air condition AUDI TT ROADSTER 2015 Owner's Manual

The relative perform a nee of ti res depends
upon the actua l conditions of their use, how ­
ever, and may depart sign ificantly from the
norm due to var iat ions in dr iving habits, serv­
ice practices and differences in road character­
istics and climate .
Trac tion
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢,&. .
Temp erature
The temperature grades are A (the h ighest),
B, and
C, representing the t ire's resistance to
the generat ion of heat and its ability to dissi ­
pate heat when tested under controlled condi­
tions on a specified i ndoor laboratory test
wheel.
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa ilu re ¢ ,&. .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet
u nder the Federa l Moto r Veh icle Safety Stand­
a rd No.
1 09. G rades Band A represent h igher
l eve ls of perfo rmance on the laboratory tes t
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this ti re is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering, hydrop lan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es­
tablished for a t ire that is p roperly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
-
Tire s an d wheel s 195
separately or in combinat ion, can ca use
heat bui ldup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter o r "snow" tires, those
with very deeply cut tread. These tires should
o nly be used in pairs and be installed o n all
four wheels . Make sure you purchase snow
t ires that are the same size and construction
type as the other tires on you r vehicle.
If your vehicle is equipped w ith all-whee l
drive*, th is w ill improve traction during winter
driv ing, even with the standa rd tires. Howev­
er, we stro ngly recommend that you always
equip all fou r whee ls o n your veh icle w ith co r­
rect ly fi tted winter tires o r all-season tires,
when w inter road condit ions are expe cted .
T his also improves the veh icle's b raking per ­
formance and reduces stopping distances.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur wheels .
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire size s. Use
o nly rad ial w inter t ires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm) .
Only drive w ith w inter t ires under w inter con­
dit ions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
whee l
¢page 191.
Please a lways remember that winter tires may
have a lowe r speed rating than the tires o rigi -
nally installed on your vehicle at the time it .,.

pressure label¢ page 184. 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, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes inval id
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
cou ld also resu lt.
- 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 may
stop working when there is an ESC mal ­
funct ion .
- 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" identif ication on the
tire sidewall ¢
page 191. We recom­
mend using these tires.

tires .
When it is not possible to continue
driving, even with run-flat tires?
- If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire Pressure Monitoring System does
not work .
-If the tire has been severely damaged, in a
crash, for example. The tread can separate
from a damaged tire as the whee l turns , and
hit parts of the vehicle , such as the fuel tank
filler neck, fuel lines or brake lines.
- Do not continue driving if severe vibration
occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat t ires can cause
veh icle damage that can lead to loss of ve­
hicle control, a crash and serious pe rsonal
injury.
- Run-flat tires can only be used with spe­ cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire
P re­
ssure Mon itor ing System.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision .
- Never drive with run-flat tires if heat
build-up causes the tire to give off
smoke .
- Never drive with run-flat tires if the vehi­
cle shakes or v ibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
- If you switch between standard and run ­
flat tires, an authorized Audi dealer or qualified workshop must reprogram the
control module .
-
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to cont inue driving
with run-flat tires, please seek professio­
nal assistance.
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a vehicle handles, particularly when
cornering and braking. The handling charac­
teristics of run-flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take specia l precautions when ope r­
at ing a vehicle on run-flat tires when tire pres­
sure is low o r the tire(s) is flat:
.,. The Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than 50 mph (80 km/h)
¢&_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers.
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react quickly.
Please see :
¢ page 202, When it is not possi­
ble to continue driving, even with run-flat
tires?

Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pu lling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving character istics by pulling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation.
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run -flat mode.
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
maneuvers.

Replacing run-flat tires and rims
App lies to veh icles : w it h Run -flat t ires
Your vehicle was especially designed to use
special run-flat tires.
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run-flat tires. Mounting
special run-flat tires on standard wheels will not work and w ill not prov ide the advantages
fo the ru n-falt feature . Never use spec ial run­
flat tires on standa rd wheel rims.
After dr iving with a tire i n the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by a n authorized Audi
dealer. Tires that have been driven in the run­
f lat mode must be rep laced .
A WARNING
-Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode .
- Tires that have been dr iven in the run­
f lat mode must be replaced.
