(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the vehicle batte ry life are
limited.
- When the starting ability is endangered, the
(•j indicator light turns on ¢ page 14.
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on t he 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 a lso critical
when the engine is not running but e lectr ical
equ ipment is switched on. In th is case, energy is
used but none is generated .
In s ituations like this, energy management will
actively regu late the distribution of ene rgy.
Long periods without use
If you do not drive you r vehicle for several days or
weeks, e lectrica l equipment is gradually sca led
back or switched off. This reduces energy use and
ens ures the veh icle w ill 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
ava ilable again once you switch the ignition on
an d sta rt the engi ne.
With the engine switched off
The vehicle battery will drain if you use Infota in-
ment functions such as listening to the rad io
while the eng ine is switched off .
The vehicle's ability to start may be impaired by
the energy use, a message will appear in the In-
fotainment system d isplay .
The message ind icates that the system will
switch off automatically soon. If you wou ld like
Intellig e nt Technology
to cont inu e using the functions, you must start
t he engine.
With the engine running
Alt hough e lectr ica l energy is ge nerated wh ile
dr iving , the ve hicle ba tt ery can dra in. This ca n
happen if lit t le ene rgy is generate d but much is
used , and t he charge level of the vehicle battery
is not optimal.
To rest ore the balance of ene rgy, componen t s
t hat require large a moun t s of ene rgy are t empo -
rarily scaled back or switched off . Heat ing sys-
tems in partic ular req uire a great dea l of energy .
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
These systems are availab le aga in as soo n as the
energy sup ply has bee n restored .
In add ition, you may notice that the idle speed
has slig htly increased. That is normal and no
cause for concern . By increas ing the idling speed,
the addit ional required energy will be generated
and the vehicle battery will be charged .
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equ ipped w ith an Event Data Re-
corder (EDR). The ma in purpose of a n EDR is t o
record, in certai n cras h or nea r crash-like situa-
ti o ns, such as an airbag deployme nt or hittin g a
road obsta cle, da t a t hat will ass ist in underst a nd-
ing how a vehicle 's systems performed . The EDR
is des igned to record data related to vehicle dy-
namics and safety systems for a short perio d of
t ime, typ ically 30 seconds or less . The EDR in this
vehicle is designed to record such data as:
- How various systems in your vehicle were ope r-
ating;
- W het her or not t he drive r and passenge r safety
be lts were buckled/fastened;
- How far (if at a ll) the d river was dep ressing the
accelerator and/or bra ke pedal; and, .,,.
