AUX. BATTERY SAVER+ (For
Plug-in Hybrid, if equipped)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.
✽ ✽NOTICE
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the LCD display. For more infor-
mation, refer to the "System setting"
on the following page.
Mode

When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ periodically acti-
vates according to the auxiliary bat-
tery status.

When the engine start/stop button is
in the ON position with the charging
connector plugged in, the function
activates according to the auxiliary
battery status to prevent over-dis-
charge of the auxiliary battery.
✽ ✽NOTICE
The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function
will stop activating, judging that
there is a problem with the auxiliary
battery. In this case, drive the vehi-
cle for some period of time. The
function will start activating if the
auxiliary battery returns to normal.
CAUTION
The Aux. Battery Saver+ func-
tion cannot prevent batterydischarge if the auxiliary bat-tery is damaged, worn out,used as a power supply orunauthorized electronicdevices are used.
If the Aux. Battery Saver+ function was activated, a mes-sage will be displayed on theinstrument cluster and thehigh voltage battery level mayhave decreased.

H36
System setting
The driver can activate the Aux.
Battery Saver+ function by placing
the engine start/stop button to the
ON position and by selecting:
"User Settings \bOther Features \b
Aux. Battery Saver+"
LCD message
This message is displayed when the
Aux. Battery Saver+ function has
been completed when the vehicle is
turned ON.
However, if the LCD message pops
up frequently, have your vehicle`s
auxiliary battery or electric/electronic
components serviced by an author-
ized Kia dealer.
ODEP047473N
WARNING
The Aux. Battery Saver+ relies
on the high voltage battery to
charge the 12V battery. The
charging indicator lamp will blink
rapidly when this is occurring.
To reduce the risk of electrical
shock, do not touch any high
voltage components (orange) or
other electrical devices while
charging is occurring.

Starting the Hybrid System
1.Carry the smart key into the vehicle.
2.Make sure the parking brake isfirmly 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 with- out pressing the accelerator. In
extremely cold weather or after the
vehicle has not been operated for
several days, let the engine warm up
without depressing the accelerator.
vehicle, if it is far away from you,
the engine may not start.
ton is 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 indica-
tor will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC posi-
tion or if the vehicle engine is on. If the starting procedure is fol-
lowed, the " " symbol on the
instrument cluster will turn on. For
more details, Please check chap-
ter 4.

ECONOMICAL and SAFE
OPERATION of Hybrid system
Drive smoothly. Accelerate at amoderate rate and maintain a
steady cruising speed. Don't make
"jack-rabbit" starts. Don't race
between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine runs in "N" posi- tion, the hybrid system cannot gen-
erate electricity. The hybrid battery
cannot recharge in "N" position.
Please refer to chapter 6.
✽ ✽ NOTICE
When the hybrid system is in ready
mode, the engine will automatically
start and stop as needed.
The " " symbol will illuminate in
the cluster when the system is oper-
ational.
CAUTION - Extended
cranking
Do not crank the engine for aprolonged period of time with-out the engine starting. Thiscould result in damage to theHEV battery and becomingtotally discharged.

H40
The Hybrid battery uses high voltage
to operate the electric motor and
other components and other compo-
nents. High voltage is dangerous if
touched.
Your vehicle is equipped with orange
colored insulation and covers over
the high voltage components to pro-
tect people from electric shock. High
voltage warning labels are attached
to some system components as addi-
tional warnings. Have your vehicle
serviced by an authorized Kia dealer.
WARNING - High voltage
components
Never touch orange or high
voltage labeled components
including wires, cables, and
connections. If the insulators or
covers are damaged or
removed, severe injury or death
from electrocution may occur.
WARNING - Touching
HPCU
When replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU could result in electrocu-
tion, serious injury, or death.
