STEERING WHEEL
Electric power steering
Power  steering  uses  the  motor  to  as‐sist  you  in  steering  the  vehicle.  If  the
engine  is  off  or  if  the  power  steering
system  becomes  inoperative,  the  vehi‐ cle  may  still  be  steered,  but  it  will  re‐
quire increased steering effort. 
The  motor  driven  power  steering  is
controlled  by  the  power  steering  con‐ trol  unit  which  senses  the  steering
wheel  torque,  steering  wheel  position
and vehicle speed to command the mo‐ tor.
The steering wheel becomes heavier as
the  vehicle’s  speed  increases  and  be‐
comes lighter as the vehicle’s speed de‐ creases  for  better  control  of  the  steer‐
ing wheel.
Should you notice any change in the ef‐
fort required to steer during normal ve‐ hicle  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 il‐
luminate.
•The steering effort is high imme‐
diately after turning the ignition
switch on. This happens as the
system performs the EPS system
diagnostics. When the diagnostics
is 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.

•If the Electric Power Steering Sys‐
tem does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer‐
ing wheel may become difficult to
control or operate abnormally. In
this case, have the system inspec‐
ted by a professional workshop.
Kia recommends to visit an au‐
thorized Kia dealer/service part‐
ner.
•The steering effort increases if
the steering wheel is rotated con‐
tinuously when the vehicle is not
in motion. However, after a few
minutes, it will return to its normal
conditions.
•When you operate the steering
wheel in low temperature, abnor‐
mal noise could occur. If tempera‐
ture rises, the noise will disappear.
This is a normal condition.
