The vehicle could begin rolling unintentionally,
depending on the hill or if towing a trailer.
.,. To prevent the parking brake from releasing au­
tomatically, pull and hold
the(®) switch and
press the accelerator pedal. The parking brake
remains set and prevents the vehicle from roll­
ing backward.
.,. You can release the C®l switch again once you
are sure that you are giving enough driving
force to the wheels by pressing the accelerator pedal.

You can use the emergency braking function in an
emergency situation, or if the standard brake op­
eration malfunctions or is disabled.
.,. Pull and hold the®) switch.
.,. As soon as you release the (®) switch or acceler-
ate, the braking stops.
Pulling and holding the
C®) switch while driving
the vehicle activates the emergency braking func­
tion. The vehicle is braked at all four wheels by
activating the hydraulic brake system. The brak­ ing effect is similar to heavy
braking¢&_ .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when

Driving
.,. Pull the®> switch to set the parking brake .
.,. Place the selector lever in the P position.
.,. Turn the engine off¢&_ .
.,. Turn the steering wheel when parking on in­
clines so that the wheels will roll into the curb
if the vehicle starts moving.
A WARNING
-
- Do not press the accelerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme­
diately and this could result in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners 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 accident.
- If the power supply fails , you cannot set the
parking brake if it is released . In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise children could start
the engine, release the parking brake or op­
erate electrical equipment such as power
windows, which increases the risk of an acci­
dent.
- 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
73

Drivin g
held with the br ake pedal. T he parking brake
eliminates the tendency to creep when a se­
lector lever pos ition is engaged . As soon as
you press the accelerator pedal, the park ing
brake releases automat ically and your vehicle
starts to move
¢ page 74 .
(D Tips
- Occasiona l noises when the parking brake is
set and re leased are normal and are not a
cause for concern .
- The park ing brake goes through a se lf-test
cycle at regular intervals when the veh icle is
stopped . Any noises associated w ith this are
no rmal.
- If there is a power fa ilure, the parking brake
will not set if it is released, and it will not r elease if it is
set¢ &. See an authorized
A udi dealer or authori zed Audi Servi ce Fa­
cility for ass istance.

Automatic transmission
Introduction
The au tomatic transmissio n is controlled elec­
t ronically. The transmission shifts up or down au ­
tomat ic al ly depen ding on which dr ive p rogr am is
selected .
When a
moderate driving sty le is used, the
t ransm iss ion selects the mos t econom ica l dr iv ing
mode. The tra nsmission upshi fts at a lowe r RPM
and downs hifts a t a higher RPM to improve fue l
efficiency.
The transmission sw itc hes to a sporty mode after
a kick- down o r when the dr iver uses a
s porty
dri ving style
characterized by quick acce lerato r
pedal movements, heavy acceleration, frequent
c h anges in sp eed and t raveling at the maximum
speed .

~ WARNING
-Always pay at tentio n to the traffic around
you when the cruise contro l system is in op­
eration . You are always respons ible for your
speed and the distance between your ve hi­
cle and other vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traff ic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rai n and
hyd roplaning), because this inc reases the
r is k of an accident.
-Switch the cr uise control off temporarily
when dr iv ing in turning lanes, highway exits
or in constr uction zones.

A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active . As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these condi­
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations .
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
A WARNING
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adaptive cruise control and braking guard
Assistance systems
offer distract you from the need to be alert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap­
tive cruise control cannot slow or brake the
vehicle safely when you follow another vehi­ cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used .
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody . That could affect the adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.
