" N .... 0 0 \,;J ' Releasing the parking brake automatically
Requirement: the driver's door must be closed,
the driver's safety belt must be latched and the
parking brake must be set.
.,. To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addition to releasing the parking brake auto­
matically, other convenience and safety functions
are available when you start driving
¢page 74,
Starting to drive.
Preventing the automatic parking brake
release
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.
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 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
the®> 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.
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

a co .... N
" N .... 0 0 \,;J ' Intelligent Technology Electronic stabilization
control (ESC)
Description
Electronic stabilization control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc­ ing engine torque. As soon as the ESC is actively
regulating, the
If] indicator light b links in the in­
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is act ing to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat ion is over . In veh icles
with adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv ing ahead is too small. On
vehicles with activated and functioning night vi­
sion assist*, the brake assist system can respond more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels (if the vehicle is
Intelligent Technology
equipped with a ll wheel drive*). This function is
not avai lab le at higher speeds.
In extreme cases , EDL automatically switches off
to keep t he brake on the braked whee l from over ­
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle stability
through steering .
Selective wheel torque control
Selective wheel torque control is used when driv­
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on the ins ide of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
tional collisions after an accident. If the airbag
contro l module
detects a co llision above a certa in
vehicle speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
-
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
p hys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
g in acting to stabilize yo ur vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the risk of a coll ision increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when
