A locking differential, if equipped, is for
the rear wheel differential only. The fea-
tures of this locking differential are
described below:
Just as with a conventional differential,
the wheel on one side is allowed to turn
at a different speed from the wheel on
the other side when the vehicle is cor-
nering. The difference between the lock-
ing differential and a conventional differ-ential is that if the wheel on one side of
the vehicle loses traction, a greateramount of torque is applied to the rear
wheel on the other side to improve trac-tion.
✽✽
NOTICE
In a stationary position, the LD
(Locking Differential) will operate when
the difference of the revolution speed
between the rear right wheel and the
rear left wheel occurs.
The following procedures can be used to
confirm that the locking differential is
functioning properly:
(1) Position the vehicle so that one wheel is on a dry paved surface and the
other on ice, snow, mud, etc. Drive
the vehicle, and observe the opera-
tion of the locking differential. The
vehicle should not become stuck if
the differential is functioning properly.
(2) Depress the accelerator pedal gradu- ally, and then when traction is good,
depress it forcefully. If the vehicle
accelerates well, the differential is
functioning properly.
✽✽NOTICE
Usually a locking differential will oper-
ate and release automatically but occa-
sionally it may not release automatically.
At this time you will feel the tire is
dragged when you are driving or corner-
ing. You can release it manually by slight-ly turning the steering wheel right and
left while the vehicle is moving slowly.
LOCKING DIFFERENTIAL (IF EQUIPPED)
CAUTION
Never start the engine with the gearshift lever placed in the for-ward or reverse while one of the rear wheels is jacked up and the
other in contact with the ground; doing so may cause the vehicle tojump forward.
If one of the rear wheels begins to spin in mud, snow, etc., the vehi-
cle can sometimes be driven out by depressing the acceleratorpedal further; however, avoid run-
ning the engine continuously athigh rpm because doing so coulddamage the locking differential.

What to do in an emergency

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 installedwith their tapered small diameter
ends directed inward. Jiggle thetire 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 standon 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: 9~11 kg·m (65~79 lb·ft)
WARNING
Wheels may have sharp edges.
Handle them carefully to avoid
possible severe injury. Before
putting the wheel into place, besure that there is nothing on the
hub or wheel (such as mud, tar,
gravel, etc.) that interferes with
the wheel from fitting solidly
against the hub.
If there is, remove it. If there is not good contact on the mount-ing surface between the wheel
and hub, the wheel nuts couldcome 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
G051500AUN Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
G051600AUN Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.
G051700AUN
Parking brake
Inspect the parking brake system includ-
ing the parking brake lever and cables.
G051900AUN
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.G052100AUN Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
G052200AUN
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. G052300AEN
Power steering pump, belt and hoses
Check the power steering pump and
hoses for leakage and damage. Replace
any damaged or leaking parts immedi-
ately. Inspect the power steering belt (or
drive belt) for evidence of cuts, cracks,
excessive wear, oiliness and proper ten-
sion. Replace or adjust it if necessary.
G052500AUN
Air conditioning refrigerant (if equipped)
Check the air conditioning lines and con-
nections for leakage and damage.
