Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The ser vice interva l disp lay in the instrument
cluster of your vehicle will inform you when it is
time for an oil change . We recommend that you
have your
oil changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table.

asoline VW S02 00 or
engin e vw S0400
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled
with a high-quality oil
which
can usually be used throughout the entire
year.
CD Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
-
Use only a high quality engine oil that ex-
pressly complies
with the Audi oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
-
Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
Tips
If you need to add oil and there is none availa­
ble
that meets the Audi oil quality standard
your engi
ne requires, you may add a tota l of
no more than O.S qt/l of a high-quality "syn­
thetic" oil that meets the following spec ifica­
tions.
Checking and F illing
-ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE SW-30 or SAE SW-40.
-For more information about engine oil that
has been approved for your vehicle, please

Engine oil consumption
The engine in your vehicle depends on an ade­
quate
amount of oil to lubricate and cool all of
its moving parts.
In order to provide effective lubrication and cool­
i ng
of internal engine components, all internal
combustion engines consume a certa in amount
of oil. Oil consumption varies from engine to en­
gine and may change significantly over
the life of
the engine. Typically, engines with a specified
break-in period
(see~ page 56) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal cond it ions, the rate of oil con­
s u
mption depends on th e qu ality and viscos ity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­
perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds
up, the oil consumption may increase over
t ime
until replacement of worn components may
become necessary.
With all these variab les coming into play, no
standard rate
of oil consumption can be estab­
lished
or specified. There is no alternative to reg­
ular and frequent checking of the oil level, see
Note .
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check
the oil level as soon as possible
~page 240. Top off the oil at your earliest con-
venience

Checking the engine coolant level
""Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q page 238, fig. 184. The coolant level
must be between the markings when the en­
gine
in cold. When the engine is warm it can be
slightly above
the upper marking.
Adding coolant
Requirement: there must be a res idual amount of
coo l
ant in the expans io n tank c:?(i) .
""Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew
the cap counterclockwise
c:?,8..
""Add coolant mixed in the correct ratio
i:?page 242 up to the upper marking.
""Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au­
thorized
Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi­
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch
on even if
the ignition is switched off, which
increases
the risk of personal injury.
CD Note
Do not add coolant if the expans ion tank is
empty . Air could enter the cooling system and
damage
the eng ine. If this is the case, do not
continu e driving. See an authorized
Audi dea l­
er or authorized
Audi Service Facility for assis­
tance.
Radiator fan
The radiator fan switches on automatically by it­
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en­
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.

-The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.
Brake fluid
Checking brake fluid level
Fig. 188 Engine compartment: cover on the brake fluid
reservoir
Before you check anything in the engine compart­
ment, always read and heed all WARNINGS
¢page 236.
~ Read the brake fluid level from the brake fluid
reservo ir ¢ fig. 188, ¢page 238, fig. 184. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location
of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page238.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the brake fluid level falls considerably below
the "MIN" mark, the brake warning/indicator
light .. (U.S. models) I. (Canadian models)
will come on ¢ page 11. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. Ifthe brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer immedi­
ately.
244
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in
the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will
also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed every
two years. Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your authorized Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
8._ WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
-Brake failure can result from old or inappro­
priate brake fluid. Observe these precau­
tions:
-Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with
your authorized Audi dealer to make
sure you are using the correct brake fluid.
The
correct type of brake f lui d is also ind i­
cated 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 long.
This
can seriously affect the efficiency of
the brakes as well as your safety. This
could
result in an accident.
CD Note
Brake flu id will damage the paint of your veh i-
cle .

Downloaded from www.Manualslib.com manuals search engine ~ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired
and the ne cessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information
The battery in your Audi does not need any main­
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem­
peratures or when driving all day. The electrolyte
level should also be checked each time the bat­
tery is charged ~page 247.
Have the battery checked when you bring your ve­
hicle
in for an inspection . It is a good idea to re­
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect­
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l­
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa­
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other­
wise explosive
gas will escape from the bat­
tery and increase the risk of an exp losion. ___ ....J
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
in the luggage compartment, read and heed all

Do not expose the battery to an open flame,
electric sparks or an open light.
-
Do not smoke.
-Do not interchange the positive and nega-
tive
cables.
-When working on the battery, be sure not to
short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could
lead to damage or explosion and personal
injury.
-
When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury .
- Always keep
the battery well out of the
reach of children.
- Before work is
done on the electrical sys­
tem, disconnect the negative ground cable.
- Before
performing any work on the electri­
cal
system, switch off the engi ne and igni­
t i
on as well as any electrical equipment. The
246
-
negative cabl e on the battery m ust be dis­
connected. If you are just going to replace a
light bulb,
then it is enough to switch off
the lights.
- Before di
sconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
w ill
set off the alarm.
-
When disconnecting the battery, first dis­
connect the negative cabl e and then the
positive cable.
- Before
reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect
the positive cable first and then
the negative cable. Never interchange the
cables -this could start a fire!
- Never
charge a frozen or a thawed-out bat­
tery. It cou ld explode! If a battery has fro ­
zen,
then i t must be replaced. A discharged
b attery can freeze ove r at 32 °F (O °C).
-Make sure the vent hose is always attached
to the opening on the side of the battery .
- Never
use batteries which are damaged.
There is th e danger of an exp losion! Always
replace a da maged battery .

Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle Q page 92. The intelli­
gent energy management system will keep the
engine battery charged better than vehicles with­
out this system. To make sure the additional
electrical energy is available once again after you
have
changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those insta lled at the
time your vehicle was delivered). Specificat ions
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
placing the battery.
The new
battery must have the same capacity,
voltage (12-volts) , amperage, construction and
plug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are switched
off.
CD Note
Make
sure the ventilation hose on the side of
the battery is connected, otherwise fumes or
battery acid can leak out.
@ For the sake of the environment
Because
of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all
environmental regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed
immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can

as little exposure to light as
possible.
CD Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
250
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion
protection for this and
could be permanently dam­
aged by road salt or similar
substances.
