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.

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.

5-5
DRUNK DRIVINGDrinking and driving is dangerous. Drunk
driving is the number one contributor to
the highway death toll each year. Alcohol
impairs a driver’s judgment, vision and
muscular coordination. Even a small
amount of alcohol will affect a driver’s
reflexes, perceptions and judgment.
Please don’t drink and drive, or ride with
a driver who has been drinking. Choose
a designated driver if you’re with a
group, or if you’re alone, call a cab.
DRUGS AND DRIVINGDriving while under the influence of
drugs is as dangerous or more dangerous
than driving under the influence of
alcohol, depending on the drug(s) used
and the quantity consumed. Don’t take
drugs and drive.
If you are taking a prescription medicine,
check with your doctor or pharmacist
regarding whether you may operate a
motor vehicle.
SUGGESTIONS FOR
ECONOMICAL
OPERATIONYour vehicle’s fuel economy is mainly
dependent on your style of driving, how
you drive, where you drive and when
you drive.
Each of these factors has an effect on
how many miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as possible,
use the following driving suggestions to
help save money in both fuel and repairs:
 Avoid lengthy warm-up idling. Once
the engine is running smoothly, begin
driving. Remember, though, that on
cold days, engine warm-up may take
a little longer.
 Save fuel by accelerating slowly after
stopping.
MS-CNA-Eng 5 New.qxd 7/25/2005 5:21 PM Page 5

 Keep the engine in tune and follow the
recommended periodic maintenance
schedule.
This will increase the life of all parts
and lower your operating costs.
 Do not use the air conditioner
unnecessarily.
 Slow down when driving on rough
roads.
 For longer tire life and better fuel
economy, always keep the tires
inflated to the recommended
pressures.
 Maintain a safe distance from other
vehicles to avoid sudden stops. This
will reduce wear on brake linings and
pads and save fuel because extra fuel
is required to accelerate back to
driving speed.
 Do not carry unnecessary weight in
the vehicle. Do not rest your foot on the brake
pedal while driving. This can cause
needless wear, possible damage to
the brakes, and poor fuel economy.
 Improper wheel alignment causes the
tires to roll at excessive angles,
which results in faster tire wear. It
takes more power to overcome this
improper alignment, which wastes
fuel.
 Open windows at high speeds can
reduce fuel economy.
 Crosswinds and headwinds reduce
fuel economy. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating
condition is important both for
economy and safety.
Therefore, have an Authorized Kia
Dealer perform scheduled inspections
and maintenance.
DRIVING TIPS
5-6
WARNING - Engine OFF
Motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function without the engine
running. Instead, downshift to
any appropriate gear for engine
braking effect.
MS-CNA-Eng 5 New.qxd 7/25/2005 5:21 PM Page 6

SPECIAL DRIVING
CONDITIONSHAZARDOUS DRIVINGWhen hazardous driving is encountered
because of water, snow, ice, mud, sand, or
similar hazard, follow these suggestions:
 Drive cautiously and allow extra
distance for braking.
 Avoid sudden movements in braking
or steering.
 When braking in vehicles without
anti-lock brakes, depress the brake
pedal with a controlled up-and- down
motion until the vehicle is stopped.
 When starting from a stop in snow,
mud, or sand, use second gear and
accelerate slowly to avoid spinning
the front wheels. Low gear may be
used, if necessary.
 Use sand, rock salt, tire chains, or
other non-slip material under the
front wheels to provide traction when
stalled on ice, snow, or mud.
ROCKING THE VEHICLEIf it is necessary to rock the vehicle to
free it from snow, sand, or mud, move
the shift lever of an automatic transaxle
from D (Drive) to R (Reverse) in a
repeat pattern while depressing the
accelerator gently. With a manual
transaxle, move the shift lever back and
forth from 1 (First) to R (Reverse).
Do not race the engine. If you are still
stuck after a couple minutes of rocking,
have the vehicle pulled out by a tow
vehicle to avoid engine overheating and
possible damage to the transaxle.
5-7
WARNING -
Downshifting
Downshifting into first gear with
a manual transaxle or into low
with an automatic transaxle
while driving on slippery
surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when
downshifting on slippery
surfaces.
✻
NOTICE
Prolonged rocking may cause
engine overheating, transaxle
damage or failure, and tire
damage.

5-9
 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

ROAD WARNINGHAZARD WARNING FLASHERThe hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It
should be used whenever emergency
repairs are being made or when the vehicle
is stopped near the edge of a roadway.Depress the flasher switch with the
ignition switch in any position.
All turn signal lights will flash
simultaneously.
• The hazard warning flasher will
operate whether your vehicle is
running or not.
 The turn signals do not operate when
the hazard flasher is on.
 Care must be taken when using the
hazard warning flasher while the
vehicle is being towed. Local
regulations may prohibit using it in
this manner.
OVERHEATINGIf your temperature gauge indicates
overheating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. You should follow these
procedures if you experience any of
these symptoms.
1. Turn the hazard warning flasher on,
then drive to the nearest safe location
and stop your vehicle; set the
automatic transaxle in P (Park), or
shift the manual transaxle to neutral
and apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of
the radiator, stop the engine, then
turn the ignition switch to the ON
position. Do not restart the engine.
The radiator cooling fan will
automatically operate with the
ignition switch in the ON position. If
the cooling fan does not operate, call
an Authorized Kia Dealer for
IN CASE OF EMERGENCY

assistance. If coolant is not boiling
out, allow the engine to idle and open
the hood to permit the engine to cool
gradually. If the temperature does not
go down with the engine idling, stop
the engine and allow sufficient time
for it to cool.
4. The coolant level should then be
checked. If the level in the reservoir
is low, look for leaks at the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump. If you find a major leak or
another problem that may have
caused the engine to overheat, do not
operate the engine until the problem
has been corrected. Call an
Authorized Kia Dealer for assistance.
If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, have
the cooling system checked and repaired.
EMERGENCY STARTINGJUMP STARTINGJump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting
procedures on the next page. If in doubt,
we strongly recommend that you have a
competent technician or towing service
jump start your vehicle.
6-3
WARNING - Removing
Radiator Cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause
serious injury.
✻
NOTICE
Use only a 12volt jumper system.
You can damage a 12volt starting
motor, ignition system, and other
electrical parts by using a 24-volt
power supply (two 12-volt batteries
in series or a 24-volt motor
generator set).
