maintenance AUDI TT ROADSTER 2015 User Guide

@ For the sake of the environment
Because of the problem of proper disposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Your vehicle is equipped with a special bat­
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re­
p laced w ith an original equipment battery .
Under normal operati ng conditions, the bat­
tery is
maint enan ce -fre e.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than
5 years.
Di sconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are d isconnected. These functions have
to be re learned after the battery terminals are
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lectr ica l system when absolutely necessary
for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo ­
nents are gradually cut back o r switched off .
This reduces energy consumption and main­
tains sta rting capab ility over a longer per iod
c::> page 146. Some of the convenience func­
tions may not operate, s uch as the interior
lights or power seat adjustment. The conven ­
ience functions will be avai lab le again when
you switch on the ignition and start the en­ g ine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as temperatures d rop. This
is because more powe r is also consumed while
Checkin g and fillin g 175
starting, and the headlights, rear window de ­
fogger, etc ., are used more often .
Avoid unnecess ary powe r consumpt io n, p ar­
t icu lar ly in city traffic o r when traveling only
sho rt distances. Let your authorized A udi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::> page 178. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer .
Replacing battery
The new battery must ha ve the same capaci ­
ty, voltage (12 volts), amperage, construction
and plug sea ling, as the original battery. Spec­
ifications are listed o n the battery housing.
Batter ies spec ia lly developed by Audi fulfill
the maintenance, outp ut, and safety require­
ments.
When installing the battery, make sure the ig­ nition and a ll electrical consumers are switch ­
ed off
c::> (D .
We recommend that you use maintenance­
free or
cycle -res istant /leak-proof batter ies
accord ing to the standards TL 825 06 (from
Apr il 2008) and VW 7 50 73 (from Ap ril
2010).
Rep lacing the battery should be carried by a
qualified workshop. Please fo llow the instruc ­
tions on the battery cover.

190 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

f ~----~
~ ..__ ____ __,
Fig. 139 Rotating t ires for more ev en wea r
Tread Wear Indicator (TWI)
The origina l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 138 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn tires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 186.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro) .
- Please rotate tires as shown
c::> fig. 139.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 211 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
all-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type .

Maintenance
' General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
safety, economy and reliability . For detailed
vehicle maintenance consult your Warranty
&
Maintenance booklet.
Under difficult operating conditions , for ex­
ample at extremely low outside temperatures ,
in very dusty regions, etc., some service work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air fi lter.
@ For the sake of the environment
By regu larly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus min imizing adverse
effects on the environment.
Important considerations for you and
your vehicle
T he increasing use of electron ics, soph isticat­
ed fuel injection and emission control sys­
tems, and the generally increasing technica l
complexity of today's automobiles, have ..,_

steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also , 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.

_& WARNING
- Serious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs.
- Always be extremely careful when work­
ing on the vehicle. Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r is k personal
inju ry.
- Do not attempt any of the maintenance,
checks or repairs descr ibed on the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re ­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your authorized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the radiator fan. It is temperature controlled and can sw itch on suddenly -
even when the engine is off and the igni­
tion key has been removed. The rad iator
fan switches on automa tical ly when the
coo lant reaches a certain temperature
and will continue to run until the coo lant
temperature drops .
- Always remove the ign ition key before
anyone gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle. The jack supplied with
the vehicle is not adequate for this pur­
pose and cou ld collapse causing serious
personal injury.
- If you must work underneath the vehicle
with the wheels on the ground, always
make sure the vehicle is on leve l ground,
that the wheels a re a lways secure ly
b locked and that the engine cannot be
started.
