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.
