TCS ON/OFF MODEIn the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
The indicator will illuminate when the
ignition key is turned to the “ON”
position, but it should go off after 3
seconds. It means the TCS is in the stand-
by status and at the moment of the actual
operation of the TCS, the indicator will
blink.
To switch to TCS OFF mode, press the
TCS switch. System will be deactivated
and the TCS indicator in the instrument
cluster will illuminate.
If the TCS indicator stays on in the TCS
ON mode, take your car to your
Authorized Kia Dealer and have the
system checked.
✻
NOTICE
• The TCS ON mode is activated
automatically when the engine is
started.
 When the TCS is operating
properly, you may feel a slight
pulsation in the vehicle. This is
only the effect of brake control
and is not unusual.
 When the engine starts, your
may hear a “click” sound from
the engine compartment. This is
only the sound of the TCS being
checked.
 When moving out of mud or
fresh snow with the TCS ON,
pressing the accelerator pedal
may not cause the engine speed
to increase.

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.

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.

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.

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.

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).

4. Turn off all unnecessary electrical
loads.
5. Connect the jumper cables in the exact
sequence shown in the illustration on
the previous page.
First, connect one end of a jumper
cable to the positive terminal (+) of
the discharged battery , then the
other end of the same cable to the
positive terminal (+) on the booster
battery, . Next, connect one end of
the other jumper cable to the negative
terminal (-) of the booster battery ,
then the other end to a solid,
stationary, metallic point (for
example, the engine lifting bracket) 
away from the battery. Do not connect
the jumper cable to or near any part
that moves when the engine is
cranked. Do not connect the jumper
cable from the negative terminal (-) of
the booster battery to the negative
terminal (-) of the discharged battery.Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the battery
when making connections.
6. Start the engine of the vehicle with
the booster battery and run it at 2,000
rpm. Then, start the engine of the
vehicle with the discharged battery.
If the cause of your battery discharging
is not apparent (for example, having left
the lights on accidentally), you should
have your vehicle checked by an
Authorized Kia Dealer.
PUSH-STARTINGA vehicle equipped with an automatic
transaxle cannot be started by pushing. A
vehicle equipped with a manual transaxle
should not be push-started because it
could damage the emission control
system. Follow the directions for jump
starting.
IN CASE OF EMERGENCY
6-6
CAUTION
Never tow a vehicle to start it. A
sudden surge forward when the
engine starts could cause a collision
with the tow vehicle.

ELECTRICAL CIRCUIT
PROTECTIONFUSESA vehicle’s electrical system is protected
from electrical overload damage by fuses.
This vehicle has two fuse panels, one
located in the driver’s side kick panel, the
other in the engine compartment near the
battery. A fuse panel chart is provided
later in this section.If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted. Always replace a
blown fuse with one of the same rating.
If the replacement fuse blows out, this
indicates an electrical problem. Avoid
using the system involved and
immediately consult an Authorized Kia
Dealer.
Two kinds of fuses are used: standard for
lower amperage rating, and main for
higher amperage ratings.
FUSE REPLACEMENTIf the electrical system does not work,
first check the driver’s side fuse panel.

WARNING - Fuse
Replacement
 Never replace a fuse with
anything but another fuse of
the same type and rating.
 A higher capacity fuse could
cause damage and possibly
a fire.
 Never install a wire in place
of the proper fuse - even as a
temporary repair. It may
cause extensive wiring
damage and possibly a fire.
 Do not use a screwdriver or
any other metal object to
remove fuses because it may
cause a short circuit and
damage the system.
