2015 AUDI TT ROADSTER ABS

@ 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.

cal know ledge. P lease contact an Audi

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 41 Disp lay : under in fla 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
[I] and a
message
'* fig. 141. 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 199
al and fu ll load pressure) or after changing o r
replacing a tire on your vehicle '*
page 200.
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 184 .
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
¢ page 200.
Warning symbo ls
[I] Loss of press ure in at least one tire'*& .
Check the tire or tires and rep lace or repa ir if
necessary . The indicator light
[I] in the instru ­
ment cluster a lso i lluminates
¢ page 13.
Check/correct the press ures of all four tires
and reset TPMS in the menu display .
mm (T ire Pressure Monitoring System) Ti re
pre ssure! System malfun ction . Ifll appears
after switching the ign it ion on or while dr iving
and the indicator light
[I] in the instrument
clus ter blinks fo r approximately one m inute
and then stays on, there is a system malfunc ­
tion . Attemp t to store the correct t ire pres­
su re '*
page 200 . If the ind icator light does
not turn off or if i t turns on shortly thereafte r,
immedia tely drive your vehicle to an au thor­
ized Audi dea ler or author ized repai r fac ility to
have the malfunction corrected .
A WARNING
=
-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is significant ly under­
inflated. Reduce your speed immediately
and avoid any hard steer ing or b rak ing
maneuvers. Stop as soon as possib le and
check the tires and their pressu res . In­
flate the tire pressure to the prope r pres-
sure as indicated on the vehicle's tire .,..
