234 Check ing and filling
@ 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 little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer 's glyco l-b ased coo lant add i-
tive G l3 antifreeze with ant icorrosion addi
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es
sary frost protection and protects metal com ponents in the engine's cooling sys tem from
corrosion and scaling . It a lso raises the boil
ing point of the coolant .
Do not red uce the concentration o f the coo l
ant in the summer by adding plain water.
The
proportion of coolant add itive mu st be at
l e a st 50 % but not more than 60 %
to main
tain antifreez e protection and cooling efficien
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld freeze and damage the veh i
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 22
7 .
(D 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 conditions . This is especia lly impor
tan t if you live in a reg io n where the win
t er is ex treme ly cold. If ne cessa ry, i n
crease the pr opo rtion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c oolin g sys tem, remembe r:
- We recommend using on ly coolant ad
d itive Gl2++ or Gl3 (check the label)
for your vehicle . This coolant additive is
ava ila ble at autho rized Aud i deale rs.
Other types of antifreeze ca n sig nifi
ca ntly reduce co rr os io n protection. The
r es ult ing co rrosion c an c ause a los s o f
coolant and serious engine damage.
- Do not add any type of rad iator leak seal
a n t to y our vehicle 's engine coolant.

Changing brake fluid
Have the brake fluid changed by an experi
enced technician .
Brake fluid absorbs mois ture from the air. If
the wa ter content in the brake fluid is too
high , corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
ev ery two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4 ".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author
i zed
Audi dealer . Your dealer has t he correct
tools, the right brake fl uid and the know-how
to do this for you.
A WARNING
-
- Brake fluid is poisonous . It must be stor
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap
propriate brake f luid. Observe these pre
cautions:
- Use only brake fluid that meets SAE
spec ificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong . This can seriously affect the effi
c iency of the brakes as well as your
safety. Th is cou ld resu lt in an accident .
(D Note
Brake fluid will damage the paint of your

age the wheelhouse and other parts of
the veh icle.
(D} Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed r ims. If different rims
are fit
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
¢page 287.
_& WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel bol ts an d the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be prop
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the correct tighten ing
torq ue for the wheel bo lts to reduce the risk of a whee
l loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tighte ning torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
([) Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago
nally. Afte r changing a whee l, the torque
must be checked as soon as possible wi th a
torque wrench -pre ferably by an au thor
ized Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling u nder a var iety of d riv ing condi
t ions . As k your author ized Audi dealer for
more details.
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral rep resents the ratio
of the t ire's s idewa ll height in relation to its
t read width ex pressed in percentage. Conven
t iona l tires have a he igh t/w idth rat io of 60 or
more.
The performanc e of low -a sp ec t-ratio tires i s
pa rticularly sensitive to improper inflation
pre ssure . It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always befo re a long trip
