EPM works to prevent excessive
discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs.
It can increase engine idle speed to generate more power whenever
needed. It can temporarily reduce the power demands of some accessories.
Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the driver. If so, a DIC message might be displayed and it is recommended that the driver reduce the electrical loads as much as
possible.
Battery Power Protection
The battery saver feature is designed to protect the vehicle's battery.
If some interior lamps are left on and the ignition is turned off, the battery rundown protection system
automatically turns the lamp off after some time.
Exterior Lighting Battery Saver
The exterior lamps turn off about
10 minutes after the ignition is turned off, if the parking lamps or headlamps have been manually left on. This
protects against draining the battery. To restart the 10-minute timer, turn the exterior lamp control to the off
position and then back to the parking lamp or headlamp position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in ACC/ACCESSORY.
