A WARNING
- Always observe the warning in
c::> page 212 , 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
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
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler 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 co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
I f engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
@) Note
The tachometer needle@c::> 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.

interval.
0 Note
- Only reset the oil change d isplay when
you have completed an oil change.
-If you disconnect the battery terminals,
no calculat ions can be made for the serv­
ic e interval display during this tim e and
no service rem inder will appear. Remem­
ber that observing the proper service in­
terva ls is vitally important to extending
the life of your vehicle, particularly the

(D Tips
The informat ion in the Service Reminder
remains stored even when the vehicle bat­
tery is disconnected.
On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
This indicates that the MIL is work ing proper­
l y.
Driver information display 29
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing , a malfunction may exist in the engine sys ­
tem.
If the light illuminates, the catalytic con­
verter could be damaged.
Continue d rivin g
with reduced power (avoid­
ing su sta ined high speeds and/or rapid accel ­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
li miter may also be malfunct ioning. For more
information
c;,page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:;, page 210.
On-Board Diagnostics
Fig. 18 Location of Data Link Connector (D LC)
On-Board Diagnostics monitors the compo­
nents of your emission contro l system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memo ry .
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem. If the light illumi nates afte r a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed

In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe­
c ial diagnostic equipment (generic scan tool

~ Automatic transmission: Step on the brake
peda l and move the se lector lever to the P
or N position .
~ Press the key c::> fig. 97 -the eng ine will
start.
Sw itching the i gnition on /off
If you wou ld like to switch the ignition on
without sta rting the engine, follow t hese
steps :
~ Insert the key into the ignition lock .
~ Press the key briefly without pressing the
clutch peda l (for manual transmissions) or
the brake peda l (for automatic transmis­
s ions) .
~ To switch the ignition off, press the key
again .
When starting the engine, major e lectr ica l
loads are switched off temporarily .
You can on ly remove the key with the ignition
switched off.
If the engine sho uld not sta rt immedia tely,
the starting process is automatically stopped
after a short time. Repeat starting proced ure .
A WARNING
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never remove the ign ition key from the
ignition look while the vehicle is moving.
Otherw ise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- Always take the key with you whenever
you leave your vehicle . Otherwise, the
engine could be started or e lectr ical
equipment such as the power w indows
cou ld be operated. This ca n lead to seri­
o us inj ury.
- Never leave ch ild ren or persons requiring
assistance unattended in the veh icle. The
doors can be loc ked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency. Depend ing
on the time of year, people inside the ve-
On th e ro ad 83
hicle can be exposed to very high or very
low temperatures.
(D Note
Avoid high eng ine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating tempe rat ure -other­
wise you r isk eng ine 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.
@ Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehi-
cle <=:>
page 34.
-After starting a cold engine, there may
be a brief period of increased no ise be­
cause the oil pressure must first bu ild up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If you leave the veh icle with the ignition
switched on, the ign it ion w ill switch off
afte r a certa in per iod of t ime . Please
note that ele ctrical equ ipment such as
exterior lights will sw itch off as well
when that happens .
