push it shut;
it may fail to engage=> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area
=> & .

Engine cooling system
Coolant
The engin e coolan t p erforms two fun ctions: it ke ep s t he
en gine from overheati ng and i t protects the engine fr om
fr eez in g in th e winte r.
Th e cooling system is sea le d and genera lly requ ires lit tle at tention.
Th e cooling system has been f illed at th e factory w it h a p erm anent
coo lant which does not need to be changed. T he coolant cons ists o f a
mix tur e of wa ter a nd the manufacturer's gly co l-basedcoolan t addi ­
tive
Gl2+ + antifreeze with anticorros ion addit ives (50% for USA
m odels; 60 % fo r C an ad ian models). This mixture both as su re s th e
necessary frost protect ion and protects meta l components in the
eng ine's coolin g sy stem fr om co rrosion and scaling .
It als o ra ises the
boiling point of th e coolant.
Do not re duce the concentration of the coo lant in the summer by
add ing p la in wate r.
The proportion of coolant additive must be at
least 50 % but not more than 60%
to mai ntain antifreeze protection
an d co olin g efficiency . If the co ola nt frost p ro te ct ion i s to o low , the
coo lant co uld freeze and damage the veh icle heating and engine
cooling system.
For year -round drivi ng, antifreeze is added at t he factory for tempe r-
atures down to: .,,

• -31°F(-35°C)USA
• -40°F ( - 40°() Canada .
You can mix the Gl2+ + coolant additive with other additives (G12+ or
G12). Always check with your authorized Aud i dealer.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS =>
& in "Work ing in the engine
compartment" on
page 280.
0 Note
• Before winter sets in, have the coolant checked to see if th e
coolant additive in your vehicle is sufficient to meet the climate
conditions . This is especially important if you live in a region where
the winter is extremely cold .
If necessary, increase the proportion of
coola nt additive to 60% .
• When adding coolant additive to your cooling system, remember:
- We recommend using only coolant additive Gl2++ (check the
label) for your vehicle . This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can significantly
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 coolant . Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by yo ur New Vehicle Limited Warranty .•

Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig. 223 Engine
compartment: Coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS ~ & in "Working in
the engine compartment" on
page 280 .
-Turn off the ignition.
- Let the engine cool down .
- Place a thick rag over the coolant expansion tank
~ fi~ . 223 a nd carefully twist the cap counter-clockwise
~& -
- Read the engine coolant level in the open coolant expan­
sion tank~ fig. 223 . With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max" marking .
The location of the coolant expansion tank can be seen in the engine
compartment illustration=>
page 281.
To obtain an accurate reading, the engine must be switched off. ~
Vehicle care Do-it-yourselt service iTechnical data

-~_C_ h_e _c_ k_ i_ n ....: g:::e._ a_ n _ d_ f_il _l _in _ g =- --------------------------------------------
The expansion tank in your vehicle is equipped with an electric coolant
level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System ~
page 29 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
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 cooling system should be inspected immed iate ly by
your authorized Audi dealer .
It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• 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 antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coo lant. Adding radiator repair fluid may adverse ly affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty.•
Adding coolant
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 280.
-Turn off the engine .
- Let the engine cool down.
- Place a thick rag over the coolant expansion tank
=> page 287, fig. 223 and carefully turn the cap counter­
clockwise ::::,
&.
- Add coolant .
- Twist the cap on again
tightly.
Replacement engine coolant must conform to exact specifications
~ page 286, "Coolant". Even in an emergency, if coolant additive
G12 ++, G12+ or G12 is not available, do not use a different additive.
Use plain water instead until you can get the correct additive 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. Excess coolant will be
forced out through the press ure re lief va lve in the cap when the
eng ine becomes hot .
& WARNING
• The cooling system is under pressure and can get very hot.
Reduce the risk of scalding from hot coolant by following these
steps.
-Turn off the engine and allow it to cool down. _.,
