Lighting Setup Instructions
Battery Load Management
The vehicle has an Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended battery life. 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. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move 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 of the power needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as headlamps, high beams, 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 battery voltage and charging message are displayed. It is recommended that the driver reduce the electrical loads as much as possible.
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 doors are closed and then re-opened.

Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes after the vehicle 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 vehicle must be on or in accessory mode.
FAQ’s
The dome lamps are typically controlled through the interior lighting settings on the dashboard.
Reading lamps are designed for focused illumination, often positioned near seats for reading. They are a specific type of interior lighting, distinct from the broader coverage of dome lamps.
The colour of the dome lamps is typically fixed, but certain models may offer customizable options.
The duration varies but is generally set to a short period, such as a few seconds or minutes, to provide adequate lighting for exiting the vehicle.
