Child seats
Infant seats
Babies and infants up to about one year old and
20 lbs . or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.

Booster seats and safety belts
Properly used booster seats 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. 177 Rear seat: child p roper ly restrained 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 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these ch ildren up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and must lie flat 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 flat and snug. Pull on the belt to tight­
en if necessary .
.,. If you must transport an older chi ld in a boos­
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .

Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in chi ld safety seats de­
signed for their age and we ight. Experts say that
the skeletal structure, part icularly the pelvis, of
these children is not fully developed, and they
Child safety
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicab le 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 be lt over the chi ld's body is very important
for the ch ild's protection, whether or not a boos­
ter 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 inches/
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 a lone
to restrain any ch ild, regard less of how big the
ch ild is. Always remember that child ren do not
have the pronounced pelvic structure required for
the proper function of lap be lt portion of the ve­
hicle's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snug ly and
as low as possible around the pe lvis. 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 considerab le 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 occu­
pant moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close , he or she
will be struck violently and w ill receive serious or
possibly even fata l injury .
In order for the airbag to offer protect ion, it is
important that all vehicle occupants, especially
any children , who must be in the front seat be­
cause of exceptiona l circumstances, be properly
restrained and as far away from t he airbag as
poss ible. By keeping room between the child's ..,_

body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supplemental protection in certain frontal
collisions.
.,&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing 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 situation. To help reduce the risk of se­
rious 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 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 injuries in an
accident or other emergency situation
~ page 143.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restraint in place
~page 67. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
- Never let a child stand or kneel on any seat, for example the front seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
any way during an accident can be struck by
a deploying airbag . This will result in serious
personal injury or death.

-If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the

Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt 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 is locked so that the child and
child safety seat will stay in place .
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 . ..,.

Child safety
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-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 .
A 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 Ad­
vanced 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 in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­ cumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight-mat in the seat and register a heavi­ er weight in the Advanced Airbag System.
The heavier weight registered can make the
system work as though an adult were on the
seat and deploy 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, immediately in­
stall 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 secure a
child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat .
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
~ .& .
.. Push the child safety seat down with your 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 un­
til 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 con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to pull the belt
out of the retractor. The convertible locking re­
tractor is now activated.
.. Make sure that the red release button is facing
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 improp­
erly 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 retrac­
tor 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.

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.
_&. WARNING ~
A child in a rearward-facing child safety seat i nsta lled on the front passenger seat will be
se riously inju red and can be ki lled if the front
a ir bag inflates - even wi th an Advanced Airbag
Sys tem.
- The inflating airbag will h it the ch ild safety

