A WARNING
-Always observe the warning in¢ page 187,
before open ing the hood and check ing 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
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .

(140 km/ h) if the spoiler is not deployed.
Have the spo iler inspected as soon as possi­
ble by an author ized Audi dealer or qualif ied
workshop.
- Always obey speed limi ts and o ther traffic
laws .
A WARNING ,.__.__
Improper ope ration of the rear spoiler can
cause crushing injuries .
- Always make sure that nobody, espec ia lly
children, is in the way when the rear spo iler
is deployed or retracted .

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking e ffect, they
have to be "broken in" first¢.&. . The break -in pe ­
riod can be considerably longe r for vehicles with
ceramic brake rotors*. You can compensate for
th is slightly reduced braking power by pushing
harder on the brake pedal. Avoid heavy braking
loads during the b reak-in period.
Op era ting condition s and dri ving h abit s
The brakes on today's automobiles are still sub­
j ect to wear, depending largely on operating con­
dit ions and driving habits ¢.&, . On vehicles that
are either dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by yo ur autho rized Aud i dealer more of­
ten than specified in the
Warranty & Mainte·
nan ce bookl et.
Fail ure to have you r brake pads
i nspected c an resu lt in red uced b rake pe rform ­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine. This way, you prevent unnec ­
essary wear on the bra ke system. If yo u must use
you r brakes, do not hold the brakes down contin ­
u ously. Pump the brakes at intervals .
Operating noise
Noises may occur when brakin g depending on the
speed, braking force and ou ts ide cond itions su ch
as tempera ture and hum idity.
Due to the nature of the materials used in ceram­
i c bra ke roto rs*, noises may become mo re appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water, in heavy rain, after overnight con­
densation or after washing your car , the braking
effect can be redu ced by moistu re or ice on the

Driving and th e environment
(D Tips
-Check the depth of the water before driving
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 vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Warming up and cooling down
By carefully warming up and cooling down your
veh icle, you can help ensure that it is not over­
stressed unnecessar ily du ring sporty dr iv ing.
When warming up, the vehicle is driven at a max­ imum engine speed of 6000 RPM in order to ra ise
the engine oil temperature to a m inimum of
140 °F (60 °C). T he tires also only reach their full
road holding capab ility once they have wa rmed
up.
The cooling fan can continue to run in your vehi­
cle after the eng ine is switched
off. However,
d riving the vehicle to cool it dow n is part icu larly
important. During sporty d riving, the engine and
brakes , the exhaust system, and the transmission
all become extremely hot. Before you park the
vehicle, you should drive it for a few mi les/kilo ­
meters at light load in the low rpm range to al­
low it to cool down.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in on
environmentally sound manner .
.. Always use lead -free gasoline c::> page 183,
Fuel supply.
.. Never ru n the tank down a ll the way to empty.
.. Neve r pu t too m uch motor oil in your engine
c::> page 191, 't:::?: Adding engine oil .
178
.. Never try to push -or tow-start your vehicle .
The catalytic converte r is an effi cient "clean-up"
device b uilt into the exha ust system of the veh i­
cle. The cata lytic conve rter burns many o f the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
The exclusive use of unleaded fue l is c ritically im ­
po rtant for the life of the catalytic conver ter and
proper functioning of the engine .
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. Th is could resu lt in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust 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 rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iving, the substance
used for unde rcoat ing could overheat and
cau se a fire.
@ Note
- Be aware that just one tank fill ing with lead­
ed
fuel w ill al ready ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
c::>poge 191.
-Do not drive until the fue l tank becomes
completely empty . T he engine cou ld m isfire .
Unburned fu el could also get into the ex­
haus t sys tem a nd this could cause the cata­
lyt ic converte r to overheat.
- Do not turn
off the ignition while the vehicle
is
moving.
- Do not continue to operate your veh icle un­
der these condi tions, as otherwise f uel can
re ach the cat aly tic converter. This could re ­
s u lt in ove rheat ing of the c onve rter, requ ir­
ing its replacement .

A WARNING
A hood that is not comp letely latched could
fly up and block your view while driving.
- When you close the engine hood, check it to
make sure the safety catch has properly en­

surrounding vehicle body parts.
- If you notice while driv ing that the hood is
not secured properly, stop at once and close
it.
Working in the engine compartment
Be especially careful whenever you work in the
engine compartment.
