What to do in an emergency
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift to P (Park) and set the park- ing brake. If the air conditioning is
on, turn it off.
3. If coolant is running out under the vehicle or steam is coming out
from the bonnet, stop the vehicle.
Do not open the bonnet until the
coolant has stopped running or
the steaming has stopped. If there
is no visible loss of coolant and no
steam, leave the vehicle running
and check to be sure the cooling
fan is operating. If the fan is not
running, turn the vehicle off.
4. Check for coolant leaking from the radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop). 5. If coolant is leaking out, turn off
the vehicle immediately and we
recommend that you call a
HYUNDAI authorised repairer for
assistance.
6. If you cannot find the cause of the overheating, wait until the radiator
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark. 7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer for
assistance.
Serious loss of coolant indi- cates there is a leak in the cool-
ing system and we recommend
that the system be checked by a
HYUNDAI authorised repairer.
When overheating from low coolant, suddenly adding coolant
may cause damages in the motor
compartments. To prevent dam-
age, add coolant slowly in small
quantities.

Do not remove the coolant cap
when the radiator is hot. This
can allow coolant to blow out of
the opening and cause serious
burns.
WARNING

7-10
MaintenanceThe electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
Never remove the
coolant cap or the
drain plug whilst the
radiator is hot. Hot
coolant and steam
may blow out under pressure,
causing serious injury.

WARNING
OAEE076002
The electric motor for
the cooling fan may
continue to operate
or start up when the
vehicle is not operat-
ing and can cause serious
injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING (Continued)
Turn the vehicle off and wait
until the parts in the motor com-
partment cools down. Use
extreme care when removing
the coolant cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to the
first stop. Step back whilst 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 counterclock-
wise to remove it.
