What to do in an emergency
6
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 vehicle
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, stop the vehicle immediately and call the
nearest 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 been lost,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indicatesthere is a leak in the cooling sys-tem and we recommend that the
system be checked by an author-
ized HYUNDAI dealer.

Maintenance

Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction Gear Fluid
Inspect the reduction gear fluid according to the maintenance sched-
ule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 4 specification.
Brake Discs, Pads, Calipers
and Rotors
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 the
vehicle 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.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

MaintenanceC
C OO OO LLAA NN TT
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN
marks on the side of the coolant
reservoir when the parts in the motor
compartment is cool.
If the coolant level is low, have your
vehicle inspected by an authorized
HYUNDAI dealer. Use only designat-
ed coolant water for electric vehicles,
adding other types of water or
antifreeze can damage the vehicle. The 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.
OAEE076002L
Since a specific coolant water is
applied for electric vehicles,replenishment of other
antifreeze or water may cause
problems to the vehicle.
WARNING
The electric motor for the cool-
ing fan may continue to operate
or start up when the vehicle isnot running and can cause seri-
ous injury. Keep hands, clothing
and tools away from the rotat-
ing fan blades of the coolingfan.
