Engine cooling system
Coolant
The e ngine co o la nt per form s two functio ns: it keeps the
engine from ove rh eati ng and it protects t he engine from
free zing in the winter .
The cooling system is sealed an d genera lly req uir es little attention. The cooling system has been f
illed at the factory wit h a permanent
c oo lant whi ch does no t need to be c hanged . Th e coolan t cons ists o f a
mixt ure of water and the manufacturer's glycol-basedcoolant addi ­
tive G12+ + antifreeze with anticorrosion ad dit ives (50% for USA
mode ls; 60% for Ca nadian models) . This mixture both ass ures the
necessary frost protection and protects meta l components in the
eng ine's cooling system from co rrosion and scaling. It also raise s the
boiling point of the coo lant .
Do not re du ce the co ncent ration of the coo lant in the summer by
add ing p la in water .
The proportion of coolant add itive must be at
least 50% but not more than 60%
to mai ntain an tifreeze pro tection
and coo ling efficiency . If the coolant frost p rotect io n i s too low, the
coo lant co uld freeze an d damage t he veh icle heating and engine
coo ling system .
For year-round driving, antifree ze is added at the factory for temper­
a tures dow n to:
• -31°F(-35°C)USA
• - 4 0 °F ( -40 °C) Canad a.
You can mix the G12 ++ coo lant addit ive w ith other additives (G12+ or
G 12). A lways check with yo ur autho rize d Audi dea ler.
& WARNING
Before you che ck anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 301 .
0 Note
• B efore w inter sets in, have the coolan t checked to see i f the
coo lant add itive in yo ur vehicle is s uff ic ient to meet the cl ima te
conditions. This is especially important if yo u live in a region where
the winter is ext reme ly cold . If necessa ry, increase the proport ion of
coo lant add itive to 60%.
• When ad ding coolant add itive to you r cooling sys tem, remembe r:_.,

-We recommend using only coolant additive Gl2 ++ (check the
l a bel) for yo ur vehicle. This coolant ad dit ive is available at au tho·
r ized Audi dealers . Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coo lant . Adding radiator repa ir fluid may adversely affect the
function and performance of your cooling system and could 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
glance .

~ & -
Vehicle OP-eration
-Read the engine coolant level in th e open coo lant expan ·
sion tank ~ fig . 2 3 7 . With a cold engine, th e coolant level
should be between the "min" and "max" ma rkings . Whe n
the engine is warm , the level may be slight ly above the
"max" marking .
The location o f the coo lant expans ion tank can be seen in the engine
compartment illustration=>

To obt ain an accurate reading , the engine must be sw itched off.
Th e expans ion t an k in your vehicle is equippe d with an electric coolant
level sensor.
When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 35 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can oc cu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and

CD Note
Never use a fast charger as a booster to start the engine. This will seri­
ously damage sens it ive electronic components, such as control units,
relays, radio, etc ., as well as the battery charger.•
Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Intelligent energy management in your veh icle is responsible for
distributing the electrical energy throughout your vehicle
~ page 263. The intelligent energy management system will keep
the engine battery charged better then vehicles without this system .
To make sure the additional electrical energy is available once again
after you have changed the battery, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing. Your authorized dealer must code the
battery in the energy manageme nt system to enable you to use the
energy management functions correctly after replacing the battery.
If it is not possible to use a battery of this type, the new battery must
have the same capacity, voltage (12 volts), amperage, construction
and plug sea ling. When
installing the battery, make sure the ignition and all electrical
consumers are turned off.
CD Note
Make sure the vent ilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
~ For the sake of the environment
Because of the prob lem of proper disposal of a battery, we recom­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfu ric acid and lead and must always be disposed
of properly in compliance w ith all environmental regulations.
Disposing of vehicle batteries imprope rly is very dangerous to the
environment. •
