- Lack of proper maintenance as well as improper use of the
vehicle will impair the function of the emission con trol system
and could lead to damage.
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the su lfur content of the fuel
being used. Using a different brand of fuel may he lp, or filling the
tank with lead-free super grade gasoline. •
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 not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
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 t ires largely depend on three factors:
• your personal driving style
• operating condit ions
• technical limitations If
you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumption by 10-15 percent . This
section will give you some tips on how you can he lp the environ­
ment and your pocketbook .
[ i ] Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which will vary
depend ing upon vehicle load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate 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 fuel consumption, engine wear, and
does not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by
9J,,

0 Note
Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty .
W For the sake of th e environm ent
• Before changing your oi l, first make sure you know where you
can properly dispose of the used oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil, wooded areas, into open streams or down sewage
drains .
• Recycle used engine oi l by taking it to a used engine oil collec ­
tion fac ility in your area, or contact a service station. •
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from overheating and it protects the engine from
freez ing in the winter.
The coo ling system is sealed and generally requires little attention.
T he coo ling system has been filled at the factory with a permanent
coolant which does not need to be cha nged . The coolant consists of
a mixture of water and the manufacturer's glycol-basedcoolant
addit ive G 12 + antifreeze with an ticorrosi on addit ives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling . It a lso raises
the boiling point of the coo lant .
Do not reduce t he concentration of the coolant in the summer by
adding plain water.
The prop ort ion of coolant additi ve mu st be at le
as t 50 % but not more th an 60 %
to maintain antifreeze protection
and co oling effic iency . If the coo lant fros t protect ion is too low, the
coolant could freeze and damage the vehic le heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper ­
atures down to:
• - 31 °F ( - 35 °C) USA
• -40 °F ( -40 °C) Canada.
You can mix the G12 + coo lant additive with other additives (f or
examp le G11 or G12l. Always check with your authorized Audi
dea ler .
& WARNING
Before you check anything in the engine compartment , alway s
read and heed all WARNIN GS
=:> & in "Working i n the engine
c ompartment " on
page 220.
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions . This is especia lly important if you live in a region where
the winter is extremely cold. If necessary, increase the proport ion o f
coo lant additive to 60%.
• When adding coolant additive to your coo ling system,
remember :
- We recommend using only coolant additive G12+ (check the
label) for your vehicle. This coolant additive is avai lable at autho ­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sea lant to your vehicle's
engine coolant. Adding radiator repair fluid may adverse ly affect the _.,
Vehicle care I t •

& WARNING (continued)
• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine is not running.
• The auxiliary radiator fan switches on automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops. •
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 155 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS =>
& in "Working in
the engine compartment" on
page 220.
- Read the brake fluid level from the brake fluid reservoir
~ fig. 155. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~
page 221 .
The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably below the "MIN" mark, the
brake warning/indicator light (U .S. models:
BRAKE , Canadian models:
ill) will come on~ page 20 and~ page 32. Do not continue to
operate the vehicle . The complete brake system should be thor­
oughly checked by an authorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid level is too low, the
brake warning/indicator light will illuminate. Contact an authorized
Audi dealer
immediately .•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid will als o
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi dealer . Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you.
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the reach of children!
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions : .,,_

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop ­
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special tools and spare parts as
we ll as the proper facilities for disposing of the old tires .
Authorized Audi dealers have the necessary information about tech ­
nical requirements for insta lling or changing tires and rims .
Rep lac ing t ires a nd w heels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni ­
toring system =>
page 251.
Always buy replacement radial tires t hat have the same specifica ­
tions as the tires approved for your vehicle by Audi . Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table
=>
page 242.
Audi -approved specification tires are specially matched to your
vehic le and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The tab le
( =>
page 242) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure labe l located on driver's side 8 -pillar (=>
page 242,
fig. 161) lists the spec ifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized in for­
mation on the sidewall of all tires=>
page 249, fig. 164 . T his informa­
tion identifies and describes the fundamenta l characteristics, the
quality grade of the tire and also provides a tire identification
number for safety standard certification and in case of a recall.
T ire s pec ifica tio ns
Know ledge of tire specifications makes it easier to choose the
correct tires . Radial tires have the tire specifications marked on the
sidewal l, for example:
P 2 45 / 45 R 17 95 H
This contains the following information :
P Indicates the tire is for passenger cars
24 5 Nominal tire width in mm of the tire from sidewall edge to side-
wa ll edge . In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial
17 Rim diameter code (in inches)
95 Load rating code
H Speed rating letter code
X L (or "xi", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein ­
forced" or an "Extra Load" ti re
M+ S (or "M/S") Indicates that the tire has some mud and snow capa ­
bility
The tires could also have the information of direction of rotation =>

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury .
• Always use tires , rims and wheel bolts that meet the specifica­
tions of original factory -installed tires or other combinations that
have been spe cifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehi cle control.
& WARNING (continued)
• All four wheels must be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle -for e xample with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faste r than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle must have a chassis designed
for run flat tires and a factory -installed tire pressure monitoring
system that indi cate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer o r tire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used, they must
be installed on all four wheels . Mixing tire types is not permitted. .,

Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same model::::;,
page 296.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi
dea ler o r qu alif ied wo rksh op.•
Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performan ce of low -aspect -ratio t ires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and alway s before a
long trip::::;,
page 244, "Checking tire p ressure".
What you can do to a void tire and rim damage
L ow a spect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_

Handling characteristi cs change wh en dri ving with
low air pressure or with flat tires even with special run ­
flat tires
A low pressure or flat front tire affects vehicle hand lin g charac te ri s­
t ics by pulling the vehic le slightly to the side where the tire is
mounted and reduces brak ing performance .
A low pressure or flat
rear tire also affec ts driving c haracteristics by
pul ling to the side where th e tire is mounted and also reduces
b raki ng per for mance . T he ef fec t o n ve hic le han dlin g is most n otice ­
able when driving around curves .
& WARNING
Changed vehicle handling characteristics when driv ing in the run­
flat mode can cause lo ss of vehicle control , a crash and serious
personal injury .
• Driving on special run-flat tires in the run -flat mode will change
vehicle handling characterist ics during braki ng , when cornering
and under heavy acceleration .
• Never drive faster than the max imum rated speed of 50 mph
(80 km /h) when driving in the run -flat mode .
• Always adjust vehicle speed to traffic , road and weather condi­
tions and drive slower than the maximum rated speed if nece ssary
weather and road conditions are taken into ac count .
• Always obey speed limits and other traffic laws .
0 Note
We always recommend driv ing with even more care when using
these special tires in the run -flat mode. A lways avoid sudden
m aneuvers. •
Applies to vehic les: with Run-f lat tires
Replacing run -flat tires and rims
Y our vehicle was especi ally des igned to use special run­
fl at t ires.
You may use and c ombi ne o nly approved run -flat t ires a nd specia l
matching rims that have been designed for run -flat tires. Mounting
special run -fla t tires o n stan dard wheels w ill not work and wi ll not
