(g) Engine Oil Replacement Reminder Light (for
vehicles sold in U.S.A.)
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to the
"ON" position and will go off after about a few seconds.
When you drive for about 8000 km (5000 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to the "ON" position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 12000 km (7500 miles), the light will come on after the
ignition key is turned to the "ON" position. The light will remain
on thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road conditions. If the light comes on, replace it as soon as
possible.
GAUGES, METERS AND SERVICE REMINDER INDICATORS
The system must be reset after the engine oil replacement.
Reset the system by the following procedure:
1. Turn the ignition key to the "OFF" position with the odometer
reading shown. (For details, see "Odometer and trip meter" on
page 73.)
2. Turn the ignition key to the "ON" position while holding down
the "ODO/TRIP" button.
Hold down the button for at least 5 seconds. The odometer
indicates "000000" and the light goes off.
If the system fails to reset, the light will continue flashing.
