The selection of the most suitable shift program is a continuous,
automatic process. The driver can also make the transmission
switch to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g. for quickly passing another vehicle.
You do not need to press the gas pedal into the kick -down range.
After the transmission has upshifted, the original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients .
This keeps the transmission from shifting up and down unneces ­
sarily on hills. The transmission will shift down to a lower gear when
the driver presses the brake pedal on a downhill gradient. This
makes use of the braking effect of the engine without the need to
shift down manually .•

If you apply a light throttle 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 a ccelerator peda l when driving down a
steep incline, 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 . .,_

& WARNING (continued )
-When the selector lever is in a driving position , the vehi cle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move ,
because power is transmitted to the wheels as soon as a
driving position is engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission.
- Remember : - even when stopped briefly with the automatic
transmission in "D", "S" or "R" , engine power is being trans ­
mitted to the wheels . Your vehicle could "creep " forward or
backward . When stopped , keep the brake pedal fully depressed
and use the parking brake if necessary to keep the vehicle from
rolling .
- If the sele ctor lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving
position .
- Never shift into "R " or "P " when the vehicle is in motion .
- Never get out of the driver's seat when the engine is running.
- If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly .
- If the engine must remain running, never have any driving
position engaged when checking under the hood. Make sure
the selector lever has securely engaged and is locked in "P "
with the parking brake firmly set :::::, page 289, "Engine
compartment ". Otherwise , any increase in engine speed may
set the vehicle in motion , even with the parking brake
applied .•

The transmission se lects the appropriate gear ratio (upshifts and
downsh ifts) automatical ly based on preset driving programs.
The transmission wil l select one of the
economy programs when
yo u drive at a steady speed or a gra dually changing speeds without
heavy acceleration . T his gives best fuel efficiency, with early
upshifting and delayed downshif ting .
The transmission will au tomat ically select the
s porty shift programs
when you drive at higher speeds, or with heavy acce leration and
freque ntly changing speeds . Upshifts are delayed to make full use
of engine power. Downshifting takes place at higher engine speeds
t han in t he economy programs .
The se lection of the most suitable shift program is a continuous,
automatic process . The driver can also make the transmission
sw itch to a spor ty progra m by
quickly pressing down the gas peda l.
This causes the transmission to shift down into a lower gear ratio and makes qu ick acceleration possible (to pass another vehic le) You
do not need to press the gas peda l into the kickdown range . After
the trans missi on has upshifte d, the o riginal p rogram is selected

An additional shift program allows the automat ic t ransmission to
select the p roper gear for uphill and downhill gradients.
This prevents the transmission from shifting up and down unneces­ sari ly on hills. The transmission will shift down to a lower gear ratio
when the driver presses the brake pedal on a downhill gradient . This
makes use of the braking effect of the engine without the need to
shift down manually.
If you are driving in hills and mountains, the transmission will
continuously adjust the gear ratio to the road grade. If you press the
brake pedal when driving downhi ll, the transmission will down shift
automatically . This increases the braking effect of the engine .
If the cru ise control is on when you are traveling downh ill, the trans ­
mission will automatically select a lower gear ratio in order to main ­
tain the set vehic le speed . This wil l cause the engine speed to
increase. •

Universal remote control
Applies to vehicles: w ith Home Link® universal remote control
General information
The Homelink® feature can learn the 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 186, "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 .
& 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. •

occupants and especially for children. Therefore:
Never allow anyone to assume an incorrect seating posi ­
tion when the vehicle is being used=>& .
The following bulletins list only some sample positions that will
increase the risk of serious injury and death. Our hope is that these
examples will make you more aware of seating positions that are
dangerous.
Therefore, whenever the vehicle is moving:
• never stand up in the vehicle
• never stand on the seats
• never kneel on the seats
• never ride with the seatback reclined
• never lie down on the rear seat
• never lean up against the instrument panel
• never sit on the edge of the seat
• never sit sideways
• never lean out the window
• never put your feet out the window
• never put your feet on the instrument panel
• never rest your feet on the seat cushion or back of the seat
• never ride in the footwell
• never ride in the cargo area
& WARNING
Improper seating positions increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants stay in a proper
seating position and are properly restrained whenever the vehicle
is being used. •
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 pedal area free and can be
secured with floor mat fasteners.
If a brake circuit fails, increased brake pedal travel is required to
bring the vehicle to a full stop.
& WARNING
Pedals that cannot move freely can cause loss of vehicle control
and increase the risk of serious injury.
• Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate!
• Always make sure that nothing can fall or move into the
driver's footwell. •
Floor mats on the dr iver 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 sure that the floor mats are properly secured and
cannot move and interfere with the pedals=>& . .,

________________________________________________ D_r_iv _ i _n_ g~ S_ a_ fe_ ly __ lffllll
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position. You can
obtain suitable floor mats from your authorized Audi Dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners.
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways .
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control. •
