2011 AUDI TT ROADSTER gas type

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 175
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see ¢
page 177.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 239.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see ¢
page 174.
Your vehicle fue l tank has an on -board refue l­
li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara ­
tive ly small patch of rubber on each tire that
assures that a ll-important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your veh icle and its t ires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from roa d haza rds and
r eg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid s udden tire failure in­
cluding tread separat ion and blowouts.
Avoiding damage
If you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls incl ud ing gre ase, o il,
gasoline and b rake fluid off the t ires .
Inspect the t ir e s regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires
Mark ti res when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims.
New tires
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You must
f ol low the specified d irec tion of rot ation . This
is necessa ry so tha t these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.

A WARNING
-New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 3 50 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fla tion, crashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- Ti res age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

204 Tires and wheels
c::>fig . 148 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (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 tire blow-out . For this
reason, tire pressure must be checked at least
once a month
c::> page 200.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For a ll 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 interva ls may differ from the
vehicle serv ice intervals 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 manufacture r's suggested
t ir e rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com ­
pared to all-wheel drive (quatt ro ® ).
- Please rotate t ires as shown
c::> fig . 149.
-Extra care must be taken when rotating di-
rect ion-specific tires
c::> page 226.
Wheel balancing
The whee ls on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steering wheel. Unbalanced
wheels must be rebalanced to
avoid excessive wear on steering, suspension
and t ires . A whee l must also be reba lanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type .

A WARNING
-Sudden tire fai lure can lead to loss of con-
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your r isk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.
