A WARNING
- Do not press the acce lerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the eng ine is running . Oth­
erwise, the vehicle will start to move imme­
d iate ly and this could resul t in an accident.
- Emerge ncy brak ing should only be used in
a n emergency, when the norma l bra ke pedal
has fa iled or the bra ke peda l is obstr ucted.
D ur ing eme rgency bra king, you r vehicle w ill
brake s imilar to he avy braking. ESC and the
associated components (ABS, AS R, EDL)
cannot overcome the laws of physics.
Around curves and when road or weather
conditions a re bad, a full brake applicat ion
can cause the veh icle to skid or the rear end
to swerve, wh ich increases the risk of an ac­
cide nt.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
pa rk the veh icle on leve l ground and secure
it by p lac ing the sele cto r leve r in the P pos i­
tion. See an au thor ized A udi dealer or au ­
thor ized A udi Se rvi ce Fa cility for assis tan ce.
- I f you leave the vehi cle, sw itch the ignition
off and take the veh icle key wi th yo u. Thi s
app lies pa rticular ly when children remain in
the vehicle. Otherwise, chi ld ren co uld start
the engine, release the parking brake or op ­
erate e lectr ica l equipment s uch as power
w indows, wh ich increases the r isk of an acci­
dent.
- No one, especially c hildren, should rema in
in the vehicle when it is locked. Locked
doors make it more difficu lt for emergency
workers to get into the vehicle, which puts
lives at ris k.
(D Tips
When stopp ing at a traff ic signa l or stopp ing
i n city traffic, you can set the park ing brake
manually . The veh icle does not have to be
h eld with the brake pedal. The par king b rake
e liminates t he tendency to creep when a

selector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move
¢ page 83.
(D Tips
- Occasional noises when the parking brake is
set and re leased are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
- If there is a power failure, the parking brake will not set if it is released, and it will not
release if it is
set¢&. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance .
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment.

Automatic transmission
Introduction
Applies to: vehicles with automatic transmiss ions
T he automatic transmission is controlled elec­
tronically . Upshifting and downshifting occur au­
tomatically.
When a
moderate driving style is used, the
transm ission selects the most economica l dr iv ing
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
In the "S" selector lever position, the transm is­
sion switches to a sporty mode after a kick-down
or when the driver uses a
sporty driving style
characterized by quick accelerator pedal move­
ments, heavy acce leration, frequent changes in
speed and traveling at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 88, Manual
shifting (tiptronic mode).
The S tronic is a dual-clutch transmission. Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
.,.

Stopping temporarily
• Keep the vehicle st ationary using the bra kin g
peda l, for examp le a t traffic ligh ts.
• Do not press the acce le rato r pedal when doing
this.
• To prevent the vehicle from rolling when you start driving, set the pa rking brake when stop­
ping on steep
hills ¢.&. and ¢(Q).
• The parking brake will release a utomat ica lly
and the vehicle will start moving once yo u press
the acce le rato r pedal. Requirement: the d riv­
er's doo r mus t be closed.
Stopping/parking
If the selector lever is not in the "P" pos ition
whe n you open the d river's door, the vehicle
could roll. In vehicles with a conven ience key *,
the message :
Shift to P, otherwise vehicle can
roll away. Door s do not lock if lever is not in P
appe ars . A wa rning tone wi ll also sound.
• Press and hold the brake peda l¢ ,&. .
• Set t he par king brake.
• Select the "P" se lector lever posi tion .
Un der certai n circumstances, (such as dr iving in
the mo unta ins or towi ng a trailer), it may be use­
ful to switch temporar ily to the m an ual shift pro­
gr am in or der to ad ju st t he gears to the driv ing
cond it ions by hand ¢
page 88.
When parking on a level surface, s imp ly place the
se le ct or lever i n the "P" pos ition. On inclines, a c­
tivate the par king b rake first and then move the
se lector lever to the "P " posit ion ¢
page 81. Thi s
prevents the locking mechanism from being
l oaded too heavily and will make it easier to
move the selector lever out of the "P" position.
A WARNING
- The vehicle can roll even whe n the engi ne is
sw itched off .
- Unintended vehicle movement can lead to
serio us injuries.
- Never leave your veh icle with the engine
r u nning while in gear. If you must leave
your veh icle when the eng ine is r unning, set
t he par king brake and move the se lecto r lev ­
er to the "P " posi tion .

u. 00 .-< N l'­ N .-< 0 N > 00
-Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D", "S" or "R" position or "tiptronic"
mode is selected.
- Do not inadvertently press the accelerator
peda l when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the acce lerator pedal when changing
the selector lever position while the vehicle is stationary and the engine is running.
- Never engage the "R" or "P" selector leve l
positions while driving. It could cause a
crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"ti ptron i c".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in p lace with the foot brake or
park ing brake to prevent it from rolling
back.
- Never hold the veh icle on an incline with a
sl ip ping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
¢ page 89 when
the clutch is over loaded .
{LlJ) Note
- When stopping on an incline, do not try to
ho ld the vehicle in place by pressing the ac­
ce lerator pedal while a driving gear is se ­
l ected. This can cause the automatic trans ­
mission to overheat and can damage it. Set
Driving
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
"N" position will damage the automatic
transmission, because it is not lubricated
under those circumstances
¢ page 3 78,
Towing with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. When the
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool¢
page 89.
(D Tips
For safety reasons, the park ing brake only re­
l eases automatically when the driver's door is
closed.
Hill descent control
App lies to : vehicles wi th automatic transmiss ions
The hill descent control system assists the driver
when driving down hills.
Hill descent control is act ivated when the selec­
tor lever is in the "D" or "S" posit ion and you
press the b rake pedal. The transmission auto ­
matically se lects a gear that is suitab le for the
hill. Hill descent contro l tries to ma inta in the
speed achieved at the time of braking, within
physical and technica l limitations. If may still be
necessary to adjust the speed with the brakes.
Because hill descent control cannot shift down
farther than 3rd gear, it may be necessary to
shift into tiptronic mode in very steep areas . In
th is case, shift into 2nd or 1st gear in t iptronic
mode to use the engine's braking force to rel ieve
the brakes.
Hill descent control switches
off once the hill lev­
els out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢ page 120, hill descent control is also activated
when the speed is set .

& WARNING
Hill descent control cannot overcome phys ical
limitations, so it may not be able to maintain
a constant speed under all condit ions. Always
be ready to apply the brakes .

The tra nsmission a utomatically sh ifts up or dow n
before cr itical engine speed is reac hed.
Applies to: RS models: when accelerating, the
transm iss ion does
not au tomatically shift to the
next gear short ly before the maxim um permitted
engine RP M is re ached. Shift to the next highest
gear at the right time.
The tra nsmission on ly allows manual shifting
whe n the engine speed is w ith in the perm itted

Kick-down
Applies to: vehicles with automatic transmissions
Kick-down enables maximum acceleration.
When you p ress the accelerator pedal down be­
yo nd the res istance point (called kick-down), the
automat ic transmission downshifts into a lower
gear, depending on vehicle s peed and engine
RPM .
It shifts up into the next higher gear once
t h e maximum specified engine RPM is reached .
Applies to: RS models: in tipt ronic mode, the
transm iss ion does
not automa tic ally shift down
i nto a lower ge ar. If yo u m ust accelera te, for ex ­
ample to pass a vehi cle, you mus t sh ift manually .
