Engine coolant temperature gauge
The engine coo lant gauge ~ page 10, fig . 3 @
only wor ks when the ign ition is on. To prevent
damage to your engi ne, please note t he fo l­
lo wing important points :
Engine cold
As long as the need le rem ains a t the left end
of the gauge, the engine s till has not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy e ngine loads and heavy throt­
tle.
Normal temperature
When the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . war ning light i n the inst rument cluster
does not illuminate .
When the. warning light starts to f lash,
th is can mean one of two things: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ~ page 31 .
A WARNING
--Always obs erv e the warn ing in
~ page 17 2, Engine compar tment be ­
fore opening the eng ine hoo d and check­
ing the eng ine coolan t leve l.
- N ever ope n the eng ine hood if you see or
hea r ste am, or if you see e ngine c oo la nt
dripping from t he en gine compar tment .
You could burn yourse lf . Let the engi ne
coo l off fi rst so that you can not hear or
see any steam or engine coo lant.
(D Note
- M ounting ad ditiona l lights or accessories
in front of the air inlets reduces the coo l­
ing effect of t he radiato r. At high o utside
tempe rat ures or h igh engine load, the
eng ine could overheat.
- The front spoiler has been designed to
properly d istribute the cooling a ir when
the vehicle is movi ng. If the spoiler is
damaged, this could reduce the coo ling
e ff ect a nd the eng ine could then ove r­
heat . As k yo ur au thori zed A udi deal er for

Instruments and warning/indicator lights 15
-The light illuminates when the folding top
opens or closes .
- It flashes if one of the conditions for auto­
matically lowering or raising the convertib le
top is not met and the switch to actuate the convertible top is pressed.
- The light i lluminates when the convertib le
top is opened or closed
incompletely.
nl /J Electronic stabilization program
(ESP)
If the G1 i ndicator lamp blinks while dr iv ing,
the ESP or ASR (Ant i-S lip Regulation) is active­
l y regulating.
If the G1 indicator lamp illuminates, the sys ­
tem has sw itched the ESP off. In this case, you
can switch the ignition off and then on to
switch the ESP on again. The system is func­
tioning completely whe n the indicator lamp
switches off .
I f the
I indicato r lamp illuminates, the ESP
was switched off with the
[ru bu tton.
ESP/ ABS fault! See owner's manual
If the G1 indicator lamp and the ll] ABS indi­
cator lamp illuminate and the dr iver message
appears, the ABS or e lectronic differential lock
is malfunctioning. This also interrupts the
E SP . The brakes st ill function with the ir nor­
mal power, but ABS is not active.
Drive to your authorized Aud i dea ler immedi­
ately to have the malfunction corrected .
For more information about the ESP
¢page 148.
~ Malfunction Indicator Lamp (MIL)
The Malfunction Ind icator Lamp (MIL) is part
of the On-Board Diagnostic (OBD II) system .
The symbol
rfl lights up when the ignition is
turned o n and will turn off after the engine
has started and ha s settled at constant idle
speed. This ind icates that the MIL is working
p roperly.
The warning light illuminates when there is a
malfunction in the engine e lectronic system. Contact
your authorized Audi dea ler and have
the malfunction corrected .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
¢page 176.
For more information ¢ page 28.

electrically ret ra ctab le rea r spo ile r.
Additional informat ion about the e lectr ically
retractable rear spoiler ¢
page 150.
¢¢Turn signals
The indicator light blinks when you use either
turn signal.
Whenever you use the left II or the right II
turn s ignal, the indicator light blinks. When
you use the emergency flasher, both indicator
lights flash.

@ Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead , check the
oil level in your engine at regular inter ­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication

158 Driving and en vi ro nm ent
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 especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not stop the veh icle, drive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
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 ¢ page 17 4,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much motor o il in your eng ine
r::;> page 183, Adding engine oil~-
.. Never try to p ush- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
t h e vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183.
-Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into ..,.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. 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 ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However , wear
and nox ious em issions 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 whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper 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 .
... Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.

- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld 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 sh ie lds, switches, ign it ion 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 .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
