Homelink®
Universal remote
control
General information
The Homelink universal remote control can
be programmed with hand-held transmitters
from existing equipment.
You must first program the Homelink ® trans­
mitter before you can use the system
~ page 90, Programming the Homelink ®
transmitter.
I n o rder to prog ram the Homelink ® transmit­
ter for devices utilizing rolling code, a second pe rson on a ladder who can safely reach the
garage doo r 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 federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signa ling 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 stand ing 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 e
lectrical components -an
overheated motor is a fire hazard!
- To avoid possib le 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.

98 Driving Safely
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
Make sure that all pedals move freely without
interference and that nothing prevents them
from returning to their original positions .
Only use floor mats that leave the peda l area
free and can be secured with floor mat fasten­
ers.
If a brake circuit fails, increased brake peda l
travel is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move freely can cause
loss of vehicle control and increase the r isk
of serious injury.
- Never place any objects in the driver 's
footwell. An object could get into the
peda l area and interfere w ith pedal func­
tion. In case of sudden braking or an ac­
cident, you would not be ab le to bra ke or
accelerate!
- Always make su re that nothing can fall
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely
attached to the floor mat fasteners and do
not interfere with the free movement of the
pedals.
... Make su re that the floor mats are properly
secured and cannot move and interfere with
the pedals~ .&_.
Use only floor mats that leave the pedal a rea
unobstructed and that are firmly secured so
that they cannot s lip out of position. You can
obtain suitable floor mats from your author­
ized Audi Dealer.
Floor mat fasteners are installed in your Audi . Floor mats used in your vehicle must be at
­
tached to these fasteners . Properly securing
the floor mats will prevent them from sliding
into positions that could interfere with the
pedals or impair safe operat ion of your vehicle
in other ways.
A WARNING ,-
Pedals that cannot move freely can result
i n a loss of vehicle control and increase the
r isk of ser ious persona l injury.
- Always make sure that floor mats are
p roperly secured.
- Never place or install floor mats or other
f loor coverings in the vehicle that cannot
be prope rly secured in place to prevent
them from slipping and interfer ing wi th
the peda ls or the ability to contro l the
vehicle.
- Never pla ce or install floor mats or other
floor coverings on top of already instal ­
led floor mats . Additiona l floor mats and
other coverings will reduce the size of
the pedal area and interfere with the
pedals.
- Always properly reinsta ll and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot
fall into the dr iver footwell while the ve­
hicle is moving . Objects can become
trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control.
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­ erly stowed and secured in the luggage com­
partment.
Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling
characteristics. Loose items can a lso increase
the risk of serious persona l injury in a sudden
vehicle maneuver or in a co llision.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various v ehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
sa fety belt s.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir purposes.
T he recording capacity of the electronic con­
trol modules is limited to data (no sound is re ­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith special equip­
ment .
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of ve hicle control. It works
only when the eng ine is running . ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course . T he in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface . When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to road , traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a ve hicle
on the road if road departure is a result of
driver inattent ion . Instead, ESC imp roves the
poss ib ility of keep ing the veh icle under con­
t rol and on the road during extreme maneu­
vers by using the d river 's steering inputs to
help keep the vehicle go ing in t he i nte nded di­
rection . If you are t raveling at a speed tha t
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/o r works togethe r with the
anti- lock b rake system (ABS), brake assist sys-
tem and anti-slip reg ulation (ASR). ESC is .,..

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 145
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- 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 al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢

Braking
General information
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their full braking
effect, they have to be "broken in" first. The
distance can be ten times longer in vehicles
with ceramic brakes*. You can compensate for
th is slightly reduced braking power by push­
ing harder on the brake pedal. Avoid heavy
braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat ­
ing condit ions and driving habits ¢.&, . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un ­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter­
vals.
Moisture o r road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads . A
few cautious brake applications should dry
off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield wipers on, the brake pads will briefly touch the brake discs in regular inter ­
vals so as to improve reaction time when brak­
i ng on wet surfaces. You, the driver, will not
notice anything. .,.

The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt -covered
road and the brakes are not used. Likewise,
you clean
off accumulated salt coating from
brake discs and pads with a few ca utious ap­
plications of the brake<=>,& .
Co rrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firmly a few times from a moderately high
speed<=> ,&.
Fa ult s in th e bra ke s yste m
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed. Drive immed iately to
the nearest qualified workshop to have the
damage repa ired. Drive at reduced speed on
the way there and anticipate longer stopping
d istances and higher peda l pressure¢ _&.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake flu id level is too low . The brake fluid
l eve l is monito red electronically .
Brake po wer ass ist un it
The brake power assist un it increases the
pressure that you generate with the brake
pedal. It works only when the eng ine is run­
ning.
Br ake lining w ear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection

_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by resting 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 operat ing
conditions such as passing through wa­
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
discs and drum s. Carefully app ly bra ke s
for a test. Brakes w ill dry and ice coa t­
ings w ill be cleaned
off after a few care­
fu l brake applications.
- Driving for an extended period of time on
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few cautious
brake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in­
creased stopping distance. Avoid driving
the vehicle a nd have it towed to the near­
est A udi dealer or qualified workshop .
- Never let the veh icle roll to a s top with
the engine shut
off. .,.

tract the rear spoiler complete ly. You cannot
retract the rear spoiler if it extended due to
the engine compartment temperature .
Indicator light
When the indicato r light (.-) appears, there is
a system malfunction . The rear spoiler may
not be able to extend . This cou ld change the
vehicle's driving characteristics at high
speeds. Do not exceed 87 mph (140 km/h) .
Drive to your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
Driving at higher speeds without the rear
spoiler deployed can impair handling char­
acteristics, making the vehicle ha rder to
control.
- Imp roper operation of the rear spoiler
can cause crushing injuries. Always ma ke
sure that nobody, especia lly children, is
in the way when the rear spoi ler is de­
p loyed or retracted.
- Always obey speed limits and other traf­
fic laws .
- Ho t air from the eng ine compartment
can escape thro ugh the rear spoiler when
it is open and it could burn you.
(D Note
- Never push the vehicle or apply force to
t he rear spoiler -it could be damaged.
- Operate the rear spoiler manually only
when the eng ine compartment lid is
closed, otherwise there is a risk of dam­
age .
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compa rtment must
always be free of ice, snow, leaves or other
debris.
