How to Reset a Service Light on a 2006 Jeep Grand Cherokee Laredo

by Katebo

The 2006 Jeep Grand Cherokee is equipped with sensors and computer hardware that monitor engine performance and cause a "Service Engine" light to illuminate on the Grand Cherokee's instrument panel when the sensors detect a failure in the emissions system. Another reason the light might illuminate is because the odometer has reached a preset mileage interval that coincides with the manufacturer's recommended routine services such as an oil change or a tuneup, regardless of how often you perform regular maintenance on the Grand Cherokee. When you take your Grand Cherokee to the dealer service department or to another qualified mechanic, after the mechanic performs the service, he will usually reset the light to turn it off. If the light is still on after the servicing or if you perform the service yourself, you will need to manually reset the light. Make sure you do it right after the Grand Cherokee is serviced to ensure that the computer will keep proper track of the next service interval.

Step 1

Put the Grand Cherokee's ignition key into the ignition and turn it to "Run." Don't start the engine.

Step 2

Locate the "Step" button on the Grand Cherokee's instrument panel and press it. Press it again until it says "Miles to Service."

Press in and hold the button for about five seconds. It should read "Reset." This will turn off the service light on the display.
