2013 AUDI A4 radio controls

Turn the knob to the desired position:
Q/ P -In this position , you can adjust the
driver's and front passenger's exterior mirrors
by turning the knob in the desired direction.
(ijjl -The mirrors are heated depending on the
outside temperature.
8 -The exterior mirrors fold in*. You can ad­
just whether or not the mirrors fold in auto­
matically when locking the vehicle using the
radio/MM I*
c::> page 3 7.
Passenger exterior mirror tilt function*
(only with memory for exterior mirrows)
To help you see the curb when backing into a
parking space, the surface of the mirror tilts
slightly . The knob must be in the
P position
for this to happen .
You can adjust the tilted mirror surface by
turning the knob in the desired direction .
When you move out of reverse and into anoth ­
er gear, the new mirror position is stored and
assigned to the key you are using.
The mirror goes back into its original position
once you d rive forward faster than 9 mph
(15 km/h) or switch the ignition off .
,&. WARNING
Curved mirror surfaces (convex or spheri­
cal*) increase your field of view. Remem­
ber that vehicles or other objects will ap­
pear smaller and farther away than when
seen in a flat mirror. If you use this mirror
to estimate distances of following vehicles
when changing lanes, you could estimate incorrectly and cause an accident.
(D Note
- If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mir­ ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror .
-If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
-

the mirrors . Never fold power folding ex­
terior mirrors* by hand. Only fold them
in and out using the power controls.
(D Tips
- The exterior mirror settings are stored
with the memory function*
c::> page 62.
- If there should be a malfunction in the
electrical system, you can still adjust the
exterior mirrors by pressing the edge of
the mirror.

on them, for example from headlights on a
vehicle to the rear.
A WARNING -
Electrolyte fluid can leak from automatic
dimming mirrors if the glass is broken. Electrolyte fluid can irritate skin, eyes and
respiratory system .
- Repeated or prolonged exposure to elec­
trolyte can cause irritation to the respira­
tory system, especially among people
with asthma or other respiratory condi ­
tions. Get fresh a ir immediately by leav­
ing the vehicle or, if that is not possible,
open windows and doors all the way.

Operation
We recommend pressing the IAUTO I button and setting the temperature to 72 °F (22 °C).

Press the buttons to turn the functions on or
off. Use the d ials to adjust the temperature,
the blower speed and the a ir distribution. The
L ED in a button will light up when the func­
tion is switched on. The settings are displayed
for a few seconds in the radio or MMI* display.
In vehicles with a 3-zone deluxe automat ic cl i­
mate control systems *, the dr iver and front
passenger side can be adjusted separately.
The settings are also d isplayed in the climate
con trol system display.
IOFFI Switching the climate control
system on/off
The IOF FI button switches the climate control
sys tem on or off.
It also switches on when you press the knob. Airflow from outs
ide is
blocked when the climate control system is
switched off.
IACI Switching cooling mode on/off
The air is not coo led and humidity is not re­
moved when cooling mode is switched off.
This can cause fog on the w indows. Cooling
mode switches off automatically when the
outside temperature is be low zero.
1- 1 Switching recirculation mode on/off
In recircu lation mode, the air inside the vehi ­
cle is circulated and filtered. This prevents the
unfiltered air outside the vehicle from enter­
ing the vehicle interior. We recommend

192 Intelligent technology
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is d ischarged by idling current consumers
(e.g. immobilizer). In ce rtain circumstances it
can result i n there bei ng insuff ic ient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d ist ribu tion of elect rical ener­
gy. Starting ab ility is mar ked ly imp roved and
the life of the battery is extended .
Basically , energy management consists of
batt ery diagno sis , idling curr ent manag e­
ment
a nd dynami c energy man agement .
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature . This dete rm ines the current
sta te of charge and the power of the ba ttery.
Idling current management
Idling current management reduces energy
consumption wh ile the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
ene rgy s upply to the va rio us e lectrica l compo­
nents . Data from battery diagnosis is consid­
e red.
Depending on the battery's state of charge,
i nd ividua l consumers are grad ually t urned off
to p revent ex cess ive d isc harge of the ba ttery
and thus mainta in start ing capability.
Dynamic energy management
While the vehicle is be ing dr iven , dynamic en­
e rgy management dist ributes t he energy gen­
e rated accordi ng to the needs of the individu­
a l componen ts.
It reg ulates consump tion, so
that more electrical ene rgy is not being used than
is being generated and ensures an opti ­
mal state of charge for the battery.
(D Tips
- But even energy man ageme nt canno t
negate the limi ts of physics . Conside r
that the powe r and life of a battery are
limited .
- If start ing ability is threatened, the indi ­
cator light (•) appears ~
page 17.
What you should know
The highest priority is given to maintaining
starting capability .
The b attery is severe ly taxed in short -d istance
driv ing, in ci ty traff ic and during t he cold time
of yea r. Ab undant electrical energy is re­
quired, but on ly a little is generated . It is also
critical if the engine is not r unning and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being generated .
It is in precisely these s ituations that you will
notice energy management active ly reg ulat­
ing the d istribution of energy.
Vehicle stand s for an e xtended period
If you do not drive your vehicle over a period
of several days or weeks, e lectrica l compo ­
nents are gradually cut back or sw itched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer pe riod .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustme nt. The convenience
f unc tions wi ll be available again when yo u
swi tch on the igni tion and sta rt the eng ine .
With the engine turned off
If you listen to the radio, for examp le, w it h
the engine t urned off or use other MMI func­
t ions, t he battery is be ing discharged.
If starting capability is jeopardized due to en ­
ergy consump tion, the following warning ap-
pears in the MM I display: .,,.
