Features of your vehicle
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 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.
• 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 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 HYUNDAI dealer and
have the vehicle checked as soon as
possible.
• 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.
STEERING WHEEL
CAUTION
• If the Electric Power Steering
System does not operate normal-
ly, the warning light will illuminate
on the instrument cluster. The
steering wheel may become diffi-
cult to control or operate abnor-
mally. Take your vehicle to an
authorized HYUNDAI dealer and
have the vehicle checked as soon
as possible.
• When you operate the steering
wheel in low temperature, abnor-
mal noise could occur. If tempera-
ture rises, the noise will disap-
pear. This is a normal condition.
