Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or replace-
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright- metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of yourvehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the undercarriage at the end of the
winter.
Use professional service techni- cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
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.

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.)

8103
Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

8105
Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL forgasoline engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.
Do not operate the engine at high idle speed for extended periods (5
minutes or more).
Do not modify or tamper with any part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter. Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

RECOMMENDED LUBRICANTS AND CAPACITIES
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.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*
3If the API SM engine oil is not available, you can use API SN or above.
*4If the ILSAC GF-4 engine oil is not available, you can use ILSAC GF-5 or above.

Recommended SAE viscosity
number
Engine oil viscosity (thickness) has an
effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosity
engine oils can provide better fuel
economy and cold weather perform-
ance; however, higher viscosity
engine oils are required for satisfacto-
ry lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage. When choosing an oil, con-
sider the range of temperature your
vehicle will be operated in before the
next oil change. Proceed to select the
recommended oil viscosity from the
chart.
