2013 AUDI TT Owner´s Manual

oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­based engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
" sludge," that over t ime can lead to expensive
repairs .
At the time of printing, engine oils available in the U .S . and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean,
however, that every synthetic engine oil will
meet Audi oil standard VW 502 00 . So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posits use only oil with the following specifi­
cations printed on the oil container :
Audi oil standard VW S02 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards .
Viscosity
Engine oils are graded according to their vis­
cosity . The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem­
perature ranges for normal driving conditions.
However, if engine oil viscosity grade SAE
SW40 is not available, you can also use viscos­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil quali ty standard VW 502 00
specifications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that expressly conforms to the
Checking and filling 183
VW 502 00 specification, in case you have to
top
off the oil while on the road.
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oil
that expressly conforms to Audi oil standard
VW 502 00 specifications is available - may
you top
off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only
in viscosity grades SA E SW-40, SA E 5W -30, or
SAE OW-40. However, during the entire time
between oil change intervals, never top
off
with more than a total of 0.5 qt/liter engine
oil that does not conform to Audi oil specifica­
tion VW 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your autho rized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa .com or
www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author ­
ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
should even be changed more frequently. Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.

184 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::;, page 159) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
II lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 185. Top off the
o il at your earliest conven ience
c::;, page 185 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS

CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at regular intervals, pr ef­
erably ea ch time you refu el, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.

@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authori zed Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
always read and heed all WARN·
INGS
¢ & in Working in the engine compart­
ment on page 180 .
The engine oil must be changed according to
the intervals specified in your Warranty &
Maintenance booklet. This is very important
because the lubricating properties of oil di ­
minish gradually during normal vehicle use .
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe­ riods. Detergent
additives in the oil will make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex­
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station .
If you choose to change your oil yourself,
please note the following important informa­
tion:
A WARNING
=
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil off thoroughly
with soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.

@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
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
qu ires little at tention.
The cooling system has been filled at the fac ­
tory with a permanent coolant which does not n eed to be changed. The coolant consists of a
mixture of wa ter and the man ufacturer's g ly ­
col-based coolan t addi tive Gl3 ant ifree ze
with ant icorrosion add itives (50% for USA
models; 60% for Canadian models) . This mix­
ture both assures the necessary frost protec ­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling 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 add itive must be at
lea st 50°/4 but not more than 60°/4
to ma in­
tain antifreeze protection and cooling efficien­ cy. If the coolant frost pro tect io n is too low,
the coolant cou ld freeze and dam age the veh i­
cle heating and eng ine cooling system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.

A WARNING
Before you c heck anything in the engine
compartment, always read and heed all
W ARNI NGS~ &.
in Working in the engine
comportment on page 180.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your v ehicle is sufficient to meet the cli­
mate conditions. This is especia lly impo r­
t an t if you live in a region where t he win­
t er is ex treme ly cold. If ne cessary, in­
cr ease t he p ro portion of coo lant add itive
to 60%.
- Whe n adding cool ant additive to yo ur
c ooling sys tem, remember:
- We recommend us ing on ly coolant ad­
d itive Gl2++ or Gl3 (check the labe l)
for your veh icle. This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Othe r types of antifree ze can sig nifi­
cantly reduce cor ros io n protec tion. The
res ulting co rrosion can cause a loss of
coolant an d serio us en gine damage.
- Do not add any type of rad iator le ak seal­
ant to yo ur vehicle 's eng ine coolant .
Adding radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by you r New Ve hicle

Checking the engine coolant level
The engine coolant level con be checked with
a quick glance.

188 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 180.
• Park your vehicle on a level surface.
• Switch the ignition off.
• Read the coolant level at the coolant expan­
s ion tank ¢
page 182, fig . 134. With a cold
engine, it must be above the "min" mark .
With a hot engine, it ca n be a little above
the indicated range .
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration
¢ page 182.
To obtain an accurate read ing, the engine
must be switched off.
The expansion tank in yo ur vehicle is equipped
with an e lectric coolant level sensor .
When the coo lant level is too low, the warning
light in the A uto- Check System ¢
page 16 will
illuminate until yo u add coo lant and the level
has been restored to normal. Even though
there is an electric coo lant level sensor, we
still recommend you check the coolant leve l
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 author ized 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 overheat ing.
(D Note
Do not add any type of radiator lea k seal­
ant to your vehicle's eng ine coolant. Add­
ing radiator repair f luid may adversely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­

• Add coo la nt.
• Twis t the cap on aga in
t ightly.
Replacement engine coolant must conform to
exact spec ificat ions ¢
page 18 7, Coolant.
Even in a n emerge ncy, if coolant add i-
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d iffe ren t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amount o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
Alw ays use

Do not fill coola nt above the "MAX" mark. Ex­
cess coola nt wi ll be fo rced o ut through the
pressure relief valve in t he cap w hen the en­
gine becomes hot.
,&. WARNING ~ -
- T he cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps.
- T urn off the engine and allow it to coo l
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering
the cap w ith a large, t hick rag.
- T urn the cap s lowly a nd ve ry carefully
in a counter-clo ckwise direction while
applying light, downward pres sure 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".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess 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¢
page 187 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.
Radiator fan
The radiator fan switches on automatically by
itself
The electric radiator fan is controlled by ther­
moswitches that switch on and off depending
on coolant and engine compartment tempera­
tures.
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operation conditions.
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off.
It can even switch
on again later by itself
c::> &., , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
Checking and filling 189
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er 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 au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
