ro ute
the sa fety 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 mov ing
r=> page 137 .
.,. Push the ch ild safety seat down with you r
full weight to get the safety be lt really tight
s o that t he seat canno t move fo rward o r
sideways more th an one inch
(2.5 cm).
Always remember : Even though you r vehicle is
equipped with an Advanced Airbag system, a
c hi ld shou ld always ride i n the seat properly
r estrained for its age and s ize.
_& WARNING ,..___
Not using a child safety seat, using the
wrong child safety seat o r improperly in­
stalling a ch ild restra int increases the risk
of ser ious personal in jury and death.
- All vehicle occupants and especially chil­
dren must always be restrained properly
whenever rid ing i n a vehicle.
- An un rest rained or imp roperly restrain­
ed ch ild ca n be injured or killed by be­
ing t hrown agains t th e ins ide of the ve­
hicle or by being e jected from it during
a sud den mane uver or impact.
- An unrestrained or improper ly res train­
ed ch ild is at much greater risk of injury
or death by be ing struck by an inflating
airbag.

I nfants up to about one year (20 lbs . or 9 kg)
are best protected in specia l infant carriers
and chi ld safety seats des igned for their age
group. Many experts believe that infants and
small children should ride only in special re­
straints in which the child faces the back of
the vehicle. These infant seats support the ba·

136 Child Safet y
Booster seats and safety belts
Properly used booster s eats 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. (57 inches/1 .45 meters) tall.
Fig . 120 Passenger seat: child proper ly rest ra in ed in a
booster seat
The vehicle's safety belts alone will not fit
most children until they are at least 4
ft. 9 in .
(57 inches/1.45 mete rs) tall and weigh about
80 lbs . (36 kg). Booster seats ra ise these chil­
dren up so that the sa fety belt will pass p rop ­
erly over the stronger pa rts of their bodies
and the safety belt can help protect them in a
crash.
.. Do no t use the co nvertible locki ng retractor
when using the vehicle's safety belt to re­ strain a chi ld on a booster seat .
.. The shoulder be lt must lie as close to the
center of the child 's collar bone as possible
and must lie and snug on the upper 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 f lat and snug . Pull on the be lt
to t ighten if necessary.
Ch ildren up to at least 8 years old (over 40
l bs. or 18 kg) are best protected in ch ild safe­
ty seats designed fo r their age and weight . Ex­
pe rts say that the ske leta l structure, pa rticu­
larly the pelvis, of these ch ildren is not ful ly
developed , and they m ust not use the vehicle
safety belts without a suitab le child restraint.
It is us ually best to put these childre n in ap­
propriate booster seats . Be sure the booster
seat meets all applicab le safety standards. Booster seats raise the seating position of the
c
h ild and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the right p laces. The
ro uting of the belt over the child's body is very
important for the child's protect ion, whether
o r not a booster seat is used .
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 port io n of the vehicle's
safety belt alone to restrain any ch ild, regard­
less of how big the chi ld is. A lways remember
that children do not have the prono unced pel­
vi c structure required for the proper funct ion
of lap be lt portion of the vehicle's three point
lap and shou lde r belts . T he child 's safety ab ­
solutely requires that a lap belt port ion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
belt portion of the safety be lt pass over the
c hi ld 's stomach or abdomen.
In a crash, a irbags must inflate within a blink
of a n eye and wi th considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be the re to protect t he occupant
as the occupant moves forwa rd into the a ir­
bag .
A vehicle occupant who is out of posit ion and
too close to the a irbag gets in t he way of an
inflating airbag . When an occupant is too
cl ose, he or she w ill be struck v iolently and
will receive serious or possibly even fatal in ­
Jury .
In order for the airbag to offer prote ction, it is
importan t that a ll vehicle occupa nts, espe cial­
ly any childre n, who m ust be in t he front se at
because of exceptiona l circumstances , be
proper ly restrained and as fa r away from the
airbag as possible. By keeping room between
the chi ld's body and the front of the passen­
ger compartment, the airbag can inf late com­
pletely and prov ide supplemental protection
in certain frontal collisions .
..

