All warning lights are checked by turning the ignition switch ON (do not start the engine). If any light that does not illuminate, we recommend that the system be 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.
The following warning and indicators are introduced in the previous pages.
