,&_ WARNING
- Always observe the warning in
¢ page 209, 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
(r evolutions 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 a rea, 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.

7 4 On the road
(D 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

Switching the ignition on/off
If you would like to switch the ignition on
without starting the engine, follow these
steps :
.. Press the
!START ENGIN E STOP! button
without pressing the clutch pedal (for man ­
ual transmissions) or the brake pedal (for
automatic transmiss ions) .
.. To switch the ignition off, press the but ton
again. If
the engine should not start immediately,
the sta rting process is automatically stopped
afte r a short t ime. Repeat start ing procedure.
When sta rting the engine, major elect rical
loads are switched off temporar ily .
After a cold engine is started, there may be a
brief period of increased noise because oil
pressure must first build up in the hydrau lic
valve adjusters . This is norma l and not a cause
for concern .
.&_ 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 veh icle . Otherw ise, the
engine could be started or electrical
equ ipment 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
tr an smitter, preventing people from es­
caping from the veh icle 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 .
(D Note
-Avo id high engine rpm, full throttle and
heavy eng ine 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 build up .,.

196 Driving and en vironm ent
(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.

212 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 (Bio-ethanol)
Applies to vehicles: wit h flexible fue l e ngi ne
Vehicles with f lexible fuel engines may be op­
erated with bio-ethanol fuels such as E85 (85% ethano
l 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 wi ll increase when us­
ing bio-ethano l 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 bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . Th is fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster disp lay, 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
eng ine or to the fuel system .
- Read and follow the information and t ips
about gasoline¢
page 211.
Gasoline additives
A major concern among many auto manufac­
turers is carbon depos it build-up caused by
the type of gaso line you use .
Although gasoline grades differ from one manufacturer to another, they have certain
th ings in common . All gasol ine grades conta in
substances that can cause deposits to collect
on vital engine parts, such as fue l injectors
and intake valves. A lthough most gasoline
brands include add itives to keep engine and
f uel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For mo re information on TOP TIER .,.

-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:
Checking and filling 217
- 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~,& .

temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il 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.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals 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 book let . 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 t imely 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, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l 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 ox ida­
tion level of the oi l. 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 a ll 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
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le

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-based coolant additive G13 antifreeze with
anticorrosion additives (50% for USA models;
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
also raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35 °C)USA
- -40 °F ( - 40 °C) Canada.
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
¢ .&. in Working in the engine
compartment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in-
Checking and filling 223
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle .
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
