_& WARNING
- Never ac celer ate o r release the clutch pedal
carelessly when a gear or a selector lever
posit ion (automatic transm ission) is engag­
ed wh ile the vehicle is stationary and the
en­
gine is runn ing. 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
bra ke sim ila r to heavy brak ing . ESC and the
associated components (ABS, ASR, EDL)
c annot overcome the laws of physics.
Around curves and when road or weather conditions are bad, a fu ll 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 t ransm iss ion). See an
authorized Aud i dealer o r 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. Th is app lies p articu larly when
children rema in in the vehicle. Otherwise,
D riv ing
children could start the engine, release the
parking brake or operate e lectrical equip­
ment such as power w indows, which
in­
creases the risk of an accident.
- No one, especially children, should remain
in the vehicle when it is locked. Locked
doors make it more difficu lt for emergency
wo rkers to get into the vehicle, which puts
lives at risk .
(D Tips
Applies to: vehicles with automatic transmissions
When stopp ing at a t raff ic signa l or stopp ing
i n city traffic, yo u can set the park ing bra ke
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 accelerator peda l, the parking
brake re leases automatically and your vehicle
starts to move
c>page 95.
(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 regu lar intervals when the vehicle is
stopped. Any no ises assoc iated with th is are
normal.
- If there is a power failure, the parking brake
w ill not set if it is released, and it will not
release if it is set

Automatic transmission
Introduction
Applies to: vehicles with automatic transmissions
.
The aut omat ic transmission is controlled elec­
tronica lly. The transmission shifts up or down au­
tomatically depending on which drive prog ram is
selected.
When a
moderate driving style is used, the
transmission se lects the most economical driving
mode. The transmission upshifts at a lower RPM
96
and downshifts at a higher RPM to improve fue l
effic iency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty
driving style
characterized by quick accelerator
pedal movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed .
If desired, the driver can also select the gears
manually (tiptronic mode) c:;, page 99.
S tronic transmission
The S tron ic is a dual-clutch transmission. Power
i s transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in traction .
tiptronic transmission
In the tiptronic transmission, power is transfer­
red by a torque converter.
Selecting a selector lever position
Applies to: vehicles with auto matic transmissions
Fig. 102 Cente r console: se lector lever
The current se lecto r lever position is shown next
to the selector lever
c:;, fig. 102 . The current se­
l ector lever position is also shown in the instru­
ment cluster display .

Driving
to engage the S sport mode. You can only select
the S selector lever position when the D or E posi­
tion is selected. To select the Dor
E position
again when S is engaged, move the selector lever
back ¢,& . To shift from N to D when traveling at
speeds below
1 mph (2 km/h), press the brake
pedal and shift into the D
position ¢,& .
In the normal mode D, the transmission auto­
matically selects the suitable gear ratio. It de­
pends on engine load, vehicle speed and driving
style .
Select the
sport mode S for sporty driving. The
vehicle makes full use of the engine's power.
Shifting may become noticeable when accelerat ­
ing.
The S selector lever position engages automati­ cally when you select the
dynamic mode in drive
select* .
A WARNING
Read and follow all WARNINGS.
- The vehicle can roll even if the ignition is
switched off .
- Power is still transmitted 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 in all selector
lever positions (except P and N) when the
engine is running.
- Before opening the hood, select the P selec­
tor lever position and set the parking brake.
This reduces the risk of an accident. Always
read and follow the applicable warnings
