2013 AUDI RS5 CABRIOLET low oil pressure

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

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 . .., •
•

~ Screw the accompanying filling hose com­
pletely onto the bottle. This breaks through
the foi l seal automat ically at the connec­
t ion.
~ Remove the valve cap from the tire valve and
unsc rew the valve insert us ing the accompa ­
nying valve insert tool¢
fig. 193 .
~ Lay the valve insert on a clean surface .
~ Remove the sealing plug from the filling
hose and connect the hose to the tire v alve.
~ Hold the bottle with the bottom fac ing up ­
ward and emp ty 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 tir e
~ Screw the filling hose for the electric a ir
pump onto the tire valve and insert the con­
nector into the cigarette lighter .
~ Inflate the t ire between 2.0 and 2.5 bar and
read the pressure from the gauge.
~ If this tire pressure is not reached, drive
your vehicle approximate ly 10 meters for ­
ward or backwa rd so that the sealant can be
redistributed i nside the tire . If at th is time
the req uired air p ressu re still cannot be
reached, the t ire is too badly damaged and
cannot be repa ired with the tire sea lant.
Final check
~ After dr iving for about 10 minutes, stop and
chec k the t ire p ressure.
~ If tire pressure is less than 1.3 bar, the tire
is too seve rely d amaged. Do not contin ue to
dr ive . Seek pro fessional assistance.
& WARNING
- Turn on the emergency flashers and set
up the emergency triangle if you have
flat tire while in mov ing traffic. This is
for your protection and the for the safety
of other drivers.
- Have all passengers leave the vehicle and
stay away from the danger zone (for ex­
amp le, beh ind a guard rail) .
What do I do now? 245
-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 inf lating for six minutes,
then the tire is too severely damaged. Do not continue driving!
- Obta in qua lified help if it is not possible
to pe rform the repair wit h the t ire seal­
a nt.
- 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 .
(D Note
Particular care is necessary if you are mak­
i ng a tire repa ir on a steep incl ine .
(D Tips
-Do not operate the electric air pump for
more than 6 minutes without stopping,
otherwise it can over heat. When the a ir
pump has coo led down, you can continue
t o use it.
- If sea lant has spilled out, let it dry and
then you can remove it by peeling it away
like a foil.
- Remember to obtain a new bott le of
sealant from yo ur autho rized Aud i dea le r
afte r repairing a tire. After this, the func­
tionality of the tire repa ir set is restored.
- Obey all laws.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger 's safety when chang­
ing a wheel.
~ After you experience a tire failure, pull the
car we ll away from moving traffic and try to
reach
le vel ground before you stop ¢ ,&..
~ All passengers should lea ve the car and
move to a safe location (for instance, behind
the guardrail) ¢
