2011 AUDI A3 air condition

___ C_ h_ e_c _k _i _ n _g ~ a_n _d_ f_il _l_in _ g _________________________________________ _
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and-go traff ic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been run ning for a short time . This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oi l standard VW 502 00
(vehicles with gasoline engine) or VW 507 00 (vehicles with diesel
engine). Your Limited New Vehicle Warranty does not cover damage
or malfunctions due to failure to follow recommended maintenance
and use requirements as set forth in the Audi Owner's Manua l and
Warranty
& Maintenance booklet. Your dealer will have to deny
warranty coverage unless you present to the dealer proof in the form
of Service or Repair Orders that all scheduled maintenance was
performed in a timely manner .•
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumpt ion varies from engine to engine
and may change significant ly over the life of the eng ine. Typically,
engines with a specified break- in period (see~
page 197) consume
more oi l during the break-in period than they cons ume after oil
consumption has stabilized.
Under normal cond itions, the rate of oil consumpt ion depends on the
quality and vis cosity of the oil, the RPM (revol utions pe r minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oi l dilution from water condensation or fuel residue and the ox
idation level of the o il. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil level warning symbol in the instrument
cl uster .... lights up, you should check the oil level as soon as possible
with the oil dipstick~ page 231. Top off the o il at your earliest
convenience ~
page 232.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 226.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't::r. is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and alway s
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amounts of oi l, we recommend that you consu lt your authorized Audi
dea ler to have the cause of your concern properly diagnosed. Keep in
mind that the accurate measurement of oil consumption requires
great care and may take some time . Your authorized Audi dea le r has
instructions about how to measure oil consumption accurately. •

Checking and filling --------------------=------=:;______,.J VPII
You can mix the G12++ coolant additive with other additives G12+ or
Gl2. Always check with yo ur authorized Aud i dealer.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS =>
& in "W orking in the engine
co mpartment " on
page 226.
0 Note
• Before winter sets in, have the coolan t checked to see if the
coolant additive in your vehicle is sufficient to meet the clima te
conditions. This is especially important if you live in a region where
the winter is extremely cold . If necessary, increase the proportion of
coo lant additive to 60%.
• When adding coolant additive to your cooling system, remember :
- We recommend using only coolant additive
G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Vehicle OP-eration
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.

Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working in
the engine compartment" on
page 226.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank=> fig. 166 . With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max" marking .
The location of the coolant expans ion tank can be seen in the engine
compartment illustration=>
page 227.
To obtain an accurate reading, the engine must be sw itched off.
The expans ion tank in your vehicle is equipped with an electric coolant
level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System =>
page 32 will blink until you add coolant and the level has
been restored to normal. Even though there is an elect ric coolant

vehicle at its maximum capacity weight and tires that were on your
vehicle at the tim e it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants) , you can adjust tire pressures to
those specified for normal vehicle load. Before operating the
vehicle at maximum load, you must increase the tire pressures to
those specified for maximum vehicle load
=> &.
Bear in mind that the tire pressure monitoring system* ca n only
monitor the tire pressures you have stored. The system does not
recogn ize the load condit ion of your vehicle.
The effectiveness of the tire pressure monitoring system* wi ll be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load

The tires and rims are essential parts of the vehicle's design. The tires
and r ims approved by Audi are spec ially matched to the characteris­
tics of the vehicle and can make a major contribution to good road
holding and safe handling when in good condition and properly
inflated =>& .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer. They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilit ies for disposing of the old tires.
Authorized Audi dea lers have the necessary information about tech­
nical requirements for installing or chang in g ti res and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not ind ividually (for
example both front tires or both rear t ires together).
Be sure to read and heed the tir e pressure monitoring system*
information=>
page 264.
Always buy replacement radial tires that have the same specifications
as the tires approved for your veh icle by Audi . Replacement tires must
always have the same load rating specification as the original equip­
ment or approved opt iona l tires listed in the table=>
page 249.
Audi-approved spec ification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road­
holding, driv ing characteristics, and safety of the vehicle. The table (=>
page
249) lists specifications of the tires approved for the Aud i
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-p illar or inside
the fuel filler flap(=>
page 249, fig. 172) lists the specifications of
the original equipment tires installed on your ve hicle at the time it
was manufactured.
Federal law requires tire manufact urers to place standardized infor­
mation on the sidewall of all tires =>
page 2 5 7, fig. 17 5. This i nfor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a t ire identification number
for safety standard certification and in case of a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it easie r to choose the correct
tires. Rad ial tires have the tire specifications marked on the s idewall,
for examp le:
P225 / 45 R 17 91H XL
This contains the following informat ion:
P I ndicates the tire is for passenger cars (where applicable)
225 Nominal tire width in mm of the tire from s idewall edge to side-
wa ll edge. In gene ral, the large r the number, the wider the tire
45 Height/width ratio in pe rcent (aspect ratio)
R Tire construction: Radial
17 Rim diameter code (in inches)
91 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD" or "RF") indicates that the tire is "Rein­
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the t ire has some mud and snow capa­
bili ty
The tires could a lso have the information of direction of rotation
=>page 245.

