same kind of child rest raint offered by child
restraint manufact urers.
The weight ranges fo r the ind ividual types,
makes and mode ls o f chi ld restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir­
bag System. When a child restraint is being
used on the front passenger seat with a typi­
cal 1 year-old ch ild, the Advanced Airbag Sys­
tem compa res the we ight measured by the
weight sensing mat with the informat io n sto r­
ed i n the ele ct ron ic cont ro l uni t.
The electron ic control unit also registers the
tension on the front passenge r safety belt .
The tens io n on the safety be lt fo r the front
passenger seat will be d iffe ren t for an ad ult
who is prope rly using the safety belt as com­
pared to the tension on the be lt whe n it is
used to attach a chi ld restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger meas ures the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whether there is a ch ild restraint w ith a typ ical
1 year-o ld child o n the front passenger seat
and whe ther or not the ai rbag must be tu rned
off.
Child restraints and Advanced Airbags
Regardless o f the child restraint t hat you use,
make sure that it has been ce rtified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with a n airbag. Always be sure
that the child restraint is properly instal led at
one of the rear seat ing pos itions .
If in excep­
tional c ircumstances you must use it on the
fro nt passenger sea t, caref ully read all of the
i n format ion on c hild safety and Advanced A ir­
bags and heed a ll of the app licab le WAR N­
I NGS . Ma ke certain that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
fro nt passenger airbag is turned off and that the a
irbag sta tus is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
h ave been available over the yea rs, new mod­
els are introduced regu larly incorporating new
and improved designs and o lde r mode ls are
ta ken out o f product ion . Ch ild restra ints are
not standard ized . Child restraints of the same
type typically have different weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they are insta lled on a vehi­
cl e seat. These d iffe rences make it v irtually
i mpossible to certify compl ian ce wi th t he re­
quiremen ts for advanced airbags with eac h
and every chi ld restraint that has eve r been
sold in the past or wi ll be sold over the course
of the useful life of your veh icle.
F or t his reason, the United S tates National
Highway T raffic Safety Adm inist ration has
published a list of specific type, ma kes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag

Braking
What affects braking efficiency?
New brake pads
D uring the first 250 mi les (400 km), new
brake pad s do not possess the ir full b rak ing
effect, they have to be "broken in" first¢ &.
The break- in period can be considerably lon-
-
ger for ve hicles w ith ceram ic b rake rotors* . ll>

You can compensate for th is sligh tly re duced
brak ing power by push ing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condit ion s and d riv ing hab it s
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are either driven mostly in stop­ and-go city traffic or are driven hard, the brake pads should be checked by your author­
i zed Audi dealer more often than specified i n
the
Warranty & Maint enan ce booklet . Failure
to have your brake pads inspected can result
in reduced b rake performance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessary wea r on the brake system. If you
must use you r brakes, do not hold the brakes
down continuously. P ump the b rakes a t inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braki ng force and outside condi­
tions such a s tempe ratu re a nd h umidity .
Due to the nature of the materials used i n ce ­
ramic brake rotors*, nois es may become more
apparent at low speeds.
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, i n heavy ra in, after over night
condensation or after washing your car, the
b rak ing effect can be reduced by moistu re or
i ce on the bra ke roto rs and b rake pads . The
b ra kes must be dried fi rs t w it h a few caref ul
b ra ke app lications.
At h igher speeds and with the w indshield w ip­
e rs turned on, the brake pads p ress against
the brake rotors for a short amount of time.
This occurs a t reg ular in tervals wi tho ut the
d river noticing and provides for better brake
response time un der wet conditions.
The effectiveness of the brakes can be reduced
when the vehi cle is dr iven o n a salt -cove re d
Int ellig ent technolog y 179
road and the b ra kes are no t used. Likewise ,
you clean off acc umulated salt coating from
brake d iscs and pads with a few cautio us ap ­
plications of the brake
9 ,&. .
Due to the ir sur face character istics, ceramic
brake rotors* absorb moisture i n such condi­
tions. T his can cause a tempo rary reduction in
braking force compared to dry brakes. Yo u can
compensate for this by pressing the brake
pedal harder .
Corrosio n
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly 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, i t is adv isable
to clean off the pads a nd d iscs by braking
firmly a few times from a moderately high
speed
9 &. .
Fault s in the brake sy stem
If you shou ld notice a sudden increase in
brake pedal travel, then one of the two b rake
c ircui ts may have failed ¢&. .

Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronica lly.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
au thorized Aud i dea ler helps to ensure that it
runs properly and economic all y. The condition
of your veh icle not on ly affects its safety and
ability to hold its va lue, it a lso affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

190 Cleaning and protection
Automatic car wash
Th e ve hicl e can be washed in almost any
modern automatic car wash .
The vehicle paint is so du rable that t he ve hicle
can normally be washed without problems in
an automatic car wash . However, the effect on
the paint depends to a large extent on the de­
sig n of the facility, the filte ring of the wash
wate r, the type of wash and care mater ia l, etc.
If th e p aint ha s a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately.
If necessary, use a different car wash.
Th e power top does no t require special pre ­
cautions be fore passing through a car wash.
However , the car mu st not be treated with
hot wa x after the wash cycle!
The wax could
adversely affect the power top and even dam­
age the fabric ove r a period of time.
The power top does not have to be washed ev­
e ry time you use a car wash . The power top
can be spared if the car wash facility is equ ip­
ped with manually adjustable roof brushes or
rollers.
Before going through a car wash, be sure to
take the usual precaut ions such as clos ing the
windows . Remove antenna if applicable.
I f yo u have installed additional accessories on
the vehicle - such as spoilers, etc. - it is best to
ask the car wash operator i f these should be
removed.
On ly use car washes where the vehi cle re ­
mains stationary and the cleaning equipment
moves around the vehicle wh ile washing and
drying. It is not recommended to use car
washes where the vehicle is moved forward on
a conveyer.
A WARNING
- Always read and heed all WAR NIN GS and
ot he r i nforma tio n
¢ page 189.
(D Note
- Before wash ing the ve hicle in an auto­
matic ca r wash, please make su re to re­
tract the exter ior mir rors to prevent
them from be ing damaged .
- Compare the w idth of yo ur vehicle with
the width of the tunne l at the facility.
- Compa re the track of yo ur vehicle with
the distance between the g uide rails of
the facility -there is a risk of damage to
the whee ls and tires.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­
cle by hand.
.,. Before yo u start washing, ma ke s ure you
have read a nd understood the WARNINGS
¢ .&, .
.,. First soak all dried d irt unt il it is soft, then
r inse it off .
.,. As you clean yo ur vehicle, start w ith t he roof
and wo rk your way down to t he bo ttom, us­
ing a sponge, a s ponge g love or a clean
br ush .
.,. Rinse the s ponge o r th e sponge g love o ften,
flushi ng it clean eac h time .
.,. Use spec ia l car shampoo only for very persis ­
tent dirt .
.,. Rinse the car t ho roughly with water.
.,. Use a chamo is leather to gently wipe the ex-
t er ior d ry .
U se a separate sponge for cleaning the
whee ls, door s ills and othe r regions exposed
to road dirt . In this way, yo u w ill not scratch
t h e pa int w ith coarse pa rticles imb edded in
t h e sponge the next time you wash t he ca r.

