Honda Maintenance Minder

To help vehicle owners know when scheduled maintenance is due,
Honda has introduced the maintenance minder system select models:

Q: How does the Honda 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 Honda 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

Q: How do I operate the system?

A: The Honda 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:

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

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, Honda Service History booklet, and the following chart to interpret the code:

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

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

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

A: It will vary. The beauty of the Honda 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 Honda 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.

Q: With my Honda truck, the first time the Honda Maintenance Minder turned on was 7,700 miles with an A1.
The second time, it turned on at 12,000 miles. Why did I only get 4,300 miles?

A: Driving habits. The first 7,700 were racked up with mostly highway driving in warm weather –
conditions that are favorable to oil life. The next 4,300 miles were racked up in warm weather, mostly
highway, AND mostly pulling a boat trailer. The Honda Maintenance Minder system is very intelligent and
monitors engine load to determine oil usage. With this situation, there were inconsistent driving
conditions and the Honda Maintenance Minder responded as such.

Q: I change my oil every 3,000 miles. How does this system help me?

A: It is recommended that you follow the Honda Maintenance Minder. While your driving habit may be such that
it is recommended every 3,000 miles, it may be that your driving characteristics indicate maintenance due at
2,500 miles, or, most people will see about a 6,000 mile recommendation. The system will help you and the
environment with the following benefits:

  • There will not be unnecessarily wasted natural resources (oil).
  • There will not be unnecessary hazardous materials that will require proper disposal (oil and filters).
  • As a consumer, you will only pay when it is necessary, saving you time and money.

Q: The oil change station recommends that I change my oil every 3,000 miles. Why should I not believe them?

A: The 3,000 mile oil change is a very conservative approach to maintaining your vehicle that dates back to
1968. Since then, there has been much advancement in both oil technology and engine design. These
advancements, along with the Honda Maintenance Minder, allow you to increase maintenance intervals without
risking harm to your engine. In addition, as your Honda dealer, we are trained by Honda and specialize in
Honda, this allows your dealer to know your car better than non-Honda service facilities.

Q: Typically my Honda Maintenance Minder light comes on at 6,500 miles, but I am only at 4,500 miles and am
going on vacation. I want to get my service done before I go. What should I d

A: It is recommended that you follow the Honda Maintenance Minder. However, should you choose to have
maintenance performed early, be sure to reset the Maintenance Minder light – this will keep the main-codes
and sub-codes synchronized.

Q: The Honda Maintenance Minder is telling me I need a “B” service. I choose to have only an “A” service
complete. Is there a problem?

A: Yes. The Honda Maintenance Minder is not just an “oil change” indicator, it makes recommendations for the
entire vehicle’s maintenance. Main and sub codes will get out of harmony and the Maintenance Minder cannot
properly predict required maintenances. When proper maintenance is followed, you will realize the following

  • Better resale value
  • Continued reliability
  • Longer vehicle life
  • Continued warranty coverage

Q: What do I do if I had the improper/not recommended service completed?

A: If you reset the Honda Maintenance Minder light, you reset the maintenance schedule of your vehicle. By
doing this, the Honda Maintenance Minder will not be able to properly predict required maintenance. Your
Honda dealer can reset the Honda Maintenance Minder system. Resetting the system is not as simple as
resetting the dash light, and you may be charged. Your Honda dealer will have to use a computer called the
Honda Diagnostic System (HDS) to complete what is called a forced activation – this will allow your vehicle
to have proper time and mileage set with the current maintenance completion.

When the dash light is reset, the input tells the on-board computer that ALL required maintenance was
performed. The Maintenance Minder system will not allow for line-item maintenance, the system requires
maintenance completion as indicated.

Q: I change my own oil. Should I reset the light?

A: The Honda Maintenance Minder is not just an oil change indicator, it reminds us of all maintenance
requirements. If you change your oil, it is important that you complete all Honda Maintenance Minder
recommendations and reset the light.

Q: I use synthetic oil. Should I expect to get more miles before the Honda Maintenance Minder indicates that
I need an oil change?

A: Honda does not recommend the use of synthetic oils as your Honda was designed and engineered based on the
oil recommended in your owner’s manual. The Honda Maintenance Minder calculates your vehicle’s needs based
on the oil recommended by the Honda engineers that designed your engine. The use of synthetic oil will not
extend the oil change interval.

Q: My husband and I equally share our Maintenance Minder Honda, does the system average our driving styles
to determine when maintenance is due?

A: No. The Honda Maintenance Minder is an intelligent system and monitors every drive cycle. A drive cycle is
defined as each time the car is turned on and off.

Q: I have taken my vehicle to a non-Honda facility and had the oil changed, the facility did not know how to
reset the Honda Maintenance Minder light. Will my Honda dealer reset it for me?

A: That depends. It is very important that all recommended maintenance be completed, if more than just an oil
change was necessary, your Honda dealer would be doing you a disservice by resetting the light as the light
is not just an oil change indicator – it monitors the complete maintenance requirements of your vehicle.

In addition, if you racked up miles before you came to the dealer, there has been wear and degradation of
the oil in your vehicle – your Honda dealer may have to change the oil again to properly set your Honda
Maintenance Minder.

QQ: Do I have to check my oil level with the Honda Maintenance Minder System?

A: Yes. The system does not sense oil level. Please follow the owner’s manual recommendations for Service
Station Procedures.

Q: I have driven 6,000 miles since my last maintenance, and the light has not come on.When checking the oil,
it looked dirty.What do I do?

A: The oil may discolor under normal conditions, depending on driving conditions. This is a normal condition.

Q: I have a need to know what the next recommended service will be. Can the Honda technician tell me?

A: Yes.Your Honda technician has been trained on the Honda Maintenance Minder and will use the Forced
Activation mode to determine what the next recommended services are. The option to check this will only work
between 100% oil life and 16% oil life, as when the system gets to 15%, it automatically turns on.

Q: My Honda is equipped with break-in oil, should I change it early?

A: No. To ensure proper engine break-in, the factory-fill engine oil needs to remain in the engine until the
first scheduled maintenance interval.

The factory fill oil is the same as Honda Service Replacement Oil. The difference is the Molybdenum
lubricant that is applied to specific internal engine components.
