Oil Pressure Warning Light This light shows low engine oil pressure. The light should turn on momentarily when the engine is started. If the light turns on while driving, stop the vehicle, and shut off the engine as soon as possible. A continuous chime will sound when this light turns on. Do not operate the vehicle until the cause is corrected. This light does not show how much oil is in the engine. The engine oil level must be checked under the hood. 11. Electronic Stability Program (ESP) Indicator Light/Traction Control System (TCS) Indicator Light - If Equipped If this indicator light flashes during acceleration, apply as little throttle as possible. While driving, ease up on the accelerator. Adapt your speed and driving to the prevailing road conditions, and do not switch off the ESP, or TCS - if equipped. The indicator light will flash when the ESP or TCS System is active and helping to improve vehicle stability. If the indicator light is on solid, ESP or TCS may not be able to function normally.
