Electric power steering

Power steering uses the motor to assist you in steering the vehicle. If the engine is off or if the power steering system becomes inoperative, the vehicle may still be steered, but it will require increased steering effort.

The motor driven power steering is controlled by the power steering control unit which senses the steering wheel torque and vehicle speed to command the motor.

The steering effort becomes heavier as the vehicle’s speed increases and becomes lighter as the vehicle’s speed decreases for better control of the steering wheel

Should you notice any change in the effort required to steer during normal vehicle operation, have the system checked by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.

NOTICE

The following symptoms may occur during normal vehicle operation:

  • The EPS warning light does not illuminate.

  • The steering effort is high immediately after turning the ENGINE START/STOP button is ON. This happens as the EPS system performs the diagnostics. When the diagnostics is completed, the steering effort will return to its normal condition.

  • A click noise may be heard from the EPS relay after the ENGINE START/STOP button is turned to the ON or OFF position.

  • Motor noise may be heard when the vehicle is at a stop or at a low driving speed.

  • The steering effort can suddenly increase, if the operation of the EPS system is stopped to prevent serious accidents when EPS control unit detects malfunction of the EPS system by self-diagnosis.

  • The steering effort increases if the steering wheel is rotated continuously when the vehicle is not in motion. However, after a few minutes, it will return to its normal conditions.

  • If the Electric Power Steering System does not operate normally, the warning light will illuminate or blink on the instrument cluster. If the power assistance of steering fails, you will need to use more force to steer. In this case, have the system inspected by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.

  • When you operate the steering wheel in low temperature, abnormal noise could occur. If temperature rises, the noise will disappear. This is a normal condition.
