The Electronic Control Suspension (ECS) controls the vehicle suspension automatically to maximize driving comfort by taking into account the driving conditions such as speed, surface of the road, cornering, stopping requirements and acceleration. If the ECS warning message “Check Electronic Suspension” comes on, you may have a problem with the ECS system. If this occurs, have the vehicle inspected by a professional workshop. Kia recommended to visit an authorised Kia dealer/service partner.
