Lighting Features
Entry Lighting
Some exterior lamps and the interiorlamps turn on briefly at night, or in
areas with limited lighting, whenK
is pressed on the Remote KeylessEntry (RKE) transmitter. When adoor is opened, the interior lampscome on if the dome lamp control isin the DOOR position. After about30 seconds the exterior lamps turnoff. Entry lighting can be disabledmanually by changing the ignitionout of the OFF position, or by
pressing the RKE transmitterQ
button.
This feature can be changed. See“Ve h i c l e L o c a t o r L i g h t s”underVehicle Personalization0160.
Exit Lighting
Some exterior lamps and the interiorlamps come on at night, or in areaswith limited lighting when the key isremoved from the ignition. Theexterior and interior lamps remainon for a set amount of time and then
automatically turn off. The interiorlamps do not come on if the domelamp control is in the Off position.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0160.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage
moving up or down. This is normal.If there is a problem, an alert will bedisplayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.
