If the switch is in the center position, the inte
rior l ights turn on automatically when you un
lock the vehicle, open a door or remove the ig
n ition key. The interior lights turn off several
seconds after your close the doors , when you
lock the vehicle or when you turn the ign it ion
on. When a door is open, the light tu rns off
after a few minutes.

Instrument illumination
The basic brightness of the illumination for
the instruments, the center console and the
display can be adjusted .

nal posit ion.
(!') Tips
The instrument illumination (for dials and
needles) lights on when the ignition is
switc hed on and the vehicle lights are
turned off. As the daylight fades, the illu
mination of the dia ls likewise dims auto
matically and wi ll go out completely when
the ou tside light is very low. This feature is
meant to rem ind yo u to sw itch on the
headlights when ou tside light conditions
become poo r.

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
i s not driven for a long period of time, the bat
tery is discharged by idling current consumers
(e.g. immobilizer) . In certain circumstances it
can result in there being insufficient energy
avai lab le to start the engine.
I ntelligen t energy management in your vehi
cle handles the distribution of electrical ener
gy . Starting ability is marked ly improved and
the life of the battery is extended .
Basically, energy management consists o f
battery diagnosis, idling current manage
ment
and dynamic energy management.
Battery diagnosis
Batt ery d iagnosis continuously dete rmines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo
nents . Data from battery diagnosis is consid
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus mainta in start ing capability.
Intelligent technology 191
Dynamic energy management
While the vehicle is being driven, dynamic en
ergy management distrib utes the energy gen
erated according to the needs of the individ u
al components. It regulates consumption, so
that more e lectrical energy is not being used
than is being generated and ensures an opti
mal state of charge fo r the battery .
{!) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power 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 battery is severe ly taxed in short-distance
driv ing, in city traff ic and during the cold time
of year. Abundant electrical energy is re
quired, but on ly a little is generated . It is also
c rit ical if the engine is not running 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 situations that you will
notice energy management actively regulat
in g the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electr ical compo
nents are gradually cut back or switched off .
T h is reduces energy consumption and main
tains starting 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
functions will be available again when you
switch on the ignition and start the engine.

264 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!
Fig. 195 Engine compartment: Connecto rs fo r jum per
cables and charger
Fig. 196 Jump sta rting wi th the battery of anot her ve ·
h ide :@ booster battery, @ disc harged vehicle battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your vehicle .
Vehicle with discharged battery:
.. Turn off lights and accessories, move lever
of automatic transmission to N (Neutral) or
P (Park) and set parking brake .
Connect POSITIVE(+) to POSITIVE(+)
(red)
.. Remove the cover above the jump start con
nection .
.. Open the red
cover on the positive pole
¢fig. 195.
1. Connect one end of the red positive cable
on the
jump start bolt c::> fig. 196 @
(Bolts under red cover= "positive") of the
vehicle to be started @.
2. Connect the other end to the positive ter-
mina l@ of the booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Connect one end of the b lack negative ca
ble to the negative terminal @of the
booster battery @.
4. Connect the other end to the
jump start
bolt @
(Bolts with hex head= "negative")
of the vehicle to be started ®·
Starting the engine
.. Sta rt the engine of the vehicle with the
booster battery@. Run the engine at a
moderate speed.
.. Start engine with discharged vehicle battery
® in the usual manner .
.. If the eng ine fails to start: do not keep the
starter cranking for longer than 10 seconds .
Wait for about 30 seconds and then try
again .
.. With engine running, remove jumper cables
from both vehicles in the exact
reverse or
der .
.. Close the red
cover on the positive pole .
T he battery is vented to the outside to prevent
gases from entering the vehicle interior . Make
sure that the jumper clamps are well connect
ed with their
metal parts in full contact with
the battery terminals.
A WARNING
--
To avoid serious personal injury and dam
age to the veh icle, heed all warnings and
i nstructions of the jumper cable manufac-
turer . If in doubt, call for road service . ..,.
