It is normal for the oil consumption of a new en­
gine to reach its lowest va lue after a certain mile ­
age has been driven.
You must d rive yo ur vehicle about 3,000 miles
(5,000 kilometers) before you can properly as­
sess oi l consumption.
This also applies to fuel consumption and engine
output.
(y Note
- Have you r vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
l et. Lack of proper maintenance as well as
improper use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Contro l System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, wh ich are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.. Try to avoid driving short distances with a cold
engine.
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy cl imbs to 12 mpg (20 l/100
km) . After about
2.5 miles (4 km), the engine is
at its proper operating temperature and fuel
economy has reached a normal level. So you can
see that you should avoid short trips whenever
possib le.
Driving and the environment
The outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.

should cove r the leathe r to protect it from
d irect sunlight.
{D Tips
- Insects are easier to remove from paint that
has been fresh ly waxed.
- Regular waxing can prevent rust spots from
forming.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv ­
ice for a longer time, contact your authorized
A udi dealer or qualified repair facility. They will
advise you of important measures, such as corro­
s ion protection, maintenance and storage proce­
dures. Also follow the information about the bat­
tery~
page 230 .

Fuel and Refu elin g
Many gasoline grades are blended to perform es­
pecially we ll for winter or summer driving . Dur­
ing seasona l change-over, we suggest that you
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
@) Note
-Fuels containing a high percentage of etha­
nol such as ESO and E85 may only be used in
vehicles with flexible fuel* engines. Using
high ethanol fuel in vehicles not equipped
with flexible fuel* engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may cause corros ion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter.
- If you are unable to determine whether or
not a particular fue l blend meets the speci­
ficat ions, as k your service station o r its fuel
supplier.
- Do not use fuel for wh ich the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resu lting from the use of fue ls differ­
ent from those specified are not the respon­
sibility o f Audi and are not covered unde r
the New Vehicle or the Emission Control
System Warranties .
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends we
'
recommend that you switch to unblended
fuel.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flex ible fuel engine
You con recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flop.
Vehicles with flexible fuel engines may be operat­
ed with bio-ethanol fuels such as E85 (85% etha­
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95). The vehicle may also be operat­
ed w ith a m ixture of these fuels.
214
Your fuel consumption wi ll increase when using
bio -ethano l fue ls due to the lower amount of en­
ergy contained per unit volume in ethano l.
Warming up the fle xible fuel engin e in low
t e mperatu res
Due to the chemical composition of bio -ethanol,
a certain amount of fuel ends up in the engine oil
when driving short distances in very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up.
II Please war m up e ngi ne .
If the driver message appears in the instrument
cluster disp lay, drive with a warm engine to re­
duce the oil leve l.
(D Note
-Never fill with methanol or with a h igher
percentage of bio-ethanol than 85% (E85).
A higher percentage of bio-ethanol in the
fuel can cause damage to the engine or to
the fuel system.
- If you use only E85, it is recommended to
fill the fue l tank comp lete ly with unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes­
itat ion driveab ility problems, fill the fuel
tank comp letely with unleaded premium
grade gasoline and drive it normally until
the gaso line is used. See your author ized
Audi dealer if the problem persists .
- Inform your author ized Audi dealer that you
are operating or have operated the vehicle
with E8S.
- Read and follow the information and t ips
about gasoline~
page 213 .
(D Tips
It may take longer to start the engine when
the outs ide temperature is very cold. If poss i­
ble, use winterized fue l if tempe ratures are
below freezi ng.

