alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in
stop-and-go traffic. This precaution helps to avoid
draining of the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.
