Instrument s and warning /indicator lights 11
,&_ WARNING
- Always observe the warning in
¢ page 208, 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 engine 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@¢ page 10,
fig . 3
shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Starting the Auto-Check sequence
The Auto-Check system constantly monitors
certain individual functions and components
of the vehicle when the ignition is turned on
and when the vehicle is moving .
With the ignition turned on, you can start the "Auto-Check sequence" by pressing the
! SET !
button . You can perform an Auto-Check se­
quence when the vehicle is stationary and the
ignition is turned on or when the veh icle is
moving slower than 3 mph (5 km/h).
In addition, the number of keys init ialised for
your vehicle is disp layed .
L2 3/3 means that
three keys have been initialised. This feature
enables used car buyers to ma ke 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 dea ler to have the missing key

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.
Convenience key
Starting the engine
Applies to vehicles: with convenience key
The I STAR T ENGINE ST OPI button switches
the ignition on and starts the engine.

without pressing the clutch pedal (for man ­
ual transmissions) or the brake pedal (for
automatic transmissions) .
.. To switch the ignition off, press the button
again.
On the road 75
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 temporarily.
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 norma l 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.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
-After starting a cold engine, there may
be a brief period of increased noise be-
cause the oil pressure must first bui ld up
II-

(D 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
authori zed Audi dealer helps 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
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte ­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
Driving and environment 195
- 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 shields, switches, ignition wires,
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 rela tively
high on short trips .
.,. Try to avoid driving short distances with a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
operating temperature to
reduce fuel consumpt ion and noxious emis­
sions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 miles
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 proper operat ing tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possible.
T he
outside temperature is also cr itical in th is
regard. Your car consumes more fue l in the
winter than in the summer.

-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 stations 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 flexible fuel en­
gines. Using high ethanol fuel in vehicles
not equipped with flexible fuel engines
can cause severe engine damage.
- Methanol fuels which do not meet 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 identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility 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 driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
Vehicles with flexible fuel engines may be op­
erated with bio-ethanol fuels such as E85
Fuel supply and filling your fuel tank 211
(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 will increase when us­
ing bio-ethanol fuels 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 bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel 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 oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- Read and follow the information and tips
about gasoline¢
page 210.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
Although gasoline grades differ from one manufacturer to another, they have certain
things in common . All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER ..,.

216 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully 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 auxili­ ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant 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 electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury 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 trans­
mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing 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
chemical hazards~&, .

(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the

Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 192) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 219
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
1\1 in the instrument cluster lights up , you
sho uld check the oil leve l as soon as possib le

222 Check ing and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-basedcoolant additive G 13 antifreeze with
anticorrosion add itives (SO% for USA mode ls;
60% for Canadian models). This mixture both
assures the necessary frost protection and protects metal components in the engine's
cooling system from corrosion and scaling. It
a lso raises the boiling point of the coolant .
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
p ro po rti on of c ool ant add it iv e mu st b e at
lea st 50 % but not mo re th an 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
_& WARNING
Before yo u check anything in the engine

(]) Note
-
- Before winter sets in, have the coolant
checked to see if the coo lant additive in
your vehicle is s uffic ient to meet the cli­
mate cond it ions . Th is is especially impor­
tant if you live in a region where the w in­
ter is extremely cold . If necessary, in- crease the p
roportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing on ly coolant ad­
d itive G12++ or G13 for your veh icle .
This coolant additive is availab le at au­
thor ized Audi dealers. Other types of
ant ifreeze can s ignificantly reduce cor­
rosion pro tection. The resulting cor ro­
sion can cause a loss o f coolant and se ­
rious engine damage.
- Do not add any type of rad iator leak seal­
ant to yo ur vehicle's engine coolant .
Adding radiator repair fl uid may adverse ­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Veh icle
