Features of your vehicle
Each symbol and specification on
the air conditioning refrigerant label
is represented below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
4. Caution
5. Flammable Refrigerant
6. To requires Registered Technician
to Service Air Conditioning system
Refer to chapter 8 for more detail on
the location of air conditioning refrig-
erant label.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.
ODEP089004L
CAUTION - AC Repair
It is important that the correct
type and amount of oil and
refrigerant is used, otherwise
damage to the vehicle may
occur. To prevent damage, the
air conditioning system in your
vehicle should only be serviced
by trained and certified techni-
cians.

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

Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important 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.
CHECKING FLUID LEVELS

719
Maintenance
ENGINE OIL
Checking the engine oil level
Engine oil is used for lubrication
and cooling, so it is gradually con-
sumed during driving the vehicle.
Regularly check and manage the
oil level using the following proce-
dure.
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 15 minutes.
(with oil filler cap and dipstick
detached)) for the oil to return to
the oil pan.
4. Pull the dipstick out, wipe it clean,
and reinsert it fully.5. Check if the oil level is between
the F-L line and refill it if the oil
level is near the L line.
CAUTION - Replacing
engine oil
Do not overfill the engine oil. It
may damage the engine.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding 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.Periodically check that the fluid level
in the brake fluid reservoir is
between MIN and MAX. 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 lubricants
and capacities” in chapter 8.)
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.
CAUTION - Brake fluid
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result.
CAUTION - Proper fluid
Only use brake fluid in brake
system. Small amounts of
improper fluids (such as engine
oil) can cause damage to the
brake system.

ENGINE CLUTCH ACTUATOR FLUID
Checking the engine clutch
actuator fluid level
In normal driving conditions, the
actuator fluid level does not go down
rapidly. However, oil consumption
rate may rise as vehicle mileage
increases, and leakage in actuator
related parts may result in increased
consumption of the engine clutch
actuator oil. Regularly check and
make sure the engine clutch actuator
oil fluid level is between [MIN] and
[MAX] marks.
If the oil level is below [MIN] mark,
we recommend that your vehicle be
checked by an authorized Kia dealer.If the fluid level is excessively low, we
recommend that the system be
checked by an authorized Kia dealer.
Use only the specified engine clutch
actuator fluid.
(Refer to “Recommended lubricants
or capacities” in chapter 8.)
Never mix different types of fluid.
✽ ✽
NOTICE - Loss of engine
clutch actuator fluid
In the event the engine clutch actua-
tor requires frequent additions of
fluid, we recommend that the system
be inspected by an authorized Kia
dealer.
WARNING- Engine clutch
actuator fluid
When changing and adding
engine clutch actuator fluid,
handle it carefully. Do not let it
come in contact with your eyes.
If engine clutch actuator fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh water, and seek medical
attention as soon as possible.
