What to do in an emergency
1. Pull off the road and stop as soonas 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 hood, stop the vehicle.Do not open the hood 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 an
authorized HYUNDAI dealer 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 beenlost, 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 an
authorized HYUNDAI dealer 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
an authorized HYUNDAI dealer.
When overheating from low coolant, suddenly adding coolant
may cause damages in the motor
compartments. To prevent dam-
age, add coolant slowly in smallquantities.

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 thedrain plug while the
radiator is hot. Hotcoolant and steam
may blow out under pressure,
causing serious injury.
