Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low) or 0” level, the vehi-
cle automatically operates the
engine to charge the battery. However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the “L (Low) or 0”
level, we recommend the vehicle be
checked by an authorized Kia dealer.
✽✽
NOTICE
Never try to start the vehicle if the
fuel tank is empty. In this condition,
the engine cannot charge the high
voltage battery of the hybrid system.
If you try to start the vehicle when
the fuel is empty, the high voltage
battery will become discharged and
be damaged.

5. HPCU (Hybrid Power Control Unit)
6. High-voltage battery system
7. Regenerative brake system

❈ The actual shape may differ from
the illustration.
The Hybrid battery uses high voltage to
operate the electric motor and other
components. High voltage is dangerous
if touched.
Your vehicle is equipped with orange
colored insulation and covers over the high voltage components to protect
people from electric shock. High voltage
warning labels are attached to some system components as additional

WARNING
nHot Components
When the hybrid battery system op‐erates, the HEV battery system canbe hot. Heat burns may result fromtouching even insulated componentsof the HEV system.
Safety plug
DANGER
Never touch the safety plug. Safetyplug is attached to high voltage hy‐brid battery system. Touching safe‐ty plug will result in death or seriousinjury. Service personnel should fol‐low procedure in service manual.
Some special features of the
hybrid vehicle
Hybrid vehicles sound different than
gasoline engine vehicles. When the hy‐ brid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the accelerator pedal rapidly, you may hear
a sound. When you apply the brake
pedal, you may hear a sound from the regenerative brake system. When the
hybrid system is turned off or on, you
may hear a sound in the engine com‐ partment. If you depress the brake
pedal repeatedly when the hybrid sys‐
tem is turned on, you may hear a sound in the engine compartment.
None of these sounds indicate a prob‐
lem.
They are characteristics of hybrid vehi‐ cles. When the hybrid system is turned on,
the engine may run. This does not indi‐
cate a malfunction. If the "READY" symbol is on, the hybrid system is op‐
erating. Even if the gasoline engine is
off, you can operate the vehicle.
The HEV system may emit electromag‐ netic waves which can affect the per‐
formance of electronic devices applian‐
ces, such as laptop computers, which are not part of the vehicle design.
If you park the vehicle for a long time,
the hybrid system will discharge. You
need to drive the vehicle several times per month to maintain a charge.
When you start the hybrid system in
the "P" transmission position, the
"READY" symbol is illuminated in the cluster. The driver can drive the vehicle
even if the engine is stopped.
WARNING
When you leave the vehicle, youshould turn off the hybrid system. Ifyou depress the accelerator pedal bymistake and the vehicle is not in the"P" position, the vehicle will acceler‐ate. This may result in serious injuryor death.

❈The actual air bags in the vehicle
may differ from the illustration. Curtain air bags are located along both
sides of the roof rails above the front and rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact colli‐
sions, depending on the crash severity, angle, speed and point of impact. How‐
ever, when the side deployment
threshold is satisfied at front impact, the side air bags may deploy.
The curtain air bags may deploy on the
side of the impact side.
The curtain air bags are not designed
to deploy in all side impacts or rollover situations.
