2014 AUDI TT ROADSTER steering wheel

A WARNING
-=
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position.
- Always make sure that the
PASSENGER
AIR BAG OFF light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk " re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates. In addition, the system
Child Safety 131
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list­
ed in the Standard .
Even though your vehicle is equipped with an
Advanced Airbag system, a child should al­
ways ride in the seat properly restrained for
its age and size . The airbag on the passenger
side makes the front seat a potentially dan­
gerous place for a child to ride. The front seat
is not the safest place for a child in a forward­
facing child safety seat .
It can be a very dan­
gerous place for an infant or a larger child in a
rearward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re­
straints and for the different models of the
same kind of child restraint offered by child restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air­
bag System. When a child restraint is being
used on the front passenger seat with a

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle go ing in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works togethe r with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

gear or lower driving range. Do no t ride
t h e brakes or hold the pedal down too
long or too often. This cou ld cause the
bra kes to get hot and dimin ish braking
efficiency .
- Do no t "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the brakes to
overheat, prematu re wear and inc reased
stopp ing distan ce.
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving i n heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be red uced . In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake d iscs and pads w it h a few cautious
brake appli cat ions.
- If you damage the fro nt spo iler, or if you
ins tall a different spoiler, be su re the air
flow to the fron t bra kes is not o bstr uct­
ed. O therwise the brake system co uld
overheat reducing the effectiveness of
the entire brake system.
- F ailure o f one bra ke c ircuit will impair
the b raking capability resulting in an in­
creased stopp ing distance . Avoid driv ing
the vehicle and have it towed to the near­
est Aud i dea le r o r qualified workshop.
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not working, t he
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance . Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assi st is electronically
matched to vehicle speed .
T he power steering system assists the driver
so that he can steer the vehicle with reduced
physical effor t.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn.
A WARNING
If the system develops a problem , you
must seek qualified profess iona l assis ­
tance .
(D Note
-
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onge r proportionate to the vehicle speed .
This is most not icea ble whe n tu rni ng the
s tee ring w heel a t low speeds (fo r example
when pa rking), -more effort w ill be re­
q uired than us ua l.
- Be aware o f the diffe rent than usual
steering response and adjust your steer ­
ing force acco rdingly.
- Have the problem checked and set right
by an autho rize d Aud i dealer as soon as
possible.
- If a s teer ing mal func tion occurs, this is
signa led wit h the

lights and a warning tone, see.
(D Tips
- If the powe r stee ring system sho uld fai l,
or if the engine is not ru nning (fo r exam­
ple, whi le being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.

tioni ng properly, contact your a uthorized
Audi dealer immediate ly.
Driving with your
quattro
App lies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gene ral inform ati on
With all-wheel drive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving sty le and the road
conditions at the t ime. See a lso
r=;, page 142.
The all-wheel drive concept is designed for
h igh engine power. Your vehicle is exception­
ally powerful and has excellent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions
c::;, ,&. .
Winter t ire s
When drivi ng in the w inter, your ve hicle w ith
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter t ires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
w heel s.
See also c::;, page 196, Winter tires.
Snow chains
Where t ire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
w ith a ll-wheel d rive
c::;, page 19 7, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid t i res
with d iffe ren t tread depths. For details see
page
c::;, page 192 , New tires and replacing
tires and wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
Int ellig ent technolog y 147
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
r=;, page 151.
_& WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire tract ion. You
should t herefore not d rive at excessive
speeds on icy or slippe ry road s urfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If th is should occur, yo u
wi ll have no warning from a s udden in ­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventiona l energy system
is not d rive n for a long per iod of t ime, the bat­
te ry is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine.
Intellige nt energy managemen t in your vehi­
cle handles the dis tribution o f electrica l ene r­
gy. Starting ability is marked ly improved and
the life of the battery is extended .

182 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u 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 t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

Tires and wheels 191
Rotating tires for more even wear
For all four tires on your ve hicl e to have the
same service life, we recomme nd that the
front and rear tires are rotated according to
the tire manufacturer 's suggested tire rota­
tion inte rvals. Please remember the follow ­
ing :
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Warranty & Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufactu rer 's suggested
tire rotation intervals .
- Vehicles w ith front-wheel dr ive exper ience
more tread wear on the front wheels com­
pared to all -wheel d rive (quattro) .
- Please rotate tires as shown
c::> fig. 141.
-Extra care must be taken when rotat ing di-
rection-specific tires
c::> page 212.
Wheel balancing
T he wheels on new veh icles are balanced .
However, various situations during everyday
driving can cause them to become unba l­
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, s uspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Inco rrect wheel alignm ent
Incorrect wheel alignment can cause exces­
sive tire wear, impai ring the safety of the vehi­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
all -wheel drive
Vehicles wi th quattro must always have tires
of the same size, construction and tread type. For details see
c::> page 147.

When it i s not po ssibl e to co ntinu e
d riv ing, even with run-fl at ti res?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire P ressure 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 dr iving if severe vibration
occurs or if the tire starts to smoke because
the tire is runn ing 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
vehicle damage that can lead to loss of ve­
hicle control, a crash and serious personal
injury.
- Run-flat tires can only be used with spe­
c ial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ss ure Mon itor ing System.
- Always inspect a tire that has lost air to
make su re it is safe to drive w ith the t ire
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 t ire 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 author ized Audi dealer or
qualified wo rkshop must reprogram the
control module.
Tire s an d wheel s 203
@ Note
Run-f lat ti res have special characteristics
and requirements, that are very different
from convent ional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional whee l rims .
(D Tips
- If you are not able to cont inue driving
w ith run-flat tires, please seek professio­
nal ass istance.
- Please contact your authorized Audi
dealer or Aud i of America, Inc . if you
have questions about t ires and rims.
Driving with run-flat tires
Applies to veh icles: w it h Run -flat t ires
Handling characteristics change when tire
pressure is low.
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
corner ing 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 whe n oper ­
at ing a veh icle on run-flat tires when t ire pres­
s u re is low o r the tire(s) is flat:
" The Electronic Stabilization Contro l (E SC)
must be switched on.
" Never drive fas ter than 50 mph (80 km/h)
q .&_ .
"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
braking maneuvers.
" Reduce your speed in plenty of t ime before
intersections, curves and other places where
you may have to react quickly .
