2013 AUDI TT brake fluid

-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.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.
Fig. 139 Engin e compart ment: cover on th e br ake fluid
re se rvoir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c::> .&. in Working in the engine compart­
ment on page 180.
~ Read the brake fluid level from the brake
fluid reservoir
c::> page 182, fig. 134 . The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located behind the
rear partition of the engine compartment on
the left side
c::> page 182.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads. This is not cause for alarm.
i,,.

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

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-

204 Tire s and wheel s
-If the tire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not handle well.
- If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without valve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels a re securely
mounted on the valve.
@ For the sake of the environment
Underinf lated tires will a lso increase the
fue l cons umption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can c arry.
A vehicle that is overloaded w ill not h andle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and eve ryth ing in and on the vehicle . These
l oad limits a re tech nica lly refe rred to as the
ve hicl e's
Gros s Vehicl e W eight Rat ing
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory installed accesso ries , a fu ll
tank of f uel , oi l, coo lant and othe r fluids plus
maximum load. The maxim um load includes
the number o f passengers that the vehi cle is
intended to carry ("seating capacity") with an
assumed weig ht of 150 lbs (68 kg) for each
passenger at a designated seating position and the total weight of any luggage
in the ve ­
hicle .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 4 seat ing
positions, 2 in the front and 2 in the rear fo r
total seat ing capac ity of 4. Each seating posi­
t ion has a safety be lt c>
page 100 , Safety
bel ts.
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label on your Aud i also lists
the max imum combi ned weig ht of all of the
occupants and luggage or other cargo t hat
t h e vehi cle can carry . Fo r th e lo cat ion of the
la bel c>page200,

_& WARNING ~
Overloading a vehicle can c ause loss o f ve-
h icle cont ro l, a c rash or other accident, se ­
rious pe rsonal injury, and even death.
- Ca rrying more we igh t tha n your veh icle
was des igned to carry wi ll prevent the
veh icle from handling proper ly and in­
crease the risk of the loss of ve hicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance .
- Tires on a vehicle that has been over load­
ed can fail s uddenly , incl uding a blowout
a nd sudden deflation, causing loss of
control and a crash .

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury !
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning " and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
