Fuel and Refueling
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ital engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon depos its can rob your en­
g ine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty .
- Do not add aftermarket fuel additive prod­
ucts to yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel f iller flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
c> page 202.
You can find the fuel tank capacity of your vehicle
in
c> page 256 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in­
formation about fuel specifications, see
<=>page 198.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature he lps to pre­
vent fuel vapors from escaping from the tank and
200
polluting the environment whi le you refuel your
vehicle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fue l can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a col lision.
If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.

Refuelling proc edure
.,. Inse rt the fue l nozzle from the gasoline pump
into the fuel filler neck as far as it will go .
.,. Se lect a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
.,. After filling your tank, tw ist the f uel cap clock-
wise as far as it wi ll go .
.,. Close the fuel filler flap.
To avoid fuel spill ing o r evaporating from the f uel
tank always close fuel cap proper ly and com ­
pletely.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe b urns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injur ies .
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump nozz le fully
into the fuel filler neck could ca use fue l to
spray out of filler neck or to ove rflow. Fuel
spray and overflowing fue l can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause spa rks that can ignite f uel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in except ional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discha rge static ele ctric­
ity befo re touching the filler noz zle ag ain.
Fuel and R efueling
Stat ic elect ricity can cause sparks that can
ignite fue l vapors released during refueling.
- Never smo ke or have an open flame any ­
where in or near your vehicle when ref ueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not trave l with a po rtable fuel
container in your veh icle. The container, fu ll
or empty may leak and co uld cause a fire,
especially in a crash.
- If, under except ional circumstances, you
m ust transport a portable fuel container,
p lease observe the following:
- Never fill a portab le fue l conta iner while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compa rtment, o r on
the trunk). Static electricity can build up
while filling and can ignite fuel vapors caus ing a f ire .
-Always place a portab le fue l conta iner on
the ground before fi lling .
-A lways keep the f iller nozzle comp lete ly
inside the portable container before and
during f il li ng.
- If filling a portable conta iner made of
metal, the filler nozz le must always be in
contact with the container . This will he lp
prevent stat ic elec trici ty from discharging
and ca use a fire.
- Never spill fue l inside the vehicle o r lug­
gage compartment. F uel vapors a re highly
flammable.
- Always observe loca l and state/prov incial
laws rega rding the use, storage a nd trans­
po rtation of fuel contai ners.
- Make ce rtain the f uel con tainer mee ts i n­
dust ry standards (A NSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immed iately to p revent damage
to the pa int.
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,

Fuel and Refueling
the tank is full . Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp ill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling .
- The fuel filler flap of your vehicle is not
l ocked when you lock the veh icle from the
inside .
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and coo l­
ing of in ternal engine components, all internal
combustion eng ines consume a certain amou nt
of oil. Oil co nsumption varies from engine to en­
g ine and may change significant ly over the life of
206
th e engine. Typically, engines w ith a specified
break-in period (see
r=:> poge 185) consume more
o il dur ing the b reak-in per iod than they consume
after oil consumption has stabili zed .
U nder normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscosity of
the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amo unt of o il di lution from water condensa ­
t ion or fuel residue a nd the oxidation level of the
o il. As any engine is subject to wea r as mileage
builds up, the o il cons umption may increase ove r
t i me unt il repla ce m ent of wo rn components m ay
be come necessary .
With a ll these va riab les coming into p lay, no
sta ndard rate of o il cons umption can be estab­
li sh ed or spec ified . T he re is no alte rn ative to reg­
ul ar and frequen t checking of the oi l level, see
Note .
If the yellow engine oi l leve l wa rning symbo l Ill
in the instrument clus ter lights up , you sho uld
c h eck t he o il level as soon as possible
r=:> page 207 . Top off the oi l at your ea rliest con­
venience

A WARNING
Before you check anyth ing in the engine com­
partment, always read and heed all WARN­
INGS
r=:> .&. in Working in the engine compart­
ment on page 203 .
@ Note
Driving wit h an insuffic ient oil level is like ly to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip .
-If you have the impress io n your e ngine con­
sumes excessive amou nts of oil, we recom-
mend th at yo u consult an authori zed A udi .,.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehic le manufac­
turer for a tire of a des ignated
size that has not been driven for more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adj usted.
Curb weight
means the weight of a motor ve­
hicle w ith standard equipment in ­
cluding the maximum capacity of
fuel, oil, and coolant, air condi ­
tioning and additiona l weight of

flation pressures than t he corre­
spond ing standa rd tire. Extra load
tires may be identified as "XL",
"xl" , "EXTRA LOAD" , or "RF" on
the sidewall.
Gross A xle Weight Rating
("GAWR ")
means the load-carrying capacity
of a single axle system , measured
at the ti re-gro und interfaces.
Gross Vehicle Weight Rating
("GVWR")
means the max imum total loaded
weight of the vehicle .
Groove
means the space between two ad­
jacent tread ribs .

Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.

so damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR ") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
230
The Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar

Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.

Winter tires
Win ter tires significantly improve the vehicle's
handling when dr iv ing in winter conditions. Be­
ca use of their const ru ct ion (w idth, compou nd,

.,. Please note that t he maximum permit ted
speed may be lower with winter tires¢.&_ . An
authorized A udi dealer or authorized Audi
Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after insta lling wheels
¢ page 227.
The effectiveness of winter tires is reduced great­
l y when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease g reatly as the tire ages, re­
gard less of the rema ining t read .
_& WARNING
-
-Never d rive fas ter than the max imum pe r­
m itted speed for your tires. This could c ause
the t ires to hea t up too m uch. T his increases
the risk of an accident because it can cause the t ire to burst.
- Always ada pt your driving to the road and
traffic conditions. Drive carefu lly and reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@ For the sake of the environment
Reinsta ll summer tires a t the appropriate
time, beca use they provide better handling
when roads are free o f snow and ice. Summer
tires cause less road no ise, tire wear and fuel

Tire pressure monitoring system
U) General notes
App lies to vehicles: with tire pressure mo nitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicle manufact urer on the vehicle placa rd o r
tire inflat ion press ure label.
(If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
eq uipped with a tire pressu re monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under- inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. Driving on a s ignifi­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Unde r-inflation
a lso reduces fuel e fficiency and tire tread life,
and may a ffec t the vehicle's handling and stop ­
p ing ability .
P lease note that the TPMS is not a substit ute for
p roper tire main tenance, and i t is the drive r's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Wh eel s
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TPMS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfunction, the telltale will flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated. This seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation of replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lfunction te lltale after replacing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lternate tires and
wheels allow the TPMS to continue to function prope rly.
