The tires supplied on your new vehicle
are chosen to provide the best perform-
ance for normal driving.
The tire label located on the driver's side
center pillar gives the tire pressures rec-
ommended for your vehicle.The engine number is stamped on the
engine block as shown in the drawing.
The refrigerant label is located on the
engine hood.

Kia Hybrid-Electric Vehicle (HEV) uses
a gasoline engine and an electric
motor for power. The electric motor is
run from a 270V high voltage HEV bat-
tery.
The HEV computer decides when to
use the engine and when to use elec-
tric motor, according to driving condi-
tions. At times, both are used simulta-
neously.
By turning off the engine under cer-
tain conditions and using the electric
motor alone, the HEV system saves
fuel.
When the HEV battery reaches a low
state of charge, the engine will cycle
on and off to recharge the battery.
Charging also occurs when decelerat-
ing by using regenerative braking.Hybrid System Display
Many of the displays provide information
about the hybrid system, such as the
ECO Level and ECO Score.
The ECO Level displays inform the driver
of the vehicle's fuel efficiency. If the vehi-
cle is driven economically, the ECO Level
rises. When the vehicle is driven in EV
mode, there is a reduction in carbon diox-
ide (CO2) emissions.
The Total ECO Score display indicates
the number of times the ECO Level has
reached its maximum.ECO Level display
When the vehicle is started, the ECO
Level display will indicate level number 4.
If you drive economically, the ECO Level
will increase. However, if you do not drive
economically, the ECO Level will
decrease.

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.

Kia hybrid system notifies the drivers of
energy flow in various operating modes.
Twelve Modes show drivers the current
operating condition.
Vehicle Stop
The mode means the vehicle at stop.

H6Starting the Hybrid System
1. Carry the smart key into the vehicle.
2. Make sure the parking brake is firmly
applied.
3. Place the shift lever in the P(Park) position.
In N (neutral) position, you can not
start the vehicle.
4. Depress the brake pedal.
5. Press the engine start/stop button.
6. The engine should be started without pressing the accelerator. In extremely
cold weather or after the vehicle has
not been operated fro several days, let
the engine warm up without depress-
ing the accelerator.
• Even if the smart key is in the vehicle,if it is far away from you, the engine
may not start.
in the ACC or ON position, if any door
is open, the system checks for the
smart key. If the smart key is not in
the vehicle, the warning, "Key is not
in vehicle" will come on, and if all
doors are closed, the chime will also
sound for about 5 seconds. The indi-
cator will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC position
or if the vehicle engine is on.
If the starting procedure is followed,
the "READY" symbol on the instru-
ment cluster will turn on. For more
details, Please check chapter 5.
ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a mod- erate rate and maintain a steady cruis-
ing speed. Don't make "jack-rabbit"
starts. Don't race between stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
The regenerative brake generates energy when the vehicle decelerates.
When the hybrid battery power is low, the hybrid system automatically
recharges the hybrid battery.
When the engine runs in "N" position, the hybrid system cannot generate
electricity. The hybrid battery cannot
recharge in "N" position. Please refer
to chapter 5.
STARTING THE HYBRID VEHICLE (SMART KEY)

H7
✽
✽NOTICE
In the hybrid system, the engine auto-
matically runs and stops. If the hybrid
system operates, the "READY" symbol
is illuminated.
In the following situations, the engine
may turn on and off automatically:
- When the hybrid battery is dis-
charged
- When the hybrid battery reaches a certain temperature.
