STEERING WHEEL
Electronic power steering (EPS)
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 electronic power steering is con‐
trolled 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 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:
(Continued)
(Continued)
• 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
EPS system performs the diag‐
nostics. 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 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 can suddenly
increase, if the operation of the
EPS system is stopped to prevent
serious accidents when EPS con‐
trol unit detects malfunction of
the EPS system by self-diagnosis.
(Continued)
(Continued)
• 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.
• If the Electronic Power Steering
System does not operate normal‐
ly, the warning light will illuminate
on the instrument cluster. The
steering wheel may become diffi‐
cult to control or operate abnor‐
mally. Take your vehicle to a pro‐
fessional workshop and have the
system checked as soon as possi‐
ble. Kia recommends to visit an
authorized Kia dealer/service part‐
ner.
• 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.
