CHANGE OIL SOON INDICATOR
2003 H2
1. The Oil Life System will show when to change the engine oil and oil filter. This will usually occur
between 3000 and 7500 miles since the last oil change. Under severe conditions, the indicator may come
on before 3000 miles. The system will not detect dust in the oil. Reset the system when the oil has been
changed.
2. To reset oil life system, turn ignition ON, with engine OFF. Fully push and release the accelerator pedal
slowly 3 times within 5 seconds. If the CHANGE OIL SOON light flashes, the system is resetting. Turn
ignition OFF. Start engine and all to idle. The oil life will change to 100 percent. If the CHANGE OIL
SOON indicator comes back on, the system has not reset. Repeat the procedure.
2004 H2
The vehicle has a computer system that has a change engine oil light, indicating when to change the engine oil
and filter. See Fig. 1 . This is based on engine revolutions and engine temperature, and not on mileage. Based
on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil
life system to work properly, the system must be reset every time the oil is changed.
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary.
The change engine oil light will come on. The oil must be changed as soon as possible. It is possible that, if the
vehicle is driven under the best conditions, the oil life system may not indicate that an oil change is necessary
for over a year. However, the engine oil and filter must be changed at least once a year and at this time the
system must be reset. If the system is ever reset accidentally, the oil must be changed at 3000 miles since the
last oil change. Remember to reset the oil life system whenever the oil and filter is changed.
1. Press the fuel information button until Engine Oil Life appears on the screen.
NOTE:
Most vehicles are equipped with a Malfunction Indicator Light (MIL) or check
engine light. If light comes on and remains on while driving, the vehicle requires
some type of repair. See appropriate service and repair information. After
repairing fault(s) and clearing fault code(s), the MIL or check engine light
should go out. Some models may use a dual-function indicator light, which is
also used to indicate emission component service is due. After performing
required service, reset indicator light.
NOTE:
This article is only to be used for resetting maintenance reminder lights (when
applicable). Some models (not all) may be equipped with one or more resetable
maintenance reminder lights indicating maintenance is required. Once required
maintenance services are performed, resetting of lights may be required.
Information is provided to reset these lights where applicable.
