✽NOTICE
• If the memory fuse is pulled up from
the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to
“Battery” in this section.
• Even when the memory fuse is pulled up, the battery can still be discharged
by operation of the headlights or other
electrical devices.
Engine compartment panel fuse
replacement
1. Turn the ignition switch and all other switches off.
2. Remove the fuse box cover by press- ing the tap and pulling up the cover.
3. Check the removed fuse; replace it if it is blown. To remove or insert the fuse,
use the fuse puller in the engine com-
partment fuse panel.
4. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized
Kia dealer.
CAUTION - Fuse panel
covers
After checking the fuse panel in theengine compartment, securely install the fuse panel cover to pre-vent electrical failures which mayoccur from water leaking in.

APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
After washing the vehicle, test the brakes
while driving slowly to see if they have
been affected by water. If braking per-
formance is impaired, dry the brakes by
applying them lightly while maintaining a
slow forward speed.WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
water enters the engine or hybrid
battery in the trunk, electric shocks
or burns may result in serious
injury or death.

H2
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.

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.
