Starting the Engine

When first starting the vehicle, the engine idle speed will be elevated to allow the catalytic converter, an emissions control device, to quickly reach operating temperature.

After approximately 20 seconds, the engine will begin to transition to its normal, quieter idle speed, which can vary depending on the temperature. This is normal operation.
