2013 AUDI TT ABS

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
r each, therefo re , we recommend that yo u
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 .

remain continuous ly illuminated . This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signa l low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea­
sons, including the installat ion of replace­
ment or alternate tires or wheels on the veh i­
cle that prevent the TPMS from funct io ni ng
properly. Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 1 47 Disp lay : under infla tion warn ing
Using the ABS sensors, the tire pressure moni ­
toring system compares the t ire tread circum­
fe rence and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru­
ment clus ter with a warning symbol
RE and a
message
'* fig. 147. The dr iver message in the
d isp lay goes out after 5 seconds. The driver
message can be d isplayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on ­
ly one tire is affected, the display will indicate
its pos ition.
The ti re pressure monito ring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti-
Tire s an d wheel s 215
al and fu ll load pressure) or after changing o r
replacing a tire on your vehicle '*
page 216.
The TPMS indicator on ly mon itors the t ire
pressure that you have previously stored . You
can f ind the recommended tire pressures for
your vehicle on the label on the driver's door
pillar ¢
page 200.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire press ure in one or more tires is too
low,
- the tire has structural damage,
- the t ire press ure was changed, wheels rotat -
ed or rep laced but the TPMS was not reset

Ifllilff' ap­
pears after switching the ignition on or whi le
driv ing and the indicator light
RE in the in­
strument cluster blinks for approx imately one
minute and then stays on, there is a system
malfunction .

.8, WARNING
-
- If the tire pressure ind ic a tor ap pears in
the ins trumen t cluster display, one or
more of your tires is significant ly under­
inflated . Reduce yo ur speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures.

216 Tires and wheels
Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 200. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or accidents
could also result.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
page 207. We recom­
mend using these tir es.
Reset tire pressure monitoring system
(Stepl)
Applies to veh icles: w ith tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset in
the menu display.
