OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized Kia dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
roads.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.

FUSES
❈Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will melt.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
Do not arbitrarily modify or add-on electric wiring to the vehicle.
WARNING- Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

✽ ✽
NOTICE
• When replacing a fuse, turn the
ignition “OFF” and turn off
switches of all electrical devices
then remove battery (-) terminal.
• The actual fuse/relay panel label may differ from equipped items.
WARNING- Electrical Fire
Always ensure replacements
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
CAUTION
When replacing a blown fuse or relay, make sure the newfuse or relay fits tightly intothe clips. Failure to tightlyinstall the fuse or relay maycause damage to the wiringand electric systems.
Do not remove fuses, relays and terminals fastened withbolts or nuts. The fuses, relaysand terminals may not be fas-tened correctly which maycause vehicle damage.
CAUTION
Do not input any other objects except fuses or relays intofuse/relay terminals, such as adriver or wiring. It may causecontact failure and systemmalfunction.
Do not plug in screwdrivers or aftermarket wiring into the ter-minal originally designed forfuse and relays only. The elec-trical system and wiring of thevehicle interior may be dam-aged or burned due to contactfailure.
If you directly connect the wire on the taillight or replacethe bulb which is over the reg-ulated capacity to install trail-ers, etc., the inner junctionblock can get burned.

LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specifiedwattage. net-work failure
The headlamp, taillight, and fog light
may light up when the head lamp
switch is turned ON, and not light up
when the taillight or for light switch is
turned ON. This may be cause by net-
work failure or vehicle electrical control
system malfunction. If there is a prob-
lem, we recommend the system be
serviced by an authorized Kia dealer.
trical control system stabilization
A normally functioning lamp may
flicker momentarily. This momentary
occurrence is due to the stabilization
function of the vehicle's electrical
control system. If the lamp stops
flickering after a few moments, the
vehicle does not require service.
However, if the lamp goes out after
the momentary flickering, or the flick-
ering continues, we recommend the
system be serviced by an authorized
Kia dealer.
WARNING- Working on the lights
Prior to working on the lights,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle that may cause burning
your fingers or receiving an
electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.

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
driving, 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 mate-
rials. 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 performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward
speed.

Corrosion protection
Protecting your vehicle from corrosion
By using advanced design and con-
struction practices to combat corro-
sion, we produce vehicles of excel-
lent quality. However, this is only part
of the job. To achieve the long-term
corrosion resistance your vehicle can
deliver, the owner's cooperation and
assistance is also required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
Removal of paint or protective coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion. High-corrosion areas
If you live in an area where your vehi-
cle is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated cor-
rosion are road salts, dust control
chemicals, ocean air and industrial
pollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to
occur. For example, corrosion is
accelerated by high humidity, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact with the vehicle’s surface by
moisture that evaporates slowly.
Mud is particularly corrosive
because it dries slowly and holds
moisture in contact with the vehicle.
Although the mud appears to be dry,
it can still retain the moisture and
promote corrosion.WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
