Exterior Lights
If the manual light control is left on
when the ignition is turned off, the
exterior lights will turn off
automatically after 10 minutes to
keep your battery from draining.
If the lights were left on
intentionally, turn the manual
light control off then back on to
reactivate the exterior lights.
If the manual light control is
turned on after the ignition is
turned to the OFF position, the
exterior lights will not
automatically turn off.
■ ELECTRIC POWER
MANAGEMENT
This system monitors the tempera-
ture and charge status of the vehi-
cle's battery and automatically
adjusts the voltage to enhance
performance and extend battery
life.
You may see the battery voltage
reading fluctuate in the Driver
Information Center display. This is
normal.
If the system senses a problem, a
message will appear on the Driver
Information Center display.
See "Driver Information Center
Messages" earlier in this section for
more information.
