The selector lever must be in Nor P. If one of the driving positions
is e ngaged a sa fe ty swit ch will preven t the eng ine from bei ng
started. See
also=:> pa ge 130 .
Before you move the selector lever from the P pos ition, you m ust
a lways apply the b ra ke pe dal be fore and wh ile depress in g th e
button in the hand le of the selecto r lever.
& WARNING
• Unintended vehicle movement can cause seriou s injury .
- When the selector lever is in a driving position , the vehicle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
be cause power is tran smitted to the wheels as soon as a
driving position is engaged .
- Do not accelerate while select ing a driving position . At th is
time the engine must be at idle speed so that undue stress is
not placed on the clut ches in the transmi ssion .
- Remember: -even when stopped briefly with the automatic
transmission in
" D " or "R ", engine power is being transmitted
to the wheels . Your vehicle could "creep " forward or backward.
When stopped , keep the brake pedal fully depressed and use
the parking brake if necessary to keep the vehicle from rolling.
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before sele cting a driving posi ­
tion.
• Never shift into
" R " or "P " when the vehicle is in mot ion .
• Never get out of the dri ver's seat when the engine is running .
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly .
• If the engine must remain running , never have any driving posi ­
tion engaged when checking under the hood . Make sure the
selector lever has securely engaged and is locked in
"P" with the
parking brake firmly
set => page 299, "Engine compartment ".
& WARNING (continued )
Otherwise , any increase in engine speed may set the vehi cle in
motion , even with the parking brake applied . •

for more than approximate ly 1 second, without the brake peda l
being pressed.
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N pos ition .
Interlock button
The lock button on t he se lector lever prevents the lever from being
accidentally shifted into certain positions. Pressing this button
deactivates the selector lever lock. Depending on the direction of
the shift, the selector lever locks at different positions . The positions

Kick-down
T he kick-down feature allows the vehicle to generate
maximum acceleration.
When you press t he accelerator peda l beyond the resistance point
that is reached at ful l throttle, the transmission will select a lower
gear ratio based on vehic le speed and engine RPM. The engine RP M

Dynamic shift program (DSP)
T he aut omatic transmission is electronically controlled.
T he transmission is self adapting and wi ll autom ati ca lly select the
best shift program suited to t he driving condi tions and drivi ng s tyle.
The transmission will se lect one of the
eco nom y programs when
you drive at a steady speed or a gradual ly changing speed without
heavy acce leration . T his achieves optimum fuel efficiency, with ear ly
upshifting and delayed downshifting .
T he trans mission wil l automat ica lly select the
s porty shift programs
when you drive at higher speeds, or with heavy acce leration and
frequen tly changing speeds . Upshifts are de layed to make full use
of engine power. Down shifting takes place at higher engine speeds
t han in the economy programs .
The selection of the most suitab le shift program is a continuous,
automatic process . The driver can also make the transmission
switch to a sporty program by
quickl y pressing down the gas peda l.
T his causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g . for quickly passing ano ther veh ic le .
You do not need to press the gas pedal into the kick-down range .
After the transmission has upshifted, t he original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to select the proper gear for uph ill and downh ill gradients.
T his prevents the transmission from upshifting and downshifting
unnecessa rily on hi lls. The transmiss ion will shift down to a lower

To upshift
Push the selector lever forward to the plu s position 0
~ fig. 186.
To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears
1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you apply a light thrott le when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear.
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic® wi ll downshift from the selected gear into
the next lower gear until it reaches 1st gear, based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the throttle again.
[ i ] Tips
• When you shift into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission will shift down
to a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic® is inoperative when the transmission is in the fai l-safe
mode .•

Fail-safe mode
If tiptronic® suffers a ma/function, the fail-safe mode
maint ains minimum driveability.
In the event of particular system malfunctions, the automatic trans ­
mission switches to the fail -safe mode . This is signalled by all the
segments in the disp lay il lum inating or going out .
You can continue to move the selector lever to a ll positions. The
manual shift program (tiptronic) is switched off in the fail-safe
mode . I
n selector lever positions D and Sand in the manual shift program,
the transmission remains in 3rd gear if 1st, 2nd or 3rd gear was engaged previous ly. The transmission rema ins in 5th gear, if 4th, 5th
or 6th gear was engaged previous ly .
The next time you drive o ff or start the engine, 3rd gear is engaged .
You can continue to use reverse gear . But the electronic lockout for
r everse gear is turne d of f.
0 Note
If the transmission switches to fail -safe mode, you should ta ke the
vehic le to an authori zed Audi dealership as soon as possible to have
the condition co rrected. •

Dis tance wa rn ing is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MM I
=> page 180.
Mute
I n t he case of vehic les with automatic transmission, an acoustic
distance warning is discontinued when the transmission selector
Controls and equip­ ment lever is moved to the P position
. However, the system remains
active . As soon as the selector lever is moved fro m the
P pos it ion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes.
Dr iving fo rw ard /b ac kw ard
Dista nce warn ing w hen driving fo rward/ backward is based on
detection of an obstac le in the range of the parking assist. As the
distance decreases, t he time interval betwee n the aud ible t ones
becomes shorter.
When the distance is less than approx .
1 ft (0.30 m), the tone
becomes cont inuous. At th is po int you shou ld stop backing up or
driving forward .
I f the distance to an obstacle re m ains the same, the vo lume of the
distance warning is gradua lly reduced after about
4 seconds (does
not app ly to the zone for the continuous tone). If you start to
approach the detected obstacle again, the distance warning will
sound at the norma l volume again.
P arking
When you se lect another gear when park ing (e .g . reverse/forwa rd),
the warning tones are temporarily suppressed, but the visua l
display remains on the MMI display . If you start approaching a
detected obstac le again, the distance warning wi ll sound at the
normal volume again .
Vi su a l displa y
The segments on t he MMI d isp lay indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstac les in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer t he
segments approach the
vehic le => page 170, fig. 193. When the
seg ment before last is d isplaye d, the ve hicle has reac hed the coll i­
sion zone. At this point you should stop backing up or driving
f orward

Driving and environment
The first 1,000 miles (1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
For the first 600 miles (1,000 kilometers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
- Speeds can gradually be increased to the maximum
permissible road or engine speed.
During and after break-in period
-Do not rev the engine up to high speeds when it is cold.
This applies whether the transmission is in N (Neutral) or
1n gear.
After the break-in period
- Do not exceed maximum engine speed under any
circumstances.
- Upshift into the next higher gear
before reaching the red
area at the end of the tachometer
scale => page 12.
Controls and equip­
ment Safety first
Vehicle operation
During the first few hours of driving, the engine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break-in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 kilometers).
0 Note
Extremely high engine speeds are automatically reduced. However,
these rpm limits are programmed for an engine well run-in, not a
new
engine.
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .•
New tires
If your vehicle is running on new tires, drive particularly
careful for the first 350 miles (500 kilometers) after fitting.
& WARNING
New tires tend to be slippery and must also be "broken-in". Be
sure to remember this during the first 350 miles (500 kilometers).
Brake
gently. Avoid following closely behind other vehicles or
other situations that might require sudden, hard braking.
