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 coolant
reservoir.
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
road.
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 dual clutch 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.

Maintenance

At least monthly:
Check the coolant level in the
engine coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.

tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year

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 higher
amperage 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 any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

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 specified
wattage.✽ ✽
NOTICE
• If the light bulb or lamp connector
is removed while the lamp is still
on, the fuse box's electronic sys-
tem may log it as a malfunction.
Therefore, a lamp malfunction
incident may be recorded as a
Diagnostic Trouble Code (DTC) in
the fuse box.
• It is normal for an operating lamp
to flicker momentarily. This is due
to a stabilization function of the
vehicle’s electronic control device.
If the lamp lights up normally
after momentarily blinking, then
it is functioning as normal.
However, if the lamp continues to
flicker several times or turns off
completely, there may be an error
in the vehicle’s electronic control
device. Please have the vehicle
checked by an authorized Kia
dealer immediately.
✽ ✽
NOTICE
We recommend that the headlight
aiming be adjusted by an authorized
Kia dealer after an accident or after
the headlight assembly is reinstalled.
WARNING- Working on
the lights
Prior to working on the light,
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 and burning your fingers
or receiving an electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do not
clean the headlamp lens with
chemical solvents or strong
detergents.

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.
✽ ✽
NOTICE
If you park the vehicle around a
stainless signboard or windshield
building etc., the plastic exterior
trim (bumper, spoiler, garnish,
lamp, outside mirror etc.) may be
damaged by reflected sunlight from
the external structure. To avoid
damaging the plastic exterior trim,
park the vehicle away from the
areas where the reflected light may
occur or use a vehicle cover
(Depending on the vehicle, the type
of exterior trim applied such as
spoiler may differ).
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.

Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
Do not use any abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
Avoid washing the wheels with high-
speed vehicle wash brushes.
Do not use any alkaline or acid
detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, we produce vehicles of
the highest 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.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.
