2013 AUDI RS5 CABRIOLET ECU

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 266.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 228, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •

Tire repair
General and safety pointers
Tire repair is intended only for temporary,
short-term use.
F ig . 1 9 2 Tire damage fo r wh ich the Tire Mob ility Sys­
tem is not suited
Your vehicle is equipped with a tire repa ir k it,
the
Tir e Mobility Sy stem (TMS ).
In the event of a tire failure, the TM S is in the
luggage compartment under the floor. It con­
s ists of the tire sealant and an electric air
pump .
Using
TM S, tire damage caused by foreign
bodies up to about
0.1 6 inch (4 mm ) in diam­
eter can be sea led reliably.
The foreign object must stay in the tire .
The tire sealant must not be used:
-for cu ts or punctures in t he tire w hich a re
large r th an 0. 16 inc h (4 mm) <=>fig. 192

rod into the opening on the handwheel. Turn
the rod left or r ight to secure it.
• Continue raising the jack with the rod unt il
the wheel lifts off the ground slightly.
Position the vehicle jack
only under the desig­
nated lifting points on the si ll
<=>fig. 196.
There is exactly one location for each wheel.
The jack must not be positioned at any other
location <=> .&. <=>CD .
Soft ground under the jack can cause the ve­
hicle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if
necessary. Use a non -slip surface such as a
rubber mat on a
slippery surface such as tile .
.&, WARNING
-You or your passengers could be inju red
while changing a wheel if you do not fo l­
low these safety precautions:
- Position the vehicle jack only at the designated lifting points and align the
jack. Otherwise, the vehicle jack could
slip and cause an injury if it does not
have sufficient hold on the vehicle.
-A soft or unstable surface under the jack may cause the vehicle to slip off
the jack. Always provide a firm base for
the jack on the ground. If ne cessa ry,
us e a sturdy board under the jack.
- On hard, slippery su rface (such as tiles)
u se a rubber mat or similar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passengers:
- Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the veh icle and
well away from t he road and traffic.
- Make sure jack position is correct, ad­
ju st as necessary and then continue to