Tread wear
The tread wear grade is a compa ra tive ra ting based on the wear rate
of the tire when tested unde r co ntrolled conditions on a specified
government test co urse.
For examp le, a tire g rade d 150 would wea r o ne and one half (1 1/2)
times as well on the government course as a tire graded 100.
Th e relat ive performance o f tires depends upon t he ac tual con ditions
o f their use, however , and may de pa rt s ig ni ficantly from the norm
due to variations in driv ing ha bits, service prac tices an d differences in
roa d characterist ics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C. Those
grades represent the tire's ab ility to s to p on wet pavemen t as
meas ured under controlled condit ions o n spec ified governme nt test
s u rfaces of asphalt and conc rete. A tire mar ked C may have poo r trac­
ti on perfo rma nce => & .
Temperature
The temperature grades are A (t he h ighest), B, a nd C, rep resenting
the t ire's resistance to the gene rat ion of heat and its ab ility to dissi­
pate hea t when test ed unde r co ntro lled condi tions o n a spe cifi ed
indoor laboratory test wheel.
S ust ain ed high te m peratu re can cause t he mate rial of the tire to
degenerate and reduce tire life, and excessive temperatu re ca n lead
t o sudden tire fail ur e=> & .
Th e g rade C cor responds to a leve l of performance which all
passenger car tires m ust meet under the Fede ral Motor Vehicle
Safety Standa rd No. 109. G rades Band A rep resent higher levels of
per formance on the labo ratory test whee l than the minimum
req uired by law .
Safety first
& WARNING
The traction grade assigned to this tire is based on straight -ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or e xcessive loading, either separately or in combination, can
c ause heat buildup and po ssible tire failure .•
Winter tires
W inter tires can improve vehicl e handling on snow and
ic e. A t temper atures belo w 45 °F (7 °C) we recommen d
ch angin g to win ter tires .
In some heavy snow areas , loca l gover nments may requ ire true
wi nte r o r "snow" t ires, those with very deep ly c ut trea d. These tires
should only be use d in pairs and be i nstalled on all fo ur w heels . Mak e
sure you purchase snow tires that are the same size a nd constr uction
t ype as the ot her tir es o n your ve hicle.
If your veh icle is eq uipped with all-wheel drive*, th is will improve
t raction during w inte r drivin g, eve n with t he standard tires . However,
we st rongly recomme nd that you a lways equi p all four w hee ls on your
vehicle with correctly fitte d winter t ires or a ll-season ti res, w hen
wi nter road conditions a re expe cte d. Thi s also improves the vehicle 's
bra king pe rformance and re duces stop ping distances.
S u mme r tir es pro vide less g rip on ice and snow .
Winter tires (snow tires) must always be fi tted on all fo ur whee ls .
Ask yo ur autho rized Audi deale r or qu alified wor kshop for permitted
winter tire sizes . Use only ra dial w inte r tir es. ..

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Aud i dealer for
more details .
Th e low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation . The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 252, "Checking t ire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact w ith
potholes, curbs, gullies or ridges on the road, particularly if the tire is
unde rinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle , we recomme nd that you observe the following precau ­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive ca refully on roads with potholes, deep gullies or ridges. The
impact from driving through or over such obstacles can damage your
tires. Impact with a curb may also cause damage to your tires .
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible. •
Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflat ion, which could eventually cause tire fa ilure . If
you believe that a tire may have been damaged, replace the tire as
soon as poss ible .
• Th ese tires may wear more quickly than others.
• Please a lso remember that, while these tires deliver responsive
hand ling, they may rid e less comfortably and make more noise than
other choices .
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance t ires originally installed on your vehicle are
intended for maximum dry and wet road perfo rmance and handling.
They are not su itable for cold, snowy or icy weather conditions . If you
drive under those circumstances, you should equip yo ur vehicle with
all-season or w inter tires, which offer better traction under those
conditions . We suggest yo u use the recommended snow or all-season
tires specified for your veh icle, or their equivalent .
Refer to =>

General notes 1
Each tire, including the spare (if prov ided) , shou ld be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or t ire
inf lation pressure label. (If your vehicle has tires of a different size
than the siz e indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper t ire inflation pressure for
those tires.)

& WARNING
• If the tire pressure indicator appears in the instrument cluster
display, one or more of your tires is significantly under-inflated. Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire pressure label=>
page 249.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is responsible for maintaining the correct tire pres­
sures . You must check the tire pressures regularly .
• Under certain conditions (such as a sporty driving style, winter
conditions or unpaved roads), the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle. Your vehicle registration becomes invalid if you use
these tires when not permitted. Damage to your vehicle or acci­ dents could also result.