A WARNING ,~ ~
Not using a booster seat, us ing the boos­
ter seat improperly, incorrectly install ing a
booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous pe rsonal injury and death in a co llision
or other emergency s ituation. To help re­
duce t he risk of serious persona l injury
and/or death:
- T he shoulder be lt mus t lie as close to t he
center o f the child's co llar bone as poss i­
ble and must lie and snug on the upper
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 f lat
and snug . Pull on the belt to t ighten if
necessary .
- Failure to properly route safety belts over a ch ild's body will cause severe inju­
ries in an acc ident or other emergency
situation
¢ page 100 .
-Children on the front seat of any car ,
even with Adva nced A irbags, can be seri­
o usly injured or eve n killed when an a ir­
bag inf lates.
- Never let a child stand or knee l on the
sea t.
- Never let a child ride in the ca rgo a rea of
yo ur vehicle .
- Always remember that a ch ild lean ing
forwar d, sit tin g s ideways o r out of posi­

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled 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 electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually 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 we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 141
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
B.J in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficu lt driving situations as at lower
speeds.
Always adjust your speed and driving style to
road, traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by usin g the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys -
tem and anti-slip regu lation (ASR). ESC is
Ill>

•

142 Intelligent technology
switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
l!l . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -toc k brak ing system (ABS)
ABS prevents the wheels from lock ing up
when braking . The vehicle can still be steered
even during hard brak ing . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to brake the vehicle .
Brake assist sy stem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presse s the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake peda l until the situation is over .
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, accelerate and drive up hills.
E lectronic differential lock (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL a utomatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and ED L can not ove rcome
t h e laws of phy sics. This is espe cial ly im ­
por tant on slip pery or wet ro ads .
If th e
sys tems begin a ct in g to stab ilize your ve­
hicle, you shou ld imme diately change
yo ur speed to match the road and traffic
condit ions. Do not let the inc reased safe­
ty provided by these systems tempt you to take risks. Do
ing so w ill increase the
risk of a loss of veh icle control, co llision
and serious pe rsonal injuries .
- Always adapt your speed to road, traffic

Braking
General information
What affects braking efficiency?
Operating conditions and d riving habit s
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat­
i ng cond itions and dr iv ing habits
c:> & . On
ve hicles that a re e ithe r dr iven mostly in stop­
and-go city traffic o r a re driven ha rd , the
b rake pads should be checked by yo ur auth or­
iz ed A udi dealer more often th an specifie d in
the
Warranty & Maintenance booklet . Fail ure
to have your b ra ke pads inspected can res ult
in red uced b rake performance.
O n steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the engine . This way, yo u preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously . P u mp the brakes at inter­
va ls.
N oises may occur w hen braking depending on
the speed, bra king force and outside condi ­
tions s uch as temperature and h umidity.
Moisture or road salt
Unde r cert a in co ndi tions, for examp le, w hen
d riving through wate r or ve ry heavy rain , or
even after washing yo ur vehicle , the braking effect can be
reduced due to mois ture (or in
freez ing cond itions ice) on the brake pads. A
f ew cautio us brake applications s hou ld dry off
the brake pads or remove any ice coatings.
T he effec tiveness of the brakes can be red uce d
whe n the vehicle is d riven on a sa lt -covered
road and the b rakes are not used . Likewise,
yo u clean off acc umulated salt coat ing from
brake d iscs and pads with a few cautio us ap­
plicat ions o f th e b rake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
t h e d iscs if the car is not driven regu larly or
o n ly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads a nd d iscs by braking
firmly a few times from a moderately h igh
s p eed
c:> & .
Faults in the brake system
If you shou ld notice a sudden increase i n
brake pedal trave l, then one of the two brake
c ircuits may have fa iled

Low brake fluid level
Malfunctions ca n occ ur in the bra ke system if
t h e b rake fluid level is too low. The brake flu id
level is monitored electronica lly.
Brake booster
T he br ake boos ter inc reases the pressure tha t
yo u genera te with the b ra ke peda l. It works
