Considering it’s made by a GM company, I would assume the standard practice here works there…
Turn key to on, but do not start…
Pump gas peddle three times…
Press and hold brake peddle till the service light blinks and then goes out…
Start the car to make sure the light was reset…
Or…
Turn to on…
Hold trip reset button…
Start car
keep holding trip reset till the light on the dash goes out…
Hopefully one of those works, but they’re just kinda the ‘try this’ until someone who knows chimes in.
