WARNING
When extending or retracting the rear spoiler,
please make sure that no persons or objects
are close to the moving spoiler - risk of injury!
CD
CAUTION
- If you need to push the vehicle, never put
your weight on the rear spoiler - Risk of
damage!
- To avoid damage to the rear spoiler, you
should not lean on it or apply any other type
of pressure.
- Do not operate the rear spoiler manually
when the boot lid is open or any moving
parts of the automatic rear spoiler are ob
structed - risk of damage!
Note
Clean the rear spoiler housing every 2 to 3
months. The rear spoiler housing must be
free of ice, snow and leaves in order to oper
ate correctly.
Power management
This system helps to ensure reliable
starting
The power management controls the distribu
tion of electrical energy and thus helps to ensure
that there is always enough power available to
start the engine.
If a vehicle with a conventional electrical system
is left parked for a long time, the vehicle battery
will gradually lose its charge because certain
electrical equipment (such as the immobiliser)
continues to draw current even when the ignition
is off. In some cases there may not be enough
power available to start the engine.
Your vehicle is equipped with an intelligent pow
er management system to control the distribu
tion of electrical energy. This significantly im
proves reliability when starting the engine, and
also prolongs the life of the vehicle battery.
The main functions incorporated in the power
management system are
battery diagnosis, re-

sidual current management
and
dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis
ters the condition of the vehicle battery. Sensors
detect the battery voltage, battery current and
battery temperature. This enables the system to
calculate the current power level and charge con
dition of the vehicle battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It con
trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power level of the vehicle bat
tery, the individual electrical components are
switched off one after the other to prevent the
vehicle battery from losing too much charge and
to ensure that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function distrib
utes the available power to the various electrical
components and systems according to their re
quirements. It ensures that on-board systems do
not consume more electrical power than is being
generated, and thus maintains the maximum
possible vehicle battery power level.

- The power management system is not able
to overcome the given physical limits.
Please remember that the power and life of
the vehicle battery are limited.

Points to remember
Starting ability has first priority.
Short trips, city traffic and low temperatures all
place a heavy load on the vehicle battery. In
these conditions a large amount of power is
