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 steering sys-
tem becomes inoperative, the vehicle
may still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by a power steering control 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 steering control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
✽ ✽
NOTICE
The following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illu-
minate.
• The steering gets heavy 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 (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 steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized HYUNDAI dealer and have
the vehicle checked as soon as possible.
(Continued)(Continued)
• When the vehicle is stationary, if you
turn the steering wheel all the way to
the left or right continuously, the
steering wheel becomes heavier from
the end. But this is for your safety, not
system malfunction. As time passes,
the steering wheel return to its normal
condition.
• 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.
• When the charging system warning
light comes on or the voltage is low
(When the alternator (or battery) does
not operate normally or it malfunc-
tions), the steering wheel may get
heavy and become difficult to control
operate abnormally.
