Most Hyundai vehicles are equipped with an electronic computer system, linked to the dashboard, that tells drivers when maintenance is required. If the driver neglects a service light, such as the “SERVICE REQUIRED” light, he or she runs the risk of damaging the engine - or worse, ending up stranded on the side of the road or causing an accident.
For these reasons, performing all scheduled and recommended maintenance on your vehicle is imperative to keep it running well, so you can avoid the many untimely, inconvenient, and possibly expensive repairs that come from neglect. Luckily, the days of scratching your head and performing diagnostics to find the service light’s trigger are gone. Hyundai’s mileage-based minder system is a simplistic on-board computer system that alerts owners about necessary maintenance schedules so they can address the issue promptly and without hassle. Once the mileage-based minder system is triggered, the driver knows to schedule an appointment to take the vehicle in for servicing.
How Hyundai’s mileage-based minder system works and what to expect
The sole function of Hyundai’s mileage-based minder system is to remind owners when to take their car in for a scheduled service. A message, “SERVICE IN”, will appear each time the ignition is switch turned to the “ON” position. The computer system tracks the engine miles from the time it was reset, and the light will trigger after a certain amount of miles driven (i.e. 5,000 miles, or 7,500 miles). When the system counts down to zero, it begins to track negative miles, or miles driven since the “SERVICE IN” light was triggered; the new service message will read “SERVICE REQUIRED.” At this point, your vehicle should have already been serviced, or it should be serviced as soon as possible.
Since the system is not algorithm-driven, like other more advanced maintenance reminder systems, it does not take into account the differences between light and extreme driving conditions, load weight, towing, or weather conditions, which are important variables that affect engine oil life and other engine components. Because of this, the maintenance light might not be effective for those who tow often, or often drive in extreme weather conditions and need the oil changed more frequently. That said, it also might not be effective for those who constantly drive on the freeway in fair weather conditions.
The Hyundai mileage-based minder system can be manually disabled, set, and/or reset, depending on factors such as what oil you use (synthetic/conventional), your driving habits, and the conditions under which you drive (is it snowy and hilly throughout the year, or maybe flat and sunny?). If the system has been turned off, the service message will read “SERVICE IN: OFF.” Consult the owner’s manual for information about how to operate the system.
This is not to say that a driver should neglect the maintenance light altogether. Be aware of your driving habits and conditions throughout the year and, as necessary, have a professional determine whether or not your vehicle needs servicing depending on your specific, most frequent driving habits and conditions.
Below is a helpful table that can give you an idea of how often you might need to change the oil in a modern vehicle (older vehicles often need more frequent oil changes):
- Note: Engine oil life is dependent not only on the factors listed above, but also on your specific vehicle model, year, and what type of oil is recommended. Check the owner’s manual for more information about what oil is recommended for your vehicle, and don’t hesitate to get in touch with one of our experienced professionals for advice.
When the “SERVICE REQUIRED” light is triggered and you schedule an appointment to have your vehicle serviced, Hyundai recommends a series of inspections that will help keep your car in good running order and can help prevent untimely and costly damages to the engine, depending on your driving habits and conditions.
Below is a graph of Hyundai’s recommended inspections for different mile intervals you might encounter during ownership. This graph is a general depiction of what a Hyundai maintenance schedule can look like. Depending on variables, like the vehicle year and model and your specific driving habits and conditions, this information is subject to change for maintenance frequency as well as the maintenance performed:
Once your Hyundai has been serviced, the “SERVICE REQUIRED” light will need to be reset. Some servicers will neglect to do this, which can lead to premature and unnecessary service light triggers. With only a few simple steps, you can learn how to do it yourself on newer third generation (2013-2015) models:
Step 1: Insert key into the ignition and turn the key to the “ON” position. Don’t start the vehicle. If you have a Hyundai with a smart key, press the “START” button twice without touching the brake pedal.
Step 2: Press “OK” if applicable. If the “SERVICE REQUIRED” information pops up on the screen, press the “OK” button and the system should be reset. If you have a car model without an “OK” button, proceed to the next step.
Step 3: Open the “INFORMATION” menu. Press the “MODE” button on the steering wheel and access the “INFORMATION” menu. Press “OK.”
Step 4: Set the mileage interval. Use the directional keypad to turn the “SERVICE INTERVAL” mode on and set the mileage interval recommended by a professional mechanic. Press “OK.”
Step 5: Turn the ignition to the “OFF” position. Start the engine to verify the system has been reset.
While the Hyundai mileage-based minder system can be used as a reminder to the driver to have the vehicle serviced, it should be used as a guideline that depends on how the vehicle is driven and under what driving conditions. Other recommended maintenance information is based on standard time tables located in the owner’s manual. This does not mean Hyundai drivers should ignore such alerts. Proper maintenance service will greatly extend the life of a vehicle, ensuring it is reliable, safe to drive, covered by the manufacturer’s warranty, and it can also provide a greater resale value.
Such maintenance tasks should always be performed by a qualified technician. If you have any doubts as to what the Hyundai maintenance system means or what services your vehicle may need, do not hesitate to contact our experienced professionals for advice.
