CAUTION
• Improper jump starting procedure
can result in battery explosion and
acid burn hazard.
• Loosely connected battery cables
could damage the electronic control

An inappropriately disposed
battery can be harmful to the
environment and human health.
Dispose the battery according to
your local law(s) or regulation.
Jump starting procedure

that the jumper cables will reach, but
do not allow the vehicles to touch.
2. Avoid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in N (Neutral,

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and
tools away from the moving
parts such as the cooling
fan and drive belt to
prevent serious injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
WARNING
NEVER remove the radiator
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.

wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.

slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.

clutch fluid conforming to DOT 3 or 4
specification.
Parking brake

Check the rear brake drums and linings
for scoring, burning, leaking fluid,
broken parts, and excessive wear.
Brake pads, calipers and discs
Check the pads for excessive wear, discs
for run out and wear, and calipers for
fluid leakage.
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 necessary, repack the grease.
