Chevrolet TrailBlazer 2002-2009  Engine Oil Life Reset Guide

The TrailBlazer and its twin, the GMC Envoy, trail the competitors because of sloppy handling, ill-fitting trim, hard-to-reach front safety belts, and excessive wind noise. Off-roading is not a strength, but the low-speed ride is absorbent. The SS model has a 390-hp, 6.0-liter V8. In our testing, the six-cylinder sounded strained and returned only 15 mpg. Stability control is standard, making emergency handling secure. Crash-test results are unimpressive. Curtain air bags are standard. Reliability has been average. but the TrailBlazer scores too low to be recommended. General Motors has ended production of the TrailBlazer, GMC Envoy, and Saab 9-7X.

How to Reset the Engine Oil Life System

The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a change engine oil light or CHANGE ENGINE OIL message being turned on, reset the system. 

To reset the Engine Oil Life System: 

1. Turn the ignition key to ON/RUN with the engine off. 

2. Fully press and release the accelerator pedal slowly three times within five seconds. The change engine oil light will flash while the system is resetting. 

3. When the light stops flashing, turn the key to LOCK/OFF. 

If the light/message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure.
