DRIVING YOUR VEHICLE
4-52AIR CONDITIONING
SYSTEM OPERATING
TIPS:• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time to
let hot air inside the vehicle escape.
• To help reduce moisture on the inside
of windows on rainy, humid days,
decrease the humidity inside the
vehicle by operating the air
conditioning system.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed at idle as the A/C compressor
cycles ON. This is a normal system
operating characteristic.
• Use the air conditioning system every
month if only for a few minutes.
• After air conditioning system use,
you may notice clear water dripping
(or even puddling) on the ground
under the passenger side of the
vehicle. This is a normal system
operating characteristic.• The air conditioning system includes
a function that will automatically turn
the A/C compressor OFF if engine
coolant temperature approaches an
overheating level. A/C compressor
operation will resume once engine
coolant temperature returns to the
“normal” range. Also, the A/C
compressor is automatically turned
off for a few seconds when the
accelerator is fully depressed.
• When operating the air conditioning
system use the outside (fresh) air
position.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

REAR HEATER DUCT
(IF EQUIPPED)Whenever the ventilation controls are in
the face-floor or floor position, air is
directed to the rear seat passenger floor
area.AIR QUALITY CONTROL
SYSTEM (IF EQUIPPED)The air inflow from the outside of the
vehicle can be automatically controlled.
Press the button to activate the “Air
Quality Control System”. To deactivate
the system, press the button or air
intake control button or set modes
selection knob to position.
When using AQS mode, AQS(Air
Quality Control System) automatically
senses outdoor air pollutants and
minimizes them from entering the
vehicle, however, unpleasant or foul
odors that might be present may still be
noticeable within the vehicle.
CAUTION
 Prolonged driving with “Air
Quality Control System” ON
will cause frosting inside the
vehicle.
 To defrost the vehicle, set the
mode selection knob to Defrost
( ) position or the air intake
button to the outside position.
 The air quality control sensor is
located at the side of the radia-
tor. Be careful to avoid damag-
ing the sensor.

• Before driving, clear all snow and ice
from the windshield, rear window,
outside rear view mirrors, and all side
windows.
• Clear all snow and ice from the hood
and the air inlet in the cowl grille to
improve heater and defroster
efficiency and to reduce the
probability of fogging on the inside
of the windshield.DRIVING YOUR VEHICLE

DRIVING TIPS
5-2FUEL REQUIREMENTSYour new Kia Vehicle must use only
UNLEADED FUEL having an octane
rating of 87 or higher. Your new Kia is
designed to obtain maximum performance
with unleaded fuel. Unleaded fuel will
minimize exhaust emissions and spark
plug fouling.
GASOLINE CONTAINING
ALCOHOL AND METHANOLEthanol (also known as grain alcohol) is
a mixture of ethanol and gasoline
marketed as gasohol. Do not use gasohol
containing more than 10% ethanol.
Methanol (also known as wood alcohol)
is a mixture of gasoline and methanol
marketed as gasohol. Do not use gasoline
or gasohol containing methanol.
Either of these fuels may cause
driveability problems and damage to the
fuel system.
Discontinue using gasohol of any kind if
driveability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufacturer’s
warranty if they result from the use of:
 Gasohol containing more than 10%
ethanol,
 Gasoline or gasohol containing
methanol, or
 Leaded fuel or leaded gasohol
✻
NOTICE
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter. Never add
any fuel system cleaning agents to
the fuel tank other than what Kia
has specified or the equivalent.
(Consult an Authorized Kia Dealer
for details.)
Leaded fuel will damage the engine
control system’s oxygen sensor and
affect the emission control system.
✻
NOTICE
Never use gashol which contains
methanol. Discontinue use of any
gashohol product which impairs
driveability.
MS-CNA-Eng 5 New.qxd 7/25/2005 5:21 PM Page 2

5-3
EMISSION CONTROL
SYSTEM The vehicle emission control system is
covered by a written limited warranty.
Please see the warranty & consumer
information manual in your vehicle.VEHICLE MODIFICATIONSThis vehicle should not be modified.
Modification of your Kia could affect its
performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
ENGINE EXHAUST GAS
PRECAUTIONS
(CARBON MONOXIDE)Engine exhaust gases contain carbon
monoxide. Though colorless and
odorless, it is dangerous and could be
lethal, if inhaled.
 Carbon monoxide can be present
with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your
vehicle, have it inspected and
repaired immediately by an
Authorized Kia Dealer. If at all
possible, do not drive with exhaust
fumes present. If you must, do so
only with all windows fully open.
Have your vehicle checked and
repaired immediately.
 Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area. When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system to draw outside air
into the vehicle.
Turn the engine off if you smell any
exhaust fumes.
 Never sit in a parked or stopped
vehicle for an extended time with the
engine running.
 When the engine stalls or fails to
start, excessive attempts to re-start
the engine may cause damage to the
emission control system.
OPERATING PRECAUTIONS
FOR CATALYTIC CONVERTERSYour vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
 Use only UNLEADED FUEL.
 Do not park the vehicle over or near
flammable objects, such as dry grass,
paper, leaves, etc. Under certain
conditions, they could be ignited by a
hot exhaust system.
MS-CNA-Eng 5 New.qxd 7/25/2005 5:21 PM Page 3

DRIVING TIPS
5-4 Do not operate the vehicle when
there are signs of engine malfunction,
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 control
system. All inspections and
adjustments must be made by a
qualified technician.
Failure to observe the above precautions
could result in damage to the catalytic
converter and to your vehicle and could
void your warranties.
BEFORE DRIVINGBefore entering vehicle:
 Be sure that all windows, outside
mirror(s), and outside lights are clean.
 Check the condition of the tires.
 Check under the vehicle for any sign
of leaks.
 Be sure there are no obstacles behind
you if you intend to back up.NECESSARY
INSPECTIONSFluid levels, such as engine oil, engine
coolant, brake/clutch fluid, and washer
fluid should be checked on a regular
basis, with the exact interval depending
on the fluid. Further details are provided
in Maintenance, Section 7.
BEFORE STARTING Close and lock all doors.
 Position the seat so that all controls
are easily reached.
 Adjust the inside and outside
rearview mirrors.
 Be sure that all lights work.
 Check all gauges.
 Check the operation of warning
lights when the ignition switch is
turned to the ON position.
 Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
