New brake pads
Remember that new brake pads do not have a f ull braki ng
e ff e ct during the first 250 miles (400 kilometers) after they
are i nsta lle d.
New bra ke pads have to be "burnished in" before they have opt ima l
grab=> &.
Dur ing the break -in period, you sho uld avoid putting severe loads on
the brakes. Severe loads incl ude, for example, sudden hard braki ng,
in particu lar at very high s peeds or, for examp le, on mountai n passes.
& WARNING
New brake pads don 't have the be st stopping power and must be
" broken -in " during the initial 100 to 150 miles (150 to 200 kilo­
meters ) of normal cit y driving. You can compensate for thi s by
pressing th e brak e pedal more firmly. This also applies lat er wh en
new pad s are installed. n
Catalytic converter
It is very important that your emissio n contr ol system
(catalytic converter) is functioning prop erly to ensure
that your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline==> page 283, "Fue l su pp ly" .
- Never ru n the tank down a ll th e way to empty .
- Never put too m uch motor oil in your engine==>
page 294,
"Adding engine o il - Never try to push- or tow-start your veh ic le .
The catalytic converter is an efficient "clean- up" device bu ilt into the
exha ust syste m of the ve hicle. The cat alytic converte r burns many of
the polluta nts in the exhaust gas before they are released into the
atmosphe re.
Th e e xcl usive use of unleaded fuel is cr itic ally important for the life of
the catalytic converter and proper f unction ing of the engine.
& WARNING
• Do not park or operate the vehicle in areas whe re the hot
exhaust sy stem may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or ru stproofing on or
near the exhaust manifold , exhaust pipes, catalytic conve rter or
heat shield s. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank filling wit h leaded fu el wi ll alrea dy
ser iou sly degrade the performan ce of the ca talyt ic co nve rter.
• Do not exceed the correct engine oil leve l=>
page 294 .
• Do not dr ive unti l the f uel tank becomes complete ly empty. The
eng ine could misfire . Unburned fuel could a lso get into the exha ust
system and th is could cause the catalytic converter to overheat.
• Do not t urn o ff the igni tion whi le the ve hicle is moving.
• Do not continue to operate your vehicle under these conditions, as
o therwi se fuel c an reach the cat alytic c onve rter. Th is cou ld resu lt in
over heating of t he converte r, requiring its rep lacement.
• T o ass ure eff ic ient operat ion of the Emi ssion Co ntro l System:
- Have your vehicle maintained properly and in accordance with
t h e se rvice recommenda tions in your Warranty
& M aintenance
booklet. •

in. WARNING
To reduce the risk of personal injury if you must change the engin e
oil in your vehicle your self:
• Wear eye protection.
• To reduce the ri sk of burns from hot engine oil, let the engine
cool down to the touch.
• When removing the oil drain plug w ith your finger s, stay as far
away as possible. Always keep you r forearm parallel to the ground
to help prevent hot oil from runn ing down your arm .
• Drain the oil into a containe r designed for this purpo se, one
large enough to hold at lea st the total amount of oil in your
engine.
• Engine oil is poisonous . Keep it well out of the reach of chil­
dren.
• Continuous contact w ith used eng ine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.
0 Note
N ever m ix o il add itives w it h your eng ine oi l. These additives can
damage your engine and adverse ly affect your Audi Limited New
Vehicle Warranty .
ffi For the sake of the environment
• Before chang ing yo ur o il, firs t ma ke s ure you know w here yo u can
proper ly dispose of the used oi l.
• Always dispose of used eng ine o il properly . D o not dump it on
garden soi l, wooded areas, into open streams or down sewage drains.
• Recycle used engine o il by taking it to a used eng ine oil collection
facility in your area, or contact a serv ice stat io n. •
Engine cooling system
Coolant
The engine coo lant performs two functions: i t keeps the
en gine fro m overhe ating and i t protects the engine fr om
fre ezing in th e winter .
The cooling system is sea led and genera lly requ ires little attention .
Th e cool ing sy stem h as been filled at the f actory wit h a permanent
coo lant which does not need to be changed . T he coolant cons ists of a
mixt ure of water an d the manufacturer's glycol -basedcoolant ad di­
tive Gl2++ antifreeze w ith anticorros ion addit ives (50% for USA
mode ls; 60% for Canadian models). This mixture both ass ures the
necessary frost protect ion and p rotects meta l components in th e
eng ine's cooling system from co rrosion an d scaling. It also raises the
boiling point of the cool ant.
Do not red uce the concentration of the coolant in the summer by
add ing p la in water. The proportion of coolant additive must be at
least 50 % but not more than 60 %
to maintai n antifreeze protection
and coo ling efficiency. If the coolant frost pro tect io n i s too low, t he
coo lant co uld free ze and damage t he veh icle heating an d eng ine
coo ling system.
For yea r- round drivi ng , antifree ze is added at t he factory for tempe r­
atures dow n to:
• - 31°F( -35°C)USA
• -40
°F ( -40 °C) Canada .
You can mi x the Gl2+ + coo lant additive wit h other additives (G12 + or
Gl2) . Always check with you r autho rized Aud i dea ler .
in. WARNING
Before you check anything in the engine compartment , always
read and heed all WARNINGS =>
& in "Working in the engine
compartment " on
page 289.

0 Note
• Before winter sets in, have the coolant checked to see if the
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
coo lant additive to 60% .
• When adding coolant additive to your cooling system, remember:
-We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed 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 coolant. Adding radiator repair 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 coo lant level
The engine coolant level can be checked with a quick
glance.

compartment: Coolant
expansion tank
Vehicle OP-eration
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 289.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank=> fig. 247 . 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 locat ion of the coolant expans ion tank can be seen in the engine
compartment illustration=>
page 290.
To obtain an accurate reading, the engine must be switched off.
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
coolant loss, the cooling 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 only if the boiling point of the
coo lant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Redu ce
the risk of scalding from hot coolant
by following these steps.
• Turn off the engine and allow it to cool down.
