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

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. •

The se lector lever is locked in the P and N positions when the igni ­

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.

The release button in the selector lever handle prevents accidenta l

T he kick-down feature allows maximum acceleration.
If you depress the accelerator pedal ful ly beyond the ful l- th rott le

depending on vehicle speed a nd engine rpm . The upshi ft into the
next higher gear takes place as soon as the maximum specified
engine speed is reached.

Launch Control Program
The Launch Control Program permits maximum accelera­
tion.
In order to use Launc h Control, t he ASR (Anti-Slip Regula­
tion) must be disab led. When ASR is disabled, the ESP
warning/indicator light
f in t he instrument cluster illumi ­
nates . So that Launch Control can be used, the engine must
be at operat ing temperature and the steering wheel must
not be turned.
- With the engine running, briefly press the ES P button.
The message "ASR off" appears in the instrument cluster
display .
- Shift the gear lever to "S" or the tiptronic® position.
- Step on the brake peda l w ith yo ur left foo t an d keep the
brake peda l fully depressed for at least one second. ._

- With your right foot, step on the accelerator to the wide­
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. •

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!
• 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. •

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety risks for everybody in the vehicle increase and you also
Controls and equip­ ment Safety first Vehicle operation
become a
hazard to everyone else on the road =>&, .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc .).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.

Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the
driver's seat to the following position:
- Adjust the driver's seat so that you can easily push the
pedals all the way to the floor while keeping your knee(s)
slightly bent=:>& . - Adjust the angle of the seatback so that it is in an upright
position so that your back comes in full contact with it
when you drive.
- Adjust the steering wheel so that there is a distance of at
least 10 inches (25 cm) between the steering wheel and
your breast bone=:> fig. 118. If not possible, see your
authorized Audi dealership about adaptive equipment.
- Adjust the steering wheel so that the steering wheel and
airbag cover points at your chest and not at your face.
- Grasp the top of the steering wheel with your elbow(s)
slightly bent.
- Adjust the head restraint so that the upper edge is as even with the top of your head as possible but no lower
than eye level and so that it is as close to the back of your
head as possible =:> fig . 119 .
- Fasten and wear safety belts correctly=:>
page 141.
- Always keep both feet in the footwell so that you are in
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
=> page 89 .
& WARNING
Drivers who are unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it deploys. To help reduce
the risk of serious personal injury:
• Always adjust the driver's seat and the steering wheel so that
there are at least 10 inches
125 cm) between your breastbone and
the steering wheel. ..
