Electric power steering
Power steering uses the 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 motor driven 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 wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for better control of the steer-
ing wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized KIA dealer.
✽ ✽
NOTICE
The following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illumi-
nate.
• The steering effort is high immediately 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 condi-
tion.
• 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 System does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized Kia dealer and have the
vehicle checked as soon as possible.
• 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 conditions. • When you operate the steering wheel
in low temperature, abnormal noise
could occur. If temperature rises, the
noise will disappear. This is a normal
condition.
