2014 AUDI A5 CABRIOLET Owners Manual

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 266.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 239
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop .
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details .
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 228 , Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.

24 0 T ire s and wheel s
In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ic h could event u­
ally cause t ire fail ure.
If you be lieve that a
ti re may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more qui ck ly than oth­
ers.
- Please a lso remembe r that, whi le these t ires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
R educed p erf ormance in winter /cold
s ea son condit ions
A ll tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance and handling . They are not suitable
for cold, snowy or icy weather cond it ions.
If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offe r better traction under
those cond it ions . We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monito ring system
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and in­
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in­
flat io n pressu re label, you shou ld dete rmine
the p roper t ire infla tion p ressure fo r those
t ir es) .
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system ( TPM S) that illum inates a low ti re
pressure te lltale whe n one or more o f you r
tires is significant ly under -inflated . Acco rding­
ly, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al ­
so reduces fuel eff ic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respo nsibility to maintain co rrect tire
pressure, even if under -inflation has not
reached the leve l to tr igger illuminat ion of the
T PMS low tire p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate when
the sys tem is not operating properly . T he
T PMS ma lfunction indicator is combined with
the low tire pressure te lltale. Whe n the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then
rema in con tinuously illum inated . T hi s se­
quence will continue upon subsequent vehicle
start-ups as long as t he malfunct ion exists . .,.

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 whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacemen t 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.
Fig. 187 Display: underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indica ted in the instru­
ment clus ter with a
RE wa rning symbol and a
message¢
fig. 187 . The driver message in the
disp lay goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The ti re pressu re monitoring system must be
reset via radio or MMI* each time the pres ­
sures are adjusted (e.g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢
page 242 . The TPMS indicator only moni­
tors the tire pressure that you have prev iously

stored . You can find the recommended t ire
pressures for yo ur vehicle on the label on driv ­
er's side 8-pillar ¢

T ire tread circum ference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- t he t ire p ress ure in one or more tires is too
low,
- t he t ire has s tructural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

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 raking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In­

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 ma inta ining
the correct tire pressures. You must
check the t ire pressures regularly .
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
-Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registrat ion becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may resul t in a system
malfunction.
- The tire pressure monitoring system on
you r Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall¢
page 233 . We recom­
mend using these t ires .
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
radio or MMI*.
11> Before resett ing the TPMS, the cu rrent pres­
sures of all fou r tires m ust correspond to
the specified val ues . Adjust the tire pressure
and reset the pressure i n the tire press ure

24 4 What do I do no w?
There are some restrictions on the use of the
compact spare tire. The compact spare tire
has been des igned specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare tire from another type of vehicle.
Sno w cha in s
For technical reasons, the use of snow chains
on the compact spare tire is
n ot permitted .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel w ith
tire instead of a rear tire. Install the snow
chains on the rear tire and use it to rep lace
the defective front tire.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
t reme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire.
- After mounting the compact spare tire, the tire pressu re must be checked as
soon as poss ible. The tire pressure of the
c ompac t spare tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than 50 mph (80 km/
h). You risk having an acc ident.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . Yo u risk hav­
ing an acc iden t.
- Never drive us ing more than one spare
wheel and tire. You risk having an acci­
dent.
- No rma l summer or winte r tires m ust not
be mounted on the compact spare whee l
rim.
- F or te chni cal reasons, the use of ti re
chains on the spare tire is not permitte d.
If it is necessary to drive with tire chains,
the spare whee l must be mounted on the
front axle in the event o f a f lat in a rear tire. The new
ly available front wheel
must then be installed in place of the
rear whee l with the flat tire. Installing
the t ire cha in before mounting the whee l
and tire is recommended .
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the spa re tire or jack and
too ls in the passenger compa rtment.
