Cooling system
Coolant
T he 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
qu ires little attention .
T he cooling system has been filled at the factory
with a permanent coolant which doe s not need to
be changed . T he cool ant consists of a mixture of
specia lly condit io ned water and the ma nufactur
e r's g lycol-basedcoo lant additive G 13 antifreeze
w ith a nticorros ion add itives (50% for USA mod
e ls; 60% for Canadian models) . Thi s m ixt ure bot h
a ssures the ne cessary frost protection and pro
tec ts meta l components in the engine 's cooling
system from corrosion and sca ling. It a lso raises
the boiling point of the coolant.
D o not red uce the conce ntra tion o f th e coo lant i n
the summer by add ing p la in wa ter.
The propor
tion of coolant additive must be at least 50% but not more than 60 %
to maintain antifreeze
protection and cooling efficiency . If the coolant
frost protection is too low, the coolan t could
freeze and damage t he vehicle heat ing and en
g ine cooling system .
For yea r-round driving, antifree ze is added at the
factory for tempe ratu res down to:
- -31°F ( -35°C) USA
- - 4 0°F ( - 40°C) C anada .
I f yo u mu st add coo lant, use a m ixt ure of wate r
a nd coolant add it ive. Mixing the coolant additive
with d istilled water is recommende d.
_& WARNING
Be fore yo u check any thing i n the engine com

@ Note
- Be fore winte r sets in , have the coo lant
checke d to see if the coolant additive in you r
vehicle is sufficient to meet the climate con diti ons. This is espec ia lly important if you
live in a region where the winter is extreme
ly cold . If necessary, increase the p ropo rtion
o f coolan t addi tive to 60%.
- Whe n adding coolant additive to your cool
ing system, remember :
- We recommend using o nly coo lan t add i
tive G12++ o r G13 fo r yo ur vehicle . This
coolant ad dit ive is available at author ized
A ud i dealers . Othe r types of antifreeze ca n
significantly reduce cor rosion protect ion .
The resulting cor rosion can ca use a loss of
coolant a nd serious e ngine damage .
- Do not add any type of rad iator leak sealant
to your vehicle's engine coolant. Adding ra diat or repa ir flu id may adverse ly affect the
function and perfo rmance of your cooling
system and cou ld result i n damage not cov
ere d by your New Vehicle Lim ited W arra nty .

Checking and Filling
"'Park your vehicle on a level surface.
"'Turn off the ignition.
"'Read the engine coolant level from the coolant
expansion tank
c:> fig . 200, <=> page 223,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark
ings . When 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 223 .
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
c::> page 29 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec
tric 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.
0 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

We recommend using only coolant additive Gl2+

or in an emergency Gl2+. 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 antifree ze 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.
A 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
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 223.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on¢
page 18 and ¢ page 28 . Do not
continue to operate the vehicle . The complete
brake system shou ld be thoroughly checked by an
author ized Audi dealer or qualif ied workshop and
the cause corrected. If the brake fluid level is too low, the brake warning/indicator light will illum i
nate. Contact an authorized Aud i dealer
immedi
a tel y.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake flu id abso rbs moisture from the a ir . If the
water content in the brake fluid is too high, cor rosion in the b rake system may result after a pe ri
od of time. The boiling point of the bra ke fluid
will also decrease conside rably and decrease
b ra ki ng per fo rmance .
Therefore, th e brake flu id must be changed
ev ery
tw o years .
Always use new b rake fluid w hich con
forms to Fede ra l Motor Vehicle Standa rd " FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re, we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer .
Your dealer has the cor rect too ls, the
right brake f luid and the know -how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old or inappro
pr iate brake fluid . Observe these precau
t ions:
230
- Use only brake fluid that meets SAE spec i
ficat io n
J 1703 and conforms to Federal
Motor Vehicle Sta ndard 116 . Always check
with your aut horized Aud i dea ler to make
su re you are using the correct brake fl uid .
The co rrect type of brake f lu id is also ind i
cated on t he b rake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the b rakes can cause a vapor lock if the
brake fluid is left in t he system too long.
This can se riou sly affec t the efficiency of
the b rakes as well as yo ur sa fety. This
could result in an acc ident .

possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom
mends using winter tires dur
ing the winter months . Low
temperatures significantly de crease the elasticity of summ
er tires, which affects traction

and braking ability. If summer
tires are used in very cold tem
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi
tions. The surface of the rims
does not have sufficient corro
sion protection for this and
could be permanently dam
aged by road salt or similar
substances.
