(D Note
- The oil level must not be above range G)
- danger of conver ter or eng ine damage!
Co ntact an authorized Audi dea ler to
draw off oil, if necessa ry.
- Audi does not recommend the use of oil
additiv es. They may damage the engine
and adverse ly affec t your New Vehicle

Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter
mines the freeze protection of the coolant 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 permanent coolant which does not
need to be changed. The coolant consists of a
mixture o f water and the man ufacture r's g ly
col-based coolant additive Gl3 ant ifreeze
w ith a nticorros ion add itives (50% for USA
models; 60% for Canad ian models). This mix
ture bot h assures the n ecessary frost protec-
Checkin g and fillin g 175
tion and protects meta l components in t he
engine's cooling system from corrosio n and
sca ling . It a lso raises the boiling point of the
coolant.
Do not reduce the concen tration of the cool
ant in the s ummer by adding p lai n wate r.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main
ta in antifreeze protect io n and coo ling eff ic ien
cy. If the coo la nt frost protection is too low,
t h e coolant could freeze and damage the vehi
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory fo r temperatures dow n to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada .
A WARNING ~
Before you chec k anything in the engi ne
compartment, always read and heed a ll
WARNINGS¢
& in Working in the engine
compartment on page 169.
-
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
mate condit ions. This is especially impor
t ant if you l ive i n a region where the win-
t er is extremely cold. If necessary, in-

a lwa ys r ead and heed all WARN
INGS ¢.&.. in Working in the engine compart
ment on page
169 and park your vehicle on a
level surface .
The coolant expansion tank is located in the right s ide of the convertible top storage bay
under the round metal cover¢
fig. 144 . The
convertible top must be in the service position
to check the coolant leve l
¢fig . 143 .
Bringing the closed con ve rtible top into
th e s ervic e position
~ Switch the ignition on .
~ Pull and hold the convert ible top switch .
~ Press and hold the rear window switch too
u nti l the convertib le top moves into the
service position¢
fig. 143.
Bringing the op en conv ertible to into the
service position
~ Switch the ignition on.
~ Press and hold the convertible top switch.
~ Press and hold the rear window switch too
until the convertible top moves into the
service position¢
fig . 143 .
Opening the coolant e xpan sion tank cover
~ Stop the engine and allow it to cool.
~ Switch the ignition off.
~ Carefully remove the bolts in the cover (D
using a screwdriver and remove the cover.
The coolant reservoir is located below
¢fig. 144.
Chec king the engine cool ant level
~ Place a rag or cloth on the cap of the cool
ant expansion tank and turn the cap
careful
ly
to the left (counter-clockwise) ¢ .&_.
~ Read the coolant level inside the coolant ex
pans ion tank ¢
fig. 144 . With a co ld engine,
it must be above the "min" mark. With a hot
eng ine, it can be a little above the indicated
range.
T o obtain an accu rate reading, the engine
must be switched off.
The expansion ta nk in your vehicle is equ ipped
with an electric coo lant level sensor
¢page 15. We still recommend you check the
c oolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool
i ng system shou ld be inspected immediately
by your aut horized Audi dea ler. It is not
eno ugh me rely to add coolant.
In a
s ea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING ,~
- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan
sion tank when the engine is hot . You
risk being scalded .
- The coolant additive, and therefore the coolant itself, is hazardous to health.
Keep the coolant additive in the original
container out of the reach of children. It
is a poison hazard.
(D Note
Do not add any type of radiator leak seal
ant to your vehicle's engine coolant. Add
ing radiator repair fluid may adversely af
fect the function and performance of your cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ¢ &. in Working in the engine compart
ment on page 169.
.. Add coolant .
.. Twist the cap on again
tightly .
.. Tighten the cap (D ¢ page 176, fig . 144
again.
Replacement engine coolan t must conform to
exact specifications ¢
page 175, Coolant . If
the coolant additive G12+ + is not available in
an emergency, you must not add any other ad
ditive. In this case, use only water and restore
the correct mix ratio with the specified cool
ant additive as soon as possible.
Always use
new engine coolant when refilling .
Do not fill coolant above the "MAX" mark. Ex
cess coolant will be forced out through the pressure relief valve in the cap when the en
gine becomes hot .
With a major loss of coolant, you should add
the coolant only when the engine has
cooled.
In this way you prevent engine damage .
Checking and filling 177
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 counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en
gine coolant can catch fire .
- Antifreeze is poisonous. Always store an
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con
tainer clearly marked "poison".
Q) Note
-Coolant pollutes the environment and
could cause an engine fire. Excess cool
ant will be forced out through the pres
sure relief valve in the cap when the en
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze ¢
page 175 must be re
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al
ways dispose of used coolant while observ
ing all environmental regulations.

182 Checking and filling
(D Note
- Your vehicle is equipped with a specia l
battery. Installing a different type of
battery can cause prob lems in the vehi
cle electrical system. When replacing the
vehicle battery, always install one with
the same spec ificat ions as the original
battery .
- Make sure that the gas venting hose is
always connected to the o riginal open ing
on the battery side. Otherw ise gasses or
ba tte ry acid could leak out .
- Battery holder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 179, Working on the battery be
fore performing any work on the batte ry.
@) For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you . Batteries contain sulfur ic ac id and
lead and must always be disposed of prop
erly in compliance with a ll environmenta l
reg ulations. D isposing of vehicle batteries
improperly is very dangerous to the envi
ronment. Make sure that the removed bat
tery ca nnot overbalance, otherwise sulfu
r ic acid might escape!

Clean water should be used when filling up. If
possible, use soft water to prevent scaling on
the washer jets . Always add a glass cleaner
solution (with frost protection in the winter) .
(D Note
- Do not mix engine coolant antifreeze or
any other additives to fill up the wind
shield washer reservoir.
- Do not use glass cleaners containing
pai nt so lvent; you risk damaging the
