2014 AUDI TT ROADSTER ABS

176 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than S years .
Disconn ect ing the battery terminals
Some veh icle functions (power w indow regu­
lators, for example) are lost if the battery ter ­
minals are disconnected . 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
electr ical system when absolutely necessary
for repairs .
V ehicles not dri ven 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 or switched off .
This reduces energy consumption and main­ tains starting capab ility over a longer period
c:::>
page 147. Some of the convenience func­
tions may not operate, suc h as the inte rior
l ights or power seat adjustme nt. The conven­
i ence functions wi ll be ava ilable aga in whe n
you switch on the ignition and start the en ­
gine.
Winter operati on
During the winter months, batte ry capacity
tends to decrease as tempe ratu res d rop . This
is because more powe r is also consumed while
start ing , and the headlights, rea r window de ­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when t rave ling on ly
short distances. Let you r authorized Aud i
dea ler check the capacity of the vehicle bat ­
tery before winter sets inc:::>
page 179 . A we ll
charged battery w ill not only prevent starting
prob lems when the weather is cold, but will
a lso last longer .
Replacing battery
The new battery must have the same capaci­
ty, vo ltage (12 volts), amperage, construction
and p lug sealing, as the origina l battery. Spec­
if ications are listed on the battery housing.
Batteries specially developed by Audi fulfill the maintenance, outp
ut, and safety require­
ments .
When install ing the battery, m ake su re the ig­
ni tion and a ll ele ct rical consumers are switch ­
ed off
c:::> (i) .
We recommend that you use maintenance­
free or
cy cle-re si stant /leak -proof b atter ies
accord ing to the s tanda rds TL 825 06 (from
Apri l 2008) and VW 7 SO 73 (from April
2010) .
Rep lac ing the bat tery shou ld be car ried by a
qualified wo rkshop. Please fo llow the instruc­
tions on the battery cover .
(D Note
- All wo rk on the ba tte ry req uire s techn i­
c al know ledge . Please con ta ct an Aud i
dealership o r another authorized faci lity
for questions abo ut the batte ry -danger
o f 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 l uggage com­
partment cannot leak, because the elec­
tro lyte for this battery is absorbed into a
special glass mat. This leak-proof battery
must not be replace with a convent ional
battery.
- Make sure the ventilation hose on the
side of the battery is connected, other­
w ise fumes or battery ac id can leak out .
- Batte ry holder and termina ls always
have to be secured correctly .
- Before all work on the battery follow the
warnings be low c:::> .&. in Working on the
battery on page 177.
@ For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author­
iz ed Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must a lways be disposed o f prop-
erly in compliance wi th al l envi ronmental ..,.

200 Tires and wheels
remain continuo usly illuminated . This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning properly . Always check the TPMS malfunction
tellta le after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
placement or alternate 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. 143 Display : underi nflat io n warn ing
Using the ABS sensors, the tire pressure moni­
toring sys tem compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment clus ter with a warning symbo l
ail and a
message<>
fig. 143. The dr iver message in the
display goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on ­
l y one tire is affected, the display will indicate
its pos ition.
The tire press ure monitoring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti- al and fu
ll load pressure) or after changing or
replacing a tire on your vehicle<>
page 201.
The TPMS indicator only mon itors the t ire
pressure that you have previously stored . You
can find the recommended tire pressures for
your vehicle on the label on the driver's door
pillar
¢ page 185.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset
¢ page 201.
Warning symbols
ail Loss of pressure in at least one tire¢& .
Check the tire or tires and replace or repa ir if
necessary . The indicator light

ment cluster also illuminates
<>page 13.
Check/correct the pressures of all four tires
and reset TPMS in the menu display .

ap­
pears after switching the ignition on or while
driv ing and the indicator lig ht

strument cluster blinks for approx ima tely one
minute and then stays on, there is a system
malfunction .
At tempt to store the correct tire pressure
¢ page 201. Ifthe indicator light does not
turn
off or if it turns on shortly thereafter, im ­
med iate ly drive your vehicle to an author ized
Audi dealer or author ized repair facility to
have the malfunction corrected.
_&. WARNING
-
- If the tire pressure indicat or appears in
the instrument cluster display, one or
more of your tires is significant ly under­
inflated . Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures.
IJJ,,

Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 185. 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 mainta ining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, wint er conditions or un­
paved roads), the pressure monitor indi­
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 vehicle 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 tires with the "AO" or "RO" identification on the
tire sidewall¢
page 192. We recom­
mend using these tires.
