2.
Av

oid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
3.
Turn o

ff all electrical devices such as
radios, lights, air conditioning, etc.

OFF.
OCN7070002
4. Connect the jumper cables in
the ex act sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
5.
Connect the other end o

f the jumper
cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
6.
Connect the second jumper cable to
the black, nega

tive (-) battery/ chassis
ground of the assisting vehicle (3). 7.
Connect the other end o

f the second
jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
8.
Do not allo
w the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.
9.
Opera
te your vehicle for at least
30 minutes of driving or at least
60 minutes of engine running at
idle before shutting off the engine.
Without sufficient time to charge
the battery the vehicle will reoccur
another no start. You can also visit
your nearest dealer to request the
battery be charged and tested.
If your vehicle will not start after a few
attempts, it probably requires servicing.
In this event please seek qualified
assistance. If the cause of your battery
discharging is not apparent, have your
vehicle checked by an authorized
HYUNDAI dealer.

exact reverse order you connected them:
1.
Disconnect the jumper cable from the
black, nega

tive (-) chassis ground of
your vehicle (4).
2.
Disconnect the other end o

f the
jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle (3).
3.
Disconnect the second jumper cable
from the r

ed, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
4.
Disconnect the other end o

f the
jumper cable from the red, positive (+)
jumper terminal of your vehicle (1).

Emergency Situations
8-6
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 r
oad and stop as soon as it
is safe to do so.
2.
Put the vehicle in P (P

ark), and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3.
If engine coolant is running out under
the v

ehicle 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 to see if the w

ater pump drive
belt is missing.
(1)
If it is not missing, check t
o see that
it is tight.
(2)
If the drive belt seems t
o be
satisfactory, 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 the wa
ter pump drive belt is
broken or 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.
