e lement will lock the selector lever if the lever is left in N (Neutral)
for more than approximate ly 1 second, without the brake peda l
being pressed.
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N pos ition .
Interlock button
The lock button on t he se lector lever prevents the lever from being
accidentally shifted into certain positions. Pressing this button
deactivates the selector lever lock. Depending on the direction of
the shift, the selector lever locks at different positions . The positions

il lustration => page 165, fig. 185.
Igniti on k ey sa fe ty in te rlock
The key cannot be removed from the ignition un less the selector
lever is in the
P park position. When the ignition key is removed, the
selector leve r wil l be locked in the
P posi tion .•
Kick-down
T he kick-down feature allows the vehicle to generate
maximum acceleration.
When you press t he accelerator peda l beyond the resistance point
that is reached at ful l throttle, the transmission will select a lower
gear ratio based on vehic le speed and engine RPM. The engine RP M
wi ll be control led to produce maximum vehicle acce leration as long as you continue to press the accelerator pedal beyond this resis

Dynamic shift program (DSP)
T he aut omatic transmission is electronically controlled.
T he transmission is self adapting and wi ll autom ati ca lly select the
best shift program suited to t he driving condi tions and drivi ng s tyle.
The transmission will se lect one of the
eco nom y programs when
you drive at a steady speed or a gradual ly changing speed without
heavy acce leration . T his achieves optimum fuel efficiency, with ear ly
upshifting and delayed downshifting .
T he trans mission wil l automat ica lly select the
s porty shift programs
when you drive at higher speeds, or with heavy acce leration and
frequen tly changing speeds . Upshifts are de layed to make full use
of engine power. Down shifting takes place at higher engine speeds
t han in the economy programs .
The selection of the most suitab le shift program is a continuous,
automatic process . The driver can also make the transmission
switch to a sporty program by
quickl y pressing down the gas peda l.
T his causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g . for quickly passing ano ther veh ic le .
You do not need to press the gas pedal into the kick-down range .
After the transmission has upshifted, t he original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to select the proper gear for uph ill and downh ill gradients.
T his prevents the transmission from upshifting and downshifting
unnecessa rily on hi lls. The transmiss ion will shift down to a lower

To upshift
Push the selector lever forward to the plu s position 0
~ fig. 186.
To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears
1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you apply a light thrott le when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear.
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic® wi ll downshift from the selected gear into
the next lower gear until it reaches 1st gear, based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the throttle again.
[ i ] Tips
• When you shift into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission will shift down
to a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic® is inoperative when the transmission is in the fai l-safe
mode .•

Chassis Controls
Four different driving modes can be set by the driver.
The automatic control processes are speed -and time -dependent.
For example, it is not possible to raise the suspension to the lift
mode above certain speeds .
When a speed of about 75 mph (120 km/h) is exceeded for more than 30 seconds, the vehicle is automatically lowered approximate ly 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road holding is optim ized as a result of the lower
center of gravity and fuel consumption is reduced as a result of
reduced wind resistance .

General information
The HomeLink® feature can learn up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink® transmitter before you can
use the
system=> page 191, "Programming the Homelink® trans­
mitter".
In order to program the Homelink® transmitter 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" button 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.
& WARNING
• Never use the Homelink"" transmitter with any garage door
opener that does have not the safety stop and reverse feature as
required by federal safety standards. This includes any garage
door opener model manufactured before April 1, 1982.
• A garage door opener which cannot detect an object, signaling
the door to stop and reverse does not meet current federal safety standards . Using a garage door opener without these features
increases risk of serious injury or death.
Controls and equip­ ment
& WARNING (continued)
• 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
programmed. If the device is repeatedly activated, this can over­
strain motor and damage its electrical components -an over­
heated motor is a fire hazard!
• To avoid possible injuries or property damage, please always
make absolutely certain that no persons or objects are located in
the range of motion of any equipment being operated. •

Why safety belts?
Frontal collisions and the law of physics
Frontal cras hes cre ate very strong forces for people ridi ng

The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers call this energy "kinetic energy ."
T he higher the speed of the vehicle and the greater the vehic le's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most signi fican t factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!

Safety belts protect
People think it's possible to use the hands to brace the
body in a min or c ollision . It's simply not true!

Safety belts used properly can make a big difference. Sa fety belts
help to keep passengers in their seats, gradually reduce energy
levels app lied to the body in an accident, and help prevent the
uncontrolled movement that can cause serious injuries. In addition,
safety be lts re duce the danger of being thrown out of the vehic le .
Safety belts attach passengers to the car and give them the benefit
of being s lowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other sa fety features engineered
into today's vehicles. By "absorbing" the kinetic energy over a
longer pe riod of time, the sa fety belts make the forces on the body
more "tolerable" and less likely to cause injury .
Altho ugh these examples are based on a frontal co llision, safety
belts can a lso substantially reduce the risk of injury in other kinds
of crashes . So, whether you're on a long trip or just going to the
corner store, a lways buckle up and make sure others do, too. Acci­
dent statistics show that vehicle occupants properly wearing safety
belts have a lower ris k of being injured and a much better chance of
surviving an accident. Properly using safety belts also greatly
increases the abi lity of the supplementa l airbags to do their job in a
collision . For th is reason, wearing a safety belt is legally required in
most countries including much of the United States and Canada. Although your Audi is equipped with airbags, you sti
ll have to wear
t he safety belts provided . Fron t air bags, for example, are activated
only in some frontal collisions. The front a irbags are not activated in
a ll fro ntal co llisions, in side and rear coll isions, in ro ll ove rs or in
cases where there is not enough dece leration through impact to the
front of the vehicle . The sa me goes for the other airbag systems in
you r Aud i. So, always wear your safety belt and make sure every ­
body in your vehic le is properly restrained! •
Important safety instructions about safety
belts
Safety belts must always be correctly posi tio ned across
t he strongest bones of your body.
- Al ways wear safety belts as illust rated and described in
th is chapte r.
-Make s ure tha t yo ur sa fety be lts ar e always ready for us e
and are not damage d.
& WARNING
Not wearing safety belts or w earing them improperl y increas es
the risk of serious per sonal injury and death . S afety belts ca n work
onl y when used corre ctl y.
• Alway s fa sten your s afety belt s correctly before driving off and
make sure all p assengers ar e correctly restrain ed.
• For ma ximum protect ion , safet y belts must always be po si­
tioned properly on the body .
• Never strap more than one person , including sm all ch ildren ,
into any belt.
• Never pla ce a safety belt ove r a child sitting on your lap .
• Alway s keep feet
in the footwell in front of the seat while the
vehicle is being driven .
