Transmission S tronic transmission
Introduction
Your vehicle is equipped with a S tronic trans­ miss ion, also called a double-clutch system/
transmission.
Power is transferred between the engine and
the transmission by means of two i ndepend­
ent clutches. They replace the to rque convert­
e r of conventional automat ic transm iss ions
and a llow the vehicle to acce lerate without a
noticeable break in the power flow .
W ith the aid
of tiptr oni c, the gea rs can op ­
tionally be sh ifted
manually¢ page 84.
Selector lever positions
All the selector lever positions are explained
in this section.
F ig . 89 Display: Selector lever position

A WARNING
-Never p lace the selector lever i n the R or
P posit ion while the veh icle is moving -
risk of an accident!
- With the engine r unning, it is necessary
to hold the vehicle with the foot brake in
all se lector lever positions (except P and
N), because even at idle speed the trans­
fe r of power is never completely inter­
r u pted -the vehicle "creeps". If t he vehi­
cle is stat io nary and the transm ission is

Kick -down feature
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
upshift into the next higher gear takes place
as soon as the maximum specified engine
speed is reached.
_&. WARNING
Please note that the drive wheels can spin
if the kick-down is used on a smooth slip­
pery road -risk of sk idding!
Launch Control Program
The Launch Control Program permits maxi­
mum acceleration.
In order to use Launch Control, the ASR (Anti­
Slip Regulation) must be disabled. When ASR
is disabled, the ESC warning/indicator light

that Launch Control can be used, the engine must be at operating temperature and the
steering wheel must not be turned .
.. With the engine running, briefly press the
ESC button . The message "Stabilization pro­
gram off" or "Sport control Warning! Re­
stricted stability" in the driver information
system display.
.. Shift the gear lever to "S" or the tiptron ic
position .
.. Step on the brake pedal with your left foot
and keep the brake pedal fully depressed for
at least one second .
.. With your right foot, step on the accelerator
to the wide-open throttle position or Kick­
down. The engine speed settles at about
3,200 rpm.
.. Take your left foot off the brake.

86 Transmis sion
& WARNING ,-
- Always adapt your driving to the traffic
flow.
- 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 ESC remains enabled.
With the ESC disabled, the vehicle could
brake away, particularly on a slick and
slippery road - risk of skidding!
- Once acce lerat ion is finished, switch ASR
on again by briefly pushing the ESC but­
ton.
(j) Tips
- The transmission temperature may in­
crease significantly after using the Launch Control Program. If that hap­
pens, the program may not be available

- When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads . This can result in
increased wear.
Back-up program
In the event of a system malfunction, there is
a back-up program.
In the event of system malfunction, the auto­
matic transmission switches to the fail-safe
mode. Al l 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 illum inated, the clutch is
overheating and could be damaged if you con­
t inu e to drive. Stop the vehicle and allow the
transmission to cool with the se lector 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 repa ir facility immed iately to have the
malfunction corrected .

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 88 , Programming the Homelink
transmitter.
In order to program the Homelink 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 garag e door open er motor . Refer
to the ope rating instructions for the opener ,
as the location and color of this bu tton 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 required by federal 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, 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
equipment being operated.
