2015 AUDI TT ROADSTER ignition

@ For the sake of the environment
Because of the problem of proper disposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Your vehicle is equipped with a special bat­
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re­
p laced w ith an original equipment battery .
Under normal operati ng conditions, the bat­
tery is
maint enan ce -fre e.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than
5 years.
Di sconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are d isconnected. These functions have
to be re learned after the battery terminals are
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lectr ica l system when absolutely necessary
for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo ­
nents are gradually cut back o r switched off .
This reduces energy consumption and main­
tains sta rting capab ility over a longer per iod
c::> page 146. Some of the convenience func­
tions may not operate, s uch as the interior
lights or power seat adjustment. The conven ­
ience functions will be avai lab le again when
you switch on the ignition and start the en­ g ine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as temperatures d rop. This
is because more powe r is also consumed while
Checkin g and fillin g 175
starting, and the headlights, rear window de ­
fogger, etc ., are used more often .
Avoid unnecess ary powe r consumpt io n, p ar­
t icu lar ly in city traffic o r when traveling only
sho rt distances. Let your authorized A udi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::> page 178. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer .
Replacing battery
The new battery must ha ve the same capaci ­
ty, voltage (12 volts), amperage, construction
and plug sea ling, as the original battery. Spec­
ifications are listed o n the battery housing.
Batter ies spec ia lly developed by Audi fulfill
the maintenance, outp ut, and safety require­
ments.
When installing the battery, make sure the ig­ nition and a ll electrical consumers are switch ­
ed off
c::> (D .
We recommend that you use maintenance­
free or
cycle -res istant /leak-proof batter ies
accord ing to the standards TL 825 06 (from
Apr il 2008) and VW 7 50 73 (from Ap ril
2010).
Rep lacing the battery should be carried by a
qualified workshop. Please fo llow the instruc ­
tions on the battery cover.
([) Note
-All work on the battery requ ires techn i­
cal know ledge. P lease contact an Audi

-Do not interchange the positive and neg­
ative cables .
- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca ­
ble .
- Before performing any work on the elec ­
trical system , switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery , switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dis­
charged battery can freeze over at 32 °F
(0 °C) .
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat ­
tery.
- Never use batteries which are damaged.
Danger of explosion! Always replace a
damaged battery.
Checking and filling 177
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related ac­ cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc ­
tive problems . Wash hands after han­
dling.
Q) Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise , you will
damage electronic components in the
electrical system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Checking the battery acid level on magic
eye batteries*
The battery acid level in the battery can be
checked through the clear inspection window .
Fig. 134 Lugg age compar tme nt: Battery w ith mag ic
e ye .
On top of the battery, there is a round "win­
dow". This window (magic eye) changes color
as the battery charge and acid level change.
.,. Read and heed all WARNINGS
~.&_ in
Working on the battery on page 176
.. Read the acid level from the window on the
battery ~

@ Tips
-Before resetting the TPMS, the current
pressures of
all four tires must corre­
spond t o the specified va lues. Adjust the
tire pressu re and reset the pressure in
the tire pressure mon itor ing system ac­
cord ing to the load yo u are carry ing
<=> pag e 184.
- Do not store the tire pressure if there are
snow cha ins on the tire . Othe rwise, a
system malfunct ion may occ ur.

Run-flat ti res
Introduction
Applies to vehicles: with Run -f lat tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the tires run-flat ca­
pability if tire pressure is lost .
We recommend that r un-flat tires on ly be
m ounted on vehicles that were orig inally
equipped with these special tires at t he facto­
ry and have a Tire Pressure Moni toring Sys­
tem .
Run-flat tires can be identified by the letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
norma l to run- flat tires, you must b uy the
special rims required for run-flat tires, and the
T ire Pressure Monitor ing System must be re­
programmed by an authorized Aud i dealer o r
other qualified worksho p .
What do run-fl at tires do?
These special tires have r un-flat capabilities
that help keep you moving if a t ire loses pres­
sure and goes flat . Under favorable conditions
ti res can be dr iven
at least 30 miles (50 km) ,
but you mus t not dr ive faster than 50 mph Ill-

compartment for the t ime being .
~ Start driv ing right away so that the sealant
is dist ributed in the tire.
.&_ WARNING
- Follow the manufacturer 's safe ty inst ru c­
tions on the de cal for the ai r pump and
the sealan t bottle .
- If a tire pressure of 1.8 bar cannot be
achieved after pumping for 5 minutes,
the ti re is too severe ly damaged. Do not
continue to drive .
- Seek pro fessional assistance if it is not
possible to repa ir the tire with the t ire
sealant.
(D Tips
- Do not opera te the elec tric air pump fo r
more than 6 minutes without stopping,
otherwise it can overheat . When the ai r
pump has coo led down, you can continue
to use it.
- If sea lant has escaped, allow it to dry,
then yo u can peel it off.
Final check
App lies to vehicles : wi th Tire Mobility Sys tem
After d riv ing for a short d istance , tir e
pressure must be checked
~ After driving for about 10 mi nutes, stop and
check the tire pressure .
~ If tire pressu re is st ill at least 1.3 bar, in­
flate the tire to specified press ure (see dr iv­
er's side B-pillar), drive to the next repa ir
shop and have the tire and the sealant bot­
tle replaced.
~ If tire pressu re is less than 1.3 bar, the t ire
is too severely damaged. Do not continue to
