work when the engine is running. With
the ignition turned off, you have to apply
more force when steering or braking.
S ince you cannot steer and stop norma l­
ly, this can lead to accidents and ser ious
injuries.
(D Note
- If the engine has been under heavy load
for an extended period of time, heat
builds up in the engine compartment af­
ter the eng ine is sw itched off -there is a
risk of damaging the engine . Allow the
engine to continue to run at idle for a
short time or drive until it has cooled
down before you turn it off¢

@ Tips
After the engine has been switched off, the
radiator fan can continue to run for up to
10 minutes -even wit h the ignition switch­
ed off. It can also sw itch on again after
some time if the coolant temperatu re rises
as the result of heat bu ildup or if the en­
gine compartment is heated by the s un's
r ays and the engine is hot.

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 has been filled at the fac ­
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly­
col-based coolant additive Gl2++ ant ifreeze
with ant icor rosion add itives (SO% fo r USA
models; 60% for Canad ian models).
Checkin g and fillin g 181
Coolant additive
The percentage of the coo lant add itive de­
pends on the climatic cond itions in wh ich the
vehicle is operated . If the percentage of
freeze protection i n the coo lant is too low, the
coolant can freeze, leading to a failure o f the
cooling and heating circuit.
T he percentage of coolant addit ive has al­
ready been adjusted at the factory for the ve­
hicle's climatic conditions.
T he m ix rat io for USA models is SO% wa ter
and SO% coolant addit ive, for Canadia n mod­
els 40% water and 60% coolant additive. This
mixture both ass ures the necessary frost pro ­
tection (-31 °F/-3S °C for USA models, -40 °F/-40 °C for Canada models) a nd protects
metal components i n the engine's cooling sys ­
tem from corrosion and scaling. It also ra ises
t h e boili ng poi nt of the coo la nt.
Summer time
Do not reduce the concentrat ion of the cool­
ant in the summer by adding p la in water.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main­
ta in an tifreeze pro te cti on and cooling eff ic ien­
c y.
A WARNING
B efore you c hec k anything in the engi ne
compartment, a lways rea d and heed a ll
WAR NIN GS~ .&.
in Working in the engine
compartment on page 175.
CD Note
- Be fore winter sets in, have the coo lant
checke d to see if the coolan t additive in
your vehicle is sufficient to meet the cli­ mate conditions. This is especia lly impor ­
tant if you live in a region where t he win­
ter is extreme ly cold. If necessary, in­
crease the p ropo rtion of coo lant add itive
to 60% .

Coolant loss
Coolant loss may indicate a leak in the cooling
system. In t he eve nt of cool ant los s, the cool­
ing system should be inspec ted immedi ately
by your a uthorized Audi dea ler . I t is not
eno ugh mere ly to a dd coo lant .
ll-

In a se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
- The cooling system is under press ure. Do
not open the cap of the coolant expan­
sion tank when the eng ine is hot. You
risk being scalded .
- The coo lant add itive, and therefore the
coolant itse lf, is hazardous to health.
Keep the coolant additive in the origina l
co nta iner out of the reach of children.
It
is a poison hazard.
CD Note
Do not add any type of rad iator leak seal ­
ant to your vehicle's eng ine coolant. Add­
ing radiator repair f luid may adve rsely af­
fect the fu nction and performance of your
coo ling system and could res ult in damage
not covere d 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 175 .
.. Add coolant .
.. Tw ist the cap on again
t ightly.
.. Tighte n the cap (D ¢ page 182, fig. 146
again .
Replacement engine coolant must conform to
exact specifications ¢
page 181, Coolant. If
the coolant additive Gl2++ is not available in
an emergency, you must not add any other ad­
d itive . In th is case, use only water and restore
the co rrec t mix ratio wi th the specified cool­
ant add itive as soon as possib le.
Always use
new engine coolant when ref illing .
Do not fill coolant above the " MAX" mark. Ex­
cess coolant will be forced out through the p ressure relief valve i n the cap when the en ­
g ine becomes hot .
Checking and fillin g 183
With a major loss of coolant, you shou ld add
the coolant only when the engine has
cooled.
In this way you prevent engine damage.
A WARNING
- The cooling system is unde r pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps .
- Turn off t he engine and allow it to coo l
down.
- Protect you r fa ce, hands and arms from
escaping fluid and steam by covering
the cap with a large, th ic k rag.
- Turn the cap s lowly and very carefully
in a counter -clockwise direction while
applying light, downward pressure on
the top
of the cap.
- To avoid being bu rned, do not spill an­
tifreeze or coolant on the ex haust sys ­
tem or hot engine pa rts. Under certain
cond itions, the ethylene glycol in en­
gine coolant can catch fire .
- Antifreeze is poisonous . Always store an­
tifreeze in its origina l container and well
out of the reach of children .
- If you dra in the coo lant, it m ust be
caught and safely stored in a proper con­
taine r clearly marked " poison" .
CD Note
- Coolant pollutes the environment and
cou ld cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure relief valve in the cap w hen the en­
gine becomes hot .
- If, in an eme rgency, o nly wate r can be
added, the co rrec t ratio between wa ter
and antifreez e
¢page 181 must be re­
stored as soon as poss ible.

(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
batte ry .
- 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 cou ld leak out .
- Battery ho lder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 185, Working on the battery be­
fore performing any work on the batte ry.
@ For the sake of the environment