Electronic Stabilization
Control (ESC)
Description
The Electroni c Stab ili z at ion Control (ESC) re infor­
ces driver safety. It reduces the r isk of slipping
and improves driving stability. ESC detects crit i­
cal s ituations suc h as the vehicle overstee ring
and understeering o r the wheels sp inning. The
ve hicl e is stab ilized by applying the b rakes o r re­
ducing e ngine torque . Once t he ESC is acti ve , the
i n dicator light
m bli nks in the instrument cl us­
ter.
The fo llow ing sys tems a re integrated in the ESC:
Anti-lock b rake system (ABS)
ABS preve nts the wheels from lock ing up when
b raking . The veh icle can sti ll be steered even dur ­
i n g ha rd brak ing . Apply steady press ure to the
b rake pedal. Do no t pump t he pedal. A pulsing in
the brake pedal indicates tha t the system i s help ­
i n g you to br ake the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis ­
tance . It increases brak ing power when the d river
p resses the brake pedal q uic kl y in eme rgency si t­
uations . You m ust press and hold t he b rake pedal
until the situa tion is over. In vehi cles w it h ad ap­
tive cruise contro l* , the brake assist system is
mo re sensit ive if the distance detected to the ve ­
h icle ahead is too small.
Anti -slip regulation (ASR)
A SR re duces eng ine power when the drive w heels
begin to spin and adapts the force to the roa d
conditions. This makes it easie r to sta rt, acceler ­
ate and drive up hi lls.
190
Electronic differential lock (EDL)
The EDL brakes wheels that are spi nning and
transfers the drive power to the other w heels .
This function is not ava ilable at higher speeds.
I n ext reme cases , ED L automat ica lly swi tches off
to help keep the b rake on the bra ke d whee l from
overheating . EDL will sw itch on again automa ti­
ca lly w hen conditions have returned to normal.
Steering recommendation
The ESC he lps to stabilize the vehicle by cha ng ing
t h e s teer ing torque .
On vehicles with dynam ic steering*, ESC helps
stab il ize the steer ing in crit ica l sit uat ions .
Selective wheel torque control
Selective wheel torque cont rol is used when d riv­
i ng o n curves. The front whee l on the inside of
the curve or both wheels on the i nside of the
curve are braked selectively as needed . Th is al­
l ows mo re prec ise driving in c urves . The applica­
ble sys tem may not a ctivate w hen d riv in g in we t
o r snowy cond it ions.
_8. WARNING
- The ESC and i ts integ ra ted systems cannot
overcome the laws of physics . This is espe ­
cially important on slippery or wet roads. If
the systems begin act ing to stab ilize your
veh icle, you should immediately change
your speed to matc h the road and traffic
conditions. Do no t let the increased safe ty
provided by t hese systems tempt yo u to
t ake risks. Doing so will i ncreas e th e risk of
a loss of vehicle con trol, collisi on and se ri­
ou s person al injur ies .
- Always a dap t your spee d to road , traffic and
weather condi tions. The risk of los ing con ­
t rol of the vehicle in cr eases w hen driving

slippe ry or wet roads, and when driving too
close to ve hicles up ahea d. The ESC and its
integ rated systems cannot always prevent
col lisions - there is still a risk of accidents!
- Always accelerate w ith special ca re on even,

The brakes on today 's au tomobiles a re still s ub­
ject to wea r, depend ing la rgely on ope rating con­
ditions and driving habits¢.&. . On vehicles that
ar e e ither driv en most ly in stop-and -go city traf­
f ic or are driven ha rd, the brake pads should be
checked by your authorized Aud i dealer more of­
ten than specified in the
Warranty & Mainte­
n ance boo klet .
Failure to have your brake pads
inspected can resu lt in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the eng ine . This way, you prevent unnec ­
essary wear on the brake system . If you must use
your b rakes , do not ho ld the brakes down con tin­
uously. Pump t he b rakes at intervals.
Operating noise
Noises may occur when braking depend ing on the
speed , braking force and outs ide cond itions such
as tempe rature and humidity .
Effect of water and road sa lt
In certain situations, for example a fter driving
t hrough water, in heavy ra in , after overnight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake applica tions.
At highe r speeds and with the windsh ie ld w ipers
turned on, the bra ke pads press aga inst the brake
rotors for a short amount of time . Thi s occ urs at
r egular intervals wit hout the d river noticing and
p rovides for be tter br ak e response time u nder
wet conditions.
The eff ectiv eness of the brakes can be reduced
when the vehi cle is dr iven on a salt-covered road
and the brakes are not used. L ikewise, you clean
off acc umu la ted salt coat ing from b rake discs
and pads with a few ca utious applications of the
b rake ¢.&. .
Corrosion
There may be a tende ncy for d irt to b uild up on
the brake pads an d cor ros io n t o fo rm on the discs
if the ca r is not driven regular ly or only fo r sho rt
trips with little use of the brakes .
Intelligent Technology
If
the brakes are not used frequent ly, or i f co rro­
sio n has formed on the discs , it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ .&, .
Faults in the brake system
If you shou ld notice a sudden inc rease in brake
peda l travel, t hen one of t he two brake circ uits
may have fai led ¢

The brake booster increases the press ure that
yo u generate with the b rake peda l.
It only oper­
ates while the eng ine is r unning or w it h t he igni­
tio n sw itched on (hybr id drive*) ¢.&, .

