thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com partment could start a fire .
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal in
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of R tronic to "N"
(Neutral); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact
ing hot parts . Tie back hair before
starting, and wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
.&_ WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm .
- Battery posts, terminals and related ac cessories contain lead and lead com
pounds, chemicals known to the State of California to cause cancer and
reproduc
tive harms. Wash hands after handling.
@ Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam
age to vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu
ids, have your vehicle inspected by an au
thorized Audi dealer.
Closing the engine compartment lid
... Make sure that the rear spoiler is retracted
~page 152.
""Pull the engine compartment lid down until
the pressure from the struts is reduced.
.., Press the engine compartment lid closed
c::>& .
A WARNING ,_
A engine compartment lid that is not com
pletely latched could fly up and block your
view while driving.
- When you close the engine compartment lid, check it to make sure the safety catch
has properly engaged . The engine com
partment lid should be flush with the
surrounding vehicle body parts .
- If you notice while driving that the en

@ Tips
If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consu lt your a uthor
ized Audi deale r to have the cause of your
concern properly d iagnosed . Keep in m ind
that the accurate measurement of oil con
sumpt ion re quires great care and may take
some time. Your author ized A udi dealer

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% .
-
-Only Gl2+ +, an additive meeting specif i
cat io n "T L-VW 774G" may be used as a
coolant additive. Oth er coo lant add itives
IJJ,
•
•
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.
