Black plate (9,1)Cadillac SRX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-7707476) - 2015 - crc - 4/8/14Lighting 6-9When 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. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.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 of thepower needed for very highelectrical loads.A high electrical load occurs whenseveral 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.Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a DIC message mightbe displayed and it is recommendedthat the driver reduce the electricalloads as much as possible. SeeBattery Voltage and ChargingMessages on page 5-28.Battery Power ProtectionThe battery saver feature isdesigned to protect the vehicle'sbattery.If some interior lamps are left onand the ignition is turned off, thebattery rundown protection systemautomatically turns the lamp off aftersome time.Exterior Lighting BatterySaverThe exterior lamps turn off about10 minutes after the ignition isturned off, if the parking lamps orheadlamps have been manually lefton. This protects against drainingthe battery. To restart the 10-minutetimer, turn the exterior lamp controlto the off position and then back tothe parking lamp or headlampposition.To keep the lamps on for more than10 minutes, the ignition must be inthe ACC/ACCESSORY or ON/RUNposition.InformationProvidedby:
