2022 Chevrolet Silverado 1500 Lighting Features
Lighting Features
Entry Lighting
- The interior lamps turn on when pressing
on the remote key or opening any doors, and the dome lamp control is in the DOOR position. - Some exterior lamps also turn on when pressing on the remote key or opening any doors. Low-Beam lamps will only turn on briefly at night, or in areas with limited lighting.
- All lamps will gradually fade out after about 30 seconds.
- Entry lighting can be disabled manually by closing all doors, pressing
on the remote key, or starting the vehicle. - This feature can be changed. See “Vehicle Locator Lights” under Vehicle Personalization 132.
Exit Lighting
- Some exterior lamps come on at night, or in areas with limited lighting, when the driver’s door is opened after the ignition is turned off.
- The dome lamp comes on when any door is opened or after the ignition is turned off.
- The exterior lamps and dome lamps remain on after the door is closed for a set amount of time, then automatically turn off.
- The exterior lamps turn off immediately by turning the exterior lamp control off. The exit lighting for exterior lights can be changed. See Vehicle Personalization 132.
Battery Load Management
- The vehicle has Electric Power Management (EPM), which estimates the battery’s temperature and state of charge. It then adjusts the voltage for the 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.
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 cargo lamp shuts off after 20 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 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
position and then back to the 
or 
positions. - To keep the lamps on for more than 10 minutes, the ignition must be on or in ACC/ACCESSORY.
