Features of your vehicle
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air fil-
ter replaced by an authorized Kia
dealer.
✽ ✽NOTICE
• Replace the filter every 15,000
miles or once a year.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.

WARNING
The oil and refrigerant in your
vehicle's air conditioning sys-
tem is under very high pres-
sure. If proper service proce-
dures are not followed an explo-
sion may result. To reduce the
risk of serious injury or death,
the air conditioning system in
your vehicle should only be
serviced by trained and certi-
fied technicians.

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
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 transaxle occurs,
check the transaxle fluid level.
Check the automatic transaxle 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.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and reinsert it fully. 5. Pull the dipstick out again and
check the level. The level should
be between F and L.
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” in chapter 9.)
CAUTION - Replacing
engine oil
Do not overfill the engine oil. Itmay damage the engine.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 9.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
OJFH075166CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

Specifications, Consumer information, Reporting safety defects
Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant. This is especially impor-
tant in dusty or sandy areas and when
the vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged. Engine oil vis-
cosity (thickness) has an effect on fuel
economy and cold weather operating
(engine start and engine oil flowabili-
ty). Lower viscosity engine oils can
provide better fuel economy and cold
weather performance; however, high-
er viscosity engine oils are required
for satisfactory lubrication in hot
weather. Using oils of any viscosity
other than those recommended could
result in engine damage. When
choosing an oil, consider the range of
temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended
oil viscosity from the chart.
*1: For better fuel economy, it is recommended to use the engine oil ofa viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
