The grille on the controls <=> fig. 94 must
remain unobstructed and must not be tap­

Turning the climate control system on and off
Applies to vehicles: with deluxe automatic climate co ntrol
.. Briefly press the IOFFI button, or press the
IAUTOI button to turn the climate control
system
on .
.. Press the ~ ,o~ F=F ~I button to turn the climate
control system off and to block the a ir sup­
ply from the outside.
The climate control system switches back on
when a control button is operated.
Automatic mode~
Applies to vehicles: with deluxe automatic cl imate control
The standard operating mode for all times of
the year.
Tu rning on au tomatic mode
.. Set the temperature between 60° F (+16°()
and 84°F (+28°() .
.. Press the
!AUTO l button.
Automatic mode ensures constant tempe ra ­
tures in the interior and dehumidifies the air
ins ide the veh icle. Air temperat ure, volume
and d istribution are controlled automatically
to reach or maintain the desired inter ior tem­
perature as quickly as possible . Fluctuations
i n exte rior temperature and the effects of
temperature from the pos ition of the sun are
compensated fo r automat ically.
W arm and cold 81
This operating mode wo rks on ly in an adjusta ­
ble temperature range of 60°F (+16°() to
84°F (+28°(). If a temperature be low 60°F
( + 16°() is selected,
LO appears in the disp lay.
At temperatures above 84°F (+28°(),
HI is
displayed . At both extreme settings, climate
control runs co ntinuously at maximum cool­
ing o r heating powe r. The re is no temperature
r egulation.
Setting the temperature
Applies to vehicles: with deluxe automatic climate control
Fig. 95 Tempe rat ure sett ing regula tor
.. Rotate the regulator to the left to reduce
the temperature, or to the right to i ncrease
the temperature<=>
fig. 95 .
The selected temperature appears on the cl i­
mate control display. The temperature setting
will also appear for a few seconds in the radio
or MM I* display .

Applies to vehicles: with deluxe a utomatic clima te control
The automatically preset fan speed can be re­
duced or increased .

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 discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
batt ery di ag nosis, idlin g current man ag e­
m ent
and dyn ami c en ergy manage ment .
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determ ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces ene rgy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy supply to the va rious electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the bat tery
and thus maintain starting capability .
Dynam ic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 211
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
negate the limits of physics . Consider
that the power and life of a battery are
limited .
- If starting ability is threatened, you are
informed by a warning
r:!) page 212,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -distance
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­ quired, but only a little is generated .
It is also
critical if the engine is not running and electri­
cal components are turned on . In this in­
stance energy is be ing consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat ­
ing the d istribution of energy .
Vehicle stands for an e xtended peri od
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in ­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the power seat adjustment . The convenience
funct ions w ill be available again when you
tu rn o n the ign ition and start the engine.
With the eng ine tu rned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func -
tions, the battery is be ing discharged.
