parking brake
Fig. 94 Center console: parking brake
Your vehicle is equipped with an electromechani ­
cal parking brake ®
i=)fig. 94. The parking brake
is designed to prevent the vehicle from rolling
unintentionally and replaces the hand brake.
Setting/manually releasing the parking
brake
.. Pull the C®> switch to set the parking brake. The
LED in the switch turns on. The
-(USA mod­
els) . (Canada models) indicator light also
turns on in the instrument cluster display.
.. To release the parking brake manua lly, press
the brake or acce lerator pedal while the igni­
t ion is switched on and press
the(®) switch at
the same time. The LED in the button and the
indicator light in the display turn off.
Releasing the parking brake automatically
Requirement: the driver's door must be closed,

i=)page 82,
Starting to drive.
Preventing the automatic parking brake
release
The vehicle could begin rolling unintentionally,
depending on the hill or if towing a trailer.
Driving
.. 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<®> switch again once you
are sure that you are giving enough driving
force to the wheels by pressing the accelerator
pedal.
Emergency braking function
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 ho lding
the(®) 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
i=) ,& .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when the
<®l switch is pulled. Emergency
braking stops as soon as
the© switch is released
or the accelerator pedal is pressed.
Parking
.. Press the brake pedal to stop the vehicle.
.. Pull the<®> switch to set the parking brake .
.,. Select the P selector lever position .
.,. Turn the engine off i=) ,&.
.,. Turn the steering wheel when parking on in­
clines so that the wheels w ill roll into the curb
if the vehicle starts moving.
8_ WARNING
-Do not press the acce lerator 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.
-Eme rgency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed .
.,.

Drivin g
During emergency braking, your vehicle will
brake sim ilar to heavy brak ing. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather cond it ions
are bad, a full b rake applicat ion ca n cause
the vehicle to skid o r the rear end to swerve,
wh ic h increases the r is k of an accident.
- If the powe r supply fa ils, you cannot set the
par king b rake if it is re leased. In th is case,
par k the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion . See an authorized Audi dea ler or a u­
thorized Audi Service Facility for assistance .
- Always take the vehicle key with you when
leaving your vehicle, even fo r a short period
of time . This applies particular ly w hen ch il­
dren rema in in the vehicle. Otherwise ch il­
dren could start the engine, release the
park ing brake or operate electrical eq uip­
ment such as powe r windows, which in­
c reases the risk of an acc ident.
- No one sho uld rema in in the vehicle when it
is locked - especially ch ild ren. Locked doo rs
make it mo re diff icu lt fo r eme rgency wor k­
ers to get into the vehicle, which puts lives
at r is k .
0) Tips
When stopping at a traffic s ignal or stopping
in c ity traffic, you can set the parking b rake
manually. The vehicle does no t have to be
he ld w it h t he br ake peda l. The parking b rake
elim ina tes the tendency to creep when a se ­
lecto r lever position is engaged . As soon as
you p ress t he accelerator pedal, the parking
brake releases automat ica lly and your vehicle
starts to move
c::, page 82.
(D Tips
- Occasiona l noises when the parking brake is
set and re leased a re normal and a re not a
cause for concer n.
- The park ing bra ke goes thro ugh a se lf-test
cycle at regular intervals when the ve hicle is
stopped. Any noises associated w ith this a re
normal.
82
- If there is a powe r fail ure, the par king b rake
wi ll not set if it is released, and it wi ll not
re lease if it is
set ~.&. . See an a uth orized
Audi dealer or author ized Audi Se rvice Fa­
cility for assistance.
Starting to drive
Various convenience and safety f unct ions may be
available when the vehicle begins dr iving, de­
pendi ng on vehicle equipment .
Starting on hills with th e pa rking brake set
Requirement: the driver's door must be closed
and the driver's safety belt must be fastened.
.,. To sta rt driving comfortably when on a h ill, set
the parking brake and begin driving as usu a l.
The braking force of the parking brake does not
release automatically unt il the whee ls build up
