Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation, and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (for gasoline)
Kia gasoline vehicles are equipped
with a lifetime fuel filter that inte-
grates with the fuel tank. Regular
maintenance or replacement is not
needed but depends on fuel quality. If
there are some important safety mat-
ters like fuel flow restriction, surging,
loss of power, hard starting problem,
etc., fuel filter inspection or replace is
needed.
The fuel filter be inspected or
replaced by an authorized Kia dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized Kia dealer
replace any damaged or leaking
parts immediately.
Fuel tank and fuel cap
The fuel tank and fuel cap should be
inspected at the intervals specified in
the maintenance schedule. Make
sure that a new fuel tank and fuel
cap is installed correctly.

Maintenance
 Underinflation also results inexcessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized Kia dealer.
 Overinflation produces a harsh ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards.
 Warm tires normally exceed rec- ommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
 Be sure to reinstall the tire inflation valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.Tire pressure
Always observe the following:
 Check tire pressure when the tiresare cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1
mile (1.6 km) since startup.)
 Check the pressure of your spare tire each time you check the pres-
sure of other tires.
 Never overload your vehicle. Be careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You cannot tell if your
tires are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they're underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1 mile (1.6 km).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.

Maintenance
Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and definitions
Air Pressure:
The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, intelligent variable
transmission, power seats, and air
conditioning.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure:
The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.

Maintenance
EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty & Consumer Information
manual in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
There are three emission control
systems, as follows.
(1) Crankcase emission control sys-tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized Kia dealer in accor-
dance with the maintenance sched-
ule in this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
 To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
 After dynamometer testing is completed, turn the ESC system
back on by pressing the ESC
switch again.1. Crankcase emission control system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission con-trol (including ORVR:
Onboard Refueling Vapor
Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
(The ORVR system is designed to
allow the vapors from the fuel tank to
be loaded into a canister while refu-
eling at the gas station, preventing
the escape of fuel vapors into the
atmosphere.)

To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1:Refer to the recommended SAE viscosity numbers on the next page.
*2:Requires < API SN PLUS (or above) Full synthetic> grade engine oil. If a lower grade engine oil (mineral oil including
Semisynthetic) is used, then the engine oil and engine oil filter must be replaced as indicated severe maintenance condition.
*3:Use only specified genuine Intelligent Variable Transmission(IVT) fluid. The use of non-specified fluid (even marked as compat-
ible with genuine) could result in shift quality deterioration and vibrations, eventually, the transmission failure.(Refer to
“Explanation of Scheduled Maintenance Items” in chapter 7.)
