I have changed the lube oil and filter in my mountainer, but the display on the dashboard still shows 'oil change required'. How do I the 'oil change required' message?

The 04 was pretty straight forward.

Change the oil and filter when the display tells you to. (Don't forget to reset Oil Life system!)
when the display tells you to change engine oil... Do the following as well:
~Lube Chassis Components
~Check Tires for Air and Damage
~Inspect Break System
~Check Engine Fluids and Washer System
~Check Power Steering System
~Check Wiper Blades
~Check Restraint System
~Lube Body Components (See manual)
~Replace Cabin Air Filter (Located in firewall on passenger side.)


Every 25K miles do the following:
~ Inspect Fuel System, Exhaust System, Accessory Drive Belts for damage or wear.
~ Replace Air Cleaner

Ever 50K Miles
~ If used for Towing - Replace Transfer Case Fluid :: If not change fluid ever 75Kk miles.

Every 100k Miles
~ Change Automatic Transmission Fluid and Filter
~ Change Automatic Transmission Fluid and Filter again at 150k if heavy service
~ Replace Spark Plugs

Every 150k miles
~ Change Engine Coolant (Or every 5 years which ever comes first!)
~ Replace Engine Accessory Drive Belt

optional y are supposed to change the transfer case fluid every 50k if towing

Usually you want to change the oil every 3,000-5,000 miles. Have the lower ball joints and outer tierod ends, if they have grease fittings.

Check youtube someone may have already made a video on how to re set it.

Good luck and keep me posted and i'll try to explain again in a different way. Harder to tell then to show how to do it. 

maybe just try unhooking and waiting 10 min then rehooking up the battery . maybe get lucky :)

Hi,
Hold the reset button in for 5 seconds.

You should then get a message the the "oil" life is 100% or the oil change required light will go out.
I hope this helps.
Good Luck.
