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 .

Automatic transmission
vehicle when the engine is running, activate
the parking brake and move the selector lev­
er to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the engine
is running and the selector lever is in D/S or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicator lamp
5] illuminates
and a driver message appears¢
page 86
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
¢page 187. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the transmission to
overheat and can damage it. Activate the
84
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle .
Hill descent control
The hill descent control system assists the driver
when driving down declines.
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitation s.
It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
level s out or you press the accelerator pedal.
On vehicles with the cruise control system*
¢
page 78, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.

A WARNING
-Always adapt you r driving to the traffic flow.
- Only use the La unch Control P rogram when
road and t raff ic conditions a llow i t and oth­
er drivers wi ll not be endangered or annoye d
by your driving and the veh icle's accelera­
t ion.
- Please note that the driving wheels can spin
and the vehicle can brea k away w hen spo rt
mode is switched on, especially when the
road is slippery.
- Once you have accelerated, yo u should
switch sport mode off
by pressing the
I ~ OF FI button.
(D Tips
- The t ransmission tempe ratu re may inc rease
significantly after using the La unch Control
Program. If that happens, the program may
not be available for a few minutes. It will be
ava ilable again after a coo l-down period .
- When accelerat ing using the Launch Contro l
program, all vehicle pa rts a re subject to
heavy loads. This can result in increased
w ear.

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .
Fig. 152 Version A : lower center console,~ OFF button
The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The
170

amount of sta bilization control will differ de­
pending on the level.

Smart Technolog y
-If y ou dama ge the front spo iler, or if you in ­
sta ll a di fferent spoile r, be sure the air flow
to the front brakes is not obstructed . Other ­
wise the brake system co uld overheat reduc­
ing the effectiveness o f the enti re brake sys­
tem .
- Failure of one brake c ircuit will impair the
braking capab ility r esult ing in a n increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest au thorized
Audi de aler or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
-If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

Driving with your quattro
With all-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend­
i ng on your driving style and the road conditions
at the t ime . See also ~ page 169.
A center d ifferential distributes the driving power
variably to the front and rear axle. It works to­
gether w ith select ive whee l torque control, which
activates w hen d rivi ng throug h curves

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 .
- T o assure efficient oper ation of the Emission
