2015 AUDI RS5 CABRIOLET warning

238 Tire s and whee ls
be fitted over the whee l bolts. These are
avai lab le from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury .
- Snow chains are available in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving with snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions .
- Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
chains down unnecessar ily .
- Snow chains, wh ic h come into d irect con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitab ly covered . Check
the position of the snow chains after
driv ing a few yards and correct if neces­
sary. Follow the i nstr uctions from the
snow chain manufacturer when doing so.
(D Tips
Where s now cha ins a re mandatory oncer­
tain roads, this norma lly also applies to
vehicles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
corr ect torque.
The design of whee l bolts is ma tched to the
factory insta lled r ims. If d ifferent rims are fit­
ted, the correct wheel bo lts with the r ight
l ength and correctly shaped bolt heads must
be used . This ensures that wheels are fitted
secu re ly and that the b rake system functions
correctly . In certain circumstances, you may not use
whee l bolts from a different vehicle -even if it
is the same mode l¢
page 266 .
A WARNING "--
Improperly t ightened or ma inta ined whee l
bo lts can become loose causing loss of
control, a col lision and serious pe rsonal i n­
jury .
- Always keep the wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never g rease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driv ing if g reased o r
oiled, even if t igh tened to the specified
torque.
- On ly use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tighten ing tor­
que of the whee l bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
Q) Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi ­
ble with a to rque wrenc h - preferably by an
autho rized Audi dea le r or qualified wor k­
shop .
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l ..,.

24 0 T ire s and wheel s
According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears
Applies to vehicles: wit h tire press ure mo nitor ing 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 .

U sing the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum ­
ference and vib ration characteristics of the in­
dividua l tires.
If the pressure decreases in one
or more t ires, this is indicated in the instru­
ment cluster with a

signific antly under-inflated tire ca uses
the tire to overhea t and can lead to tire
f ailure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures . You must
check the t ire pressures regular ly.
- Under certain cond itions (such as a spor ­
ty driving style, w inter condit ions or un­

.,. Move the se lector lever to the P pos ition
.,. Check whether a repair using the Tire Mobili­
ty System is possib le ¢
page 242.
.,. Have a ll passengers leave the vehicle and
stay away from the danger zone~_&..
.,. Take the seala nt bottle and the electric air
pump from the luggage compartment under
the floor ¢
page 242.
.,. Remove the "max. SO mph" (80 km/h) stic k­
er from the sealant bottle and affix i t to the
ins trumen t cluster in the drive r's view.
Filling a tire
.,. Shake the bott le thoro ughly before filling. ..,

24 4 What do I do no w?
• Screw the accompanying filling hose com ­
pletely onto the bottle. This breaks through
the fo il seal automat ica lly at the connec­
t ion.
• Remove the valve cap from the tire valve and
unscrew the valve insert us ing the accompa ­
nying valve insert tool
q fig . 190 .
• Lay the valve insert on a clean surface .
• Remove the sealing p lug from the filling
hose and connect the hose to the t ire va lve.
• Hold the bottle with the bottom fac ing up­
ward and empty the entire contents into the
tire.
• Then pu ll out the hose and screw the valve
insert tightly back into the tire valve.
Inflating a ti re
• Screw the fi lling hose for the electric air
pump onto the tire valve and insert the con ­
nector into the cigarette lighter .
• Inf late the tire between 2.0 and 2.S bar and
read the pressure from the gauge.
• If this tire pressure is not reached, drive
your vehicle approximately 10 meters for ­
ward or backward so that the sealant can be redistr ibuted i nside the tire.
If at th is time
the required air pressure still cannot be reached, the t ire is too bad ly damaged and
cannot be repaired with the tire sea lant.
Final check
• After dr iving for about 10 minutes, stop and
check the t ire pressure .
• If tire pressure is less than 1.3 bar, the ti re
is too seve rely damaged. Do not cont in u e to
drive . Seek pro fessional assistance.
8_ WARNING
- Turn on the eme rgency flashers and set
up the emergency triangle if you have
flat tire while in moving traff ic. This is
for your protection and the for the safety
of other d rivers .
- Have all passengers leave the vehicle and
stay away from the danger zone (fo r ex­
ample, beh ind a guard rail). -
Read and follow the manufacturer's safe­
ty precautions on the compressor and in
the instructions on the bottle of sealant!
- If a tire pressure of 2.0 bar cannot
reached after inflating for six minutes,
then the t ire is too severely damaged. Do
not continue driving!
- Obta in qualified help if it is not possible
to perform the repair with the tire seal­
ant.
- If the tire pressure is less than 1.3 bar
after 10 m inutes of driv ing, then the the
tire is too seve rely damaged . Do not con­
tinue dr iving. Seek profess iona l assis­
tance.
Q) Note
Particular care is necessary if you are mak­
i ng a tire repa ir on a steep incl ine .
@ Tips
-Do not operate the electric air pump for
more than 6 minutes without stopping,
otherwise it can overheat . When the a ir
pump has cooled down, you can continue
t o u se i t.
- If sealant has spilled out, let it dry and
then you can remove it by peeling it away
like a foil.
- Rememb er to obtain a new bott le of
sealant from yo ur autho rized Aud i deale r
after repairing a tire. After this, the func­
tionality of the tire repair set is resto red.
- Obey all laws.
