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 engine start/stop but-
ton on. This happens as the system
performs the EPS system diagnostics.
When the diagnostics is completed, the
steering wheel will return to its normal
condition.
• A click noise may be heard from the
EPS relay after the engine start/stop
button 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, noise could occur.
If temperature rises, the noise will dis-
appear. 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.

What to do in an emergency
9. Loosen the wheel nuts and
remove them with your fingers.
Slide the wheel off the studs and
lay it flat so it cannot roll away. To
put the wheel on the hub, pick up
the spare tire, line up the holes
with the studs and slide the wheel
onto them. If this is difficult, tip the
wheel slightly and get the top hole
in the wheel lined up with the top
stud. Then jiggle the wheel back
and forth until the wheel can be
slid over the other studs.
10. To reinstall the wheel, hold it on
the studs, put the wheel nuts on
the studs and tighten them finger
tight. The nuts should be installed
with their tapered small diameter
ends directed inward. Jiggle the
tire to be sure it is completely
seated, then tighten the nuts as
much as possible with your fin-
gers again.
11. Lower the car to the ground by
turning the wheel nut wrench
counterclockwise.Then position the wrench as shown
in the drawing and tighten the wheel
nuts. Be sure the socket is seated
completely over the nut. Do not stand
on the wrench handle or use an
extension pipe over the wrench han-
dle. Go around the wheel tightening
every other nut until they are all tight.
Then double-check each nut for
tightness. After changing wheels,
have an authorized HYUNDAI dealer
tighten the wheel nuts to their proper
torque as soon as possible.
Wheel nut tightening torque:
Steel wheel & aluminum alloy wheel:
65~79 lb·ft (9~11 kg·m)
WARNING
Wheels may have sharp edges.
Handle them carefully to avoid
possible severe injury. Before
putting the wheel into place, be
sure that there is nothing on the
hub or wheel (such as mud, tar,
gravel, etc.) that prevents the
wheel from fitting solidly
against the hub.
(Continued)
(Continued)
If there is, remove it. If there is
not good contact on the mount-
ing surface between the wheel
and hub, the wheel nuts could
come loose and cause the loss
of a wheel. Loss of a wheel may
result in loss of control of the
vehicle. This may cause serious
injury or death.

Maintenance
Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes, muf-
fler and hangers for cracks, deterioration,
or damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts as
necessary.
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant
Check the air conditioning lines and con-
nections for leakage and damage.
