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

Starting from stop
.. Step on and hold the brake pedal.
.. Hold the release button (button in selector
lever) down, move the selector lever to the
desired position, for example Do
page 87,
and release the button .
.,. Release the brake pedal and accelerate
o,& .
Stopping temporarily
.. Bring the vehicle to a full stop with the
brake, e.g . at traffic signals.
.. Do not accelerate.
Parking
.. Step on and hold the brake pedal o _&.
.. Apply the parking brake firmly.
.. Hold the release button down, move these­
lector lever to P and release the button .
Stopping on an incline
.. Always hold the vehicle with the footbrake
or parking brake in order to prevent "roll­
back" o
_&. Do not try to prevent the vehi­
cle from rolling back by rewing the engine
while it is in gear.
Starting on a hill
.. Apply the hand brake firmly.
.. With the engine in gear, gradually acceler­
ate and release the hand brake.
Transmission 89
The engine can only be started with the selec­
tor lever in P or N
opage 81. At low ambient
temperatures
(14 °F /-10 °C), it is only possi­
ble to start the engine with the selector lever
in P.
When parking on level ground, it is sufficient
to place the selector lever in P. On a steeply
sloping road, you should first apply the park­
ing brake firmly and then place the selector
lever in P. This way, you do not overload the
pawl mechanism and it is easier to move the
selector lever out of P .
.&_ WARNING
-Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle with the engine running, set
the parking brake and engage the park
lock.
- When the engine is running and the
transmission is in gear (D, Sor R) or in
"tiptronic" mode, it is essential that you
stop the vehicle with the footbrake.
When idling, the transmission of power
does not stop completely -the vehicle
"c reeps" .
- Do not accelerate when you change the
selector lever position with the vehicle
stationary and the engine running - risk
of an accident!
- Never place the selector lever in the R or
N position while the vehicle is moving -
risk of an accident!
- If you have to bring your vehicle to a stop
while on an incline, keep the foot brake
depressed all the way down so that the
vehicle does not start to roll backward.
You should never hold the vehicle using
the clutch if you are going to be stopped
on an incline. If you do, the clutch will
start to slip when it overheats caused by
the constant overload . This is dangerous
because if the vehicle starts to roll back­
ward, you could cause an accident. If the
clutch should start to slip, you will feel
the vehicle "jerk" and the selector lever
display will start blinking. ..,.

92 Transmission
-Only use Launch Control when road and
traffic conditions allow it and other driv­
ers will not be endangered or annoyed by
your driving and the acceleration of the
vehicle.
- Make sure that ESP remains enabled.
With the ESP disabled, the vehicle could
brake away, particularly on a slick and
slippery road -risk of skidding!
- Once acceleration is finished, switch ASR
on again by briefly pushing the ESP but­
ton.
Back -up program
In the event of a system malfunction, there is
an back-up program .
In the event of system malfunction, the auto­
matic transmission switches to the fail-safe
mode . All of the selector lever position dis­
plays for the automatic transmission are high­
lighted with a light background in the instru­
ment cluster display . In some cases you can­
not use reverse gear any more.
If the transmission switches to fail-safe
mode, you should take the vehicle to an au­
thorized Audi dealership as soon as possible
to have the condition corrected.
Clutch is overheating
• Clutch is overheating! Please stop vehi­
cle!
If the symbols are illuminated, the clutch is
overheating and could be damaged if you con­
tinue to drive . Stop the vehicle and allow the
transmission to cool with the selector lever in
the
P position while the engine runs at idle. If
the warning does not turn off, do not continue
driving. See your authorized Audi dealer or
qualified repair facility for assistance. Other ­
wise serious transmission damage could re­
sult. Once the indicator light has turned off,
drive to your authorized Audi dealer or quali­
fied repair facility immediately to have the
malfunction corrected.
Selector lever emergency release
If the vehicle 's power supply fails, the selec­
tor lever can be released in an emergency.

Homelink ®
Universal remote
control
General information
The Homelink ® feature can learn up to three
radio frequency codes for most current trans­
mitters used for operating garage doors, es­ tate gates, home or outdoor lighting sys­
tems , and other devices.
You must first program the Homelink ® trans­
mitter before you can use the system
¢ page 95, Programming the HomeLink ®
transmitter.
In order to program the Home Link ® transmit­
ter for devices utilizing rolling code, a second person on a ladder who can safely reach the
garage door opener motor is recommended.
It is also necessary to locate the "learn" but­
ton on your garage door opener motor . Refer
to the operating instructions for the opener,
as the location and color of this button may
vary by manufacturer .
You can still use the original remote control
for the device at any time.
A WARNING -
- Never use the Homelink® transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federal safety stand­
ards. This includes any garage door open­
er mode l manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the Homelink
® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components -an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make absolutely
certain that no persons or objects are lo­
cated in the range of motion of any
equ ipment being operated.

