The maintenance minder system shows engine oil life in the information display to let you know when it's time to have the engine oil replaced and
regular maintenance done. There is no longer a maintenance schedule in the O/M.

winds down to 0%, signaling the oil life is over. The system counts down oil life based on engine operating conditions (both normal and severe). If the
engine runs at higher temperatures and rpm, or at low temperatures during short trips, the oil life will deplete faster than an engine running under more
normal conditions.
Depending on the oil life percentage, the system shows three different messages when you turn the the ignition switch to ON (II). Here's what you
could see:
When the oil life reaches 15%, you’ll also see a two-part maintenance item code.
This code tells you what items need servicing when you have the engine oil replaced. The first part of the code is the main code. It's either A or B,
never both. Here's what they mean:
The second part of the code is the subcode. It's numbered 1 thru 5 in vehicles without 4WD, and 1 thru 6 in vehicles with 4WD. These subcodes can
