gas type AUDI A5 COUPE 2011 Owners Manual

Fuel supply and filling your fuel tank
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice station or its fuel
supplier.
• 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 responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance problems 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 manufacturers 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance.
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fuel filler flap .
If the power locking system should fail, you can still open the flap
manually- for detailed instructions see~
page 273.
You can find the fue l tank capacity of your vehicle in Technical Data
~page 339.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 269.
Your vehicle fuel tank has an on-board refue lling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least appreciated and most abused pa rts of a motor
vehicle . Tires are, however, one of the most important parts of a
vehicle , pa rticul arly conside ring the comparat ive ly small patch of
rubber on eac h tire that assures that all-important contact between
you, your veh icle and the road.
Maintai ning t he cor rect tire pressu re, mak ing su re that your veh icle
and i ts tires do not have to carry more weight t han they can safely
hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid
o ff t he t ires .
Ins pect the ti res regularly for damage (cu ts, cracks o r blisters, e tc.) .
Remove any foreign bodies embe dded in the treads.
Storing tires
M ark tires w hen yo u remove t hem to indica te t he d ire ct io n of rota ­
tion . This ensures you to be ab le to mount them correctly when you
re insta ll them.
Whe n removed, t he wheels or tires should be sto red in a cool, dry and
preferably da rk p lace.
Safety first
Store tires in a v ertica l pos it io n if they a re not mount ed on rims, in a
hor izonta l posit ion if they are mounted on r ims.
New tires
N ew tires have to be broken in~ & .
Th e tre ad d epth of new ti res may v ary, accor ding t o th e type an d
make of t ire and the tread pattern .
Hidden damage
Damage to tires and rims is often not readi ly visible. If yo u notice
unu sual vib ra ti on o r the ve hicle pulls to one side, t his may in dica te
that one of the t ires has been damaged. The tires must be checked
im media tely by an auth oriz ed A ud i d eale r or qual ifie d wor ks hop.
Unidirectional tires
A un id irectional tire can be identified by arrows o n th e sidewall , th at
point in the direct ion the t ire is designed to rotate. You must fo llow
t he s peci fied dire ction o f ro tat io n . This is neces sary so t hat t hese
tires can deve lop their optimum cha racte ristics regard ing g rip, road
noise, we ar an d hy dropl aning res ist an ce. F o r more informat ion

& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must also be broken-in . To
reduce the risk of losing control, a collision and serious personal
injuries , drive with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately. _..

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss 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 with special care and at
lower speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
