ful to the environment and
human health. Dispose the

Your vehicle may be equipped with
an electronic engine immobilizer sys-
tem to reduce the risk of unautho-

prised of a small transponder in the
ignition key and electronic devices
inside the vehicle.
With the immobilizer system, when-
ever you insert your ignition key into
the ignition switch and turn it to ON,
it checks and determines and verifies
that the ignition key is valid.

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.
