2014 AUDI A5 COUPE ECU

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 . ..,.

(D Tips
-When mount ing tires with unidirectional
tread design
make sure the tread pat ­
tern is po inted the right way
c::> page 249. Iii>

-The wheel bol ts should be clean and easy
to tu rn. Check for d irt and corrosion on
t h e mat ing s urfaces of both the whee l
and t he hu b. Remove a ll dirt from these
su rfaces before remo unt ing t he wheel.
- Do n ot use the hexagonal socket in the
screwdriver ha ndle to loosen or tig hten
t h e wheel bo lts .
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a t read patte rn
i ntended for use in a specific direction, please
n ot e th e follow ing:
- The direction of rotation is ma rked by an
ar­
row on the s ide of the t ire .
-If the spare t i re has to be installed in the in­
correct di rection, use the spare tire only
temporar ily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with r ega rd to aquaplani ng, noise and
wea r.
- We recommend that you pay particular at ­
tent io n t o this fact du ring wet weathe r and
t h at you adjus t your spee d to matc h road
cond itio ns.
- Replace th e flat tire w ith a n ew one and
have it ins talled o n your ve hicle as soon as
poss ible to re st ore the hand ling advant ages
of a uni direct io na l t ire .
Notes on wheel changing
Please rea d the information ¢ page 233, New
tires and replacing tires and wheels
if you are
going to use a spare t ire which is different

Afte r you change a tire :
-Check the tire pressure on the spare imme­
diately after installation . What do I do now? 249
- Have the wheel bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
qualified workshop.
- With steel and alloy wheel rims , the wheel
bolts are cor rectly tightened at a torque of
90 ft lbs. (120 Nm ).
- If you notice that the wheel bolts are cor·
roded and difficult to turn while changing
a tire, they should be replaced before you

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repairs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servic ing in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authorized Audi dealer or any properly
equ ipped and qua lified workshop. We st rong­
l y urge you to g ive your authorized Audi dea ler
the opportunity to perform all scheduled
maintenance and necessary repairs . Your dea l­
er has the facilities, original parts and trained
specialists to keep your veh icle running prop­
erly.
Performing limit ed m aintenance you rself
The following pages describe a limited num­
ber of procedures which can be performed on
your vehicle with ordinary too ls, should the
need arise and trained personnel be unavaila­
ble. Before performing any of these proce­
dures, always thoroughly read all of the appli ­
