Kia Optima: Warning Lights/Audible Indicators Checking OperationAll the warning lights, except the brake warning light, are checked by turning the ignition switch ON (you do not need to start the engine). Any light that does not come on should be checked by an Authorized Kia Dealer.
If the brake system warning light does not come on when the ignition switch is in the START position, have the system checked by an Authorized Kia Dealer.
After starting the engine, check to make sure that all warning lights are off. If any are still on, this indicates a situation that needs attention. When releasing the parking brake, the brake system warning light should go off.
