Sensors are located in the front and rear bump­
ers. If these detect an obstacle , audible and visu­
al signals warn you.
Make sure the sensors are not covered by stick­
ers, depos its or any other obstructions as it may
impair the sensor function. For information on
cleaning, see

The display field begins approximately at:
® 4 ft (1.20 m)
® 3 ft (0.90 m)
© 5.2 ft (1.60 m)
@ 3 ft (0.90 m)
The closer you get to the obstacle, the shorter
the interval between the audible signals. A con­
tinuous tone sounds when the obstacle is less
than approximately 1 foot (0.30 meters) away.
Do not continue driving forward or in reverse

side of the vehicle's path . Red segments show
identified obstacles that are in your vehicle's
path. As your vehicle comes closer to the obsta­
cle, the segments move closer to the vehicle . The
collision area has been reached when the next to
last segment is displayed . Obstacles in the colli­

Parking syste m s
-For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck. Do not
use the orientation lines in this case.
- If driven from a level surface onto an in­
cline, or a downward slope.
- If driven toward protruding objects.
- If the vehicle is carrying too much load in
the rear.
- The accuracy of the orientation lines and
blue surfaces decreases when the vehicle is
raised/lowered

Intelligent Technology
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management,
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this .
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge level.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life are
limited.
- When the starting ability is endangered, the
(•) indicator light turns on ~ page 21.
132
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when driving short distances, during city driving,
and at cold times of the year . A lot of energy is
used but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is
used but none is generated.
In situations like this, energy management will
actively regulate the distribution of energy.
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually scaled
back or switched off . This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances. These convenience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will drain if you use Infotain­
ment functions such as listening to the radio
while the engine is switched off.
If the starting ability is impaired by the energy
use, the following message will appear in the In­
fotainment system display:
Please start the engine, otherwise the system
will turn off shortly.
This message indicates that the system will
switch off automatically after 3 minutes. If you
would like to continue using the functions, you
must start the engine.
With the engine running
Although electrical energy is generated while
driving, the vehicle battery can drain. This can
happen if little energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.

Traffic safety information
Audi recommend s performing certain Infotain­
ment system fun ctions, such as entering a desti­
nation, only when the vehicle is stationary . Al ­
ways be prepared to stop operating the Infotain­
ment system in the interest of your safety and
the safety of other road users.
_& WARNING
Only use the Infotainment system when traf­
fic conditions permit and always in a way that
allows you to maintain complete control over
your vehicle.
Introduction
T he Multi Media Interface , or MMI for short ,
combines various systems for communication,
naviga tion and entertainmen t in your Audi. You
can operate the MMI using the MMI control pan­
el, the multifunction steering wheel or the voice
recognition system* .

Switching the MMI on
and off
The MMI switches on and off automatically with
the ignition. It can also be switched on or off
manually .
-Switching on manually: press the On/Off knob
® briefly c::;, page 135, fig. 153 . Or: press the
IM ENU I button or one of the buttons to directly
open the
menus @,:::;, page 136, fig . 154 .
When the system is switched on, the last menu
that was selected is displayed and the last audio
source that was selected begins playing .
-Switching off manually: press and hold the
On/Off
knob ® c::;, page 135, fig. 153 until the
MMI switches off.
If the MMI has been switch­
ed off manually, it does
not switch on again au­
tomatically the next time the ignition is switch­
ed on.
The MMI can still be operated for approximately
ten minutes after switching the ignition
off. If
you do not press any buttons or the control knob
on the MMI control panel with in this time, the
MM I switches
off automatically.
a) Tips
-The MMI switches off automatically if the
engine is not running and the veh icle bat­
tery is low.
-There may be delays when extending or re­
tracting the display.
Adjusting the volume
The volume of an audio source or a system mes­
sage (for example, from the voice recognition
system) con be adjusted directly while the sound
is playing using the On/Off knob.
-Increasing or decreasing the volume: turn the
On/Off
knob ® c::;, page 135, fig. 153 to the
right or left.
- Muting or pausing : press the On/Off knob@
,:::;,page 135, fig. 153 briefly . Or: turn the On/
Off knob to the left . ..,.
