Steering wheel
Electronic power steering
The power steering uses the motor to assist steering effort. If the engine is off or the power steering fails, the vehicle can still be steered, but the steering effort required will increase.
The power steering is controlled by the power steering control unit, which detects steering wheel torque and vehicle speed to control the motor.
The steering wheel becomes firmer as vehicle speed increases and lighter as vehicle speed decreases, to provide better steering control.
If you notice a change in the steering effort during normal vehicle operation, have the power steering checked at an authorized Kia dealer.
NOTICE
The following symptoms may occur during normal vehicle operation:
- The EPS warning light does not come on.
- The steering wheel becomes harder to turn after starting the engine. This occurs while the EPS performs its diagnostic sequence.
Tilt steering wheel
The tilt steering column allows you to adjust the steering wheel height before driving. You can also raise the steering wheel to provide more legroom when getting in and out of the vehicle.
The steering wheel should be adjusted to a comfortable position while allowing a clear view of the gauges and warning lights on the instrument panel.
WARNING- Never adjust the steering wheel angle or height while driving. You could lose control of the vehicle, causing serious or fatal injury or an accident.
- After adjusting the steering wheel, try to push it down or pull it up to make sure it is locked in position.

To change the steering wheel angle, lower the lock lever (1), adjust the angle (2) and height (3, if equipped) of the steering wheel, then raise the lever to lock the steering wheel in position. Be sure to adjust the steering wheel before driving.

Horn
To sound the horn, press the horn symbol on the steering wheel. Check the horn regularly to make sure it works properly.
NOTICE
To sound the horn, press the area marked with the horn symbol on the steering wheel (see illustration). The horn will only sound if you press in this area.
CAUTIONDo not strike the horn hard to make it sound.
Do not strike it with your fist.
Do not press the horn with a sharp object.

Heated steering wheel (if equipped)
With the engine start/stop button in the ON position, press the steering wheel heater button to heat the steering wheel. The indicator built into the button will illuminate. To turn off the steering wheel heater, press the button again. The indicator built into the button will go off. The heater turns off automatically after approximately 30 minutes of operation. If you turn the ignition back on within half an hour after the engine is turned off, the heater will remain on.
CAUTION- Do not install any covers on the steering wheel. This could damage the steering wheel heating system.
- Do not use solvents such as paint thinner, benzene, alcohol or gasoline to clean the heated steering wheel. This will damage the surface of the steering wheel.
- If the steering wheel surface is damaged by a sharp object, the heating element components may also be damaged.
