WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned.
Check the oil as soon as possible
and have the vehicle serviced.
Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally the indicator light then
goes off.
If the light comes on and stays on,
it means that oil is not flowing
through the engine properly.
The vehicle could be low on oil and
