there will be no acoustic warning at the next attempt to activate the system. Have the problem corrected.
There is no confirmation tone when reverse gea r is engaged if there
is a system malfunction .
For the parking assist to operate, the sensors must be kept clean
and free of ice.

Audi magnetic ride is an e lectronically controlled damping system.
This chassis system assists the driver by adap ting to the particular
situation through imperceptib le control processes. The
damping
provides individua l modulation of damp ing 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 .

Select the standard setting if you prefer a suspension setting
emphasizing comfort .

Selector lever positions
All the selector lever positions are explained in this
section.
Fig. 85 Display:
Selector lever posi ­
tions
The selector lever position is shown in the instrument cluster
display by highlighting the appropriate symbol.
P -Park lock
In this position the gears are mechanically locked.
The park lock must only be engaged with the vehicle
stationary
=>& .
To engage P and to remove the lever from this position, you must
depress the release button (button in the selector lever handle)
and
simultaneously you must step on the brake pedal.
R -reverse
In this position, reverse is engaged. Reverse gear must only be engaged with the vehicle
stationary and
the engine running at idle speed=>& .
To engage R, you have to depress the release button
and simulta­
neously step on the brake pedal. In the R position, the back -up lights
illuminate with the ignition on.
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 103 in order to adjust the gear ratios to driving conditions
manually .
S -Sport setting
Th e 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 Nl,
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 _.,

The selector lever lock is effective only when the vehic le is
stationary and at speeds below 5 km/h . At higher speeds, the lock in
the N position is automatically sw itched o ff .
The selector lever is not locked when rapid shifts are made through
the N posi tion (e .g. from R to DI. 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 automatically.
Release button
The release button in the selector lever handle prevents accidental shifts into certain selector lever positions . When you press the
re lease button, the selector lever lock is cancelled. In the i llustra ­

Kick -dovvn feature
The kick-down feature allows maximum acceleration.
If you depress the accelerator pedal fully beyond the full-throttle
position, the transmission automatically downshifts one gear,
depending 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 slippery road -risk of skidding! •
Applies to vehicles : withs t ro ni c®
Launch Control Program
The Launch Control Program permits maximum accelera­
tion .
In order to use Launch Control, the ASR (Anti-Slip Regula­
tion) must be disabled. When ASR is disabled, the ESP
warning/indicator light 9 in the instrument cluster illumi­
nates . 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 ESP button.
The message "ASR off" appears in the instrument cluster
d isplay.
- Shift the gear lever to "S" or the tiptronic® position.
- Step on the brake pedal with your left foot and keep the
brake pedal fully depressed for at least one second.
Controls and equip ­
ment
- 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.
- 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. •
Applies to vehicles: with S tronic®
Back-up program
In the event of a system malfunction, there is an back-up
program.
In the event of system malfunctions, the automatic transmission
switches to the fail- safe mode. This is signalled by one segment or
all the segments in the display illuminating or going out .
Th e effect of a system malfunction can be one of the following:
• The program shifts only into certain gears.
• Reverse gear can no longer be engaged.

opener that does have not the safety stop and rever se feature as
required by federal safety standards . This includes any garage
door opener model manufactured before April 1 , 1982 .
• A garage door opener whi ch cannot detect an obje ct, signaling
the door to stop and rever se does not meet current federal safety
standard s. U sing a ga rage door opener without these features

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

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.
