Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many au to manufactur ­
ers is carbon deposit build- up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
f a cturer to ano ther, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
pa rts, such as fue l injectors and intake valves . Al ­
though most gaso line brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine o f peak performance.

Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel f uel w it h concen tratio ns of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel i nfo rmat ion for e asy recog nition by
the user.
If the d iesel f ue l pump is no t labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be su re to check befo re t raveling to
other countries .
UL SD No . 2 c an become thic ke r i n ve ry cold tem­
peratures, and this can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
sole ly for use with ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
cove red by your New Vehicle Limited War-
r a nty.

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.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, always read and heed all WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 220 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive Gl2+ + or Gl3 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS

page 220 .
Park your vehicle on a level surface .
.,. Switch off the ignition .
.,. Read the engine coolant level from the coo lant
expansion tank
¢ fig . 201, ¢page 222. With a
cold engine, the coolant level should be be-
tween the "min" and "max" markings. When .,.

Checking and Filling
the engine is warm, the level may be slightly above the "max" marking.
The location of the coolant expansion tank can be
seen in the engine compartment illustration
¢ page 222.
To obtain an accurate reading, the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 15 will il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
electric coolant level sensor, we still recommend
you check the coolant level from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer.
It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
_& WARNING
The cooling system is under pressure and can
get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of the
cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certain conditions,
the ethylene glycol in engine coolant can
catch fire.

(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢.& in Working in the engine compartment on
page 220 .
.. Requirement: There must be a residual amount
of coolant in the expansion tank ¢(D .
.. Turn off the engine .
.. Let the engine cool down .
.. Place a thick rag over the coolant expansion
tank ¢
page 22 7, fig. 201 and carefully twist
the cap counter-clockwise ¢&, .
.,. Add coolant mixed in the correct ratio
r::!> page 22 7, Coolant up to the MAX marking.
.. Make sure that the fluid level remains stable.
Add more coolant if necessary .
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to ex­
act specifications ¢
page 22 7, Coolant.
We recommend using only coolant additive G12+
+, G13 or in an emergency G12+ . Do
not use a
different additive. In an emergency use plain wa­
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark . Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.

., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 202, ¢page 222. The brake flu ­
id level must be between the "MIN" and "MAX"
mark ings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
¢ page 222.
The fluid level may drop slightly after some time
due to the automatic 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
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14 . Do not continue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or other q ualified facili ty and the
cause corrected.
If the brake f luid level is too
low, the brake warning/indicator light will i llumi ­
nate. Contact an authorized Audi dealer
immedi­
at ely.

Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­ rosion in the brake system may result after ape­
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
eve ry
two y ears . Always use new brake fluid which con­
forms to Feder-al Motor Vehicle Standard "FMVSS 116 DO T 4".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the brake fluid changed by your author ized
Audi
d ea ler . Your dealer has the correct tools, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­ ficat ion
J 1703 and conforms to Federal
Motor Ve hicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake f luid .
The correct type of brake f luid is also indi­
cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long .
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle .
