ECU AUDI TT 2013 Owner´s Manual

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat 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 -even if it
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 202, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

Tire repair
General and safety pointers
Applies to vehicles: wit h Tire Mobility Sys tem
Tire repair is intended only for temporary,
short-term use .
Fig. 153 Tire damage for whic h the Tir e Mob ility Sys­
tem is not suited
Your vehicle is equipped with a tire repa ir kit,
the
Tire Mobility System (TMS).
In the event of a tire failure, the TMS is in the
luggage compartment under the floor.
It con­
s ists of the tire sealant and an electric air
pump .
Using
TMS , tir e damage caused by foreign
bodies up to about
0.16 inch (4 mm) in diam­
eter can be sealed reliably.
The foreign object can stay in the tire .

(D Note
When removing or installing the wheel,
the rim could hit the bra ke rotor and dam­
age the rotor . Wor k carefully and have a
second person help you.
N ever use the hexa gonal s ocket in the ha n­
d le of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversib le blade from the screw­
drive r before yo u use the hexagonal
socket in t he handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional

- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 227
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover .
Until then , drive with extra care and at re­
duced speeds.

24 4 Con sum er Inf ormation
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Als o, sa fe ty a nd en vir onm ent al con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans­
miss ion parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­
cle and its many systems.
Improper maintenance, adjustments and re­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore, proof of servic ing in accord­
ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop.
We strong ly urge you to give yo ur autho rized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs.
Your dea ler has the facilities, original parts
and trained specialists to keep your vehicle
running properly.