Gasoline additives
Appl ies to vehicles: with gaso line engine
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline yo u use.
Although gasoline grades differ from one manu­
facture r to another, they have certa in things in
common. A ll gasoline grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake va lves. A l­
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
fuels, built-up carbon deposits can rob your en­
gine of peak performance .
CD Note
-Damage or malf u nction 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 your fuel tank.
Diesel fuel
Applies to veh icles: with d iesel e ng in e
Always use ULSD (Ultra Low Sulfur Diesel) No. 2.
The ULSD No. 2 meets the ASTM O97S.
Diesel fuel with concentrat ions of biodiesel high­
er than S
% such as B11, B2O or B1OO are strictly
prohibited.
Service station fuel pumps are labeled w ith the
correct fuel information for easy recognition by
the user .
If the diesel fuel pump is not labeled
ask the station operator what fuel is being d is­
pensed before filling up your vehicle.
ULSD No. 2 may not be ava ilab le outside the USA
and Canada. Be sure to check before traveling to
other countries .
Fuel and Refueling
ULSD No. 2 can become thicker in very cold tem ­
peratures, and this can impair the engine's start­
ing and running. Depend ing on the season, gas
stations provide ULSD No. 2 that flows better in cold temperatures so that you can cont inue oper­
ating your vehicle as usual.
CD Note
- Your vehicle's diesel engine was designed
soley for use w ith ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severe ly damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
any circumstances. Immediately contact the
nearest authorized Audi dealer or author­
ized Aud i Service Facility for assistance .
These fuels contain substances that can se­
vere ly damage the fuel system and the en­
gine if the engine is started.
Refueling
Fuel filler neck
The fue l filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power lock ing system should fail, you can
still open the flap manually -for detailed instruc­
tions see
¢ page 217.
You can find the fuel tank capacity of your vehicle
in
¢ page 278.
The label on the inside of the fuel f iller flap tells
you the correct fuel for your veh icle. For more in­
formation about fuel specifications, see
¢page 213.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature helps to pre­
ven t fu el vapors from escap ing from the tank and
polluting the environment while yo u refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully .

Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (Ad Blue) is injected into the ex­
haust system before
a nitrogen oxide catalytic
converter to reduce nitrogen emissions .
The AdBlue is carried in a separate tank in the ve­
hicle. The AdB lue usage accounts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used.
When a message about refilling the Ad Blue ap­
pears in the instrument cluster disp lay, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility ¢

Cooling system
Coolant
T he engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
T he cooling system has been filled at the factory
with a permanent coolant which doe s not need to
be changed . T he cool ant consists of a mixture of
specia lly condit io ned water and the ma nufactur ­
e r's g lycol-basedcoo lant additive G 13 antifreeze
w ith a nticorros ion add itives (50% for USA mod­
e ls; 60% for Canadian models) . Thi s m ixt ure bot h
a ssures the ne cessary frost protection and pro­
tec ts meta l components in the engine 's cooling
system from corrosion and sca ling. It a lso raises
the boiling point of the coolant.
D o not red uce the conce ntra tion o f th e coo lant i n
the summer by add ing p la in wa ter.
The propor­
tion of coolant additive must be at least 50% but not more than 60 %
to maintain antifreeze
protection and cooling efficiency . If the coolant
frost protection is too low, the coolan t could
freeze and damage t he vehicle heat ing and en­
g ine cooling system .
For yea r-round driving, antifree ze is added at the
factory for tempe ratu res down to:
- -31°F ( -35°C) USA
- - 4 0°F ( - 40°C) C anada .
I f yo u mu st add coo lant, use a m ixt ure of wate r
a nd coolant add it ive. Mixing the coolant additive
with d istilled water is recommende d.

@ Note
- Be fore winte r sets in , have the coo lant
checke d to see if the coolant additive in you r
vehicle is sufficient to meet the climate con­ diti ons. This is espec ia lly important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the p ropo rtion
o f coolan t addi tive to 60%.
- Whe n adding coolant additive to your cool­
ing system, remember :
- We recommend using o nly coo lan t add i­
tive G12++ o r G13 fo r yo ur vehicle . This
coolant ad dit ive is available at author ized
A ud i dealers . Othe r types of antifreeze ca n
significantly reduce cor rosion protect ion .
The resulting cor rosion can ca use a loss of
coolant a nd serious e ngine damage .
- Do not add any type of rad iator leak sealant
to your vehicle's engine coolant. Adding ra­ diat or repa ir flu id may adverse ly affect the
function and perfo rmance of your cooling
system and cou ld result i n damage not cov­
ere d by your New Vehicle Lim ited W arra nty .

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 223.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on¢
page 18 and ¢ page 28 . Do not
continue to operate the vehicle . The complete
brake system shou ld be thoroughly checked by an
author ized Audi dealer or qualif ied workshop and
the cause corrected. If the brake fluid level is too low, the brake warning/indicator light will illum i­
nate. Contact an authorized Aud i dealer
immedi ­
a tel y.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake flu id abso rbs moisture from the a ir . If the
water content in the brake fluid is too high, cor­ rosion in the b rake system may result after a pe ri­
od of time. The boiling point of the bra ke fluid
will also decrease conside rably and decrease
b ra ki ng per fo rmance .
Therefore, th e brake flu id must be changed
ev ery
tw o years .
Always use new b rake fluid w hich con­
forms to Fede ra l Motor Vehicle Standa rd " FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re, we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer .
Your dealer has the cor rect too ls, the
right brake f luid and the know -how to do t his for