210 Check ing and filling
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum ­
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 to he lp keep your vehicle's engine
running smoothly and help prevent the for­
mat ion of harmfu l deposits, sometimes called
"sludge ", that ove r time can lead to expensive
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW -30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is a t or be low the
min imum mark -and no oi l that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top
off
with a high quality engine o il, preferab ly syn ­
thet ic-based, tha t mee ts ACEA A3 or API SM
specifications, but even then , only in v iscosity
grades SAE SW-40 , SAE SW-30, o r SA E
OW-40. However, dur ing the entire time be­
tween oil change inte rva ls , never top
off with
more than a total of 0.5 q t/ liter engine o il
t h at does not con form to Audi oi l specification
vw 502 00.
For more informa tion about eng ine oi l tha t
has been approved for your veh icle, please
contac t either yo ur authorized Aud i deale r or
Audi C ustome r Re lations at 1 (800) 822 -2834
or visit our web site at www .audiusa.com or
www.aud icanada .ca. Here you w ill also find a
current list of oils (manufacturers, brand
names e tc.) tha t conform to Audi oil s tanda rd
vw 502 00 .
Changing the engine oil
The eng ine oi l and oil fi lter must be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil ca n reduce eng ine performance and
can lead to expensive engine repa irs .
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­ ing proper ties of oil decrease gradually during
norma l veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
shou ld even be cha nged more frequent ly .
Change oil more often if you drive mostly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
di tions, o r when you use your vehi cle where .,..

214 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the fac­ tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-basedcoolant additive G13 antifreeze with
anticorrosion add itives (50% for USA models;
60% for Canadian models). This mixtu re both
assures the necessary frost protection and
protects metal components in the engine 's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant .
Do not reduce the concentration of the cool­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 S °C) USA
- -40 °F ( - 40 °C) Canada .
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~
A in Working in the engine
compartment on page 207.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in- crease the
proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using on ly coolant ad­
ditive G12++ or G13 for your vehicle.
This coolant additive is availab le at au­
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion cah cause a loss of coolant and se­
rious engine damage.
- Do not add any type of rad iator leak seal­
ant to your vehicle's engine coolant .
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
· Checking the engine coolant level and
adding coolant
Be very careful when adding engine coolant.

If the brake fluid level falls considerably be ­
l ow the "MIN" mark, the brake warning/indi­
cator light (U.S . mode ls:
1111 . Canad ian
models: .) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the brake warn ing/
in dicator light w ill illuminate. Contact an a u­
thor ized Audi dealer
imm ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician .
Brake fluid absorbs moistu re from the a ir. If
the water content in the brake fluid is too
hi gh , corrosion in the b rake system may resul t
after a per iod of t ime . The bo iling po int of t he
b rake fluid w ill also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y two year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake flu id rese rvoi r ca n be difficult to
r eac h, therefore , we recommend th at yo u
h ave the brake f luid changed by yo ur autho r­
ized
Audi dealer . Your deale r has the correct
too ls, the right brake fluid and the know -how
to do th is for you.
A WARNING
- Brake fluid is po isonous . It must be stor­
ed only in the closed orig inal container
out of the reac h of children!
- Brake fa ilure can result from old or inap­
propr iate brake fluid . Observe these pre­
caut ions:
- Use on ly bra ke fluid that meets SAE
specification
J 1 7 03 and conforms to
Checkin g and fillin g 217
Federa l Moto r Ve hicle Standard 1 16 .
Always check with your authorized Audi
dealer to make sure you are using the correct brake fluid . The correct type of
brake flu id is also ind icated on the
brake f luid rese rvoir .
- The brake fluid must be new . Heavy use
of the brakes ca n cause a vapo r lock if
the b rake fluid is left i n the system too
l ong. This can se riou sly affect the effi­
c iency of the brakes as well as your
safe ty . T his co uld resu lt in an accident.
(D Note
B ra ke fluid wi ll damage the paint o f you r
vehicle.
@ For the sake of the environment
Because of the p rob lem of proper disposal
of bra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecomme nd th at yo u have the br ake fl uid
changed by yo ur autho rized Aud i dea le r.
Battery
General information
Un der normal operating cond itions , the bat­
te ry in you r Audi does not need any ma inte­
nance . With
high outside temperatures o r
long da ily d rives we recommend that you have
