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.

(D Note
- Fuels containing a high pe rcentage of etha­
no l such as ESQ and E85 may only be used in
vehicles with f lexible fuel engines. Using
high ethanol fuel in veh icles not equ ipped
with flexible fuel engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for wh ich the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those spec ified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle o r the Emission Cont ro l
System Warranties.
- If you experience a loss of fue l economy o r
driveability and pe rformance problems due
to the use of one of these f uel b lends, we
r ecommend that yo u switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles w ith f lexible fuel engines may be operat­
ed with bio-ethanol fuels such as E85 (85% e tha ­
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95) . The vehicle may also be operat­
ed with a m ixt ure of these fuels.
Fu el and R efu elin g
Your f uel consumption wi ll increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy contained per unit vo lume in ethano l.
Warming up the fle xible fuel engine in low
t e mperatu res
Due to the chemical composition of b io-ethanol,
a certain amount of fue l ends up in the engine oil
when driving short distances in
very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up .
II Please w arm up eng ine .
If the driver message appears in the instrument
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
-Never fill with methano l or with a h igher
percentage of b io-ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fue l can cause damage to the engine or to
the fuel system.
- If you use on ly E85, it is recommended to
fill the fue l tank complete ly w ith unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes­
itat ion driveab ility problems, fill the fuel
tank complete ly w ith unleaded premium
grade gasoline and drive it normally unt il
the gaso line is used. See your author ized
Audi dea ler if the problem pe rsists.
- Inform your author ized Audi dealer that you
are operating or have operated the vehicle
w ith E85.
- Read and follow the information and t ips
about gasoli ne
c::> page 186 .
(D Tips
It may take longer to start the engine when
the outs ide temperature is
very cold. If possi­
ble, use winte rized fue l if tempe ratu res are
below free zin g.

Checking and Filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam or
coolant escaping from the engine compart­
ment . Wait until no steam or coolant can be
seen or heard before carefully opening the hood.
- Keep children away from the engine com ­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly .
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system
is pressurized and hot coolant could spray
out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary :
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment could start a fire.
- Keep an approved fire extinguisher imme­
diately available .
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
192
to "P" (Park); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from getting
caught in the radiator fan, V-belts or other
moving parts, or from contacting hot
parts . Tie back hair before starting, and do
not wear clothing that will hang or droop
into the engine.
- Minimize exposure to emission and chemi­ cal hazards
