h _e _ ro_ a_d __________________________________________________ _
Starting off with a trailer To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar to making an emergency
stop~ &.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released
, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Please release parking brake
This message appears, when a gear is selected and the accel erator
pedal is depressed -release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .
~ Parking brake malfunction !
This driver message appears together with the yellow 'Jlf symbol
when there is a parking brake malfunction.

The image in the visual display can be switched off on the MMI
display=> page 182. The acoustic distance warning remains active.
If you press a function button on the MMI terminal, the visual
display disappears. Manually switching the parking assist on again
via the
P, Yi switch shows the visual image on the MMI display again .
Further informat ion regard ing the MMI terminal is included in the
MMI user 's manual.
Rear-view camera (rear view)
The rear-view camera picture=> page 175, fig. 198 appears on the
MMI display as a mirror image. The rear -view camera picture has
orientation lines and marked surfaces projected into it as an aid to
the parking
process => page 173. The red line in the picture
=> page 173, fig. 194 or=> page 173, fig. 195 indicates the collision
area . You should stop backing up, preferably before you reach this
point =>& .
If your vehicle is close to an obstacle, the visual distance display
also appears in the picture from the rear -view camera. This superim ­
posed display is intended to help display the relevant critical vehicle
area.
If the visual display is shown on the MMI display and you press the
control button with the
Rear view function=> page 170, fig. 193, the
picture from the rear -view camera is displayed.
If the picture from the rear-view camera is shown and you press the
control button with the
Graphic function => page 175, fig. 198, the
visual display is shown.
The picture from the rear-view camera can be switched off on the MMI
display => page 182. The acoustic distance warning remains
active.
If you press a function button on the MMI terminal, the rear -view
camera picture disappears. The rear-view camera picture reappears
the next time you park. But the picture from the rear -view camera
can also be shown again on the MMI display by manually switching
off and on with the
P' Yi switch . Further information regarding th e
MMI terminal is included in the MMI user 's manual.
& WARNING
• Sensors have dead spaces in which objects cannot be
detected. Be especially careful to check for small children and
animals before backing up . Small children and animals will not
always be detected by the sensors.
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers . Always watch where you are driving and
make sure that nothing is in the way.
• Remember that low obstacles which have already been
signaled may pass below the system's sensing zone when the
vehicle is backing up. The fact that the signal stops does not mean
that you have cleared the obstacle. When the signal stops, impact
is imminent. Objects such as trailer hitches, chains, narrow posts
or fences covered by a thin layer of paint may not always be
detected by the system. They can still damage your vehicle
without warning.
• Always make sure that the volume and frequency of the chimes
is adjusted so that you can easily hear the acoustic distance signal
even if the radio is playing, the air-conditioner blower is on High or
there is a high level of outside noise.
- Check the settings whenever someone else has driven the
vehicle before you.
• Improper reliance on the Audi parking system can cause colli­
sions and serious personal injury.
- Never rely only on parking assist when backing up.
- Always check rear view mirrors to make sure it is safe to back
up.
[ i] Tips
• The rear-view camera picture is available as soon as the MMI
Display or the MMI is switched on, or the start -up phase is
completed .
