Kia Rio: Features of your vehicle / Steering wheel

Electric power steering (EPS)

Power steering uses a 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 electric 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 wheel 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 power steering checked by an authorized Kia dealer.

✽ NOTICE

The following symptoms may occur during normal vehicle operation:

• The steering effort is increased immediately after turning the ignition switch on. This happens as the system performs the EPS system diagnostics. When the diagnostics are completed, the steering wheel will return to its normal condition
• A click noise may be heard from the EPS relay after the ignition switch is turned to the ON or LOCK position.
• Motor noise may be heard when the vehicle is at a stop or at a low driving speed.
• 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 condition.
• When you operate the steering wheel in low temperature, noise may occur. If the temperature rises, the noise will likely disappear. This is a normal condition.
• When the charging system warning light comes on or the battery voltage is low (when the alternator or battery does not operate normally), the steering wheel may get heavy and become difficult to control or operate abnormally.

If the Electric Power Steering System does not operate normally, the warning light will illuminate on the instrument cluster. The steering wheel may require increased steering effort. Take your vehicle to an authorized Kia dealer and have the vehicle checked as soon as possible.