--
-New brake pads don't have the bes t stop ­

Intelligent Technology
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­ ate the limits of physics . Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•) appears
r=:; page 33.
What you should know
The highest priority is given to maintaining start ­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no­
tice energy management actively regulating the
distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period. Some of the con­
venience functions may not operate, such as the interior lights or the power seat adjustment . The
convenience functions will be available again
when you switch on the ignition and start the en­
gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI" functions,
the battery is being discharged .
If starting capability is jeopardized due to energy
consumption, a message appears in the radio or MMI* display . The message indicates that the
system will be switched off automat ical ly in a
196
moment. If you wish to continue using the func­
tions, you have to start the engine .
With the engine running
Although electrical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
To bring the energy balance back into equilibri­
um, consumers which require especially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo ­
rarily cut back or switched off . These systems will
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 additional energy required is generat­
ed and the battery is charged.

Driving and th e en vironm ent
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat sh ields . During dr iv ing, the substance
used for undercoating could overheat and
cause a fire .
{U) Note
-Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct engine oil level
c:>page224 .
-Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converte r to overheat.
- Do not turn off the ignition while the vehicle
. . 1s moving.
- Do not continue to operate your vehicle un ­
der these cond itions, as otherwise fuel can
r each the catalytic converte r. This could re­
su lt in overheating of the converter, requir­
i ng its replacement .
- To assure efficient operation of the Emis ­
s ion Control System:
- Have your vehicle maintained properly and in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet .
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states . This depends on the su lfur
content of the fuel be ing used. Using a differ­
ent brand of fue l may he lp, or filling the tank
with lead-free super grade gasoline.

Diesel particulate filter
Applies to vehicles: with diesel engine
The diese l particulate filter filters near ly all of
the soot particles out of th e exhaust. The filter
cleans itself automat ically under normal d riving
conditions. If the filter cannot clean itself (for ex­
ample, because you are only driving shor t distan­
ces), the filter becomes clogged with soot and

- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do no t bottom out and ge t damaged.
This is espec ially true for vehicles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cu t your fuel

give you some tips on how you can he lp the envi­
ronment and your pocketbook.
(D Tips
T he consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre ­
spond to your act ual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
.. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel ­
erate less . Let the vehicle coast whenever possi­
b le -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving a t moderate speeds saves fuel and im­
proves your mileage .
.. Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces f uel consumption,
engine wear, and does not disturb the environ­
ment.
F ue l cons umption, exha ust emissions and engine
noise increase d isproportionately at high speeds.
If yo u drive at approximately three quarters of
top speed, fuel consumpt ion w ill be reduced by
one ha lf. Never drive faster than the posted
speed limit and weather conditions perm it .
Driving and the envir onment
Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the eng ine off when you are not driving
the vehicle.
.. Do not warm up t he vehicle by lett ing the en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi­ c ient to sw itch off the engine in veh icles without
the Start-Stop-System* when stopped at ra ilroad
c ross ings and long red lights . T urning the engine
off fo r just 30-40 seconds saves mo re fue l th an is
bur ned by s tarti ng the eng ine again .
It takes a long time for the eng ine to warm up
fully when it is ru nning at id le. However, wea r
and noxious emissions are especially high w hen
t h e engine is war ming up. So yo u should dr ive
aw ay as soon as you star t the eng ine and avoid
runn ing at high rpms w hile the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling unatt ended after
start ing. If wa rning lights sho uld come on to
i ndicate impro per operation, they would go
u nheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle o r othe r proper­
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.. Have your vehicle serviced at regular interva ls.
By hav ing your vehicle regular ly serv ice d by an
authorized Aud i dea ler helps to ensure that it
runs properly and economically . T he cond ition o f
yo ur vehicle not on ly affects its safety and ability
to hold its value , it also affects
fuel consump­
tion .
Check your oil each time you fill your tank.
T he amou nt o f oil used is related to engine load
and speed. .,,.
