238 Check ing and filling
Never mix oil additives with your engine
oil. These additives can damage your en
gine and adversely affect your Audi Limit
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst 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 so il, 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 ui res little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion addi
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil
i ng po int of the coo lant .
Do not red uce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficie n
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35° C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .

(J;) Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in
yo ur vehicle is sufficient to meet the cli
mate condi tions . This is especia lly impor
tant if you live in a region where the win
ter is extreme ly co ld . If necessary, in
crease the p roportion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
cooling system, remember :
- W e r ecommend using o nly coola nt ad
d itive G l2++ or Gl3 for your veh icle.
T his coolan t additive is av ail ab le a t au
thor ized Audi dealers. O ther types of
antifreeze can significant ly reduce cor
rosion protection . The resulti ng cor ro
sion can cause a loss o f coolant and se
rious engine damage.
- Do not add any type of rad iator leak seal

Changing brake fluid
Have the brake fluid changed by on experi
enced technician .
Brake fluid absorbs moisture from the air. If
the water 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
every 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 d ealer. 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
spe cificat 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 f luid 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
vehicle .
248 Tire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so and check the wheels and tires for dam
age.

are designed for the cond itions that are
Glossary of tire and loading terminology
Acces sory weight
means the comb ined we ight (in excess of
those standard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in
dicate a low sidewall for improved steering re
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typica
l in those seasons. Audi recommends
using winter tires during the winter
months. Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very cold tem peratures, cracks ca n form on the tread
bars, resulting in permanent tire damage
that can cause loud driving no ise and un
balanced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pre ssure
means the t ire p ressure recommended by the
vehicle manufacturer fo r a tire of a des ignated
s ize that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi
tioning and additional weight of optiona l
equipment.
Extra load tire
means a t ire design to operate at higher loads
and at h igher inflation pressures than the cor
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -carry ing capacity of a s ingle
axle system , measured at the tire-ground in
terfaces.
Gr oss Vehicle Weight Rating ("GVWR ")
means the maximum total loaded we ight of

258 Tires and wheels
Incorrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impairing the safety of the vehi
cle . If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see Qpage 202 .
.&_ WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of"hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you a re not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .
