~ Turn the eng ine off ¢,&. .
~ Applies to: manual transmission: Engage 1st
gear.
~ Turn the steering wheel when parking on in ­
clines so that the wheels will roll into the curb
if the veh icle starts moving .
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.
Starting to drive
Various convenience and safety funct ions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the p arking brake set
Requirement: the driver's door must be closed .
~ 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 a utomatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hi ll ho ld assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.

Difficult ter rain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps, etc.).
To prevent the veh icle from bottoming out and to
reduce the risk of underbody damage, you sho uld
d rive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneve n are a, instead of driving across the
center of the uneven area with a ll four wheels .
Drive quick ly through sandy or marshy off-road
sections and do not stop, if at all possible.

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.

lects a gear that is suitable for the hill. Hill de­

ieved at the time of braking, within physical and
technical limitations. If may still be necessary to
adjust the speed with the brake pedal.
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.

limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.
