Oil pressure light
The light should turn off after a few seconds. If the light stays on or
illuminates when the engine is running, your vehicle has lost oil
pressure and continued operation will cause severe engine damage.
If your vehicle loses engine oil pressure:
1. Pull off the road as soon as safely possible.
2. Turn off the engine. If you do not stop the engine as soon as
safely possible, severe engine damage could result.
3. Check the oil level following the instructions on checking and
adding engine oil in this owner guide. (See Engine oil in the
index.) Make sure your vehicle is on level ground.
4. If the level is low, add as much oil as necessary before you drive
your vehicle again. Do not drive your vehicle if the oil pressure
light is on, even if the oil level is correct. For more information about
adding oil, see Engine oil, checking in the Index.
