ENGINE TEMPERATURE
GAUGEThis gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
If the gauge pointer moves beyond the
normal range area toward the H position,
it indicates overheating that may damage
the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “Overheating” in the
Index.
WARNINGS AND
INDICATORSWARNING LIGHTS/
AUDIBLE INDICATORSCHECKING OPERATIONAll the warning lights, except the brake
warning light, are checked by turning the
ignition switch ON (you do not need to
start the engine). Any light that does not

MALFUNCTION
INDICATOR LIGHT
(IF EQUIPPED)The CHECK ENGINE or malfunction
indicator light is installed in your
vehicle’s instrument panel and responds
to signals from the vehicle’s On Board
Diagnostic (OBD -II) System. The OBD-
II System monitors the performance of the
vehicle’s Emission Control System
(ECS), which is designed to reduce the
amount of air pollutants in engine exhaust
to the levels required by government
regulations.
When you first start the engine, the check
engine light will illuminate briefly as a
system check to confirm that the OBD-II
System is operating properly. As the
engine starts, this light turns off.
However, if at any time the OBD-II
system detects a faulty signal or
determines that the ECS is not performing
to specification, the CHECK ENGINE
light will illuminate continuously or flash.
Continuously ON :If the CHECK ENGINE light comes ON
while driving and illuminates continuously,
a potential problem has been discovered in
the ECS or one of the exhaust system
components. Generally, the vehicle will
continue to be driveablebut it should
be checked by an Authorized Kia Dealer
as soon as possible. This condition is
unlikely to lead to engine damage unless
a decrease in vehicle power or poor
running conditions is immediately
apparent.
Flashing ON and OFF :If the CHECK ENGINE light begins to
flash ON and OFF, a more serious
problem with the ECS or exhaust system
component has been detected. If this
happens, and there is no degradation
to performance, the vehicle is still
driveable(avoid high speeds) but should
be checked by an Authorized Kia Dealer
at your earliest possible convenience. If
the flashing CHECK ENGINE light is
accompanied by a decrease in power or
poor running conditions, safely stop the
vehicle and immediately contact Kia
Roadside Assistance.
Note that the CHECK ENGINE light
will illuminate for a problem like a loose
or missing gas cap, but will not
illuminate as a result of low engine oil or
coolant, low automatic transaxle fluid or
engine overheating. The driver will be
alerted to these conditions by other
indicators on the instrument panel.

(Continued)
• If you have to use to the electri-
cal accessories that draw higher
power (vacuum cleaner, lights,
cooler, etc.) only use the power
outlet intermittently and with
greater caution.
• Long periods of the vehicle not
being started (with electrical
accessories plugged in) will dis-
charge the vehicle’s battery and
degrade the battery life.
• Cap the cover of power outlet
when not in use.
• Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static and
malfunctions in other electronic
systems or devices used in your
vehicle.
✻
NOTICE
• Do not hold the lighter in
because it will overheat.
• Only a genuine Kia lighter
should be used in the cigarette
lighter socket. The use of plug-in
accessories (shavers, hand-held
vacuums and coffee pots, for
example) may damage the socket
or cause electrical failure.
• If the lighter does not pop out
within 30 seconds, remove it to
prevent overheating.

KNOBThe temperature control knob (C) is the
round knob closest to the passenger side
of the ventilation control panel. To
change the air temperature in the
passenger compartment, turn the knob
either clockwise for warm to hot air or
counterclockwise for cooler air.
AIR INTAKE
CONTROL SWITCHThis is used to select fresh outside air or
recirculation inside air.
RECIRCULATED AIR
POSITION When the air intake control
switch is depressed (switch indicator
illuminates), almost all outside air flow
into the vehicle is shut off and air inside
the vehicle is recirculated.
This position can be used temporarily for
maximum heating or cooling (if
equipped with air conditioning ) and to
help prevent undesirable outside air flow
into the vehicle.
WARNING
• Continued climate control
system operation in the
recirculated air position may
allow humidity to increase
inside the vehicle which may
fog the glass and obscure
visibility.
 Don’t sleep in a vehicle with
the air conditioning system
on. This could cause serious
harm or death to passengers
due to the depletion of
oxygen and lowering of body
temperature.
