@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The 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 sea led and generally re­
q uir es lit tle atten tion .
The cooling system has been filled at the fac ­
tory with a pe rmanent coo lant which does not
need to be c hanged. The coolant consists of a
mixture o f spec ial ly conditioned water and the
manuf acturer 's glyco l-based cool ant ad di-
tiv e G13 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els) . This mixture both assures the neces­
sary frost protection and p rotect s metal com ­
ponents in the engine's coo ling system from
corrosion and scaling . It a lso raises the boil­
i ng point of the coolant .
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add it ive must be at
l e a st 50 % but not mor e than 60 %
to main­
tain antifreeze protection and coo ling efficien­
cy .
If the coolant frost protect io n is too low,
the coolant cou ld free ze and dam age the veh i­
cle heating and eng ine cooling system.
For yea r-round driving, antifreeze is added at
the fac to ry for tempera tures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.
Checkin g and fillin g 231
If you must add coo lant, use a mixture of wa ­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended.
_& WARNING
Before you c heck anything in the engine
compartment, always read and heed a ll
WARNINGS
c> .& in Working in the engine
comportment on page 224.
Q) Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate condi tions. This is especi ally impor­
tan t if you live i n a region wher e th e win­
ter is ex treme ly co ld. If necessary, i n­
crease t he p ropo rtion of coo lant add itive
to 60% .
- Whe n ad ding coolant additive t o yo ur
c ooling sys tem, reme mbe r:
- We recommend using on ly coolant ad­
d itive G12++ or G13 (check the labe l)
fo r your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs .
Ot he r ty pes of antifree ze can sign ifi­
cantly reduce corros io n protection. The
r es ult ing co rrosion can ca use a loss of
coolan t and serious e ng ine damage.
- Do not add any ty pe of rad iator leak seal­
a nt to yo ur vehicle 's engine c oolant .

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 237.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

pair, core and disposal of the airbags on
page 163.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, ele ctrical compo­
nen ts are gr adually cut b ack o r swi tched off .

yo u sw itch on the ign ition an d start the en­
gine.
Winter operation
D ur ing the w inte r mon ths, bat tery ca pa city
tends to decrease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used mo re often.
Avoid unnecess ary powe r consumpt ion, pa r­
ticu lar ly in city traffic o r when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in¢
page 23 7. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freez e. This will
p reve nt it from be ing dam aged and having
to be repl aced .
Working on the battery
Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t­
ment under the floor . B efo re you che ck any­
thi ng in the luggage compartment,
read and
heed all WARNINGS

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressures for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase the
fuel consumption.
Tires and vehicle load limits
There are limits to the amount of load or weight that any veh icle and any t ire ca n carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in­
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi­
t ion has a safety belt
Q page 138, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balan cing, correct tire pressure and driv­
ing style.

the tire sidewall (for example "TWI" or other
symbols) ind icate the positions of the tread
wear indica to rs. Wor n tires must be replaced .
Different figures may apply in other countr ies
¢ .&_ .
Tire pressure
Incorrect t ire pressure causes premature wea r
and can cause sudde n tire blow-out . For this
reason, tire pressu re must be checked at least
o nce a month
¢ page 246 .
Driving style
Driving fast around c urves , heavy accelerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
F or all four tires on your ve hicle to have the
same service life, we recomme nd that the
front and rear tires are rotated accord ing to
the tire manufact urer's suggested tire rota­
tion intervals. Please remembe r th e follow­
i ng:
- T ire rotation intervals may differ from the
veh icle service intervals o utli ned in your
Warranty
& M ain tena nce booklet.
- The longer one tire is used in one location
on t he vehicle, the more it wears at certain
points; the refore , we recommend that you
follow the tire man ufac turer's suggested
tir e rotat ion intervals.
- Ve hicles w ith front -wheel dr ive experience
more trea d wear on the fro nt wheels com­
pa red to all-wheel d rive (q uattro).
- Please rotate tires as shown ¢
fig. 198 .
-Extra care must be taken when rotating di-
rection -spec ific tires ¢

268 What do I do no w?
P uttin g on the spare wheel
.. Lift the spare wheel and ca refully slide it
over the alignment pin to guide it in place
¢ (D .
.. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bolts
slightly.
.. Remove the alignment pin and insert and
t ighten the remaining wheel bolt slightly
l ike the rest .
.. Turn the jack handle counte r-clockw ise to
lower the vehicle unt il the jac k is fully re­
leased.
.. Use the wheel bolt wrench to tighten all
wheel bolts firmly¢
page 265 . Tighten
them
crosswise, from one bolt to the (ap­
proximately) opposite one, to keep the
wheel centered.
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you .
(j) Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or t ighten
the wheel bolts .
- Pull the reversible blade from the screw­
driver before you use the hexagonal
socket in the handle to turn the wheel bo lts.
- When mounting tires with
unid ir ec tional
tread design
make su re the tread pat­
tern is pointed the right way
¢ page 268.
-The wheel bolts should be clean and easy
to tu rn . Check for d irt and corrosion on
t h e mat ing s urfaces of both the whee l
and the h ub. Remove al l dirt from these
s ur faces before remo unting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire w ith a tre ad pattern
intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection , please
note the following :
- The direct ion of rotation is marked by an ar­
row on the side of the ti re .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optim um performance cha racte r­
is tic s wit h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu la r at­
t en tion to th is fact d uring wet wea ther and
t ha t you adjust you r speed to match road
conditions .
- Replace the fl at tir e with a new o ne an d
have it insta lled on you r vehicle as soon as
possible to resto re the handling advantages
of a u nidirectional tire .
Notes on wheel changing
Please read the information¢ page 251, New
tires and replacing tires and wheels
if you a re
going to use a spare tire which is different
from the ti res on your vehicle .
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after install ation.
- Have th e whe el bolt tightening torque
c hecked with a torque wrench as soon a s
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel rims, the wheel
bolt s are cor re ctl y tightened at a torque of
90 ft lb (120 Nm ).
- If you noti ce that the wheel bolts are cor­
roded and diffi cult to turn while changing
a ti re , they should be replaced before you
check the t ightening torque. .,..
