_&. WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the
vehicle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steering wheel so
that there is at least a 10 in (2S cm) dis­
tance between your chest and the steering
wheel. If you do not maintain this distance,
the airbag system will not be able to provide
its full protection.
-If your physical characteristics prevent you
from sitting at least 10 in (2S cm) or more
away from the steering
wheel, see if an au­
thorized Audi dealer or authorized Audi
Service Facility can provide adapters that
will help .
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision . Always make sure
that the steering wheel is level with your
chest.
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi­
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 steering wheel.
Holding the steering wheel incorrectly sig­
nificantly increases the risk of injury to the
hands, arms and head if the driver airbag
deploys .

A WARNING
-Never accelerate or release the clutch pedal
carelessly when a gear or a selector lever
posit ion (automatic transmission) is engag­
ed whi le the vehicle is stationary and the en­
gine is running. Otherwise, the vehicle will
start to move immediately and this cou ld re­
sult in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake peda l
has failed or the brake pedal is obstructed.
During emergency braking, your veh icle will
brake sim ilar to heavy brak ing . ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics,
Around curves and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end
to swerve, which increases the risk of an ac­
c ident.
- If the power supply fails, you cannot set the
park ing brake if it is released . If th is is the
case, stop the veh icle on leve l ground and
secure it by engaging 1st gear (manual
transmiss ion) or select ing the P selector lev ­
er position (automatic transm iss ion). See an
authorized Aud i dealer or autho rized Aud i
Service Facility for assistance .
- Always take the vehicle key with you when
leaving your vehicle, even if for a short pe ri­
od of time. This applies particu larly when
children remain in the vehicle. Otherwise,
children could start the engine, release the
parking brake or operate electrical equip­
ment such as powe r windows, which in­
creases the risk of an acc ident.
- No one, especially children, shou ld remain
in the vehicle when it is locked. Locked
doors make it more difficult for emergency
D riving
workers to get into the vehicle, which puts
lives at risk.
(D Tips
Ap plies to : vehicles with auto matic transmissions
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 vehicle does not have to be
held with the brake pedal. The park ing brake
eliminates the tendency to creep when a se­
l ector lever position is engaged. As soon as
you press the a ccelerator peda l, the parking
brake releases automatically and your vehicle
starts to move r=;,
page 89.
(j) Tips
-Occasional noises when the pa rking brake is
set and released are normal and are no t a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises assoc iated with this are
normal.
- If there is a power failure, the parking brake
wi ll not set if it is released, and it will not
re lease if it is
set ¢.&. . See an a uthorized
Audi dealer or authorized Audi Service Fa­ cility for assistance.

Automatic transmission
Introduction
Applies to: vehicles with automatic transm issions
The automat ic transmission is controlled elec­
tronically. The transmission shifts up o r down au­
tomatically depend ing on which drive program is
se lected .
When a
moderate drivi ng style is used, the
transmission selects the most economical driving
mode. The transmiss ion upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transm ission switches to a sporty mode after
a kick-down or when the driver uses a
s po rty
d rivi ng style
character ized by quick accelerator
pedal movements, heavy acceleration, frequent
D rivi ng
changes in sp eed and traveling at the maximum
speed.
If des ired, t he d river can also se lect the gea rs
manually (tiptronic mo de) ¢ page 94 .
S tronic transmission
The S tron ic is a dual-clutch transmission . Power
is transferred using two clutches that work inde­
pendent ly from one another. They rep lace the
torque conve rter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In th e tiptronic transmission, power is t ransfer­
red by a torque conve rter.
