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.

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. .,.. •

A WARNING
Sudden tire failure can lead to loss of con
tro l, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fl uid away from t ires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo

A WARNING ,~
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the instructions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so.
@ Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 229.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs . They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is moving. If the tightening torque is
too high, the wheel bolts and threads can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb(± 10 Nm). Torque wheel bolts diago
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel .,.
