¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 256, before 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
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine 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 cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops 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 (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .

not press the accelerator pedal.
.,. Re lease the ignition key once the engine
sta rts. The starter must not continue run­
ning.
A cold engine may sound loud after it has
been started . This is due to the hydraulic
va lves building up oil pressure. This is normal
and is not a need for concern.
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine abo ut 30 seconds later.
Glow plug system*
Diesel engines are equipped with a glow plug
system whose preheating t ime is controlled by the coo
lant and outs ide temperature . Start
the engine
immediately after the glow plug
indicator light
II switches off.
The glow plug indicator light will only illumi­
nate for approximate ly 1 second when the en­
gine is warm or the outside temperature is
higher than 46 °F (8 °C). That means you can
start the engine
immediately .
A WARNING
-Never start or let the engine run in a con-
fined or enclosed area. Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odorless gas . Carbon mon­
oxide can be fatal if in haled.
- Never leave the engine idling unattend­
ed. An unattended veh icle w ith a runn ing
engine poses a danger of personal injury
or theft .
(D Note
- Avo id high engine speeds, fast accelera­
tion or heavy engine loads while the en­ gine is still cold. This could damage the
eng ine .
- Th e engine cannot be started by pushing
or towing the vehicle .
@ For the sake of the environment
To avoid unnecessary engine wear and to
reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after starting your
vehicle. Maintain moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature.

Catalytic converter
Applies to vehicles: with gasoline engine
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 an environmentally sound manner .
... Always use lead-free gasoline c::> page 248,
Gasoline .
... Never run the tank down all the way to emp­
ty .
... Never put too much motor oil in your engine
c::> page 261, Adding engine oil 't=r..
.,. Never try to push-or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert­
e r and proper functioning of the engine.
& WARNING ,~
T he 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 or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.
Dri vin g and en vironm ent 231
-Do not exceed the correct engine oil level
c::> page 261.
- Do not drive until the fue l tank becomes
completely empty. The engine cou ld mis­
fire. Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle main tained properly
and in accordance w ith the se rv ice rec­
ommendations in your Warranty & Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle will impair
the function of the emission contro l
system and could lead to damage.
@) For the sa ke of the env ironment
Even when the Emission Control System is
operating properly, the exhaust gas can have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r clea ns itself automat ica lly under no rma l
driv ing cond itions. If the filter cannot clean it ­
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the

,8. WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especia lly true for vehicles with low­
slung chassis (sports chassis)* and fully load­
ed vehicles.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer . They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, maintenance and storage. Pay attention to additional information con ­
cerning the battery. Refer to
c::> page 266 .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec­
tion will give you some tips on how you can help the environment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
· Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
., Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac ­
celerating . If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
., Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the environment.
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail­
road cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld 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 .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
consumption.
Check your oil each time you fill your tank.
Driving and environment 233
The amount of oil used is re lated 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
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
t enance booklet. Lack of prop er mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l 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 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 relatively
high on short trips .
11-Try to avoid driving short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km), liJI,

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll 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 .
(D Note
-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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- 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 l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles : wit h gasoli ne e ng in e
A majo r concern among many auto manufac­
ture rs 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 g rades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
Fuel supply and filling your fuel tank 249
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
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
CD Note
Damage or malf unct ion due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULSD No. 2 meets the ASTM D97S.
Diesel fuel with concentrations of biodiesel
highe r than S % such as Bll, B2O or BlOO are
strictly prohib ited .
Se rv ice stat ion fuel pumps are labeled with
the cor rect fuel informat ion for easy recogn i­
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries .
ULSD No. 2 can become thicker in very cold
temperatu res, and this can impair the en­
gine's start ing and running. Depending on the
season, gas stations provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
CD Note
-Yo ur vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Therefore, never use gasoline, heating oil, other fuels or flow improvers. These
conta in substances that will severely
damage the fuel system and the engine . .,.
