dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate meas urement of oil cons umption
requires great care and may take some time.
An authorized Audi dealer has instructions
about how to measure oil consumption ac ­
curately.
Checking the engine oil level
Fig. 162 MMI Disp lay: Oil leve l indicator
Read oil level
• Park your vehicle so that it is horizonta lly level.
• Shut the engine off when it is at operating tem-
perature.
• Switch only the ignition back on.
• Wait approx . two minutes.
• Select: Function button
~IC ~A ~R~I > Oil level. Or
• Se lect: Funct ion button
ICARI > Car systems*
control button > Servicing & checks > Oil level.
• Read the oil level in the MMI* Display
r:::>fig. 162. Add engine o il if the bar of the oil
level indicator is near "min"
r:::>page 191
Depending on the way the vehicle is driven and
the operating conditions, oil consumpt ion can be
up to 1 quart per 600 miles (0.8 liter pe r 1,000
km). Consumption may be higher within the f irst
3,000 mi les (5,000 km).
@ Tips
The oil level indicator in the MMI* Display is
only an information disp lay. If the oil level is
too low, a minimum oil warning appears in
the instrument cluster. Add oi l
r::;, page 191.
If the hood has been opened, the current oil
level is shown in the instrument cluster the
next time the ignition is switched on.

specially conditioned water and the manufactur ­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion add itives (50% for USA mod­
els ; 60% for Canadian models) . This mixture both
assures the necessary frost protection and pro­
tects metal components in the engine's cooling
system from corrosion and scaling . It also raises
the boiling point of the coolant .
Do not reduce the concentration of the coolant in
the summer by adding pla in water .
The propor ­
ti on of coolant additive mu st be at least 50 %
but n ot more than 60 °/o
to maintain antifreeze
p rotec tion and cooling efficiency . If the coolan t
frost protection is too low, the coolant cou ld
freeze and damage the vehicle heating and en­
gine cooling system.
F or year-round driving, antifreeze is added at the
factory for temperatures dow n to:
- - 31 °F (-35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you m ust add coolant, use a m ixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
~ A in Working in the engine compart­
ment on page 187.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is suffic ient to meet the climate con­
dit ions . This is especially important if you
l ive in a region where the winter is ex treme-
l y co ld. I f necessary, increase the proport ion
of coo lant add itive to 60%.
- When adding coolant addit ive to your cool ­
ing system, remember:
- We recommend using only coolant addi­
tive Gl2 ++ or Gl3 for your vehicle. This
coola nt add itive is ava ilable at authorized
Audi dea lers. Other types of ant ifreeze can
significant ly reduce corrosion protection .
Check in g and Fillin g
The resulting corrosion can cause a loss o f
coolant and serious engine damage.
- Do not add any type of rad iator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adverse ly affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty .
Checking the engine coolant level and
adding coolant
Be very careful when adding engine coolant.

Checking and Filling
"' Place a thick rag over th e coolant expansion
tank and
carefully turn the cap counter-clock­
wise
¢ ,& .
"'Read the engine coolant level inside the coolan t
expansion tank
¢ fig . 164, ¢page 189,
fig. 16 1.
With a cold engine , the coolant level
should be between the ' 'MIN" and "MAX " mark­
ings
¢ fig . 165 -arrows- . When the engine is
warm, the level may be slightly above the
"MAX" marking.
"'Add coolant mixed in the correct ratio, if neces­
sary ¢
page 192 . Coolant may be a maximum
of 1 mm above the MAX marking.
"' Twist the cap on again
tightly .
The location of the coolant expansion tank can be
seen in the engine compartment illustration
¢ page 189.
To obtain an accurate reading , the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 17 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
Adding coolant
Replacement engine coolant must conform to ex­
act specifications ¢
page 192, Coolant.
We recommend using only coolant additive Gl2+
+ , G l3
or in an emergency Gl2+ . Do not use a
different additive . In an emergency use plain wa­
ter until you can get the correct additive and can
194
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
,&_ WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti ­
freeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
- Coolant pollutes the environment and could
-
cause an engine fire. Excess coolant will be .,.

Checking and F ill in g
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the a ir. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also dec rease conside rably and dec rease
b ra ki ng perfo rman ce.
Therefore, the brake flu id must be changed
e ve ry
two y ear s.
Always use new b rake fluid wh ic h con­
forms to Fede ral Motor Vehicle Standard " FMVSS
1 16 DOT 4".
The brake fluid reservoir 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 re ct too ls , the
righ t brake fluid an d 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 o r inappro­
pr iate bra ke fluid . Observe these p recau­
t ions:
- Use on ly bra ke fluid t hat meets SA E speci­
fication
J 17 03 and confo rms to Fede ral
M otor Vehicle S tand ard 116 . Always check
wit h your author ized Audi dea ler to make
sure yo u are using the correct brake f lui d.
The cor rect type of b rake fluid is a lso indi­
cated on the bra ke fluid reservo ir.
- The brake fluid m ust be new. Heavy use of
the bra kes can cause a va por l ock if the
brake fluid is left in the system too long.
This ca n ser iously affect the effic iency of
the brakes as we ll as your safety . This
co uld res ult in an accident.
@ Note
Brake f lu id will damage the paint of y our vehi­
cle.

® For the sake of the environment
Because of t he prob lem of prope r disposal of
brake fluid as well as the special tools re­
q uired and the necessary expert ise, we rec­
ommend that yo u have the brake f lu id
changed by your autho rized Aud i dea le r.
Battery
General information
Under normal operating conditions, the battery
i n your A ud i does not need any maintenance .
With
high outside temperatures or long dai ly
drives we recommend that you have the e lectro­
l yte level checked by an aut horized Aud i dea ler or
qualified workshop . The e lectrolyte leve l should
also be chec ked each time the batte ry is cha rged
¢ page 198.
Have the battery checked when you take your ve­
hicle i n for service . You are well adv ised to re ­
place a battery that is older than 5 years .
With certain types of airbag deployment, the bat­
tery is disco nnected from the ve hicle elect rical
system for safety reasons
¢ A in Repair , care
and disposal of the airbags on page 141 .
Disconnecting the battery terminals
Some vehicle functions (power window reg ula­
tors, for example) are lost if the battery te rm i­
nals are d isconnected . These funct ions have to be
r elearned after the battery t ermina ls are con­
nected again . To prevent t his, the battery sho uld
o nl y be disconnected from the ve hicle e lectr ica l
system when absolute ly necessary fo r rep airs.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period of
several days or weeks, electrical components are gradua lly cut back or sw itched off . T his reduces
energy cons umption and mainta ins start ing ca­
pabili ty ove r a longer period¢
page 175.
Some of the convenience funct ions may not ope r­
ate, such as the inter ior lights or the power s eat
adjus tment . The conve nien ce f unct io ns w ill be
ava ila ble again when you tu rn on the ig nition an d
star t the eng ine. ..,..
