~ Push the lever Q fig. 80 -Arrow- ¢&_ .
~ Move the steer ing whee l to the desired posi ­
tion.
~ Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detai led informat ion on how to adjust the
driver's seat, see
Q page 61.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 92, fig . 99. If
you can not maintain this min imum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing wheel is aligned with your
face, the supplemental dr iver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steer ing whee l is aligned with your
chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o' clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never ho ld the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub . Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

Starting and stopping
the engine
' Starting the engine
The engine can only be started with an origi­
nal Audi key .
.,. Se t the par king brake.
.,. Move the selector lever in P or
N q .&_ .
.,. Turn the ignition key to position @
~ page 72, fig. Bl -do not depress the gas
peda l when starting the engine!
.,. Let go of the key as soon as the engine
starts .
A cold engine may at first be loud after it has
been started. This is due to the hydraulic
valves bu ild ing up the oil pressure. Th is nor­
mal and no need for concern .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine co ntain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.
- Never leave the engine id ling unattend­
ed. An una ttended veh icle w ith a runn ing
engine poses a danger o f personal injury
or theft .
(D Note
-Avo id high engine speeds, fast accelera ­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
engine.
- The e ngine cannot be started by pushing
or towing the vehicle . .,..

7 4 On the road
@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
veh icle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Maintain moderate speed until the
engine is comp letely warm. Remember,
the engine performs best at operating
temperature.
Stopping the engine
• Turn the ign ition key to position@
~ page 72, fig. 81.
&_ WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the
ignition key . The radiator fan can also
turn on again if the engine coolant heats up because of intense sunlight or heat
build-up in the engine compartment.
(D Note
Do not stop the engine immediate ly after
hard or extended driving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up.

Aud i magnetic ride is an electronically con­
trolled damping system. This chassis system
assists the dr iver by adapting to the particular
situation through imperceptible control proc­
esses. The
da mping provides individua l modu­
lation of damping forces. For example, with
damping characteristics set to provide greater
comfort, damping is set somewhat harder for
a brief period only
as required, when rounding
a curve and when braking.

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

when the vehicle is stationary¢&. .
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

engag ed, the engine shou ld neve r be
spe eded up unintentionally (e.g. manual­
ly from under the hood). Otherwise the
vehicle will immediately start to move -
sometimes even if the parking brake is
firmly applied -risk of an accident!
- Before you or other persons open the
hood and work on a running eng ine, the
selector lever must be move d to P and

Starting the engine
.. The selector lever must be in the P or the N
position. At low temperatures (below -10
0 (), the engine can only be started when the
selector lever is in the P position .
Starting from stop
.. Step on and hold the brake pedal.
.. Hold the release button (button in se lector
lever) down, move the selector lever to the
desired position, for example D
c:> page 81,
and release the button .
.. Release the brake pedal and accelerate
¢,& .
Stopping temporarily
.. Bring the vehicle to a full stop with the
brake, e.g . at traffic signals .
.. Do not accelerate .
Parking
.. Step on and hold the brake pedal¢_& .
.. Apply the parking brake firmly.
.. Hold the release button down, move these­
lector lever to P and release the button.
Stopping on an incline
.. Always hold the vehicle with the footbrake
or parking brake in order to prevent "roll­
back"
¢ _& . Do not try to prevent the vehi­
cle from rolling back by rewing the engine
while it is in gear.
Transmission 83
Starting on a hill
.. Apply the hand brake firmly.
.. With the engine in gear, gradually acceler-
ate and release the hand brake.
The engine can only be
started with the selec ­
tor lever in P or N
c:> page 7 3. At low amb ient
temperatures (14
°F /-10 °C), it is only possi­
ble to start the engine with the selector lever
in P.
When parking on level ground, it is sufficient
to place the selector lever in P. On a steeply
sloping road, you should first apply the park­
ing brake firmly and then place the selector
lever in P. This way, you do not overload the
pawl mechanism and it is easier to move the
selector lever out of P .
A WARNING
- Never leave your vehicle with the engine
running while in gear . If you must leave
your veh icle with the engine running, set
the parking brake and engage the park
lock .
- When the engine is running and the
transmission is in gear (D, Sor R) or in
"t iptroni c" mode, it is essential that you
stop the vehicle with the footbrake .
When idling, the transmission of power
does not stop completely - the vehicle
"creeps".
- Do not accelerate when you change the selector lever position with the vehicle
stationary and the engine running - risk
of an accident!
- Never place the selector lever in the R or
N position while the vehicle is moving -
risk of an accident!
- If you have to bring your vehicle to a stop
while on an incline, keep the foot brake depressed all the way down so that the
vehicle does not start to roll backward .
You should never hold the vehicle using
the clutch if you are going to be stopped
on an incline. If you do, the clutch w ill
start to slip when it overheats caused by
the constant overload. This is dangerous .,.

If you have selected a lower gear than the cur­
rent one, the transmission will only shift down
when the engine cannot be overspeeded .
If kick-down is actuated, the transmission
shifts into a lower gear independent ly of
speed and engine rpm .
Steering wheel with Tiptronic controls
The selector paddles allow the driver to keep
both hands on the steering wheel when shift­
ing gears.

Shifting down
.. Pull the left paddle, marked 0 ¢ fig. 94
briefly towards you.
The selector paddles on the steering wheel
are activated when the selector lever on the
center console is in D, Sor in the manual posi­
tion (Tiptronic mode).
You can also shift gears in the Tiptronic mode
using the selector lever on the center console.
@ Tips
With the gear selector lever in either Dor
S the transmission will switch back to the
automatic mode if you do not use the pad­
dles within approx . 30 seconds.
Transmission 85
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
I) in the instrument cluster illuminates. So
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
for a few minutes.
It will be available
again after a cool-down period.
- 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.
