2014 AUDI A5 COUPE winter tires

vehicle speed excee ds the set speed by about
3 mph (3 km/h). At the same time, a wa rning
symbo l appears in the d isp lay . The symbol's
appearance might be different in some mod­
e ls.
The speed warning system has two warning thresholds that function independently of
each other and that have somewhat different
pu rposes:
Speed warning 1
You ca n use speed warnin g 1 to set the maxi ­
mum s peed w hile you are driv ing. Th is sett ing
will remain in effect until you t urn off the igni ­
tion, assuming that you have not changed or reset the setting.
The . (USA mo dels) /. (Canada mo dels)
speed warning symbol in the warning 1 dis­
p lay appears when you exceed t he maximum
speed. It goes o ut w hen t he speed fa lls below
the s tored max imum speed.
T he speed warning symbo l wi ll also go out i f
the speed
exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maxim um speed
i s deleted .
Speed warning 2
Storing warn ing 2 is recommended if you al­
ways
want to be reminded of a certa in speed ,
for example when you a re traveling in a coun­
try that has a general maximum speed limi t,
or if you do not want to exceed a spec if ied
speed fo r winter tires.
The . (USA models) /. (Canada models)
speed war ning 2 symbo l appears in the d is ­
p lay w hen you exceed the stored spee d lim it.
Unlike war nin g 1, it will not go out u nti l th e
ve hicl e spee d drops be low the store d spee d

186 Intelligent technology
The all-wheel drive concept is designed fo r
high engine power. Yo ur vehicle is exception ­
ally powerful and has exce llent dr iving charac­
te ristics both under normal driving conditions
and on snow and ice . Always read and follow
safety precautions
c:> ,&. .
Winter t ires
When driving in the winte r, your ve hic le with
a ll-whee l drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea­
son t ires) for improved dr iveability a nd brak­
ing: these t ires must be mounted on
all four
wheels . See also i=>page 237, Winter tires.
Tire chain s
Where tire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
with a ll-wheel drive
c:> page 238, Snow
chains.
Replacing wheels /ti res
Vehicles w ith all -wheel drive must a lways
have tires o f the same size. Also avoid t ires
with d iffe rent tread depths . For details see
page
c:;> page 2 33, 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
therefore best to avoid rough t racks and un­
even terrain as much as possible . Also refe r to
<=;> page 188.
A WARNING
Always adjus t you r d rivi ng to roa d and tr af­
fic co ndition s. Do no t let the e xt ra s afety
a ff orde d by all -whee l dr ive tem pt you in to
taking extra risks .
- Alt hough the all-whee l dr ive is very e f­
f ec tive, a lways remember tha t br aking
ca pacity is limited by t ire traction . Yo u
sho uld the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road s urfaces, be careful not to
dr ive too fast because the front wheels co
uld begin to slide o n top of the water
(aquaplaning). If t his should occur, you
will have no warn ing fr om a s udden in­
crease in eng ine speed as w ith a front­
wh eel drive veh icle . Always dr ive at
speeds wh ich are su ited to the road co n­
di tions -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 wi th a conventiona l ener gy sys tem
is not driven for a long per io d of time, the bat­
te ry is discharged by idling current consumers
(e .g. immobilize r). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine .
Intelligent energy management in your vehi­
cle hand les the dist ribution o f electr ica l ener­
gy. Start ing ability is markedly improved and
t h e life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis contin uously de termines
t h e state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature. This determines the current
state of charge and t he power of t he battery .
Idling current management
Idling current management reduces energy
consumption while t he vehi cle is standing.
With the ign ition sw itched off, it controls the
energy supply to the various electrica l compo­
nen ts. Data from battery diagnos is is cons id­
ered .
Depend ing on the battery's state of charge,
individ ual consumers are gradually turned off ..,.

