As long as the need le remains at the lef t en d of the gauge, the engine
s till has not reac hed its operati ng te mperature . Avoid hig h eng ine
speeds, heavy engine loads a nd heavy throttle.
Normal temperature
W hen the eng ine has reached its operating temperature, the need le
w ill move into the middle of the gauge and rema in there . If the
engine is working ha rd at high outsi de temperatures, the needle may
tur n further to the rig ht. Thi s is no cause fo r concern as long as the _F_
wa rning light in the i nstr ument cluster does not ill uminate.
Wh en the _;_ w ar ning light sta rts to fla sh, thi s can mea n one of two
things : either the coolant
temperature is too h igh, or t he coolant
level is too low => page 32.

On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 9 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your eng ine system
has been assigned a code. In case of a malfunction, the component
wi ll be identified and the fault stored as a code in the control module
memory .
The MIL lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system.
If the Light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed~
page 222.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood release lever~ fig. 9. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models )
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 11, fig. 5 is part of the On-Board Diagnostic (OBD II) system.
T he warn ing/indicator light illum inates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
ma lfunction ing. For more information~
page 20, "E lectronic speed
limiter" .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate~
page 222 . •
Electronic speed limiter
Your vehicle may be factory equ ipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle . To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, your vehicle a lso has an electronic speed limiter . The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information~
page 259, "Speed rating
(letter code)".

If the generator warning/indicator light shou ld also illuminate
=> page 15, t hen t he fan belt m ay be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons , pa rk at a safe distance from mo ving traffic, turn off the
engine and turn on the hazard warning lights=>
page 59, "Emer­
gency flasher
A. ".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping .
• The engin e compartment of any vehicle i s a dangerou s ar ea .
Before you p erform any work in the engine compartment , turn off
the engine and allow it to cool. Follow the warning sti ckers
=> page 218 , "Engine compartment ".

Shut the eng ine down .
- Check t he eng ine oi l level=>
page 231 .
-Contact your authorized Aud i dea le r for assis tance i f
necessary .
Engine o il level too low
If the eng ine oi l leve l is too low , top off oil to t he p roper level
=>page 232.
Engine oil level OK
If the 't'!::;r. symbol starts flashing again even thoug h the engine oil
level checks O K on t he d ipstick,
do not start driving again and do not
let the engine run at idle .
Instead, contact you r authorized Audi
dealer fo r assis tance.
[ i ] Tips
• The engine oil pressure symbol 'I=:?: is not an indic ato r for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular intervals , preferably each t ime you refuel, and
always before going on a long tr ip .
• The yellow oil level warning indication requires oil refill or
workshop service without de lay . Do not wait until the red oil pre s­
s ure warning symbol~ starts to flash before you respond to the
low oil level warning _, . By then, your engine may already have
s uffered serious damage. •
Applies to vehicles: with manual trans miss ion
-;y Clutch pedal
T he indica tor lig ht illuminates if you do no t press t he cl utch pedal
when starting the engine . For safety reasons, the engine will only
sta rt when the clut ch pedal is pressed. •

Some states in the USA require permits to purchase diesel fuel. Check
with your State Motor Vehicle Department.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before traveling to other countries .
Winter operation
At temperatures below 20° F (- 7° C), Diesel fue l No. 2 loses its fluidity
due to wax separation, which may clog the fuel filter or tank filter and
keep the engine from running.
T o help the filter from being clogged by wax, the fuel fi lter in your
vehicle is automatically preheated. Preheating the fuel filter makes
operat ion of your vehicle possib le with Diesel fuel No. 2 down to -
10° F (-24° C).
If you expect temperatures below 5° F (-15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is suffic iently w interized for the
prevailing and expected temperatures.
If not winte rized or insuffic iently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during the
warm-up period in winter.
It is also normal when whitish -blue smoke
comes out of the tailpipe after start ing and during warm-up. The
amount of smoke depends on the outside temperature.
Do not let your diese l engine id le unnecessari ly after a cold start.
Driving off slowly will shorten the warm-up period.
& WARNING
• Never use "starting assist fluids." They may be potentially
explosive or cause a "run-away" engine condition. This could
result in serious engine damage and personal injury.
• Never use fuel line anti-freeze offered for gasoline engines.
Safety first
0 Note
• Your diesel engine has been specifically designed to operate only
on Ultra Low Sulfur Diesel fue l. Therefore, never use home heating oil
or regu lar gaso line. The properties of these fuels may cause serious
damage to the fuel injection system and to the engine. Using these
fue ls can cause expens ive eng ine repairs and will also adversely affect
your New Vehicle Limited Warranty.
• If diesel fuel should get on any rubber hose, it must be wiped off
immediately. Then wash the contaminated hose portion with soap
and warm water. Do not allow diesel fuel to rema in on connecting
hoses. They may deve lop leaks and cause serious damage. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fue l filler flap.
If the power locking system should fa il, you can still open the flap
manually - for detai led instructions see=>
page 224.
You ca n find the fuel tank capacity of your vehicle in Technical Data
=> page 296 .
The label on the inside of the fue l filler flap tells you the correct fuel
for your veh icle. For more information about fuel specifications, see
=> page 219.
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protect ing the environment,
please follow this refueling procedure carefully. .,,

& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty,
may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc., be very careful
and always observe local and state laws regarding the use, trans ­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 - 86).
0 Note
Never drive your vehicle until the fuel tank is completely dry. The
irregular supply of fuel can cause misfiring. Gasoline could enter into
the exhaust system and damage the catalytic converter. •

& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back
in your vehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke o r have an open flame anywhere
in or near your
vehicle when refueling or filling a portable fuel container .
• For your safety , we strongly recommend that you do not travel
with a portable fuel container in your vehicle . The container, full
or empty may leak and could cause a fire , especially
in a crash.
• If, under exceptional circumstances, you must transport a
portable fuel container , please observe the following:
- Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or
on the trunk ). Static electricity can build up while filling and
can ignite fuel vapors causing a fire.
Safety first
& WARNING (co ntinued )
-Alw ays place a portable fuel container on the ground before
filling .
- Always keep the filler nozzle completel y inside the portable
container before and during filling .
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. Th is will help
prevent static electricity from discharging and cause a fire .
- Never spill fuel inside the veh icle or luggage compartment.
Fuel vapors are highly flammable.
- Always observe local and state/provincial laws regarding the
use, storage and tran sportation of fuel containers .
- Make certain the fuel container meets industry standards
(ANSI/ ASTM F8S2-86).
