2013 AUDI TT maintenance

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
c::;, .& in Working in the engine
comportment on page 180.
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.

186 Checking and filling
on the hot engine and exhaust system
when the engine is running -fire hazard!
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
(D Note
- The oil level must not be above range 0
-danger of converter or engine damage!
Contact an authorized Audi dealer to
draw off oil, if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ 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.

190 Checking and filling
If the brake fluid level falls considerably b e­
l ow the "MIN" mark, the brake warning/ indi­
cator light (U .S . mode ls:
1111 , Canad ian
model s:. ) will come on
c> page 14 . Do not
continue to ope ra te the vehicle. The comple te
brake system shou ld be thoroughly checked
by an author ized Audi dealer or ot her quali­
fied fac ility and the cause corrected . If the
b rake fluid level is too low, the b rake war ning/
i ndicator ligh t w ill illuminate. Contact an a u­
thor ized A udi dealer
immediatel y.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
Brake fl uid abso rbs moist ure from the a ir. If
the wate r content in the b ra ke fluid is too
h igh, cor ros ion in the br ake sys tem may result
after a per iod of t ime . The bo iling point of the
brake fluid wi ll also decrease considerab ly and
decrease braking performanc e.
Therefore, the brake fl uid mus t be changed
every tw o year s. Always use new b rake fluid
which conforms to Federal Motor Veh icle
Standard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoi r can be difficul t to

have the brake f luid changed by yo ur autho r­
ized
Audi dealer. Your dea ler has the correct
too ls , the right brake f luid and the know-how
to do this for you.
A WARNING
- Brake fluid is poiso nous . It must be stor­
ed only i n the closed orig inal container
o ut o f the reac h of children!
- Brake fa ilure can result from old o r inap ­
propriate b rake fluid . Observe these pre­
caut ions :
- Use only bra ke fluid that meets SAE
specif ication
J 1 703 and co nforms to
Federal Motor Vehicle Standard 116 .
Always check with your a uthori zed Audi
dealer to ma ke sure you are using the
correct brake flu id. The correct type of brake flu
id is also ind icate d on the
brake f lu id rese rvoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapo r lock if
the brake fluid is left in the system too
long. This can seriously affect the effi­
c iency of t he brakes as well as your
safety . T his co uld resu lt in a n accide nt.
([) Note
Brake fluid will damage the paint of your
vehicle.
@ For the sake of the environment
Because o f the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
required and the necessary expertise, we
recomme nd that you have the brake flu id
changed by yo ur autho rize d Aud i deale r.
Battery
General information
Your vehicle is equipped with a specia l bat ­
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re­
placed with an origina l equipment battery .
U nder normal opera ting condit ions, the bat­
te ry is
maintenance-fr ee .
Have the battery checked when you take your
vehicle in for serv ice . You a re well advised to
replace a battery that is o lde r th an 5 years .
Disconnecting the battery terminals
Some vehicle functions (power window reg u­
lators, for example) are lost if the battery te r­
mina ls are disconnected . T hese functions have
to be relearned after the battery termina ls are
connected again . T o p revent t his, t he battery
shou ld only be disconne cted from the veh icle
elect ric a l sys tem when abso lutely ne cessary
f or rep air s.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period
of seve ral days o r weeks , e lectr ica l compo-
nents a re g radually cut back or switched off.
Ill-

This reduces energy consumption and main­
tains starting capability over a longer period
c::>
page 156. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven­
ience functions will be ava ilable again when
you switch on the ignition and start the en­
g ine .
Winte r oper ati on
During the winter months, battery capacity
tends to decrease as temperatures drop. This
i s because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capac ity of the vehicle bat­
tery before winte r sets inc::>
page 193. A we ll
charged ba tte ry w ill no t only prevent starting
prob lems when the weathe r is cold, but will
a lso last longer .
Replacing battery
The new battery must have the same capaci­
ty, vo ltage ( 12 volts), amperage, cons truction
and p lug sealing, as the origina l ba tte ry. Spec­
if ications are listed on the batte ry housing.
Batteries specially developed by A udi fulfill
the maintenance, output, and safety require­
ments.
When insta lling the battery, make sure the ig ­
nition and all electrica l cons umers are switch­
ed off c::>
(i).
We recommen d that yo u use ma intenance­
free or
cy cle- re sis tant /leak-pr oof batteries
according to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from Apri l
2010).
Replacing the batte ry should be carried by a
q ua lified workshop. P lease follow the instruc­
tions on the battery cover.
Checkin g and fillin g 191
@ Note
-All work on the battery requires techni­
cal know ledge. Please contact an Audi
dealership or another authorized fac ility
for questions about the battery - danger
of ac id burns and exp losion hazard!
- The battery must not be opened! Do not
try to change the battery 's liquid level,
otherwise detonating gas will escape
from the battery - explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec­
t ro lyte for this batte ry is abso rbed into a
special glass mat. This lea k-proof battery
must not be replace with a convent iona l
bat tery.
- Make su re the ventilation hose on t he
side of the ba ttery is connected, othe r­
w ise fumes or battery ac id can leak out.
- Batte ry holder and termin als always
have to be sec ured correc tly.
- Before all work on the batte ry follow the
warning s below c::> .&. in Working on the
battery on page
192 .
@ For the sake of the environment
Because of the p rob lem of proper disposal
of a ba ttery, we recommend your author­
i zed Audi dealer change the bat tery fo r
you. Batteries contain sulfuric acid and l ead and must always be disposed of prop ­
erly in comp liance with a ll environmental
regulat ions. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ro nment. Make sure that the removed bat­
tery cannot overbalance, othe rwise sulfu­
r ic acid might escape!
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored w here it w ill not freeze. This will
p revent it from be ing dam aged and h aving
to be replaced .

206 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 144 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly p laced around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 202 .
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 145.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 22 7 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A whee l must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop.
all-wheel drive
Vehicles with quattro ® mus t always have tires
of the same size, construction and tread type .