-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 tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
(D Note
-Please note that summer and winter
tires are designed for the cond itions that
are typ ic al in those seasons. Aud i recom­
mends using w inter t ires du ring the win-
Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items which may be replaced)
of automatic tra nsmission, power steering,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the ratio of the height to the width of
the tire in percent . Numbers of 55 or lower in­
d icate a low sidewall for improved steering re­
sponse and better overall handling on dry
pavement .
Bead
means the pa rt of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Tire s an d wheel s 223
ter months . Low temperatu res signifi­
cantly decrease the elastic ity of summer
t ires, which affects traction and braking
ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, res ulting in permanent
ti re damage that can cause loud drivi ng
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. Th e
surfa ce of the rims does not have suffi­
c ien t cor rosion pro te cti on for this and
c o ul d be pe rmanen tly damaged by road
salt or similar substances. This damage
is not covered by warranty.
Cold tir e inflation pressure
me ans the t ire press ure re commended by the
vehicle manufacturer fo r a tire o f a des igna ted
size that has not bee n driven for more than a
couple of miles (k ilomete rs) at low speeds in
the three hour pe riod before the tire p ress ure
is measured or adjusted.
Curb weight
means the weight o f a motor vehicle with
standard equipment including the maximum
capacity of fuel, o il, and coolant, air cond i­
tion ing and additional weight of optiona l
equipment.
E xtra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single
axle system, measured at the tire-ground in-
ter~ces .

Speed rating (letter code)
means the speed at wh ich a tire is des igned to
be driven for extended periods of t ime . The
ratings range from 93 mph (150 km/h) to
186 mph (298 km/h)
¢page 234. You may
not find this information on all tires because
it is not required by law.
The speed rating letter code, where applica­ b le, is molded on the tire sidewall and indi­
cates the maximum permissible road speeds
¢ &. in Winter tires on page 238.
Tire pressure monitoring system*
means a system that detects when one or
more of a vehicle's tires are underinflated and
illuminates a low tire pressure warn ing te ll­
tale .
Tread
means that port ion of a tire that comes into
contact with the road.
Tread separation
means pulling away of the tread from the tire
carcass .
Treadwear indicators (TWI)
means the projections within the pr incipal
grooves designed to give a visual ind ication of
the degrees of wear of the tread. See
¢
page 232, Tread Wear Indicator (TWI) for
mo re inf ormat ion on measuring tire wear.
Uniform Tire Quality Grading
is a tire information system developed by the
United States National Highway Traffic Safety
Admin istration (N HTSA) that is designed to
help buyers make relative comparisons among
tires . Th e U TQG is not a safety rating and not a
g ua ran tee that a tir e will last for a prescribed
number of mi les (kilometers) or perform in a
certain way. It simply gives tire buyers addi ­
tional information to combine with other con-
Tires and wheels 225
siderations, such as price, brand loyalty and
dealer recommendations. Under UTQG, tires
are graded by the t ire manufacturers in three
areas : treadwear, traction, and temperature
resistance. The UTQG informat ion on the tires,
molded into the sidewalls .
U.S. DOT Tire Identification Number (TIN)
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federa l standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example,
DOT ... 2213 ...
means that the tire was produced in the 22nd
week of 2013. The other numbers are market­
ing codes that may or may not be used by the
tire manufacturer. This information is used to
contact consumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and luggage load plus
150 lbs . (68 k ilograms) times the vehicle's to­
tal seating capacity as listed on the label lo­
cated on the driver's side B -pillar .
Vehicle maximum load on the tire
means that load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is
determined by distributing to each ax le its
share of the curb weight, accessory weight,
and normal occupant weight (distr ibuted in
accordance with table below¢
page 226)
and dividing by two.

