5-24 Instruments and Controls When the Light Is On Steady This indicates that one or more of the tires are significantly underinflated. A Driver Information Center (DIC) tire pressure message may also display. See Tire Messages on page 5‑42. Stop as soon as possible, and inflate the tires to the pressure value shown on the Tire and Loading Information label. See Tire Pressure on page 10‑51. When the Light Flashes First and Then Is On Steady If the light flashes for about a minute and then stays on, there may be a problem with the TPMS. If the problem is not corrected, the light will come on at every ignition cycle. See Tire Pressure Monitor Operation on page 10‑54. Engine Oil Pressure Light 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 it might have some other system problem. If the vehicle is a hybrid, see the hybrid supplement for more information. Notice: Lack of proper engine oil maintenance can damage the engine. Driving with the engine oil low can also damage the engine. The repairs would not be covered by the vehicle warranty. Check the oil level as soon as possible. Add oil if required, but if the oil level is within the operating range and the oil pressure is still low, have the vehicle serviced. 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.

This light and a chime come on when the fuel tank is low on fuel. The Driver Information Center also displays a FUEL LEVEL LOW message. See Fuel System Messages on page 5‑39 for more information.
