... Bring the steering wheel into the desired posi­
tion .
... Push the lever against the steering column un­
t il it is secure.
A WARNING
Incorrect use of the steering wheel adj ust­
ment and an incorrect seating posi tion can
cause se rious injuries.
- Only adjust the steering column when the vehicle is stat ionary so that you do not lose
cont ro l of the ve hicl e.
- Adjust the dr iver's seat or steering wheel so
that there is at least a 10 in (25 cm) d is­
t an ce betwee n your chest a nd the s teering
w heel. If you d o not m aint ain this dis tance,
yo u will no t be proper ly protected by the a ir­
bag system.
- If your phys ic al characteris tic s preven t you
from sit ting at least 10 in ( 25 cm) or mo re
away from the steering wheel, see if yo ur
authorized Audi dealer or autho rized Audi
Service Facility can prov ide adapters that
will help.
- If your face is level with the steering wheel,
the a irbag does not provide as much protec­
t io n during a collision. A lways make s ure
that the steering wheel is level with you r
chest.
D rivi ng
-Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock pos i­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the stee ring wheel.
H old ing the steer ing whee l incorrect ly sig­
n ificant ly increases the r isk of injury to the
hands, a rms and head if the airbag deploys.

Driving
-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­
gine is
off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
(D Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
{D) Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch
off af­
ter a certain amount of time . Make sure that
electrical equipment such as the exterior
lights are switched
off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the
I START ENGINE STOPI button
¢ page 59, fig. 67.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned
off while driving at speeds starting at
4 mph (7 km/h). To switch the engine
off, press
the
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
_&. WARNING
- Never turn off the engine before the vehicle
has come to a complete stop.
60
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine
off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the
result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after th@ engine is
switched
off and there is a risk of damaging
the engine . For this reason, let the engine run
at idle for approximately two minutes before
shutting it
off.

.&. WARNING
- Do not press the acce lera to r pedal inadve r­
tently if a gea r is selec ted whe n the vehicle
is st ation ary and the e ngine is runni ng. Oth­
erwise, the vehi cle will s tart to move imme­
diate ly and this could result i n an accident.
- E mergency brak ing sho uld only be used i n
an emergency, when the norma l bra ke pe dal
has failed or the brake peda l is o bstr ucted .
During emergency brak ing, your vehicle will
brake s imilar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot ove rcome the laws of physics. In co r­
ners and when road or weather conditions
are bad, a fu ll brake application can cause
the vehicle to s kid or the rea r end to swe rve,
whi ch in crease s the risk of an ac cident.
- I f the power supply fails, you cannot set the
pa rking bra ke if it is released. In this ca se,
p ar k the vehicle on leve l grou nd and secure
it by plac ing the sele ctor lever in the P pos i­
tion. See an authorized A udi dealer or au -
thorized A udi Service Facil ity for assistance.

-Always take the vehicle key with you when
leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it
is locked - especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move ~page 63.
(D Tips
- Occasional noises when the parking brake is
set and released 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
q Li::,.. 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.
Starting on hills with the parking brake set
Requirement: the driver's door must be closed.
Driving
.. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­ er is maintained for a brief moment
q & to pre­
vent the vehicle from rolling back when starting .
During this time, you can easily begin to move
your vehicle.
& WARNING ~
App lies to: veh icles with hill hold assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately.
- The intelligent technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks.
- Hill hold assist cannot hold the vehicle in
place on all hills (for example, if the ground
is slippery or icy).
- To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically­
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the .,..

When parking on a level surface, simply place the
selector lever in the P position. On inclines, acti­
vate the parking brake first and then move the selector lever to the P position ¢
page 62. This
prevents the locking mechanism from being
loaded too heavily and will make it easier to

.8, WARNING
- The vehicle can roll even when the engine is
switched off.
- Unintended vehicle movement can lead to
serious injuries.
- Never leave your vehicle with the engine
running while in gear.
If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- 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, Sor R position or "tiptronic" mode is
selected.
- Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other­
wise the vehicle will start to move immedi­ ately, even if the parking brake is set. This
could result in a crash.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running .
Driving
-Never engage the R or P selector level posi­
tions while driving. It could cause a crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with "ti ptronic".
- 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 place with the foot brake or
parking brake to prevent it from rolling
back .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
mJ indicator light turns on
and a message appears ¢
page 70 when
the clutch is overloaded.
- If the engine must run while you are work­
ing in the engine compartment with the
hood open, make sure a gear is not engag­
ed. The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set ¢
page 235. Other­
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set .
(!) Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans­
mission because it is not lubricated under
those circumstances.
67

Driving - 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
@] or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool

-Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans ­
mission because it is not lubricated

@ Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control is ac tivated when the selec­
tor lever is in the Dor S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical and
technical limitations.
If may still be necessary to
adjust the speed with the brakes. Because hill de ­
scent control cannot shift down farther than 3rd
gear, it may be necessary to shift into tiptronic
mode in very steep areas. In this case, shift man­
ually into 1st or 2nd gear in tiptronic mode to
use the engine's braking force to relieve 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 72, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.
