Fluids

Proper fluid levels and approved fluids protect the vehicle’s systems and components. See Recommended Fluids and Lubricants on page 11‑12 for GM approved fluids.

• Engine oil and windshield washer fluid levels should be checked at every fuel fill.

• Instrument cluster lights may come on to indicate that fluids may be low and need to be filled.