234 Tire s and wheel s
contribution to good road ho lding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be perfo rmed by an authorized Audi
dea ler. They are familiar with recommended
proced ures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
Re placing t ires and whe els
Tires sho uld be rep laced at least in pairs and
not individua lly (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 240.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci­
fication as the original equipment or approved
optional tires listed in the table
c:> page 226.
Aud i-approved specification ti res are specially
matched to your vehicle and its load limits,
and can contribute to the important road ho ld­
ing, driving characteristics, and safety of the
vehicle. The table
(c:>page 226) lists spec ifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure labe l located on driver's side
B-pillar
(c:>page 226, fig. 169) lists the speci­
f ications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured.
Federal law requires t ire manufacturers to
p lace standard ized information on the s ide­
wall of all tires
c:> fig. 172 . This information
i dent ifies and describes the fundamental
characterist ics, the quality grade of the tire
and a lso provides a tire ident ificat ion number f
or sa fety standard ce rtification and in case of
a reca ll.
Tire specifications
Knowledge of ti re specificat ions makes it eas­
ier to choose the correct tires. Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
P255 / 35 R1 9 96Y XL
This co nta ins the following information:
P Indicates the t ire is for passenger cars
(where app licab le)
2 55 Nominal tire width in mm of the tire
from sidewall edge to sidewa ll edge. In
general, the larger the number, the wider
the tire
35 Height/w idth ratio in percent (aspect ra-
t io)
R Tire construction: Radial
1 9 Rim diameter code (in inches)
9 6 Load rating code
Y Speed rat ing letter code
X L (or "xl", "EXTRA LOAD", or "RF" Indicates
t h at the t ire is a"Re inforced" or an " Extra
Load " tir e
M+S (or "M/S") Indicates that the tire has
some mud and snow capabi lity
The tires could also have the information of
direction of rotat io n
c:> page 222 .
Tire manufacturing date
The manufact uring date is also indicated on
the tire sidewall (possibly on ly on the
inner
s ide of the wheel) :
"DOT ... 2213 ... "means, for example, that
the tire was produced in the 22nd week of 2013.
Speed rating (letter c ode)
The speed rating letter code on the whee ls in­
dicates the maximum permissible road speeds
c:> & in Winter tires on page 238 .
P up to 93 mph (150 km/h)
Q up to 99 mp h (158 km/h)
R up to 106 mph ( 170 km/h)

236 Tire s and whee ls
- All four wheels must be fitted with radia l
t ires of th e same ty pe, size (r olling c ir­
cumfe rence) and the same tread pattern.
Dr iv in g with different tires reduces veh i­
cle handling and can lead to a loss of
c o ntrol.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat,
increasing stopping d istances and caus­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re eq uipped w ith them
at the factory. The vehicle must have a
chassis des igned for r un flat t ires and a
factory-installed tire press ure monito r­
ing system * that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dea ler or
t ire spec ialist to see if you r vehicle can be
equipped with run flat tires .
If run flat
t ires a re used, they must be insta lled on
all four wheels. M ixing tire types is not
permitted.
(D Note
- For technical reasons, it is not generally
poss ible to use the wheel rims from oth­
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is different from the tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- Never d rive without the valve stem cap.
The v alves co uld get damaged.
@ For the sake of the environment
Dispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicable
on the t ire s ide wall between tread shoulder
and maximum section width
c> page 233,
fig . 172 .
For e xample: Tread wear 200 , Traction AA ,
Temperature A .
All passenger car ti res must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread w ear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions on a specified
government test course.
F o r example, a tire graded 1S0 wo uld wear
one and one ha lf (11/2) times as well on the
government course as a ti re graded 100. ..,_

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 237
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.
Your vehicle is equipped with all wheel drive,
th is w ill improve traction during winter driv­
i ng, even with the standa rd tires . However, we
strong ly recommend that you always equip all
fo ur wheels on you r vehicle wit h corre ct ly fit­
ted winter tires or all-season t ires, when win­
te r road cond itions are expected . This also im ­
proves the veh icle's braking per formance and
reduces stopping dista nces.
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 233.
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 .,.

was manufactured . Please see q page 234,
Speed roting (letter code) for
a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code( ¢
page 225) is
on the side wall of the tire
c::> page 233.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal inj ury to you and your passen­
gers.
A WARNING
=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immed iately .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all whee l
drive tempt you into taking extra r is ks . A l­
ways remember :
- When brak ing , an a ll whee l drive vehicle
hand les in the same way as
a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® Fo r the s ake of the en vironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow chains on your vehicle
c::> @ . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail­
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chai ns for your veh i­
cle or instal ling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in ­
structions provided by the snow chain manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con ­
tact with the whee l rim, can scratch or
damage it . Therefore, make sure that the
snow chains are s uitably covered. Check
the pos ition of the snow chains after
