C hanging the engine oil
The engine oil and o il fil te r must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls spe cified in your vehicle 's War­
ra nty
& Main ten ance booklet. Do not ex ceed
these in tervals - harmful depos its from ol d
engine o il can reduce engine performance an d
can lead to expensive engi ne re pairs.
C hanging the o il at th e recommen ded i nte r­
v al s is so very impor tant because t he lub ric at ­
ing p roperties o f oi l decrease gra dually du ring
norma l vehicle use . If you are not sure when
you have yo ur oil changed, ask yo ur aut ho r­
i z ed A udi Service Advisor.
Unde r some ci rc u ms tances the engine o il
should even be change d mo re frequently .
C hange o il more often if you drive mostly
short d istances, ope rate the vehicle in d usty
areas or mostly under stop-and-go traffic con­
d it ions, or when you use your veh icle w he re
tem peratures stay below freez ing poin t fo r
l ong periods .
Detergent addit ives i n the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a shor t time . This is no rma l and is not
a reason to change the o il mo re often tha n
r e co m men ded.
Damage or malfunctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine o il
that complies with Audi oi l standard
VW 502 00 (vehicles wi th gasoli ne e ngine) or
VW 507 00 (ve hicles with diese l engi ne) . Yo ur

Engine oil consumption
To prov ide effective l ubr ication and cooling for
i nter na l eng ine parts, a ll interna l combustion
engi nes use some o il. Oil consumption va ries
from eng ine to engi ne and may cha nge over
t h e life of the engine. Engines tend to use
more o il du ring t he b reak-in pe riod tha n they
do afterwa rd, w hen oil c onsum ption ha s sta­
b ilized. Dependi ng on the w ay the vehicle is
driven and the operati ng conditions, oil con ­
s u mption can be up to 1 q uart per 1, 200
miles (1 liter per 2,000 km) . Consumption
may be higher within the first 3,000 m iles
(5,000 km) .
Un der normal con ditions , the rate o f oi l con­
s u mption depen ds on o il quality as well as vis ­
cosity, engine spee d (rpm), outs ide tempera­
ture, road conditions, the amount of oil dil u­
t io n caused by condensed water or fue l resi ­
du e, and ox ida tion of the o il. Oil co nsu mp tion
may incr eas e with eng ine w ear ov er time, un ­

We urge you to check the engine oil level at
regular intervals, preferably every time you
fill the fuel tank, and always before a long
trip.
The oil pressure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while driving (above 1500 rpm), a
buzzer will sound. It indicates that the oil
pressure is too low . Stop the engine immedi·
ately, check the engine oil level and add oil if
necessary. If the engine oil level is normal,
but the light continues to flash, do not keep
driving or let the engine idle, as damage may
occur .

266 Check ing and filling
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
_& WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARN INGS
¢ .&. in Working in the engine
compartment on page 258.
(D Note
- Befo re winter se ts in, have the coolant
checked to see if t he coolant addit ive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely co ld. If necessary, in­
crease the proport ion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­ ditive G12++ or G13 for your vehicle.
Th is coo lant add itive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro ­
sion can cause a loss of coo lant and se­
r ious engine damage.
- Do not add any type of radiator leak sea l­
ant to your vehicle's engine coolant.
Adding rad iator repair fluid may adve rse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Wa rranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

care full y twist the cap counter-clockwise
¢,&. .
.,. Read the engine coolant level in the open
coolant expansion tank. W ith a cold eng ine,
the coolant level should be between the "min" and "max" markings. When the en­
g ine is wa rm, the level may be slightly above
the "max" mark ing.
T he locat ion of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 260.
To obtain an accu rate 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 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coo lant level sensor, we still rec­
ommend you check the coolant level from
time to t ime.

Coolant loss
Coolant loss may indicate a leak in the cool ing
system . In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi d ealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to coo l
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 wh ile ap ­
plying light, downward pressure on the
top of the cap .
- To avoid be ing burned, do not spill ant i­
freeze or coolant on the exhaust system

t ions, the ethy lene g lycol i n engine cool­
an t ca n ca tch fire.
(D Note
Do not add any type of rad iator leak seal­
ant to you r vehicle's eng ine coolant. Add­
ing radiator repair f luid may adversely af­
fec t the function and pe rformance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty .

268 Checking and filling
-If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire . Excess cool-
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze
c:::> page 265 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to the temperature of the
coolant.
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 aux iliary
fan can continue running for up to 10 minutes
- even with the ignition 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
t he engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunligh t.
_&. WARNING
- To reduce the risk of personal injury nev­
er 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 au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab ility over a longer period
c;, page225.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the
engine .
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
starting, and the headlights, rear window de ­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before w inte r sets in
¢ page 271. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
prevent it from being damaged and having
to be replaced.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located under the driver 's seat.
Before you check anyth ing under the driver 's
seat,

308 Emergency situations
Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to perform these operations.
Starting by pushing or
towing
Q;) Note
Your vehicle is equipped with an automatic
transmission. Consequently, the engine
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specifications.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible. -
A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es . Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery .
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 248, Engine com­
partment.
@ Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,.
