Engine cooling system
Coolant
The e ngine coolant perfor ms tw o functions: i t kee ps the
en gine from overheatin g and i t pro tects the engi ne from
freezing in the winter.
The cooling system is sea led and general ly requires litt le attention.
The coo ling sys tem has been f illed at the factory with a permanen t
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the ma nufacturer 's glyc ol- basedco olan t
additive
G12++ antifreeze w ith anti corrosion additives (50% for USA models; 60% for Canadian mode
ls) . T his mixture both assures the
n ecessary fros t pr otection a nd protects metal co mpo nents in the
engine's cooling system from corrosion and scaling. It also raises
t he boil ing point of the coolant .
Do not reduce the concentration of the coo lant in the su mmer by
adding plain water.
The proportion of coolant additive mu st be at
lea st 50 % but not more than 60 %
to maintai n antifreeze pro tection
and cooling efficiency. If the coolant frost protection is too low, the
coo la nt co uld free ze and damage the vehic le heating and engine
coo ling system .
For year-round driving, antifree ze is added at the factory for temper­
atures down to:
• - 31 °F ( -35 °C) USA
• -40 °F ( -40 °C) Canada.
You can mix the
G 12+ + coolant additive with other additives (G12+
or G12). Always check w ith your authorized Audi dealer.
& WARNING
Before you check anything in the engine compartment, alway s
read and heed all WARNINGS
~ & in "Working in the engine
compartment " on
page 217.
0 Note
• Before winter sets in, have the coolant checked to see if the
coo lant additive in your vehicle is suff icient to meet the c limate
co nd itions . This is e special ly impor tant i f you live in a region where
the winter is extremely cold. If necessary, increase the proportion of coo lant additive t o 60%.
• When adding coolant additive to your cooling system,
r emem ber:
- We recommend using on ly coolant additive
G 12+ + (check the
l abel) for your veh ic le . Th is coolant additive is available at autho -
rized Audi dealers. Other types of antifreeze can significantly ._

Checking and filling -
---------------------=----"=---------
reduce corrosion protection. The resu lting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adverse ly affect the
function and performance of your cooling system and cou ld result
in damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
gla nce .

e xpa nsion t ank
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compa rtment" on
page 217.
- Switch the ignition of f.
- Read the coo lant l eve l at the coo lant exp ansio n tank
==> fig. 142. With a col d e ngine, it must b e above the
"min" mar k. Wit h a hot engine, it can be a little above t he
indicated range.
The location of the coolant expansion tank can be seen in the
engine compartment i llustration. To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehic
le is equipped with an e lectric
coolant level sensor.
When the coolant leve l is too low, the warning light in the Auto ­
Check System =>
page 34 will blink un til you add coolant and the
level has been restored to normal. Even though there is an e lectric
coo la n t level sensor, 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 coo lant loss, the co oling sys tem shou ld be i nspected immedi­
ate ly by your authorized Audi dealer . It is not enough merely to add
coo lant .
In a
sealed system , losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating .
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant. Adding rad iator repair fluid may adversely affect the func ­
tion and performance of your coo ling system and could resu lt in
damage not covered by your New Vehic le Limited Warra nty. •
Adding coo lant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 217 .

not use a different additive.
Use p lain water instead until you ca n get the c orrec t addit ive and
can restore the correct ratio. This should be done as soon as possible.
If you have lost a considerable amount o f coo lant, then you should
add co ld antifreeze and cold water only when the engine is cold.
A lways use
new e ngine c oolan t when refil ling .
Do not fill coolant above the "MAX" mark. Excess coolant will be
forced ou t through the pressure relief va lve in the cap when the
engine becomes hot.
& WARNING
• The cooling sy stem is under pre ssure and can get very hot .
Reduce the risk of scalding from hot coolant by following these
s teps.
- Turn off the engine and allo w it to cool down .
- Protect your face, hands and arms from esc aping fluid and
steam by covering the cap with a large , thick rag .
- Turn the cap slo wly and very carefully in a counter -clockwise
dire ction while applying light , downward pressure on the top
of the cap .
- To avoid being burned, do not spill antifreeze or coolant on
the e xhaust system or hot engine parts . Under certain condi ­
tions, the ethylene glycol in engine coolant can catch fire .
& WARNING (continued )
• Antifreeze is poi sonous. Always store antifreeze in its original
container and well out of the re ach of children .
• If you drain the coolant , it must be caught and safely stored in
a proper container clearly marked "poison ".
0 Note
• Coo lant po llutes the environment and could cause an engine
fire. Excess coolant will be forced out through the pressure re lief
va lve in the cap when the engine becomes hot.
• If , in an eme rgency, o nly wa te r can be added, the correct rat io
between water and antifreeze=>
page 224 must be restored as soon
as possib le .
ffi For the sake of the environment
Drained coolant should not be reused. Always dispose of used
coo lant whi le observ ing all environmen tal regulat io n s. •

& WARNING
• To reduce the risk of personal injury never touch the radiator
fan.
• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine is not running .
• The auxiliary radiator fan switches on automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops. •
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 143 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 217.
-Read the brake fluid level from the brake fluid reservoir
=> fig. 143. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~ page 218.
The fluid level may drop slightly after some time due to the auto ­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level falls considerably below the "MIN" mark, the
brake warning/indicator light (U.S. models:
BRAKE, Canadian models:
(Cf))) will come on~ page 19 and~ page 33. Do not continue to
operate the vehicle. The complete brake system should be thor­
oughly checked by an authorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid level is too low, the
brake warning/indicator light will illuminate. Contact an authorized
Audi dealer
immediately. •
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
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
after a period of time . The boiling point of the brake fluid will also
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan­
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi dealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.

& WARNING (continued)
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury.
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground, that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position) (automatic transmission) or
Neutral (manual transmission) and the hand brake is firmly
applied.
<£> For the sake of the environment
• Changing the engine settings will adversely affect emission
levels. This is detrimental to the environment and increases fuel
consumption .
• Always observe environmental regulations when disposing of
old engine oil, used brake fluid, dirty engine coolant, spent batteries
or worn out tires.
