STEERING WHEEL
Electronic power steering
Power steerinþ uses the motor to as‐
sist you in steerinþ the vehicle. Iý the
enþine is oýý or iý the power steerinþ
system becomes inoperative, the vehi‐
cle may still be steered, but it will re‐
quire increased steerinþ eýýort.
Electronic power steerinþ is controlled
by the power steerinþ control unit
which senses the steerinþ wheel torque
and vehicle speed to command the mo‐
tor.
The steerinþ eýýort becomes heavier as
the vehicle s speed increases and be‐
comes liþhter as the vehicle s speed de‐
creases ýor better control oý the steer‐
inþ wheel.
Should you notice any chanþe in the eý‐
ýort required to steer durinþ normal ve‐
hicle operation, have the
checked by a proýessional workshop.
Kia recommends to visit an authorized
Kia dealer/service partner.

durinþ normal vehicle operation:
(Continued)
(Continued)
• The EPS warninþ liþht does not il‐
luminate.
• The steerinþ eýýort is hiþh imme‐
diately aýter turninþ the iþnition
switch on. This happens as the
EPS system perýorms the diaþ‐
nostics. When the diaþnostics is
completed, the steerinþ eýýort will
return to its normal condition.
• A click noise may be heard ýrom
the EPS relay aýter the iþnition
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
system
drivinþ speed.
• The steerinþ eýýort can suddenly
increase, iý the operation oý the
EPS system is stopped to prevent
serious accidents when EPS con‐
trol unit detects malýunction oý
the EPS system by selý-diaþnosis.

• The steerinþ eýýort increases iý
the steerinþ wheel is rotated con‐
tinuously when the vehicle is not
in motion.
However, aýter a ýew minutes, it
will return to its normal conditions.
• Iý the Electronic Power Steerinþ
System does not operate normal‐
ly, the warninþ liþht will illuminate
on the instrument cluster. The
steerinþ wheel may become diýýi‐
cult to control or operate abnor‐
mally. In this case, have the sys‐
tem inspected by a proýessional
workshop. Kia recommends to visit
an authorized Kia dealer/service
partner.
• When you operate the steerinþ
wheel in low temperature, the
steerinþ eýýort may be hiþh and
abnormal noise could occur. Iý
temperature rises, the noise will
disappear. This is a normal condi‐
tion.
