Introduction
Your vehicle is equipped with a S tronic transmission, also called a
double -c lu tch system/transmission .
Power is transferred between the engine and the transmission by
means of two independent clutches. They replace the torque

ce nter console:
Selector lever with
release button
-Hold the release button (button in selector lever) down,
move the selector lever to t he desired position, for
example D :::>
page 115, and release the button.
- Release the brake pedal and accelerate:::>& .
Stopping temporarily
-Bring th e 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 the selector lever to
P and release the button.
Stopping on an incline
-Always hold the vehic le with the footbrake or parking
brake in orde r to prevent "rollback":::> &. Do
not try to
prevent the vehicle from rolling back by rewing the
engine while it is in gear.
Starting on a hill
- Apply the hand brake firmly .
- With the engine in gear, gradually accelerate and release
the hand brake.
The engine can on ly be started with the selector lever in P or N
~ page 107. At low ambient temperatures (14 °F /-1 O °C), it is only
possible to start the engine with the se lector lever in P.
When park ing on leve l ground, it is sufficient to place the selector
lever in P. On a steeply sloping road , you should first apply the
parking brake firmly and then place the selector lever in
P. This way,
you do not overload the paw l mechanism and it is easier to move
the selector lever out of P.
& WARNING
• Never leave your vehicle with the engine running while in gear.
If you must leave your vehicle 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 ,
S or R ) or in "tiptronic " mode , it is essential that you stop the

vehi cle w it h the footbrake . When idl ing , the tr ansmission of power
does not stop completely -the vehicle "creeps ".
• Do not ac celerate when you change the selector lever position
with the vehicle stationary and the engine running -risk of an acci ­
dent!
• Never place the selector lever
in the R or N position while the
vehicle is mov ing -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 pedal if you are going to be stopped on an incline .
If you do , the clutch will start to slip when it overhe ats cau sed by
the constant overload . This is dangero us because if the vehicle
starts to roll backward , you could cause an accident. If the clutch
should start to slip , you will feel the vehicle "jerk" and the sele ctor
lever display will start blinking.
• Before driving down a steep slope , reduce your speed and shift
into a lower gear with "tiptronic ".
• Do not ride the brakes or apply the brake pedal too often or too
long. Constant braking causes the brakes to overheat and
substantially reduces braking performance , increases braking
di stance or cau ses complete failure of the brake system. •

N -Neutral
The transmission is in neutral in this position.
D -Normal position for driving forward
In this position, the forward gears are automatically shifted up and
down, depending on engine load and vehicle speed.
To engage S from N, the brake pedal must be depressed at speeds
below 5 km/h or when the vehicle is stationary=>&.
In certain circumstances (driving in the mountains for example) it
can be beneficial to switch temporarily to the manual shift program
=> page 118 in order to adjust the gear ratios to driving conditions
manually.
S -Sport setting
The S setting should be selected for sporting driving. The power
reserves of the engine can be fully exploited through later upshifts .
To engage S from N, the brake pedal must be depressed at speeds
below 5 km/h or when the vehicle is stationary=>&,.
& WARNING
• Never place the selector lever in the R or P position while the
vehicle is moving -risk of an accident!
• With the engine running, it is necessary to hold the vehicle with
the foot brake in all selector lever positions (except P and N), because even at idle speed the transfer of power is never
completely interrupted -the vehicle "creeps". If the vehicle is
stationary and the transmission is engaged, the engine should
never be speeded up unintentionally (e.g. manually 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 engine, the selector lever must be moved to P and the
& WARNING (continued)
parking brake applied firmly -risk of an accident! Follow the
warning stickers=>
page 212, "Engine compartment".
[ i] Tips
If you have inadvertently shifting into N while the vehicle is moving,
you should remove your foot from the accelerator and wait until the
engine speed has dropped to idle before shifting back to Dor S. •

T he selector lever lock is effective only when the vehicle is
stationary and at speeds below 5 km/h . At higher speeds, the lock in
the N position is automatically switched off .
The selecto r lever is not locked when rapid shifts are made through
the N position (e.g . from R to Dl. This allows you to "rock" the vehicle
if it becomes stuck. If the lever is in the N position for more than
1 second with the brake pedal not depressed, the selector lock
engages automatica lly.

open throttle position or Kickdown. The engine speed
settles at about 3,200 rpm (6-cylinder engine) or about
2,600 rpm (4-cylinder engine).
- Take your left foot off the brake.
The S tronic® in your vehicle is electronically controlled. A special
Launch Control Program provides the best acceleration from a
standing start .
& WARNING
• Always adapt your driving to the traffic flow.
• Only use Launch Control when road and traffic conditions allow
it and other drivers will not be endangered or annoyed by your
driving and the acceleration of the vehicle.
• Make sure that ESP remains enabled. With the ESP disabled,
the vehicle could brake away, particularly on a slick and slippery
road -risk of skidding!
• Once acceleration is finished, switch ASR on again by briefly
pushing the ESP button. •

Back -up program
In the event of a sys tem malfunction, there is an back-up
program .
In the event of system malfunctions, the automatic transmission
switches to the fai l-safe mode . This is signa lled by one segment or
al l the segments in the display illuminating or going out.
The effect of a system ma lfunction can be one of the fo llowing :
• The program shifts only into certain gears.
• Reverse gear can no longer be engaged .
• The manua l shift program (tiptronicl is switched off in the fail­
safe mode.
If the transmission switches to fail-safe mode, you should take the
vehicle to an authorized Audi dea lership as soon as possible to have
the condition corrected .•

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 121, "Programming the Homelink® trans­
mitter" .
In order to program the Homelink® transmitte r for devices utili zing
rolling cod e, 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 .
Con tro ls and eq uip­
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!
