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.

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.

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,
