- How fast the vehicle was traveling.
These data can he lp provide a better under­
standing of the circumstances in which crash­
es and injuries occur. NOTE: EDR data are re­
corded by your vehicle only if a non-trivial
crash situation occurs; no data are recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, could
comb ine the EDR data with the type of per ­
sonally identify ing data routinely acquired
during a crash invest igation.
To read data recorded by an EDR, special
equ ipment is required, and access to the veh i­
cle or the EDR is needed . In add ition to the ve­
hicle manufacturer, other parties, such as law
enforcement, that have the special equip­
ment, can read the information if they have
access to the vehicle or the EDR.
Some state laws restrict the retrieval or down­
loading of data stored by EDRs installed in a
vehicle for the express pu rpose of retr ieving
data after an accident or crash event without
the owner's consent.
Aud i will not access the EDR and/or sim ilar
data or give it to others -
- unless the vehicle owner (or lessee if the ve­
hicle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju­
dicial discovery process .
- Audi may also use the data for research
about vehicle operation and safety perform­
ance or provide the data to a third party for
research purposes without identifying the
specific vehicle or information about the
identity of its owner or lessee and only after
the recorded vehicle data has been ac-

Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emis­
sion control, airbags, and safety belts.
T hese electronic control modu les record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modules is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very lim ited period of
time, or stored when a system fault is detect­
ed by a control module. Some of the data
stored may relate to vehicle speed, direction,
or braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also only be read and downloaded
with special equipment that is directly con­
nected to the vehicle.

can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma intained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaus t gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service
If you wou ld like to take your vehicle out of
service for a longer t ime, contact your author­
ized Audi dealer or qualified repair facility.
They will advise you of important measures,
such as corrosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors: -your
personal driving style
- operating conditions
- technical limitations
If you ant ic ipate what you need to do next and
drive econom ically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle '
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fue l consump­
tion, engine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emissions and en­
gine noise increase disproportionate ly at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption wi ll
be reduced by one half. Never drive faster

than the posted speed limit and weather con­
ditions permit. Reducing unnecessary idling
Even wh en your car is just idling it burns up
fuel.
.,. Shu t the engine off when you a re not dr iv ing
the vehi cle.
... Do not warm up the vehicle by letting the
engine run at idle.
It is effic ient to switch off the eng ine when
stopped at railroad crossings and long red
lights. Turning the engine
off for just 30-40
seconds saves more fu el than is burned by
starting the engine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is wa rming up. So you should
drive away as soon as you start the eng ine and
avoid running at h igh RPM while the engine is
still warm ing up.
Do not leave engine idling unattended af­
ter starting. If warning lights should come on to indicate improper operation, they
wou ld go unheeded. Extended idling also
p roduces heat, which cou ld result in over­
heating or other damage to the vehicle or
other prope rty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have your vehicle serv iced at regular inter-
vals.
H aving your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . T he condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
c onsum ption.
Dri ving and the en vironm ent 199
Chec k your oil e ach t ime you fill your tank.
T he amou nt of oi l used is re lated to engine
load a nd speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output .
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as hea t shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
... Try to avoid dr iving sho rt distances with a
cold engine .
T he eng ine and catalytic conve rter have to
reach their optimal operati ng t emperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a co ld eng ine in a mid-s ize
ca r only achieves a fuel economy of 6 -8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg ..,.

220 Check ing and F illin g
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden so il, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
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 sea led and generally re­
q ui res little attention .
The cooling system has been filled at the fac­
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -based coolant addi -
tive G l3 antifreeze with anticorrosion addi­
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces­
sary frost pro tection and protec ts metal com­
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil­
i ng po int of the coo lant .
Do not red uce the concentr ation of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficie n­
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35°C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .
.&, WARNING "---
Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS ~
page 214.
0 Note
- Before wi nter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
ma te conditions. This is especi ally impo r­
tan t if you live in a reg ion where the win­
ter is extreme ly cold . If necessary, in­
crease the p roportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to yo ur
cooling system, remembe r:
- We recommend us ing on ly coola nt ad­
d itive Gl2++ or Gl3 (check the labe l)
fo r your vehicle. This coolant additive is

Other types of antifreeze can sign ifi­
ca ntly reduce corrosion p rotection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to yo ur vehicle's engine coolant .

258 Tires and wheels
It is important that the inflation pressu re is
regularly checked and maintained at recom­
mended levels .
Fo r more informat ion please ask your A udi
dealer for more details .
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n o rder to minim ize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer . Replace a damaged
t ir e as soon as possible.
- Inspect your tires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause t ire failure.
If you believe that a
t ir e may have been damaged, replace the
tire as soon as possible.
- T hese tires may wea r more quickly than oth­
ers.
- Please a lso remember that, while these tires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance ti
res or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those circumstances, you
should equ ip your vehicle with all-season or
winter tires, which offer better traction unde r
those conditions. We suggest you use the rec­
ommended snow o r all-season tires specified
for your vehicle, or thei r equivalent.
Refer to~ page
255 for more detailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly when co ld and in­
flated to the inflat ion pressure recommended
by the vehicle man ufactur er on the veh icle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in ­
flation pressure label, you should determine
the proper t ire inflation pressure for those
t i res).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
t ir es is signif icantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possible, and inflate them to the
proper p ressure. Driving on a sign ificantly un ­
der -inflated tire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al­
so reduces fuel eff iciency and tire tread life,
and may affect the vehicle's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
