2012 KIA Optima Hybrid tow

725
Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
distilled (deionized) water to provide pro-
tection against freezing and corrosion.
Bring the level to F, but do not overfill. If
frequent additions are required, see an
authorized Kia dealer for a cooling sys-
tem inspection.
(Continued)
The engine coolant level is influ-enced by hybrid system tempera-
ture. Before filling the engine
coolant and/or inverter coolant,
turn the hybrid vehicle off, fill the
engine coolant and/or inverter
coolant carefully.
Turn the engine off and wait until it 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.
Even if the engine is not operat- ing, do not remove the radiator
cap and/or inverter or the drain
plug while the engine and radia-
tor are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.

WARNING
The electronic motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure and
vehicle speed. It may sometimes
operate even when the engine is
not running. Use extreme caution
when working near the blades of
the cooling fan so that you are not
injured by the rotating fan blades.
As the engine coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.

H3
Total ECO Score display
If your ECO Level reaches its maximum,
your Total ECO Score automatically rises
by 1 point. Total ECO Score points are
saved and accumulate over time.
The image displayed on Total ECO Score
will change continuously, adding leaves
and flowers to a branch.
State of charge
The state of charge (SOC) gauge indi-
cates the hybrid battery's charge level. If
the SOC is near Low (L) level, the vehicle
automatically operates the engine to
charge the battery. However, if the serv-
ice indicator and MIL(Malfunction indica-
tor lamp) turn on when the State of
Charge(SOC) is near L, the vehicle
should be towed. Refer to the chapter 6.

WARNING
Never crank the engine for a pro-
longed time without the engine
starting. This could result in the
HEV battery becoming totally dis-
charged and is likely to be dam-
aged.

H14
If An Accident Occurs
Avoid the engine compartment.
Avoid any orange or high voltagewires, cables, or components.
Assume that a high voltage component is exposed and move away from the
vehicle as promptly as possible.
Refer to Chapter 6 for towing informa- tion or call Kia Roadside Assistance.
When the hybrid vehicle shuts off
When the high voltage battery or 12-volt
battery discharges, or fuel tank is empty,
the hybrid system may not operate.
If the Hybrid system stops operating
while the vehicle is moving, reduce the
vehicle speed gradually. Pull your vehi-
cle off the road in a safe area, and shift
the transmission in to Park (P) position
and;
1. Turn on the hazard warning flashers.
2. Set the start button at OFF, and try tostart the Hybrid system by applying the
brake pedal and pushing the start but-
ton.
3. If the Hybrid system will not operate, refer to "EMERGENCY STARTING" in
chapter 6. Before you try to jump start the vehicle,
confirm the fuel level. If the fuel level is
low add more fuel before attempting as
emergancy start.
