GMC Exterior Lighting
Exterior Lamp Controls
The exterior lamp control is on the turn signal lever.
Turn the control to the following positions:
: Turns off the exterior lamps and deactivates AUTO mode. The knob returns to the AUTO position after it is released. Turn to
again to reactivate AUTO mode. For vehicles first sold in Canada, the headlamps will automatically reactivate when the vehicle is shifted out of P (Park).
AUTO: Automatically turns the exterior lamps on and off, depending on outside lighting.
: Turns on all lamps, except the headlamps.
: Turns on the headlamps, parking lamps, and instrument panel lights.
IntelliBeam System
This system turns the high-beam headlamps on and off according to surrounding traffic conditions.
The system turns the high-beam headlamps on when it is dark enough and there is no other traffic present.
This light 
appears in the instrument cluster when the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam
To enable the IntelliBeam system, press the button on the end of the turn signal lever when the exterior lamp control is in the AUTO or position.
Driving with IntelliBeam
The system only activates the high beams when driving over 40 km/h (25 mph). The blue high-beam light appears on the instrument cluster when the high beams are on.
There is a sensor near the top centre of the windshield that automatically controls the system. Keep this area of the windshield clear of debris to allow for the best system performance.
The high-beam headlamps remain on, under automatic control, until one of the following situations occurs:
- The system detects an approaching vehicle’s headlamps.
- The system detects a preceding vehicle’s taillamps.
- The outside light is bright enough that high-beam headlamps are not required.
- The vehicle speed drops below 20 km/h (12 mph).
The IntelliBeam system is disabled by the button on the turn signal lever. If this happens, press the button on the end of the turn signal lever when the exterior lamp control is in the AUTO or
position. The instrument cluster light will come on to indicate the IntelliBeam system is reactivated.
The high beams may not turn off automatically if the system cannot detect another vehicle’s lamps because of any of the following:
- The other vehicle’s lamps are missing, damaged, obstructed from view, or otherwise undetected.
- The other vehicle’s lamps are covered with dirt, snow, and/or road spray.
- The other vehicle’s lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
- The windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
- The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
- The vehicle is being driven on winding or hilly roads.
The automatic high-beam headlamps may need to be disabled if any of the above conditions exist.
Exterior Lamps Off Reminder
A warning chime sounds if the driver’s door is opened while the vehicle is off and the exterior lamps are on.
Headlamp High/Low-Beam Changer

Daytime Running Lamps (DRL)
DRL can make it easier for others to see the front of your vehicle during the day.
Fully functional DRLs are required on all vehicles first sold in Canada.
The DRL come on when all of the following conditions are met:
- The vehicle is on.
- The exterior lamp control is in AUTO.
- The light sensor determines it is daytime.
The taillamps, instrument panel lights, and other lamps will not turn on when this feature is activated.
The DRL turns off when the headlamps are turned to or the vehicle is off.
For vehicles first sold in Canada, the DRL can only be turned off when the vehicle is parked.
Automatic Headlamp System
When the exterior lamp control is set to AUTO and it is dark enough outside, the headlamps come on automatically.
There is a light sensor on top of the instrument panel. Do not cover the sensor.
The system may also turn on the headlamps when driving through a parking garage or tunnel.
If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. If it is light outside when the vehicle leaves the garage, there is a slight delay before the automatic headlamp system changes to the Daytime Running
Lamps (DRL). During that delay, the instrument cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position.
When it is bright enough outside, the headlamps will turn off or may change to DRL.
The automatic headlamp system turns off when the exterior lamp control is turned on
or the vehicle is off.
Lights On with Wipers
If the windshield wipers are activated in daylight with the vehicle on, and the exterior lamp control is in AUTO, the headlamps, parking lamps, and other exterior lamps come on. The transition time for the lamps coming on varies based on the wiper speed. When the wipers are not operating, these lamps turn off. Move the exterior lamp control to

The lever returns to its starting position when it is released.
If after signalling a turn or lane change, the arrow flashes rapidly or does not come on, a signal LED may be burned out

Exit Lighting

The exterior and interior lamps remain on for a set amount of time, and then automatically turn off.
The interior lights turn on when the vehicle is turned off.
The exterior lamps turn off immediately by turning the exterior lamp control off.
This feature can be changed. On the infotainment home screen, select Settings > Vehicle > Exit Lighting.
Battery Load Management
The vehicle has an Electric Power Management (EPM) that estimates the battery temperature and state of charge. It then adjusts the voltage for best performance and extended life of the 12-volt battery.
When the battery state of charge is low, the voltage is raised slightly to quickly increase the charge. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. As this adjustment occurs, you may see the voltage move up or down on the voltmeter gauge or voltage display on the Driver Information Center (DIC), if equipped. This is normal. If a problem occurs, an alert will be displayed.
If the electrical loads are very high, the battery can be discharged when the vehicle is stationary. A high electrical load occurs when several features are on, such as: headlamps, high beams, rear window defogger, climate control fan at high speed, heated seats, motor cooling fans, trailer loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery by balancing the electrical system output and the vehicle’s electrical needs. In some cases, it can temporarily reduce the power demands of some accessories.
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 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 when the vehicle is turned off. The lamps will not come back on again until one of the following occurs:
- The vehicle is started.
- 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
position and then back to the
position.
To keep the lamps on for more than 10 minutes, the vehicle must be on.
