9:::1: Engine oil pressure
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se­
vere damage to the engine.
• Turn off engin e! Oil pressure too low
If the indicator light t urns on and the message
appears, the oil pressure is too low.
• Pull
off the road.
• Stop the vehicle .
• Turnoff the engine.
• Check the engine oil level ¢ page 195.
• If the engine oil level is too low, add engine oil
¢ page 195. Make sure that the o il pressure
warning symbol. appears no longe r in the
display before you start dr iving again.
• If the engi ne oil leve l is correct a nd the ind ica­
tor light st ill turns on, turn the eng ine
off and
do not continue driving . Seek p rofess ional as ­
s istance .
(D Tips
- The engine oil pressure symbol. is not
an indicator for a low engine oil level. Do
not rely on it. Instead , check the oil level in
your engine at regular intervals, prefe rably
each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay. Do not wait until the red oil pressure warning. starts to flash before
you respond to the low oil leve l warning
Ill . By then , your engine may already have
suffered serious damage.

Driving and th e environment
(D Tips
- Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline¢ page 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of the vehi­
cle. The cataly tic converter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The ex clusive use of u nleaded fuel is critically im­
por tant for the life of the catalyt ic converte r and
p roper functioning o f the engine.
A WARNING ,..___ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park o r operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter or
heat shields. During driv ing, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank fill ing with
le ad·
ed
fue l w ill already ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine co uld m isfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lyt ic converter to overheat.
- Do not turn
off the ignition while the vehicle
is moving .
- Do not continue to operate your veh icle un­
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re­
sult in overheating of the conve rter, requ ir­
ing its replacement.
- T o assure efficient operation of the Emission
Cont ro l System:
- Have your vehicle maintained properly and
in accordance with the se rvice recommen­
dations in yo ur Warranty
& Maintenance
booklet.
- Lack of proper maintenance as we ll as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion C ontrol System is op­
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme ll under some op­
erat ing states. This depends on the sulfur
content of the fuel being used. Us ing a d iffe r­
ent brand of fue l may he lp, or fi llin g the tank
wi th lead-free s uper grade gaso line.
Shutting down vehicle
If you would like you r vehicle to remai n inope ra­
tive for a longer period of time, con tact an Audi
o r other spec ia liz ed dealer. They can adv ise you .,.

Driving and th e environment
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.,. Have your vehicle serviced at regula r intervals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically. The condition of
your vehicle not only affects its safety and ability to hold its value, it also affects
f uel c onsump­
tion .
C he ck you r oil e ach t ime you fill you r ta nk .
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
g ine to reach its lowes t va lue after a cer tain mile ­
age has been d riven .
You must d rive you r vehicle about 3,000 miles
(5 ,000 k ilometers) before you can properly as­
sess o il cons umption .
This a lso applies to fuel consumption and engine
output.
(D Note
- Have your vehicle maintained properly and
in accordance w ith the service recommenda­
tions in you r Warra nty
& M aintenance book­
l et . Lack of p roper m aintenance as well as
i mprope r use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not a lter or remove any component of
the Emission Cont ro l System unless ap­
proved by the manufacturer.
- Do not a lter o r remove any dev ice, such as
heat shie lds, switches, ignition wires,
va lves, which are designed to protect your
vehicle's Emiss ion Control System and other
i mportant veh icle components.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid dr iv ing short distances with a cold
eng ine .
The eng ine and catalytic converter have to reach
their opt imal
oper atin g temperature to reduce
fuel consumpt ion and noxious emissions effec­
tively .
Just after starting, a co ld engine in a mid-s ize car
on ly achieves a fuel economy of 6-8 mi les per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . After about
2.5 miles (4 km), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avo id short trips whenever
poss ible .
The
out side t emp eratur e is also cr itical in th is re­
gard. Your car consumes more fuel in the winter
than in the summer.

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 .
- Fo r more informa tion abo ut engine oi l that
has been approved for your vehicle, please

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 internal 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
194
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 195 . Top off the oil at your ear liest con ­
venience ¢page 195.
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 191.
@ 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 .,.

level indicator is near "min"
r:::>page 195
Depending on the way the vehicle is driven and
the operating conditions, oil consumpt ion can be
up to a 1/2 quart per 600 miles (O.S liter per
1,000 km) . Consumption may be higher within
the first 3,000 miles (S,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 warn ing appears in
the instrument cluster. Add oil¢
page 195.
If the hood has been opened, the current oil
level is shown in the instrument cluster the
next time the ignition is switched on.

er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This m ixture both
assures the necessary frost protection and pro­
tects meta l components in the engine's cooling
system from corrosion and scal ing . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water .
The p ropor­
tion of coolant addit ive must be at l east 50 %

to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant cou ld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory fo r temperatures dow n to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coo lant, use a mixture of water

(D Note
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in your
vehicle is suffic ient to meet the cli mate con­
dit ions. This is especially important if you
li ve in a region where the win ter is extreme­
l y co ld. If ne cessary, i ncrease the proport ion

- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. This
coolant additive is ava ilable at authorized
Audi dea lers. Other types of ant ifreeze can
significant ly reduce co rrosion protection.
Checking and Fillin g
The resulting corrosion can ca use a loss o f
coolant and serious engine damage.
- Do not add any type of rad iator le ak sealan t
to your vehicle's engine coolant. Adding ra­
diator repai r fluid may adverse ly affect the
function and performance of your cooling
system and could result in damage not cov­

s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A 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 coo l
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag .
-Turn the cap slowly and very carefully in a
counter-clockw ise d irection while applying
light, downward pressure on the top of the
cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or hot eng ine parts . Under ce rtain conditions,
the ethy lene g lycol in engine coolant can
catch fire.
{il) Note
Do not add any type of rad iator leak sealant
to your veh icle's engine coolant . Adding radia­
to r repair f lu id may adverse ly affect the func­
tion and performance of your cooling system
and could resu lt in damage not covered by
your New Vehicle Limited Warranty.

Replacement engine coo lant must conform to ex­
act specifications ¢
page 196, Coolan t.
We recommend using only coo lant additive Gl2 +
+ , Gl3
or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter unt il you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible .
If you have lost a considerab le amount of cool­
ant, then you should add cold antifree ze and cold
water only when the engine is cold.
Always use
new engine coo lant when refilling.
Do not fil l coolant above the "MAX " mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
