Chevrolet Silverado: Vehicle Checks / Engine Oil Life System

Chevrolet Silverado 2019-2024 Owners Manual / Vehicle Care / Vehicle Checks / Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.

On some vehicles, when the system has calculated that oil life has been diminished, a CHANGE ENGINE OIL SOON message comes on to indicate that an oil change is necessary. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. For vehicles without the CHANGE ENGINE OIL SOON message, an oil change is needed when the REMAINING OIL LIFE percentage is near 0%. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.

If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change.

Remember to reset the oil life system whenever the oil is changed.

How to Reset the Engine Oil Life System

Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the engine oil life system:

  1. Display the oil life percentage on the DIC. See Driver Information Center (DIC) (Base Level) or Driver Information Center (DIC) (Midlevel and Uplevel).
  2. Press the thumbwheel on the steering wheel, or the trip odometer reset stem if the vehicle does not have DIC controls, for several seconds. When the confirmation message displays, select YES. The oil life will change to 100%.

The oil life system can also be reset as follows:

  1. Display the oil life percentage on the DIC. See Driver Information Center (DIC) (Base Level) or Driver Information Center (DIC) (Midlevel and Uplevel).
  2. Fully press the accelerator pedal slowly three times within five seconds.
  3. If the display changes to 100%, the system is reset.

If the vehicle has a CHANGE ENGINE OIL SOON message and it comes back on when the vehicle is started and/or the oil life percentage is near 0%, the engine oil life system has not been reset. Repeat the procedure.

    Blind Spot Mirrors

    If equipped, there is a small convex mirror built into the upper and outer corner of the driver outside mirror. It can show objects that may be in the vehicle's blind zone.

    Driving with the Blind Spot Mirror

    Actual Mirror View

    When the approaching vehicle is a long distance away, the image in the main mirror is small and near the inboard edge of the mirror. As the vehicle gets closer, the image in the main mirror gets larger and moves outboard. As the vehicle enters the blind zone, the image transitions from the main mirror to the blind spot mirror. When the vehicle is in the blind zone, the image only appears in the blind spot mirror.
