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 ¢

ue tank is completely empty, the engine will
not start again after the ignition is switched
off.
-Ad Blue is required by law to operate this ve­
hicle .

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
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old or inappro­
pr iate brake fluid . Observe these precau­
t ions:
230
- Use only brake fluid that meets SAE spec i­
ficat io n
J 1703 and conforms to Federal
Motor Vehicle Sta ndard 116 . Always check
with your aut horized Aud i dea ler to make
su re you are using the correct brake fl uid .
The co rrect type of brake f lu id is also ind i­
cated on t he b rake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the b rakes can cause a vapor lock if the
brake fluid is left in t he system too long.
This can se riou sly affec t the efficiency of
the b rakes as well as yo ur sa fety. This
could result in an acc ident .

Bra ke fluid will damage the pai nt of you r vehi­
cle.
@ For the sake of the environment
B ecause of the prob lem of prope r disposal of
b rake fluid as well as the spe cial tools re­
q ui red and the necessary ex pert ise, we rec ­
ommend that you have the brake f lu id

Battery
General information
U nder normal operat ing conditions , the battery
i n you r Aud i does not need any maintenance.
With
high outside tem pera tures or long d aily
drives we recommend that you have the e lectro­
l yte level checked by an a utho rized Audi dea le r or
qualified workshop. The electrolyte leve l should
a lso be checked each time the battery is charged
¢ page 232.
Have the battery checked when yo u take your ve ­
hicle in for service. You a re well advised to re­
place a battery that is older than 5 years.

Wheels
check the wheel alignment if
there is unusual wear.
- Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 inch (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion ¢
fig. 205. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The t ires have reached the mini­
mum tread depth

have worn down to the treadwear
indicators. Replace the tires with
new ones ¢Ai..

recommended to ensure the tires
wear evenly . To rotate wheels, in­
stall the wheels from the rear

axle on the front axle and vice ver­
sa. This will allow the tires to
have approximately the same
length of service life .
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall ¢
page 264.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid­
den. Unusual vibrations in the ve­
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately .
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized repair facility to
have the vehicle inspected.
8_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the
risk aquaplaning when driving
through water, when driving

Wheels
Quality grades can be found where applicable on
the tire side wall between t read sho ulder and
maximum sect ion w idth
c::> page 235, fig . 204.
For example: Tr ead wear 200 , Tract ion AA, Tem­
peratu re
A .
All passenger ca r tires must confo rm to Federal
Safety Req uiremen ts in add it ion to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r controlled conditions on a spec ified gov­
ernment test course.
For examp le, a t ire graded 150 would wear one
and one half ( 1 1/2) t imes as well on the govern­
ment course as a tire graded 100 .
The relat ive performance of t ires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations i n driving hab its, service practices and
d iffe rences in road character istics and clima te.
Traction
The traction grades, from highest to lowest, are
AA, A , Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measu red u n­
de r controlled cond it ions on spec ified govern­
ment test su rfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c::> &_ .
Temperature
The temperature grades are A (the highest), B,
a nd C, rep resent ing t he tire's res istance to the
genera tion of heat and its a bility to dis sipate
heat w hen tested unde r controlled cond itions on
a specified indoo r laboratory test whee l.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and red uce tire life,
a nd excessive tempera ture can lead to sudden
tire failure
c::> &. .
The grade C co rresponds to a level of perform­
ance wh ich a ll passenge r ca r tires m ust meet un­
de r th e Federal Motor Vehicle Safety S tandard
No. 109. G rades Band A represent higher levels
252
of pe rformance on the laboratory test whee l than
the minimum required by law .
A WARNING -
The traction grade assigned to th is tire is
based on straight-ahead braking tract ion
tests, and does not include acce lerat ion, cor­
nering, hyd roplaning or peak traction charac­
teristics.
A WARNING
The temperature g rade for th is tire is estab­
lished for a tire that is properly inf lated and
n ot ove rloaded. Excess ive speed, underi nfla­
tion, o r ex cess ive lo adi ng, eithe r separately or
i n comb inat io n, can ca use heat bu ild up and
possible tire failure.
A WARNING
Tempe ratu re grades apply to ti res that are
properly inflated and not over or underinflat­
ed.
