STARTING AND DRIVING

Battery drain

Your vehicle's electrical functions drain the bat-
tery to varying extents.
Avoid using ignition mode II as much as posssi-
ble, or electrical functions that require a great
deal of electrical current when the engine is not
running.
Using ignition mode I whenever possible con-
sumes less electrical current.
Functions that require a great deal of electrical
current include:
•
the climate system blower
•
headlights
•
wipers
•
infotainment system (especially at high vol-
ume).
If the battery's charge level is low, a text message
will appear in the instrument panel. The vehicle's
energy-saving function will then turn off or
reduce certain functions that are currently con-
suming electrical current.
If the battery needs to be recharged, start the
engine and let it idle for at least 15 minutes or
drive the vehicle (driving charges the battery
faster than letting the engine idle).
