the vehicle stationary as well as moving.
When accelerat ing, the transmission shifts in­
to the next gear in gears 1, 2, 3, 4 and 5
shortly before the maximum permissible en­
gine speed is reached. If
you have selected a lower gear than the cur ­
rent one, the transmission will only shift down
when the eng ine cannot be overspeeded.
If kick-down is act uated, the transmission
shifts into a lower gear independently of
speed and engine rpm.
Steering wheel with Tiptronic ® controls

S the transmission will switch back to the
automatic mode if you do not use the pad­
dles within approx. 30 seconds.

Kick-down feature
Applies to vehicles: with S tron ic
The kick-down feature allows maximum ac­
celeration .
If you depress the accelerator pedal fully be­
yond the full-throttle position, the transmis­ sion automatically downshifts one gear, de ­
pending on vehicle speed and engine rpm . The
upsh ift into the next higher gear takes place
as soon as the max imum specified engine
speed is reached.
A WARNING
Please note that the drive wheels can spin
if the kick-down is used on a smooth s lip­
pery road - risk of skidding!
Launch Control Program
Applies to vehicles: with S tron ic
The Launch Control Program permits maxi ­
mum acceleration .
In o rder to u se La unch Control, the ASR (An ti­
Slip Reg ulation) mus t be d is a b led. When ASR
is disab led, the ESC wa rning/ind icator light
IJ
in the inst rument cluster illuminates . So that
L aunch Cont ro l can be used, the engine must
be at operating temperature and the steer ing
wheel must not be turned.

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 87, 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 ope rating inst ructions for the opener ,
as the location and color of this bu tton may
vary by manufacturer .
You can still use the origina l remote control
fo r 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 model man ufactured 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-
Homelin k® 87
tivated, this can overstrain motor and
damage its e lectrical components -an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make abso lutely
certain that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

122 Airbag system
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­ lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop. -
Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty & Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

132 Child Saf ety
seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re­
straints and for the d ifferent models of the
same kind of child restraint offered by child
restra int manufacturers.
The weight ranges for the individual types,
makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced A ir­
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi ­
cal 1 yea r-old ch ild, the Advanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the in formation stor­
ed in the electronic control unit.
The ele ctron ic cont rol unit also registers the
tension on the front passenge r safety belt.
The tension on the safety be lt fo r the front
passenger seat will be different for an ad ult
who is properly using the safety belt as com­
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measu res the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whe ther there is a ch ild restraint w ith a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards a nd has been certified by its manu­
facture r fo r u se w ith an airbag. Always be s ure
that t he ch ild res traint is p rope rly insta lled at
one o f th e rear seat ing pos itions. If in excep­
tional c ircu mstances you must use it on the
front passenger seat, caref ully read all of the
info rmation on c hild safety and Advanced Air­
bags and heed all of the applicable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weig ht-sensing mat
inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag stat us is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light.
Many types and models of child res traints
have been available over the years, new mod­
els are introduced regu larly incorporating new
and improved des igns and older models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and diff erent 'footpr ints,' the s ize and shape
of the bo ttom of the ch ild restra int that sits
o n t he seat, when they a re inst alled on a vehi­
cle sea t. Th ese d ifferences make it vir tually
impossible to certify compliance with the re ­
quirements for advanced airbags with eac h
and every child restra int that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For th is reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of specific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System i n your veh icle w ith the suppression
requirements of Federal Motor Vehicle Safety
Standa rd 208. These chi ld restraints are:

- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­

@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maxi -
mum speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
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 sea led and generally re­
qu ires little at tention.
The cooling system has been filled at the fac ­
tory with a permanent coolant which does not n eed to be changed. The coolant consists of a
mixture of wa ter and the man ufacturer's g ly ­
col-based coolan t addi tive Gl3 ant ifree ze
with ant icorrosion add itives (50% for USA
models; 60% for Canadian models) . This mix­
ture both assures the necessary frost protec ­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling po int of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
lea st 50°/4 but not more than 60°/4
to ma in­
tain antifreeze protection and cooling efficien­ cy. If the coolant frost pro tect io n is too low,
