functions , the luggage compartment lid can be
opened at the lock cylinder .

_&. WARNING
-After closing the luggage compartment lid,
make sure that it is latched. The luggage
compartment lid could otherwise open s ud­
denly whi le driving, even if the lock cylinder
is closed. This would increase the risk of an
acc ident.
- Never drive with the luggage compartment
lid ajar or open, because poisonous gases
can enter the vehicle interior and create the
risk of asphyxiation .

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.

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.
