Instrument s and warning /indicator lights 11
/! WARNING
- Always observe the warning in
¢ page 205, Engine compartment, be­
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the radiator . At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engin e RPM
(revolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod . Before reaching this area, move these­
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ fig. 3 should
only briefly be in the red zone: you cou ld
damage your engine! The beginning of the
red zone varies depending on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

!S ET i
button. You can perform an Auto-Check se­
quence when the vehicle is stationary and the
ignition is turned on or when the vehicle is
moving slower than 3 mph (5 km/h) .
In addition, the number of keys initial ised fo r
your vehicle is displayed.
L2 3/3 means that
three keys have been initialised. This feature
enables used car buyers to make sure they
have received all of the keys.
If you are given only two keys, for instance,
you should take the vehicle and the existing keys to an Audi dealer to have the missing key
disabled.
It is also important to notify your in -
surance company about the loss .

8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 207,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 217, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld
overhea t and cause a fire.
CD Note
- Be aware that just o ne tank filling with

(0 Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in
over­
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
.,. Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
con sump tion .
C heck your oil each time you fill your tank.
The amount of oil used is related to engine
l oad and speed.
I t is normal for the oil consumption o f a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You mus t drive yo ur vehicle abo ut 3,000 miles
(5,000 kilometers) be fo re yo u can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output.
(]) Note
-Have yo ur vehicle maintai ned properly
and in accordance with the service re c­
ommendations in your War ran ty
& Mai n­
tenance bookle t. Lack of proper mainte ­
nance as well as imp roper use of the
ve­
hicle will impair the function of the
emission control system and could lead
to damage. -
Do not alter or
remove any component of
the Emission Control System unless ap­
proved by the manufacturer .
- Do not alter or
remove any device, such
as heat shie lds, switches, ignition w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
oper ating temperature to
reduce fuel consumpt ion and nox ious em is­
s ions effectively.
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 m iles
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 engine is at its prope r operating tempera­
tu re and fuel economy has reached a normal
level. So you can see that yo u should avo id
short trips whenever poss ible.
T he
outside temperatur e is also cr it ical in t his
regard. Your car consumes more fue l in the
winter tha n in the s umme r.

208 Fuel supply and filling your fuel tank
-Anti -knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving .
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identif ied.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties .
- If you experience a loss of fuel economy
or driveab ility and performance prob­
le ms due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (B io-ethanol)
App lies to veh icles : w ith flex ible fue l en g in e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap.
Vehicles with flexible fuel engines may be op­
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95) . The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption w ill increase when us­
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha­
nol , a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures. This fue l evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the o il level.
CD Note
- Never fill with methanol o r with a higher
percentage of b io-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fuel tank complete ly with un­
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fue l tank comp letely with unleaded pre­
m ium grade gasoline and dr ive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists .
