- 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 burn yourself . Let the engine
cool off first until you can no longer see
or hear steam or coo lant escaping.
Q) Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo ile r has been designed to
proper ly distribute the cooling air wh en
t h e veh icle i s moving.
If the spoiler is
damaged, this cou ld red uce the cooling
effect and the engine co uld then over ­
heat . Ask yo ur authorized Audi dea ler fo r
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1 ,500, you should
downshift to the next lower gea r. T he red area
at the end of the sca le indicates maximum
pe rmissib le engine RPM after the break- in pe­
riod. Before reach ing this area, move these­
lector lever to position 0/5 (Drive) or ease
your foot off the accelerator peda l.
(D Note
The tachometer needle should only br iefly
be in the red zone: you cou ld damage your
eng ine! The beginn ing of the red zone var­
ies depending on the operati ng tempera­
ture of the eng ine .
@ For the sake of the environment
Upshift ing early saves fuel and reduces en­
gine noise.
@ Tips
The engine speed is limited when the en­
g ine is co ld - the full engine output is not ava
ilable . When the engine is at operating
temperature, the red area in the tachome­
ter moves to a higher RPM range.
Fuel gauge
The fuel gauge only works when the ignition is
on. If the fue l level drops below 2 .6 gallons
(10 lite rs), the bottom LED turns red and the
indicato r light
(j) turns on ¢ page 20. The
bottom L ED blinks red whe n the fuel level is
very low.
The possible range based on the current fuel level is shown in tab@¢
page 22, fig. 4.
(D Note
Neve r run the ta nk completely dry. A n ir­
r egular supply of f uel can cause engine
misfiring and fuel could enter the exha ust
system. The catalytic co nve rter could t hen
ove rheat and be damaged .

If this warning/indicator light illuminates
while you are driving, then there is a mal­
function in the engine electronics. Have the malfunction corrected as soon as pos­
sible by your authorized Audi dealer or
qualified repair facility .
o Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) is part
of the On-Board Diagnostic (OBD II) system.
The symbol
¢..j lights up when the ignition is
switched on and will turn off after the engine
has started and has settled at a constant idle
speed. This indicates that the MIL is working
properly.
The warning light illuminates when there is a
malfunction in the engine electronic system.
Contact your authorized Audi dealer and have
the malfunction corrected .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢ page 208.
For more information ¢ page 29.
!?) Engine speed limitation
II! Engine speed maximum XXXX RPM
The engine speed is automatically limited to
the speed displayed in the driver information
system. This protects the engine from over­
heating.
The engine speed limitation deactivates once
the engine is no longer in the critical tempera­
ture range and you have released the accelera­
tor pedal once.
If the engine speed limitation was activated
by an engine control malfunction, the indica­
tor light
Ga also turns on. Make sure that the
speed does not go above the speed displayed .
Drive to your authorized Audi dealer immedi­
ately to have the malfunction corrected.
'
(!) Tips
The engine speed is limited when the en­
gine is cold -the full engine output is not
available. When the engine is at operating
temperature, the red area in the tachome­
ter moves to a higher RPM range .
~~, Engine oil sensor
• Oil level! Sensor defective
If the symbol illuminates, contact your au­
thorized Audi dealer and have the oil sensor inspected . Until you have this done, check the

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.
T his is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
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 h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving 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.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­ ing through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h 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 sa lt water because
-
~ it can ca use corrosion. ,....,

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv­
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini­
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity on ce
they have warmed up.
The cooli ng fan can cont inue to run in your ve­
hicle after the engine is switched off . Howev­
er, driving the veh icle to coo l it down is pa rti c­
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
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 206,
Fuel supply .
"' Never run the tank down all the way to emp­
ty.
"' Never put too much mo to r o il in yo ur eng ine

Engine 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
cooling of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a certa in amount of oil. Oil consumpt
ion varies from
engine to engine and may change significant ly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
<=> page 196) consume more oil during the
break -in pe riod than they consume after o il
co nsump tion has stabilized.
Under normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscos ity
of the oil, the RPM (revolut ions per minute) at
wh ich the engine is operated, t he ambie nt
temperature and road conditions . Fur ther fac­
tors a re the amount of oil dilut ion from wa ter
condensation or f ue l resid ue and the oxid a­
t ion level of the o il. As any engine is subjec t to
wear as m ileage builds up, t he oil consump­
tion may increase over time until replacement of wo rn components may become necessary.
W it h a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alte rnative
to regu lar and frequent check ing of the o il lev­
el, see
Note .
If

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
qu ires 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 specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros ion addi­
tives (50% for USA models; 60% for Canadian models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil ­
ing point of the coolant.
Do not reduce the concentration of the coo l­
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 antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 ° F ( - 40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~.&.
in Working in the engine
compartment on page 211.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checkin g and fillin g 217
your vehicle is sufficient to meet the cli ­
mate conditions. This is especia lly impor­
tant if you live in a region where the win­
ter is extremely co ld. If necessary, in­
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 (check the label)
for your vehicle . This coolant additive is
avai lable at authorized Audi dealers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The resulting corrosion can cause a loss of
coolant and serious 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 Veh icle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