150 Intelligent te chn olog y
Noises from the b rake system signal that
wheel spin is being controlled.
Driving off
When drivi ng off, a lways be sure to keep road
conditions in mind as you accelerate. If one
d rive wheel spi ns because it is on a surface
with less grip, gradua lly increase the press ure
on the accelerator pedal until the car starts to
move. The wheel less able to transfer power
spins.
O verheating of bra kes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads, the EDL cuts out temporarily. The vehi­
cle rema ins operationa l and behaves in the
same way as a vehicle without EDL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the acce lerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce yo ur ability
to contro l your car. -Risk of crash!
- The increased safety afforded by EDL
does not mean that you can ta ke safety
risks. Always adapt your dr iving sty le to
the road conditions and traff ic situa tion.
@ Tips
If a fa ult occurs in the ABS, the EDL is also
not f unct ion ing. This is indicated by the
ABS warning light ¢
page 17.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning wh en the car is
accelerating.
General notes
The Anti-Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
(ESP). When th e vehicle starts up and acceler- ates, the whee
ls are prevented from spinning
by adjusting the engine power to match the
amount of grip available from the road sur­
face.
How the system works
ASR pe rforms a utomat ica lly, i.e . w ithout t he
driver's intervention. With the aid of the ABS
sensors ¢
page 153, ASR monitors t he speed
of the dr iven whee ls . If the whee ls start to
spin, the engine torq ue is reduced automati­
cally until the tires find enough gr ip to lock
onto the road surface . The system is active
across the ent ire speed range .
The ASR works in conjunction with the ABS. If
a malfunction should occur in the ABS, the
ASR w ill also be out of act io n.
@ Tips
To ensure that the ASR works properly, all
four whee ls must be fitted wit h ident ica l
tires . Any differences in ro lling radius of
the tires can cause the system to reduce
engine power wh en this is not desired. See
a lso
¢ page 205, New tires and repla cing
tires and wheels.
Rear spoiler
The rear spoiler improves vehicle handling
and enhances driver control .
Fig. 131 Switc h fo r rear spo iler
The rear spoiler deploys and retracts. Spoiler
operation can be set for automat ic or manual
operation .

152 Intelligent technology
Corrosion
There may be a tendency fo r dirt to bu ild up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes .
I f the b rakes are not used frequen tly, or if cor ­
rosion has fo rmed on the discs, it is advisab le
to clean
off the pads and discs by b raking
firm ly a few times from a moderate ly high
speed
c> .& .
Fault s in the bra ke sy ste m
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circu its may have failed¢.& .
Low brake fluid level
Malf unc tions can occur in the brake system if
the brake fl uid level is too low. The b rake fluid
l eve l is monitored electronica lly .
Brake lining wear status
Brake lin ing wea r may be c hecked by visual i n­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection ¢
page 222, What should I be
aware of when changing a tire?.
Brake power assist unit
The brake power assist un it increases the
p ress ure th at yo u genera te with the b rake
pedal. It works on ly when the engine is run­
ning.
& WARNING
- Yo u should perform braking maneuve rs
for the purpose of clean ing the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss io n into a lowe r
gear or lowe r driving position . Do not
ride the brak es or ho ld the pedal down
too long or too ofte n. This cou ld cause the brakes to get hot and dimin
ish b rak­
ing efficiency.
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing through wa­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the
b rakes can be reduced . In wi nte r, ice can
a ccumu late on the br ake pads , lin ings,
d iscs and drums. Cautiously app ly bra kes
for a test . Brakes wi ll dry and ice coat ­
ings wi ll be cleaned
off after a few cau­
tious b rake app lications .
- Driving for an exten ded period of t ime on
salt-covered roads without using your
brakes can a lso affect bra king efficiency.
Clean
off accum ulated salt coating from
brake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you
install a diffe rent spoiler, be sure the a ir
f low to the front b rakes is not obs truc t­
ed. Otherwise the bra ke system could
overhea t redu cing t he effectiveness o f
the entire brake system.
- Fai lure of one b rake circuit will impa ir
the braking capa bility result ing in an in­
cre ase d stopping dist ance. Avoid driving
the vehicle and have it towed to the near ­
est A udi dealer or qualified workshop .
- Never let the vehi cle roll to a s top with
the engine sh ut
off .
- If t he bra ke booste r is no t working, for
examp le when towing yo ur vehicle, or
because the brake booster has somehow
been damaged, the bra ke peda l must be
pressed considerably harder to make up
for the lack of booster assistance .
