Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.
@) Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .
- V ehicles wi th gasoline engine: AC EA A3 o r
API SM with a viscosity grade of SAE 0W- 30,
SAE SW -30 or SAE SW-40 .

www .aud iusa.com or www .aud icanada .ca .
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 n g of in ternal engine components, all interna l
combustion engines consume a certai n amount
of oil. O il consumption var ies from engine to en­
g ine and may change significant ly ove r the life of
190
the engine. Typically, eng ines with a specif ied
break-in period (see
¢ page 177) consume mo re
o il dur ing the b reak -in per iod than they consume
after oil consumption has stabili zed.
U nder normal cond itions , the rate of oi l con ­
s u mption depends on t he qu ality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem ­
perature and road condit ions. Further factors are
the amount of o il di lution from water condensa ­
tion or fuel residue and the ox idat ion level of the
o il. As any engine is s ubject to wear as mileage
builds up, t he oil consump tion may inc rease ove r
t ime unt il rep lacement of wo rn component s may
become necessary.
With a ll these va riab les coming into p lay, no
sta ndard ra te of oil consumpt ion can be estab­
li shed or spe cified . There i s no altern ative to reg­
u la r and freq uent checking o f the oil leve l, see
Note .
If the yellow e ngine oi l leve l wa rning symbo l El
in the instr ument cluster lights up, yo u should
chec k the o il level as soon as possible
¢ page 191 . Top off the oil at your ear liest con ­
venience ¢page 191.
A WARNING
Before you chec k anything in the eng ine com­
partment, always read and heed a ll WARN­
INGS¢ .&. in Working in the engine compart­
ment on page 187 .
@ Note
Driving with an insufficient oi l level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going on a long trip.
- If you have the impression yo ur engine con­
sumes excessive amounts of oil, we r ecom-
mend that yo u consult an au tho rized Audi .,.

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

Checking and F ill in g
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow lega l regu lations when
disposing of empty oil containers .
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compa rt ­
ment,
alway s read and heed all WARNINGS ¢ .&.
in Working in the engine comportment on
page 187.
The engine oil must be changed according to the
i n terva ls specified in yo ur Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of o il diminish gradua lly
during normal vehicle use.
Under some circ umstances the engine oi l sho uld
be changed more frequent ly . Change oil more of­
ten if you drive most ly short distances, operate
the vehicle in dusty areas or under predom inantly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures rema in below freezi ng
for extended periods.
Detergent addit ives in the o il w ill make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we stro ngly recommend that you have
your oil changed by an autho rized
Aud i deale r or
a qualif ied se rvice stat ion.
If you choose to change your o il yourself, please
note the fo llowing important information :
A WARNING
To reduce the ris k of persona l inju ry if yo u
must c han ge the engine oil in your ve hicle
yo urself:
- Wea r eye p rotection .
192
-
-To reduce t he risk of burns from hot engine
oil, let the engine coo l down to the touch.
- W hen removing the o il drain p lug with your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oi l from running down your
arm .
- Dra in the oil into a c ontainer designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it we ll out of
the reach of chi ld ren .
- Continuous contact w it h used eng ine oi l is
ha rmf ul to your skin. Always protect you r
skin by washi ng oil off tho roughly wi th soap
a nd wate r.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your e ngine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changi ng your oil, first make su re
you know where you ca n prope rly dispose of
the used oil.
- Always dispose of used eng ine oil properly.
Do not d ump it on garden so il, wooded
areas, in to op en st reams o r down sewage
drai ns.
- Recycle used engi ne oil by taking it to a used
eng ine oi l collect ion fac ility in yo ur area, o r
c ontact a service station.
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 sealed and genera lly re­
q u ires little attention.
The cooli ng sys tem has been filled at the f actory
wi th a permanent coolan t which does not need to
be changed. The coolant consists of a mixtu re of
jll,,

"' N

rl I.O
"' N
"' rl
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.

¢ 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

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

soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused . Always
dispose of used coolant while observ ing a ll
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt. The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary e lectr ic radiator fan * switches on and
off depending on coo lant temperature and other
veh icle operating conditions.
Afte r you switch the engine off, the a uxiliary fan
can cont inue running for up to 10 minutes -even
with the ignition off. It can even switch on again

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

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

Winter ope rati on
During the winter months, battery capacity tends
to decrease as temperatures drop. This is because
more power is also cons umed w hile starting, and
the headlights, rear window defogger, etc., are used more often.
Avoid unnecessary power consumption, particu­ l arly in city traffic or when traveling only short
distances. Let your authorized Audi dea ler check
the capacity of the vehicle battery before winter sets inc:>
page 198. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it will not freeze. This will prevent it
from being damaged and having to be re­
placed.
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 compa rtme nt,
