items using power are switched on, the equip­
ment that is current ly using the most power is
displayed.
A gauge @also shows the current tota l con­
sumption of all other consumers.
Economy tips
In certain situations, economy tips appear auto­

" 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

Selector lever emergency release
If the vehicle's power supply fails, the selector lever can be released in an emergency.

l ector lever
"' To reach the emergency release mechanism, re­
move the ashtray insert*.
"' Loosen and remove the small cap in the ashtray
mount
c:> fig. 86 .
.. You now have access to a pin. Using a screw­
driver or similar object, press the pin down and
hold it in that position .
.. Press the release button in the selector lever
and move it into the N position.
Only move the selector lever out of the P position
when the ignition is switched on. If the vehicle
must be pushed or towed due to a power failure
(for example, the vehicle battery is drained), the
selector lever must first be moved to the
N posi­
tion using the emergency release mechanism .
A WARNING
-Only activate the emergency release while
on a level surface or a slight slope.
-Only move the selector lever out of the P po­
sition when the parking brake is set. If it is
not functioning, secure the vehicle from
rolling using the brake pedal or other suita­
ble means, such as blocking a front and a
rear wheel. An unsecured vehicle may roll
away, which increases the risk of an acci­
dent.
