Battery Power Protection
This feature helps prevent the battery from being drained, if the interior courtesy lamps or reading lamps are accidentally left on.
If any of these lamps are left on, they automatically turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until one of the following occurs:
• The ignition is turned on.
• The exterior lamps control is turned off, then on again.
The headlamps will time out after 10 minutes, if they are manually turned on while the ignition is on or off.
