Electric power steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the Engine
Start/Stop button is ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from the EPS relay after turning the
Engine Start/Stop button is ON or
OFF position.
• A 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 warning light will illuminate on
the instrument cluster. The steer-
ing 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. (Continued)
