06 Starting and driving
General
Do not overload the battery
The electrical functions in the car load the
battery to varying degrees. Avoid using the
ignition position II when the engine is
switched off. Use ignition position I instead,
as less power is consumed.
Examples of functions that use a lot of
power:
• ventilation fan
• windscreen wipers
• audio equipment (high volume)
• parking lights
Also, be aware of different accessories that
load the electrical system. Do not use func-
tions which use a lot of power when the
engine is switched off.
If the battery voltage is low, a message
06
appears on the display. The energy-saving
function shuts down certain functions or
reduces the load on the battery by, for exam-
ple, slowing the ventilation fan and switching
off the audio equipment. Charge the battery
by starting the engine.
