Lighting Features
Some exterior lamps and the interior lamps turn on briefly at night, or in areas with limited lighting, when K is pressed on the Remote Keyless Entry (RKE) transmitter. When a door is opened, the interior lamps come on if the dome lamp control is in the H position. After about
30 seconds the exterior lamps turn off. Entry lighting can be disabled manually by changing the ignition out of the OFF position, or by pressing Q on the RKE transmitter.
This feature can be changed. See“Vehicle Locator Lights” under Vehicle Personalization 0 120.
Some exterior lamps and the interior lamps come on at night, or in areas with limited lighting when the key is removed from the ignition. The exterior and interior lamps remain on for a set amount of time and then
automatically turn off. The interior lamps do not come on if the dome lamp control is in the Off position.
The exterior lamps turn off immediately by turning the exterior lamps control off.
This feature can be changed. See
Vehicle Personalization 0 120.
The vehicle has Electric Power Management (EPM), which estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery.
When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. The voltmeter gauge or the voltage display on the Driver Information Center (DIC),
if equipped, may show the voltage
moving up or down. This is normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.
A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.
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.
This feature shuts off the dome and reading lamps, if they are left on for more than 10 minutes after the ignition is turned off. The cargo lamp shuts off after 20 minutes. This prevents the battery from
running down.
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 O position and then back to the ; or 2 position.
To keep the lamps on for more than 10 minutes, the ignition must be on or in ACC/ACCESSORY.
