Engine 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 sea led and generally re­
q ui res lit tle at ten tion.
The cooling system has been filled at the fac­
tory with a pe rma nent coolant which does not
need to be changed. The coolant consists of a
mix ture o f wa ter and the m anu fa ctu rer 's g ly ­
col -based coolant addit ive Gl3 antifreeze
with anticorrosion additives (50% for USA mod els; 60% for Canadian models) . This mix ­
ture both assures the necessary frost protec ­
tion and protects metal components i n the
engine's cooling system from corrosion and
scaling .
It also raises the bo iling po int of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant addit ive must b e at
lea st 50% but not more than 60 %
to main­
tain antifree ze protection and cooling efficie n­
cy.
If t he cool ant frost pro tect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system.
Checkin g and fillin g 181
For year -round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.

WA RNIN GS
q .&. in Working in the engine
compartment on page 173 .
-
CD Note
- Before wi nte r sets in, have the coo lant
checke d to see if the cool ant a ddi tive in
yo ur vehicle is sufficient to meet the cli ­
mate conditions . This is especia lly impor ­
tant if you live in a region where the win­
ter is extreme ly cold. I f necessary, in­
crease the proportion of coo lant add itive
to 60% .
- When adding coolant additive to your cooling system, remember :
- We re commend using o nly coola nt ad­
di tive G l2++ or Gl3 (check the l abe l)
for your vehi cle. This coolan t additive is
ava ila ble at autho rize d Aud i dea le rs .
Othe r ty pes of antifreeze can sig nifi­
cantly reduce corros ion protection. The
resu lting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle 's engine coolant.

c:::> fig. 144.
Opening the coolant expansion tank cover
.. Stop the engine and allow it to cool.
.. Switch the ignition off .
.. Care fully remove the bolts in the cover@
using a screwdriver and remove the cover.
The coolant reservoir is located below
¢fig. 145.
Checking the engine coolant level
.. Place a rag or cloth on the cap of the coolant
expansion tank and turn the cap
carefully to
the left (counter-clockwise)
c:::> .&, .
.. Read the coolant leve l inside the coolant ex­
pansion tank¢
fig. 145. With a cold engine,
it must be above the "min" mark. With a hot
eng ine, it can be a little above the indicated
range.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped
with an electric coo lant level sensor
c:::> page 15. 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 cool­
ing 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 on ly if
the boiling point of the coo lant is exceeded as
a result of overheating .
A WARNING
-- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan­
sion tank when the engine is hot. You
ris k be ing sca lded.
- The coolant additive, and therefore the
coo lant itself, is haza rdous to hea lth .
Keep the coolant additive in the original

container out of the reach of children. It
is a poison hazard.
@ 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 Lim ited
Warranty.
Adding coolant
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS q A in Working in the engine compart­
ment on pag e 173.
"'Add coolant .
"'Twist the cap on again
tightly.
"'Tighten the cap (D q page 182, fig. 145
again.
Replacement engine coolant must conform to
exact specifications
q page 181, 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 water until you can get the correct addi­
tive and can restore the correct ratio. This
should be done as soon as possible.
If you have lost a considerable amount of
coolant, 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. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine 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.
Checking and filling 183
- 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 . Ex cess 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
q page 181 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.
Brake fluid
Have the brake fluid changed by an experi­
enced t echnician.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
afte r a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance. .,.. •

When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e . "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger.
Fastcharging a battery is
dangerous c::.> .&. in
Working on the battery on page 186 .
It re­
quires special charging equipment and the
knowledge to go with it. We recommend hav­
ing your battery fast charged only by a quali­
fied workshop .
A discharged battery can
freeze at tempera­
tures of only 32 °F (0 °C). Allow a frozen bat ­
tery to thaw completely before attempting to
charge it
c::.> & . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma­
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
WARNING
Charging a battery can be dangerous.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro-
zen. The battery housing may have

188 Checking and filling
cracked and weakened when the battery
froze.
- Charge the battery in a we ll ventilated
area. Keep away from open f lame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technicia n w ith the proper equip­
me nt.
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc., as we ll
as t he battery charger.
(D Tips
- The vehicle battery must not be charged
with a standard small charger that p lugs
i nto the c igarette lighte r o r outlet.
- Only charge the battery through the con­

What do I do now? 217
Jump-starting
General
If necessary, the engine can be started by
connecting it to the battery of another vehi ­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
us ing a
pair of jump er cabl es to start the en­
gine.
Both batteries must be rated at 12 volts . The
capacity (Ah) of the booster battery must not
be substantia lly less than the capac ity of the
discharged battery .
Jumper cables
Use only jumper cables of suff ic ient ly large
cro ss se ction to safely car ry the starter cur ­
rent . Refer to the manufacturer's specifica­
tions .
Use only jumper cab les which have
insulated
term inal clamps and are properly marked for
dist inction:
plu s(+) cable : in most cases colored r ed
m inu s(-) cable :
in most cases colored black
A WARNING ~
Batteries contain e lectric ity, acid, and gas .
Any of these can cause very serious or fata l
injury. Follow the instructions below for
safe handling of your vehicle's battery.
-Always shield your eyes and avo id lean-
ing over the battery whenever poss ible.
- A discharged battery can a lready freeze
at temperatures just below 32 °F (0 °(). Before connect ing a jumper cable , the
frozen battery must be thawed com ­
pletely, othe rwise it could explode .
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
wate r immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion. •

-Vehicle batteries generate explos ive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage or substant ially different "Ah" rating
may cause an explos ion and personal in­
Jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substant ially different capacity (Ah) rat­
