How to Reset the Oil Life on a GMC Sierra 1500

1. Bring up the oil life percentage on the Driver Information Center (DIC).
2. Press and hold the thumbwheel on the steering wheel for several seconds.
3. If the vehicle has no DIC controls, press and hold the trip odometer reset stem instead.
4. When the confirmation message appears, select YES.
5. Check that the oil life now reads 100%.

• Reset only right after an oil change; the system will not reset itself.
• If the system is reset by accident, change the oil within 5 000 km (3,000 mi) of the last change.
