STARTING AND DRIVING
Battery drain
The electrical functions in the vehicle drain
the battery to varying degrees. Avoid using
ignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current
when the engine is turned off. Examples of
such functions are:
blower
•
headlights
•
windshield wipers
•
audio system (especially at high volume).
•
If the starter battery voltage is low, a message
is shown in the driver display. The vehicle's
energy-saving function will then turn off or
reduce certain functions, such as the blower
and/or the audio system.
Charge the battery by starting the engine
–
and let it run for at least 15 minutes (driv-
ing charges the battery faster than letting
the engine idle).
