Acura TSX maintenance Schedule

Performing regular maintenance according to the factory-recommended Maintenance Schedule is the best way to keep your Acura running in optimal condition.

Each vehicle has its own maintenance needs, so Acura develops specific maintenance schedules based on model equipment, such as transmission choice or the addition of a towing package.

The Maintenance Schedule calculates service needs based on your car's mileage. It checks engine-operating conditions and helps coordinate oil service dates and other maintenance check-ups. Prevent problems before they occur

Q: How does the Acura Maintenance Minder work?

A: The maintenance minder system shows engine oil life in the information display to let the owner know when it is time to have the engine oil replaced and regular engine maintenance done. There is no longer a maintenance schedule in the owner's manual. The system shows engine oil life as a percentage, which drops over time as the vehicle racks up miles. It starts out at 100% with fresh engine oil, and winds down to 0%, signaling the oil life is over.

Q: How does the Acura Maintenance Minder know when the 0% trigger occurs?

A: The system counts down oil life based on engine operating conditions (both normal and severe). The on-board computer continuously monitors engine operating conditions such as speed, engine temperature, ambient temperature, time, and vehicle use to determine when an oil change and regular maintenance is necessary.

Q: How do I operate the system?

A: The Acura Maintenance Minder is very easy to use. As the on-board computer continuously monitors your vehicle, it provides continuous information on the remaining engine oil life left - simply depress the Select/Reset knob on the information display and you will see use progression.

When the on-board computer determines that your vehicle has reached 15% of remaining life, it will turn on the Maintenance Minder light for you. In addition, each time the vehicle is started; the information center will default and automatically display the percentage of remaining life. To return to the odometer/tripometer, simply depress the Select/Reset knob.

The following chart will explain exactly when service is due:

Oil Life %	Message	What to do
15%	Service Due Soon	Plan to take your vehicle in for service.
5%	Service Due Now	Take your vehicle in now for maintenance.
0%	Service Past Due	Service is overdue. Take your vehicle in now.

Q: What happens to the Maintenance Minder if I do not perform maintenance when the remaining life gets to 0%?

A: If you do not perform the recommended maintenance the display will start to show negative mileage. This indicates how many miles that the vehicle is past due for service.

Q: Along with the and the percentage of remaining life, there is a letter and sometimes, a number displayed - what do they mean?

A: All maintenance items in the display are in code. There are two codes: Main-codes and Sub-codes. Your vehicle will always be due for a main code, and at times for a sub-code. Please refer to your owner's manual, Acura Service History booklet, and the following chart to interpret the code:

Main Code	What it means:
	Replace just the engine oil
	Replace the engine oil, oil filter, rotate the tires, inspect the front and rear brakes, check the parking brake adjustment, and inspect other items specific to your vehicle

Sub Code
	Rotate the Tires
	Replace the air cleaner element, check the drive belt, and replace the dust and pollen filter
	Replace the transmission fluid and transfer fluid (if equipped)
	Replace the spark plugs, replace the timing belt (if equipped), inspect the water pump, and inspect valve clearance
	Replace the engine coolant
	Replace the rear differential fluid (if equipped)

Q: Why will there always be a Main-code?

A: The sub-codes are turned on when the main-codes are triggered. Main-codes are USER SPECIFIC and are triggered based on the vehicle's operating conditions. The system is designed to maximize customer convenience.

Q: Why is there only sometimes a Sub-code?

A: These items require maintenance on a time/mileage based schedule, similar to the maintenance schedules of the past. The Maintenance Minder also calculates time as it factors vehicle use and automatically moves up or delays the sub-codes so they get done with the main-codes.

For example, if tire rotation is normally done at 7, 500 miles, but the oil life ends around 6, 000 miles, the system will move up the tire rotation. Or, if the life appears to be ending around 9, 000 miles, the system will delay the rotation. In either case, you would see the maintenance item code A1 in the information display.

Q: How many miles can I expect to go between oil changes when using the system?

A: It will vary. The beauty of the Acura Maintenance Minder system is that it automatically adjusts the maintenance intervals based on engine operating characteristics, your driving habits, and the climate that you have operated your vehicle in. For instance, mild highway driving in a warm climate will maximize the interval between required maintenance. Depending on the vehicle, this could be as high as 12, 000 miles. On the other hand, short-trip driving in a cold climate may limit the maintenance interval to 3, 000 miles or less. In general, most people who combine city and highway driving find that the Acura Maintenance Minder will indicate maintenance needs about every 6, 000 miles. Most people maintain constant driving habits; this means that mileage between maintenance will be consistent.
