What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Turn on the emergency warning
flasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out
from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner.4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine.5. Check whether the engine coolant
temperature is low enough by
checking its temperature. If the
engine coolant level is low, please
check the connecting parts
between the radiator hose, heater
hose, and water pump for any signs
of leakage. When there is no sign of
leakage, please refill the engine
coolant. If causes and signs of
engine overheating such as warn-
ing light illumination, engine coolant
leakage, or cooling fan malfunction
are found, stop the vehicle the ear-
liest. Then, call the nearest author-
ized Kia dealer for assistance.
WARNING- Under the
Hood
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING- Radiator Cap
Do not remove the
radiator cap when the
engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.

Maintenance
8 7
At least monthly:
Check the coolant level in the
engine coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year
(i.e., every Spring and Fall) :
Check the radiator, heater and air
conditioning hoses for leaks or
damage.
Check the windshield washer
spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes,
shields and clamps.
Check the lap/shoulder belts for
wear and function.
At least once a year :
Clean the body and door drain
holes.
Lubricate the door hinges and
check the hood hinges.
Lubricate the door and hood locks
and latches.
Lubricate the door rubber weather-
strips.
Check the air conditioning system.
Inspect and lubricate dual clutch
transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

Engine coolant
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 MAX and MIN marks on the
side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to MAX, but do not
overfill. If frequent additions are
required, see an authorized Kia deal-
er for a cooling system inspection.
Inverter coolant
The coolant level should be filled
between MAX and MIN marks on the
side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to MAX, but do not
overfill. If frequent additions are
required, see an authorized Kia deal-
er for a cooling system inspection.
WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. It may
sometimes operate even when
the engine is not running.
