Fluid and Lubricant Recommendations
| Usage | Fluid/Lubricant |
|---|---|
| Engine Oil | The engine requires engine oil approved to the dexos™ specification. Oils meeting this specification can be identified with the dexos™ certification mark. Look for and use only an engine oil that displays the dexos™ certification mark of the proper viscosity grade. SAE 5W-30 GM P/N 19293000 (Canadian P/N 19286321) is the best viscosity grade for the vehicle. Do not use other viscosity oils such as SAE 10W-30, 10W-40, or 20W-50. |
| Engine Coolant | 50/50 mixture of clean, drinkable water and use only DEX-COOL Coolant GM P/N 12346290 (Canadian P/N 10953464). |
| Hydraulic Brake System | DOT 3 Hydraulic Brake Fluid GM P/N 12377967 (Canadian P/N 89021320) |
| Windshield Washer | Automotive windshield washer fluid that meets regional freeze protection requirements. |
| Power Steering System | GM Power Steering Fluid GM P/N 89021184 (Canadian P/N 89021186) |
| Automatic Transmission - 4L60-E/4L65-E/4L70-E | DEXRON®-VI GM P/N 88861003 (Canadian P/N 88861004) |
| Key Lock Cylinders | Multi-Purpose Lubricant, Superlube GM P/N 12346241 (Canadian P/N 10953474) |
| Chassis Lubrication | Chassis Lubricant GM P/N 12377985 (Canadian P/N 88901242) or lubricant meeting requirements of NLGI #2, Category LB or GC-LB |
| Transfer Case | DEXRON®-VI GM P/N 88861003 (Canadian P/N 88861004) |
| One-Piece Propshaft Slip Yoke Spline, Two-Piece Propshaft Slip-in-Tube Spline | Spline Lubricant, Special Lubricant GM P/N 19257121 (Canadian P/N 19257122) |
| Hood Hinges | Multi-Purpose Lubricant, Superlube GM P/N 12346241 (Canadian P/N 10953474) |
| Weatherstrip Conditioning | Weatherstrip Lubricant GM P/N 3634770 (Canadian P/N 10953518) or Dielectric Silicone Grease GM P/N 12345579 (Canadian P/N 10953481) |

GM Oil Life System Resetting
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A ENGINE OIL light message will come on. Change the engine oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset.
If the system is ever reset accidentally, change the engine oil at 3, 000 miles (5 000 km) since last oil change.
How to Reset the Engine Oil Life System
- Turn the ignition key to ON/RUN with the engine OFF.
- Fully press and release the accelerator pedal slowly three times within five seconds.
- Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comes back on when you start the vehicle, the ENGINE OIL LIFE SYSTEM has not reset. Repeat the procedure.
