Features of your vehicle
Electric power steering
Power steering uses the 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 the power steering con-
trol 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 steering wheel.
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.
✽ ✽NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort is increased
immediately after turning the igni-
tion switch on. This happens as the
system performs the EPS system
diagnostics. When the diagnostics
are 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.
• The steering effort increases if the steering wheel is rotated continuous-
ly 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.
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.

CAUTION- Fuse Replacement
Do not input any other objectsexcept fuses or relays intofuse/relay terminals such as adriver or wiring. It may causecontact failure and system mal-function.
WARNING - Electrical Fire
Always ensure replacement
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
WARNING
When replacing a blown fuse or relay, make sure the new
fuse or relay fits tightly into
the clips. Failure to tightly
install the fuse or relay may
cause damage to the wiring
and electric systems.
Do not remove fuses, relays and terminals fastened with
bolts or nuts. The fuses,
relays and terminals may not
be fastened correctly which
may cause vehicle damage.

The high voltage Hybrid battery is
used to operate the electric motor
and other components. High voltage
is dangerous if touched.
Your vehicle is equipped with orange
colored insulation and covers over
the high voltage components to pro-
tect people from electric shock. High
voltage warning labels are attached
to some system components as
additional warnings. Your vehicle's
hybrid system should therefore only
be inspected or repaired by an
authorized Kia dealer.
WARNING- High voltagecomponents
Never touch orange or high
voltage labeled components
including wires, cables, and
connections. If the insulators or
covers are damaged or
removed, severe injury or death
from electrocution may occur.

WARNING- Touching HPCU
When replacing fuses or relays
under the hood, do not touch
the HPCU in the engine com-
partment. Touching the HPUC
cause death or severe injury
from electrocution.
