't:::7: Engine oil pressure
The red en gine oil pressure warning symbol
requires immediate service or repair . Driving
with a low-oil -pressure indication is likely to
inflict severe damag e to the engine.
• Turn off engine! Oil pressure too low
If th e ind ic a tor lig ht tur ns on an d th e me s­
sage a ppears, the oil press ure is too low .
~ Pull off the road.
~ Sto p th e ve hicl e.
~T urno ff th e e ngine.
~ Check the engine oil level <=> page 219.
~ If the engi ne oi l leve l is too low , add engine

~ If the en gine o il level is co rrec t and the in di­
cato r light still turns on, turn the e ngine
off
and do not cont inue driv ing . See k pr ofessi o­
na l assistance .
(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
Ill requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil level warning
Ill. By then, your engine
may already have suffered serious dam­
age.

without sta rting the engine, follow t hese
steps :
~ Insert the key into the ignition lock .
~ Press the key briefly without pressing the
clutch peda l (for manual transmissions) or
the brake peda l (for automatic transmis­
s ions) .
~ To switch the ignition off, press the key
again .
When starting the engine, major e lectr ica l
loads are switched off temporarily .
You can on ly remove the key with the ignition
switched off.
If the engine sho uld not sta rt immedia tely,
the starting process is automatically stopped
after a short time. Repeat starting proced ure .
A WARNING
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never remove the ign ition key from the
ignition look while the vehicle is moving.
Otherw ise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- Always take the key with you whenever
you leave your vehicle . Otherwise, the
engine could be started or e lectr ical
equipment such as the power w indows
cou ld be operated. This ca n lead to seri­
o us inj ury.
- Never leave ch ild ren or persons requiring
assistance unattended in the veh icle. The
doors can be loc ked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency. Depend ing
on the time of year, people inside the ve-
On th e ro ad 81
hicle can be exposed to very high or very
low temperatures.
(D Note
Avoid high eng ine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating tempe rat ure -other­
wise you r isk eng ine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin dr iv ing immediately. This
reduces unnecessary emissions.
@ Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehi-
cle <=:>
page 35.
-After starting a cold engine, there may
be a brief period of increased no ise be­
cause the oil pressure must first bu ild up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If you leave the veh icle with the ignition
switched on, the ign it ion w ill switch off
afte r a certa in per iod of t ime . Please
note that ele ctrical equ ipment such as
exterior ligh ts w ill sw itch off as well
when that happens .

CD Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine
is switched off- there is a risk of damaging
the engine . Allow the engine to run at idle
for about two minutes before switching it
off.

If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
When starting the engine , major electrical
loads are switched off temporari ly.
After a cold engine is started, there may be a
brief period of inc reased noise because oil
pressure must first build up in the hydraulic
valve adjusters. This is normal and not a cause
for concern.
A WARNING
- Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .
CD Note
-Avo id high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature - other­
wise you risk engine damage.

218 Checking and filling
temperatures stay below freezing point for long periods.
Detergent additives in the oil w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
Damage or malfun ctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a timely manner.
Eng ine 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 ing of internal engine components, all in­
ternal combustion eng ines consume a certain
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specif ied break-in period (see
¢
page 195) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the oxida­
tion level of the oil. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With all these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
Ill in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 219. Top off the oil at your earliest
convenience ¢
page 219.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
compartment on page 214.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­ erably each time you refuel, and always
before going on a long trip.
- If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
m ind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dea ler has instructions about how to
measure oil consumption accurately.
-

222 Check ing and filling
level should be between the "MIN" and
"MAX" markings. When the engine is warm,
the leve l may be slightly above the "MAX"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
c:> page 216.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
c:> page 17will
b link until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sensor, we still rec ­
ommend you check the coolant leve l from
time to time.
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 A udi dealer.
It is not
enough merely to add coolant.
I n a sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is unde r 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 cool
dow n.
- Protect yo ur 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
'
or hot engine parts. Under certa in cond i­
tions, the ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not a dd any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add ­
i ng radiator repa ir fl uid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com­
partment, always read and heed all WARN­
